The invention relates to a wound-protecting liquid, which is suitable for controlling the infection of wounds on the human body surface and promoting wound healing, and also relates to a preparation method of the wound-protecting liquid, which belongs to the technical field of medicine for medical surgery. Each 1000g weight of the finished solution formed by it contains: silver ion powder 0.16-0.36g, gelatin 0.10-0.40g, dibasic acid 0.50-1.00g, penetrant 12-14.3g, tartaric acid 0.40-0.80g, The rest is pure water. One of the advantages is that the stabilizer with penetration effect is used in the formula, which can penetrate into the deep tissue of the wound, kill the bacteria and endotoxin in the deep part, and loosen and dissolve the necrotic tissue, pus and blood clots out of the body, which helps It can shorten the wound healing time; second, it will not form obvious drug film and drug resistance after long-term use, and can effectively shorten the treatment cycle; third, it has no side effects on patients and the product has no peculiar smell and no allergies; fourth , the method has few process steps, and the conditions are not harsh, and can adapt to the requirements of mass production.

The invention provides a medical vacuum sealing drainage device, which comprises a porous foam soft pad and a drainage tube which is arranged in the porous foam soft pad and of which the tail end extends out of the outer side of the porous foam soft pad, wherein an elastic sealing adhesive film extending out of a tube system is arranged on the outer side of the porous foam soft pad; a sealing opening out of which the tube system extends is formed on the elastic sealing adhesive film, and the diameter D of the opening part of the sealing opening is less than the outer diameter of a corresponding extending tube; a plurality of small holes are formed on the side wall of the drainage tube; when multiple drainage tubes are arranged, tail ends of the drainage tubes are connected with a multi-ported joint; a flushing tube is arranged in the drainage tube, one end of the flushing tube extends into the drainage tube, and the other end of the flushing tube is led out from the side wall of the tail end of the drainage tube; a sealing cover is arranged at the tail end of the flushing tube; and the sealing opening out of which the tube system extends on the elastic sealing adhesive film is a circular hole or a tubular hole, and preferably the tubular hole is in an inversed horn shape. The medical vacuum sealing drainage device solves the problems of air leakage of extending parts in the tube system of the vacuum sealing drainage device and sealing serving as the key technology in the vacuum drainage technology completely, and is convenient to operate.
