Abstract

L'invention concerne un dispositif servant à la détermination optique de variables physiologiques dans des tissus perfusés. Le dispositif présente une première et une seconde sources lumineuses émettant respectivement un faisceau lumineux d'une première ou d'une seconde longueurs d'ondes prédéterminées. Les sources lumineuses sont disposées de telle façon que le faisceau lumineux provenant de ces sources puisse pénétrer dans le tissu perforé. On utilise au moins un photodétecteur disposé de manière à détecter la lumière émise par les sources lumineuses et rétrodiffusée par le tissu perfusé ou traversant ce dernier. Le dispositif présente en outre une unité de commande fournissant des signaux de commande aux sources lumineuses de façon que lesdites sources émettent une lumière en continu, alternativement les unes par rapport aux autres, cependant que dans ce processus, une ou plusieurs phases obscures peuvent être introduites, phases dans lesquelles au moins une source lumineuse n'émet aucune lumière. Un dispositif d'évaluation est connecté avec une sortie du photodétecteur et fournit, pour au moins une variable physiologique à mesurer, un signal de sortie décelable à une interface pouvant être liée avec le dispositif d'évaluation.
