Description

technical field

[0001] The present invention relates to a hemostatic dressing and its manufacturing method, and in particular to a hemostatic dressing containing chitosan fiber and its manufacturing method. Background technique

[0002] Chitosan is a polymer obtained by deacetylation of chitin, which is a natural polymer extracted from organisms, mainly found in crustaceans (shrimp, crab, etc.) ), in insect shells, or in the cell walls of fungi. Chitin is a linear polysaccharide polymer formed by β-1,4 bonds of glucosamine and N-acetylglucosamine. Chitosan can be used in biomaterials and medical materials because of its good biocompatibility, bioactivity, non-cytotoxicity and biodegradability with cells. Chitosan has a positive charge in an acidic solution, so it can attract platelets to aggregate, thereby achieving rapid hemostasis.

[0003] At present, dressings composed of chitosan non-woven fabrics have been widely used in clinical practice. However, chitosan dressing...
