Sensor for optical measurement blood oxygen saturation, the measuring method, and its measurement equipment

摘要

(57) Abstract Concerning the new optical blood oxygen saturation measurement sensor, with measuring method and the device which use the new sensor it states. As for the new sensor, on the median of the device mutually one which is provided concentrically around two point condition luminous vessels and the luminous vessel which is the position where the vicinity it does, it includes with two annular detection terminals at least desirably. As for the illuminant, for example, it is possible to make two laser diodes which give out the monochromatic radiation inside the range 670 - 940nm respectively. The detection device for example is the photodiode.
