Abstract
A prosthetic liner includes a flexible elongate, generally conical body portion formed from an elastomeric material. The body portion defines an inner surface, an outer surface forming a liner profile between a distal end and a proximal end, and an axis extending between the distal and proximal ends. At least one seal element extends circumferentially about the axis and protrudes radially outward a distance from the liner profile. The at least one seal element has a seal height defined between the liner profile and a radially outward end of the at least one seal element. The seal height varies circumferentially about the axis between a first seal height and a second seal height.
Claims20
A prosthetic liner adapted to provide an interface between a residual limb and a prosthetic socket, the prosthetic liner comprising:
- a body portion having an elongate and generally conical shape and formed from an elastomeric material, the body portion defining an inner surface, an outer surface forming a liner profile between a closed distal end and an open proximal end, and an axis extending between the distal end and the proximal end;
- wherein the body portion includes a seal element region having at least one seal element formed by the prosthetic liner and the elastomeric material of the body portion;
- wherein the at least one seal element defines a trapezoidal shape having first and second plane side areas protruding radially outward from the liner profile relative toward each other, and further forms a radially outward end.
A prosthesis system comprising:
- a prosthetic socket adapted to a shape of a residual limb;
- and
- a prosthetic liner adapted to provide an interface between the residual limb and the prosthetic socket, the liner including:
- a flexible elongate, generally conical body portion formed from an elastomeric material, the body portion defining an inner surface, an outer surface forming a liner profile between a distal end area and a proximal end area, and an axis extending between the distal end area and the proximal end area;
- and
- at least one seal element extending circumferentially about the axis and protruding radially outward from the liner profile, at least one seal element arranged to bridge a seal between the prosthetic socket and the body portion;
- wherein the at least one seal element defines a trapezoidal shape having first and second plane side areas protruding radially outward from the liner profile relative toward each other, and further forms a radially outward end.
