Abstract

The invention aims at disclosing a chitin gel band-aid and a preparation method thereof. The band-aid comprises a carrier, wherein the carrier is provided with hydrogel hemostasis surgical dressing, the hydrogel hemostasis surgical dressing comprises the following components by weight percentage: 0.5-5% of chitin, 1.5-5% of sodium polyacrylate, 5-10% of sodium carboxymethylcellulose, 0.5-1% of povidone, 0.5-2% of gelatin, 0.05-0.5% of dihydroxyaluminium aminoacetate, 20-40% of glycerinum, 36-71.9% of purified water, and 0.05-0.5% of glacial acetic acid. Compared with the prior art, the chitin gel band-aid has anti-inflammatory and sterilizing functions due to the combination of the wet environment and the effect of the chitin added into the gel, so that the wound can be healed quickly, the pain of a patient is reduced, and the purpose of the chitin gel band-aid is reached.

Description

technical field [0001] The invention relates to a band-aid and a preparation method thereof, in particular to a chitin gel band-aid and a preparation method thereof. Background technique [0002] Chitosan (CTS) is a natural organic polymer polysaccharide derived from shrimp and crab shells. It has good biocompatibility and hemostatic effect, and can prevent the formation of fibrin, the proliferation of connective tissue cells and the The synthesis of collagen has biological properties such as anti-inflammation, antibacterial, promoting wound repair, reducing scar hyperplasia, etc., and can play a hemostatic effect through various ways. It can also protect wounds and absorb wound exudate for large-area burns and scalds. Anti-inflammatory, sterilizing, hemostasis, analgesia, promotion of wound healing and skin regeneration, the above characteristics endow it with good performance as a wound hemostatic material. Chitosan (CTS) has become a hot spot in the research of new hemost...
