ABSTRACT:
Venous blood flow in a non-ambulating human leg is involuntarily promoted in a repeating cycle of successively actuated venous pumps, in imitation of the pump-actuating sequence which characterizes normal walking. Specifically, in the preferred embodiment, the proximal calf pump and the distal calf pump are operated, in that sequential order, following a given operation of the foot pump and prior to the next successive operation of the foot pump.
