Abstract

A compression sleeve for applying compressive pressures against a patient'"'"'s limb from a source of pressurized fluid. The sleeve has a plurality of separate fluid pressure chambers arranged longitudinally along the sleeve, and a sizer portion located intermediate a pair of adjoining pressure chambers to permit adjustment of the sleeve to limbs of varying sizes. The sizer portion may comprise a ventilation chamber having a plurality of openings for ventilating the patient'"'"'s limb with air during use of the sleeve.

Claims

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 the patient'"'"'s limb, said sleeve having a plurality of separate fluid pressure chambers 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 said lower portion, said sleeve including flexible sizer means extending between a pair of adjoining chambers and having a sufficient length to permit adjustment of the sleeve on limbs of varying sizes between a first position with said adjoining chambers being spaced apart a relatively small distance and a second position with said adjoining chambers being spaced from each other a relatively large distance, said sizer means being uninflated during use of the device; and

means for intermittently inflating and deflating said compression chambers.

2. The device of claim 1 wherein said sleeve includes a set of contiguous lower and upper chambers, and in which the sizer means separates the lower and upper chamber sets.

3. The device of claim 2 wherein said lower set comprises four contiguous chambers, and said upper set comprises two contiguous chambers.

4. A sleeve for applying compressive pressures against a patient'"'"'s limb, comprising:

a pair of flexible sheets of fluid impervious material;

means for connecting said sheets together along lines defining a plurality of separate laterally extending inflatable chambers disposed longitudinally along the sleeve and defining a noninflatable sizer portion extending between a pair of adjoining chambers, said sizer portion having a sufficient length to permit adjustment of the sleeve on limbs of varying sizes between a first position with said adjoining chambers being spaced apart a relatively small distance and a second position with said adjoining chambers being spaced apart a relatively large distance; and

means for releasably securing the sleeve about the patient'"'"'s limb with said chambers and sizer portion encircling the limb.

5. 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, said sleeve having inner and outer flexible sheets defining a plurality of closed separate fluid pressure chambers arranged longitudinally along the sleeve, and a ventilation chamber separate from said pressure chambers having a plurality of openings for facing the patient'"'"'s limb; and

means for intermittently inflating and deflating said pressure chambers and for passing air into the ventilation chamber to ventilate the patient'"'"'s limb through said openings.

6. A sleeve for applying compressive pressures against a patient'"'"'s limb, comprising:

an inner flexible sheet of fluid impervious material;

an outer flexible sheet of fluid impervious material;

means for connecting said sheets together along lines defining a plurality of separate closed pressure chambers and a separate ventilation chamber between the sheets, said inner sheet having a plurality of openings communicating with the ventilation chamber to permit passage of air from the ventilation chamber onto the patient'"'"'s limb; and

means for releasably securing the sleeve about the patient'"'"'s limb with the chambers encircling the limb.
