Abstract
An examination apparatus for measuring the oxygenation in body organs by the near infrared light transmission spectrophotometry. The invention relates to an improvement of an illumination-side fixture and a detection-side fixture. In order to hold optical fibers for introducing infrared light in their natural conditions, the fixtures are equipped with respective prisms for changing light paths by prescribed angles. Also, the fixtures are equipped with respective light-emitting diodes for indicating if the examination apparatus is in its operating condition.
