Abstract

Systems, methods, and kits for deep vein thrombosis prophylaxis.

Claims

1. A system for deep vein thrombosis prophylaxis, the system comprising:

a compression device configured to apply pressure to a skin surface of a patient;

a coupling mechanism configured to couple the compression device to a patient; and

a portable energy source coupled to the compression device, wherein the portable energy source is configured to supply energy to the compression device.

2. The system of claim 1 wherein the compression device is configured to exert a compressive force on the patient during use.

3. The system of claim 2 wherein the compression device is configured to exert a cyclic compressive force on the patient during use.

4. The system of claim 1 wherein the compression device comprises a pneumatic-actuated bladder.

5. The system of claim 4 wherein during use the pneumatic-actuated bladder is configured to expand and exert a compressive force on the patient.

6. The system of claim 1 wherein the compression device comprises a shape memory alloy.

7. The system of claim 6 wherein during use the shape memory alloy is configured to change shape when portable energy source is energized.

8. The system of claim 6 wherein the shape memory alloy is integrated in the coupling mechanism.

9. The system of claim 1 wherein the compression device comprises mechanical rollers.

10. The system of claim 9 wherein the mechanical rollers are eccentric mechanical rollers.

11. The system of claim 1 wherein the compression device comprises mechanical pinchers.

12. The system of claim 1 wherein the compression device comprises an ultrasonic emitter.

13. The system of claim 1 wherein the portable energy source comprises a rechargeable battery.

14. The system of claim 1 wherein the portable energy source comprises a rechargeable battery pack configured to be worn on a belt of a patient.

15. The system of claim 1 wherein the coupling mechanism comprises an elastic sleeve or band.

16. The system of claim 1 wherein the coupling mechanism comprises an elastic boot.

17. The system of claim 1 wherein the coupling mechanism is configured to couple the compression device to the leg of the patient.

18. The system of claim 1 wherein the coupling mechanism is configured to couple the compression device to the calf or thigh of the patient.

19. A method of preventing deep vein thrombosis in a patient, the method comprising:

providing a system according to any of the preceding claims;

coupling the compression device to the patient;

supplying energy to the compression device from the portable energy source; and

applying a compressive force to the patient from compression device.

20. The method of claim 19 wherein the compressive force is applied cyclically.
