Abstract

A wound therapy device and a kit for same with a housing material, a gasket disposed around at least a portion of the housing material, a non-woven absorption material, and a port. The gasket is sized and configured such that at least a first portion of the gasket will be adhered to a second portion of the gasket upon a folding of the housing material. A method of using a wound therapy device.

Claims (23)

1. A method of treating a wound on an appendage with negative pressure wound therapy comprising the steps of:

disposing a non-woven absorption material over the wound;

removing at least a portion of a liner from a housing material having a first side with an adhesive, a gasket disposed on the first side and a port in communication with the housing material;

positioning the housing material around the appendage;

folding the housing material to seal the housing material to the appendage such that a first portion of the gasket is adhered to a second portion of the gasket around at least a portion of a periphery of the appendage, wherein the non-woven absorption material is positioned within the seal formed by the gasket and the port is positioned adjacent the non-woven absorption material; and,

applying negative pressure to the wound through the port on the housing to apply negative pressure to the wound through the non-woven absorption material.

2. The method of claim 1 further comprising the step of:

disposing a wound interface layer in between the non-woven absorption material and the wound.

3. The method of claim 2 wherein the step of disposing the wound interface layer in between the non-woven absorption material and the wound includes the step of surrounding the non-woven absorption material with the wound interface layer.

4. The method of claim 1 further comprising the step of:

removing a second liner from the housing material.

5. The method of claim 1 further comprising the step of:

removing a stiffener from the housing material.

6. The method of claim 1 wherein the step of folding the housing material includes the step of folding a first portion of the housing material onto a second portion of the housing material.

7. The method of claim 1 wherein the step of folding the housing material includes folding the housing material in a direction that is perpendicular to a longitudinal axis of the appendage.

8. The method of claim 1 wherein the step of folding the housing material includes folding the housing material in a direction that is parallel to a longitudinal axis of the appendage.

9. The method of claim 1 wherein the step of removing at least a portion of a liner from a housing material includes removing all of the liner.

10. The method of claim 1 further comprising the step of collecting and retaining exudates within the non-woven absorption material.

11. The method of claim 1 further comprising the step of preventing exudates from flowing through the port.

12. The method of claim 1 wherein the step of sealing the housing material to the appendage includes a third portion of the gasket being adhered to a fourth portion of the gasket.

13. The method of claim 1 , wherein folding and sealing the housing material comprises folding the gasket such that a first area of the first portion of the gasket, when folded and sealed, is approximately equal to a second area of the second portion of the gasket.

14. The method of claim 1 , wherein removing at least a portion of a liner need not occur after disposing a non-woven absorption material over the wound.

15. The method of claim 1 , wherein the port passes through the housing.
