基于示波法的电子血压计设计与实现
Design and Implementation of an Oscillography Based Electronic Blood Pressure Meter
摘要
Abstract
Complex hardware and strong noisy are easily lead poor accuracy and low coherence in traditional blood pressure(BP) meter.To address such problems,an electronic BP meter based on oscillography is proposed.The hardware consists of a STM32 microcontroller and few external circuits,meanwhile,digital signal processing,such as digital filtering;Blood pressure calculation and analysis are based on the two order Gauss fitting,and variable coefficient method were used in the prototype.10 volunteers were participated in the test.The average error and standard deviation of systolic blood pressure are 2.6 mmHg and 2.2 mmHg,respectively;and the average error and standard deviation of diastolic blood pressure are 2.0 mmHg and 1.6 mmHg,respectively.The accuracy is significantly higher than the United States ANSI/AAMI SP10—1992 blood pressure measurement standard.关键词
