Abstract: Disclosed herein are apparatuses and methods that account for meal announcements in closed loop insulin delivery systems. Rather than simply increasing an insulin delivery rate in response to the meal announcement, the closed loop algorithm can be modified to increase the insulin on board tolerance during eating periods. This approach utilizes the stability of the cascaded loop in the closed loop algorithm to prevent the oscillations in glucose levels that can occur by simply increasing the basal rate.

Abstract: Disclosed herein are apparatuses and methods incorporating an infusion pump and a CGM that can include software that automatically populates a blood glucose section of a bolus calculator with a most recent valid CGM value. The software can additionally be programmed to automatically populate the bolus calculator with a single CGM reading only when one or more predefined conditions are met that aid in mitigating the risk of inaccurate and/or invalid single CGM readings.

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: Disclosed herein are apparatuses and methods that can simplify delivery of meal boluses in diabetes therapy. Rather than requiring a user to enter a number of carbohydrates for a given meal, the system can automatically provide a predetermined amount of insulin when the user indicates that a meal is going to be consumed. Providing such predetermined, fixed meal boluses provides a lower cognitive burden alternative for the mealtime experience.

Abstract: Disclosed herein are systems and methods for automated insulin delivery that provide for adaptive closed loop control that can modify the stored basal profile used by the closed loop algorithm to better reflect the user's actual needs. Actual delivery rates calculated by the closed loop algorithm can be compared to the user's stored profile. If the differences between the actual delivery rates and the stored profile are statistically significant, the stored profile can be modified.

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: Disclosed herein are apparatuses and methods that can provide a delayed bolus calculator for use in closed loop diabetes therapy that can account for additional factors not taken into account in regular meal bolus calculations when a user wants to deliver a meal bolus a period of time after a meal was consumed. A delayed bolus calculator can enable the user to enter a period of time since the meal was consumed in addition to the number of carbohydrates consumed in a meal. This enables the system to account for the amount of increased insulin from the closed loop algorithm in response to the meal and/or the time since the meal to ensure that the risk of hypoglycemia is mitigated while still reducing hyperglycemia.

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: Disclosed herein are systems and methods for automated insulin delivery that aid in treatment when a user has eaten and has forgotten to deliver a meal bolus to counteract the carbohydrates consumed in the meal. The systems and methods disclosed herein can modify a limiter function that limits an amount by which a basal rate can be increased following a given glucose level reading in certain circumstances. For example, if the user's current or predicted future glucose level is high and the user's glucose level is increasing above a threshold rate, the limit can be increased from a standard limit. Such a glucose response may indicate that the user has eaten, but forgotten to instruct a meal bolus. By increasing the basal rate increase limit, the system can therefore react to and address the missed meal bolus.

Abstract: Disclosed herein are systems and methods for automated insulin delivery that reduce a risk of hypoglycemia from automatically delivering correction boluses. Rather than automatically delivering a correction bolus when a current or future predicted glucose level of a user is over a high glucose threshold, the system can review additional factors to determine whether an automatic correction bolus is appropriate. For example, the system can be prevented from delivering an automatic correction bolus if the user's glucose levels are falling at greater than a predetermined rate and/or if a current glucose level is greater than a future predicted glucose level even if the user's current or predicted future glucose levels is over the high threshold.
