Abstract: The present disclosure relates to a drug delivery device, having a longitudinal axis and comprising a plunger movable along the longitudinal axis and a guide curve adapted to engage at least one part of the plunger so as to guide the plunger when the plunger is being released to move along the longitudinal axis.

Abstract: The present disclosure relates to an audible indicator for use with a drug delivery device comprising a resilient force member configured to reside in one of a relaxed state and a biased state. The audible indicator comprises a retainer adapted to maintain the resilient force member in the biased state. The resilient force member releases stored energy to impact a surface to generate an audible signal when the resilient force member changes from the biased state into the relaxed state.

Abstract: The present specification relates to a plunger configured to transmit a force from an energy source to a piston of a primary container, the plunger comprising a plunger rod configured to be subjected to the force from the energy source, the plunger rod having an inner surface forming a cavity, wherein a support element adapted to constrain the energy source within the cavity protrudes radially inwards from the inner surface into the cavity.

Abstract: A drug delivery device that includes a housing. The housing contains a syringe, and the syringe includes a container containing a liquid medicament. The container includes an aperture at a distal end and through which the liquid medicament can be dispensed. The syringe includes a stopper within the container. The stopper is moveable between a first longitudinal position and a second longitudinal position relative to the container, to cause dispensing of the liquid medicament through the aperture. The syringe includes at least one identifying means identifying the liquid medicament.

Abstract: The disclosure relates to a drug delivery device including: a housing configured to contain a drug container with a needle, a needle shroud that is telescopically connected to the housing, and a cap that is configured to be releasably connected to the housing before use of the device. At least one of the cap and the needle shroud is adapted to unreleasably lock the cap onto the housing after reapplying the cap onto the housing after the drug delivery device is used.
