Abstract

The invention belongs to the technical field of medical treatment and relates to a waterproof ventilating liquid adhesive bandage and a preparation method thereof. The waterproof ventilating liquid adhesive bandage comprises, by weight, 5-20 parts of nitrocellulose, 30-70 parts of acetone, 0.1-1 part of polyvinylpyrrolidone, 10-50 parts of ethanol, 4-15 parts of tributyl 2-acetylcitrate and 3-10 parts of ether. A wound part can be directly coated with the waterproof ventilating liquid adhesive bandage and after coating, a film is fast formed, tightly covers the wound surface, has waterproof and ventilating effects and is convenient for use. The waterproof ventilating liquid adhesive bandage can effectively promote wound heal, prevent infection and reduce pain.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a waterproof and breathable liquid band-aid and a preparation method thereof. Background technique [0002] At present, ordinary band-aids on the market need to use medical adhesive tape to stick to the wounded part of the human body. The adhesive tape will cause the skin of the bandaged part to turn white, and some people may even have skin allergic reactions. Liquid Band-Aid is a new type of Band-Aid. Because the formula contains film-forming materials, it can be directly applied to the wound surface, and a protective film can be formed in a short time, waterproof, pollution-proof, rapid hemostasis, sterilization, pain relief, swelling, and relief. Edema scar formation, promote wound healing, without the use of adhesive tape. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a waterproof and breathable liquid ba...
