Abstract

The invention provides a traditional Chinese medicine compound polysaccharide-silver nano liquid band-aid and a preparation method thereof, and relates to the technical field of medical supplies. The traditional Chinese medicine compound polysaccharide-silver nano liquid band-aid is prepared from the following raw materials in parts by weight: 40 to 60 parts of aizoon stonecrop herb, 30 to 50 parts of echinacea, 30 to 40 parts of absolute ethyl alcohol, 20 to 40 parts of distilled water, 15 to 25 parts of AgNO3 solution, 20 to 30 parts of PVA, 40 to 60 parts of chitosan, 40 to 60 parts of chitosan quaternary ammonium salt and 10 to 15 parts of ethyl acetate. Through reasonable compounding of the natural traditional Chinese medicine extract and the green synthetic silver nanoparticles, the mixed medicine has the advantages of safety, no toxicity, sterilization, detumescence and the like, and the adhesive bandage prepared from the mixed medicine has the advantages of uniform film formation, wound sealing, reduction of entry of external pathogenic microorganisms, reduction of accumulation of wound tissue fluid, difficulty in falling and the like, and is suitable for large-scale popularization and application. The defects of products of the same type on the market can be overcome, and the wound healing agent is better suitable for healing wounds of human bodies or animal bodies.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a traditional Chinese medicine composite polysaccharide-silver nano liquid band-aid and a preparation method thereof. Background technique [0002] Liquid Band-Aid is a smear dressing composed of liquid polymer materials, which is applied to superficial wounds on the body surface. With the characteristics of breathability, bacteria resistance, wound protection, wound healing promotion, and scar reduction, the liquid band-aid can quickly form a protective film with certain toughness on the wound surface, reduce water volatilization, enhance the hydration of wound tissue, and create a moist healing environment . [0003] The liquid band-aids that have been developed on the market have poor film-forming properties, promote healing and have poor anti-infection effects. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the invention provides ...
