Problems solved by technology

Existing wound liquid protective film agents mostly use spraying to act on the skin. Due to the need for film formation, it is often difficult or easy to spray out due to excessive viscosity, or the fluidity of the liquid is good, but the film-forming Insufficient strength, easy to be damaged, unable to effectively isolate bacteria

Abstract

The invention relates to wound protective film spray and a preparation method thereof. The wound protective film spray is prepared from the following components in parts by mass: 0.005 to 0.05 part of glycyl-glycine endopeptidase, 0.1 to 0.3 part of chloroxylenol, 4 to 7 parts of polyvinylpyrrolidone-K90, 2 to 10 parts of polyvinyl alcohol, 0.2 to 0.8 part of sodium carboxymethylcellulose, 20 to 30 parts of ethyl alcohol and 49 to 65 parts of pure water. The wound protective film spray disclosed by the invention has the characteistcis of short film forming time, high film strength and long antibacterial time.

Description

technical field [0001] The invention relates to the field of medicinal disinfection products, in particular to a wound protective film spray and a preparation method thereof. Background technique [0002] Small-scale skin trauma such as knife wounds, scalds and bumps in daily life has become one of the important factors that endanger the health of Chinese people. According to the survey, among the 12,000 respondents, 78.7% said they had suffered such skin trauma, and 45.9% of them left scars. The survey also shows that because Chinese people have the psychological habit of "severe illness and minor injury", they don't pay much attention to the usual small skin injuries, which are very likely to lead to serious consequences. Medical experts said that the skin is the largest organ of the human body and one of the most important organs. After the skin is injured, the wound becomes red, swollen, hot and painful, and it is difficult to heal for a long time. The reasons are very ...
