Liquid bandage and preparation method

Abstract

The invention discloses a liquid bandage and a preparation method. The liquid bandage comprises the following raw materials: polyvinyl acetal, dibutyl phthalate, methyl cellulose, glycerol, laurocapram, chitosan, 95% ethanol, securidaca inappendiculata, dragon blood, frankincense, myrrh and sanchi; the preparation method comprises the following steps: stirring and dissolving the polyvinyl acetal,the chitosan and the ethanol at a temperature of 5 DEG C, and adding the laurocapram, the glycerol, the dibutyl phthalate and the methyl cellulose to obtain film liquid; performing reflux extraction on the crushed securidaca inappendiculata, dragon blood, frankincense, myrrh and sanchi with ethanol at a temperature of 60 DEG C until the extracted liquid is colorless, filtering at a normal pressure and concentrating; and adding the concentrated solution of the securidaca inappendiculata, the dragon blood, the frankincense, the myrrh and the sanchi into the film liquid and mixing uniformly. Theliquid bandage is convenient to use and has high water resistance and air permeability, without sticking on clothes and cotton-padded mattress, causing anaphylaxis and drug resistance or being limited by the shape, size and location of the wound.

Description

technical field [0001] The invention relates to a preparation method of a liquid bandage, which is a medical dressing and belongs to the field of medical technology. Background technique [0002] At present, the products used for wound care in the medical field, such as various band-aids, have the advantages of being cheap, convenient and quick to use, but they also have some defects in use: the adhesive plaster used in traditional band-aids has poor air permeability, and the normal parts of the human body The secreted water vapor and sweat cannot penetrate this layer of adhesive tape, so it has a soaking effect on the local skin, and the specific performance is that the local skin is wrinkled; it is fixed on the wound through the adhesive layer, and the seal between the wound and the outside world is not good, so it is easy to make Dust or water seeps into the wound, making the wound infected and the scar too large; removal effort can easily destroy the new skin; in many wo...

[0002] At present, the products used for wound care in the medical field, such as various band-aids, have the advantages of being cheap and convenient to use, but they also have some defects in use: the adhesive plaster used in traditional band-aids has poor air permeability, and the normal parts of the human body The secreted water vapor and sweat cannot penetrate this layer of adhesive tape, so it has a soaking effect on the local skin, and the specific performance is that the local skin is wrinkled; it is fixed on the wound through the adhesive layer, and the seal between the wound and the outside world is not good. Dust or water seeps into the wound, making the wound infected and the scar too large; removal effort can easily destroy the new skin; in many wounds, the wound is very irregular, and the wound is not easy to use in some specific parts; the chemical drugs in the current wound dressing The ingredients used will cause drug resistance in patients; allergic organisms cannot adapt to the current bandages
