摘要
本文介绍一种微机化胎儿心电图仪。它采用前后台机结构,前端机以TMS32010数字信号处理器为核心,采用自适应噪声抵消软件算法,无创无损提取胎儿心电信号,并通过通讯接口送至后台微机实时显示,分析和记录处理结果。临床试验表明仪器设计合理,操作简便,可灵活应用于多种场合。
A new microcomputerized Fetal Electrocardiograph (FECG) is presented in this paper. A two-gradeconfiguration (front-end & back-end)is designed for the instrument. The front-end processor is based on aDigital Signal Processor (DSP) TMS32010 and the Adaptive Noise Cancelling (ANC)algorithm to extract FECGwith non-invasive method. The processed results are sent to the back-end personal computer for rea1 time display, analysis and record. Clinical tests show the instrument is designed smartly and operated easily, and can beapplied widely to many medical situations.
