Abstract: The invention relates to a device for connecting a pump, having a through-hole (42) provided in a prosthesis shaft (36), wherein the device comprises at least one channel (6) having a first outlet (4) for connecting to the through-hole (42) in the prosthesis shaft (36) and a second outlet (14) which can be connected to the pump and at least one valve (24), characterized in that the valve (24) can be switched to a first mode and to a second mode, wherein the valve (24) is a one-way valve in the first mode and a two-way valve in the second mode.

Abstract: The invention relates to a pump comprising a wall, which forms an enclosed fluid volumetric space and which can be moved by a first force in a direction resulting in a decrease in volume and, after a preceding decrease in volumetric space, can be moved by a second force in a direction resulting in an increase in volume. The pump also comprises an inlet valve, which communicates with an inlet valve, and comprises an outlet valve in an outlet line of the fluid volumetric space. The inventive pump has a compact design due to the fact that it is provided in the form of a vacuum pump whose volumetric space can be decreased by the external first force acting against an elastically deformable material whose restoring force, after the external force ceases, generates the second force acting counter to the generated vacuum.
