ABSTRACT:
Blood circulation in an injured human foot is involuntarily promoted in a cuum over-pressure cycle and in synchronism with the human heart's systolic and diastolic pressure pulsations. In a preferred embodiment, the circulation enhancing apparatus comprises an air tight boot contoured to fit the injured human foot, a pressure modulator for providing over-pressure and vacuum pulses to the boot to enhance blood circulation through the injured foot and a control circuit which monitors the heart's systolic and diastolic pressure pulsations and provides electrical control signals to the pressure modulator to assure that the over-pressure and vacuum pulses are cyclic and in synchronism with the heart's systolic and diastolic pressure pulsations.
