Abstract: A method of operating a system having a fluid pump mechanism and a related controller involves: operating the system in a first mode to automatically deliver the medication in accordance with a therapy control algorithm; and receiving stress-identifying data generated at least in part from gesture data for the user. The gesture data is provided by a gesture-based physical behavior detection system. The method determines, from the stress-identifying data, that the user is under stress while the medication delivery system is operating in the first mode. In response to detecting stress, the system is operated in a second mode to automatically deliver the medication to the user in accordance with a stress-correlated therapy control algorithm. The second mode compensates for user stress as determined from the stress-identifying data.

Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device capable of delivering fluid to a patient involves predicting, by a control system associated with the infusion device, a future occurrence of an event based at least in part on historical data associated with the patient, and prior to the future occurrence of the event, automatically adjusting a control parameter for operating the infusion device based at least in part on the event and automatically operating an actuation arrangement of the infusion device to deliver the fluid to the patient based at least in part on a current measurement of the physiological condition and the adjusted control parameter.

Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device involves obtaining one or more measurement values of a physiological condition in the body of a user during an initial monitoring period and determining a fasting reference value for a metric based on the one or more measurement values. After the initial monitoring period, the method continues by obtaining an updated measurement value during a fasting period, determining a current value for the metric based at least in part on the updated measurement value, and generating a notification in response to a deviation between the current value and the fasting reference value exceeding a threshold indicative of insertion site loss or other loss of effectiveness.

Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of providing site rotation feedback pertaining to a sensing arrangement providing sensed measurements of a physiological condition in a body of a user involves obtaining one or more reference measurements of the physiological condition in the body of the user, determining a lag associated with the sensing arrangement based on a relationship between the one or more reference measurements and one or more of the sensed measurements, identifying a current site location on the body of the user associated with the sensing arrangement from among a plurality of site locations based on the lag, determining one or more performance metrics associated with the current site location, and providing sensor site feedback in a manner that is influenced by the one or more performance metrics.

Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver fluid to a body of a user involves obtaining measurement values for a physiological condition influenced by the fluid, autonomously operating the infusion device to deliver the fluid based at least in part on the measurement values, and detecting a nonactionable condition based on the measurement values. In response to detecting the nonactionable condition, delivery of the fluid is limited while maintaining autonomous operation of the infusion device. In one exemplary embodiment, the nonactionable condition is a rescue condition indicative of the user having consumed fast-acting carbohydrates, and thus insulin delivery may be automatically limited in response to detecting the rescue carbohydrate consumption.

Abstract: A controller for an insulin infusion device includes at least one processor device and at least one memory element that cooperate to provide a processor-implemented closed-loop start-up module. The start-up module is operated to initiate a closed-loop mode of the infusion device and to obtain a most recent sensor glucose value for the user. The start-up module also calculates a difference between the most recent sensor glucose value and a target glucose setpoint value. When the difference is less than or equal to a threshold value, the closed-loop insulin infusion rate is adjusted over time, based on a fixed final target glucose value that is derived from the target glucose setpoint value. When the difference is greater than the threshold, the infusion rate is adjusted over time, based on a dynamic final target glucose value that decreases over time toward the target glucose setpoint value.

Abstract: Processor-implemented methods of controlling an insulin infusion device for a user are provided here. A first method obtains and analyzes calibration factors (and corresponding timestamp data) for a continuous glucose sensor, and regulates entry into a closed-loop operating mode of the infusion device based on the calibration factors and timestamp data. A second method obtains a most recent sensor glucose value and a target glucose setpoint value for the user at the outset of the closed-loop mode. The second method adjusts the closed-loop insulin infusion rate over time, in response to the sensor glucose value and the setpoint value. A third method calculates an upper insulin limit that applies to the insulin infusion rate during the closed-loop mode. The insulin limit is calculated based on a fasting blood glucose value of the user, a total daily insulin value of the user, and fasting insulin delivery data for the user.
