Centralized air supply is one of the necessary items in modern hospital construction projects, and the central suction system is essential in centralized air supply, which together with the centralized oxygen supply system constitutes a medical "life support" system. Its importance is self-evident. The suction system of the medical center was not perfect at the beginning of its establishment. Both the designer and the user took the continuity of the gas supply as the main purpose of the system, and neglected the harmful gas treatment of the system.

The main pipe of the vacuum tank is connected to the pipe well of the hospital building, and the branch pipe is connected to each floor of the building through the pipe well, and then the branch pipe is distributed to each bedside for standby.

Medical suction is mainly used for patients to suck sputum, pus, blood, fluids in the patient's body, and foreign objects. The aspirated objects contain many germs, most of which are infectious germs. Assuming a hospital with 1000 beds, the suction utilization rate is 25% at the same time, that is, there are 250 suction heads at any time to suck out the bacteria-containing gas and bacteria-carrying liquid, enter the vacuum tank through the main pipe, and then pass through the discharge port under the vacuum pipeline vacuum pump circulation drain out. Some hospitals have discharge outlets inside the vacuum station, and some hospitals have discharge outlets nearby outside the station. This is the status quo. The discharge of open germs in a closed system, environmental protection and safety has become an important issue to be solved urgently in the hospital suction system.
