Background technique [0002] The intensity of the UHV transmission line staff is very high, especially in many high court areas. Due to the lack of oxygen supply, it directly affects the normal metabolism of cells, and seriously threatens human life. Therefore, the real-time monitoring of blood oxygen saturation is in the It is very important in clinical rescue. The blood oxygen saturation measurement method in the prior art is to first collect blood from the human body, and then use a blood gas analyzer to perform electrochemical analysis, measure blood oxygen partial pressure and calculate blood oxygen saturation. This method is cumbersome and cannot be monitored continuously. [0003] There are still some finger cot photoelectric sensors in the prior art.
