摘要：
PURPOSE: A pulse diagnosis method using a wrist wearable pulse diagnostic device with a hall sensor is provided to easily locate a feature point of a pulse wave signal by analyzing a pulse wave signal measured from a radial artery of a body through first to third order differentiation processing.CONSTITUTION: A pulse wave is measured from a radial artery of a body (S110). The pulse wave signal is amplified (S120). Noise is removed from the amplified pulse wave signal (S130). The filtered pulse wave signal is amplified through non-inverting amplification (S140). The pulse wave signal is converted from an analog signal to a digital signal (S150). Overlapping noise is removed from the pulse wave signal converted into a digital signal (S160). A section is set up according to a cycle of the pulse wave signal by processing the pulse wave signal with first order differentiation (170). A feature point of the pulse wave signal is obtained (S180). A reflective point of the pulse wave signal is obtained (S190). A dicrotic notch of the pulse wave signal is obtained (S200).COPYRIGHT KIPO 2013[Reference numerals] (S110) Pulse wave signal measuring step (S120) Pulse wave signal firstly amplifying step (S130) Pulse wave signal firstly filtering step (S140) Pulse wave signal secondly amplifying step (S150) Pulse wave signal converting step (S160) Pulse wave signal secondly filtering step (S170) Pulse wave signal section setting step (S180) Pulse wave signal feature point drawing step (S190) Pulse wave signal reflective point drawing step (S200) Pulse wave signal dicrotic notch drawing step본 발명은 집게형의 손목 착용형 맥진기를 통해 인체 요골동맥의 맥파 신호를 측정한 후 이를 1~3차 미분 가공을 통해 분석하여 맥파신호의 특징점 위치를 찾고, 해당 데이터들을 저장해 이를 맥진에 활용하여 보다 정확한 맥진을 할 수 있도록 하는 홀센서가 이용되는 손목 착용형 맥진기를 이용한 맥진방법에 관한 것으로서, 본 발명은 맥파 신호 측정단계, 맥파 신호 1차 증폭단계, 맥파 신호 1차 필터링 단계, 맥파 신호 2차 증폭단계, 맥파 신호 변환단계, 맥파 신호 2차 필터링 단계, 맥파 신호 구간 설정단계, 맥파 신호 특징점 도출 단계, 맥파 신호 반사점 도출 단계, 맥파 신호 절흔점 도출단계를 포함하여 구성되고, 이러한 구성을 통해 집게형맥진기를 손목에 착용하여 맥진기의 맥파감지부를 통해 인체 요골동맥의 맥파
