Abstract

The invention relates to an anti-bacterial liquid adhesive bandage and a preparation method thereof. The anti-bacterial liquid adhesive bandage comprises, by weight, 10-20 parts of cellulose ether, 5-30 parts of polyacrylate, 150-200 parts of ethanol, 10-30 parts of butyl acetate, 10-20 parts of ethyl acetate, 0.5-1.5 parts of camphor, 5-10 parts of castor oil, 1-5 parts of polydimethylsiloxane and 0.1-0.3 part of anti-bacterial nano particles. After being smeared to a wound, the anti-bacterial liquid adhesive bandage has effects of analgesia, convergence, bacteriostasis, wound healing promotion and the like; the isolation performance is good, bacteria and foreign matter can be prevented from entering the wound, bacteria and fungi on the surface of the wound can be killed, infection is reduced, and the waterproof performance is good. The anti-bacterial liquid adhesive bandage is suitable for wounds different in size, shape and position; after smearing of the anti-bacterial liquid adhesive bandage, a formed film has a certain elasticity, and the coated part can move freely. The anti-bacterial liquid adhesive bandage does not lead to allergy and drug resistance and is high in safety. The anti-bacterial liquid adhesive bandage has no obvious irritation and is convenient to carry and use.

Description

technical field [0001] The invention belongs to the field of medical dressings, and relates to a liquid band-aid, in particular to an antibacterial liquid band-aid and a preparation method thereof. Background technique [0002] Small-area wounds in daily life are mostly treated with alcohol or iodine disinfection first, and then wrapped or protected with gauze or band-aids. Although they can protect the wound surface, there are certain disadvantages. For example, gauze or band-aids are not suitable for special parts. The dressing of the wound surface needs to be replaced repeatedly, which may cause secondary damage to the wound. At the same time, the air permeability is poor after wrapping, and the water vapor and sweat secreted by the wound cannot seep out in time, which will soak the local skin and easily lead to secondary infection of bacteria. , and gauze or band-aid dressing cannot completely isolate the wound from contact with the outside world, and it is easy to cause...
