Abstract
The present invention relates to a supporting sleeve for a leg or arm stumps, namely a liner. The liner includes a sleeve made of an elastomeric and electrically insulating material that surrounds the stump starting from the distal end thereof. The sleeve has at least in part a surrounding layer made of a suitably conductive material.
Claims11
A supporting sleeve for a body stump, said supporting sleeve having at least a distal end and an open receiving end, namely a liner, comprising:
- a sleeve member having an inner surface defining a concave shape proximate said distal end for bounding at least a portion of said body stump during a use thereof;
- said sleeve member being at least partially an elastic and an electrically insulating material along said inner surface;
- said sleeve member further comprises a first portion electrically conductive layer proximate said distal end and a second portion electrically conductive layer being spaced from said inner surface by at least a portion of said elastic and electrically insulating material of said sleeve member along said open receiving end;
- and
- means for forming a electrically conductive region between said first and second portions of and said electrically conductive layer including a liner cup member at said distal end of said sleeve member.
2 more elements
A supportive member, configured to conform to an external stump comprising:
- a supportive concave sleeve having an inner surface defining a receiving concave shape having an inner distal end and an opposing outer open non-distal end;
- said supportive concave sleeve being an elastic electrically insulating material;
- a partially rigid liner member in said supportive concave sleeve having a first portion and a second portion;
- said first portion of said liner member being electrically conductive and being on said inner surface of said concave sleeve at said distal end thereof opposite said non-distal end;
- a second portion of said liner member haying a concave shape and being electrically conductive and extending away from said first portion within an inner portion of said supportive concave sleeve, whereby said second portion is electrically conductive with said first portion but is spaced from said inner surface of said elastic insulating material of said sleeve and electrically separated there from;
- said first portion and said second portion of said liner member being an electrically conductive layer;
- said electrically conductive layer constructed from at least one of an electrically conductive elastomeric material, an electrically conductive textile material, an electrically conductive fiber material, an electrically conductive metallic material, and an electrically conductive plastic material;
- and
- an electrically conductive cup member in said electrically conductive layer proximate said first portion thereof.
