<p>A movable member 13, whose physical change occurs corresponding to respiration flow rate, is disposed in the pipe 11. The pipe 11 and a holder section are structured to be capable of being detachable. When staring respiration with the mouth touching to the pipe 11, the movable member 13 bends corresponding to respiration flow rate. Image data of the movable member 13 is obtained through the pipe 11 by a CCD area sensor disposed outside the pipe 11 and the bending amount is detected. The respiration rate is calculated based on the flow rate data corresponding to the bending amount of the movable member 13 in use.</p> |
