1. 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 a patient'"'"'s limb, said sleeve having a plurality of sets of adjoining, laterally extending fluid pressure chambers, each set consisting of an upper chamber and a lower chamber, said sets being progressively arranged longitudinally along the sleeve from a lower portion of the limb proximal the patient'"'"'s heart, relative to said lower portion;
means in said sleeve defining an opening between the adjacent upper and lower chambers of each set of chambers, each said upper chamber being otherwise closed to ingress and egress of fluid;
a plurality of conduits separately communicating with only the lower chambers of each of said sets of chambers;
means for intermittently inflating and deflating each of the lower chambers, only through said conduits, and thus said upper chambers, only through said opening means; and
means for maintaining the opening means in said chamber sets in an open configuration comprising a piece of open cell foam positioned in and extending entirely through said openings, said foam extending from the lower to the upper chamber in each set, whereby, upon application of fluid under pressure through a selected conduit to its associated lower chamber, sequential inflation of the selected lower and upper chambers occurs with inflation of the lower chamber being initiated first and the upper chamber thereafter, only through the opening means between the selected chambers, and initiation of deflation of said chambers also occurs sequentially with initiation of deflation of the selected lower chamber occurring first and the upper chamber thereafter, only through the opening means between the selected chambers.

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.
