SUSPENSION LINER SYSTEM WITH SEAL

摘要

A suspension liner sleeve adapted to provide an interface between a residual limb and a prosthetic socket, and having outer and inner surfaces. The liner sleeve includes an elongate, generally conical body portion formed from at least one material segment defining the liner outer surface. The at least one material segment being at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas. The liner sleeve includes a layer of polymeric material disposed on the at least one material segment and defining the liner sleeve inner surface, and a plurality of resilient seal elements protruding radially from the liner sleeve outer surface. The plurality of seal elements extend around at least one peripheral portion of the liner body portion. A pair of opposed annular recesses may be adjacently located above and below each of the at least one seal element.

1. A suspension liner adapted to provide an interface between a residual limb and a prosthetic socket, the suspension liner defining an interior surface and an exterior surface forming a liner profile between a closed distal end and an open proximal end, the suspension liner comprising:
a flexible elongate, generally conical liner body portion formed from an elastomeric material; a reinforcement material embedded into a thickness of the elastomeric material of the liner body portion, the reinforcement material being generally axially stiff and radially compliant, the reinforcement material being different from the elastomeric material; at least one seal protruding circumferentially about and radially outwardly a distance from the liner profile defined at areas outside the at least one seal, the at least one seal formed in one piece with the elastomeric material of the liner body portion, the at least one seal having a lower portion inclined radially outwardly and upwardly in a direction from the distal end toward the proximal end.
