Abstract: Injection systems for drug delivery are disclosed. A system may include a container filled or fillable with a drug, a stopper movably disposed in the container, a plunger, an energy source outputting a force, a mechanical linkage operable to transmit the force output by the energy source to the plunger to cause the plunger to act on the stopper to expel the drug from the container, and a trigger member. The system may have pre-injection state where the trigger member inhibits actuation of the mechanical linkage, an injection state where the trigger member permits actuation of the mechanical linkage, and a post-injection state where the plunger is stationarily positioned in an end-of-dose position. The system may be designed to limit the number of components included in various force transmission loops present in the pre-injection, injection, and/or post-injection states.

Abstract: A drug delivery device includes a housing defining a shell having a proximal end and a distal end and a longitudinal axis extending between the proximal end and the distal end, a needle assembly at least partially disposed within the housing at the proximal end, a drive assembly at least partially disposed within the housing and operably coupled to the needle assembly, and an audible indicator operably coupled to the drive assembly. The needle assembly includes a syringe containing a medicament and a needle or a cannula. The drive assembly is movable between an initial position and a second position that results in the medicament being expelled from the syringe. Upon the drive assembly being positioned in the second position, the audible indicator engages the drive assembly to generate an audible sound indicating the medicament has been expelled from the syringe.

Abstract: The present invention relates to a pharmaceutical adaptor system. The pharmaceutical adaptor system comprises a syringe assembly having an axial extension and comprising a first end part and a second end part, the first end part having a male tubular projection, the syringe assembly comprising a syringe and a connecting element having a first mechanical connection part, a unit such as a needle, a vial, a catheter or an IV line, and an adaptor providing fluid communication between the syringe and the unit and having a second mechanical connection part configured to engage with the first mechanical connection part in an engagement direction, thereby in fully engaged position preventing further relative axial movement between the adaptor and the male tubular projection, wherein the adaptor comprises a sealing element configured to receive the male tubular projection and provide sealing between the male tubular projection and the adaptor.

Abstract: A drug delivery device includes a housing having proximal and distal ends and a longitudinal axis extending therebetween, an injection assembly at least partially disposed within the housing at or near the proximal end, a shield slidably coupled with the housing, a drive assembly operably coupled with the injection assembly and the shield, and a cap. The injection assembly includes a needle or a cannula. The shield is positionable in an extended position in which at least a proximal end thereof extends a distance beyond the proximal end of the housing. The drive assembly is engageable to deliver a medicament via the injection assembly. The cap is removably coupled with at least one of the shield or the housing and is adapted to limit movement of the shield when coupled with the shield and/or the housing such that the drive assembly is restricted from delivering the medicament via the injection assembly.

Abstract: A drug delivery device includes a housing having proximal and distal ends and a longitudinal axis extending therebetween, an injection assembly at least partially disposed within the housing including a needle or a cannula, a drive assembly operably coupled with the injection assembly, a shield slidably coupled with the housing and operably coupled with the drive assembly, and a retention mechanism. The drive assembly is engageable to deliver a medicament via the injection assembly. The shield is positionable in an extended position in which at least a proximal end extends a distance beyond the proximal end of the housing and a retracted position where the proximal end of the housing protrudes a distance beyond the proximal end of the shield. Moving the shield to the retracted position engages the drive assembly to deliver the medicament via the injection assembly.

Abstract: Drug delivery devices and related arrangements are disclosed. A drug delivery device may include a housing having an opening, a drug storage container including a delivery member with an insertion end configured to extend at least partially through the opening, and a plunger. A drive mechanism may be included for driving the plunger in a distal direction to expel a drug from the drug storage container through the delivery member upon activation. The drug delivery device may additionally include a guard moveably disposed adjacent to the opening and operably coupled to the drive mechanism for activation of the drive mechanism. A lock may be selectively engageable with the guard to limit movement of the guard in the proximal direction. An indicator may be coupled to the drive mechanism to generate an audible signal during drug delivery, and to cease generating the audible signal when drug delivery is complete.

Abstract: A damper mechanism for a drug delivery device comprising a frame member, a damper member operably coupled to a drive assembly of the drug delivery device, a damper fluid chamber formed between at least a portion of the frame member and the damper member, and a damper fluid disposed within the damper fluid chamber. The frame member and the damper member rotate relative to each other, and the damper fluid exerts an opposing force on at least one of the frame member and the damper member. The damper fluid chamber includes a main section and an overfill section. The overfill section receives excess damper fluid from the main section to reduce an effect a variation in fill level in the damper fluid chamber has on the opposing force exerted on at least one of the frame member or the damper member.
