A test system for the conductivity of medical negative pressure sealing drainage materials

Abstract

The invention provides a medical vacuum sealing drainage material conductivity testing system. The system comprises a host, a tested material arranging and supporting device and a pressure source part, the host comprises a microcontroller, and a display panel and a button connected with the microcontroller, the input end of the microcontroller is connected with 1-n pressure sensors, the input port(s) of the 1-n pressure sensors is / are connected with 1-n conduction measuring pipeline(s), and the output end of the microcontroller is connected with the air pump control switch of the pressure source part; the pressure source part comprises an air pump, a seepage drainage bottle connected with the air pump, and an interface connected with a drainage pipeline on the seepage drainage bottle; and the material arranging and supporting device comprises a tested vacuum material arranging groove, and 1-n pressure test holes is / are uniformly distributed on the bottom of the arranging groove. The system solves a problem that the vacuum sealing drainage material conductivity cannot be tested for a long time, and ends the history that the vacuum sealing drainage material conductivity cannot be quantitatively foreseen. The system can continuously and stably provide a preset rated negative pressure value, and can monitor and display the negative pressure values of all measured points in real time.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a testing system for the conductivity of medical negative pressure sealing drainage materials. 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 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 CN2276350 authorized by Professor Wang Yanfeng and Qiu Huade in China on March 18, 1998 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 pre...

Problems solved by technology

[0008] Due to the short time that the negative pressure sealing drainage technology has been available, there is currently no special equipment on the market to measure the conductivity of the porous foam cushion material. The porous foam cushion material products of the negative pressure sealing drainage in the domestic and international markets are mixed, and there is generally a shortage. Technical control of the conductivity of porous foam upholstery materials, seriously affecting the level of patient care
