Abstract

The invention discloses a closed wound surface treatment dressing system; polyurethane sponge is arranged on non-adhesive gauze; silica gel film is coated on the polyurethane sponge; an instilment tube and a diversion tube are respectively threaded through the silica gel film to be inserted into the polyurethane sponge; the instilment tube and the diversion tube maintained in the polyurethane sponge are respectively provided with side holes; the diversion tube is connected with the inlet tube of a diversion bottle; multi-porous adsorption material is arranged in the diversion bottle; the inlet tube and an outlet tube are respectively inserted into the diversion bottle; gap is maintained between the inlet and the outlet tubes, and the multi-porous adsorption material. The wound surface closed dressing is mainly composed of silica gel film with instilment and diversion tubes, and polyurethane sponge; the materials are all produced domestically and have good quality and low prices; the wound surface closed dressing has simple structure and convenient operation; the negative pressure diversion bottle connected with the wound surface closed dressing has an inverse flow prevention design, so as to facilitate the wild emergency treatment and the popularization in various types of hospitals including the basic level and country medical treatments units, and the VAC technology.

Description

technical field [0001] The invention belongs to medical devices, and in particular relates to a closed dressing system for treating wounds. Background technique [0002] In 1992, Wim Fleischmann, a German medical doctor, pioneered the method of combining wound sealing with traditional negative pressure drainage to promote wound healing. It was quickly promoted in Europe, America and other places. It passed FDA certification and was named VAC technology, which revolutionized wound treatment. Sexual changes. But so far, there are only a few large hospitals in China, and the required instruments and special dressings are all imported, and the price is extremely expensive. The current VAC operation is to debride the wound first, then temporarily insert the drainage tube into a sponge or wrap the drainage tube with gauze dressing, place it on the surface of the wound, seal it with a film, and perform continuous negative pressure suction treatment. The operation is inconvenient ...
