Description

Technical field[0001]The present invention relates to the technical field of medical equipment, and more particularly to a fiber-based introduction oxygen saturation detecting apparatus and method.Background technique[0002]The traditional blood oxygen saturation measurement method is to prepare a human body, then use a blood analyzer to perform electrochemical analysis, and measure the oxygen partial pressure PO.2Calculate the oxygen saturation. This method is more troublesome and cannot be continuously monitored. There is also a measurement method to use a finger-type photoelectric sensor that uses fingers as a transparent container in which hemoglobin is used, and blood oxygen saturation is calculated by measuring the optical conductivity of the tissue bed. This method can only reflect the change of arterial blood oxygen to some extent, and its measurement accuracy remains to be improved.[0003]The measurement method of venous oxygen saturation is more single, and it is generally n...
