Abstract

The invention relates to a liquid woundplast, and a preparation method thereof. The liquid woundplast is prepared from, by mass, 1 to 5% of matrine, 1 to 5% of oxymatrine, 10 to 15% of circium japonicum, 1 to 2% of borneol, 0.5 to 2% of glycerin, 0.5 to 5% of a transdermal penetration enhancer, 3 to 8% of a film-forming material, and the balance ethanol. The liquid woundplast is capable of promoting wound healing, sterilizing, inhibiting bacteria, and relieving pain, is capable of forming a layer of thin film on the surface of human body, is convenient to use, and is capable of providing safer protection compared with common woundplast; and after coating, the thin film possesses water resistance, and wound surfaces are coated with the thin film firmly.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a liquid bandage and a preparation method thereof. Background technique [0002] Ordinary Band-Aids can cause skin allergic reactions in a small number of people. The application site turns white due to the adhesive tape, and the injured site cannot be wetted with water, and the activities are limited. Liquid band-aid is a kind of liquid medicine film. The prescription contains film-forming materials. When sprayed on the wound surface, a thin film can be formed within 2 minutes. The film body tightly covers the wound surface and is not afraid of water ingress. Protect. Contents of the invention [0003] The purpose of the present invention is to provide a liquid band-aid, which is a new type of hemostatic plaster, which can be directly sprayed on the wound without using ordinary band-aids, gauze and other dressings, and forms a protective layer in 2 minutes. Membrane can quickly ...
