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.

Systems and methods for automated insulin delivery for diabetes therapy

Disclosed herein are systems and methods for safely switching between medicament delivery control algorithms for control of an ambulatory infusion pump or other medical device. Infusion pumps and/or remote control devices may be capable of operating different algorithms for delivery of medicament and provided herein are mechanisms for safely transitioning between algorithms.

System and method for switching between medicament delivery control algorithms

Embodiments are directed to portable infusion devices, systems, and methods of using the same for dispensing materials. In some cases, the devices, systems and methods may be used for infusing a material such as medicament, e.g., insulin, into a body in need thereof.

Disclosed herein are apparatuses and methods that account for exercise in closed loop insulin delivery systems. Rather than increasing a target insulin on board (IOB) as glucose levels rise, which would increase insulin delivery to address the raised glucose levels, when a user indicates that the user will be exercising raised glucose levels are addressed by reducing the target IOB within the closed loop algorithm. By reducing the target IOB, the algorithm responds less aggressively to pre-exercise food, and does not build up the IOB that can cause dangerously low glucose levels once the exercise also begins lowering glucose levels.

System and method for incorporating exercise into closed-loop diabetes therapy

Infusion pump systems and methods

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.

Methods of incorporating CGM data into diabetes therapy

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.

Transitioning to other modes in automated insulin delivery

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.

Systems and methods for automated insulin delivery response to meal announcements

A portable medical device is operated in an active mode in which the device receives a user input at an input interface and provides the received user input to a processor of the device. The active mode is terminated and the device is operated in a safe mode, in which the received user input is not provided to the processor and/or one or more device function is disabled, in response to determining that the received user input was received in an out of bounds region of the input interface. The safe mode is terminated in response to receiving a predetermined user input comprising an activation input.

Preventing inadvertent changes in ambulatory medical devices

A file system that balances the loading of filers and the capacity of drives that are associated with the filers is described. The file system includes a first disk drive that includes a first unused capacity and a second disk drive that includes a second unused capacity, wherein the second unused capacity is smaller than the first unused capacity. The file system further includes a first filer that is configured to fill requests from clients through access to at least the first disk drive. The file system further includes a second filer that is configured to fill requests from clients through access to at least the second disk drive. The second filer is configured to select an infrequently accessed file from the second disk drive and to push the infrequently accessed files to the first disk drive, thereby improving a balance of unused capacity between the first and second disk drives without substantially affecting a loading for each of the first and second filers.
