  • Publication number: 20210113160
    Abstract: A user may be alerted by one or more user devices when the blood glucose level of the user is outside of a predefined threshold. When the predefined threshold for the blood glucose level of the user is reached, the user be in a state of elevated mental confusion and may be unable to realize the extreme state or take immediate action self-treat the diabetic condition. In response, the user may be provided with a self-treat test that includes pass/fail criteria to test the ability of the user to self-treat themselves. If the user passes the self-treat test, the user may be assumed to be able to self-treat the diabetic condition.

  • Patent number: 10967120
    Abstract: A portable liquid drug delivery device has a reservoir part and a driving part, and the driving part has a drive that produces a torque. The reservoir part has a reservoir that retains liquid drug and an outlet port is in fluid communication with the reservoir. An engagement member has an inner thread that engages the thread of a piston rod in an engaged position and is disengaged from the thread of the piston rod in a disengaged position. The engagement member is prestressed in the disengaged position to thereby bias the engagement member toward the engaged position. The engagement member only converts the torque of the drive into a linear movement of the piston rod when the engagement member is in the engaged position. The piston is configured, upon the linear movement of the piston rod, to deliver the liquid drug to the outlet port.
