Therapeutic Massage Device

The present invention relates to therapeutic massage devices. More specifically, the present invention relates to therapeutic massage devices for use in physiotherapy or other similar professions, and to methods of carrying out physiotherapy treatments.

Musculoskeletal pain affects the muscles, ligaments, tendons and bones of a sufferer. Causes of musculoskeletal pain are varied, and can be caused due to damage afflicted on muscle tissue during the wear and tear of normal daily activities. Alternatively, musculoskeletal pain can be caused by trauma to an area, and this could be the result of a direct blow to a muscle, which could be caused by a fall or a car crash for instance.

Currently, a person suffering from musculoskeletal pain may need to see a

physiotherapist or other similar professional, to hasten his or her recovery. The physiotherapist may treat the affected area using a myofascial treatment, whereby the physiotherapist applies appropriate force to the tissue, typically using their knuckles or forearm. Alternatively, the physiotherapist may decide a precision treatment is more appropriate and use their fingers to gently massage the affected area. Applying the treatment can be physically demanding for the physiotherapist and as a result quite a number of physiotherapists suffer from repetitive strain disorder. Accordingly, there is a need to develop a device which will allow a physiotherapist or other similar professional, to treat a patient without injuring themselves in the process.

Additionally, it is not always possible for a person suffering from musculoskeletal pain to visit a physiotherapist as regularly as may be required. Accordingly, there is also a need to develop a device or system which will allow a person to access treatment when they are unable to visit a physiotherapist.

There is therefore a need to provide alternative and improved apparatus for carrying out physiotherapy or massage.

In accordance with a first aspect of the invention, there is provided a therapeutic massage device comprising a reservoir filled, or adapted to be filled, with a massage formulation, and delivery means disposed in functional communication with the reservoir, and configured to release massage formulation upon application of pressure thereto. Advantageously, and preferably, the massage device is configured to be held by an operator (preferably, by one hand, or by one hand and supported and/or guided by the other hand), thereby allowing the operator to massage and treat a subject without risking repetitive strain injury to their thumbs.

A "subject" maybe a vertebrate, mammal, or domestic animal. Hence, the device may be used to treat any mammal, for example livestock (e.g. a horse), pets, or maybe used in other veterinary applications. Hence, the operator may be a vet. Most preferably, however, the subject is a human being. Accordingly, the operator maybe a

physiotherapist. However, an advantage of the device is that it can be held by the subject him/herself, or a friend. Accordingly, a person can use the device to treat themselves or someone else.

Preferably, the delivery means is configured to deliver massage formulation to the subject while being used to massage the subject. The massage formulation may comprise massage oil, massage cream or massage gel. The formulation may comprise an oil-based liquid or gel, for example Deep Heat® heat rub or Deep Freeze® cold gel. However, in a preferred embodiment the formulation comprises an emulsion, preferably a body lotion.

Preferably, the delivery means is removably attached to the reservoir, thereby allowing a user to replenish the massage formulation when the reservoir is empty. Preferably, the delivery means comprises a moveable curved member which is supported by support means substantially adjacent to the reservoir, and is configured to be moved along a portion of a subject's body, and thereby deliver massage formulation thereto. The curved member preferably comprises a curved surface, which is arranged, in use, to contact the subject's body and deliver formulation thereto. Preferably, the curved member is rotatable. Preferably, the curved member possesses at least one degree of rotational freedom relative to the reservoir. Preferably, the at least one degree of rotational freedom allows for pitch and/ or roll rotation of the curved member relative to the reservoir. For example, the curved member may comprise a cylinder, which is configured to rotate around its longitudinal axis. However, most preferably, the curved member comprises a sphere, which is preferably configured to rotate around 360 °. Preferably, the curved member possesses three degrees of rotational freedom relative to the reservoir, allowing for pitch, roll and yaw rotations of the curved member relative to the reservoir. Advantageously, the sphere acts as a roller ball, which can be rolled over the area of the subject's body requiring treatment by massage.

Preferably, the support means is removably attached to the reservoir, and preferably comprises an aperture through which the curved member extends. Hence, preferably the curved member is disposed adjacent to the reservoir and extends through the aperture and is adapted to deliver massage formulation therethrough. The support means may comprise a collar having one or more struts extending therefrom and which are arranged to support the curved member.

In one embodiment, the curved member is configured to move between a first position in which it abuts the aperture to create a seal which prevents massage formulation from passing therethrough, and a second position in which it is spaced apart from the aperture thereby breaking the seal, such that massage formulation can pass

therethrough. Preferably, a portion of the support means comprises an elastic material (e.g. rubber, an elastomer, or a thermoplastic elastomer (TPE)), wherein the portion is adjacent to and defines the aperture, such that when the curved member is in the first position, the seal is created due to the contact between the curved member and the portion. The support means is preferably configured to urge the curved member towards the first position, when no external force is applied. Hence, advantageously, due to the seal created between the curved member and the aperture, the therapeutic massage formulation stored in the reservoir does not leak when the massage device is not in use. Preferably, however, upon application of external force to the curved member, the support means is configured to urge the curved member into the second position such that the seal is broken, thereby allowing massage formulation to flow through the aperture. Accordingly, due to the elasticity of the support means, when an external force is applied to the curved member (for example on the subject's body), it is forced back towards the reservoir, thereby breaking the seal.

In use, the operator pushes the curved member against the affected part of the subject's body and moves it back and forth, or in a circular motion, and this action pushes the curved member backwards, thereby breaking the seal between the aperture and the curved member, and allowing some of the massage formulation to be transferred from the reservoir on to the surface of the curved member, which rotates thereby delivering formulation onto the skin of the subject.

Alternatively or additionally, the therapeutic massage device comprises a control mechanism, which is configured to regulate the amount of the therapeutic massage formulation which is released from the reservoir. The control mechanism may comprise first and second barriers disposed between the reservoir and the delivery means, the barriers being configured for respective rotational movement and each comprising an aperture extending therethrough, wherein alignment of the apertures allows massage formulation to flow therethrough.

In one embodiment, the first barrier is configured to rotate with respect to the second barrier which is fixed, or vice versa. In another embodiment, the first and second barriers are both configured to rotate with respect to each other.

Preferably, the first barrier comprises a plurality of spaced apart apertures extending therethrough. Preferably, the apertures are spaced apart and disposed around the circumference of the barrier. Preferably, the barrier comprises at least two, three or four apertures. Preferably, the diameters of each aperture are different. Accordingly, the barrier may comprise a small aperture (i-2mm diameter), and a larger aperture (5- 10mm). Preferably, the barrier further comprises a medium sized aperture (2-smm).

Preferably, the second barrier comprises one aperture extending therethrough.

Preferably, the aperture in the second barrier is disposed towards the circumference of the barrier at a position which corresponds to the position of the or each aperture in the first barrier. Preferably, the diameter of the aperture in the second barrier is at least the same size or preferably larger than the diameter of the largest aperture in the first barrier. Preferably, the or each aperture in the first barrier is arranged such that respective rotational movement between the barriers enables alignment of the or each aperture in the first barrier with the or each aperture in the second barrier to allow massage formulation to flow therethrough (i.e. an open configuration), or with a section of either barrier which does not comprise an aperture, such that massage formulation cannot flow therethrough (i.e. a closed configuration). Advantageously, a user may select how the barriers (and apertures) align which will control the amount of massage formulation which can be released from the reservoir. Hence, when the aperture in the second barrier is aligned with the large aperture in the first barrier, a large amount of massage formulation may flow from the reservoir.

However, when the aperture in the second barrier is aligned with the section of the first barrier which does not comprise an aperture, then no formulation may flow from the reservoir, and so on.

It will be readily understood that the same effect could be achieved in embodiments where the plurality of apertures is provided in the second barrier. Preferably, the control mechanism comprises a seal disposed between the first barrier and second barrier. The seal may comprise a ring washer. The seal may comprise rubber.

In one embodiment, the first barrier may comprise one or more levers or studs, wherein in use the operator may rotate the first barrier by altering the position of the one or more levers or studs.

In an alternative embodiment, the first barrier may be fixed relative to the delivery means. Accordingly, in use a user may rotate the first barrier by rotating the delivery means relative to the reservoir.

Preferably, one or more markers are disposed on the side of the therapeutic massage device indicating the relative positions of the first and second barriers, e.g. open (high or low flow rate) or closed.

In an alternative embodiment, the support means comprises a first portion defining the aperture through which the curved member extends, and a second portion comprising the collar and one or more struts. Preferably, the second portion is configured to move between a first position in which it causes the curved member to abut the aperture to create a seal which prevents massage formulation from passing therethrough, and a second position in which it allows the curved member to be spaced apart from the aperture thereby breaking the seal, such that massage formulation can pass

therethrough. Preferably, when in the second position the second portion is disposed at a greater distance from the aperture than when it is in the first position. Preferably, a portion of the support means comprises an elastic material (such as rubber, elastomer or TPE), wherein the portion is adjacent to and defines the aperture, such that when the curved member is in the first position, the seal is created due to the contact between the curved member and the portion. Optionally, a portion of the support is over-moulded with a thermoplastic elastomer (TPE). Preferably, the first portion comprises at least one runner configured to engage the second portion. Preferably, the at least one runner extends in an axial direction in relation to the therapeutic massage device. Preferably, the runner is configured to allow the second portion to move axially in relation to the first portion. Preferably, the runner is configured to prevent the second portion from rotational movement in relation to the first portion.

Preferably, the delivery means comprises a further portion configured to support the second portion. Preferably, one of the further portion and the second portion comprises a male member with a screw thread disposed on an outer surface thereof and the other of the further portion and the second portion comprises a female member with a screw thread disposed on an inner surface thereof and configured to receive the male member. The further portion may comprise the female member and the first portion may comprise the male member. However, preferably the further portion comprises the male member and the first portion comprises the female member.

Preferably, the delivery means is configured such that rotational movement of the further portion relative to the second portion causes the second portion to move in an axial direction relative to the first portion.

Advantageously, a user can rotate the further portion which results in screwing or unscrewing of the male and female members, thereby causing the curved member to abut the aperture and prevent the release of the massage formulation. When a user wishes to use the device to release the massage formulation they may rotate the further portion, thereby causing the second portion to be moved further away from the aperture and allowing the curved member to be spaced apart from the aperture and allowing the release of formulation. Advantageously, by rotating the further portion, and thereby selecting the position of the second portion, the user may control the rate of flow of the massage formulation.

Preferably, the device comprises one or more gripping surfaces disposed on an external surface of the reservoir by which an operator can grip the device. The or each gripping surface may comprise a material, which increases friction with the operator's hand/flngers, such as rubber. Preferably, the or each gripping surface is releasably secured to the surface of the reservoir. Advantageously, this will allow a user to use the side of the tool for myofascial massage. Preferably, the external surface of the reservoir comprises a portion which does not have a gripping surface disposed thereon. Preferably, the portion comprises at least 25% of the area of the external surface of the reservoir. More preferably, the portion comprises at least 30%, 40%, 50 or 60% of the area of the external surface of the reservoir. Most preferably, the portion comprises at least 75% of the area of the external surface of the reservoir. Advantageously, the portion can be used to apply pressure close to or on an area suffering from musculoskeletal pain or tension.

Preferably, the device comprises one or more gripping surfaces disposed on an external surface of the delivery means by which an operator can grip the device. Preferably, the external surface of the delivery means comprises a portion which does not have a gripping surface disposed thereon. Preferably, the portion comprises at least 25% of the area of the external surface of the delivery means. More preferably, the portion comprises at least 30%, 40%, 50 or 60% of the area of the external surface of the delivery means. Most preferably, the portion comprises at least 75% of the area of the external surface of the delivery means. Advantageously, the portion can be used to apply pressure close to or on an area suffering from musculoskeletal pain or tension.

Preferably, the supporting means comprises one or more gripping surfaces disposed on an external surface of the supporting means by which an operator can grip the device. Preferably, the external surface of the supporting means comprises a portion which does not have a gripping surface disposed thereon. Preferably, the portion comprises at least 25% of the area of the external surface of the supporting means. More preferably, the portion comprises at least 30%, 40%, 50 or 60% of the area of the external surface of the supporting means. Most preferably, the portion comprises at least 75% of the area of the external surface of the supporting means. Advantageously, the portion can be used to apply pressure close to or on an area suffering from musculoskeletal pain or tension.

Preferably, the further portion comprises one or more gripping surfaces disposed on an external surface of the further portion by which an operator can grip the device. The or each gripping surface may comprise a material, which increases friction with the operator's hand/fingers, such as rubber. Preferably, the or each gripping surface is releasably secured to the surface of the reservoir. Advantageously, this will allow a user to grip different sections of the device enabling them to easily rotate the further portion relative to the supporting means or enabling them to take the device apart for cleaning or filing the reservoir.

It will be appreciated that on some occasions, the operator may wish to use the device without initially releasing any massage formulation onto the subject's body. Preferably, the device comprises a body which houses the reservoir, and a removable cap releasably secured to the body. Preferably, the body comprises the delivery means. Preferably, the body and/or cap comprises a rounded shape making them suitable for use to apply pressure close to or on an area suffering from musculoskeletal pain or tension.

Preferably, the rounded shape comprises a first end of the body or a second end of the cap. Preferably, the first end of the body does not comprise a gripping surface.

Preferably, the second end of the cap does not comprise a gripping surface.

Preferably, the reservoir comprises a bulbous shape making it suitable for use to apply pressure close to or on an area suffering from musculoskeletal pain or tension.

Preferably, the support means comprises a bulbous shape roughly corresponding to the shape of the reservoir. Preferably, the reservoir and the support means are connected by a narrow portion. Preferably, the narrow portion comprises the further portion.

Advantageously, the two adjacent bulbous portions, provided by the reservoir and the support means, allow the device to be used to provide pressure in two places on the body simultaneously. This could be useful for back or spinal therapy where the device could provide pressure either side of the spine simultaneously while it is rolled down a person's back, without putting pressure on the spine. The reservoir and the support means may each be configured to receive an enlarging portion. The enlarging portions may be configured to increase the size of the bulbous reservoir and the support means, without affecting the size of the narrow portion.

Advantageously, this enhances the affect where the pressure is applied at two different points simultaneously. In one embodiment, to prevent the operator from getting massage cream on his or her hands while using the device, the user can use the device with the cap fitted over the curved member. Accordingly, the cap may be sized to leave the gripping surfaces on the reservoir exposed. Alternatively, or additionally, the cap may comprise one or more gripping surface. The or each gripping surface may comprise a material, which increases friction with the operator's hand/fingers, such as rubber. Preferably, the or each gripping surface is releasably secured to the surface of the cap. Advantageously, this will allow a user to use the cap for myofascial massage. Preferably, the external surface of the cap comprises a portion which does not have a gripping surface disposed thereon. Preferably, the portion comprises at least 25% of the area of the external surface of the cap. More preferably, the portion comprises at least 30%, 40%, 50 or 60% of the area of the external surface of the cap. Most preferably, the portion comprises at least 75% of the area of the external surface of the cap. Advantageously, the portion can be used to apply pressure close to or on an area suffering from musculoskeletal pain or tension.

The cap may comprise two or more ribs disposed on an outer surface thereof. The two or more ribs may extend in an axial direction in relation to the therapeutic massage device. The two or more ribs are preferably sized and disposed to allow the cap to rest thereon when placed on a flat surface.

Advantageously, the two or more ribs prevent the cap, which may contain the body, from rolling when placed on a flat surface.

It will be appreciated that a vet or physiotherapist or other similar professionals would learn and understand how to use the device. However, if an untrained person wished to treat themselves or another person, they may not know how to use the device correctly, and there is a risk that using the device incorrectly could result in the user worsening the injury. Accordingly, the device of the first aspect can be used in conjunction with an electrical apparatus comprising a display screen, such as a computer, smart phone or tablet, capable of running an app, which teaches the operator how to use the device.

Preferably, therefore, the device comprises an electronic apparatus configured to display appropriate instructions when prompted to do so by a user. Advantageously, the electronic apparatus allows an untrained person to treat themselves or another person with the massage device of the first aspect. Preferably, the electronic apparatus comprises a computer, an electronic tablet or a smart phone. Preferably, the electronic apparatus is configured to display at least one depiction of a human body, wherein a user may select a part of the body on which he or she wishes to use the massage device.

In one embodiment, the electronic apparatus is configured to display at least one image illustrating how the massage device may be used on the selected part of the body. In an alternative embodiment, the electronic apparatus is configured to display an animation or film illustrating how the massage device may be used on the selected part of the body.

Preferably, the electronic apparatus is configured to display written instructions explaining how the massage device may be used on the selected part of the body.

Preferably, the electronic apparatus is configured to play audible instructions explaining how the massage device may be used on the selected part of the body.

It will be appreciated that the apparatus of the first aspect may be used to treat an injured person. Accordingly, in accordance with the second aspect, there is provided the massage device of the first aspect, for use in treating a subject suffering from a musculoskeletal pain.

In accordance with the third aspect, there is provided a method of massaging a subject, the method comprising contacting a treatment site of a subject's body with the massage device of the first aspect, and applying pressure thereto, to thereby massage the treatment site.

The device of the first aspect and method of the third aspect maybe used in a physiotherapy application or to treat back pain. Alternatively, the device may be used to help improve venous recovery. The device may be used in the beauty and leisure industry to provide an enjoyable massage.

The method of the third aspect can be effectively used to provide therapeutic treatment of the treatment site, which may be causing musculoskeletal pain. As such, in a fourth aspect of the invention, there is provided a method of treating a subject suffering from a musculoskeletal pain, the method comprising contacting a treatment site of a subject's body causing musculoskeletal pain with the massage device of the first aspect, and applying pressure thereto, to thereby massage and treat the pain.

The method preferably comprises initially identifying an injured muscle, wherein the injured muscle is causing the musculoskeletal pain. Preferably, a therapist will locate the site of pain or discomfort using palpatory skills prior to using the tool. The user of the device may be the subject suffering from the musculoskeletal pain. Alternatively, the user may be a different person to the subject suffering from the musculoskeletal pain.

The step of massaging the injured muscle may comprise using the massage device to apply a pressure to the injured muscle.

The pressure may be applied to the treatment site by pressing the rounded shape of the body or cap against the skin covering the injured muscle. Alternatively, the skin covering the injured muscle maybe covered with a towel and the rounded shape of the body or cap may be oushed against the towel, thereby applying the pressure to the treatment site. Preferably, the step of pushing the rounded shape against the skin comprises applying an appropriate sustained pressure along and across an affected area of the injured muscle, wherein the sustained pressure is within the pain limits of the person suffering from the musculoskeletal pain. Preferably, the pressure is sustained for at least 10 seconds. Preferably, the pressure is sustained for or up to a maximum of ninety seconds.

Alternatively, the method preferably comprises massaging the treatment site with the massage device, such that the massage formulation is released onto the treatment site.

Preferably, the pressure is applied to the treatment site by pressing the curved member against the skin covering the injured muscle. Preferably, the massage device is then moved back and forth or in a circular motion across an affected area of the injured muscle while maintaining the pressure exerted by the circular member on the skin of the person, preferably causing the curved member to roll over the skin of the person. Preferably, the pressure exerted on the curved member causes the curved member to move from the first position towards the second position, thereby releasing formulation from the reservoir. Preferably, the distance the curved member moves towards the second position is dependant upon the magnitude of the pressure applied to the injured muscle by the curved member. Preferably, the massage formulation is released onto the skin of the subject. Preferably, the rate at which the massage formulation is released is dependent upon the distance the curved member has moved towards the second position. Preferably, the rate at which the massage formulation is released is dependent upon the speed at which the massage device is moved back and forth or in a circular motion.

In a preferred embodiment, prior to pressing the curved member against the skin, the method comprises removing the cap from the massage device.

The step of identifying an injured muscle may comprise inputting sufficient data into electronic apparatus to allow the electronic apparatus to identify the injured muscle.

The step of identifying an injured muscle may comprise the initial step of prompting the electronic apparatus to display at least one depiction of a human body. The step of prompting the electronic apparatus may comprise opening a program stored on the electronic apparatus. Optionally, the step of prompting the electronic apparatus may also comprise inputting the gender of the subject, preferably causing the electronic apparatus to display at least one depiction of a human body of the selected gender. However, in a preferred embodiment the treatment rationale renders the distinction between genders unnecessary.

Preferably, the step of identifying an injured muscle comprises selecting a part of the body on the at least one depiction of the human body, wherein the selected part of the body corresponds to a body part where the subject is suffering from the

musculoskeletal pain.

Preferably, selecting the part of the body causes the electronic apparatus to display at least one image, animation or film illustrating how the massage device may be used on the selected part of the body. Preferably, selecting the part of the body causes the electronic apparatus to display written instructions explaining how the massage device may be used on the selected part of the body. Preferably, selecting the part of the body causes the electronic apparatus to play audible instructions explaining how the massage device may be used on the selected part of the body.

Example 1 - Therapeutic massage device

A therapeutic massage device 1 is illustrated in Figures 1 to 4, and has been developed to enable physiotherapists or other similar professions, to better treat a patient suffering from musculoskeletal pain, and also to allow patients to treat themselves or be treated by an untrained person (subject to learning the correct method for using the device), such as a friend or family member.

The device 1 can be used to treat a person who is suffering from muscle fibers having areas of microspasm. Essentially this is where knots and adhesions form in the muscle which prevent the muscle from contracting properly thus affecting the length tension relationship of the muscle. In a worst case scenario, without treatment, the afflicted person may move differently to compensate, which could result in further injuries. Traditionally, a person suffering from such an injury would have to visit a

physiotherapist who would apply a "myofascial release" or "trigger points" massage to the affected area. Normally, the physiotherapist would use their thumbs to massage the affected area, but this can result in the physiotherapist suffering from repetitive strain injury in their thumbs which could ultimately end their career.

The therapeutic massage device 1 includes a body 2 and a cap 3, which can be separated from each other manually by a user and are shown separately in Figures 2 and 3, respectively. The body 2 and cap 3 comprise injection moulded plastics such as - ι ₅ - polypropylene. The cap 3 fits over one end of the body 2 as shown in Figure 1. In one embodiment, the cap 3 and body 2 are provided with corresponding screw threads enabling the cap 3 to be screwed onto the body 2 and holding the cap 3 in place.

Alternatively, the cap 3 may be held in place on the body 2 due to corresponding projections provided on the body 2 and cap 3, or a projection provided in the body 2 and a corresponding indentation provided in the cap 3, or vice versa, or simply a friction fit.

In the embodiment illustrated, a first end 4 of the body 2 includes a reservoir 6, whereas a second opposing end 5 of the body 2 includes a roller 7. The reservoir 6 and roller 7 are shown separately in Figure 4 for clarity, but in use the body 2 is a single unit as shown in Figure 2. The reservoir 6 is configured to contain a massage formulation 8, for example an oil-based liquid or gel, such as Deep Heat® heat rub or Deep Freeze® cold gel. The massage formulation 8 can also include an emulsion, preferably a body lotion.

The roller 7 is reversibly removable from the reservoir 6 allowing a user to replenish the massage formulation 8 when empty. This can be achieved by providing corresponding screw threads in the reservoir 6 and the roller 7. Alternatively, the roller 7 and reservoir 6 may be sealed together.

The reservoir 6 is sized to fit comfortably in the hand of a user and to allow the user to grasp the reservoir 6. Accordingly, a user will be able to hold the reservoir 6 between their thumb and index fingers, or all of the fingers and/ or palm of the hand thus, allowing the user to exercise a degree of control when using the therapeutic massage device 1, or grasp the reservoir portion 6 in the palm of their hand, allowing the user to apply a firm pressure when using the therapeutic massage device 1. To allow a user to better grip the reservoir 6, the external surface 9 of the reservoir 6 has a material, such as rubber, which increases friction with the user's hand/fingers. Grips 10 are also provided on the external surface 9 of the reservoir portion 6, these grips 10 may comprise rubber, or a similar material.

Referring to Figure 2, the roller portion 7 of the device 1 comprises a casing 11 having an aperture 12 disposed adjacent to the second end 5 of the body 2. The size and shape of the aperture 12 corresponds to a cross-section of a roller ball 13, which may also comprise injection molded plastics such as polypropylene. When the device 1 is assembled, the roller ball 13 is disposed adjacent to the aperture 12 such that one portion 14 of the ball 13 is disposed within the body 2 in communication with the reservoir 6, and the opposite portion 15 of the ball 13 extends through aperture 12. Ideally, the volume of the portion 14 held in the body 2 is greater than the volume of the portion 15 which protrudes through the aperture 12 out of the body 2. The use of this then facilitates an effective 'controllable' rolling sensation on the skin irrespective of the size or body composition of the person treated.

The casing 11 is configured to restrict the translational degrees of freedom of the roller ball 13 relative to the casing 11 while still allowing the ball 13 to rotate. The Figures illustrate the roller ball 13 as a sphere possessing full rotational freedom around 360 °, but in other embodiments, it can be cylindrical or ovoid in shape, in which case it would possess one degree of rotational freedom relative to the casing 11 when disposed therein.

As shown in Figure 4, the casing 11 includes an internal supporting structure 17 consisting of three struts 18 which support the roller ball 13 within the body 2 while still allowing it to rotate. It will be appreciated that different supporting structures 17 could be used. The supporting structure 17 possesses a degree of elasticity such that it exerts a force on the roller ball 13 to thereby restrict its movement in a first direction 19, as shown in Figure 2. Accordingly, when no pressure is applied to the roller ball 13 by an operator, the force exerted by the supporting structure 17 urges the roller ball 13 to remain flush against the aperture 12, thereby effectively sealing the aperture 12, such that no cream 8 leaks out of the reservoir 6. Hence, due to the seal created between the roller ball 13 and aperture 12, the massage formulation 8 stored in the reservoir 6 does not leak from the therapeutic massage device 1 when it is not being used.

However, due to the elasticity of the supporting structure 17, when an external force is applied to the roller ball 13 by an operator in the first direction 19, the ball 13 is forced slightly back into the body 2 of the device 1, thereby breaking the seal. Thus, when a user uses the device 1, they push the roller ball 13 against the affected part of the body and move it either back and forth or in a circular motion. This action pushes the roller ball 13 back into the body 2 of the device 1, thereby breaking the seal and allowing some of the massage formulation 8 to be transferred from the reservoir 6 onto the surface of the ball 13 and eventually onto the skin of the target site. It will be understood that, up to a predetermined maximum, the more pressure applied by the operator to the device 1, the further the roller ball 13 will move into the body 2, resulting in more massage formulation 8 being transferred out of the reservoir 6 and onto the target site. The movement of the device 1 will also cause the roller ball 13 to rotate within the casing 9. When the operator stops using the device 1, then no external pressure is applied to the roller ball 13, and so the force exerted by the supporting structure 17 causes the ball 13 to move in a second direction 20, as shown in Figure 2, until the ball 13 is flush against the aperture 12 reforming the seal. Alternatively, or additionally, a control mechanism 34 is shown in exploded view in

Figure 10. The control mechanism 34 comprises a first barrier 36 and a second barrier 38 disposed between the reservoir 6 and roller 7. The second barrier 38 is fixed relative to the reservoir 6, and may be screwed thereto, but the first barrier 36 may rotate relative to the reservoir 6. The first barrier 36 may be connected to the second barrier 38 due to the presence of an axle (not shown) passing through the centre of the first and second barriers 36, 38. Additionally, the first barrier may be screwed to the roller portion 7. A user may cause the first barrier to rotate by moving a stud 40 provided on the side of the first barrier 36, or by rotating the roller portion 7. In the example illustrated in Figure 10, a small aperture 42, medium aperture 44 and large aperture 46 are spaced apart and extend through the second barrier 38. However, it will be understood that in practice the second barrier could be provided with any number of spaced apart apertures. Additionally, a further aperture 48 which is substantially the same size as the large aperture 46 is provided in the first barrier 36.

By rotating the first barrier 36 a user can align the further aperture 48 with the small aperture 42, medium aperture 44, large aperture 46, or with a section 50 of the second barrier 38 which does not comprise an aperture. Accordingly, when the further aperture 48 is aligned with the section 50 of the second barrier 38 which does not comprise an aperture no massage formulation may pass from the reservoir 6 to the roller 7. But when the further aperture 48 is aligned with the small aperture 42, medium aperture 44 or large aperture 46 the flow of formulation from the reservoir 6 will be controlled by the size of the aperture in the second barrier 38. A user may select how the apertures are aligned by aligning the stud 40 with markers 52 provided on the side of the device 1, which marks reflect the aperture size. A seal is provided between the first and second barriers 36, 38 to prevent the formulation from leaking from the reservoir.

It will be appreciated that on some occasions, a user may wish to use the device 1 without releasing any cream 8 onto the body being treated. Accordingly, the first end 4 of the device 1 is shaped in a rounded point making it suitable for use to apply pressure on an area suffering from musculoskeletal pain.

To prevent a user from getting the cream 8 on their hands while using the first end 4 to massage the afflicted area, the user would use the device 1 with the cap 3 fitted over the roller ball 13. Accordingly, the cap 3 is sized to leave the grips 10 on the reservoir portion 6 exposed. Alternatively, as shown in Figure 1, additional grips 23 are provided on the cap 3. The device 1 can be used to massage a person through their clothes or through a towel without running the risk of transferring the therapeutic massage lotion 8 onto these garments.

Example 2 - Electronic app

A physiotherapist would understand how to use the device 1 and would not need any further input. Accordingly, a physiotherapist could use the device 1 instead of their thumbs and avoid the risk of developing repetitive strain injury. However, if an untrained person wished to treat themselves or another person (such as a friend or their spouse), they may not know how to use the device 1 correctly. There is even a risk that using the device 1 incorrectly could result in the user worsening the injury.

Additionally, it is possible that even a physiotherapist may be unsure of the best practice for using the device.

Accordingly, the device 1 can be used together with an electrical device comprising a display screen, such as a computer, smart phone or tablet, capable of running an app. When the device 1 is sold to the user, the packaging includes a 2D barcode, such as a QR barcode, which when scanned gives the user the option of downloading the app onto an electronic apparatus. A user wishing to use the device 1 on themselves opens the app on the device, and this results in the app displaying different views of the human body 24 which the user can scroll through. As seen in Figures 5 to 7, these views may comprise a rear view 25, a front view 26 and/ or a side view 27 of the body 24. While only a right side view 27 is shown in Figure 7, it will be appreciated that in practice both a right side view 27 and a left side view (not illustrated) could be displayed. The human body 24 shown can be gender neutral, as depicted. Alternatively, on opening the app, the user may be asked to specify their gender. Once this information is input the app will then display various views, similar to those illustrated in Figures 5 to 7, but of either a male or female body, as appropriate.

The user then clicks on the area of the body which is troubling them. For instance, if the user had a pain in their quadriceps 28, then they would click on the top half of the leg 29 in the front view 26, as shown in Figure 6. The user then has to answer further questions to allow the device to ascertain the exact injury the user is suffering from.

Once the device has determined the injury, the app causes the device to display a close- up of the afflicted area 30 as shown in Figure 8. In this case the injury comprises fascial adhesions 31 which are affecting a muscle fibre 32 in the user's quadriceps 28. Accordingly, the device displays an image of the upper front portion of a leg 29 including the quadriceps 28, as shown in Figure 8. The display also shows the user's injury schematically, and this is better illustrated in Figure 9 which is a close-up of the image of Figure 8 and shows the fascial adhesions 31 represented along the affected muscle fibre 32. The app then causes the device to display a series of pictures or an animation illustrating how the device 1 should be used to treat the afflicted area. The pictures or animation are accompanied by suitable instructions, and these could be in the form of written instructions or an audible commentary, explaining how the device 1 should be used. For example, in this case, the user would be instructed to use the first end 4 of the device 1 to apply appropriate sustained pressure along and across the length of the affected area on the muscle with a thin cloth acting as a medium between the first end 4 and the skin to reduce viscosity and facilitate an effective myofascial treatment. The sustained pressure should be within the pain limits of the patient and will normally last up to ninety seconds to release the microspasm by breaking up the fascial adhesions 31.

To prevent a user from injuring themselves further, on initially opening the app, a warning may flash up alerting the user to when and where the device 1 should not be used. For instance, on bony areas, on hypersensitive skin, on areas of varicosity or in the acute phase of the injury - typically the first 48 to 72 hours period immediately after the injury has been sustained. Example 3 - Alternative therapeutic massage device

Alternative embodiments of the therapeutic massage device are shown in Figures 11 to 19. A therapeutic massage device 100 shown in Figures 12 to 19 has a body 102. Similar to the device 1 described in Example 1, the body 102 has a first end 104 which includes a reservoir 106 and second end 105 which includes a roller portion 107. In this embodiment, the reservoir 106 and roller portion 107 are interconnected by a central collar 160.

The reservoir 106 is bulbous in shape and is sized to fit comfortably in the hand of a user and to allow the user to grasp the reservoir 106. As with the device 1 described in Example 1, a user will be able to hold the reservoir 106 between their thumb and index fingers, or all of the fingers and/or palm of the hand thus, allowing the user to exercise a degree of control when using the therapeutic massage device 100, or grasp the reservoir portion 106 in the palm of their hand, allowing the user to apply a firm pressure when using the therapeutic massage device 100.

An indentation 162 provided around the circumference of the reservoir 106 at its widest point corresponds to a projection 164 (best seen in Figure 19) extending around the circumference of the internal surface of a cap 103. This allows the cap 103 to be removable fitted over the body 102, as shown in Figure 13, due to the bump fit provided by the corresponding indentation 162 and projection 104. Referring to Figure 13, cap 103 has two spaced apart ribs 121 which run parallel to each other and in the axial direction and are configured to allow the cap 103, containing the body 102, to be rested on its side without rolling.

As can be seen in Figure 19, the reservoir 106 narrows to form a neck 165 which ends in a lip 167. The neck 165 comprises a screw thread 166 disposed on an external surface of the neck 165. Additionally, an indentation 168 around the circumference of the neck 165 is disposed between the screw thread 166 and the lip 167. When the device 100 is being assembled, a lower body o-ring 170 can be fitted over the neck 165 of the reservoir 106, and located in the indentation 168. The central collar 160 can then be screwed to the reservoir 106 due to a screw thread 171 being provided on an internal surface of the central collar 160, adjacent to a first end 173. The o-ring 170 ensures that any massage formulation held in the reservoir 106 will not leak from the join between the reservoir 106 and the central collar 160. Since the reservoir 106 is reversibly removable from the central collar 160, it allows a user access to the reservoir 106 to clean the device or replenish the massage formulation when desired.

As can be seen in Figure 12, the roller portion 107 has a bulbous shape which is similar to that of the reservoir 106. Accordingly, when fully assembled, the body 102 has a figure of eight shaped cross-section, where the narrowest portion is defined by the central collar 160.

The roller portion 107 of the device 100 is shown in Figure 15, and comprises a casing

111, which comprises an upper portion 172 and a lower portion 174. The upper portion 172 defines an aperture 112 provided in its second end 176. The size and shape of the aperture 112 corresponds to a cross-section of a roller ball 113. When the device 100 is assembled, the roller ball 113 is disposed adjacent to the aperture 112 such that one portion 114 of the ball 113 is disposed within the body 102 in communication with the reservoir 106, and the remaining portion 115 of the ball 113 extends through aperture

112, this is best shown in Figure 16. Ideally, the volume of the portion 114 held in the body 102 is greater than the volume of the portion 115 which protrudes through the aperture 112 out of the body 102. The use of this then facilitates an effective

'controllable' rolling sensation on the skin irrespective of the size or body composition of the person being treated.

As seen in Figure 15, the upper portion 176 comprises a neck 180 adjacent the first end 178 thereof. The neck 180 comprises an indent 182 around the circumference thereof configured to receive an upper body o-ring 184.

First and second parallel projections 186, 187 are provided, which extend round the circumference of the inner surface of the lower portion 174 adjacent to the first end 188. Similarly, two parallel projections (not shown) which extend round the circumference of the inner surface of the lower portion 174 adjacent the second end 190 are also provided.

When the roller portion 107 is assembled the roller ball 113 will be placed in the lower portion 174 and the upper body o-ring 184 will be placed over the neck 180 and in the indent 182. The neck 180 can then be pushed into the second end 190 of the lower portion 174. The o-ring 184 will be pushed over the first projection and will be held in place between the two projections. As well as holding the upper and lower portions 172, 174 together, the o-ring 184 prevents leakage from the join between the two parts. The casing 111 and central collar 160, together with a ball support 191, are configured to restrict the translational degrees of freedom of the roller ball 113 relative to the casing 111 while still allowing the ball 113 to rotate.

As can be seen in Figure 17, a neck 192 is disposed adjacent to the second end 194 of the central collar 160. The neck 192 comprises an indentation 196 sized to receive a central collar o-ring 198. Referring now to Figure 18, the central collar 160 comprises an internal central support 200 which is formed integrally with the collar 160. The central support 200 comprises three struts 202, spaced apart from the second end 194, which support a solid projection 204 which extends in an axial direction towards the second end and is provided with a screw thread on an external surface thereof.

The ball support 191 comprises a circular lip 206 which extends outwardly from an outer skirt 208. The diameter of the circular lip 206 is roughly equal to the diameter of the neck 192 provided in the second end 194 of the central collar 160. Similarly, the outer skirt 208 is sized to fit inside the central collar 106. Three struts 210 extend inwardly from the outer skirt 208 and support an inner skirt 212. The inner skirt 212 comprises an internal screw thread and is sized to mate with the projection 204 of the central support 200. Three indentations 214 in the circular lip 206 correspond to three runners (not shown) provided on the internal surface of the lower portion 174. The three runners extend from an area substantially adjacent to the second projection 187 in an axial direction towards the second end 190 of the lower portion 174.

When the casing 111, ball support 191 and central collar 160 are assembled, the o-ring 198 will be placed over the neck 192 in the indent 196. The inner skirt 190 of the ball support 191 is then screwed over the projection 190 until the circular lip 206 is substantially flush with the second end 194 of the central collar 160. The second end 194 of the central collar 160, together with the attached ball support 191, can then be pushed into the first end 188 of the lower portion 174, ensuring that the indentations 214 in the circular lip are aligned with the three runners. The o-ring 198 will be pushed over the first projection 186, which is closer to the first end 188, and held in place between the two projections 186, 187. As well as holding the lower portion 174 and the central collar 160 together the o-ring 196 prevents leakage from the join between the two parts. It will be appreciated that while this join prevents the central collar 160 from moving in an axial direction relative to the lower portion 174, the central collar 160 may rotate independently of the lower portion 174.

When the lower portion 174 and the central collar 160 are held together, as described above, the indentations 214 in the circular lip 206 of the ball support 191 will receive the runners therein. Accordingly, this will prevent the ball support 191 from rotating independently of the lower portion 174. Accordingly, rotating the central collar 160 independently of the lower portion 174 will cause the ball support 191 to move up or down in an axial direction relative to the central portion 160, due to the relative movement of the corresponding screw threads provided on the inner skirt 212 and the projection 204. When the central collar 160 is rotated to a fully clockwise position it will push the ball 113 against the aperture 112 creating a seal and thereby prevent any massage formulation from flowing out of the aperture 112. However, when a user wishes to use the device 100, they can rotate the central collar 160 anticlockwise. This will lower the ball support 191 and allow the ball 113 to be displaced slightly from the aperture when axial pressure is applied to the roller ball 113. Accordingly, when a user uses the device 100, they push the roller ball 113 against the affected part of the body and move it either back and forth or in a circular motion. This action pushes the roller ball 113 back into the casing 111, thereby breaking the seal and allowing some of the massage formulation to be transferred from the reservoir 106 onto the surface of the ball 113 and eventually onto the skin of the target site as the ball 113 rolls. It will be appreciated that by varying the position of the ball support 191, it will be possible to control how far into the casing 111 the ball 113 can be displaced, and will thereby affect how much formulation can be transferred as the ball 113 rotates. When a user has finished with the device, or no longer wants it to dispense the massage formulation, they may then rotate the central collar 160 fully clockwise to reform the seal caused by the ball 113 being pressed against the aperture 112.

To aid a user in gripping the body 102 and cap 103, either during use or assembly and disassembly of the device 100, grips 110 are provided on the external surface of the reservoir portion 106, the lower portion 174 of the casing 111, the roller portion 107 and the cap 103, these grips 110 comprise rubber. The rest of the body 102 and the cap 103 can be made from polypropylene, polycarbonate or poly(methyl methacrylate), optionally with a thermoplastic elastomer (TPE) over-mould. Alternatively, the central collar 160 can be made from a metal such as aluminium. The o-rings 170, 184, 198 would be made from rubber.

Additionally, as shown in Figure 12, the upper portion 172 of the casing 111 comprises a plurality of oval indentations 216 for the user to grip. Alternatively, in the embodiment illustrated in Figure 11, the upper portion 172 of the casing 111 comprises a groove 218 for the user to grip.

If the user wants to use the device 100 to massage themselves without dispensing massage formulation then they can use the first end 104 of the device to apply pressure in the desired location. This could be done while the cap 103 remains in place over the body. It will be appreciated that the user will not want to massage themselves with a portion of the device which comprises a grip 110. Accordingly, the first end 104 does not comprise a grip.

Alternatively, or additionally, the user can remove the cap 103 and use the sides of the device 100 to apply pressure in the desired location. Due to the figure of eight shaped cross-section this method will simultaneously provide pressure at two points. For instance, this could be useful for back or spinal therapy where the device could provide pressure either side of the spine simultaneously while it is moved down a person's back, without putting pressure on the spine. Again, it will be appreciated that the user will not want to massage themselves with a portion of the device which comprises a grip

110. Accordingly, the grips 110 provided on the sides of the reservoir 106 and the roller portion 107 only cover a small portion of the external surface, as shown in Figures 11 and 12. Alternatively, or additionally, the ability to use the reservoir 106 and roller portion 107 to provide pressure at two points simultaneously could be enhanced by fitting enlarging portions (not illustrated) over each of the bulbous ends. The enlarging portions could be made of a polymer or rubber. Summary Advantageously, the devices described in Examples 1 and 2 allow a physiotherapist, or other similar therapists mentioned, to treat a patient whilst mitigating the risk of injury to themselves through repetitive strain of their thumbs. Additionally, an unskilled person is able to treat him or herself or another person as per the instructions in the apps and mitigating repetitive strain injury to themselves and without risking making the injury worse.

A further advantage conferred by the devices is the option to choose whether or not a massage formulation is released as the device is used to massage an injury, ant to control the rate at which the formulation is released.

While the above disclosure describes the device being used in a physiotherapy application it may also be used to help treat back pain or used on areas suffering from varicose veins, and thereby aid the venous recovery. Alternatively, it could be used in the beauty and leisure industry to provide an enjoyable massage.
