Abstract

A wound dressing system comprising a wrap and a frangible ampoule is provided. The wrap is configured to contact/surround a wound site and includes an oxygen catalyst. The ampoule includes an oxygen precursor. The catalyst and precursor are configured to form oxygen when combined. A wound dressing system including a container is also provided that includes a powder, wrap, and frangible ampoule. The powder is disposed within the container, which is configured to allow the powder to be dispersed onto a wound site when activated. The wrap, which may include an oxygen catalyst, is also disposed in the container and is configured to contact/surround the wound site. The ampoule, also disposed in the container, includes a liquid containing an oxygen precursor. The liquid is configured to contact the wrap when the container is activated. Further, the catalyst and precursor are configured to form oxygen when combined.

First claim

What is claimed is:

1. A wound dressing system comprising:
a canister;
a powder disposed within the canister, wherein the canister is configured to allow the powder to be dispersed onto a wound site when the canister is activated; wherein activating the canister comprises squeezing or compressing the canister; a wrap disposed in the canister and separated from the powder, wherein the wrap is configured to contact or surround the wound site;
an oxygen catalyst; and
a frangible ampoule disposed in the canister and including a liquid containing an oxygen precursor, wherein the liquid is configured to contact the wrap upon activation of the canister, wherein the oxygen catalyst and the oxygen precursor are configured to form oxygen when combined.

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

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

4. The system of claim 1 , wherein the wrap includes an inner absorbent layer, wherein the inner absorbent layer is positioned adjacent the wound site when the wrap is applied to the wound site, further wherein the wrap includes an outer protective layer.

5. The system of claim 1 , wherein the wrap includes an elastic layer, a breathable barrier layer, or a combination thereof.

6. The system of claim 1 , wherein an end of the wrap includes an adhesive.

7. The system of claim 1 , wherein the wrap is a nonwoven composite.

8. The system of claim 1 , wherein the wrap includes the oxygen catalyst.

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

10. The system of claim 9 , wherein the peroxide is hydrogen peroxide, mannitol peroxide, urea peroxide, or an organic peroxide.

11. 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.

12. The system of claim 11 , wherein the nanoparticle metal is nanoparticle silver.

13. A method of applying a wound dressing system to a would site, the wound dressing system comprising a bioactive powder, a bioactive liquid, and a wrap, wherein the bioactive powder, the bioactive liquid, and the wrap are disposed within a container, the method comprising the steps of:
squeezing or compressing the container to activate the container to disperse the bioactive powder onto the wound site, wherein the step of squeezing or compressing the container compresses a frangible ampoule inside the container to disperse the bioactive liquid;
allowing sufficient time for the wrap to absorb the bioactive liquid, wherein the bioactive liquid includes an oxygen precursor and the wrap includes an oxygen catalyst, wherein oxygen is formed when the bioactive liquid contacts wrap; and
wrapping the wrap around the wound site.
