  • Publication number: 20230021831
    Abstract: An autoinjector includes a housing, a product container, a torsion spring, a drive element, and a propulsion element. In order to discharge liquid out of the product container, the torsion spring rotates the drive element, and the rotating drive element produces a propulsive movement of the propulsion element and of a piston in the product container. A rotation sensor is configured for an alternating continuous detection of at least two rotational positions per revolution of the drive element during the discharge process, and a processor unit is configured for determining the axial position of the piston in the product container from the detected rotational positions.

  • Publication number: 20220233777
    Abstract: A housing for a drug delivery device for administrating a liquid drug from a cartridge includes a recess for accommodating a proximal portion of the cartridge and a deformable member arranged inside the recess. The deformable member includes a proximal end attached to the housing and a distal end movable within the recess. The deformable member is deformable from a non-deformed state to a deformed state by a displacement of the distal end. In the deformed state the deformable member is adapted to limit a movement of a cartridge in the longitudinal direction relative to the housing. The deformable member further includes an arch, and in the deformed state the arch is deformed both elastically and plastically.

  • Patent number: 11253653
    Abstract: A segmented piston rod for an injection device includes multiple segments joined together via a hinge located on one side of each segment. The piston rod can be bent in one direction by articulating subsequent hinges while an axial force can be transmitted by the segmented piston rod to the stopper when the subsequent hinges are closed and the segments abut each other opposite to the one side of the hinge. The segmented piston rod is secured against rotation relative to the housing around the longitudinal axis of the segmented piston rod. The segmented piston rod has a last element which abuts the stopper in the reservoir and a first segment which is opposite to the last segment. The first segment is includes an internal thread matching an external thread of a drive sleeve and rotation of the drive sleeve advances the piston rod towards the stopper of the reservoir.

  • Publication number: 20210154407
    Abstract: An autoinjector for dispensing a liquid product includes a housing; a product container arranged in the housing, particularly, a syringe comprising a displaceable piston; a drive member; a first spring which acts on the drive member and the piston to dispense the product from the container; signal element releasably axially coupled with the drive member so that the signal element is transported in the dispensing direction as said drive member is displaced; and a second spring, which exerts a spring force on the signal element against the dispensing direction and is tensioned as the signal element is transported in the dispensing direction. When the signal element is released or detached from the axial coupling, the second spring causes the signal element to accelerate opposite the dispensing direction and strike against a signal stop and generate an acoustic and/or tactile signal.

  • Publication number: 20210146059
    Abstract: Dosing device for an administration device with a limiting mechanism containing: a dosing sleeve with a first stop and a stop wheel with a second stop means adapted to continually and proportionally follow a movement of the dosing sleeve during dosing movements. During an ejection movement, there is no relative movement between dosing sleeve and stop wheel. The first stop and the second stop each describe a path curve by their movements such that the two path curves intersect in one point and the stops contact one another and tilt the stop wheel, thereby blocking the dosing movement of the dosing sleeve. The stop wheel comprises first and third sloped surfaces that may form first and second gear guidances with a clutch thereby returning the stop wheel to a non-tilted position during up or down dosing movements when the stops do not contact another.

  • Publication number: 20210138151
    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. A control element, linearly guided by the housing, moves transversely to the needle axis from a starting position, via a needle insertion release position, to a needle retraction release position. 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.
