Description:
A holder for a medical device

Technical Field

The invention relates to a holder for a medical device, a kit and a method for mounting a medical device on a skin site of an extremity of a user. The devices and the method according to the present invention may mainly allow adherence of a transcutaneous sensor and a hous ing of the transcutaneous sensor to a skin site of a user or a patient. Further, the devices and the method according to the present invention may allow adherence of a medication device such as an insulin pump to the skin site of the user or the patient. Other applications are generally feasible.

Background art

Delivering medicine to a user, specifically insulin delivery, plays an important role in the prevention and treatment of diseases, in particular in the treatment of diabetes mellitus. Be sides using injection pens or syringes, insulin delivery may specifically be performed by using insulin pumps. In particular, a user is generally required to wear the insulin pump on his or her body at all times. Common pumps for delivering medicine, such as for example insulin, comprise one or more medicine reservoirs. As an example, fluid delivery devices are disclosed in WO2011/046950 Al.

Further, in the field of medical technology and diagnostics, a large number of devices and methods for determining a presence and/or a concentration of one or more analytes in sam ples, specifically fluid samples, such as body fluids, and/or for determining at least one pa rameter of a sample are known. For performing fast and simple measurements, several types of test elements are known, which mainly are based on the use of one or more test chemicals, i.e. on the use of one or more chemical substances, one or more chemical compounds or one or more chemical mixtures, adapted for performing a detection reaction for detecting the analyte or determining the parameter. The test chemical often is also referred to as a test substance, a test reagent, a test chemistry or as a detector substance. In addition to so-called spot measurements, in which a sample of a body fluid is taken from a user in a targeted fashion and examined with respect to the analyte concentration, continuous measurements are increasingly becoming established. Thus, in the recent past, continuous measuring of glucose in the interstitial tissue (also referred to as continuous monitoring, CM) for example has been established as another important method for managing, monitoring and controlling a diabetes state. In the process, the active sensor region is applied directly to the measure ment site, which is generally arranged in the interstitial tissue, and, for example, converts glucose into electrical charge by using an enzyme (e.g. glucose oxidase, GOD), which charge is related to the glucose concentration and can be used as a measurement variable. Examples of such transcutaneous measurement systems are described in US 6,360,888 B1 or in US 2008/0242962 Al. Hence, current continuous monitoring systems typically are transcutane ous systems or subcutaneous systems, wherein both expressions, in the following, will be used equivalently. This means that the actual sensor or at least a measuring portion of the sensor is arranged under the skin of the user.

Commonly, medical pumps and devices configured for determining a presence and/or a con centration of one or more analytes in samples may be configured for attachment to a skin site of the user or the patient. For this purpose, generally, at least one surface of the medical pump and of the device configured for determining a presence and/or a concentration of one or more analytes in samples may comprise at least one adhesive material configured for attachment of the skin site of the user or the patient. Typically, the medical pump and the device configured for determining a presence and/or a concentration of one or more analytes in samples respectively typically stay on the skin site for several days such as for a time period of two to five days or even one or two weeks. As manufacturing costs of the device configured for determining a presence and/or a concentration of one or more analytes in samples are commonly high, such devices are commonly intended to be in use as long as possible, specifically as health care systems commonly only refund equivalent values of a few test strips per day. Commonly, an attractivity of such devices increases with the capa bility of such devices to replace as much test strips as possible.

In US 2011/319733 Al devices, systems, methods and kits for releasably mounting a medi cal device on the body or skin of a user are described. Specifically, a structure adapted for mounting a medical device on the body of a host is described. The structure comprises a first portion and a second portion moveable relative to the first portion. The movement of the second portion relative to the first portion causes a release of at least a portion of a medical device from the first and second portions when operatively mounted thereon. In US 2018/0348048 systems and methods for mounting optical sensors in physiological monitoring devices worn by a user to sense, measure, and/or display physiological infor mation are described. Optical sensors may be mounted in the rear face of the device, emit light proximate a targeted area of a user's body, and detect light reflected from the targeted area. The optical sensor may be mounted in a housing or caseback such that at least a portion of the optical sensor protrudes a distance from at least a portion of the housing. The protru sion distance may be adjustable such that a user may achieve a customized fit of the wearable device. Adjustment of the protrusion distance may also result in a customized level of contact and/or pressure between the optical sensor and the targeted area which may, in turn, result in more reliable and accurate sensing of physiological information.

Despite the advantages of state of the art devices, several technical challenges remain. Spe cifically, many users or patients are not able to take use of medical pumps and devices con figured for determining a presence and/or a concentration of one or more analytes in samples because of skin intolerance against the adhesive of a housing of the medical pump or of the device configured for determining a presence and/or a concentration of one or more analytes. Within just a few days or even hours after mounting the medical pump or the device config ured for determining a presence and/or a concentration of one or more analytes via the ad hesive material on the skin site, the skin site may be irritated. As a consequence, the user or the patient may remove the medical pump or the device configured for determining a pres ence and/or a concentration of one or more analytes from the skin site although the life time of the medical pump or the device configured for determining a presence and/or a concen tration of one or more analytes has not yet expired.

Problem to be solved

It is therefore an objective of the present invention to provide a holder for a medical device, a kit and a method for mounting a medical device on a skin site of an extremity of a user which at least partially avoid the shortcomings of known devices and methods of this kind and which at least partially address the above-mentioned challenges. Specifically, devices and methods shall be disclosed which allow for an adherence of a medical device, specifi cally of a housing of the medical device, to a skin site of a patient or a user and, at the same time a risk of a skin intolerance of the patient or the user against an adhesive of the housing of the medical device shall be avoided.

Thus, the detection may be or may comprise a qualitative detection, simply determining the presence of the at least one analyte or the absence of the at least one analyte, and/or may be or may comprise a quantitative detection, which determines the quantity and/or the concentration of the at least one analyte. As a result of the detection, at least one signal may be produced which characterizes an outcome of the detection, such as at least one measurement signal.

Specifically, the medical device may have a transcutaneous insertable portion. As used herein, the term “transcutaneous insertable portion” refers to a component, e.g. to a part of an arbitrary device, which is adapted to be fully or at least partly arranged within a body tissue of the patient or the user. For this purpose, the transcutaneous insertable portion gen erally may be dimensioned such that a transcutaneous insertion is feasible, such as by provid ing a width in a direction perpendicular to an insertion direction of no more than 5 mm, preferably of no more than 2 mm, more preferably of no more than 1.5 mm. The transcuta neous insertable portion may have a length of less than 50 mm, such as a length of 30 mm or less, e.g. a length of 5 mm to 30 mm. It shall be noted, however, that other dimensions are feasible. The transcutaneous insertable portion may fully or partially provide a biocom patible surface, i.e. a surface which, at least during durations of use, do not have any detri mental effects on the user, the patient or the body tissue.

The term “insertable portion” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an arbitrary portion of an element which may be configured to be at least partially insertable into another object such that the insertable portion may be at least partially located under the object or surrounded by an interior of the object. Specifically, the insertable portion may be configured to be at least partially inserted into the body tissue, specifically under the skin of the patient. Therefore, the insertable portion may specifically have an elongate shape with a small cross-section. Exemplarily, the transcutaneously insertable portion may be selected from the group con sisting of: a sensor, preferably an analyte sensor for detecting at least one analyte in a body fluid, preferably a glucose sensor; an infusion cannula, preferably an insulin infusion can nula.

Thus, the housing may comprise at least one attachment component which is capable of forming a connection to the skin site, such as at least one adhesive surface and/or at least one adhesive strip or plaster.

The term “holder” as used herein is a broad term and is to be given its ordinary and custom ary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to an element that holds another object in a desired position. Specifically, the holder may be configured to fix, specifically to mount the object to a further object. Thus, as a consequence, the object may be mounted on, specifically attached to, the further object via the holder. While the object is held by the holder, a movement or shifting of the object relative to the holder may be pre vented at least to a large extent. Thus, by rotating, shifting or conducting other movements of the holder, the object may stay on the holder. The holder may generally be configured to establish an adhesive bond to the object. Thus, the holder may also be referred to as a mount, a mounting support or a support.

The holder may be configured for being wrapped around an extremity, specifically around an arm. As outlined above, the extremity may specifically be the upper arm. The extremity may correspond to a body portion where the medical device shall be placed. The holder may provide a surface formed and dimensioned for receiving the medical device.

Further, the straps of the holder may comprise a width of 10 mm to 300 mm, preferably of 15 mm to 60 mm, more preferably of 20 mm to 40 mm. Other dimensions may be feasible.

The holder may specifically be embodied as an elongate object which may be configured as a surrounding or enclosing structure, surrounding or enclosing the extremity, specifically the upper arm. The holder may specifically be a three-dimensional structure being configured for encompassing the extremity at least partially. A distance between a surface of the ex tremity, specifically the skin site of the user or the patient, and a surface of the holder may have a constant value. Specifically, the surface of the holder may be configured to be in direct contact with the surface of the extremity. As used herein, the term “at least partially encompass” may generally refer to a situation in which one object A encloses a circumfer ence of another object B at at least one position or section of the object B.

The holder may specifically be a flexible holder. The term “flexible holder” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifi cally may refer, without limitation, to an arbitrary holder having portions which may be bendable or deformable by forces which usually occur during holding the portions of the holder with both hands and moving the hands relative to each other, such as forces of 10 N or less. Specifically, the flexible holder may be made of or may contain at least one deform able material, such as at least one plastic or malleable material and/or at least one elastic material. The flexible holder may specifically deform reversibly and may return at least par tially to its original shape when an applied stress is removed. The holder may specifically be partially flexible. Thus, the holder may have portions with stiff or rigid properties. Specifi cally, the straps may be at least partially flexible and the mounting device may be embodied as a stiff component which will further be described below in more detail. However, also other embodiments may be feasible.

As outlined above, the holder comprises the mounting device. The term “mounting device” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a device which is configured to mount, specifically to fix or to attach, an arbitrary object to another element, specifically in a desired position. Thus, as a consequence, the object may be mounted on, specifically fixed or at tached to, the other element via the mounting device. While the object is held by the mount ing device, a movement or shifting of the object may be prevented at least to a large extent. Thus, by rotating, shifting or conducting other movements of the other element, the object may stay on the mounting device. Specifically, the object may refer to the housing of the medical device as described above or as will further be described below in more detail. Fur ther, the other element may refer to the extremity of the user or the patient. Thus, the mount ing device may generally be configured to establish an adhesive bond to the housing of the medical device. Further, the mounting device may generally be configured to establish at least one of a form-fit, a force-fit connection or an adhesive bond to the extremity of the user or the patient. Thus, the mounting device may be configured as a connecting element or binding element between the housing of the medical device and the extremity of the user or the patient. Specifically, in a mounted state of the housing of the medical device to the ex tremity the mounting device may maintain the form-fit, and/or force-fit connection and/or the adhesive bond to the housing and the extremity, respectively. Thus, in the mounted state, the mounting device itself may be fixedly attached to at least one of the housing, the extrem ity. Also other embodiments may be feasible. The mounting device may be embodied as a component of the holder. Thus, the mounting device may also be referred to as a mounting portion.

As outlined above, the mounting device comprises the first side and the opposing second side. The term “side” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to different sur faces forming an outside of an arbitrary object. The terms “first side” and “second side” may be considered as nomenclature only, without numbering or ranking the named elements, without specifying an order and without excluding a possibility that several kinds of first sides and second sides may be present. Further, additional sides such as one or more third sides may be present.

The first side and the second side may specifically respectively refer to longitudinal sides of the holder. Thus, shorter sides of the holder may respectively extend transverse, specifically perpendicular, to the first side and the second side. The second side may specifically refer to a rear side of the holder and the first side may specifically refer to a front side of the holder. In a mounted state of the holder wherein the holder is fixedly connected to an extremity of the user or the patient, the second side may face a skin site of the user or the patient and the first side may face an outer environment of the user of the patient.

Further, the medical device may be attachable to the holder on the first side. The first side of the mounting device may specifically comprise at least one flat surface configured for attachment of the medical device. In turn, the medical device, specifically the housing of the medical device may have at least one flat medical device surface. The flat surface of the first side of the mounting device and the flat medical device surface of the medical device may be configured to be laid up on top of each other. The flat design respectively of the flat surface of the first side of the mounting device and the flat medical device surface of the medical device may specifically lead to a large contact area between the medical device and the holder, specifically between the mounting device of the holder and the housing of the medical device and lead to a stable connection between the medical device and the holder.

Specifically, the flat surface may be a rough surface, specifically a slightly rough surface. This may lead to an improved adherence of the medical device to the holder, specifically of the housing of the medical device to the mounting device of the holder. Specifically, the rough surface may have a roughness of 0.2 pm to 100 pm, preferably of 0.4 pm to 50 pm, more preferably of 1 pm to 10 pm. Alternatively, the flat surface may be a smooth surface and may specifically be manufactured as a single piece. The flat surface may be made of at least one material selected from the group consisting of: polyurethane, neoprene. Also other materials may be feasible. Specifically, the flat surface may be made of at least one material having a Shore hardness A of 60 to 100, preferably of 70 to 90.

As outlined above, the second side of the mounting device may be configured for facing the skin site of the user or the patient.

The mounting device may have a thickness of 0.1 mm to 2 mm, preferably of 0.3 mm to 1 mm, preferably of 0.4 mm to 0.7 mm, most preferably of 0.5 mm. The term “thickness” may generally refer to a lateral extension of an arbitrary device in one direction. Specifically, the term “thickness” may refer to a lateral extension of the mounting device transverse, specifi cally perpendicular, to a direction of extension of the mounting device. The thin design of the mounting device may specifically be advantageous as, typically, the medical device is configured for direct attachment of the skin site of the patient or the user via an adhesive material. The thickness may relate to the lateral extension of the mounting device without taking into account the collar which is in one embodiment comprised in the holder.

Further, the mounting device may be at least partially made of a rigid material. The term “rigid material” generally describes a property of an arbitrary solid material of being unable to bend out of shape. Thus, the rigid material may be resistant against deformation inde pendently from an amount of stress which is applied on the rigid material. Thus, a strain may be zero or at least close to zero and a Young’s modulus may be > 1000 MPa. Thus, a high stability for the medical device may be provided. The mounting device may be made of a thermoplastic and/or duroplastic material, specifically of a material selected from the group consisting of: polycarbonate (PC), polyurethane (PU), polycarbonate- acrylonitrile-butadi- ene-styrene blends (PC-ABS blends). Also other materials may be feasible. Further, a hard rubber material having a Shore hardness A of at least 90 may be applicable.

As outlined above, the mounting device comprises at least one hole reaching from the first side to the second side. The term “hole” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limita tion, to an opening, a cavity or a hollow space within an arbitrary object. The hole may specifically have a round ground shape. However, other shapes may be feasible. Specifically, the hole may be a through hole. The term “through hole” may generally refer to a hole of an arbitrary object which fully penetrates the object. The object may have at least two opposing sides and the through hole may extend from one of the two sides to the other one of the two sides thereby penetrating each of the two sides. Thus, the through hole may form a connec tion between the two sides. The hole may specifically be located in a center of the mounting device. Exemplarily, the mounting device may have a circular shape and a position of the hole may correspond to a center of a circle. However, other positions of the hole may also be feasible.

A distance between a surface of the object and a surface of the strap may have a constant value. Specifically, the surface of the strap may be in direct contact with the surface of the object.

As outlined above, the straps are respectively attached to the mounting device. The term “being attached to“ as used herein is a broad term and is to be given its ordinary and cus tomary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a state of at least one object and at least one other object wherein the object and the other object are in contact with each other in such a way that the object does not come off the other object or vice versa without exerting additional forces to the object or the other object in order to remove these objects from each other. Specifically, the straps may respectively be firmly attached to the mounting device. Thus, the straps and the mounting device may respectively be made of different materials. However, other embodiments may be feasible.

At least one of the two straps may be an elastic strap. Thus, exemplarily, at least one of the two straps may be made of at least one elastic material. The term “elastic” may generally refer to a property of an arbitrary object being made of a material of being deformable by up to at least 10%, at least 25%, at least 50% or at least 75%, at least 100%, or at least 150% of a dimension, such as a length of at least one section of the object when stretched parallel to a surface with a force of up to 100 Newton, up to 50 Newton or up to 10 Newton, preferably between 10 to 50 Newton. Thereby, the object may return to an original size and shape when the force is removed. The elastic material may be selected from the group consisting of: a silicone polymer; a silicone copolymer; an elastomer comprising at least one silicone copol ymer; a rubber material, specifically neoprene; polyurethane. However, other materials may be feasible. Specfically, the elastic properties of the straps may be achievable by a stretchable material or by a combination of limited resilience of the material and a shape that supports a prolongation of the straps in one direction under load, e.g. via a sinuous cross section. Further, specifically, at least one of the two straps may be made of at least one foamed ma terial. The term “foamed material” may generally refer to an arbitrary material which is formed by trapping pocket of gas in the material, which may specifically be a solid material. The foamed material may have closed cells and/or open cells. The closed cells may form discrete pockets, each completely surrounded by the solid material. The open cells may be connected to each other. Thus, liquid may flow through a structure formed by the open cells. Preferably, the foamed material may have open cells. The open cells may have an average size of 0.01 mm to 1 mm, preferably of 0.1 mm to 0.5 mm. However, also other dimensions may be feasible. Thus, sweat of the user or the patient or other fluids such as water may be absorbed and an effect on a slip resistance of the straps may be avoided.

The foamed material may comprise at least one material selected from the group consisting of: a silicone polymer; neoprene; polyurethane. However, other materials may be feasible. Also woven or unwoven fibers can serve as bendable nonetheless load carrying material.

As outlined above, the two straps are fixedly connectable to each other. The term “connect able” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifically may refer, without limitation, to a property of an object to be placeable into and fixable in close physical proximity to another object. In particular, the object that is connectable to another object may be in direct or indirect physical contact with the other object when it is connected to it. The term “fixedly connectable” as used herein is a broad term and is to be given its ordinary and customary meaning to a person of ordinary skill in the art and is not to be limited to a special or customized meaning. The term specifi cally may refer, without limitation, to a state of at least one object and at least one other object wherein the object and the other object are in contact with each other in such a way that the object does not come off the other object or vice versa without exerting additional forces to the object or the other object in order to remove these objects from each other.

Further, the two straps may be releasably connectable to each other. As further used herein, the term “releasable”, in the context of a mechanical connection, refers to the fact that the mechanical connection may be brought from a disconnected state, also referred to as a non- mated state, into a connected state, also referred to as a mated state, and back into the dis connected state at least once, preferably several times. Thus, the mechanical connection may be closed and released at will. Specifically, the mechanical connection may be releasable without using any tools, simply by manual action. As an example, for opening a connection between the two straps forces of no more than 50 N, such as of no more than 20 N, such as of no more than 10 N, may be required. The force may be applied by one hand or even the fingers or fingertips of the user or the patient.

The at least two straps may specifically be fixedly connectable to each other by at least one of a button, a snap, a hook-and-eye-closure, a magnetic locking, a side release buckle, a zipper. However, other closing mechanism may be feasible. Further, a length of at least one of the two straps may be adjustable. Thus, the holder may be adaptable to a circumference of the extremity of the user or the patient.

In a further aspect of the present invention, a kit is disclosed. The kit comprises the holder as described above or as will further be described below in more detail. The kit further com prises the medical device having at least one transcutaneously insertable portion.

The term “inserter unit” may gener ally refer to an arbitrary obj ect which is configured for inserting an element into a body tissue of a user or a patient. After the process of insertion, the inserter unit, or at least one compo nent of the inserter unit, may stay within the body tissue of the user or the patient or may be removed from the skin site. Specifically, the inserter unit may have an insertion cannula. The term “insertion cannula” may generally refer to an arbitrary element which may be insertable into the body tissue of the user, particularly in order to deliver or to transfer a further element. The further element may specifically be the transcutaneously insertable portion. Therefore, the insertion cannula may specifically be or may comprise a hollow tube or a hollow needle. Further, the insertion cannula may be one of a slotted cannula, a punched cannula, a cannula having a curved shape. Also other embodiments may be feasible. The insertion cannula may be configured to be inserted vertically or at an angle of 90° to 30° to the body tissue of the user or the patient, wherein an angular point of the angle corresponds to a puncture site of the insertion cannula on the body tissue . However, also other embodiments may be feasible. Specifically, the medical device may be received in the inserter unit. More specifically, the medical device may be enclosed by the inserter unit at least partially. However, also other embodiments may be feasible.

The collar as described above may have a shape which corresponds to a shape of the inserter unit. Specifically, the collar and the inserter unit, specifically a bottom part of the inserter unit, may have a complementary geometric shape which fit into one another. The mounting device, specifically the first side of the mounting device surrounded by the collar, may have a shape which corresponds to a shape of the inserter unit, specifically to a shape of the bottom part of the inserter unit. Exemplarily, the collar may enclose a circular shape and the the inserter unit, may have a circular shape as well. However, other shapes may be feasible. However, an average diameter of an area enclosed by the collar may be larger than the at tachment surface of the medical device such that the medical device may fit into the mount ing device. The collar may be dimensioned such that the inserter unit may only have little play within the holder, specifically within the collar. Thus, the collar may be configured for centering the transcutaneously insertable portion of the medical device. The collar may be configured to facilitate a centric alignment of the inserter unit. Thus, an undesired puncturing though the mounting device may be avoided. In a further aspect of the present invention, a method for mounting a medical device com prising at least one transcutaneously insertable portion on a skin site of an extremity of a user is disclosed.

The method comprises the method steps as given in the independent claims and as listed as follows. The method steps may be performed in the given order.

Further, one or more of the method steps may be performed repeatedly. Further, additional method steps may be present which are not listed.

The method comprises the following steps: a) mounting the holder as described above or as will further be described below in more detail on the skin site of the extremity of the user by fixedly connect ing the two straps with each other; b) placing an inserter unit comprising the medical device on the first side of the mounting device such that an end of the transcutaneously insertable portion and the hole are congruent with each other; and c) inserting the transcutaneously insertable portion into the skin site through the hole of the mounting device.

For further details on the medical device, the transcutaneouly insertable portion and the in serter unit, reference is made to the description above.

The medical device may be placed on the first side of the mounting device of the holder such that the adhesive surface of the medical device faces the first side of the mounting device of the holder. Specifically, in step b) the medical device may be placed on the mounting device such that the medical device touches the first side of the mounting device. Alternatively, in step b), the medical device may be arranged in a distance to the mounting device. The med ical device and the inserter unit may be placed on the mounting device separately. Exempla- rily, the medical device may be placed on the mounting device before the inserter unit is placed on the mounting device. However, alternatively, the medical device and the inserter unit may be commonly placed on the mounting device.

In step b), the inserter unit may be placed on the mounting device such that the inserter unit is enclosed by the collar. During step c), an insertion mechanism of the inserter unit may be conducted. In case the medical device may be arranged in a distance to the mounting device the mounting device may be moved towards the first side. Further, the inserter unit may be removed from the mounting device after insertion of the transcutaneously insertable portion into the skin site.

The housing may comprise the at least one opening, specifically at least one exit spot, for the transcutaneously insertable portion. The medical device may be placed on the first side of the mounting device such that the exit spot lies in the center of the hole.

The proposed holder for a medical device, the proposed kit and the proposed method for mounting a medical device on a skin site of an extremity of a user provide many advantages over known devices and methods. Thus, specifically, the devices and method according to the present invention allow for an adherence of a medical device, specifically of a housing of the medical device, to a skin site of a patient or a user while, at the same time, a risk of a skin intolerance of the patient or the user against an adhesive of the housing of the medical device is avoided.

Specifically, the straps may be made of a slip-resistant material. Further, the straps may be made of a material having a good inherent elasticity. Further, a length of the straps may be adjustable. The holder may be mounted on the extremity such that a shifting of the holder may be avoided.

The medical device may comprise the at least one exit spot for the transcutaneously inserta ble portion and the medical device may be placed on the first side of the mounting device such that the exit spot lies in the center of the hole. For this purpose, the mounting device may comprise the collar. The inserter unit may fit into the collar only with very little play. After the inserter unit has been triggered and the transcutaneously insertable portion has been placed into the skin site of the user or the patient, the inserter unit may be removed. The housing may remain on the mounting device of the holder, but not directly on the skin site of the user or the patient.

The straps may be made of the foamed material such as made from a silicone polymer, neo prene, poly urethane. Thus, sweat of the user or the patient may be absorbed and an effect on a slip resistance of the straps may be avoided.

The mounting device may be embodied very thin. Specifically, the mounting device may have a thickness of 0.5 mm as the medical devices are configured for direct attachment of the skin site of the patient or the user. In order to provide a sufficient stability, the mounting device may be made of a rigid material such as of a hart plastic material.

Further, the collar may be dimensioned such that a stability of the medical device may be provided. The straps may be tensioned on the extremity in a soft manner. Thus, the skin may intend to bulge outwardly. However, this may be prevented or at least diminished by the stiff housing of the medical device. As a consequence, the skin may be pressed against the soft straps and a safe fit of the sensor may be enabled.

The first strap 118 and the second strap 120 may be fixedly connectable to each other. Exemplarily, as illustrated in Figure 1 A, the first strap 118 may have at least one hole 156, specifically at least one through hole 158. The second strap 120, in turn, may comprise a protrusion such as a hook (not shown). The protrusion may be configured to be hooked into the hole 156 thereby forming a connection between the first strap 118 and the second strap 120. Specifically, the first strap 118 may comprise a plurality of the holes 156 arranged in one row. Thus, the holder 110 may be adaptable to a circumference of the extremity of the user or the patient.

Figure IB shows the holder 110. With regard to details on the holder 110 reference can be made to the description of Figure 1A above. Further, in Figure IB, the medical device 112 is depicted. Specifically, a kit 160 is shown. The kit 160 comprises the holder 110 and the medical device 112. Further, the kit 160 may comprise at least one inserter unit 164. The inserter unit 164 may be configured for inserting the transcutaneously insertable portion into the body tissue of the user or the patient. After the process of insertion, the inserter unit 164 may be removed from the mounting device 114. This state is shown in Figure 1C which will further be described below in more detail.

The medical device 112 comprises the at least one transcutaneously insertable portion (not shown) and at least one housing 162 which is shown in Figure 1C.

The inserter unit 164 may have an inserter unit housing 166. The inserter unit housing 166 may be configured to attach to the first side 122 of the mounting device 114. Specifically, the inserter unit housing 166 may be configured to fit into the collar 144 only with very little play. The inserter unit 164 may comprise at least one button 168. By pressing the button 168 towards the mounting device 114 such as illustrated with arrow 170 an insertion mechanism may be triggered. Thus, the transcutaneously insertable portion may be placed at least par tially within the skin site of the user or the patient.

Figure 1C shows the holder 110. With regard to details on the holder 110 reference can be made to the description of Figure 1A above. Further, in Figure 1C, the medical device 112 is depicted. Specifically, the kit 160 is shown.

In Figure 1C, the housing 162 of the medical device 112 is shown. The housing 162 may be attachable to the first side 126 of the mounting device 114, specifically to the surface 130. When triggering the insertion mechanism by pressing the button 169 of the inserter unit 164 such as illustrated in Figure IB, the housing 162 may be moved from an interior of the in serter unit 164 to the surface 130 of the mounting device. After removing the inserter unit 164 from the mounting device 114 the medical device 112 may stay on the mounting device 114. For this purpose, the medical device 112 may have at least one attachment component (not shown) which is capable of connecting the medical device 112 to the first side 122 of the mounting device 114, such as at least one adhesive surface.

The housing 162 may specifically be an electronics unit 174 having at least one component for one or more of performing a measurement with the sensor, performing a voltage meas urement, performing a current measurement, recording sensor signals, storing measurement signals or measurement data, transmitting signals or measurement data to another device. The electronics unit 174 may specifically be embodied as a transmitter or may comprise a transmitter, for transmitting data.

The housing 162 may have an opening 176, specifically a through opening 178. The housing 162 may be placed on the first side 122 such that the opening 176 lies in the center of the hole 138 of the mounting device 114 such as illustrated in Figure 1 A. Thus, an insertion aid of the inserter unit 164 such as an insertion cannula (not shown) may be removed from the body tissue after insertion via the opening 176.
