Abstract: front page image
(EN)The present invention relates to a method and device for improving the accuracy of wrist blood pressure measurement in an e-health terminal using multiple biological signal measurements, wherein the accuracy of blood pressure measurement at the wrist is improved by simultaneously measuring and analysing an oscillation component of the blood pressure together with representative factors that affect blood pressure in order to improve the ease and accuracy of measurement. In the present invention, in the same way as with an oscillometric electronic sphygmomanometer, pressure is applied to the wrist of the person being tested and the artery is closed by using a cuff and then the amplitude of oscillation, which is a vibrational characteristic, occurring at the cuff is detected such that the systolic blood pressure, the diastolic blood pressure and the mean blood pressure are determined, and the systolic blood pressure, the diastolic blood pressure and the mean blood pressure determined in this way are compensated by using the pulse transit time (PTT), the time between the maximum increase point and the highest point in Korotkoff power (kmax-rip), the body mass index (BMI) and the arm circumference (Armc); and the pulse transit time (PTT), the time between the maximum increase point and the highest point in Korotkoff power (kmax-rip), the body mass index (BMI) and the arm circumference (Armc) are determined by electronically measuring changes in the Korotkoff sound at the wrist while detecting the amplitude of oscillation at the cuff, and at the same time detecting an electrocardiogram and PPG.
(FR)La présente invention concerne un procédé et un dispositif permettant d'améliorer la précision de la mesure de la pression artérielle au niveau du poignet associée à un terminal de cybersanté grâce au recours à la mesure de multiples signaux biologiques, la précision de la mesure de la pression artérielle au niveau du poignet étant améliorée grâce à la mesure et à l'analyse simultanées d'un composant de nature oscillatoire de la pression artérielle, ainsi que de facteurs représentatifs ayant une influence sur la pression artérielle afin d'améliorer la facilité et la précision de la mesure. Dans la présente invention, de la même façon qu'avec un tensiomètre oscillométrique électronique, une pression est appliquée sur le poignet de la personne devant faire l'objet de la mesure et l'artère est fermée au moyen d'un brassard, puis l'amplitude de l'oscillation, qui est une caractéristique vibrationnelle, intervenant au niveau du brassard est détectée de façon à déterminer la pression artérielle systolique, la pression artérielle diastolique et la pression artérielle moyenne, la pression artérielle systolique, la pression artérielle diastolique et la pression artérielle moyenne ainsi déterminées étant corrigées au moyen du temps de transit du pouls, de la durée s'écoulant entre le point d'augmentation maximal et le point le plus élevé de l'intensité des bruits de Korotkoff (kmax-rip), l'indice de masse corporelle (IMC) et la circonférence du bras (Armc). Le temps de transit du pouls, la durée s'écoulant entre le point d'augmentation maximal et le point le plus élevé de l'intensité des bruits de Korotkoff (kmax-rip), l'indice de masse corporelle (IMC) et la circonférence du bras (Armc) sont déterminés par une mesure électronique des modifications des bruits de Korotkoff au niveau du poignet associée à une détection de l'amplitude d'oscillation au niveau du brassard, ainsi qu'à un électrocardiogramme et à une photopléthysmographie.
(KO)본 발명은 측정의 편의성 및 정확성을 향상시키기 위해 혈압의 오실레이션 성분과 함께 혈압에 영향을 주는 대표적인 인자들에 대한 동시 측정 및 분석을 함으로써 손목에서의 혈압 측정의 정확도의 향상을 가져오는, 다중 생체 신호 측정을 이용한 E-health 단말기에서의 손목혈압 측정의 정확도를 향상시키는 방법 및 그 장치에 관한 것이다. 본 발명은, 오실로메트릭 전자혈압계와 같이, 커프를 사용하여 피검자의 손목 압력을 가해 동맥을 폐색시킨 후 감압하면서 커프에 발생하는 진동 특성인 오실레이션(oscillation)의 폭을 검출하여 수축기 혈압, 이완기 혈압, 평균혈압을 구하고, 이렇게 구하여진 수축기 혈압, 이완기 혈압, 평균혈압을 맥파 전달 시간(PTT), 코르트코프 파워의 최대 증가점과 최고점 사이의 시간(kmax-rip), 체질량지수(BMI), 팔둘레(Armc)을 사용하여 보정하되, 맥파 전달 시간(PTT), 코르트코프 파워의 최대 증가점과 최고점 사이의 시간(kmax-rip), 체질량지수(BMI), 팔둘레(Armc)는 커프에서 오실레이션의 폭을 검출함과 동시에 손목에서의 코르트코프 음의 변화를 전기적으로 측정하며, 동시에 심전도, PPG를 검출하여 구하여진다.
