Document Type and Number:
Japanese Patent JP5886060
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a respiratory flow rate measuring device capable of accurately and easily executing calibration of a respiratory flow rate.SOLUTION: A CPU which receives a count value of pulses from an air-flow-for-calibration supplier calculates reference flow corresponding to the received count value on the basis of the relational expression of the count value and flow (S13), measures the flow of air flow for calibration supplied to a flow sensor (S14), and calculates a calibration coefficient by the reference flow/measured flow (S15). Then, a value is obtained as a respiratory flow rate after calibration by multiplying a respiratory flow rate before calibration, which is measured by the flow sensor, by the calculated calibration coefficient.
