The pressure limiting valve 163 can control the gas to only flow out of the anesthesia apparatus 100, but not to flow back, and the pressure limiting valve 163 can also control the air pressure of the air path; along with the respiration of the living body, the gas in the gas path will gradually increase, the air pressure will gradually increase, and when the air pressure increases to a set value, the pressure limiting valve 163 automatically deflates to maintain the air pressure in the gas path below the set value; if the pressure limiting valve is not arranged and only the one-way pipeline for exhausting is arranged, in the breathing process of the living body, the living body can normally inhale anesthetic gas when inhaling the gas, but the anesthetic gas can be inhaled when the living body inhales the gasWhen the living body exhales, most of the gas in the gas path enters into CO2Absorbing device, it is partly passed through one-way pipe and is discharged anaesthesia device 100 in all the other expired gases, the expiration of the organism is too abundant this moment, the anaesthetic that leads to exhaling increases, but also can lead to alveolar early closure, the action time of anaesthetic and alveolar shortens, it is slow to make the organism get into the anesthesia state, set up pressure limiting valve 163 back, pressure limiting valve 163 can keep certain malleation at the respiratory track at the end of the organism expiration, make the organism exhale insufficiently, avoid alveolar early closure, make alveolar expansion more even, reach the purpose that improves the blood oxygen, thereby can be better reach the anesthesia effect.
