IMP900心电呼吸通气量监测系统的研制

Development of the IMP900 ECG & V_T Patient Monitoring System

研制了一套新型的呼吸监测系统。它基于阻抗法，实现了对呼吸潮气量的无创连续监测，并具有心电监测功能。系统采用了先进优良的数字存储示波技术，其硬件构成模块化，通过引入逐个定标的方法，克服了测量呼吸潮气量的个体差异，使阻抗法测量呼吸通气量成为实际可行。整体仪器具有性能价格比高的特点。该系统已进行了非手术病人的初步临床实验，结果表明该系统能基本满足临床要求，可望在临床中得到广泛应用。

A new respiration monitor was developed with this paper. which can monitor tidal volume continuously based on the impedance technique as well ad ECG at the same time. Advanced digital storage display technique and modular hardware design are adopted in this system. One by one calibration method was introduced to solve problem of individual differences in the measurement of tidal volume, vhich make it viable to monitor Tidal volume with impedance technique. The system possesses characteristic of high ratio of Performance to cost. Clinica1 tests of the system have been made for nonsurgical patients,the results show that the system meets the basic clinical requirements. and its wide clinical applications are expected in the future.
