Title
(EN) FLUID INFUSION SYSTEM THAT AUTOMATICALLY DETERMINES AND DELIVERS A CORRECTION BOLUS
(FR) SYSTÈME DE PERFUSION DE FLUIDE QUI DÉTERMINE ET DÉLIVRE AUTOMATIQUEMENT UN BOLUS DE CORRECTION
Abstract
(EN)
A method of controlling an insulin infusion device involves controlling the device to operate in an automatic basal insulin delivery mode, obtaining a blood glucose measurement for the user, and initiating a correction bolus procedure when: the measurement exceeds a correction bolus threshold value; and a maximum basal insulin infusion rate is reached during the automatic basal insulin delivery mode. The correction bolus procedure calculates an initial correction bolus amount, and scales the initial amount to obtain a final correction bolus amount, such that a predicted future blood glucose level resulting from simulated delivery of the final correction bolus amount exceeds a low blood glucose threshold level. The final amount is delivered to the user during operation in the automatic basal insulin delivery mode.

Procédé de commande d'un dispositif de perfusion d'insuline qui consiste à commander le dispositif pour qu'il fonctionne dans un mode de distribution automatique d'insuline basale, obtenir une mesure de la glycémie de l'utilisateur et lancer une procédure de bolus de correction lorsque : la mesure dépasse une valeur seuil pour bolus de correction ; et une vitesse maximale de perfusion d'insuline basale est atteinte pendant le mode de distribution automatique d'insuline basale. La procédure de bolus de correction calcule une quantité de bolus de correction initiale, et met à l'échelle la quantité initiale pour obtenir une quantité de bolus de correction finale, de telle sorte qu'un taux de glycémie futur prédit résultant de l'administration simulée de la quantité de bolus de correction finale dépasse un niveau de seuil de glycémie bas. La quantité finale est administrée à l'utilisateur pendant le fonctionnement dans le mode de distribution automatique d'insuline basale.
