迄今多道生理记录仪已成为心脏介入术及医学基础研究不可缺少的重要设备。本研究首创用美国国家仪器 (NI)公司的 L ab VIEW开发系统为软件基本构架 ,自制低噪声多道前置放大器 ,配合 DAQ数据采集模块和通用计算机为开发硬件平台 ,研制了临床实用型多道心电生理记录仪。产品具有心电生理实时显示 ,数字高通、低通、5 0 Hz陷波和增益调节 ,即时存贮、任意回放和打印 ,基本程控刺激等功能。仪器小型化、经济实用、使用灵活 ,有利于心脏介入诊疗技术在医院推广和应用。
To date, multi-channel physiology recorder has become an important and indispensable equipment for cardiac interventional and medical basic research. In this study, the first LabVIEW basic system, self-made low-noise multi-channel preamplifier and DAQ data acquisition module and general-purpose computer are used to develop the hardware platform with the L ab VIEW system developed by the National Instruments Corporation. Road electrophysiology recorder. Products with real-time electrophysiological display, digital high-pass, low-pass, 50Hz notch and gain adjustment, real-time storage, any playback and printing, the basic program-controlled stimuli and other functions. Small instruments, economical and practical, flexible, conducive to cardiac interventional diagnosis and treatment technology in the hospital promotion and application.
