Problems solved by technology

These valves consist of moving parts, so are prone to dirt and failure, require frequent maintenance, are complex to produce, and are costly
In addition, for example, the user of the prosthesis can also allow air to enter the cavity between the liner and the prosthesis stem due to inadvertent or incorrect operation of the valve, in which case it is not possible to ensure a reliable positioning of the prosthesis on the amputation stump

Embodiment Construction

[0048] Attached figure 1 Shown is a peristaltic pump 1 with a housing 2 with a circumferential wall 4, a cover 6 and a bottom 8 not shown in the figure. Attached figure 1 The first hose end 10 shown in FIG. 2 enters the housing 2 through a first opening 12 in the circumferential wall 4 of the housing 2. The second hose end 14 is led out from the housing 2 through the second opening 16. The motor 38 is arranged on the bottom 8.

[0049] Attached figure 2 Shown as figure 1 The schematic top view of the peristaltic pump 1 in the opened, it can be seen the circumferential wall 4 and the first hose end 10 and the second hose end 14 passing through the circumferential wall 4 via the first opening 12 and the second opening 16. The hose 18 extends along the circumferential wall 4 in the housing 2 itself. Attached figure 2 In the illustrated embodiment, the peristaltic pump 1 has two pump elements 20, both of which are designed in the form of rollers, which can be rotatably supported ...

Abstract

The prosthesis has a prosthesis shaft, which has an inner surface and is formed at an amputation socket. The amputation socket is arranged, such that inner surface is opposite to amputation socket. A pump is a peristaltic pump. The peristaltic pump has a housing with a peripheral wall, a base and a cover. A pump element is arranged in the housing. A friction-reducing layer, particularly polytetrafluoroethylene-fiber film is arranged at inner side of the cover or the inner side of the base of the housing. A hose is made from silicone or a thermoplastic elastomer or polyurethane.

Description

Technical field [0001] The present invention relates to a prosthesis having a prosthetic stem. The prosthetic stem has an inner surface and can be placed on the amputation stump so that the inner surface faces the amputation stump, and includes a prosthesis between the inner surface and the amputation stump. The cavity, the prosthesis also has a pump, after the prosthetic stem is placed on the amputation stump, it can be used to generate negative pressure in the cavity. Background technique [0002] Such prostheses have long been widely known from the prior art. Generally, a liner is first put on the amputation stump, and the liner may be, for example, a silicone material or polyurethane material that matches the shape of the corresponding amputation stump. Then put the prosthesis stem on the liner so that the inner side of the prosthetic stem faces the liner and the amputation stump. If a separate pad is not used, the inside of the prosthetic stem is directly facing the amputa...
