Title (EN) AMBULATORY INFUSION DEVICE DRIVE CONTROL AND BLOCKAGE DETECTION
(FR) COMMANDE DE TRANSMISSION DE DISPOSITIF DE PERFUSION AMBULATOIRE ET DÉTECTION DE BLOCAGE
Abstract:
(EN) Disclosed is a method for controlling operation of an ambulatory infusion device drive (2),the ambulatory infusion device drive (2) including a spindle drive (2) with a stepper motor (21) and a rotary encoder (23) in operative coupling with the drive member, the method including repeatedly executing a drive control sequence, the drive control sequence comprising: a) actuating the stepper motor (21) to execute a requested steps number in the current drive control sequence; b) receiving a drive member position, the drive member position being indicative of an actual position of a drive member following the actuation; c) computing, from the drive member position and the requested steps number, a missed steps number as deviation between the requested steps number and an executed steps number in the current drive control sequence; d ) determine, based on a statistical evaluation of a time-distribution of the missed steps number over a history of drive control sequences, if the drive (2) is blocked. The method further including generating an blockage alarm signal if it is determined that the drive is blocked.
(FR) L'invention concerne un procédé de commande du fonctionnement d'une transmission de dispositif de perfusion ambulatoire (2), la transmission de dispositif de perfusion ambulatoire (2) comprenant une transmission de broche (2) avec un moteur pas à pas (21) et un codeur rotatif (23) en couplage fonctionnel avec l'élément de transmission, le procédé comprenant l'exécution répétée d'une séquence de commande de transmission, la séquence de commande de transmission comprenant : a) l'actionnement du moteur pas à pas (21) pour exécuter un certain nombre d'étapes demandées dans la séquence de commande de transmission actuelle ; b) recevoir une position d'élément de transmission, la position d'élément de transmission indiquant une position réelle d'un élément de transmission suite à l'actionnement ; c) calculer, à partir de la position de l'élément de transmission et du nombre d'étapes demandées, un nombre d'étapes manquées en tant qu'écart entre le nombre d'étapes demandées et un nombre d'étapes exécutées dans la séquence de commande de transmission actuelle ; d ) déterminer, sur la base d'une évaluation statistique d'une distribution temporelle du nombre d'étapes manquées sur un historique de séquences de commande de transmission, si la transmission (2) est bloquée. Le procédé comprend en outre la génération d'un signal d'alarme de blocage s'il est déterminé que la transmission est bloquée.
