Suspension liner with seal component

摘要

A suspension liner is provided for use as an interface between a residual limb and a prosthetic socket. The liner has an elongate, generally conical liner body formed from at least one material segment that is at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas, and a seal component connected to the liner body and having an exterior surface defining at least one exterior seal protruding from the exterior surface and extending radially outwardly from the seal component relative to a longitudinal axis of the liner body. The at least one interior seal is located along an interior surface of the seal component and defines at least one blade extending obliquely toward the liner body. A portion of the seal component carrying the interior seal extends freely and is movable relative to the liner body.

1. A liner for providing an interface between a residual limb and a prosthetic socket, comprising:
an elongate, generally conical liner body being radially elastically extensible and including proximal and distal end areas, the liner body having an exterior surface and defining a longitudinal axis defined between the proximal and distal end areas; and a seal component connected to the liner body and having an interior seal configuration arranged to protrude from an interior wall of the seal component and extend toward the exterior surface of the liner body, the interior seal configuration including at least one blade extending toward the exterior surface of the liner body; wherein the seal component defines a distal outwardly pitched portion and a proximal inwardly pitched portion located at the uppermost end of the seal component, the interior seal configuration defined as a segment of the seal component connecting and confined between the distal outwardly pitched portion and the proximal inwardly pitched portion.
