Abstract: Disclosed herein are systems and methods for mitigating the risk of insulin stacking in automated insulin delivery systems. In AID systems configured to both automatically calculate insulin delivery based on glucose levels and receive manual programming of meal boluses configured to counteract carbohydrates in a meal, insulin stacking can result if the system automatically increases insulin delivery based on a rise in glucose levels in response to consumption of a meal and the user later programs a meal bolus for the meal. The risk of such double dosing is mitigated by the systems and methods disclosed herein by enabling the system to account for recent automated insulin increases when a meal bolus is programmed.

Abstract: Apparatuses and methods for transitioning to sleep mode or otherwise modified glucose target range in automated insulin delivery systems. For example, sleep mode can include a lower glucose target and/or lower and narrower glucose target range because of fewer variables that affect glucose values during sleep such as eating and exercise. Due to increased stability provided by the sleep mode target range, it is desirable to transition to the sleep mode target range as quickly as possible, while ensuring the transition is done safely and does not risk low glucose or hypoglycemia by too quickly switching to the lower and narrower target range. Systems and methods disclosed herein therefore provide various approaches for safely and quickly transitioning to sleep mode or other modified target ranges in order to improve time in range by being more aggressive to get to the lower sleep mode or other target faster without risking hypoglycemia.

Abstract: An alternate mode for addressing meals in closed loop insulin delivery systems is disclosed. An Eating Soon Mode may be a user-selectable feature that can be activated when a user anticipates eating a meal in the near future. Once activated, Eating Soon Mode preemptively modifies the closed loop algorithm in preparation for the expected rise in glucose levels from consumption of the meal. This can result in a greater amount of time in range for the user, a lower coefficient of variation of the user's glucose levels and/or a lower maximum BG level for the user. According to embodiments disclosed herein, activation of Eating Soon Mode modifies the algorithm to deliver a correction bolus to lower the user's glucose level and to provide a modified, lower target range at which to maintain the user's glucose levels in anticipation of the glucose rise that will result from the meal.

Abstract: Disclosed herein are systems and methods for automated insulin delivery that provide an Alternate Normal Activity Mode that has a lower and narrower target range than the standard range employed in Normal Mode. The Alternative Normal Mode can be a user-selectable feature that provides more aggressive glucose level control that is designed to decrease hyperglycemia without significantly increasing the risk of hypoglycemia. For example, Normal Mode may employ a standard glucose range between which the closed loop algorithm attempts to maintain the user's glucose levels such as 112.5 mg/dL to 160 mg/dL and Alternative Normal Mode may employ a lower and narrower range such as 90 mg/dL to 130 mg/dL. Alternative Normal Mode can also employ a lockout feature that is activated when glucose is high, but is falling rapidly.

Abstract: A battery-powered infusion pump for delivery of insulin or other medicament may collect and store data related to the pump. The infusion pump can communicate some or all of the stored data to another device, and control the timing and amount of data communicated in order to conserve battery life.
