Abstract

L'invention concerne un appareil de capteur d'intervention sous-cutané, comprenant une base de montage (10), un dispositif d'insertion (20) et un capteur (30). Le dispositif d'insertion est relié de manière amovible à la base de montage, le dispositif d'insertion est orienté de telle sorte que le dispositif de montage soulève la peau (100) située sous la base de montage pour former un angle d'implantation approprié, et le dispositif d'insertion implante une partie de détection d'électrode (31) du capteur dans un tissu sous-cutané. L'appareil de capteur peut non seulement ajuster commodément l'angle et la profondeur dudit capteur lorsque celui-ci est implanté dans différentes parties du corps et assurer la précision et la stabilité de la surveillance des données, mais il peut également être utilisé avec des capteurs d'implant de différentes longueurs dans un site de tissu sous-cutané prédéterminé sans percer de couche musculaire. L'invention concerne en outre un procédé d'implantation pour l'appareil de capteur d'intervention sous-cutané, un procédé et un système de surveillance. Selon le système et le procédé de surveillance, un signal d'objet mesuré est surveillé en temps réel à l'aide d'un capteur d'intervention, et des données de signal sont transmises à un terminal d'affichage pour aider un utilisateur à visualiser les données de surveillance en temps réel.
