Medical vacuum sealing drainage device

Abstract

The invention provides a medical vacuum sealing drainage device, which comprises a porous foam soft pad and a drainage tube which is arranged in the porous foam soft pad and of which the tail end extends out of the outer side of the porous foam soft pad, wherein an elastic sealing adhesive film extending out of a tube system is arranged on the outer side of the porous foam soft pad; a sealing opening out of which the tube system extends is formed on the elastic sealing adhesive film, and the diameter D of the opening part of the sealing opening is less than the outer diameter of a corresponding extending tube; a plurality of small holes are formed on the side wall of the drainage tube; when multiple drainage tubes are arranged, tail ends of the drainage tubes are connected with a multi-ported joint; a flushing tube is arranged in the drainage tube, one end of the flushing tube extends into the drainage tube, and the other end of the flushing tube is led out from the side wall of the tail end of the drainage tube; a sealing cover is arranged at the tail end of the flushing tube; and the sealing opening out of which the tube system extends on the elastic sealing adhesive film is a circular hole or a tubular hole, and preferably the tubular hole is in an inversed horn shape. The medical vacuum sealing drainage device solves the problems of air leakage of extending parts in the tube system of the vacuum sealing drainage device and sealing serving as the key technology in the vacuum drainage technology completely, and is convenient to operate.

Description

Medical negative pressure sealing drainage device technical field The invention relates to a medical negative pressure sealing drainage device. It is a negative pressure sealing drainage suitable for the treatment of human body surface tissue or body cavity lesions. Background technique 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 negative pressure sealing drainage technology to general surgery for the first time , created a precedent for the application of negative pressure sealing drainage technology in general surgery. The patent CN2236350 authorized by Professor Wang Yanfeng and Qiu Huade in China on March 17, 1997 is the first patent of negative pressure sealing drainage technology. The basic configuration of existing VSD technology incl...

AI Technical Summary

Problems solved by technology

However, there are still many problems in the existing VSD technology: ①The sealing is inconvenient, and the seal between the sealing film and the part through which the drainage tube passes is not tight

③It is difficult to seal when the external fixator is inserted into the needle or the perineal cannula is intubated
