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 (14). A liner (92) with a volume less than the residual limb (14) is donned over ,the residual limb, with the liner (92) tensioned into a total contact relationship with the residual limb (14). A sealed cavity is formed between the socket, (60) and the liner (92). A vacuum source (70) is connected to the socket cavity (62) thereby drawing the residual limb (14) and liner (92) into firm and total contact with the socket (60). To compensate for some air leakage past the, seal (140), there is a mechanism to maintain the vacuum in the cavity.

L'invention concerne un membre artificiel d'amputés à régulation hypobare, qui comprend une emboîture dont le volume et la forme permettent de recevoir une partie importante du moignon. Un revêtement dont le volume est inférieur à celui du moignon est ajusté sur celui-ci, tendu et en contact étroit avec le moignon. Une cavité étanche est formée entre l'emboîture et le revêtement. Une source de vide est reliée à la cavité d'emboîture, mettant ainsi fermement en contact avec l'emboîture le moignon et le revêtement. Un mécanisme permet de maintenir le vide dans la cavité de façon à compenser une éventuelle fuite d'air par le joint d'étanchéité.
