Abstract: Some embodiments of an infusion pump system can be used to determine a user's total insulin load (TIL) that provides an accurate indication of the insulin previously delivered to the user's body which has not yet acted. In particular embodiments, the TIL can account for both the bolus deliveries and the basal deliveries that have occurred over a period of time. Such information may be useful, for example, when the infusion pump is operated in conjunction with a continuous glucose monitoring device.

Abstract: Examples of fluid delivery drive system and/or pump system that creates a vacuum in a fluid line for drawing and expelling fluid are provided. The vacuum may be created by separating two components that are positioned within the sealed fluid line. Once the two components are separated and the fluid is contained within the volume created between the separated components, the two components may be shuttled within the sealed volume. The movement of the two components can seal off an inlet to the fluid line and then open a pathway to an outlet from the fluid line while ensuring the created volume between the two components is maintained constant. The two components can then be moved back together to expel the fluid from the created volume through the outlet for delivery, for example, to a patient. Other examples are disclosed and described.

Abstract: Methods, devices, and systems of delivering infusion fluid (e.g., medication such as insulin) can detect, at multiple times during a dispensation period of time, a pressure level of the infusion fluid in an infusion fluid pathway, either directly or indirectly. Based on the detected pressure levels, one or more actual dispensation times that are after an intended dispensation time can be determined. In some cases, methods, devices, and systems provided herein can use variable occlusion alarm thresholds, which can depend on variables such as an age of an infusion set and/or a current analyte level. In some cases, methods, devices, and systems provided herein can automate medication delivery and use the actual dispensation times in a control algorithm determining medication deliveries.

Abstract: Systems, methods, and devices provide alarms and alerts in an on-body networked diabetes management system. Methods may include receiving glucose sensor data from a continuous glucose monitor and determining a dosage of insulin delivery based at least in part on the glucose sensor data. The method may include detecting an alarm or alert condition, and sending a wireless communication regarding the alarm or alert condition to a remote user-interface device. The method may include triggering an audible, visual, or haptic alarm or alert on the insulin delivery device unless an acknowledgement of the alarm or alert condition is received within a predetermined period of time.

Abstract: Some embodiments of an infusion pump system may be configured to wirelessly communicate with other devices using near field communication (NFC). In particular embodiments, by incorporating near field communication capabilities into the infusion pump system, user communications with the infusion pump system can be enhanced and simplified.

Abstract: The embodiments described herein may relate to methods and systems for adjusting insulin delivery.

Abstract: A method may include displaying to a user an interface at which the user inputs a fear of hypoglycemia index (FHI), the FHI corresponding to an acceptable probability of a blood glucose level being below a threshold blood glucose level. The method may also include receiving blood glucose data for a person with diabetes (PWD). The method may additionally include calculating a probability of the PWD having a blood glucose level below the threshold blood glucose level based on the variability of the received blood glucose data. The method may also include setting one or more target blood glucose levels to align the probability of the PWD having a blood glucose level below the threshold blood glucose level with the acceptable probability associated with the user input FHI. The method may additionally include delivering insulin, using the insulin delivery device, based on the target blood glucose level.

Abstract: Disclosed are a system, methods and computer-readable medium products that provide safety constraints for an insulin-delivery management program. Various examples provide safety constraints for a control algorithm-based drug delivery system that provides automatic delivery of a drug based on sensor input. Glucose measurement values may be received at regular time intervals from a sensor. A processor may predict future glucose values based on prior glucose measurement values. The safety constraints assist in safe operation of the drug delivery system during various operational scenarios. In some examples, predicted future glucose values may be used to implement safety constraints that mitigate under-delivery or over-delivery of the drug while not overly burdening the user of the drug delivery system and without sacrificing performance of the drug delivery system. Other safety constraints are also disclosed.

Abstract: Systems and methods for monitoring an operational state and/or a fill status of a drug container of a drug delivery device are provided. The drug container can hold a liquid drug. A plunger can be positioned within the drug container. A drive system can advance the plunger to expel the liquid drug from the container. A monitoring system can detect a movement and/or a position of the plunger and/or any component coupled to the plunger. The detection can enable determination of an amount of liquid drug that has been expelled and/or an amount of liquid drug remaining in the drug container. Dosing rates, flow rates, and dosage completion can also be determined.

Abstract: An improved basal insulin management system and an improved user interface for use therewith are provided. User interfaces are provided that dynamically display basal rate information and corresponding time segment information for a basal insulin program in a graphical format. The graphical presentation of the basal insulin program as it is being built by a user and the graphical presentation of a completed basal insulin program provides insulin management information to the user in a more intuitive and useful format. User interfaces further enable a user to make temporary adjustments to a predefined basal insulin program with the adjustments presented graphically to improve the user's understanding of the changes. As a result of being provided with the user interfaces described herein, users are less likely to make mistakes and are more likely to adjust basal rates more frequently, thereby contributing to better blood glucose control and improved health outcomes.
