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.

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 invention relates to an opening and liquid supplying system (100) for pre-filled containers (10, 30) equipped with a supplying end, comprising a coupling element (20), connecting means (6) movable from a first position to a second position, and movable protection means (9); the coupling element (20) has an end (27) closed and suitable for being punched, and first guiding means (21) for guiding the movement of the connecting means (6) movable from the first position, close to the closed end (27), to the second position, apart from such end, and vice versa; the connecting means (6) have engaging means (7) for engaging with the protection means (9) so as to move integrally along a second degree of freedom, different than the first degree of freedom, and first matches (11) for the first guiding means (21). The invention relates also to a respective pre-filled container equipped with such system and the method for realize them.

Apparatus for removably attaching a syringe to a container for extracting fluid therefrom into the syringe, which is particularly beneficial for fluid having a relatively high viscosity. The disclosed container adapter holds a syringe adapter securely therein (the syringe adapter configured for providing a fluid path between a container and a syringe) while also securing the syringe adapter to the container, and provides an attachment point for securely attaching the syringe to the syringe adapter and thus to the container (at least) while the fluid is withdrawn from the container into the syringe. The syringe is removably attached to an end of the syringe adapter during the withdrawal, and a cap is provided that closes entry and exit to this attachment point when the syringe is not in place. The cap preferably attaches to the syringe adapter using a connection that mimics the connection used by the syringe.

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.

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.
