摘要:
针对现有连续无创血压测量系统测量结果离散程度高的问题，设计基于USB-4221数据采集卡的连续血压测量系统。通过AD8232心电传感器和指夹光电脉搏传感器同步获取心电-脉搏信号，设计心电-脉搏硬件调理电路。应用MIMIC数据库中心电-脉搏-血压信号计算脉搏传导时间，并进行回归分析，构建血压测量模型。同时，利用图形可视化工具GUI进行了用户平台的设计。系统采集了若干名志愿者的相关数据，测得的血压值与欧姆龙电子血压计HEM-8713的测量值进行对比，测量误差在±5 mmHg范围内，达到AAMI标准中对测量平均误差的要求。
Abstract:
Abstract: A continuous blood pressure measurement system based on USB-4221 data acquisition card is designed to solve the problem of high dispersion degree of measurement results in the existing continuous noninvasive blood pressure measurement system. Electrocardiogram (ECG)-pulse signals are obtained simultaneously by AD8232 ECG sensor and photoelectric finger pulse sensor, and then the corresponding hardware conditioning circuits are designed. The pulse transit time is calculated using the ECG-pulse-blood pressure signals in MIMIC database, and then is analyzed by regression analysis, thereby constructing a blood pressure measurement model. Meanwhile, GUI, a graphical visualization tool, is used to design the user platform. The relevant data of several volunteers are collected by the system. The comparison between the measured blood pressure and that obtained by OMRON electronic blood pressure meter HEM-8713 showed that the measurement error was within the range of ±5 mmHg, which reached the requirement for average error in AAMI standard.
