    Abstract: Disclosed are techniques, a system and devices that enable the setting of an upper boundary constraint that may be a multiple of a total daily dosage setting for a liquid drug being administered to a user to control a condition, such as type 1 or type 2 diabetes mellitus. An automatic drug delivery algorithm may be configured to obtain a glucose control metric. A controller executing the automatic drug delivery algorithm may ascertain, based on the glucose control metric, an upper boundary constraint for the liquid drug that limits an amount of a dose of the liquid drug that may be delivered by the automatic drug delivery system or components thereof.

    Abstract: Exemplary embodiments may address the problem of missing blood glucose concentration readings from a glucose monitor that transmits blood glucose concentration readings over a wireless connection due to problems with the wireless connection. In the exemplary embodiments, an automated insulin delivery (AID) device uses an estimate in place of a missing blood glucose concentration reading in determining a predicted future blood glucose concentration reading for a user. Thus, the AID device is able to operate normally in generating insulin delivery settings despite not receiving a current blood glucose concentration reading for a current cycle. There is no need to suspend delivery of insulin to the user due to the missing blood glucose concentration reading.

    Abstract: Disclosed are a device, system, methods and computer-readable medium products that provide techniques to implement functionality to receive information related to a meal and delivery of a meal bolus. The received information may be stored and utilized in the generation of insulin delivery profiles. An estimate a mealtime insulin need based on the generated insulin delivery profiles may be generated. A dose of insulin may be determined that satisfies an estimated mealtime insulin need based on the generated insulin delivery profiles. The determined dose of insulin may be output at a time corresponding to a mealtime.

    Abstract: Disclosed are a device, system, methods and computer-readable medium products that provide techniques to implement functionality to receive blood glucose measurements over a period of time. An average of missing blood glucose measurement values may be maintained over a predetermined time period. A count of a number of missing blood glucose measurement values over a period of time may be established. A controller may calculate a divergence of the number of missing blood glucose measurement values over the period of time from the average of missing blood glucose measurements over the predetermined time period. Based on a value of the divergence, a determination that a safety constraint for delivery of insulin is to be reduced. The safety constraint may be reduced by a predetermined percentage. An instruction to deliver an insulin dosage may be generated according to the reduced safety constraint may be forwarded to a wearable drug delivery device.

    Abstract: Disclosed are a system, methods and computer-readable medium products that provide bolus dosage calculations by a control algorithm-based drug delivery system that provides automatic delivery of a drug, such as insulin or the like, based on sensor input. Blood glucose measurement values may be received at regular time intervals from a sensor. Using the blood glucose measurements, the control algorithm may perform various calculations and determinations to provide an appropriate bolus dosage. The appropriate bolus dosage may be used to respond to a trend in a trajectory of blood glucose measurements. In addition, a bolus dosage may also be determined by the disclosed device, system, method and/or computer-readable medium product in response to an indication that a user consumed a meal.

    Abstract: Systems and methods for automatically delivering medication to a user. An automated drug delivery system may include a sensor and a wearable automated drug delivery device. The wearable automated drug delivery device may be configured to couple to the skin of a user and may include a controller and a pump. The pump may be configured to output the medication. The controller may be within the wearable automated drug delivery device. The sensor may be coupled to the user and may be configured to collect information regarding the user. The controller of the wearable automated drug delivery device may use the collected information to locally determine an amount of medication to be output from the wearable automated drug delivery device and cause delivery of the amount of medication.

    Abstract: Disclosed are techniques, devices and systems that provide adjustments to parameter settings of an insulin delivery algorithm based on inputs from a number of generic sensor devices. A majority of the generic sensor devices provide sensor readings that are unused as inputs to a drug deliver algorithm. The generic sensor devices may be operable to detect characteristics, such as changes in a state of a user. A processor may evaluate a sensor reading provided by a particular sensor with respect to a sensor baseline reading for the particular sensor. Using the result of the evaluation, the processor may calculate an adjustment to a parameter setting or settings of a medication delivery algorithm. A dosage of medication may be modified based on the adjustment of the parameter setting or settings.
