Title:
EXPIRED AIR MEASURING DEVICE AND MICROPHONE-APPLIED DEVICE HAVING FUNCTION OF THE SAME
Document Type and Number:
Japanese Patent JP2002039981
Kind Code:
A
Abstract:
To provide an expired air measuring device with improved reproducibility and accuracy, in alcohol measurements and oral odor measurements.
The expired air measuring device is provided with both a gas sensor 6 for detecting the components of expired air and a control part 10, to determine the state of blowing of the expired air to the gas sensor 6 on the basis of a signal of an audio sensor 5. The state of blowing, when the expired air is blown to the gas sensor, is determined by an audio signal by a microphone.
