DESCRIPTION

Field of the Invention

[001] The present invention relates to adjustable therapeutic apparatus for the human torso.

Background of the Invention

[002] In the modern world, most of the day our spine is in the wrong position, which means that all organs and systems of the body are subjected to stress. And physical activity aimed at maintaining the muscles of the back is minimal. All these factors affect the development of osteoporosis and curvatures in the spine. Statistics indicate 80% of people who suffer from back pain during their lifetime. Back pain is not only a medical problem, but also a social and economic one. In terms of the number of days of disability, patients with back pain are among the leaders. If we turn to the risk factors for musculoskeletal pain associated with the working environment, they can be divided into four groups: individual, physical, clinical and psychological. Among the physical factors is a prolonged static position of the back, neck and arm, which leads to muscle spasm in the subscapular region, neck muscles and lower back. Also, they include stereotyping movements, non-compliance with ergometric conditions in the workplace, prolonged sedentary work and uncomfortable posture.

[003] Prevention of diseases of the spine is in constant physical education. Physical exercises strengthen the muscles of the whole body, increase their strength, and also normalize the functions of the body. Also, an integral part of treatment and prevention is medical massage to relax tense areas of the back. An auxiliary tool for the treatment and restoration of the spine are orthopaedic corsets. Hard and semi-rigid. A corset is an auxiliary device that fixes, stabilizes and unloads the spine. This type of orthosis normalizes muscle tone and forms a physiologically correct position of the body, which helps relieve muscle spasm and back pain. Corsets are designed for the treatment and prevention of diseases of the spine.

[004] Most of the existing braces and corsets have mainly the effect of rigidly stabilizing the human torso and providing low back mobility due to rigid materials and a strong girth. This negatively affects blood circulation in the skin and muscles in the corset area, which leads to a decrease in the effectiveness of treatment or, in some cases, to side complications.

[005] The prior art discloses various therapeutic apparatuses. The US patent application publication No. US 4622957 discloses a therapeutic corset which is adapted for the sacrum, lumbar and thoracic region of the body comprises an elongated support surface formed from material that is bendable when subjected to forces encountered thereby. Disposed on the support surface and secured thereto along its edges is a flexible cover disposed thereover to form an envelope. The envelope is provided with a duct of introducing fluid therein and retaining same, thus inflating the envelope causing the surface to bend to assume a predetermined curvature, which is preferably in the shape of a crescent.

[006] The US patent application publication No. US2021/0113359 discloses a spinal orthosis comprising an elongate and substantially rigid spinal frame having upper, middle and lower portions, and a lumbar assembly connected to the lower portion of the spinal frame.

[007] The international application publication No. W02009/052031 discloses an adjustable posterior spinal orthosis comprising a pair of flexible strap members removably attached at the top of the spinal member and secured and anchored at the bottom. Flexible straps form not only the shoulder straps but also contribute an adjustably fastening arrangement of smaller loops with connecting straps to abdominal pads. The abdominal pads can be fastened together and fastening pads can both secure and tighten the brace on the patient by pulling the flexible straps. French patent application publication No. FR3001125 discloses a clothing that has an elastic sheath intended to enclose a part of the trunk of a user, where the sheath includes an outer face and an inner face. An array of wooden balls is fixed at the inner face of the sheath such that array of balls rests directly against the enclosed part of the user when the garment is worn by the user. Each ball includes a central opening for passing ligaments, so as to form a chain of balls and to fix the chain of balls at the inner face of the sheath, where the ligaments are arranged so that the balls are movable in rotation.

Summary of the Invention

[008] The therapeutic apparatus for a human’s torso differs from the prior art in that it can provide not only strengthening of the musculoskeletal system of the back, but also provides a relaxing effect like a medical massage. This is ensured by a combination of technical features of the invention located in anatomically correct places.

[009] The apparatus has an inner side directed to the human’s torso, and outer side directed outside from the human’s torso. The apparatus comprises at least two acupressure elements with 1 mm to 10 cm distance between/from each other, wherein the acupressure elements are made of rigid material and comprising at least one canal therethrough for threading at least one string through the canal. The apparatus comprises at least two strings, which are an elongated elements made of a stretch material. The strings wrap the human’s torso, and thus the strings press the acupressure elements towards the human’s torso. The strings are arranged transversally in relation to the sagittal plane of the human. The apparatus comprises at least two string fasteners. Each of two ends of the string is fastened to the string fastener. One string fastener is attached to another string fastener, so that one string fastener overlaps another string fastener and thus changes the distance between the ends of the strings, and thus changes the tension of the strings. The string fasteners may have hook and loop or hook and eye, or rivet snaps. The apparatus comprises at least two reinforcing elements, which are elongated elements made from elastic and rigid material. Such materials elements are elastic in one direction and rigid in another direction. Typical example could be a plastic filament or rod. The reinforcing elements are arranged transversally in relation to the strings forming web like structure.

[Oi l] The therapeutic apparatus further comprises a back member, which is made of woven material at least from one layer of fabric and covers part of the back and lateral sides of human’ s torso. The back member comprises back member eyelets allowing the strings to be threaded therethrough. The apparatus further comprises at least one strap, which is an elongated element made of elastic material, which are continuation of the back member, extended from the back member in left direction and symmetrically to the sagittal plane the same numbers of straps extended from the back member in the right direction and straps wrap the human’s torso. At each distal end from the back member the strap comprises a strap fastener. The reinforcing elements are associated with the back member so that the back member extends along all length of the reinforcing elements.

[012] The back member may comprise a dividing cloth with dividing cloth eyelets, through which the strings are threaded as follows: the string is threaded from the outer side through the dividing cloth eyelet of the dividing cloth, then threaded through the acupressure element, then threaded through the dividing cloth eyelet of the dividing cloth from the inner side, and then threaded through the dividing cloth eyelet from the outer side of dividing cloth and so on alternates with at least two acupressure elements. In another embodiment the back member may comprise at least two layers of cloth, between which the acupressure elements, the reinforcing elements, the strings and the dividing cloth are positioned.

[013] The apparatus may comprise a back string, where one end of the back string is attached to the back member and another end of the back string is attached to the back string fastener. The apparatus may comprise at least two loops located on the surface of the straps from outer side for threading the strings through it. The strings wrap around the human’s back and are threaded through the loops for comfortable use of the therapeutic apparatus, so that even when the strings are unfastened, the fasteners remain in the part of the torso accessible to the human using the therapeutic apparatus. At least one of the strings or the back strings may have at least two sections with different elasticity, in result of which a different stroke length of the acupressure elements is provided when the strings and/or the back strings are stretched.

[014] The therapeutic apparatus may further comprise at least two attachment points for attachment of the strap fasteners or the string fastener, which are located on the surface of straps or on a surface of the back member symmetrically to the sagittal plane. The strings and back strings that wrap around the human’s torso may be threaded through the loops and, having made a 180-degree bend, are fastened to the attachment point at lateral or rear side of the back member by the string fastener or back string fastener.

[015] In another embodiment of the invention at least one end of the one back string is fixed to the back member in a one place, and the other end of the back string is fixed to the back member in the other place, thus the back strings are stretched with the back member, when the straps are fastened around the human’s torso.

[016] The therapeutic apparatus may further comprise at least two cells for acupressure elements in the back member, formed by stitching together at least two fabric layers of the back member around the acupressure element with the string threaded through the acupressure element. At least two acupressure elements are located inside the cells for acupressure elements, thus the cells for acupressure elements limits the length of dislocation of acupressure element at length equal to acupressure element length, which provides a massage effect when the human moves using the apparatus.

[017] The therapeutic apparatus may further comprise a pair of shoulder straps extending parallel and symmetrically to the sagittal plane from the upper part of the back member, and wrap around the human's shoulders and, using strap fasteners at the ends of the shoulder straps, are attached to the attachment point on the straps. The therapeutic apparatus may further comprise at least two strap lugs, which located on the surface of the strap, and a pair of the shoulder straps extending parallel and symmetrically to the sagittal plane from the upper part of the back member, wrap around the user’s shoulders, are threaded through the strap lugs on the straps and, having made a 180-degree bend, are fastened on the attachment point on the shoulder strap by the strap fasteners on the shoulder straps. A pair of shoulder straps extend parallel and symmetrically to the sagittal plane from the upper part of the back member and wrap around the human's shoulders, and wherein shoulder straps are attached to the straps by the at least one elastic band.

[018] The apparatus relieves tension in the back muscles, increases blood microcirculation and relieves back pain. The brace helps to restore the correct posture by mechanically increasing the curvature of the back waist - for this purpose, the sides of the apparatus have a specially designed tensioning mechanism, which, when tightened, allows to apply the curvature of the back regions that is suitable for different human torsos.

[019] The apparatus adapts to any curvature of the body and even during intense movements, such as sports, the designated technical features of the apparatus fully occupies the required position.

[020] The fabric of the apparatus is selected from the light and breathable materials and at the appropriately chosen tightening intensity, in result of which it will not cause any friction or body imprint.

[021] The apparatus has several sectors of acupressure elements, which are arranged in a certain order in a mirror image relative to the sagittal plane of the human’s torso. The distribution of acupressure elements interacts with the human’s muscular corset thereby stimulates blood flow to the damaged areas of the spinal column. Zones of acupressure elements create a restorative effect. This effect is achieved by the fact that the pressure created by the acupressure elements is a completely new and unusual sensation for the human in the area of torso. The human’s muscular corset is stimulated and activated for rehabilitation removing the load from the spine. [022] The apparatus has embodiments for the Sacro-lumbar, lumbar-thoracic and thoracic spine as interacts with torso lateral parts. The design of the apparatus includes acupressure elements that interact with the strings and are located in special cells that determine the location of the acupressure elements. Strings are located in several levels and can have both horizontal and vertical direction. Reinforcing elements separate the zones in which the acupressure elements are located. The reinforcing elements provide the apparatus shape and prevent the apparatus from bulging while wearing. The inner side of the apparatus fits snugly to the human’s torso. The pressure created by the string conjunction with the acupressure elements does not create pain, and is selected so that it is not weak. Strings, divided into zones, and have adjustable fastening elements on the ends which greatly expands the possibilities of adjusting tension and fastening of the apparatus.

[023] Acupressure elements used in the apparatus can be variable size and form. In another apparatus embodiment different size and form acupressure elements can be used together. Acupressure elements in the different size and shape can be used in the apparatus embodiment which will provide different acupressure effect to the different human’s torso parts. In another embodiment the strings go through the canals in the acupressure elements so the acupressure element can slide on the string. In another embodiment the acupressure elements can be bonded with the strings. The acupressure elements can comprise a threaded hole arranged perpendicular to the canal for a set screw, allowing the set screw to hold the string within the canal thereby holding the acupressure element from sliding along the string. Number of the canals can be as one as many as strings goes through the acupressure element. In another embodiment of the acupressure element and the string combination, attachment of the acupressure element to the string can be done through the acupressure element surface.

[024] Acupressure elements on parallelly located strings can be arranged symmetrically parallel to each other, as well as in other positions. The apparatus is divided into sectors that allow the formation of independent pressure on various elements of the human’s torso. By changing the tension force of the strings, pressure of the acupressure elements to the body also changes. The principle of work of the sectors allows to act on different muscle groups, thereby helping to give the best therapeutic effect.

[025] In various apparatus embodiments one or more strings can be used. Each string can carry one or more acupressure elements. String tension load can be uniform or variable through the all-element body. This provides the possibility to create different tensile load between the acupressure elements. Also, variable and uniform stretching load strings can be used in one apparatus design. Apparatus embodiments enclose strings in different directions like parallel, diagonal or crossing. Independently of placement of the tension elements, they can be attached to the apparatus each separately or bonded together to the one point in the apparatus inside constructions, outer or inner surface. If there is a single point connection of the strings the length of the string element can be different or similar. Pulling of the fastening element of the string in the embodiment of different lengths provides different tension load in the elements and pressure created by the acupressure elements. In the case of spinal correction, strings of various lengths increase the lordosis of the spine and enhance the effect of acupressure on certain parts of the human’s back. Through the length the string it can be formed from non-stretchable elements and elastic or semi elastic regions.

[026] The string fastener can be attached to the attachment point of apparatus or attached with other string fastener.

[027] Strings can be bonded to the back member of the apparatus. The string one point can be fixed to the brace or additional reinforcing element can be placed above. In another embodiment the ends of each string element are not bonded to the apparatus and can be fastened in a free manner. Additional strings can be added as a standalone string laying on the outer or inner surfaces. Strings can be placed in a different direction.

[028] In another embodiment string may consists of different sections and described as polytension element. The string having at least two sections with different elasticity, wherein the acupressure elements are attached to the sections of the strings via the rivet snaps or the setscrews, which provides a different stroke length of the acupressure elements when the strings are stretched. Due to the different tension of the string sections, the elements are pressed differently in the required place of the human’s torso. Also, the amplitude of movement of the elements will be different during the stretching of the string to provide the necessary massage effect.

[029] The acupressure elements and the strings layout can be as inside the back member or on the inner or outer surface with all possible combinations. One of the possible variations: acupressure elements are on the apparatus inner surface allowing direct contact with a skin of human’s torso. The back of the apparatus is wider to maximize the number of acupressure elements. The side parts of back member are narrower to reduce the pressure on the human’s ribs.

[030] In another embodiment the acupressure cells are stitched around the acupressure elements on the back member to retain their position during the use and locate them in the necessary sectors.

[031] The reinforcing elements of the apparatus can be of different widths, lengths and stiffness. In case of injury, reinforcing elements can be used that are not elastic and reliably hold the muscle core of the human’s body, preventing it from deforming. The reinforcing elements of apparatus can be combined with the strings and be as a shape retainer of the apparatus.

[032] Different types of fabric fasteners can be used for apparatus straps and strings, for example, hook and loop, hook and eye, rivet snaps or any other fastening element which allows to secure fastening and is known to the skilled person. The size of the apparatus can vary and fit any human’s torso type according the specification.
