Abstract

A new microcomputerized Fetal Electrocardiograph (FECG) is presented in this paper. A two-grade configuration (front-end & back-end) is designed for the instrument. The front-end processor is based on a Digital Signal Processor (DSP) TMS32010 and the Adaptive Noise Cancelling (ANC) algorithm to extract FECG with non-invasive method. The processed results are sent to the back-end personal computer for real time display, analysis and record. Clinical tests show the instrument is designed smartly and operated easily, and can be applied widely to many medical situations.

摘要

本文介绍了一种新型的微机化胎儿心电图仪（FECG）。该仪器采用两级配置（前端和后端）进行设计。前端处理器基于数字信号处理器（DSP）TMS32010，并采用自适应噪声消除（ANC）算法以非侵入性方法提取胎儿心电图。处理后的结果被发送到后端个人计算机进行实时显示、分析和记录。临床试验表明，该仪器设计精巧、操作简便，可广泛应用于多种医疗场景。
