PROBLEM TO BE SOLVED: To improve inspection precision by providing a surface acoustic wave(SAW) sensor on an inspection cell storing a biological egesta, and, detecting organic components in the egesta based on changes in the propagation velocity of the SAW wave of the sensor. SOLUTION: In the state seated on a seat 2, the temperature of biological egesta such as urine discharged from a living body is detected with an infrared sensor 21, and a drop position of the egesta is sensed. A urine collection nozzle 18 is moved by a motor 19 to the drop position of urine, for recovering the urine in an egesta recovering part 20 at the tip of the nozzle 18, and transported to an inspection cell 14 with an egesta transportation means 13 such as a pump. For detecting organic component concentration in the egesta housed in the cell 14, the propagation speed of SAW applied from an input interdigital electrode 23 of an SAW sensor 15 is detected with an output interdigital electrode 24. The state of egesta contacting to the surface of a piezoelectric crystal 22 strongly affects SAW propagation, so, changes in SAW propagation speed is detected with a organic component detecting means 16, for detection of organic components in the egesta. |
