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.A thermally stabilized measuring probe or head 10, intended to perform simultaneous transcutaneous measurements of the blood gas concentration as well as the level of blood circulation in the object of the measurements 1000, is equipped with emission means. and light receiving 104 to 110, arranged so that the light path passes only through the object of the measurements. Application: measurement, not only of the global concentration e of oxygen, but also of the concentration due to the chemical combination with the only hemoglobin, and determination of the curve of variation of the pulse or of the level of blood circulation in the capillaries, or the elasticity of the capillaries traversed by the blood.
