Abstract

A compression device comprising, a sleeve for placement about a patient'"'"'s limb, with the sleeve having an inflatable chamber. The device has a pump communicating with the chamber for inflating the chamber, and a bladder having an inflatable cavity communicating with the pump. The effective volume of the bladder cavity which communicated with the pump may be adjusted by a suitable device.

Claims

1. A compression device, comprising:

a sleeve for placement about a patient'"'"'s limb, said sleeve having an inflatable chamber;

a pump communicating with said chamber for inflating the chamber;

a bladder having an inflatable cavity communicating directly with the pump; and

means for adjusting the effective volume of said bladder cavity which communicates with said pump.

2. The device of claim 1 wherein said pump comprises a bellows.

3. The device of claim 1 including a conduit communicating between said pump and sleeve.

4. The device of claim 1 including a conduit communicating between said pump and bladder.

5. The device of claim 1 wherein said bladder has a pair of opposed flexible walls defining said cavity.

6. The device of claim 5 wherein the adjusting means comprises means for clamping said walls together laterally across the bladder, with the clamping means being movable longitudinally along the bladder.

7. The device of claim 6 wherein the clamping means comprises a pair of aligned rollers, and means for supporting the rollers in a closely spaced relationship with said walls located between the rollers and with the walls contacting each other between the rollers.

8. The device of claim 7 wherein the supporting means rotatably supports said rollers.

9. The device of claim 1 wherein said sleeve has a plurality of spaced inflatable fingers extending toward opposed ends of the sleeve.

10. The device of claim 1 wherein said sleeve includes a sheet of relatively inextensible material secured to a back portion of the sleeve, said sheet having means for securing the sheet about the patient'"'"'s limb.

11. The device of claim 1 wherein said pump sequentially inflates and deflates said sleeve.

12. The device of claim 11 wherein said pump is manually operable to inflate and deflate said sleeve.
