ABSTRACT:
An examination apparatus measures the oxygenation in body organs by the near infrared light transmission spectrophotometry. To inspect the examination apparatus itself before the oxygenation measurement, an illumination-side fixture and a detection-side fixture have such structures that these fixtures can be assembled together in such a manner that near infrared light is directly made incident on the detection-side fixture from the illumination-side fixture. In the midst of the measurement, the examination apparatus is regularly inspected and a photomultiplier tube can be separately inspected by employing a separate light source for inspection.
