VALVE FOR PROSTHETIC DEVICE

摘要

A valve (200) for use with a prosthetic socket (14) includes a body (202) defining a first opening (226), a second opening (228) adapted to be in fluid communication with the socket cavity (15), and a passageway (224) formed between the openings (226, 228). A membrane (206) is flexibly seated on the body (202) over the first opening (226). The membrane (206) is movable between a closed position which the first opening (226) is sealed and fluid communication between the first opening (226) such that the second opening (228) is inhibited, and an open position in which the first opening (226) is unsealed such that fluid can flow through the passageway (224). The membrane (206) includes a first part (234) connected to a release element (208) that is operable to move the membrane (206) between the open and closed positions and a free part (232) that is operable independent of the first part (234) to move the membrane (206) between the open and closed positions.
