Title (EN) MONITORING APPARATUS FOR MONITORING BLOOD PRESSURE OF A SUBJECT
(FR) APPAREIL DE SURVEILLANCE POUR SURVEILLER UNE PRESSION SANGUINE D'UN SUJET
Abstract:
(EN) A monitoring apparatus for monitoring a blood pressure information of a subject is disclosed. The monitoring apparatus comprises an ultrasound transducer for emitting ultrasound waves to a volume of the subject that includes a blood vessel and for receiving ultrasound waves from said volume of the subject, and for providing a first signal on the basis of ultrasound waves received from the volume of the subject. A light source is included for emitting light to the subject and a light sensor is included for detecting light received from the subject and for providing a second signal on the basis of the light received from a skin of the subject. The monitoring apparatus comprises a processing unit for determining: i) a time of arrival of a cardiac pulse in the blood vessel based on the first signal, ii) a point in time when the cardiac pulse reaches the skin of the subject based on the second signal, iii) a pulse transit time between the time of arrival of the cardiac pulse in the blood vessel and the point in time when the cardiac pulse reaches the skin of the subject; and iv) the blood pressure based on the pulse transit time.
(FR) L'invention concerne un appareil de surveillance pour surveiller des informations de pression sanguine d'un sujet. L'appareil de surveillance comprend un transducteur ultrasonore pour émettre des ondes ultrasonores vers un volume du sujet qui comprend un vaisseau sanguin et pour recevoir les ondes ultrasonores provenant dudit volume du sujet, et pour fournir un premier signal sur la base d'ondes ultrasonores reçues en provenance du volume du sujet. Une source de lumière est incluse pour émettre de la lumière vers le sujet, et un capteur de lumière est inclus pour détecter la lumière reçue en provenance du sujet et pour fournir un second signal sur la base de la lumière reçue en provenance de la peau du sujet. L'appareil de surveillance comprend une unité de traitement pour déterminer : i) un temps d'arrivée d'une impulsion cardiaque dans le vaisseau sanguin sur la base du premier signal, ii) un point dans le temps lorsque l'impulsion cardiaque atteint la peau du sujet sur la base du second signal, iii) un temps de transit d'impulsion entre le temps d'arrivée de l'impulsion cardiaque dans le vaisseau sanguin et le point dans le temps lorsque l'impulsion cardiaque atteint la peau du sujet; et iv) la pression sanguine sur la base du temps de transit d'impulsion.
