Abstract

The invention discloses an anthocyanin alginate dressing. The anthocyanin alginate dressing is obtained by adopting a transparent medical adhesive to glue a thin film layer and a fiber web layer; the thin film layer is prepared from, by weight, 70-80 parts of alginate, 25-35 parts of anthocyanin, 10-20 parts of cyclodextrin, 10-15 parts of hyaluronic acid, 10-15 parts of collagen, 5-10 parts of caffeic acid, 3-5 parts of flos carthami powder, 1-3 parts of notoginseng radix et rhizoma powder, 2-3 parts of vegetable oil, 2-3 parts of cow's milk, 0.1-0.5 part of an emulsifying agent, 0.5-1 part of growth factors and 0.5-1 part of vitamin K by adopting a 3D printing technology; the fiber web layer is prepared from, by weight, 30-40 parts of aloe fibers, 10-15 parts of bamboo fibers, 15-18 parts of polyethyleneimine carrying silver ions, 8-9 parts of silk fibers, 5-6 parts of carboxymethyl chitosan, 2-3 parts of microcrystalline cellulose and 2-4 parts of polyethylene glycol through spinning. The anthocyanin alginate dressing has excellent effects of inhibiting bacteria and shortening wound healing cycles.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to an anthocyanin alginate dressing. Background technique [0002] The skin provides protection for the human body. Once the skin is injured, it will have a great impact on body functions; therefore, after the skin is injured, it is necessary to use dressings to protect the wound to avoid infection of the wound; alginate is a biopolymer material , has non-toxic, biodegradable and good biocompatibility, so it is widely used in medical dressings, its good moisture absorption ensures the efficient adsorption of wound exudate, and also has a certain hemostatic effect, but algae Because of its weak mechanical strength, alginate dressing is easy to stick to the wound, and it will cause secondary damage to the wound in serious cases; and simple alginate does not have the effect of bactericidal and antibacterial, so it is usually necessary to add bactericide to the dressing, while The exist...
