Title
(EN) CONTINUOUS ANALYTE SENSOR WITH MAGNETIC ACTIVATION
(FR) CAPTEUR D'ANALYTE CONTINU À ACTIVATION MAGNÉTIQUE
Abstract
(EN)
Disclosed is an analyte measurement kit (1), with: a) a sensor assembly (100), the sensor assembly (100) including a transcutaneous sensor element (110) and a control unit (120); the control unit (120) including a battery (121) for powering the sensor assembly (100) and a magnetic sensor (122) designed to generate an electrical activation signal in dependence of a magnetic field, wherein the control unit (120) is designed to switch from a pre-operative state into an operative state upon generation of the activation signal; b) an insertion device (200), wherein the insertion device (200) and the sensor assembly (100) comprise complementary coupling structures (130, 230) for releasable coupling; wherein the insertion device (200) is designed for executing an insertion routine, the insertion routine including advancing the sensor assembly (100) from a retracted position where the transcutaneous sensor element (100) stands back behind a skin contact surface (220) of the insertion device (200) into an advanced position where the sensor element (100) projects beyond the skin contact surface (220), and subsequently decoupling the insertion device (200) from the sensor assembly (100). The insertion device (200) includes an activation magnet (240) and executing the insertion routine is associated with a change of a magnetic coupling between the activation magnet (240) and the sensor assembly (100), thereby generating the activation signal.

L'invention concerne un kit de mesure d'analyte (1) qui comprend : a) un ensemble capteur (100), l'ensemble capteur (100) comprenant un élément de capteur transcutané (110) et une unité de commande (120); l'unité de commande (120) comprenant une batterie (121) pour alimenter l'ensemble capteur (100) et un capteur magnétique (122) conçu pour générer un signal d'activation électrique en fonction d'un champ magnétique, l'unité de commande (120) étant conçue pour passer d'un état de pré-fonctionnement à un état de fonctionnement lors de la génération du signal d'activation; et b) un dispositif d'insertion (200), le dispositif d'insertion (200) et l'ensemble capteur (100) comprenant des structures de couplage complémentaires (130, 230) pour un couplage amovible; le dispositif d'insertion (200) étant conçu pour exécuter un programme d'insertion, le programme d'insertion consistant à faire avancer l'ensemble capteur (100) d'une position rétractée dans laquelle l'élément de capteur transcutané (100) se dresse derrière une surface de contact cutané (220) du dispositif d'insertion (200) dans une position avancée dans laquelle l'élément de capteur (100) fait saillie au-delà de la surface de contact cutané (220), avec pour corollaire le découplage du dispositif d'insertion (200) de l'ensemble capteur (100). Le dispositif d'insertion (200) comprend un aimant d'activation (240) et l'exécution du programme d'insertion est associée à un changement de couplage magnétique entre l'aimant d'activation (240) et l'ensemble capteur (100), générant ainsi le signal d'activation.
