EXPIRED GAS MEASURING DEVICE AND METHOD FOR CONTROLLING EXPIRED GAS MEASURING DEVICE

摘要

This exhalation measuring device is provided with a handle component (1), a chamber (23), a piezoelectric pump (44), and a drying mode controller (140). Exhalation is blown into the handle component (1). The chamber (23) temporarily holds the exhalation that has been blown in. The piezoelectric pump (44) supplies the exhalation held in the chamber (23) to a measurement component (45). The dry mode controller (140) executes a drying mode in which the piezoelectric pump (44) is driven and outside air is drawn in from the handle component (1), after the measurement of exhalation by the measurement component (45).
