Abstract
A liner defines a pouch, an opening, a cup, and a first ring positioned on the pouch distal to the opening. The pouch is air-permeable and defines an internal volume for receiving a residual limb. The opening defined by the pouch provides access to the internal volume. The cup is air-impermeable and is positioned on the pouch distal to the opening. The liner is combined with an adapter for connecting a residual limb to a prosthetic limb. The adapter has a socket for receiving the cup, at least one hole positioned within the socket for drainage therefrom and sleeve extending from the socket and surrounding a central space. The adapter also has at least one vent positioned in the sleeve and overlies the air permeable material.
