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. 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 flexible housing having an interior for accommodating treatment gas, the housing having;

a first end for accommodating a patient'"'"'s limb; and

a second end remote from the first end having an access port; and

a clamping mechanism for sealing and unsealing the access port, the clamping mechanism comprises a first leg, a second leg coupled to the first leg, wherein the second leg is configured to pivotably move with respect to the first leg, a base on which are mounted the first and second legs, and a fastener for fastening the first and second legs together.

2. The device of claim 1, wherein the second end includes an elongated member about which the second end of the housing is coupled.

3. The device of claim 2, wherein the elongated member is enclosed in the clamping mechanism in a sealed state of the access port.

4. A wound treatment device for use with a clamping mechanism, comprising:

a flexible enclosure having a first end configured for sealing against a limb and a second end adapted to form an access port;

wherein the second end is coupled to an elongated member adapted for releasably coupling to a clamping mechanism for sealing and unsealing the access port, wherein the clamping mechanism comprises a first leg, a second leg coupled to the first leg, wherein the second leg is configured to pivotably move with respect to the first leg, a base on which are mounted the first and second legs, and a fastener for fastening the first and second legs together.

5. The device of claim 4, wherein at least one of the first and the second legs includes an indent for accommodating the elongated member.

6. The device of claim 4, wherein at least one of the first or second legs includes ports for fluid lines to provide treatment gas to the flexible enclosure.

7. The device of claim 4, wherein the fastener is coupled to a switch that stops or starts a flow of treatment gas to the flexible enclosure.

8. A wound treatment device, comprising:

a flexible enclosure, having an interior, comprising;

a first end configured for sealing against a limb;

a second end forming a sealable and unsealable access port; and

an elongated member about which the second end of the enclosure is coupled thereto, the second end of the elongated member adapted to be releasably coupled to a clamping mechanism comprising;

a first leg;

a second leg movable relative to the first leg;

an indent disposed on an inside surface of at least one of the first and the second legs to accommodate the elongated member and second end of the enclosure coupled thereto; and

a fastener for releasably coupling the first leg to the second leg with the elongated member therebetween.

9. The device of claim 8, further comprising a hinge for pivotably moving the first leg about the second leg.

10. The device of claim 8, further comprising a base on which the first and second legs are mounted.

11. The device of claim 8, wherein the flexible enclosure includes a first sheet and a second sheet.

12. The device of claim 11, wherein the first sheet includes the elongated member at the second end.

13. The device of claim 11, wherein the elongated member is fixedly attached to the first sheet.

14. The device of claim 11, wherein the first and second sheets are wrapped around the elongated member.

15. The device of claim 8, wherein the first leg has a first leg indent for accommodating the elongated member.

16. The device of claim 8, wherein the second leg has a second leg indent for accommodating the elongated member.

17. The device of claim 8, wherein at least one of the first or second legs includes ports for fluid lines to provide treatment gas to the flexible enclosure.
