The disclosure relates to a syringe, comprising a syringe body with a nozzle and a threaded connection. The syringe body comprises a side wall and a front wall, wherein the syringe body comprises a cycloolefin as a first material, at least in portions. The first material forms an internal wall of the syringe body. The threaded connection comprises, at least in portions, as a second material a material other than the cycloolefin, wherein the first and the second material are integrally bonded to one another. The second material extends in the region of the front wall at least in portions over the first material, so that the front wall comprises, at least in portions, a two-layer region. The first and the second material in the two-layer region have a mutually engaging structure.

A pre-filled medical delivery assembly assembled and configured to allow delivery of a single dose of a therapeutic agent (e.g., vaccine, drug, medicament, etc.) from a Blow-Fill-Seal (BFS) vial to a patient. The delivery assembly generally includes a modular design consisting of separately constructed components cooperatively arranged and coupled to one another.

A syringe barrel includes: a barrel body including a nozzle portion at a distal end thereof; and a cap removably mounted to the nozzle portion and configured to seal a distal end opening of the nozzle portion. The cap includes: an inner cap formed of an elastic material and configured to come in liquid tight contact with the nozzle portion in a mounted state in which the cap is mounted to the nozzle portion, and a cylindrical outer cap formed of a material having a higher hardness than the inner cap and fixed around the inner cap. The inner cap includes: a base portion, and a cylindrical wall extending from the base portion in a proximal direction and surrounding the nozzle portion.

A mixing vial having a hollow interior chamber with a tubular portion having distal and proximal open ends and a stopper positioned in sealing relationship in the tubular portion, the stopper having a hollow interior chamber with an open end and a dislodgeable plug positioned in and sealing the open end.

A method for assembling a drug delivery device that includes mounting a cartridge with a bung, the mechanism, the plunger and the spring within a housing such that a spring biases a plunger in a dispensing direction and that a drum and/or the release member is attached to the plunger attaching a tool with torque measurement capability to the drum or a release member of a dose mechanism in a state where at least one housing part is detached from further housing part; setting a dose by rotating the dose setting member in a first direction, activating a trigger and monitoring the torque applied to the drum or the release member; releasing the trigger upon detection of a predetermined change in the torque measured by the tool; and releasing the tool and closing the housing.

A syringe holder includes: a barrel body that holds a syringe; a holder opening; deformation promoting portions; and radial movement-restricting portions. The radial movement-restricting portions are provided close to the deformation promoting portions. Being brought into contact with first portions, the radial movement-restricting portions restrict the syringe from moving in a radial direction with respect to the barrel body.

A system for injecting includes a syringe body defining a proximal opening and a distal needle interface. The system also includes a plunger member defining a plunger interior and configured to be manually manipulated to insert a stopper member relative to the syringe body. The plunger member includes a needle retention feature disposed in the plunger interior, an energy-storage member disposed in the plunger interior, and an energy-storage member latching member disposed in the plunger interior. The system further includes a needle hub assembly coupled to the distal needle interface of the syringe body. The needle assembly includes a needle having a needle proximal end feature, a hub, and a needle latching member configured to couple the needle to the hub. The needle is retractable into plunger interior upon manipulation of the plunger member to actuate the energy-storage member latching member.

A fluid delivery device includes a housing having a bottom surface configured to be coupled to the skin surface. The fluid delivery device includes a cartridge prefilled with a fluid and configured to be inserted into the housing. The cartridge has a septum configured to be generally perpendicular to the bottom surface when the cartridge is inserted in the housing. The fluid delivery device includes a needle assembly that has a needle that includes a fluid coupling end and a delivery end. The fluid coupling end of the needle is fluidly disengaged from the cartridge in an initial position. The delivery end of the needle extends past the plane of the bottom surface and the fluid coupling end of the needle extends through the septum in a deployed position.
