Topical silver-based antimicrobial composition for wound care devices
First Claim
1. A composition of matter for chemically treating a substrate without causing discoloration of said substrate to achieve a wound care device exhibiting controlled release of silver ions of less than about 50 μ
- g/cm2 over a 24 hour period comprising;
at least one compound delivering silver ions and at least one binder material, wherein said at least one binder material is selected from the group consisting of polyurethane, acrylic, and any mixtures thereof.

Abstract
Wound care devices having a topically applied silver-based antimicrobial finish are provided. The finish comprises at least one silver ion-containing compound and at least one binder compound. The finish may be applied to a target substrate, such as a fiber, fabric, film, foam, hydrogel, or hydrocolloid to provide a single layer antimicrobial wound care device. Alternatively, a silver-containing layer may be combined with one or more additional layers of target substrate to provide a composite antimicrobial wound care device. The device may also contain an odor-absorbing component capable of reducing or eliminating odors that are inherently associated with infectious wounds. Also provided is a method for making the wound care device and a composition of matter comprising the silver-based antimicrobial finish.
