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; and

at least two compartments within the housing separated by a divider cuff configured to seal 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.

11. The device of claim 7, 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.

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

8. A wound treatment device, comprising:

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

a plurality of separate compartments within the housing divided by a plurality of inflatable divider cuffs configured to seal against the limb, wherein each of the inflatable divider cuffs is coupled to a valve for inflation.

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.

13. A wound treatment device, comprising:

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

at least two compartments separated by an inflatable divider cuff having an opening for receiving a limb, wherein the housing is configured for at least one treatment selected from hyperbaric gas treatment, sequential compression treatment, and evacuation treatment.

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.
