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. The invention also provides a method for making the wound care device and a composition of matter comprising the silver-based antimicrobial finish.

Description

[0001] This application is a divisional application of a patent application with an application date of July 15, 2004, an application number of 200480023257.3 (PCT / US2004 / 022825), and an invention title of "silver-containing wound care device, its composition and manufacturing method". technical field [0002] The present invention relates to wound care devices topically coated with silver-based antimicrobial finishes. The finish can be coated on a target substrate to provide a single layer antimicrobial wound care device. Alternatively, the silver-containing layer can be combined with one or more other layers of the target substrate to provide a composite antimicrobial wound care device. The device may also contain an odor absorbing composition capable of reducing or eliminating odors inherently associated with infected wounds. In a potentially preferred embodiment, a silver-based antimicrobial finish is topically coated on a nonwoven fabric composed of multicomponent fibers...
