Title:
COMPOSITION OF SURFACE MICROSTRUCTURE OF WOUND DRESSING
Document Type and Number:
WIPO Patent Application WO/2023/130265
Kind Code:
A1
Abstract:
Composition of a surface microstructure (2) of a wound dressing (1). The main body is a dressing (1), comprising a non-woven polymer base material, the surface of which comprises a microstructure (2) formed by stacking at least one metal oxide supporter (21) and two or more nano metal particles (22, 23). The microstructure (2) comprises an inner surface layer which is implanted into the structure of the wound dressing (1) by means of vacuum sputtering and which is thus distributed in the dressing (1). In severe bacterial infection, the dressing (1) can automatically accelerate conversion of hydrogen peroxide into hydroxyl free radicals and superoxide free radicals, so that the sterilization effect is improved. When the amount of bacteria is reduced, the dressing (1) can automatically react to accelerate conversion of hydrogen peroxide into water and small-molecular oxygen, so that proliferation of cells and ends of blood vessels and wound healing are accelerated. The microstructure (2) generates a perfect disc-shaped surface plasma resonance shielding layer (3) to block invasion of external bacteria.
