Abstract: A device for applying compressive pressures against a patient's limb from a source of pressurized fluid comprising, an elongated pressure sleeve for enclosing a length of the patient's limb. The sleeve has a plurality of sets of adjoining laterally extending fluid pressure chambers, with the sets being progressively arranged longitudinally along the sleeve from a lower portion of the limb to an upper portion of the limb proximal the patient's heart relative to the lower portion. The sleeve has an opening communicating between a lower and an upper chamber in each of the sets. The device has a plurality of conduits separately communicating with the lower chambers in each of the sets, and a device for intermittently inflating the chambers through the conduits and for intermittently deflating the chambers.
