  • Patent number: 10213554
    Abstract: A medial assembly comprises a logging first unit adapted to be mounted on a drug delivery device second unit from a fully un-mounted to a fully mounted position along a path. The first unit comprises a switch operatable between an off- and an on-state when the first unit is mounted on the second unit, the switch being in the on-state when the first unit is mounted within a first distance from the fully mounted position, and in the off-state when the first unit is mounted outside the first distance from the fully mounted position, and a snap lock operatable from an initial state through an expanded state to a snap-in state when the first unit is mounted on the second unit, the snap lock being in the snap-in state when the first unit is mounted within a second distance from the fully mounted position, the second distance being shorter than the first distance. By this arrangement it is ensured that the switch will be in the on-state before the snap lock is in the snap-in state.

  • Patent number: 10195358
    Abstract: The piston rod arrangement is in an assembled state before use and comprises a piston rod, a bung, which is intended to be driven by the piston rod, a body member, and a drive member. The piston rod is threadedly engaged with the body member, and the drive member is threadedly engaged with the piston rod and movable relative to the body member. A mechanism is provided defining unit steps of movement of the drive member and corresponding unit steps of movement of the piston rod. The piston rod is arranged in contact with the bung or at a distance from the bung that is less than a distance of one corresponding unit step of movement. When the piston rod, the bung and the drive member are assembled in the body member, the piston rod is advanced with respect to the body member towards the bung, until the piston rod is stopped by the bung. The drive member is rotated until the piston rod begins to advance again and the drive member is then stopped, and the piston rod is fixed at or near the position obtained.

  • Patent number: 10179212
    Abstract: An injection device for expelling a dose of drug from a held cartridge (600) is described. A needle shield (350, 380) is axially movable relative to a base (200, 220, 230) between a proximal collapsed position and a distal extended position. A needle shield lock comprises a deflectable lock element (392) operable to prevent the needle shield (350, 380) from being moved towards the proximal collapsed position. A lock activator (402) associated with a plunger (310, 400) exerts an activation force on the deflectable lock element when the plunger assumes a final position. A biasing means (403) is arranged to act between the lock activator (402) and the deflectable lock element (392), the biasing means (403) being configured to resiliency transfer the activation force from the lock activator (402) to the deflectable lock element (392) to enable the needle shield (350, 380) to become locked in the distal extended position but only when the plunger (310, 400) assumes the final position.
