A cartridge for use with a beneficial agent delivery device having a fillable reservoir. The cartridge includes a reconstitution, unit dose package having first and second compartments, and a fitment. The first compartment contains at least a first constituent of the beneficial agent. The second compartment contains at least a second constituent of the beneficial agent. The fitment is disposed on the package for interfacing the package to the fillable reservoir.

A prefilled syringe includes a syringe body filled with a medical fluid, which has a nozzle at a front side, the nozzle being closed with a cap, and which is closed at a rear side with a displaceable plunger; and a plunger rod that can be inserted into the syringe body via the rear side. The plunger rod has a connecting portion at a front side, via whi9ch the plunger rod can be connected to the plunger. At least three annular elements, which extend at least in some sections about a longitudinal axis of the rod, are arranged on a rear side of the connecting portion on the plunger rod in such a manner that they are located in the syringe body when the plunger rod is fully connected to the plunger. The three annular elements support a coaxial connection of the rod to the plunger positioned in the syringe.

Described herein are syringe devices comprising a syringe including a therapeutic dose of at least one drug to be used in a drug or substance overdose.

The present disclosure is directed to a device for screening pre-filled syringes configured to determine whether a stopper position within each syringe falls within an acceptable tolerance prior to final assembly of a syringe into a corresponding autoinjector device, thereby ensuring proper fit of the syringe within the autoinjector device and further ensuring accurate delivery of a desired dose of fluid from the syringe during operation of the autoinjector.

A method of manufacturing a cartridge is described. An injection needle is inserted into a mold that forms a barrel. The barrel defines an open proximal end, an opposing distal end, an internal reservoir therebetween, and an arm projecting distally from the distal end of the barrel and having a portion bent at a fixed angle. The injection needle is positioned within a portion of the mold configured to form the arm of the barrel, and a terminal needle tip is oriented such that a beveled opening of the needle tip is distally facing. The injection needle is stabilized against movement with a gripping device. The mold is filled with resin to form the barrel around the injection needle. The gripping device is separated from the injection needle upon hardening of the resin.

A single use pre-filled delivery device is disclosed having a deformable container including a side wall having an inside surface defining a chamber for retaining fluid, a clip element, and a locking element. The deformable container further includes a closed proximal end and an open distal end including a male luer tip having a passageway therethrough providing fluid communication with the chamber. The male luer tip may be removably connectable to a female luer connection of a vascular access device. The clip element includes a distal end, proximal end, and a pivot located between the distal end and the proximal end of the clip element for collapsing the deformable container to drive fluid out of the chamber by movement of the proximal end towards the distal end. The pivot may be a hinge, which may be in the form of a living hinge. The deformable container may be attached to the clip element. The locking element may be disposed on the clip element. A method of administering a fluid to a vascular access device using a single use pre-filled delivery device as described herein is also disclosed.

The present disclosure provides methods of preparing a medical solution. In some aspects, the medical solution can be prepared from mixing a first liquid with a second liquid or mixing a solid component with a liquid in an autoinjector. In some aspects, the heat released from the mixing can promote solubility of a dry medicament in the solution.

The invention relates to a piston stopper (10) for a medical syringe (1) wherein the piston stopper (10) has an end wall (11), a lateral wall (12) and an internal thread (16) for securing a piston rod (7). The piston stopper (10) comprises a main body (10a) which made of a cycloolefin, in particular a cycloloefin copolymer or a cycloolefin polymer. A plurality of sealing rings (13a-13d) that are made from a plastic material extend around the main body of the piston (10) and are materially bonded to the main body of the piston (10a). The invention furthermore relates to a medical syringe (1) and to a method for the production thereof.
