Abstract

A method of preparing a wound model. The method includes simulating a non-healing wound edge, simulating eschar, simulating a fibrin layer, simulating biofilm, and simulating foreign debris.

First claim

What is claimed is:

1. A method of preparing a wound model, the method comprising:
simulating a non-healing wound edge;
simulating eschar;
simulating a fibrin layer;
simulating biofilm; and
simulating foreign debris.

2. The method of claim 1 , further comprising:
creating a wound on a surface of a specimen.

3. The method of claim 2 , wherein simulating a non-healing wound edge comprises:
applying an orange dye to the surface of the specimen that is adjacent to the wound.

4. The method of claim 3 , further comprising:
simulating slough by applying orange dye to a wound bed of the wound.

5. The method of claim 2 , wherein simulating eschar comprises:
applying a black dye to a wound bed of the wound.

6. The method of claim 2 , wherein simulating the fibrin layer comprises:
applying a yellow dye to a wound bed of the wound.

7. The method of claim 2 , wherein simulating biofilm comprises:
applying a mixture comprising yellow orange dye, bright blue dye, yellow green dye, and a tissue adhesive to a wound bed of the wound.

8. The method of claim 7 , wherein the yellow orange dye, the bright blue dye, and the yellow green dye are microsphere dyes.

9. The method of claim 2 , wherein simulating foreign debris comprises:
introducing fabric pieces into the wound.

10. A method of preparing a wound model, the method comprising:
creating a wound on a surface of a specimen;
simulating a non-healing wound edge by applying an orange dye to the surface of the specimen that is adjacent to the wound;
simulating slough by applying orange dye to a wound bed of the wound;
simulating eschar by applying a black dye to the wound bed of the wound;
simulating a fibrin layer by applying a yellow dye to the wound bed of the wound;
simulating biofilm by applying a mixture comprising yellow orange dye, bright blue dye, yellow green dye, and a tissue adhesive to the wound bed of the wound; and
simulating foreign debris by introducing fabric pieces into the wound.
