PROBLEM TO BE SOLVED: To enable high precision detection by providing an inspection cell where a biological egesta is housed with a photo-acoustic sensor and detecting a biological component of the egesta from its detection signal. 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 inferred ray sensor 24, and a drop position of the egesta is detected. A urine collection nozzle 21 is driven with a motor 22 to be moved to a urine dropping position, and the urine is recovered by an egesta recovering part 23 at a tip of the nozzle 21, and then it is sent to an inspection cell 14 which is sealed with a sealing chamber 19 by such transportation means 13 as a pump. The light of absorption wavelength of organic components in the egesta is emitted from a light emitting part 15 to the inspection cell 14, and the light is shielded intermittently with an optical chopper 16, and the organic components in egesta are intermittently heated for expansion/contraction of ambient air. The sound wave generated with this is measured with a microphone 17, and with an organic component detecting means 18, the organic components in the egesta is detected. Thus, by raising brightness of the light emitting part 15, measurement precision can be raised. |
