Description

[0039] Examples of embodiments of the invention are explained in more detail below with reference to the figures. They show:

[0040] FIG. 1—a schematic representation of a prosthetic cosmetic cover with a multi-part base body;

[0041] FIG. 2—a sectional view through a prosthetic cosmetic cover with schematically shown prosthesis;

[0042] FIG. 3—schematic representations of a connection part with two variants of conductor routing; and

[0043] FIG. 4—a variant with a partially embedded connection part.

[0044] FIG. 1 shows a schematic representation of a prosthetic cosmetic cover 1 with ax{circumflex over ( )}{circumflex over ( )} base body 11, which has a cavity 12 for at least partially accommodating a prosthetic component 3 shown in FIG. 2. An inner side 13 of the base body 11 faces the prosthetic component 3, and an outer side 14 faces away from the prosthetic component 3. All the sides that point away from the prosthetic component 3 or point past the prosthetic component are to be understood as facing away from the prosthetic component 3, in particular also upper sides of end edges of the base body 11.

[0045] In the embodiment according to FIG. 1, a lower leg prosthetic cosmetic cover is shown. A lower leg prosthesis, at the proximal end of which a prosthetic knee joint is connected, can be at least partially accommodated in the cavity 12. At a proximal end, the base body 11 is provided with a connection part 4, which forms the termination of the proximal end of the base body 11 in the form of a closed contour.

[0046] As a component of the base body 11, the connection part 4 has an inner side 41 facing the prosthetic component 3 and an outer side 42 facing away from the prosthetic component. The upper edge of the connection part 4 forms an outer side 42.

[0047] The connection part 4 may be formed of a more rigid material than the material of the rest of the base body 11. For the distal portion of the base body 11, which in the exemplary embodiment covers the prosthetic component 3 and has the shape of a lower leg, foams have proven useful, for example. Foams have a low density, so that a design of components of the base body 11 made of a foam ensures the provision of a light prosthetic cosmetic cover. The connection part 4 can be made of a plastic which has a higher rigidity than the foam of the distal part of the base body 11. The connection part 4 may be attached to the proximal end of the base body 11 in a form-fitting and/or material-bonded manner. For example, the connection part 4 can be foamed in during production of the remaining base body 11 from a foam material. It is also conceivable to glue the connection part 4 to the proximal end of the base body or to connect it in another suitable manner by way of material bonding. Alternatively, the connection part 4 is placed or plugged onto the rest of the base body 11 and clamped in place or fixed by form-fit elements.

[0048] The connection part 4 can be brought into form-fitting engagement with a section of a prosthetic component 3. Projections or recesses on the inner side 41 of the connection part 4 can engage with corresponding recesses or projections on the prosthetic component 3.

[0049] In the illustrated embodiment example, electrical connection elements 21, 22 are arranged in the connection part 4. Here, a first connection element 21 is arranged on an inner side 41 of the connection part 4 facing the prosthetic component 3 or the cavity 12. The second connection element 22 is arranged on an outer side 42 facing away from the prosthetic component 3 or the cavity 12. There is an electrical connection between the two connection elements 21, 22, exemplarily shown as an electrical conductor 23.

[0050] The first connection element 21 can be fixed in the connection part 4 in a form-fitting manner. This can be done by incorporating the connection element 21 during production of the connection part 4, so that it is cast in, for example. However, it is also conceivable that a suitable recess is drilled, milled or otherwise made in the connection part 4, with which the connection element 21 can be engaged in a form-fitting manner.

[0051] The electrical connection elements 21, 22 can be in the form of a plug, socket and/or electrical contact field. The electrical connection between the connection elements 21, 22 can be designed as an electrical conductor 23.

[0052] Insofar as the respective connection element 21, 22 is designed as an electrical contact field, it can have a magnetic securing. By means of a magnetic securing, a force-fit component acts on the contacting to ensure the hold.

[0053] In the embodiment shown, the electrical conductor 23 is arranged in the connection part 4 and is formed as an insulated cable; other embodiments are possible, for example printed conductor tracks, electrically conductive plastics or textiles or other signal and current conducting materials and components.

[0054] FIG. 2 shows a sectional view through a prosthetic cosmetic cover 1 with schematically shown prosthetic component 3. A data processing system 31 and/or a power supply system 32 is arranged inside the prosthetic component 3 that has an interface 33 for connection to an external source not shown.

[0055] In the illustrated embodiment, the first connection element 21 is arranged on the inner side 41 of the connection part 4. The form-fitting fixture of the connection element 21 in the connection part 4 ensures the secure hold of the connection element 21. The connection element 21 and the interface 33 are arranged in a corresponding manner, so that when the prosthetic cosmetic cover 1 is applied, the connection element 21 and the interface 33 can be directly electrically connected.

[0056] The connection elements 21, 22 are electrically connected to each other via the electrical conductor 23. When an external source is connected to the second connection element 22, the data processing system 31 and/or the power supply system 32 is supplied by the external source via the contacting of the first connection element 21 with the interface 33. Connecting an external source enables the feeding and reading of data sets such as control parameters and/or the charging of an integrated energy storage device to provide the necessary electrical energy.

[0057] FIG. 3 shows possible configurations of a connection part 4 according to the invention with an inner side 41 facing the prosthetic component 3 and an outer side 42 facing away from the prosthetic component. A first electrical connection element 21 is arranged on the inner side 41, and a second electrical connection element 22 is arranged on the outer side 42. The connection elements 21, 22 are electrically connected to each other.

[0058] A duct 43 is introduced into the connection part 4, for example by milling, drilling, casting, screwing on, gluing on or by other suitable means. The electrical conductor 23 is placed and secured in the duct 43 after production of the connection part 4, so that a prosthetic component 3 arranged in the cavity 12 of the base body 11 cannot become entangled in or chafe against the conductor 23.

[0059] In a further embodiment, the electrical conductor 23 is arranged in the connection part 4. Depending on the manufacturing method, this can be done during or after completion of the production of the connection part 4. The electrical conductor 23 may be molded or incorporated during an injection molding process or an additive manufacturing process.

[0060] In FIG. 4, a variant of the invention is shown which corresponds substantially to FIG. 1, but only the base body 11 is shown in a sectional view. In contrast to FIG. 1, in FIG. 4 the connection part 4 is arranged on the inner side of the base body 11. In the illustrated embodiment, the connection part 4 is attached to a proximal edge of the prosthetic component 3. The attachment may be detachable, for example by a clamp connection, by at least one fastening element, by Velcro fasteners, bolts, hooks, sliders or the like. The prosthetic cosmetic cover 1 is arranged around the prosthetic component 3 on the outer side, wherein the former can be fixed in various ways to the prosthetic component 3, which in the illustrated embodiment is formed as a part of a prosthetic knee joint. Here, too, the fastening is advantageously carried out such that it can be repeatedly detached, but a permanent fastening, for example by means of material bonding or permanent bonding, may also be provided. The cavity 12 within the prosthetic cosmetic cover 1 is almost completely filled by the prosthetic component 3, and a free space for inserting a lower leg tube can still be seen at the distal end. In this cavity 12, the inner side 13 can be seen, which faces the prosthetic component 3. The connection part 4 has its inner side facing the prosthetic component 3 and its outer side points away from the prosthetic component 3. The outer side is at least partially covered by the base body 11 of the prosthetic cosmetic cover 1, leaving the second electrical connection element 22 accessible from the outside. The connection part 4 is formed of multiple parts, and the multiple parts of the connection part 4 can be attached to one another, for example by means of a Velcro fastener or by means of form-fitting elements, such that they can be detached.
