Then, it falls along the groove 16 due to its own weight, and the water fall port 1
3. It accumulates in the water receiving part 7 through the drain part 14 and the hole 18. Further, the air in the water receiving portion 7 is sucked through the suction pipe 19 and has an internal pressure lower than the atmospheric pressure, so that the dew drops in the gas-liquid separation chamber 11 easily fall into the water receiving portion 7. However, the respiratory gas from which water is separated in the gas-liquid separation chamber 11 is
It is sucked through the gas exhaust passage 17 with a stronger force than the expiratory tube 19 and is guided to the sensor unit of the respiratory gas analyzer.
