Operation principle, function and structure

The patient sensor end of the product is clamped the patient's index fifinger with (Thumb, middle
fifinger or others, great toes), and the device connector is connected to compatible monitors or
oximeters with SpO2 extension cord. The product adopts 660nm red light and 905nm Infrared light as
incident light source, tests light intensity through tissue to obtain SpO2 value as well as pulse rate.
