Abstract:
1. A suspension liner system adapted to provide an interface between a residual limb and a prosthetic socket, said suspension liner system comprising: an elongate generally conical liner sleeve formed of a material that is at least elastically extendible from a relaxed non-extended condition and including an open proximal end area and a closed distal end area, the liner having a longitudinal axis; and a sealing member separate from and slidably fitting over the closed distal end area of the liner sleeve in an air tight relationship, the sealing member having proximal and distal end areas, and defining a resilient seal element located at the proximal end area and a receiving portion formed from the distal end area, the seal element outwardly protruding radially relative to the receiving portion at the distal end area of the liner sleeve and relative to the liner sleeve axis, the seal element and arranged for deflection against the liner sleeve at the distal end area of the liner sleeve; wherein the seal element of the sealing member comprises outwardly and inwardly pitched members joining at an annular peak extending radially outwardly from the proximal end area of the sealing member and relative to liner sleeve axis.
