摘要
提出了一种通过无线传输实现血氧饱和度测量的无线血氧指夹。其无线功能主要依靠射频芯片nRF905,并利用TI公司的16位单片机MSP430F1232作为控制芯片,用于配置nRF905以完成信号发射、接收的功能,并通过其内部集成的10位ADC采集经放大、滤波后的血容积率信号。这种无线血氧指夹体积小,避免了长导线的麻烦,适用于无线监护系统。结果表明:原理样机经测试通信距离远,数据传输稳定,所传输数据满足计算血氧饱和度要求。
A design for wireless pulse oximetry finger-tip is introduced. The function of wireless is based on nRF905, The 16 bit MCU, MSP430 are used to control the system, The MCU configures nRF905 to transmit and receive data. The signal of pulse oximetry out of the amplifier and filter is sampled by 10 bit ADC on chip, The wireless pulse oximetry finger-tip can be developed to wireless monitoring system. The result shows that the prototype has been tested. The communication distance is long enough and the data transmitted is steady and meets the requirement of calculating of pulse oximetry.
