  • 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.

  • Patent number: 10940266
    Abstract: A control unit for an electronically controlled pump unit controls the pump unit to infuse insulin into a diabetic's body in a substantially continuous way according to a preset infusion schedule as a function of time. The control unit includes an intervention unit that continuously evaluates a blood-glucose indicative input for detecting an actual or expected hypoglycaemia and executes, in response to an actual or expected hypoglycaemia, a temporary hypoglycaemia intervention. The intervention includes, for an intervention time interval, overriding the preset infusion schedule by temporarily suspending insulin infusion or temporarily reducing insulin infusion below the preset infusion schedule. The intervention unit adapts its way of operation with respect to executing the hypoglycaemia intervention in accordance with a control signal that is separate from the blood-glucose indicative input. The control unit automatically generates the control signal as a function of time and/or based on sensor input.
