Abstract

Cette invention concerne un dispositif d'insertion (10) permettant l'implantation transcutanée d'un détecteur (12), tel qu'un détecteur de glucose, dans un site déterminé à l'intérieur du corps du patient. Ce dispositif d'insertion (10) comprend une aiguille d'insertion (14) passant au travers d'une base de support (34), laquelle est conçue de manière à pouvoir se fixer sur la peau d'un patient. Un détecteur (12), se présentant sous la forme d'un film fin et flexible, comprend une partie proximale (20), laquelle est montée sur la base de support (34) et peut être reliée par connexion électrique à un moniteur adéquat, ainsi qu'une partie distale (16) dépassant de la base de support (34) et équipée d'électrodes de détection (18) en vue de l'implantation transcutanée. La partie distale (16) du détecteur (12) et la partie distale (66) de l'aiguille d'insertion (14) sont placées à l'intérieur d'une canule flexible (15) dépassant de la base de support (34). Lorsque l'on place la base de support (34) sur la peau du patient, l'aiguille d'insertion (14) perce alors la peau et entraîne l'implantation transcutanée de la canule (15) contenant le détecteur (12).
