Hyperbaric wound treatment device

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.
