Background
Traditionally, dressings for the treatment of wounds have been made of cotton gauze. In the last 60 s of the century, the importance of maintaining wound moisturization was discovered and a wide variety of hydrogels, alginates and other polymer-based and biologically functional dressings were developed. Through the deep research and clinical application practices, the wound dressing and the biological semi-permeable membrane are combined together to form a closed space locally, and are connected with a negative pressure device through a drainage tube or a sucker, and a negative pressure drainage therapy (NPWT) is produced at the discretion. From creation to now, the method has been continuously developed and perfected, is widely used for treating various acute and chronic wounds and achieves better curative effect. In the 70 s of the 20 th century, the soviet union has reported documents for applying negative pressure to treat wounds. In 1985, the american physicians Chariker and Jeter wrapped the drainage tube with gauze and placed into the wound, covered with a transparent sealing patch and connected the drainage tube to a negative pressure pump to treat patients with intestinal fistula, achieving a certain therapeutic effect. In 1993, German surgeons Fleischmann and the like firstly apply negative pressure to treat soft tissue wound infection, and obtain positive effects. In 1994, fur china introduced negative pressure therapy technology for general surgery and treatment of infectious wound, and named negative pressure closed drainage (VSD). At present, NPWT obtains good effect in clinical use, and research shows that negative pressure drainage treatment can effectively control infection of various acute and chronic wound surfaces, promote granulation tissue growth, timely remove wound surface secretion, reduce wound surface area and promote wound surface healing.
