胎儿心电微机监护装置

Fetal ECG Monitoring System Based on MCU Processing

为了对孕妇产程中的胎儿进行有效的电子监护 ,研究了基于胎儿头皮心电信号特征 ,利用自适应抵消器和斜率峰值双阈值检测技术对信号进行了处理 ,采用可变积分器来排除因导联切换 ,导联脱落所引起的基线漂移 ,设计了基于Cygnal公司C80 5 1F0 2 0单片机的胎儿心电内监护装置。

In order to monitor the fetus in labor, the signal chara ct eristic from fetal scalp electrode is researched, An adaptation algorithm and a peak to peak detecting technology are adopted in signal processing, and an adaptation gain c ont rol method is used to eliminate disturber from base-line shift. A fetal ECG mon itoring system is designed on the basis of C8051F020 MCU.
