A kind of liquid bandage and preparation method thereof

Abstract

The invention discloses a liquid wound dressing and a preparation method thereof. The raw materials include polyvinyl alcohol, dioctyl phthalate, glycerin, laurocaprazine, chitosan, and nude flower purple pearl; the preparation method is as follows: After polyvinyl alcohol and ethanol are stirred and dissolved at 50°C, laurocaprazine, glycerin, and dioctyl phthalate are added to prepare a sputum solution; add nudibranchs to the scorpion solution, and mix well. The liquid wound plaster of the invention is easy to use, has the effects of hemostasis, antibacterial, anti-inflammatory, etc., and has the advantages of good water-proof, air-permeable, no allergic reaction and drug resistance, and not limited by the size and shape 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 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 cannot penetrate this layer of adhesive plaster, so it will soak 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; various existing wound plasters have a certain size, which is inconvenient to use fo...

Examples

Embodiment 1

[0033] The liquid bandage provided by the invention is a semi-fluid paste when not in contact with air, and its raw material composition and proportioning ratio are: (parts by weight)

[0034] 80 parts of polyvinyl alcohol 10 parts of dioctyl phthalate

[0035] Laurocaprazine 5 parts Glycerol 10 parts

[0036] 200 parts of 95% ethanol, 70 parts of naked flower purple pearl,

[0037] Its preparation method is:

[0038] (1) Heat 80 parts of polyvinyl alcohol and 200 parts of ethanol in a constant temperature water bath at 50-60 ° C while stirring. After the film-forming substance is completely dissolved, add 5 parts of laurocapram and 10 parts of dioctyl phthalate 10 parts and 10 parts of glycerol, mixed and stirred to obtain a liquid, the stirring speed is 1000rpm;

[0039] (2) Extraction of Auranthus nudica: Take Aurantia nudica, crush it into coarse powder after drying, extract twice with 8 times the amount of purified water, combine the extracts, filter, condense into a t...
