Abstract: A drug delivery device including a reservoir configured to contain a fluid to be delivered by advancing a piston in the reservoir at an advancement speed defining a delivery rate for the medicament. The device further includes an electric motor configured to drive the delivery mechanism by rotation to advance the piston at the advancement speed. The device further includes a control unit that controls a rotational speed and an on state/off state of the electric motor. The control unit determines rotational speed of the electric motor based on a back-electromagnetic force signal provided from the electric motor while operating in a monitoring mode. The control unit controls the rotational speed of the electric motor such that a back-emf signal can be detected in the monitoring mode. The control unit modulates the on state/off state of the electric motor to adjust the delivery rate of the medicament.

Abstract: A needle insertion and retraction mechanism for a medication delivery device includes a housing and a needle carrier holding a needle guided by the housing and moved along a needle axis. A first spring member is adapted to move the carrier in an insertion direction. A second spring member is adapted to retract the carrier in a retraction direction, opposite the insertion direction.

When the control element is in its starting position, the control element is coupled to the carrier to prevent the carrier from moving in the insertion direction. When the control element is in the release position, the control element is decoupled from the carrier and the first spring member drives the carrier in the needle insertion direction.

Abstract: Monitoring an injection process executed by a variable dose injection device with feedback means for generating a number of feedback events proportionate to the dose to be determined is disclosed. A dialed or injected dose is determined by measuring a first signal of the process comprising a first signal peak related to a feedback event; detecting the first signal peak in the first signal; selecting an evaluation interval comprising the detected peak and adapted to an expected peak duration; deriving, from the first signal limited to the evaluation interval, a feature or characterizing parameter of the feedback event; identifying, from the derived feature, the feedback event as one of a dial up, dial down, or expel feedback event, and counting identified feedback events to determine the dialed or the ejected dose. The two-stage approach with serially executed peak detection and peak identification allows to optimize data storage and processing power.
