Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] figure 1 It is a schematic diagram of the patient side of anesthesia machine ventilation. When the anesthesia machine is ventilating, during the inhalation phase, the gas flows from the patient circuit to the patient. Because of the effect of CV2, the air flow will not go through the B2 path, but can only flow into the patient from the B1 path, so the air flow direction during inhalation is: Patient circuit → CV1 → SE1 → B1 → patient, SE1 can measure the flow at this time, and the inhalation capacity can be obtained by integrating the flow, SE2 has no flow, so the flow measured by SE2 is 0 in theory; During the phase, the gas flows from the patient to the patient circuit. Because of the function of CV1, the air flow will not go through the B1 path, but can only flow into the patient from the B2 path. Therefore, the air flow direction during exhalation is: patie...
