  • Patent number: 11324889
    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.

  • Patent number: 11278671
    Abstract: An infusion pump is configured to provide one or more context cues to a user while the user programs the infusion pump to deliver an infusion therapy. In some embodiments, the infusion pump includes a display configured to display a keypad and to receive input from a user, a processor in communication with the display, and a memory in communication with the processor. The memory stores instructions that cause a keypad sequence monitor to receive context parameters, the context parameters corresponding to a drug selection, a drug concentration selection, or a clinical care area in which the drug is to be infused. The keypad sequence monitor accesses a drug library using the context parameter to determine a valid parameter range corresponding to a range of values between lower and upper soft limit values stored in the drug library.

  • Patent number: 11229752
    Abstract: A needle hub assembly for coupling to a pen needle delivery device includes an outer cover having a first well receiving the needle hub and inner shield covering a cannula of the needle hub. A second well is spaced from the first well and receives the inner shield. In use, the pen delivery device is coupled to the connecting end of the needle hub to withdraw the needle hub and inner shield from the first well. The inner shield is inserted into the second well where the inner shield is gripped so that the inner shield can be separated from the needle hub without the user handling the outer cover or the inner shield. After use, the needle hub is inserted into the first well and the pen needle delivery device is separated from the needle hub. The needle hub is retained within the first well where the outer cover containing the used needle hub and inner shield can be discarded as a single unit.
