Fabric covered polymeric prosthetic liner

摘要

A prosthetic cushion liner and cushion locking liner for use as a standalone interface between an amputee's residual limb and the interior of a prosthetic socket. The liners include a fabric covering having an open end for introduction of a residual limb and a closed end opposite said open end, and a cushioning block copolymer and plasticizing oil gel composition residing on only an interior surface of the fabric covering. The gel composition includes some amount of a Septon J-Series thermoplastic elastomer material, and/or some amount of a Septon V-Series thermoplastic elastomer material, and/or some amount of a Septon Q-Series thermoplastic elastomer material. The cushion locking liner further includes a distally-located connecting element for coupling the liner to the socket of a prosthesis.

1. A prosthetic cushion liner, comprising:
a fabric covering having an open end for introduction of a residual limb and a closed end opposite the open end; and a continuous layer of a gel composition residing on an interior surface of the fabric covering, the gel composition comprising:
(1) a plasticizing oil;(2) a first thermoplastic elastomer, the first thermoplastic elastomer comprising a hydrogenated styrenic thermoplastic elastomer; and(3) polyethylene, in an amount of between about 0.1 weight percent and about 0.5 weight percent, wherein the gel composition has a Shore 00 hardness of between about 15 and about 35.
