Abstract

L'invention porte sur un dispositif d'examen sanguin et sur un capteur sanguin, dans lequel les parties qui sont à l'intérieur et à l'extérieur d'un corps de dispositif qui sont situées autour d'un système optique et autour d'une position de perçage ne sont pas contaminées et sont facilement et commodément utilisées par élimination du besoin de remplacement d'un élément de structure. Le dispositif d'examen sanguin est adapté pour que des ouvertures d'émission de laser (8A, 9B) du capteur sanguin (3) soient couvertes d'un film (10) qui constitue une partie de recouvrement transmettant les faisceaux laser. En outre, le dispositif d'examen sanguin comporte un premier trajet à pression négative destiné à provoquer une pression négative du côté peau du capteur sanguin (3) et comporte également un second trajet à pression négative destiné à provoquer une pression négative du côté film (10), ou du côté partie de recouvrement transmettant les faisceaux laser. La résistance du fluide dans le second trajet à pression négative est adaptée pour être inférieure à la résistance du fluide dans le premier trajet à pression négative.
