비가압 상태에서 혈압 및 맥박을 정확하게 측정한 값를 얻기 위하여 안정시 휴대성과 소형화가 가능한 자성 홀소자를 이용한 손목 착용형 맥진기의 시제품을 개발하였다. 본 시제품을 이용하여 맥진파를 분석한 13명의 임상시험 데이터로 상관인자를 정하여 혈압추정 알고리즘의 회귀식을 구하였다. 5초간 비가압 맥진기로 맥진파를 수집한 혈압추정값과 전자혈압계나 수은혈압계로 측정한 혈압값을 비교하였다. 비가압 맥진기로 추정한 최고혈압과 최저혈압의 표준편차는 혈압국제규격 허용치 범위 안에 있는 12.1과 5.9로 각각 나타났다.
In order to get the precise blood pressure and pulse number in the cuffless status, the wrist wearable pulsimeter with a portable and small size apparatus using by Hall device is developed. The regression analysis of the pulse wave measured by the testing product of pulsimeter is conducted two equations of the blood pressure algorithm. The estimated values of blood pressure obtained by the cuffless pulsimeter during 5 s are compared with the practical values measured by electronic or mercury liquid blood pressure meters. The standard deviation of the estimated value and the practical value for the high blood pressure and the low blood pressure were 12.1 and 5.9, respectively, which have the neighborhood values of BP International Standard. The detail analysis of a pulse wave measured by cuffless wrist wearable detecting the changes of the magnetic field can be used to develop a new diagnostic algorithm of blood pressure applying for oriental medical apparatus like as the wrist wearable pulsimeter.
