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, hydrogen, 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.

Description

technical field [0001] 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 at least partially split into their microdenier components. Such a structure provides a greater surface area on which silver ions can adhere, thereby increasing the amount of surface-available silver present on the wound care device used to promote wound healing. This construction furt...
