Abstract: Disclosed are exemplary drug delivery systems that include controllers, drug delivery devices, and the like. The disclosed drug delivery system and controllers may include a processor, a user interface, a memory, and communication circuitry. An automated drug delivery algorithm is operable to receive a number of different inputs related to a user's glucose and/or ketone levels. The automated drug delivery algorithm(s) of the described drug delivery systems and controllers are operable to adjust to when a user partakes in fasting for a period of time that lasts a day or multiple days. The period of time may be a fasting event, such as a religious holiday or diet regimen. For example, the disclosed automated drug delivery algorithm(s) are operable to receive an indication of initiation of a fasting mode; and modify a drug delivery schedule based on the period of fasting or while in fasting mode.

Abstract: The exemplary embodiments may detect compression of a biological sensor and/or biological tissue of the user and may prompt or take corrective action to address the compression. A compression sensor may be provided to sense compression of the biological sensor and/or biological tissue of the user. Sensor data from the compression sensor may be processed to detect the compression. The detection of the compression may trigger corrective action. The corrective action may include an alert to alert the user to suggest a change in position or body orientation so as to alleviate the compression. The corrective action may include adjusting the biological sensor data to compensate for the compression or may include adjusting the quantity or rate of medicament delivered to a user to compensate for the compression. In some exemplary embodiments a data logger is provided to work with the biological sensor. The data logger may automatically log compression sensor data and biological sensor data.

Abstract: Disclosed are an apparatus, system, processes, and techniques for adapting drug delivery and monitoring a user's safety when the user is experiencing a sick day. A processor may be operable to provide a graphical user interface that presents a sickness mode prompt for a user to indicate that the user or another person with diabetes is sick. The graphical user interface may present symptoms from which a user may select. Based on the selection of symptoms, glucose measurement values, and/or ketone measurement values, a response to the user's indication of sickness may be provided.

Abstract: Disclosed are a system, techniques and processes for monitoring and modifying a drug treatment regimen when a user partakes in a ketogenic diet. The disclosed system obtains ketone level measurements of a user and indicates a user's adherence to the ketogenic diet as well as modifying a user's total daily dosage of a drug based on the user's following the ketogenic diet.

Abstract: Disclosed herein are systems and methods for providing safeguards, in an automatic drug delivery system, to prevent or compensate for insufficient delivery of bolus doses of a liquid drug. The safeguards include, for example, features built into the medication delivery algorithm to allow the medication delivery algorithm to ensure that proper bolus doses are delivered, either manually by the user or automatically by the drug delivery system. In addition, various methods are described for providing the medication delivery algorithm with a means for determining when a meal has been ingested and, in some embodiments, for providing an automatic bolus dose of the liquid drug in response to the determination.

Abstract: The disclosed embodiments are directed to methods for dynamically adjusting the total daily insulin requirements of a user during pregnancy, based on the gestational week. An initial estimate of the adjusted total daily insulin requirement may be calculated as a multiple of the pre-pregnancy total daily insulin requirement, based on an average scale factor from a population of pregnant women suffering from Type I diabetes mellitus. An automatic drug delivery device may adjust the initial estimate of the total daily insulin requirement based on blood glucose level readings from a continuous glucose monitor during the course of the pregnancy.
