中文摘要:
针对现代战场装甲救护车内缺乏便携式医疗设备的情况,本文设计一种适用于装甲救护车的腕式体征参数监测装置.装置采用基于反射式原理的MAX30102生物传感器获取光电容积脉搏波(photo plethysmo graphy,PPG),利用低通滤波器、最小二乘多项式拟合去除PPG信号的高频噪声和基线漂移,通过STM32单片机完成信号处理以及计算血氧饱和度、脉率参数,体征参数不仅实时显示在OLED屏幕上,也写入近场通信(near field communication,NFC)标签,通过近场通信阅读器传输至终端供医疗人员参考.经测试装置血氧误差为±3%,脉率误差为±5次/min,近场通信成功率97%.
English Summary:
In view of the lack of portable medical equipment in modern battlefield armored ambulances, a wrist-type physical parameter monitoring device was designed for armored ambulances. In the device, a reflective principle based MAX30102 biosensor was used to acquire the photoplethysmogra-phy (PPG). The low-pass filter and least squares polynomial were used to remove the high-frequency noise and baseline drift in the PPG signal. The signal processing was completed and the blood oxygen saturation, pulse rate signs parameters were calculated by the STM32 microcontroller. Physical parameters was arranged to not only display in real time on the OLED screen, but also to be written near field communication (NFC) tags, and transmitted to the terminal through the near field communication reader for medical personnel reference. According to the test result, the blood oxygenation error of device can attain ±3%, the pulse rate error attain ±5 times/minute, and the near field communication success rate attain 97%.
