  • Patent number: 10617825
    Abstract: A drug delivery device (1) is provided comprising a housing (2), a cartridge holder (3) which is adapted and arranged for receiving a cartridge (4) for holding a plurality of doses of a drug (5), wherein the cartridge holder (3) is removable from the housing (2) to enable an exchange of the cartridge (4), a piston rod (9) adapted and arranged to be moved from an initial position towards an end position for dispensing a dose of drug (5) from the device (1) and to be moved from the end position back towards the initial position to perform a reset operation of the device (1), and at least one resilient member (20, 25). The at least one resilient member (20, 25) is in direct mechanical contact with the piston rod (9) and the resilient member (20, 25) is adapted and arranged to prevent an unintentional movement of the piston rod (9) towards the initial position due to mechanical cooperation with the piston rod (9).

  • Patent number: 9370623
    Abstract: A drive assembly for a medication delivery device is provided, comprising a piston rod which is movable from a start position to an end position for medication delivery and resettable from the end position to the start position. The drive assembly further comprises a guide member, being in engagement with the piston rod, and an impeding element for impeding a movement of the guide member during a reset of the piston rod and thereby impeding the reset of the piston rod. Furthermore, a medication delivery device comprising the drive assembly is disclosed.

  • Patent number: 9272096
    Abstract: A drive assembly for a drug delivery device is disclosed. The drive assembly is connectable with a cartridge holder and comprises a housing, a piston rod, the piston rod being movable in a distal direction for drug delivery, and a guide nut, the guide nut being rotatable relative to the housing around an axis of the assembly and provided for guiding the piston rod. A locking means is provided which is enabled to take an engaged state in which the locking means is engaged with the guide nut in order to prevent rotation of the guide nut and to take a disengaged state in which the locking means is disengaged from the guide nut in order to allow rotation of the guide nut. Moreover, a coupling means is provided, the coupling means being rotatable relative to the housing around the axis of the assembly for interaction with the locking means in order to change between the engaged state and the disengaged state of the locking means.
