Abstract

In an embodiment of the present invention, a wound treatment device can include a rigid housing having a housing wall with a first end and a second end forming a chamber therebetween. The device can further include an inflatable cuff releasably coupled to the housing wall at the first end. The housing wall can include a sidewall having an opening, a cover for closing the opening, and a clamp for releasably fastening the cover to the sidewall surrounding the opening.

Claims

1. A wound treatment device, comprising:

a rigid housing having a housing wall with a first end and a second end forming a chamber therebetween, and a sidewall having an opening;

an inflatable cuff releasably coupled to the housing wall at the first end;

a cover for closing the opening; and

a cam mechanism for releasably fastening the cover to the sidewall surrounding the opening, wherein the cam mechanism comprises;

a cam having a flat surface;

a swivel rod disposed within the cam for coupling with the housing; and

a handle for rotating the cam.

2. The device of claim 1, wherein the cuff is either partially or wholly inside the housing.

3. The device of claim 1, wherein the cuff is wholly external to the housing.

4. The device of claim 1, wherein the cover is transparent.

5. The device of claim 1, wherein the inflatable cuff includes an outer wall, an inner wall and a sidewall coupling the inner and outer walls, thereby forming a cuff interior in fluid communication with an inflating gas source.

6. The device of claim 1, wherein the inflatable cuff includes a valve in fluid communication with an inflating gas source.

7. A wound treatment device, comprising:

a rigid housing having a housing wall with a first end and a second end forming a chamber therebetween;

an inflatable cuff releasably coupled to the housing wall at the first end; and

an end cap coupled to the housing wall at the second end having a semispherical body extending out of the chamber.

8. The device of claim 7, wherein the cuff is either partially or wholly inside the housing.

9. The device of claim 7, wherein the cuff is wholly external to the housing.

10. A rigid wound treatment device, comprising:

a cylindrical wall having spaced apart ends forming a chamber therebetween; and

an inflatable cuff releasably coupled to one of the ends and extending in the chamber.

11. The device of claim 10, wherein the wall includes an access port on a side of the wall.

12. The device of claim 11, further comprising an access port cover releasably coupled to the access port.

13. The device of claim 12, wherein the access port cover includes at least one arcuate side having a first end having a first radius from a center of the cover, and a second end having a second radius from the center, wherein the first radius is smaller than the second radius.

14. The device of claim 13, wherein the cover includes a slot near the second end of the arcuate side.

15. The device of claim 12, wherein the access port cover is transparent.

16. The device of claim 12, wherein the access port is configured with a clamp for releasably attaching the access port cover thereto.

17. The device of claim 10, wherein a second end of the wall is releasably coupled to an end cap.

18. The device of claim 17, wherein the end cap has a central opening.

19. The device of claim 17, wherein the end cap couples to a flexible sleeve for hermetically sealing the device against the limb.

20. The device of claim 19, wherein the sleeve is inflatable.

21. The device of claim 19, wherein the flexible sleeve has a first portion that couples to the end cap and a second portion that seals against the limb.

22. The device of claim 21, wherein the second portion is inflatable.

23. The device of claim 21, wherein the second portion has a valve for coupling to an inflating means.

24. The device of claim 21, wherein the second portion has an outer wall, an inner wall, a sidewall that engages the outer and inner walls, and a valve for accommodating a fluid to inflate the second portion.

25. The device of claim 24, wherein the outer wall and sidewall are more rigid than the inner wall.

26. The device of claim 24, wherein the inner wall expands toward the limb upon the second portion being inflated.

27. The device of claim 21, wherein the first portion has a flexible lip that engages a groove disposed on an inside surface of the end cap.
