Our products are one-time use of vacuum-assisted wound care materials (referred to as suction drainage VSD). The protective material is composed of polyvinyl alcohol foam creation and insertion of the foam material in the drainage catheter or multiple side holes dedicated drainage catheters. Wherein the material is a medical drainage polyvinylalcohol (PVA) as raw materials, the acetalization reaction, the foam prepared by expansion molding of synthetic material. The material is non-fibrous three-dimensional porous structure and elastic, anti Zhang Liqiang, biocompatibility, chemical stability, good hydrophilic, aspiration, through performance. The drainage material as an intermediary suction drainage tube and the drainage of the wound between the paste and then apply biological breathable film the entire drainage area, which form a relatively closed environment, then turn on a variety of medical vacuum source, you can compose efficient drainage system. The material for a variety of wounds, ulcers or prophylactic treatment of disposable drainage. [Manufacturer name] Foshan UTS Kang Biotechnology Co., Ltd.
