Abstract

A limb wound treatment device is described having a first end, a second end and an interior therebetween for accommodating a treatment gas. The device can include a flexible housing that can be inflated or a rigid housing. The first end can include an inflatable cuff seal for hermetically sealing against the limb being treated. The second end can include a closed end or an access port that is releasably sealed with a clamping mechanism. Further, the device can include a controller that can inflate that housing, inflate the cuff seal and provide treatment gas to the interior, in response to pressures within the cuff seal and the housing. Further, the device can accommodate different types of wound treatments, such as hyperbaric therapy, compression therapy or negative pressure therapy.

Claims

1. A wound treatment device, comprising:

a housing having a closed end and an open end configured to seal against a limb, said housing defining an interior region for treatment of the limb;

at least two adjacent compartments formed within the interior region of the housing separated by a divider cuff, said at least two compartments in communication with one another by an opening in the divider cuff, said divider cuff configured to seal said opening against the limb for isolating said at least two compartments from one another within the interior region, said at least two compartments forming first and second treatment chambers within the housing each having an interior for receiving the limb; and

a seal adjacent said open end for sealing against the limb.

2. The device of claim 1, wherein the compartments have an interior space for separately accommodating the treatment of the limb.

3. The device of claim 1, wherein the divider cuff includes an inflatable space for receiving an inflation gas.

4. The device of claim 1, wherein the divider cuff includes a valve for communicating with a gas source.

5. The device of claim 1, wherein the divider cuff includes a first annular wall having a first opening, a second annular wall having a second opening, and a sidewall coupling together the first and second annular walls adjacent the first and second openings.

6. The device of claim 5, wherein a thickness of the first and second annular walls is greater than a thickness of the sidewall.

7. The device of claim 5, wherein the sidewall is adapted to form a seal against the limb of the patient.

8. A wound treatment device, comprising:

a housing having a closed end and an open end configured to seal against a limb, said housing defining an interior region for treatment of the limb;

a plurality of separate compartments within the interior region of said housing separated by a plurality of inflatable divider cuffs, said divider cuffs each having an opening for receiving the limb and configured to seal said opening against the limb for isolating said plurality of separate compartments from one another, whereby said compartments form separate treatment chambers within the housing for receiving the limb, and wherein each of the inflatable divider cuffs is coupled to a valve for inflation; and

a seal adjacent said open end for sealing against the limb.

9. The device of claim 8, wherein each of the plurality of compartments is in separate communication with a treatment gas source.

10. The device of claim 8, wherein each of the plurality of inflatable divider cuffs is in separate communication with an inflation gas source.

11. The device of claim 8, wherein the plurality of inflatable divider cuffs includes a first annular wall having a first opening, a second annular wall having a second opening, and a sidewall coupling together the first and second annular walls adjacent the first and second openings.

12. The device of claim 11, wherein a thickness of the first and second annular walls is greater than a thickness of the sidewall.

13. A wound treatment device, comprising:

a housing having a closed end and an open end configured to seal against a limb;

at least two separate limb treatment compartments in communication with one another within said housing separated by an inflatable divider cuff, said divider cuff having an opening for receiving a limb and adapted for sealing against the limb for isolating the limb treatment compartments from one another within the housing, wherein the at least two limb treatment compartments are configured for receiving the limb therein and for at least one treatment selected from the group consisting of hyperbaric gas treatment, sequential compression treatment, and evacuation treatment; and

a seal adjacent the open end for sealing against the limb.

14. The device of claim 13, further comprising an absorbent liner having a removable portion disposed within the housing.

15. The device of claim 13, wherein the inflatable divider cuff includes an inlet valve for supplying a gas to inflate the inflatable divider cuff.

16. The device of claim 13, wherein the housing includes an inlet valve for supplying treatment gas to at least one of the compartments.

17. The device of claim 13, wherein the housing includes a plurality of valves for supplying and removing treatment gas from the interior of the compartments.

18. The device of claim 13, wherein the divider cuff includes a first annular wall having a first opening, a second annular wall having a second opening, and a sidewall coupling together the first and second annular walls adjacent the first and second openings.

19. The device of claim 18, wherein a thickness of the first and second annular walls is greater than a thickness of the sidewall.

20. The device of claim 18, wherein the sidewall is adapted to form a seal against the limb of the patient.

21. A wound treatment device, comprising:

a flexible housing having a closed end and an open end, said housing defining an interior region for treatment of a limb, said open end including a cuff seal adjacent thereto for sealing against the limb;

at least one divider cuff having a cuff opening within the interior region of said housing spaced from said cuff seal defining first and second adjacent compartments in communication with one another through said cuff opening, said divider cuff having said cuff opening for receiving the limb extending between said first and second compartments, said divider cuff configured for sealing said cuff opening about the limb thereby isolating said first and second compartments from each other within the housing.

22. The device of claim 21, wherein said first and second compartments are separately adapted for treatment of said limb.

23. The device of claim 21, wherein said divider cuff is inflatable for sealing against a limb when extending through said cuff opening.

24. A wound treatment device, comprising:

a housing having a closed end and an open end configured to receive a limb, said housing defining an interior region for treatment of the limb;

a cuff seal adjacent the open end of the housing for sealing against the limb; and

at least one divider cuff having an opening for receiving the limb and arranged within the interior region of the housing between the closed end and the cuff seal, said divider cuff separating the interior region into two adjacent compartments in communication with one another through said opening, said divider cuff configured to seal said opening against the limb for isolating said two compartments from one another for treatment of the limb within an interior of said two compartments.

25. The device of claim 24, wherein said cuff seal and said divider cuff are inflatable.

26. The device of claim 25, wherein said housing is flexible.
