Abstract

One prototype product of clip-type pulsimeter equipped with magnetic field sensing semiconductor Hall device after one permanent magnet attached "Chwan" position in center of a radial artery was developed. The clip-pulsimeter was composed of the hard ware system measuring to voltage signals. To measure the blood velocity, the radial artery pulsimeter is simultaneously connected the PPG (photoplethysmograph). Analysis and comparison of two pulse waves data has done obtained from a clinical test of forty subjects of 20 ages. The value of a blood velocity simultaneously measured from a radial artery puls wave and PPG is an average value of 0.8m/s. The usage of this research results is possible to store the biomedical signals for health care.

요골동맥의 중심인 "관" 위치에 영구자석을 붙인 후 바로 위쪽에 자성측정용 반도체 홀소자를 장착하여 전압 신호를 검출하는 하드웨어 시스템이 적용된 집게형 맥진기 시제품을 개발하였다. 집게형 맥진기와 용적맥파계를 동시 분석하는 시스템으로 20대 나이 임상참가자 40명 각각에 대한 맥진파형과 용적맥파형 두 피크값을 비교 측정한 결과 혈류속도가 평균 0.8 m/s로 기존 값과 거의 비슷하였다. 이로써 요골동맥파형-용적맥파형을 환자감시장치에서 제시하는 주요 임상의 주요값으로 적용할 수 있음을 제시하였다.
