Prosthetic System

摘要

A prosthetic device having a housing, an axle, at least three housing vanes, a flow medium and a valve. The axle is disposed within the housing and moveable independently of the housing. The axle has an axle reservoir and at least three axle vanes extending from the axle to contact the chamber wall. The three housing vanes extend from a chamber wall and contact the axle. A first opening and a second opening are formed in each axle vane. The flow medium is contained entirely within the chamber and the axle reservoir. The valve is disposed in the axle and operable in response to movement of the axle in a first direction relative to the housing to allow the flow medium to enter the axle reservoir from the chamber for storage under pressure.

1. An apparatus for controlling movement of a prosthetic device, the apparatus comprising:
a housing comprising a first chamber; a storage chamber; a first member connected to the housing; an axle moveable independently of the housing; wherein the housing and axle are moveable relative to each other between a first position and a second position by placing an external force on the first member; a flow medium disposed within the first chamber and movable from the first chamber to the storage chamber for storage under pressure in response to movement of the housing in a first direction to the second position and to control movement of the flow medium from the storage chamber to first chamber when the external force is altered.
