Abstract

A wound dressing system that includes a conformal cover and an infusion pump is provided. The cover includes a fluid port and an oxygen catalyst. The infusion pump is configured to deliver a bioactive liquid to the cover via the fluid port. The liquid includes an oxygen precursor. Upon combination, the oxygen catalyst and precursor react to form oxygen. A method of applying a wound dressing system including a bioactive powder, a bioactive liquid, and a conformal cover to a wound site is also provided. The method includes applying the powder to the wound site; securing the cover around the wound site, where the cover includes an oxygen catalyst and a fluid port; and delivering the bioactive liquid to at least an inner layer of the cover via the fluid port, where the bioactive liquid includes an oxygen precursor.

First claim

What is claimed is:

1. A wound dressing system comprising:
a conformal cover, wherein the conformal cover comprises a multilayer material including an outer protective layer, an elastic layer, a breathable layer, and an inner absorbent layer, further wherein the conformal cover includes a fluid port and an oxygen catalyst;
a container having a powder dispenser and comprising a bioactive powder; and
an infusion pump configured to deliver a bioactive liquid to the conformal cover via the fluid port, wherein the bioactive liquid includes an oxygen precursor.

2. The system of claim 1 , wherein the conformal cover is configured to form a sleeve around the wound site.

3. The system of claim 1 , wherein the oxygen catalyst includes a nanoparticle metal, a carbonate, a copper compound, catalase, peroxidase, manganese dioxide, iodide, potassium iodine, or a combination thereof.

4. The system of claim 3 , wherein the nanoparticle metal is silver.

5. The system of claim 1 , wherein the bioactive liquid further includes a hemostatic agent, an antimicrobial agent, a biotoxin sequestrant, pain medication, a debridement agent, or a combination thereof.

6. The system of claim 1 , wherein the oxygen precursor includes a peroxide.

7. The system of claim 6 , wherein the peroxide includes hydrogen peroxide, mannitol peroxide, urea peroxide, an organic peroxide, or a combination thereof.

8. The system of claim 1 , wherein the oxygen catalyst and the oxygen precursor are configured to form oxygen when combined.

9. The system of claim 1 , wherein the bioactive powder includes a hemostatic agent, an antimicrobial agent, a biotoxin sequestrant, pain medication, a debridement agent, or a combination thereof.

10. The system of claim 1 , wherein the conformal cover is a nonwoven composite.

11. The system of claim 1 , wherein the inner absorbent layer is configured to be positioned adjacent the wound site when the conformal cover is positioned around the wound site.

12. The system of claim 1 , wherein the infusion pump is elastomeric.

13. A method of applying a wound dressing system comprising a container that includes a bioactive powder, a bioactive liquid, and a conformal cover to a wound site, the method comprising:
applying the bioactive powder to the wound site, wherein the bioactive powder is dispensed from the container via a powder dispenser;
securing the conformal cover around the wound site, wherein the conformal cover comprises a multilayer material including an outer protective layer, an elastic layer, a breathable layer, and an inner absorbent layer, further wherein the conformal cover includes an oxygen catalyst a fluid port; and
delivering the bioactive liquid to at least an inner layer of the conformal cover via the fluid port, wherein the bioactive liquid includes an oxygen precursor.

14. The method of claim 13 , wherein oxygen is formed when the oxygen precursor contacts the oxygen catalyst.

15. The method of claim 13 , wherein the oxygen precursor includes a peroxide.

16. The method of claim 13 , wherein the oxygen catalyst includes a nanoparticle metal, a carbonate, a copper compound, catalase, peroxidase, manganese dioxide, iodide, potassium iodine, or a combination thereof.

17. The method of claim 13 , wherein an infusion pump delivers the bioactive liquid to an interior of the conformal cover.
