Negative pressure drainage closed conduction device for extremity burn wounds

Abstract

The invention provides a negative pressure drainage sealing conduction device for burn wounds of extremities, comprising a porous foam negative pressure conduction layer, a sealing film, and a backing film from the inside to the outside, and the two ends and one side of the sealing film and the backing film have Extended hemming for wrapping, that is, sealing film end hemming and backing film end hemming and sealing film side hemming and backing film side hemming, with end separation on the inner side of sealing film end hemming and sealing film side hemming liner and side release paper. There are dimension marks on the end liner and side liner. In the present invention, the porous foam negative pressure conduction layer is composed of a medical film, a sealing film, and a backing film to form an integrated structure. paste. The occlusive dressing is tailorable to fit arms of different ages and sizes. Dimensions are used to guide the physician's cropping.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a negative pressure drainage sealing conduction device for limb burn wounds. Background technique [0002] Vacuum sealing drainage technology (vacuum sealing drainage, referred to as VSD) was pioneered by Dr. Wim Fleischman of ULM University in Germany in 1992, and formed a theoretical prototype for the drainage of extremity wounds; in 1994, Professor Qiu Huade of China applied the vacuum sealing drainage technology for the first time In general surgery, pioneered the application of negative pressure sealing drainage technology in general surgery. Professor Wang Yanfeng and Qiu Huade obtained the patent CN 2276350 authorized in China on March 18, 1998, which is the first patent of negative pressure sealing drainage technology. Since then, negative pressure sealing drainage technology has been greatly developed in our country. [0003] The negative pressure sealing drainage techn...
