Abstract

Dispositif de dosage de la glycémie comprenant une source de lumière (3) pour la production d'un rayonnement de mesure destiné à irradier une partie (2) du corps à une longueur d'onde à laquelle les caractéristiques optiques de la partie du corps (2) dépendent de la concentration du constituant sanguin en question, un photodétecteur (10) pour la détection du rayonnement de mesure atténué dans ladite partie (2) du corps en fonction de la concentration, ainsi qu'une unité d'évaluation (12) pour l'évaluation de la concentration dudit constituant sanguin en fonction du rayonnement de mesure détecté, la partie du corps (2) irradiée étant un oeil (2) et le photodétecteur (10) pour la mesure de la réflexion du faisceau lumineux étant placé dans la trajectoire du rayonnement réfléchi ou rétrodiffusé dans la chambre antérieure (1) de l'oeil. Un système de focalisation (6) est monté entre la source de lumière (3) et l'oeil (2) irradié pour empêcher que la rétine ne soit endommagée par le rayonnement de mesure. Ce système de focalisation concentre ledit rayonnement de mesure dans la chambre antérieure (1) de l'oeil, de sorte que le rayonnement du côté de la rétine soit arrêté essentiellement par l'iris (7) et/ou que la longueur d'onde dudit rayonnement se trouve dans la plage d'absorption de l'humeur aqueuse afin que la rétine ne soit pas endommagée par celui-ci.
