Abstract

Une sonde ou tête de mesure 10 à stabilisation thermique, destinée à effectuer des mesures transcutanées simultanées de la concentration en gaz du sang ainsi que du niveau de la circulation du sang dans l'objet des mesures 1 000, est équipée de moyens d'émission et de réception de la lumière 104 à 110, disposés de telle manière que le trajet de la lumière ne passe que par l'objet des mesures. Application : mesure, non seulement de la concentration globale e de l'oxygène, mais aussi de la concentration due à la combinaison chimique avec la seule hémoglobine, et détermination de la courbe de variation du pouls ou du niveau de la circulation du sang dans les capillaires, ou de l'élasticité des capillaires parcourus par le sang.
