ABSTRACT:
A hypobarically-controlled artificial limb for amputees includes an outer socket, a flexible, compressible inner socket within the outer socket with a cavity for receiving the residual limb, a space between the inner socket and the outer socket, a vacuum source connected to the cavity, a positive pressure source connected to the space, a regulator for controlling the vacuum source and positive pressure source, and a seal for making an airtight seal between the residual limb and the socket. Another embodiment includes a semi-compressible molding material in the space to mold to the contours of the residual limb under the influence of vacuum and/or positive pressure. Another embodiment includes a positive mechanical interlock between the inner socket and the outer socket.
