Abstract

The invention discloses a gel adhesive bandage, and belongs to the field of medical instruments and apparatuses. The adhesive bandage is characterized by being prepared from, by weight, 1-1.5 parts ofchitosan, 1-3 parts of vitamin C, 10-28 parts of chitosan oligosaccharide and 20 parts of purified water; the adhesive bandage has the advantages that the adhesive bandage is simple and convenient touse, cannot be limited by the wound position and size, can be easily stored, has antibacterial and analgesic effects, can inhibit protruding scars caused by dysplasia of wound tissue, and can removepurple pigment chromatosis caused by infection of the wound tissue.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a wound dressing and a preparation method thereof. Background technique [0002] Chitosan, also known as deacetylated chitin, is obtained through deacetylation of chitin that exists widely in nature, and its chemical name is polyglucosamine (1-4)-2-amino-B-D glucose. This natural polymer has excellent properties such as biofunctionality, compatibility, blood compatibility, safety, and microbial degradation. Chitosan can be cross-linked and film-formed after being dissolved in an acidic solution, but it dissolves slowly in an acidic aqueous solution, requires stirring for defoaming, and is easily degraded, which limits its application. Chitosan oligosaccharide, also known as chitosan oligosaccharide and oligochitosan, is a kind of polysaccharide obtained by degrading chitosan by special biological enzyme technology (there are also reports of chemical degradation and mic...
