ABSTRACT:
Apparatus for applying a pressure waveform to a patient's limb for augmenting venous blood flow in the limb comprises: a sleeve means adapted to position onto a limb and apply a pressure to the limb near a pressure corresponding to a sleeve pressure signal; pressure transducing means for producing an applied pressure signal indicative of the pressure applied to the limb by the sleeve means; waveform register means for producing a reference pressure waveform signal indicative of a reference pressure waveform during a predetermined cycle time period, wherein the amplitude of the reference pressure waveform signal at any instant within the cycle time period is indicative of the amplitude of the reference pressure waveform at the instant and wherein the shape of the reference pressure waveform during a predetermined time interval within the cycle time period is adapted to augment the flow of venous blood into the limb proximal to the sleeve means from the limb beneath the sleeve means during the interval; and pressure waveform application means responsive to the applied pressure signal and the reference pressure waveform signal and operable by producing the sleeve pressure signal to maintain the difference between the pressure indicated by the applied pressure signal and the pressure indicated by the reference pressure waveform signal at less than a predetermined pressure difference at any instant within the cycle time period.
