Abstract：
 The blood oxygen parameter measuring method capable of correcting the influence of outer tissue belongs to the field of biomedicine engineering. The present invention features that for different measured targets and different biological tissues, proper detection distance is selected in detecting oxidized hemoglubin variation and reduced hemoglubin variation; sensor design, detection steps, algorithm and system design are proposed in considering the influence of outer tissue. The sensor consists of three LED's and one photoelectric detector; and the whole test system consists of sensor, pre-amplifier, A/D converter, embedded micro controller, communication circuit, power supply, LCD and touch screen. The present invention has the advantages of high detectioin sensitivity and simple detection system structure.
