Abstract
Abstract A concave urine collector (4) is set under a front end portion of a stool body (1), so that urine can be collected in a bowl (3). Single fiber holes (13L, 13R) are set on a front end and a left side of the urine collector (4) respectively, while condenser lenses (15L, 15R) for condensing light on the bowl (3) side, an excitation light fiber member (5) carrying excitation light from an excitation light source (14) and a Raman light receiving fiber member (6) for receiving Raman light are set in the fiber holes (13L, 13R) respectively. The excitation light fiber member (5) is connected with the excitation light source (14), and the Raman light receiving fiber member (6) communicates with a spectro-detector (10). A Raman signal separated into its spectral components detected by the spectro-detector (10) is data-processed by a data processing part (11), and outputted from a data output part (12) as a measurement result.
