Abstract
A prosthetic system includes a prosthetic liner adapted to provide an interface between a residual limb and a prosthetic socket, and a valve assembly. The valve assembly is arranged for regulating fluid communication between an interface region defined between the prosthetic liner and the residual limb and a suspension chamber defined between the prosthetic liner and the prosthetic socket. A vacuum in the suspension chamber selectively moves the valve assembly between a closed position in which the valve assembly fluidly separates the suspension chamber from the interface region, and an open position in which a portion of the vacuum in the suspension chamber draws fluid from the interface region via the valve assembly into the suspension chamber.

A prosthetic system comprising:
- a prosthetic liner adapted to provide an interface between a residual limb and a prosthetic socket;
- and
- a valve assembly arranged for regulating fluid communication between an interface region defined between the prosthetic liner and the residual limb and a suspension chamber defined between the prosthetic liner and the prosthetic socket, wherein a vacuum in the suspension chamber selectively moves the valve assembly between a closed position in which the valve assembly fluidly separates the suspension chamber from the interface region, and an open position in which a portion of the vacuum in the suspension chamber draws fluid from the interface region via the valve assembly into the suspension chamber.
A prosthetic system comprising:
- a prosthetic socket;
- a prosthetic liner adapted to provide an interface between a residual limb and the prosthetic socket;
- and
- a valve assembly including a valve housing carrying a valve unit oriented in a transverse direction relative to a longitudinal axis of the prosthetic liner, the valve assembly attached to a distal end of the prosthetic liner and arranged for regulating fluid communication between an interface region defined between the prosthetic liner and the residual limb and a suspension chamber defined between the prosthetic liner and the prosthetic socket, wherein a vacuum in the suspension chamber selectively moves the valve assembly between a closed position in which the valve assembly fluidly separates the suspension chamber from the interface region, and an open position in which a portion of the vacuum in the suspension chamber draws fluid from the interface region via the valve assembly into the suspension chamber.
A prosthetic system comprising:
- a prosthetic socket;
- a prosthetic liner adapted to provide an interface between a residual limb and the prosthetic socket;
- a pump mechanism fluidly coupled to a suspension chamber defined between the prosthetic liner and the prosthetic socket;
- and
- a heat management system including:
- an aperture defined in a distal end of the prosthetic liner and connecting the suspension chamber and an interface region defined between the prosthetic liner and the residual limb;
- and
- a valve assembly positioned in the aperture and arranged for regulating fluid communication between the suspension chamber and the interface region, wherein a vacuum generated by the pump mechanism in the suspension chamber selectively moves the valve assembly between a closed position in which the valve assembly fluidly separates the suspension chamber from the interface region, and an open position in which a portion of the vacuum in the suspension chamber draws fluid from the interface region via the valve assembly into the suspension chamber.
