Abstract

L'invention concerne un système de capteur à invasion minimale pour la détermination de la concentration de substances dans le corps humain. On utilise de tels systèmes de capteur dans le diagnostic médical, par exemple pour déterminer la concentration de glucose dans le sang ou dans le liquide interstitiel lors du traitement des diabétiques. Le système de capteur selon l'invention comporte une sonde cannelée (3), disposée sur un support (2), pour prélever un liquide dans des tissus. Le support comporte, en outre, un capteur (S) comportant un élément détecteur et un canal d'écoulement en contact avec l'élément détecteur et raccordé directement à l'intérieur de la sonde cannelée (3). Le raccord peut également se faire à l'aide d'un raccord creux (4). On utilise, pour la sonde cannelée (3), le raccord creux (4) et le capteur (S), des éléments microfluidiques de manière à obtenir des mesures directes et continues, par le capteur (S), des concentrations de substances dans les liquides prélevés dans le tissu au moyen de la sonde cannelée (3).
