ABSTRACT
Objective:
To develop a reflection-type blood oxygen monitor module can transmit message by a new wireless sensor and be used as a terminal monitoring node in wearable devices.Methods:
The blood oxygen algorithm is mathematically analyzed by Lambert Beer law; the terminal schematic diagram of hardware, drive circuit, transimpedance amplifier and filter circuit of sensor NJL5501R are analyzed and designed to use in the module; the software process and algorithm implementation is described by special software; the Fluke INDEX2XLF is used to simulate blood oxygen saturation and determine the Q value and then to establish relevant relationship between blood oxygen saturation and Q value.Results:
The module can collect blood oxygen data and transmit them by wireless method. And detection result error was less than 2% when this module was compared with the MINDRAY IPM10.Conclusion:
The module achieves the expected effect although it still need be improved in some aspects, such as anti movement interference, miniaturization design and low power consumption.
