Abstract

A hyperbaric oxygen device and methods of applying hyperbaric oxygen are disclosed. The device comprises an enclosure including a collapsible bag defined by two sheets of fluid impervious material sealed together at both ends such that gas can be delivered between the sheets to inflate the enclosure to a rigid state and maintain the enclosure in the rigid state when oxygen pressure in the interior of the enclosure is cycled between ambient pressure and above ambient pressure.

Claims

1. A topical hyperbaric device for delivering oxygen to an extremity of a patient comprising:

an enclosure including an interior and an exterior, the enclosure closed on one end and open on the other end and sized and shaped to receive the patient'"'"'s extremity, the enclosure defined by collapsible bag including two sheets of fluid impervious material sealed together at both ends, a first side of one sheet defining the exterior of the enclosure, a first side of the other sheet defining the interior of the enclosure such that gas can be delivered between the sheets to inflate and maintain the enclosure in a substantially rigid condition when oxygen pressure in the interior of the enclosure is cycled between first and second pressures.

2. The hyperbaric device of claim 1, further comprising a seal proximate the open end of the enclosure adapted to establish contact between the patient'"'"'s extremity to prevent oxygen from escaping from the enclosure.

3. The hyperbaric device of claim 2, wherein the seal comprises an inflatable cuff.

4. The hyperbaric device of claim 3, wherein the inflatable cuff is formed integrally with the enclosure.

5. The hyperbaric device of claim 4, wherein the inflatable cuff is defined by at least two sheets of material.

6. The hyperbaric device of claim 1, wherein the seal comprises a strap.

7. The hyperbaric device of claim 6, wherein the strap includes an adhesive portion.

8. The hyperbaric device of claim 1, further comprising a plurality of pockets formed between the two sheets.

9. The hyperbaric device of claim 8, wherein the pockets are interconnected.

10. The hyperbaric device of claim 9, wherein the pockets are formed by securing portions of the sheets of material together.

11. The hyperbaric device of claim 1, further comprising an inflatable pillow contained with the interior of the enclosure.

12. The hyperbaric device of claim 11, wherein the pillow is formed integrally with one of the sheets of material.

13. The hyperbaric device of claim 1, wherein the sheets of material are a resinous material.

14. The hyperbaric device of claim 13, wherein the resinous material includes polyethylene.

15. The hyperbaric device of claim 5, further comprising a plurality of interconnected pockets formed between the sheets.

16. The hyperbaric device of claim 15, further comprising a first fluid port in communication with the cuff.

17. The hyperbaric device of claim 16, further comprising a second fluid port in communication with the interconnected pockets.

18. The hyperbaric device of claim 17, further comprising a third fluid port in communication with the interior of the enclosure.

19. The hyperbaric device of claim 18, wherein the fluid ports are connected to a gas supply.

20. The hyperbaric device of claim 19, wherein the fluid ports are connected to a controller for regulating the pressure of gas.

22. The topical hyperbaric device of claim 20, wherein the means for retaining the collapsible bag in a rigid state includes a plurality of inflatable miniature chambers located on the exterior of the main chamber.

21. A topical hyperbaric device comprising:

a main chamber defined by a collapsible bag comprising a sheet of fluid impervious material, the bag being sealed on a first end and open on a second end, the main chamber sized and shaped to enclose a patient'"'"'s extremity;

an inflatable cuff proximate the open end of the chamber for sealing the main chamber around the patient'"'"'s extremity; and

means for retaining the collapsible bag in a rigid state when gas is cycled between first and second pressures such that the interior of the main chamber does not contact the patient'"'"'s extremity.

23. A method of treating an extremity of a patient with hyperbaric oxygen comprising:

placing a collapsible bag having an open end and a closed end in a substantially rigid state defining a chamber adapted to receive a patients extremity;

inserting a patient'"'"'s extremity through the open end of the chamber;

sealing the chamber around the patient'"'"'s extremity to prevent gas delivered to the interior of the chamber from escaping; and

delivering oxygen to the interior of the chamber in a pulsed manner between first and second pressures, wherein the bag remains in a substantially rigid state and does not collapse around the patient'"'"'s extremity.

24. The method of claim 23, wherein the collapsible bag comprises a double-layer of fluid impervious material including a space therebetween.

25. The method of claim 24, further comprising delivering a gas between the sheets of material to place the bag in a rigid state.

26. The method of claim 25, wherein a plurality of interconnected pockets are formed between the sheets of material.

27. The method of claim 26, wherein sealing the chamber around the patient'"'"'s extremity includes inflating an inflatable cuff located proximate the open end of the bag.

28. The method of claim 26, wherein sealing the chamber around the patient'"'"'s extremity includes wrapping an integral strap around the patients leg.
