[0027] The present invention will be further described now in conjunction with accompanying drawing.
[0028] figure 1 The position and function of the IP valve in the anesthesia machine system are shown. When the anesthesia machine is working, when the gas from the gas source enters the bellows folding bag through the pressure reducing valve, proportional valve, safety valve and other components, a certain airway pressure will be generated, and the IP valve will play a certain role in the airway pressure. restrictions and adjustments. The purpose of calibrating the IP valve is to ensure that it can adjust the pressure accurately and effectively, that is, how much pressure the IP valve wants to control, and how much voltage will be passed to it. The control pressure and corresponding voltage value of the IP valve are determined when the IP valve is calibrated. The control pressure and voltage value can form a data relationship curve between the control pressure and voltage o...
