Wound care devices having a topically applied silver-based antimicrobial finish are provided. The finish consists essentially of at least one silver ion releasing compound (preferably silver ziconium phosphate, silver zeolites or silver glass) and at least one binder compound (preferably a polyurethane-based binding agent such as witcobon W-293). The finish may be applied to a target substrate, such as a fiber, fabric, or alginate to provide a single layer antimicrobial wound care device, in which the color of the original substrate is substantially maintained after application of the antimicrobial finish. Alternatively, the silver-containing substrate may be combined with one or more additional layers to provide a composite antimicrobial wound care device. The wound care device is preferably constructed so as to provide uni-directional transport of fluid away from a wound site. La présente invention a trait à des dispositifs de soins de plaies présentant un apprêt antimicrobien à base d'argent d'application topique. L'apprêt est essentiellement constitué d'au moins un composé de libération d'ions d'argent et d'au moins un composé à base de liant. L'apprêt peut être appliqué à un substrat cible tel qu'une fibre, un tissu, ou un alginate pour fournir un dispositif de soins de plaies antimicrobien monocouche, dans lequel la couleur du substrat d'origine est sensiblement maintenue après l'application de l'apprêt antimicrobien. En variante, le substrat contenant de l'argent peut être combiné avec une ou des couches supplémentaires pour fournir un dispositif composite de soins de plaies antimicrobien. Le dispositif de soins de plaies est de préférence structuré de manière à assurer un transport de fluide à sens unique en éloignement d'un site de plaie.
