Abstract

A vacuum bandage is provided for use with a wound having a wound surface. The bandage is connectable to a vacuum source and includes a wound dressing member having a wound contacting surface, a top surface, and a port configured for communication with the vacuum source. The wound dressing member further includes holes in the wound contacting surface configured for communication with the wound surface of the wound and a passageway between the port and each hole. The vacuum bandage further includes a pack adjacent to the top surface of the member. The pack may include an aperture positioned about the port.

Claims

1. A vacuum bandage connectable to a vacuum source and provided for use with a wound having a wound surface, the bandage comprising:

a wound dressing member having a wound contacting surface, a top surface, a port configured for communication with the vacuum source, holes in the wound contacting surface configured for communication with a wound surface of the wound, and a passageway between the port and each hole, and

a pack adjacent to the top surface of the member, the pack including an aperture positioned about the port.

2. The bandage of claim 1, wherein the pack includes a bottom surface, a top surface, a side wall extending from the top surface to the bottom surface, and a slit in communication with the aperture and extending from the top surface to the bottom surface and from the aperture to the side wall.

3. The bandage of claim 2, wherein the pack is an opened-cell foam.

4. The bandage of claim 2, wherein the pack is a closed-cell foam.

5. The bandage of claim 1, wherein the pack further includes an adhesive layer to attach the pack to the top surface of the wound dressing member.

6. The bandage of claim 1, wherein the pack is removably coupled to the member.

7. The bandage of claim 1, wherein the member further includes a connecter coupled to a top surface of the member and in communication with the port of the member, and wherein the connecter is disposed in the aperture of the pack.

8. The bandage of claim 5, wherein the member is generally noncompressible and the pack is generally compressible.

9. The bandage of claim 8, wherein the member is made of a medical grade silicone and the pack comprises foam.

10. The bandage of claim 5, wherein the pack is removable from the member while the member remains coupled to the vacuum source.

12. The vacuum bandage of claim 1, wherein the wound dressing member includes an anti-microbial.

13. The vacuum bandage of claim 12, wherein the anti-microbial includes silver ions.

11. A vacuum bandage for use with a wound having an open wound surface and configured to be coupled to a vacuum source, the bandage comprising:
