Abstract
Prosthetic socket sealing systems and methods of use. Embodiments of the present invention include various combinations of sealing elements that are associated with a rigid prosthetic socket and act to seal the socket interior against air intrusion or escape via the open proximal end thereof. The socket interior may thus be evacuated for purposes of vacuum suspension or otherwise.
Claims24
An apparatus comprising:
- a prosthetic socket having an open proximal end configured for insertion of a residual limb, a distal end configured to reach across a distal end of the residual limb, a peripheral shoulder within the socket, an interior periphery reaching from the shoulder to the distal end, and an enlarged interior periphery reaching from the shoulder to the open proximal end;
- and
- a ring-shaped inner brim received within the enlarged interior periphery of the socket between the shoulder and the open proximal end of the socket.
An apparatus comprising:
- a prosthetic socket having an open proximal end configured for insertion of a residual limb, a distal end configured to reach across a distal end of the residual limb, a peripheral shoulder within the socket, an interior periphery reaching from the shoulder to the distal end, and an enlarged interior periphery reaching from the shoulder to the open proximal end;
- a sealing sleeve received within the enlarged interior periphery of the socket;
- and
- a ring-shaped inner brim received within the enlarged interior periphery of the socket between the residual limb and the sealing sleeve, whereby the inner brim seals the sealing sleeve against the socket within the enlarged interior periphery of the socket.
