Abstract
Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.
Claims59
A dressing member for treating a tissue site, comprising:
- a plurality of iodine-forming reagents dispersed in the dressing member and adapted to react to produce iodine;
- and
- a covering material encapsulating each of the iodine-forming reagents.

A system for treating a tissue site, comprising:
- a manifold adapted to receive reduced pressure and distribute the reduced pressure to the tissue site;
- a plurality of iodine-forming reagents adapted to react to form iodine;
- a covering material encapsulating each of the iodine-forming reagents;
- a drape adapted to form a sealed space around the tissue site and the manifold;
- and
- a reduced-pressure interface adapted to be in fluid communication with the sealed space and the manifold.

A system for treating a tissue site, comprising:
- a dressing member adapted to be disposed proximate the tissue site and comprising:
- a carrier material, and
- a plurality of iodine-forming reagents adapted to react to produce iodine;
- a drape adapted to cover the dressing member;
- and
- a reduced-pressure interface configured to be in fluid communication with the dressing member and adapted to deliver reduced pressure.
(canceled)
A method for treating a tissue site, comprising:
- applying a dressing member to the tissue site, the dressing member adapted to extend beyond the tissue site and overlapping a peripheral surface surrounding the tissue site, wherein the dressing member comprises:
- a plurality of iodine-forming reagents dispersed in the dressing member and adapted to react to produce iodine,
- a covering material encapsulating each of the iodine-forming reagents;
- and
- delivering iodine formed from the plurality of iodine-forming reagents within the dressing member to the tissue site.
