Abstract: The disclosure relates to a drug delivery device including a plunger disposed within a case and an audible indicator that comprises a resilient element. The plunger is slidable from a proximal position to a distal position within the case and the resilient element is in a first configuration when the plunger is in the proximal position, such that the resilient element is deflected radially outwards to a second configuration during movement of the plunger from the proximal position towards the distal position. The resilient element moves from the second configuration towards the first configuration when the plunger moves towards or reaches the distal position, thereby generating an audible and tactile signal.

Abstract: A syringe carrier includes a housing adapted to receive a syringe having a needle encapsulated by a removable protective needle sheath, and two or more flexible arms protruding inwards in a relaxed state and adapted to couple with the syringe in a mounted position. The flexible arms are adapted to deflect radially outwards in a pre-assembled position of the syringe in the syringe carrier. In the mounted position the flexible arms are allowed to return into the relaxed state due, in part, to an axial force operating on the syringe carrier. The disclosure further relates to an autoinjector and a method of assembling the autoinjector.

In a biased state, the resilient force member is biased and stores energy In a relaxed state, the resilient force member is relaxed. The resilient force member releases the stored energy when transitioning from the biased state into the relaxed state, thereby generating an audible signal.

Abstract: The disclosure relates to an audible indicator in combination with a drug delivery device having a resilient force member capable of resting in either of two states. In a biased state, the resilient force member is biased and stores energy and in a relaxed state, the resilient force member is relaxed. The resilient force member releases the stored energy when changing from the biased state into the relaxed state, thereby generating an audible signal, wherein the resilient force member is supported by a retaining element in the biased state in order to prevent transition into the relaxed state.

Abstract: A drug delivery device comprising a case adapted to hold 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, an audible indicator that is arranged within a case pocket lateral to the plunger and that is in operative connection with the plunger, the audible indicator comprises at least one indicator spring and at least one locking element. The indicator spring is biased by the locking element, and the indicator spring relaxes due to a release of the locking element by a movement of the plunger.

Abstract: Described is an autoinjector comprising a case, a chassis slidably arranged in the case, a syringe carrier operably coupled to the chassis, an outer plunger selectively engaged to the chassis, an inner plunger selectively engaged to the outer plunger, and a drive spring applying a biasing force to the outer plunger. The biasing force is applied to the inner plunger when the inner plunger is engaged to the outer plunger. Rotation of the chassis causes the inner plunger to rotate relative to the outer plunger and disengage the outer plunger to remove the biasing force from the drive spring on the inner plunger. When the inner plunger disengages the outer plunger, the biasing force of the drive spring pushes the chassis to retract the syringe carrier relative to the case.
