Abstract: The provided examples of systems, devices and techniques improve systems and methods for keeping users of automatic drug delivery systems engaged and assisting with the optimal use of the drug delivery system. The automatic drug delivery system may include a drug delivery device and a controller. Through the use of an attrition prevention engine in a cloud-based services system that cooperates with an attrition prevention application executing on the controller of the drug delivery device, notifications that include instructions for adjusting operation of the drug delivery device as well as offer assistance to the patient to optimize performance of the drug delivery system for the patient may be provided. Optimizing the performance of the drug delivery system has been shown to prevent attrition of patients from using the drug delivery system.

Abstract: Disclosed are systems, devices, methods and computer-readable medium products that implement a vibrational event by a wearable drug delivery device. The wearable drug delivery device includes vibrational actuators that vibrate in response to a control signal from a controller. The controller may be controlled by an external device that issues command signals with instructions related to settings of the vibrational event. The vibrational event settings may be modified based on signals received from sensors on the wearable drug delivery device. The vibrational events may be implemented as an element of a site maintenance plan that alleviates the degeneration of tissue at one or more body attachment sites of the wearable drug delivery device.

Abstract: Disclosed are a drug delivery system, a drug delivery device, a controller and a number of techniques to personalize the delivery of a bolus dosage. In an example, a drug delivery system may include a processor and a memory. The memory may be operable to store instructions that, when executed by the processor, cause the processor to receive a request to deliver a bolus dosage, retrieve a history of glucose measurement values, extract features from the history of glucose measurement values, assign a value to extracted features and calculate a personalized factor, and based on the personalized factor or factors, modify a calculation for an amount of a medicament to deliver. Additionally or alternatively, the personalized factor may be used to modify parameter settings of a medicament delivery algorithm. The described systems may track a user's personalized factor over a period of time.

Abstract: Safety and accuracy measures may be provided in a medicament delivery device. The medicament delivery device may be able to identify the inadvertent delivery of duplicate medicament boluses by a user. The exemplary embodiments may set limits for maximum allowable medicament bolus doses and maximum cumulative bolus doses over an interval. The exemplary embodiments may provide automatic meal detection and may use detection of meals in determining whether a user-requested medicament bolus dose should be adjusted or rejected. The exemplary embodiments may facilitate delivery of partial boluses and the delivery of remainders of the boluses contingent on acceptable glucose level trends of the user. The exemplary embodiments may resolve potential conflicts among multiple medicament delivery devices via a broker or by providing a single actor, such as a medicament delivery controller, that has sole control of dosing and delivery of medicament boluses.
