Socket liner for artificial limb

Abstract

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 sealed cavity is formed between the socket and the residual limb. Optionally, the wearer may use a liner over the residual limb for comfort. A vacuum source is connected to a vacuum valve connected to the cavity to suspend the artificial limb from the residual limb and to control and minimize volumetric and fluid changes within the residual limb. A liner for a hypobarically-controlled socket for an artificial limb, with: a) an inner layer contacting the residual limb; b) an outer fabric layer engaging the inner layer; and c) an annual seal extending outwardly from the outer fabric layer and sealingly engaging the suspension sleeve, thereby making a seal between the residual limb and the socket to minimize air leakage into the cavity.
