A clip-type pulsimeter using a permanent magnet and Hall device can reliably measure pulse wave velocity, suggesting its potential utility as a diagnostic device for predicting atherosclerosis.
May support portable PWV devices in research settings; leaves open clinical validation for atherosclerosis prediction.
영구자석과 홀소자로 구비된 집게형 맥진기를 이용하여 목 부위의 경추동맥의 맥진파형과 손목 부위의 요골동맥 맥진파형을 각각 측정하였다. 두 개의 맥진파형을 비교하여 얻은 맥파전달시간과 맥파전달속도를 분석하였다. 맥파전달속도는 기존의 방식으로 측정한 값과 유사한 약 8.5 m/s으로 나타났다. 재현성과 신뢰성이 있는 한방의료기기인 집게형 맥진기로 얻은 맥파전달속도를 기준하여 동맥경화도를 예측할 수 있음을 제시하였다. The pulse waveforms of a carotid artery in the neck and a radial artery in the hand wrist were individually measured by using clip-type pulsimeter equipped with a permanent and Hall device. The pulse transit time and the pulse wave velocity obtained through comparison of two pulse waveforms were analyzed each other. A value of the pulse wave velocity was about 8.5 m/s similar to one measured by a conservative method. This result suggests that the clip-type pulsimeter as the reproducible and reliable one oriental diagnostic medical device can be predicted to any atherosclerosis state in the cardiac circulatory system.
