<P>PROBLEM TO BE SOLVED: To accurately measure a small amount of specific gas constituent contained in expiration. <P>SOLUTION: An expiration measuring device 100 comprises a desorption line 108 through which a patient blows expiration, an introduction line 106 for introducing the expiration into the measuring device connected to the desorption line 108, a permselective membrane 118 for passing the specific constituent of the introduced expiration, a sensor 122 for expiration measurement, and a sensor 120 exposed to the outside air. A measured value of the specific gas constituent in the expiration blown out of the inside of the body is output based on a value obtained by correcting the output of the sensor 122 using the output of the sensor 120. <P>COPYRIGHT: (C)2010,JPO&INPIT |
