Abstract

The invention relates to a liquid wound surface protective film containing biological glass ceramic and chitosan. The liquid wound surface protective film is prepared by mixing the following components: 1.2g-8.5g of nitrocellulose, 1cc-10cc of biological glass ceramic and chitosan, 1ml-2ml of polyethylene glycol, 0.5ml-1ml of isopropyl palmitate, 0.3g-1.2g of castor oil, 0.6g-1.6g of ethyl acetate, 0.6g-1.4g of butyl acetate, 40ml-80ml of absolute ethyl alcohol, 0.01g-0.5g of benzyl alcohol and 1ml-5ml of glycerol. The liquid wound surface protective film is capable of effectively isolating moisture, dirt and bacteria, preventing wounds from being infected, resisting bacteria and accelerating the healing of a wound.

Description

Technical field [0001] The invention belongs to the technical utilization field of medical materials, and in particular relates to a liquid wound protective film containing biological glass ceramics and chitosan. Background technique [0002] The skin is the largest organ of the human body and one of the most important organs. It has important functions such as resisting the invasion and excretion of external microorganisms, preventing the evaporation of water, regulating body temperature, and maintaining the stability of the body environment. At the same time, the skin is also the most important organ in the human body that is most susceptible to trauma caused by various factors. Small-scale skin injuries such as cuts, scalds, and bumps in daily life have become one of the most important factors that endanger the health of Chinese people, and some injured people have scars because of this. For such problems, we usually use band-aids to solve them. However, due to the problems ...
