摘　　要：脑电遥测监护系统由脑电采集发射器和脑电接收器组成。该系统在脑电采集发射器中选用了精密放大器OP777和仪表放大器AD8222实现了脑电信号的放大和滤波;采用微控制器C8051F320集成的USB2.0接口实现了脑电接收器与计算机之间的脑电数据传输。此外整套系统通过采用高集成度的无线收发芯片ADF7020使患者与网电源完全隔离,达到了医疗器械安全级别的要求。A telemetry EEG monitoring system is designed. The system is composed of two parts. They are telemetry EEG transmitter and telemetry EEG receiver, respectively. The amplification and filtering of EEG signals are realized by using the precision amplifier OP777 and an instrument amplifier AD8222. Moreover, the transmission of EEG data between computer and EEG receiver is accomplished by the microcontroller C8051 F320 integrated with the USB2.0 interface. Additionally, in order to achieve medical device security requirements, the highly integrated radio transceiver ADF7020 ia used in the entire system which achieves the isolation of power supply network with patients.
