Multi Physiological Parameters Collecting System for Research on Veracity of Blood Pressure Measurement by Pulse Wave Transmit Time
摘要
Abstract
Objective To design a system in order to do research on the veracity of blood pressure measurement used pulse wave transmit time (PWTT) method. Methods Some factors that could affect the veracity of blood pressure measurement using PWTT were analyzed, the system that could collect multi physiological parameters, the module that could be used for the individual calibration of blood pressure measurement, and also the data interface that could be connected seamlessly with the DSP arithmetic module were designed. Results Two methods were used to calculate the PWTT. The results of 20 times measurement experiment indicated that the signal quality of multi physiological parameters was very good, after simple filter, the feature points could be located accurately, and the PWTT was easy to be calculated for algorithm study. The system also provided seamless interface to the DSP board, which could be used to build the experiment system. Conclusion The system proposed can be used to do the research on the veracity of blood pressure measurement by PWTT method. [Chinese Medical Equipment Journal,2012,33(4) ;28-29,51]关键词
