Examination apparatus for measuring oxygenation.

摘要

An examination apparatus (1) for measuring oxygenation can examine a plurality of measurement locations at the same time. The plurality of measurement locations may be a plurality of objects, persons or a plurality of parts of the same object or person. The examination apparatus comprises light source means (LD1m-LD4m, 3-1 to 3-m) for emitting electromagnetic radiation at a number of different wavelengths, a plurality of illumination-side fixtures (6-1 to 6-m), a plurality of detection side fixtures (7-1 to 7-m), transmitted light detection means (4), and a computer system (2) for controlling the apparatus and analysing the results. The light source means typically emit near infrared light radiation of four different wavelengths. Transmitted radiation from the plurality of measurement locations are sequentially measured with a time-sharing method.
