Prosthetic socket liner

摘要

A prosthetic socket liner. A liner of the prosthetic socket liner has an inner and outer surface, the inner surface configured to engage skin of a user's residual limb and the outer surface configured to engage a surface of a socket of a prosthesis. An air channel coupled to the liner and to a valve extends downwardly towards a closed end of the liner and is configured to transfer air between an outer surface of the liner and ambient air through the valve. In implementations the air channel is configured to channel air between an inside of a cavity and a location outside the cavity. A method of donning a socket of a prosthesis includes donning a liner of a prosthetic socket liner over a residual limb, opening a valve on the liner, inserting the liner into a socket of a prosthesis with the valve open, and closing the valve.

主权项

1. A prosthetic socket liner, comprising:
a liner comprising an inner surface and an outer surface and one or more valves, the inner surface configured to engage with skin of a residual limb of a user and the outer surface configured to engage a surface of a socket of a prosthesis; and one or more air channels coupled to the one or more valves and comprised within a sidewall between the inner surface and outer surface of the liner, the one or more air channels extending downwardly towards a closed end of the liner, the one or more air channels configured to transfer air located between the outer surface of the liner and the surface of the socket with ambient air through the one or more valves; wherein the one or more valves comprise a selective two-way valve and wherein the outer surface of the liner is non-air-permeable.
