Embodiment 1

[0012] The liquid band-aid of the present invention is composed of 2% polyvinyl alcohol, 2% gum rosin, 2% beeswax, 15% gum turpentine, 75% ethanol and 4% purified water in terms of mass percentage.

[0013] A kind of technique for preparing described liquid band-aid, concrete steps are:

[0014] 1) Premixing: Add 8g gum rosin, 8g beeswax, and 8g gum turpentine into 300g ethanol, and mix well;

[0015] 2) Heat 16g of purified water to 90°C, keep it warm for 25 minutes, then cool down to 40°C;

[0016] 3) Add 8g of polyvinyl alcohol into the cooled purified water, fully stir and disperse evenly;

[0017] 4) Add the premixed material into the mixed liquid treated in step 3), stir and dissolve, and obtain the liquid band-aid.

[0018] The liquid band-aid of the present invention is a spray preparation, which is sprayed directly on the wound surface during use, and quickly forms a layer of transparent film on the wound surface. The film also has a waterproof effect and can be kep...

Abstract

The invention discloses a liquid woundplast and a preparation technology thereof. The liquid woundplast comprises the raw materials based on weight percentage: 1%-5% of poval, 1%-5% of gum rosin, 1%-5% of beewax, 10-30% of gum turpentine, 60-90% of 75% alcohol and 1%-8% of purified water. The preparation technology of the liquid woundplast comprises the steps of: adding the poval into the heated and cooled purified water, abundantly stirring and evenly dispersing, adding the mixture of the gum rosin, the beewax, the gum turpentine and the alcohol, and dissolving in a stirring way to obtain the liquid woundplast. The liquid woundplast is taken as a spray agent to be directly sprayed to the wound when the liquid woundplast is in use, a layer of transparent film can be fast formed on the wound, and the transparent film has a waterproof function, can not fallen off for 72h, and can prevent the wound from being invaded by the external bacterium, so that the wound can be fast healed, and the problems that the conventional woundplast is unattractive in appearance and the wound is unfree to move are solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a liquid band-aid and a preparation process thereof. Background technique [0002] The common band-aids on the market today, one is medical adhesive tape + non-woven fabric, and the other is PU film + non-woven fabric, which are pasted on small wounds, which will affect the free movement of the wound site, and also greatly affect the appearance. Contents of the invention [0003] The object of the present invention is to provide a liquid band-aid of spray preparation type and its preparation process, which solves the defects of traditional band-aids that affect the appearance and prevent the movement of the wound. [0004] Liquid band-aid, calculated by mass percentage, consists of 1% to 5% polyvinyl alcohol, 1% to 5% gum rosin, 1% to 5% beeswax, 10% to 30% gum turpentine, 60% to 90% 75% ethanol and 1% to 8% purified water. [0005] A kind of technique for preparing described l...
