The invention provides a negative pressure drainage closed conduction device for four-limb burn wounds. The negative pressure drainage closed conduction device comprises a porous foam negative pressure conduction layer, a sealing membrane and a backlining membrane from inside to outside, wherein two ends and one side of the sealing membrane and the backlining membrane are provided with extended coating edges, namely sealing membrane end coating edges, backlining membrane end coating edges, a sealing membrane side coating edge and a backlining side coating edge, the outer sides of the sealing membrane end coating edges and the sealing membrane side coating edge are provided with end release paper and side release paper, and the end release paper and the side release paper are provided with size marks. According to the negative pressure drainage closed conduction device disclosed by the invention, the porous foam negative pressure conduction layer, a medical adhering membrane, the sealing membrane and the backlining membrane are formed into an integrated structure; an adhering membrane conduction layer is slightly large and is used for carrying out sealing adhesion on a connecting seam part after limbs are covered by sealing surgical dressing; the sealing surgical dressing is suitable for arms in different ages and different sizes as the sealing surgical dressing is cuttable; the size marks are used for guiding the cutting of a doctor.
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, he pioneered the application of negative pressure sealing drainage technology in general surgery. Professor Wang Yanfeng and Qiu Huade obtained the patent CN2276350 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 tec...
