Abstract: The conformable convection liner is for use with a prosthetic system and configured to be donned over a residual limb of an amputee. The conformable convection liner includes a tubular body formed from an elastomeric limb-conforming material and including an outer surface and inner surface extending between a proximal end and a distal end thereof. A seal area is defined at the proximal end of the tubular body on the inner surface thereof. An outlet port is positioned at the distal end of the tubular body between the inner and outer surfaces thereof. An inner regulated environment is defined between the inner surface of the tubular body and the residual limb, the inner regulated environment extending between the proximal end of the tubular body with the seal area and the distal end of the tubular body with the outlet port.

Abstract: The forced convection system defines an outer regulated airflow environment between the socket and the liner, and an airflow generation device is coupled to the outer regulated airflow environment and configured to generate airflow therein. A convection control system includes convection control circuitry and is configured to adjust the airflow generation device and configured to dynamically control airflow within the outer regulated airflow environment to maintain negative gauge pressure therein and transfer thermal energy therein to an external atmosphere. The convection control system further includes a rising edge triggered negative gauge pressure regulation device including pressure control circuitry and an associated valve configured to control the first airflow proportioning device to open airflow paths to outer regulated airflow environment.

Abstract: The negative gauge pressure dynamic convection system for artificial limb system is to be attached to a residual limb of an amputee. The device provides thermal energy transfer from within an artificial limb to the ambient atmosphere through regulated cyclical differential pressure airflow into the sealed environment between both the residuum and the inside of the suspension liner of an artificial limb and as an alternate embodiment between the rigid socket and the outside of the suspension liner or a combination of both.
