Abstract

L'invention concerne un procédé et un dispositif pour mesurer le taux d'au moins un constituant du sang. Le dispositif comprend une source lumineuse et un détecteur de lumière qui est placé près de la surface d'un organe. Le dispositif comprend également une paire d'amplificateurs de gain réglables (A1, A2) et un processeur/contrôleur (44) connecté à l'intérieur d'une unité de traitement. Cette dernière fonctionne de manière à séparer une composante de signal c.a. d'une composante de signal c.c. La source lumineuse comprend au moins une unité émettrice de lumière. De préférence, la source lumineuse émet la lumière en alternance dans deux gammes de longueurs d'ondes différentes et normalise les signaux de sortie c.a. et c.c. en fonction de l'intensité de la lumière réfléchie contre un organe; on calcule ensuite la proportion des signaux normalisés pour chaque gamme de longueur d'onde. Le dispositif peut déterminer le taux du constituant du sang recherché et peut utiliser ce taux pour effectuer la surveillance et/ou déclencher une alarme (48) lorsque ce taux tombe au-dessous d'un seuil prédéterminé. Le dispositif et le procédé peuvent s'appliquer, entre autres, à la surveillance d'états d'apnée, d'effort respiratoire, de flux sanguin réduit dans des zones d'organes, de fréquence cardiaque, d'ictère et de la vitesse du flux sanguin.
