Abstract

A composite wound dressing and delivery apparatus includes a substantially transparent dressing layer having a lower surface that is coated with a pressure sensitive for applying the dressing layer over a wound to define a reservoir in which a negative pressure may be maintained. A substantially transparent backing layer adhered to the lower surface of the dressing layer in a releasable manner, and a vacuum port is centrally located on the dressing layer. The vacuum port is adapted to provide fluid communication between a vacuum source and the reservoir through the dressing layer. A targeting grid associated with either the dressing layer or the backing layer includes regularly spaced reference marks along at least two axes extending from the vacuum port.

Claims

1. A wound therapy kit comprising:

a wound dressing comprising a dressing layer configured for placement over a wound, and a backing layer adhered to the dressing layer in a releasable manner; and

a patch configured to be secured to the dressing layer, the patch comprising;

a patch layer configured to prevent leaks,

a patch backing layer adhered to the patch layer, the patch backing layer configured to be removed from an underside of the patch layer,

a patch delivery layer adhered to the patch layer, the patch delivery layer configured to be removed from a top surface of the patch layer,

a first identifier disposed on any of the patch layer, the patch backing layer, or the patch delivery layer, and

a second identifier disposed on any of the patch layer or the patch delivery layer.

2. The therapy kit according to claim 1, further comprising at least one of a wound filler adapted for placement in the wound and a wound contact layer adapted for placement in contact with the wound.

3. The therapy kit according to claim 1, further comprising a canister adapted to collect wound exudates.

4. The therapy kit according to claim 1, wherein the dressing layer comprises a vacuum port.

5. The therapy kit according to claim 4, further comprising a fluid conduit configured to be attached to the vacuum port.

6. The therapy kit according to claim 4, wherein the patch layer comprises an opening configured to substantially surround the vacuum port.

7. The therapy kit according to claim 1, wherein the patch layer is flexible.

8. The therapy kit according to claim 1, wherein the patch layer is substantially round.

9. The therapy kit according to claim 1, wherein the patch layer is substantially elongate.

10. The therapy kit according to claim 1, wherein the patch backing layer configured to expose an adhesive coating on an underside of the patch layer when the patch backing layer is removed.

11. A wound therapy kit comprising:

a wound dressing comprising a dressing layer configured for placement over a wound, and a backing layer adhered to the dressing layer in a releasable manner; and

a patch configured to be secured to the dressing layer, the patch comprising;

a patch layer configured to prevent leaks,

a patch backing layer adhered to the patch layer,

a patch delivery layer adhered to the patch layer,

a first identifier disposed on any of the patch layer, the patch backing layer, or the patch delivery layer, and

a second identifier disposed on any of the patch layer or the patch delivery layer,

wherein the first and second identifiers comprise indicia representative of an order of removal of the patch backing layer and the patch delivery layer from the patch layer.

12. The therapy kit according to claim 11, further comprising at least one of a wound filler adapted for placement in the wound and a wound contact layer adapted for placement in contact with the wound.

13. The therapy kit according to claim 11, further comprising a canister adapted to collect wound exudates.

14. The therapy kit according to claim 11, wherein the patch layer is flexible.

15. The therapy kit according to claim 11, wherein the patch layer is substantially round.

16. The therapy kit according to claim 11, wherein the patch layer is substantially elongate.

17. A wound therapy kit comprising:

a wound dressing comprising a dressing layer configured for placement over a wound, and a backing layer adhered to the dressing layer in a releasable manner;

a patch configured to be secured to the dressing layer, the patch comprising;

a patch layer configured to prevent leaks,

a patch backing layer adhered to the patch layer, and

a patch delivery layer adhered to the patch layer;

wherein the dressing layer comprises a vacuum port; and

wherein the patch layer comprises an opening configured to substantially surround the vacuum port.

18. The therapy kit according to claim 17, further comprising a fluid conduit configured to be attached to the vacuum port.
