Abstract
An adjustable seal system includes a suspension liner having a liner body and an outer surface. A plurality of seal bands are located along a height of the liner body. A seal component is arranged for removably securing to the liner body. The seal component includes open upper and lower ends defining an opening therethrough and an internal surface arranged to frictionally engage at least one of the seal bands and secure on the outer surface of the liner. The seal component also includes an upper portion descending to at least one seal, and a lower portion.
Claims9
An adjustable seal system comprising:
- a prosthetic socket having an interior wall;
- a suspension liner positionable in the prosthetic socket, the suspension liner having a liner body and an outer surface, the outer surface including a plurality of seal bands located along a height of the liner body;
- a seal component arranged for removably securing to the liner body, the seal component including:
- open upper and lower ends defining an opening therethrough and an internal surface arranged to frictionally engage a selectable one of the seal bands and secure on the outer surface of the liner;
- an upper portion descending from the upper end to a seal member;
- and
- a seal-assist system comprising a first magnetic part associated with the seal member and a second magnetic part associated with the prosthetic socket, the seal-assist system arranged to enhance a seal formed between the seal member and the interior wall of the prosthetic socket by forcing the seal member away from the upper portion and against the interior wall of the prosthetic socket when the seal component and the suspension liner are positioned in the prosthetic socket such that during connection of the seal member and the interior wall of the prosthetic socket a gap is formed between the seal member and the upper portion.

A prosthetic system comprising:
- a prosthetic socket having an interior wall;
- a suspension liner positionable in the prosthetic socket, the suspension liner having a liner body and an outer surface, the outer surface including a plurality of seal bands located along a height of the liner body;
- a seal component arranged for removably securing to the liner body, the seal component including:
- open upper and lower ends defining an opening therethrough and an internal surface arranged to frictionally engage a selectable one of the seal bands and secure on the outer surface of the liner;
- an upper portion descending from the upper end to a seal member;
- and
- a seal-assist system comprising one or more permanent magnetic materials associated with the seal member and a magnetic part associated with the prosthetic socket, the seal-assist system arranged to enhance a seal formed between the seal member and the interior wall of the prosthetic socket by forcing the seal member away from the upper portion and against the interior wall of the prosthetic socket when the seal component and the suspension liner are positioned in the prosthetic socket, wherein the one or more permanent magnetic materials extend within the seal member entirely around the seal component.
