Abstract

A bandage is provided for use with a wound having a wound surface. The bandage is connectable to a vacuum source and may include a flexible cover positioned over the wound and a collar coupled to the cover. The cover includes a port and is configured to seal to a patient'"'"'s healthy skin surrounding the wound. The collar may be coupled to the cover and include a passageway in communication with the port of the cover. The passageway is configured to receive at least a portion of a tube in communication with the vacuum source. The bandage may also include a sealer coupled to the collar. The sealer may be configured to provide a substantially airtight seal between the tube and the passageway to create a sealed environment capable of maintaining a negative pressure between the cover and the wound surface.

Claims

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

a flexible cover positioned over the wound and configured to seal to a patient'"'"'s healthy skin surrounding the wound, the cover including a port,

a collar coupled to the cover and including a passageway in communication with the port of the cover, the passageway being configured to receive at least a portion of a tube in communication with the vacuum source,

a sealer coupled to the collar and configured to provide a substantially airtight seal between the tube and the passageway to create a sealed environment capable of maintaining a negative pressure between the cover and the wound surface, and

a flexible member positioned to lie directly adjacent the wound surface, the member including a connector configured to receive the tube.

2. The bandage of claim 1, wherein the collar includes a disc portion coupled to the cover and a tube receiver coupled to the disc portion, and wherein the tube receiver extends away from the cover and includes the passageway in communication with the port of the cover.

3. The bandage of claim 2, wherein the tube receiver includes a narrow neck portion adjacent the disc portion.

4. The bandage of claim 3, wherein collar includes a slit formed through the tube receiver and the disc portion and extending outwardly from the passageway to an outer edge of the disc portion to define radially extending first and second surfaces, and wherein the collar is normally in a closed position, where first and second surfaces are adjacent each other and is moved to an opened position, where the first surface and the second surface are spaced apart from each other, to configure the collar to receive the tube at least in part into the passageway.

5. The bandage of claim 4, wherein the sealer is a pull-tab positioned around the neck portion and configured to be tightened around the neck portion to move the slit from the opened position to the closed position.

6. The bandage of claim 1, wherein the collar is coupled to a top surface of the cover.

7. A vacuum bandage connectable to a vacuum source for providing vacuum treatment to a wound having a wound surface, the vacuum bandage comprising

a synthetic flexible member positioned to lie directly adjacent the wound surface, the member including a connector configured to receive a vacuum tube to couple the tube to the member, the vacuum tube in communication with the vacuum source,

a thin, flexible cover positioned over the member and configured to seal to a patient'"'"'s healthy skin surrounding the wound, the cover including a port, and

a collar coupled to the cover and including a passageway in communication with the port of the cover, the passageway being configured to receive at least a portion of the vacuum tube in communication with the vacuum source or irrigation source, and the collar configured to permit the tube to be removed and replaced while the cover remains sealed to the patient'"'"'s healthy skin surrounding the wound.

8. The bandage of claim 7, wherein the collar includes a disc portion and a tube receiver coupled to the disc portion and including the passageway.

9. The bandage of claim 8, wherein the collar is coupled to the top surface of the cover.

10. The bandage of claim 7, ffirtber including a means for creating a generally airtight seal between the tube and the collar.

11. The bandage of claim 10, wherein the means is a pull-tab for placement around the passageway of the collar, the pull-tab is adjustable about the collar to increase and decrease the size of the passageway within in which the tube is at least in part received.

12. The bandage of claim 11, wherein the pull-tab includes a strap having ridges at one end and a strap retainer coupled to the other end and the ridged end is received through the strap retainer to create a loop around the collar.
