ABSTRACT:
A nano-silver wound dressing consisting of a skin contact layer made from hydrophilic cloth and directly contacting a wound on the surface of the skin, a disinfecting (or bactericidal) antitoxic layer made from activated charcoal cloth impregnated with nanocrystalline silver, a blood absorbing and styptic layer made from a superabsorbent polymer non-woven cloth, an isolation layer made from a composite fabric with a pore size of less than 5 μm, and an elastic bandage for fixing a main body on the site of wound. Edges of the isolation layer and the skin contact layer are integrated to form a main body while the disinfecting (or bactericidal) antitoxic layer as well as the blood absorbing and styptic layer are separated from each other and both enclosed inside the main body.
