The present disclosure relates to a data logging device for monitoring an injection device, the injection device including a housing and a movable part movable between a first end position and a second end position, the data logging device including a trigger connectable to at least one of the movable part and the housing, a switch arrangement including a first switch engaged with the trigger and movable between a first trigger end position and a second trigger end position, the switch arrangement operable to switch between a first switching state and a second switching state upon movement of the trigger, and a processor connected to the switch arrangement and operable to detect a transition of the switch arrangement between the first switching state and the second switching state.

An automatic applicator for liquid pharmaceutical preparations, particularly for multiple injection application of set doses of a medicine from an exchangeable container is provided. The automatic applicator includes a body housing connected to a housing of an exchangeable container with a medicine having a plunger, the said plunger being displaced only linearly by an integrated driving unit, suitable for immobilizing, driving, leading linearly and blocking rotation of the plunger, driven via a double action clutch, by a tensioning spring situated in the body housing, the spring tensioned by a rotary hand-dose-setting ring via the double action clutch, wherein the driving unit is activated by a trigger unit and a dose is indicated by an indicating arrangement. The automatic applicator further includes at least one block key placed in an upper part of a ratchet barrel, collaborating with at least one key placed in an internal part of the body housing.

An assembly for a drug delivery device is provided, the assembly including a blocking element and a piston rod having an interaction feature adapted and arranged to mechanically cooperate with the blocking element. For delivering a dose of a drug, the piston rod is configured to be moved from an initial position to an end position with respect to the blocking element, wherein the interaction feature is provided along the path between the initial position and the end position. An operating noise is provided to the user when the interaction feature mechanically cooperates with the blocking element while moving the piston rod for dose delivery. The interaction feature is adapted for homogenizing the operating noise so as to prevent the operating noise from being interpreted by the user as signalling the end of the dose delivery operation. Furthermore, a drug delivery device is provided.

Described herein are syringe devices comprising a syringe including a therapeutic dose of at least one drug and a stopper. The syringe is housed and/or placed in an encasement. The plunger assembly can include a plunger, an actuator, and a spacer, wherein the plunger assembly is configured to move the stopper a predetermined distance without a user touching the plunger. Methods of assembling and using the syringe devices are also described.

An assembly for a drug delivery device (1) comprises a housing (5), a rotation member (15), a drive member (16) and at least one correction member (7). The rotation member (15) is adapted to be rotated with respect to the housing (5) in a first rotational direction for delivering a dose of a drug (11). The drive member (16) is coupleable to the rotation member (15) for delivering the dose. In a delivery mode, the drive member (16) and the rotation member (15) are coupled such that the drive member (16) follows rotational movement of the rotation member (15) in the first rotational direction due to mechanical interaction of the rotation member (15) and the drive member (16). In a correction mode, the rotation member (15) and the drive member (16) are decoupled such that the rotation member (15) is rotatable in the first rotational direction with respect to the drive member (16). For switching from the delivery mode into the correction mode, the correction member (7) is moveable with respect to the housing (5), wherein the assembly is configured such that movement of the correction member (7) with respect to the housing (5) is converted into a relative movement between the drive member (16) and the rotation member (15) for decoupling the drive member (16) and the rotation member (15).

An auto-injector device for administering a liquid pharmaceutical composition, in which an end-user can select between doses that the device is capable of delivering. The end-user choices that translate into the selected doses can be based on end-user perceived severity of symptoms, end-user weight and other such factors. In some embodiments the auto-injector is configured to administer the one chosen dose only. In other embodiments, the auto-injector can deliver second and subsequent doses up to full dose of the pharmaceutical composition disposed in the injector. The auto-injector can provide visual, audio, and tactile feedback, alone or in combination, to the user to indicate the dose selected, instructions for use, and when the dose has been administered.

A drive mechanism for a medication delivery device is presented having a housing, a rotation member that rotates in a first direction with respect to the housing during setting of a dose of a medication and rotates in a second direction with respect to the housing during delivery of the dose, the second direction being opposite to the first direction. The device also has a piston rod that is displaced in a distal direction with respect to the housing for delivering the dose, a drive member which follows rotational movement of the rotation member in the second direction during delivery of the dose, and a stop member which prevents rotational movement of the drive member with respect to the housing in the first direction during setting of the dose.

A pen-type drug injection device is disclosed which comprises a housing having a longitudinal axis, a threaded piston rod, a guide member for guiding the piston rod in a drug dispense operation, and a cartridge holder for receiving a cartridge, wherein the cartridge holder is detachable from the housing and wherein the guide member comprises an iris type aperture defined by a plurality of threaded pivotable segments. The drug delivery device is configured such that the aperture increases in diameter when the cartridge holder is being detached from the housing, such that the piston rod is free of the threaded engagement with the guide member and can be reset or pushed back to its initial position, and decreases in diameter when the cartridge holder is attached, such that the threads on segments reengage the piston rod.

An assembly for a drug delivery device comprises a housing, a rotation member, a drive member and at least one correction member. The rotation member is adapted to be rotated with respect to the housing in a first rotational direction for delivering a dose of a drug. The drive member is coupleable to the rotation member for delivering the dose. In a delivery mode, the drive member and the rotation member are coupled such that the drive member follows rotational movement of the rotation member in the first rotational direction due to mechanical interaction of the rotation member and the drive member. In a correction mode, the rotation member and the drive member are decoupled such that the rotation member is rotatable in the first rotational direction with respect to the drive member.
