Many clinical diseases can cause the lack of oxygen supply, which will directly affect the normal metabolism of cells and even seriously threaten human life, so real-time monitoring of blood oxygen concentration is very important in clinical aid.
Traditional blood oxygen saturation is calculated through the electrochemical analysis by blood gas analyzer on the blood collected from human body which is cumbersome without continuous monitoring.
Reusable spo2 sensor can be placed on the appropriate position such as finger which is used to be a transparent container containing hemoglobin and then the compatible patient monitors can collect the intesity of the light from PD&LED on the sensors through the human organization and calculate the pulse oxygen saturation, which can provide a continuous non-invasive pulse oxygen saturation measurement for clinical care.
