    摘要： A weight-actuated vacuum pump for a hypobarically-controlled artificial limb having a socket with a cavity to receive a residual limb. A dual-action pump has a housing fixedly attached to the socket of the artificial limb, a cylinder reciprocating within the housing and attached to the pylon of the artificial limb, a first chamber within the cylinder, a piston reciprocating within the first chamber, a second chamber between the cylinder and the housing, and valves for connecting the first chamber and second chamber to the cavity and to atmosphere. A single-action pump has a housing fixedly attached to the pylon of the artificial limb with a first chamber therein, a piston reciprocating in the first chamber with a seal, forming a second chamber between the piston and the housing, an intake/exhaust port connected to the second chamber, and one-way valves connecting the second chamber to the cavity and to atmosphere. Ambulation causes the vacuum pump, under the influence of the wearer's body weight, to draw air out of the cavity, producing a vacuum within the cavity.

    摘要： A hypobarically-controlled artificial limb for amputees includes a single socket with a volume and shape to receive a substantial portion of the residual limb. A liner with a volume less than the residual limb is donned over the residual limb, with the liner tensioned into a total contact relationship with the residual limb. A sealed cavity is formed between the socket and the liner. A vacuum source is connected to the socket cavity thereby drawing the residual limb and liner into firm and total contact with the socket. To compensate for some air leakage past the seal, there is a mechanism to maintain the vacuum in the cavity. An osmotic membrane encases the residual limb and creates a space between the residual limb and the liner. The osmotic membrane allows passage of water only in one direction: from the residual limb toward the liner. Vacuum may be applied to the space between the osmotic membrane and the liner to assist in wicking perspiration away from the residual limb.
