Abstract

This invention relates to a multi-layer wound site dressing specifically designed to treat chronic wounds and simultaneously block external pathogens from infecting the wound site from the environment. The said wound dressing comprises five layers; each layer performs a specific functionality in healing and protecting the wound site. The said layers of wound care dressing comprise (i) a permeable non-adherent woven or non-woven membrane in contact with wound site, (ii) a nanofibrous composite layer made of superabsorbent, activated carbon and a polymer (iii) a hydrophobic insulating membrane which is permeable to air with an adhesive edge, (iv) a nanofibrous membrane made of polymer and activated carbon hosting functional germicidal ions, and (v) an air permeable non-woven membrane with adhesive edge. The said layers are compounded by pressing and coating to make a comprehensive multi-layer wound care dressing product.
