Abstract

An apparatus for stimulating healing of a wound, includes a porous pad adapted to contact a surface of the wound on an affected part of a body. An envelope for receiving the porous pad and the affected part of the body is provided, and the envelope includes a re-sealable opening that permits the wound to be inspected. A connector is fluidly connected to an interior of the envelope and to a source of negative pressure.

First claim

We claim:

1. An apparatus for stimulating healing of a wound, the apparatus comprising:
a porous pad adapted to contact a surface of the wound on an affected part of a body;
an envelope encompassing the porous pad and adapted to receive the affected part of the body; and
a connector fluidly connected to an interior of the envelope and adapted to be connected to a source of negative pressure and a source of irrigation.

2. The apparatus as claimed in claim 1 , wherein the source of negative pressure is a suction pump.

3. The apparatus as claimed in claim 1 , wherein the source of negative pressure is positioned outside the envelope.

4. The apparatus as claimed in claim 1 , wherein the envelope is formed from a cover that is air impermeable.

5. The apparatus as claimed in claim 1 , wherein the porous pad comprises a foam having intercommunicating cells.

6. The apparatus as claimed in claim 1 , wherein the envelope comprises a flexible plastic cover.

7. The apparatus as claimed in claim 1 , wherein the porous pad comprises a polyurethane foam.

8. The apparatus as claimed in claim 1 , wherein the porous pad comprises a lower base, a middle section, and an upper section.

9. The apparatus as claimed in claim 1 , wherein the porous pad is glove- or mitten-shaped to receive a hand of the body, the porous pad further comprising:
a lower base and an upper section forming a cavity to receive the hand; and
a middle section positioned within the cavity and including at least one finger-separator for positioning the hand within the cavity.

10. The apparatus as claimed in claim 9 , further comprising a V-cut type groove positioned on the at least one finger-separator.

11. The apparatus as claimed in claim 9 , wherein the envelope is substantially air-tight and further comprises:
a first opening that permits the wound to be inspected, the first opening being re-sealable; and
a second opening through which the hand of the body may be introduced, the second opening being capable of being sealed to a wrist or lower arm of the body.

12. The apparatus as claimed in claim 9 , wherein the lower base is connected to the upper section.

13. The apparatus as claimed in claim 9 , wherein the porous pad comprises a glove, a sock, or a sleeve.

14. The apparatus of claim 1 , wherein the connector is adapted to be fluidly coupled to a canister for collecting wound exudate.

15. The apparatus of claim 14 , wherein the canister is located between the porous pad and the source of negative pressure.

16. An apparatus for stimulating healing of a wound, the apparatus comprising:
a porous pad adapted to contact a surface of the wound on an affected part of a body;
an envelope encompassing the porous pad adapted to contact the surface of the wound on the affected part of the body; and
a connection means for connecting an interior of the envelope to a source of negative pressure and a source of fluid.

17. The apparatus as claimed in claim 16 , wherein the connection means comprises a flange bonded to the envelope, a spout, and an aperture.

18. The apparatus as claimed in claim 16 , wherein the source of negative pressure is positioned outside the envelope and is fluidly connected to the connection means.

19. The apparatus as claimed in claim 16 , wherein the porous pad is glove- or mitten-shaped to receive a hand of the body, the porous pad further comprising:
a lower base and an upper section forming a cavity to receive the hand; and
a middle section positioned within the cavity and including at least one finger-separator for positioning the hand within the cavity.

20. The apparatus as claimed in claim 19 , wherein the envelope is substantially air-tight and further comprises:
a first opening that permits the wound to be inspected, the first opening being re-sealable; and
a second opening through which the hand of the body may be introduced, the second opening being capable of being sealed to a wrist or lower arm of the body.

21. The apparatus of claim 16 , wherein the connector is adapted to be fluidly coupled to a canister for collecting wound exudate.

22. The apparatus of claim 21 , wherein the canister is located between the porous pad and the source of negative pressure.
