Foam wound inserts with regions of higher and lower densities, wound dressings, and methods
Foam wound inserts with high-density and low-density regions, methods for making wound inserts, wound-treatment methods, and wound-treatment systems.
1. A negative-pressure wound therapy system, comprising:
a foam insert having a high-density region configured to contact a wound, the high-density region compressed to a density between 1.2 and 4 times a pre-compression density of the high-density region; and
a drape configured to be placed over the foam insert and form a sealed space between the drape and the wound.
2. The system of claim 1 , wherein the high-density region forms a grid pattern.
3. The system of claim 1 , wherein the high-density region forms a pattern of rows.
4. The system of claim 1 , wherein the high-density region forms a pattern of rectangles.
5. The system of claim 1 , wherein the high-density region forms a pattern of rings.
6. The system of claim 1 , wherein the high-density region forms a checker-board pattern.
7. The system of claim 1 , wherein the high-density region is spiraled into a circular configuration.
8. The system of claim 1 , wherein the high-density region is configured to be torn from the foam insert.
