Disclosed is a fluid injection device for a needle free syringe is provided that is spring-loadable and comprises a trigger positioned within the housing and actuated by depression of a push-button disposed opposite the dispensing end at an external actuation surface disposed transverse to the injection axis. The trigger has a trigger latch configured to release a trigger catch as heaving part of the spring-loaded piston of the device. The trigger catch is configured to urge the trigger latch in a direction transverse to the injection axis when the piston moves from the unloaded position to the loaded position. The compression spring is retained around the piston and retained within the housing by a piston head. The device further comprises a syringe adapter and a safety cap which prevents accidental triggering.

The disclosure refers to a packaging container (81, 281) comprising a tubular housing (83, 283) and a plunger stopper (82, 282) moveable within the housing (83, 283), wherein at least a section of an outer surface of the plunger stopper (82, 282) being in contact with an inner surface of the housing (83, 283) comprises a silicone-free coating (88, 288) which reduces break loose and/or gliding forces. The disclosure further describes a system comprising this packaging container (81, 281) and a formulation (87, 287) within the packaging container containing one or more pharmaceutically active compound and/or carrier as well as a drug delivery device comprising this system.

The invention provides a pen-type injection device (1) with a piston rod brake mechanism for improving the determination of an expelled dose.

A pen includes a carpule having a longitudinal axis, a first end with a dispensing opening closable by a closure part, a second end via which at least one stopper can be inserted in the direction of the longitudinal axis, and an interior that is tightly closed by the closure part and the at least one stopper. A pen housing has a central axis, receives the carpule, and has a piston rod that interacts with the at least one stopper and a drive for moving the at least one stopper within the interior of the carpule, wherein the second end of the carpule can be inserted into the housing. The drive element moves the carpule into the housing in the direction of the longitudinal axis, which is arranged coaxially to the central axis of the housing, when the drive is activated; and in the process the piston rod is held in a fixed position with respect to the longitudinal direction of the housing such that the piston rod, which is engaged in the second end of the carpule, moves the at least one stopper within the interior of the carpule in the direction of the first end of the carpule.

The present disclosure relates to an assisted injection device for injecting a composition contained in a medical container. The injection device includes a body adapted to receive a medical container in a fixed position relative to the body. The injection device includes a spring-loaded piston rod translationally movable inside the body between a proximal rest position allowing inserting of the medical container in the body and a distal operative position wherein the piston rod engages a stopper of the medical container and pushes the stopper in the medical container. The injection device includes a blocking system comprising a locking member mounted on the body and configured to engage the piston rod. The piston rod includes a proximal end extending out of the body and configured to be pushed by the user in a distal direction to accelerate the movement of the piston rod to the distal operative position.

The present disclosure relates to an assisted injection device for injecting a composition contained in a medical container. The injection device includes a main body adapted to receive a medical container in a fixed position relative to the main body. The main body includes an inner wall part and a second part. The first part includes an inner spring-loaded piston rod, and an outer piston body extending coaxially around the inner spring-loaded piston rod. The second part is arranged between the inner spring-loaded piston rod and the outer piston body, and is provided of the piston. The actuator is adapted to selectively move the second part between the proximal first portion and the distal second position.

The present disclosure relates to an assisted injection device for injecting a composition contained in a medical container. The injection device includes a body configured to receive the medical container in a fixed position relative to the body. The injection device includes a spring-loaded piston rod translationally movable inside the body along a spring axis. The injection device includes a lever pivotably mounted on the body about a first pivot axis orthogonal to the spring axis at a first distance form the spring axis. The injection device includes a selective blocking system coupled to the lever by a second pivot axis orthogonal to the spring axis. The lever is pivotable between a rest position. The selective blocking system engages the piston rod to prevent any translation movement of the piston rod and a second position wherein the selective blocking system releases the piston rod.

An injection device including a syringe including a barrel having a distal end and a proximal end and a tip provided on the distal end of the barrel, the barrel defining an internal bore extending from the proximal end to the distal end of the barrel; a luer lock adaptor including a body having a proximal end and a distal end, a reduced-diameter portion provided on the proximal end of the body, and a threading provided on an outer surface of the body, the reduced-diameter portion defining an opening to receive the tip of the syringe in a friction fit; and a needle hub including a body defining an inner cavity, a needle receiving portion extending distally from the body, and a skirt extending inwardly into the inner cavity.

A cartridge holding unit includes a cartridge container forming an outer surface of the cartridge holding unit and having an inner space, and a cartridge holder forming a tube-shaped holding section arranged in the inner space of the cartridge container, the cartridge holder configured to firmly hold a cartridge in parallel with the cartridge holder and the cartridge holder and the cartridge container are firmly coupled to each other regarding their axial orientations.

An adapter for use with a drug delivery device having a reservoir for containing a product, the reservoir having a distally projecting end-piece defining a passageway for the transfer of the product from the reservoir, includes a collar engageable with the end-piece, an adaptor securing member limiting translational movement of the collar with respect to the end-piece once the collar is engaged with the end-piece, at least one adaptor anti-rotation member limiting the rotation of the collar with respect to the end-piece once the collar is engaged with the end-piece, at least one deactivating member neutralizing the adaptor anti-rotation member in response to a turning torque equal or greater than a predetermined value applied to the collar when the collar is engaged with the end-piece, thereby allowing the rotation of the collar with respect to the end-piece.
