Expandable wound dressings
View Patent ↗A system for wound treatment includes adjunctive wound therapy devices and substrates comprising multiple first reservoirs and multiple second reservoirs. Selected ones of the multiple first reservoirs include a reducing agent, and first reservoir surfaces of selected ones of the multiple first reservoirs are proximate to a first substrate surface. Selected ones of the multiple second reservoirs include an oxidizing agent, and second reservoir surfaces of selected ones of the multiple second reservoirs are proximate to the first substrate surface.
1. A method of treating the skin, comprising applying a dressing comprising a substrate comprising biocompatible electrodes capable of generating at least one of a low level electric field (LLEF) or low level micro current (LLMC), wherein the substrate comprises at least one discontinuous region comprising at least one long axis, wherein said wound dressing is expandable perpendicular to said long axis.
2. The method of claim 1 , wherein the biocompatible electrodes comprise a first array comprising a pattern of microcells formed from a first conductive material, and a second array comprising a pattern of microcells formed from a second conductive material.
3. The method of claim 2 , wherein the first conductive material and the second conductive material comprise the same material.
4. The dressing of claim 3 , wherein the first and second array each comprise a discrete circuit.
5. The method of claim 4 , further comprising a power source.
6. The method of claim 2 , wherein the first array and the second array spontaneously generate a LLEF.
7. The method of claim 6 , wherein the first array and the second array spontaneously generate a LLMC when the arrays are electronically connected.
8. The method of claim 6 , wherein the LLEF is between 0.05 and 5 Volts.
9. The method of claim 8 , wherein the LLEF is between 0.1 and 5 Volts.
10. The method of claim 8 , wherein the LLEF is between 1.0 and 5 Volts.
11. The method of claim 1 , wherein the substrate comprises a pliable material.
12. The method of claim 7 wherein the LLMC is between 1 and 200 micro-amperes.
13. The method of claim 12 , wherein the LLMC is between 1 and 100 micro-amperes.
14. The method of claim 13 , wherein the LLMC is between 100 and 200 micro-amperes.
15. The method of claim 13 , wherein the LLMC is between 150 and 200 micro-amperes.
