Problems solved by technology

[0002] At present, the products used for wound care in the medical field, such as various band-aids, have the advantages of low price and convenient use, but there are also some defects in use: the adhesive plaster used in traditional band-aids has poor air permeability, and the normal secretion of human body parts The water vapor and sweat of the adhesive layer cannot penetrate this layer of adhesive tape, so it will soak the local skin, which is specifically manifested as local skin wrinkling; it is fixed on the wound through the adhesive layer, and the wound is not well sealed with the outside world, so it is easy for dust or Water seeps into the wound, making the wound infected and the scar too large; various existing wound plasters have a certain size, which is inconvenient to use for some specific wound parts. Drug resistance often occurs

At present, there are also studies on liquid bandages, such as ZL200410031161.3, but there are few products with definite curative effect
