Abstract
A prosthetic system includes a liner adapted to receive a residual limb and including an outer surface defining an outlet, and a socket including an interior surface and including an aperture extending from the interior surface to an external atmosphere. A first sealed volume is defined between a first portion of the outer surface of the liner and a first portion of the interior surface of the socket. A second sealed volume is defined between a second portion of the outer surface of the liner and a second portion of the interior surface of the socket. The first sealed volume is fluidly connected to the outer of the liner, fluidly separated from the second sealed volume by a seal element, and is independent from the second sealed volume throughout use of the system.
Claims24
A prosthetic system comprising:
- a liner adapted to receive a residual limb therein, the liner having a liner body formed from an elastomeric material, the liner body defining:
- a proximal end having an open configuration;
- a distal end having a closed configuration;
- and
- an inner surface and an outer surface opposite the inner surface, the outer surface including a first portion defining an outlet in communication with the inner surface, and a second portion including a first seal element and defining an inlet proximal to the first seal element in communication with the inner surface;
- a socket including an interior surface defining a socket cavity and including an aperture extending from the interior surface to an external atmosphere;
- a first sealed volume defined between the first portion of the outer surface of the liner and a first portion of the interior surface of the socket;
- and
- a second sealed volume defined distal to the first seal element between the second portion of the outer surface of the liner and a second portion of the interior surface of the socket, wherein the first sealed volume is fluidly connected to the outlet of the liner body, fluidly separated from the second sealed volume by a second seal element, and is independent from the second sealed volume throughout use of the system.
