AGSS gasoutlets The basic preparation of ejection anesthetic gas recovery and emission technology: ejection discharge device, pipeline system, positive pressure power source. 1. Ejection discharge device:The anesthetic gas in the operating room is discharged to the outside through thisdevice. The basic principle is to take away the waste gas through the negative pressure area formed by the positivepressure of the operating room and the positive pressure of the compressed air. 2. Piping system: The ejector piping system is the same as the negative pressure piping system. 3. Positive pressure power source:The positive pressure power source is provided by the compressed air in theoperating room. General operating room is equipped with compressed air can be shared, technical pressure controlis not less than 0.5mpa pipe diameter 4mm. 4. filter: the pipeline should be equipped with air narrator,filtration efficiency 99.99%, generally six months toreplace once At the same time, the design of the exhaust port at the end of the pipeline should be aligned with thewind direction to prevent air flow backwards; Wire mesh should be installed in the exhaust port to prevent dustand insects from entering and blocking.
