EXHALATION MEASURING DEVICE AND METHOD FOR CONTROLLING EXHALATION MEASURING DEVICE

摘要

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

主权项

1. An exhalation measuring device, comprising:
a handle component into which exhalation is blown; a chamber into which the exhalation is supplied from the handle component through a tube and temporarily held; a pump for supplying the exhalation held in the chamber to a measurement component; a controller for controlling an operation of the pump; and a temperature sensor that is connected to the controller, wherein the controller: determines whether or not to perform a drying mode for removing condensation inside the tube, on the basis of temperature acquired by the temperature sensor, after the measurement of exhalation by the measurement component, and drives the pump to draw in outside air from the handle component and supply it to the tube when it has been determined to perform the drying mode.
