Abstract

Amélioration apportée à la construction d'un appareil utilisé comme instrument permettant d'effectuer la mesure transcutanée de la concentration ou de la pression en oxygène du sang artériel. La surface de la peau peut être chauffée uniformément, ce qui conduit à une mesure stable très précise. La zone de contact entre la surface de la peau et la membrane d'électrode 5 est petite, c'est-à-dire que la peau peut être couverte par le corps chauffant 10 qui s'avance vers la cathode 1. De cette façon la peau ne s'élève pas notablement dans la membrane d'électrode faisant face à l'ouverture 11. Ainsi la membrane d'électrode 5 n'est pas déplacée, c'est-à-dire que l'épaisseur de la couche de l'électrolyte 8 est pratiquement inchangée, ce qui a pour effet de permettre une grande précision de la mesure. Application aux instruments médicaux.An improvement in the construction of an apparatus used as an instrument for performing the transcutaneous measurement of arterial blood oxygen concentration or pressure. The surface of the skin can be heated evenly, which leads to a very precise stable measurement. The area of contact between the surface of the skin and the electrode membrane 5 is small, i.e. the skin can be covered by the heating body 10 which advances towards the cathode 1. In this way. the skin does not rise significantly in the electrode membrane facing the opening 11. Thus the electrode membrane 5 is not displaced, i.e. the thickness of the layer of the electrolyte 8 is practically unchanged, which has the effect of allowing high measurement precision. Application to medical instruments.
