Abstract:
1. A socket assembly for connecting a residual limb to a prosthetic limb, comprising: an elongated upper circumferential section having an open upper end and a distal end; an intermediate section extending from the upper section and tapering inwardly to a lower rim region; and a distal section extending from the lower rim region to a base of the socket; a one-way valve in fluid communication with an interior of the socket assembly; and a flexible diaphragm engaging the lower rim region of the intermediate section forming a cavity in the distal section beneath the flexible diaphragm, wherein the diaphragm has a convex lower surface that maintains a convex shape without compression by a limb and is shaped to substantially conform to the inwardly tapering lower rim of the intermediate section, and wherein a portion of the convex surface is positioned over the distal section to allow deflection of a portion of the convex surface of the flexible diaphragm into and out of the cavity during routine movements.
