ABSTRACT:
An apparatus to assist leg venous and skin circulation is provided and comprises a stocking which is secured around at least a portion of a leg of a person. The stocking includes a plurality of elongated and flexible tubular members so that each member defines an elongated and expandable fluid chamber. The stocking is arranged so that each fluid chamber extends substantially circumferentially around the person's leg and the members are axially adjacent each other. The apparatus further comprises an air distributor for sequentially fluidly pressurizing the chambers, maintained the pressure in each chamber for a predetermined period and thereafter exhausting the fluid pressure from the chambers. The air distributor performs this pressurization of the chambers in the stocking sequentially in a cephalad direction to thereby propel the leg venous blood towards the heart.
