摘　　要：介绍一种非侵入性胃运动功能检测系统。体表胃电图(EGG)测量无创,无害,廉价,操作简单。利用前置放大器和滤波器有效滤除掉呼吸,心电,人体等干扰。用单片机采集到的数据经传输到PC机存储和处理,并通过通用串行总线USB来通信。可利用数字滤波和小波变换的方法对其提取的胃电信号分析和处理。A non-invasive measuring system is developed for the assessment of gastric evacuation. The measurement of EGG is no-wounded, no-hurt, cheap and easy-to-operate. Preamplifier and filter were used for cancellation of respiratory ECG, body interference. The system uses singlechip to collect date and transfer to PC to store and handle through serial bus USB for communication. The method of digital filter and wavelet transform were also used for analyzing and dealing with the signal.
