    摘要: The autoinjector (1) includes: a housing (2) extending along a longitudinal axis A; a needle cover (5) coupled to and axially movable with respect to said housing (2) between a first extended position, a retracted position, and a second extended position in which the needle cover (5) moves back in the distal direction to shield an injection needle; a plunger rod (4) axially movable inside the housing (2) between a storage position and an injection end position; a retainer (8), movable with respect to the plunger rod (4) between a blocking position, in which the retainer (8) blocks the plunger rod (4) in the storage position, and a release position, in which the retainer (8) is moved away from the plunger rod (4) to allow axial displacement of the plunger rod (4) from the storage to the injection end position; a locker (9), movable with respect to the retainer (8) between a locking position, in which the locker (9) locks the retainer (8) in the blocking position, and a release position, in which the locker (9) allows movement of the retainer (8) to the release position, movement of the locker (9) from the locking position to the release position being caused by the needle cover (5) moving from the first extended position to the retracted position; and a controller (7), movable with respect to the housing (2), between a storage position which the controller (7) prevents activation of the autoinjector (1) and an activated position allowing for activation of the autoinjector (1), said controller (7) including a grasping member (73) configured for allowing a user to move the controller (7) from the storage position to the activated position. The locker (9) is connected to the controller (7) such that movement of the controller (7) with respect to the housing (2) between the storage and activated position entails movement of the locker (9) with respect to the housing (2) between a corresponding storage and an activated position. The locker (9) includes a blocking member (96) configured for abutting against a stop (281) of the housing (2) as long as the locker (9) is in the storage position, and the blocking member (96) of the locker (9) is moved away from said stop (281) of the housing (2) when the locker (9) is moved to the activated position.

    摘要: A medicament delivery device configured to provide a variable single dose of medicament is disclosed. The medicament delivery device includes a main body and a syringe arranged in the main body, where the syringe comprises a medicament. The medicament delivery device further includes a delivery member shield unit slidably arranged in the main body and a removable cap releasably coupled to the delivery member shield unit. The medicament delivery device also includes a dose knob configured to rotate with respect to the main body for setting a dose of the medicament. Prior to a dose of the medicament being set, the delivery member shield unit and the removable cap are axially locked with respect to the main body. Further, after a dose of the medicament is set, the delivery member shield unit and the removable cap are axially moveable with respect to the main body.

    摘要: The present disclosure relates to a drug delivery device having a case adapted to retain a medicament container, a plunger disposed within the case and slidable from a proximal position into a distal position for delivering a medicament from the medicament container, and at least one feedback mechanism that is in operative connection with the plunger. The feedback mechanism includes a collar, a needle shroud, and a control spring biasing the needle shroud in a distal direction relative to the collar. The collar is operatively coupled to the case in an axial direction and prevented from axially decoupling from the case by the plunger when in the proximal position. The plunger, during movement from the proximal position towards the distal position, allows axial decoupling of the collar from the case driven by the control spring until the collar's movement is halted, which creates an audible and/or tactile feedback.

    摘要: In a piston for a syringe, in particular an injection syringe, which has a hollow body receiving the piston, comprising a piston head for fluid-tight delimitation of a liquid chamber of the syringe, and a piston rod firmly connected to the piston head and having an actuation portion on which the piston can be actuated for insertion into the hollow body, wherein the piston rod is formed by a plurality of axial webs which extend in the longitudinal direction and which have a radial axial extent outwards from the longitudinal axis and open radially into a common intersection portion receiving the longitudinal axis, wherein at least one free excitation edge protruding radially beyond the radial axial extent is provided on the piston rod, which excitation edge can be brought into engagement with an oscillation exciter of the hollow body upon insertion of the piston, in such a way that an acoustic signal is emitted, provision is made that an oscillation arm body arranged between two axial webs couples the excitation edge to the intersection portion in such a way that, in the event of oscillatory excitation in the axial direction, the oscillation arm body has a radial oscillation arm length, between the excitation edge and the intersection portion, of at least 40% of the radial axial extent.
