Abstract

Abrégé descriptif : L’invention concerne un appareil de détermination du taux d’hématocrite et/ou du taux d’hémoglobine d’un liquide en circulation dans une portion tubulaire (2), comprenant : deux ensembles émetteur-récepteur (10 ; 20), chaque ensemble émetteur-récepteur (10 ; 20) comprenant une source lumineuse (11 ; 21) et un capteur lumineux (12 ; 22) prévus pour être agencés de part et d’autre de la portion tubulaire (2) au niveau d’une zone de circulation du liquide pour une mesure en transmission ; la source lumineuse (11 ; 21) de chacun des deux ensembles émetteur-récepteur (10 ; 20) étant configurée pour émettre des faisceaux lumineux selon une longueur d’onde d’émission choisie pour correspondre à un point isobestique de l’hémoglobine ; chaque ensemble émetteur-récepteur (10 ; 20) comprenant en outre un système de collimation (13 ; 23) du faisceau lumineux émis depuis la source lumineuse (11 ; 21) correspondante en direction du capteur lumineux (12 ; 22) correspondant. Figure de référence : figure 6Abstract: The invention relates to an apparatus for determining the hematocrit level and/or the hemoglobin level of a liquid circulating in a tubular portion (2), comprising: two transmitter-receiver assemblies (10; 20), each transmitter-receiver assembly (10; 20) comprising a light source (11; 21) and a light sensor (12; 22) intended to be arranged on either side of the tubular portion (2) at a liquid circulation zone for a transmission measurement; the light source (11; 21) of each of the two transmitter-receiver assemblies (10; 20) being configured to emit light beams according to an emission wavelength chosen to correspond to an isosbestic point of the hemoglobin; each transmitter-receiver assembly (10; 20) further comprising a collimation system (13; 23) of the light beam emitted from the corresponding light source (11; 21) towards the corresponding light sensor (12; 22).
