Abstract
Wound dressings and wound inserts comprising substantially dry reactive agents, methods of forming wound inserts comprising dry reactive agents, and wound-treatment methods.
Claims22
A wound insert, comprising:
- an open-celled foam configured to be disposed between a wound of a patient and a drape coupled to skin adjacent the wound;
- and
- a reactive agent disposed within the foam, and configured to be inert in the absence of an activating fluid and to exhibit antimicrobial properties in the presence of an activating fluid;
- where the reactive agent is configured to react with water to release hypochlorite ion and/or form hypochlorous acid.
1 more element
A method comprising:
- adding hypochlorite salt particles to a solution such that the solution and hypochlorite salt form a slurry, the solution comprising a polymer and a liquid that is a solvent of the polymer but not a solvent of the hypochlorite salt;
- substantially removing the liquid from the slurry such that at least a portion of the hypochlorite salt particles are at least partially encapsulated by the polymer.
