Abstract: A syringe has a syringe barrel into which a plunger stopper is inserted during a manufacturing process. A plunger rod is connected to the plunger stopper, and a backstop for preventing inadvertent removal of the plunger stopper from the syringe barrel is arranged at the proximal end of the syringe barrel. The backstop and the plunger rod are configured to form a combined assembly component which is adapted to be mounted to the syringe barrel in a combined manufacturing step. After mounting the combined assembly component to the syringe barrel, the backstop and the plunger rod are separated to allow conventional use of the syringe.

Abstract: A syringe with a closure is disclosed. The syringe comprises a needle projecting from a syringe body, the tip of the needle being enclosed by a closure cap when the syringe is in a closed position. A sealing element is provided for sealing the needle in the closed position. The sealing element has an annular, elastically deformable portion that can be sealingly pressed against the outer surface of the needle by means of the closure cap.

Abstract: A method for producing a multi-chamber syringe with a by-pass channel from a plastic material comprises the steps of producing a tubular preform from a thermoplastic material; providing a die designed to enclose the preform from the outside in an area of the by-pass channel to be formed, the at least one by-pass channel being preformed as a recess on an inner surface of the die; heating-up the preform to a temperature above the softening range of the plastic material, and positioning the preform in a predefined axial position inside the die; subjecting the preform to a differential pressure until the at least one by-pass channel is plastically formed; and cooling down the syringe body so formed to room temperature.

Abstract: An arrangement for storing, transporting and administering a liquid, such as a medical liquid, comprises a syringe barrel. The proximal end of the syringe barrel is closed with a proximal closure element. At the distal end, there is a distal closure element. The two closure elements are connected to one another in a clip-like fashion via a connection element. At least one predetermined breaking point is provided between the two closure elements and the connection element. Thus, a tamper-evident closure for a syringe is formed.

Abstract: A syringe has a syringe barrel comprising a proximal end and a distal end. At the proximal end there is a backstop with which a plunger stopper arranged in the syringe barrel is secured against inadvertent withdrawal. The backstop has at least two claw-like catch hooks arranged outside the syringe barrel at mutually offset circumferential positions. According to one aspect of the invention, the catch hooks are arranged on a plate-shaped finger support sitting at the proximal end of the syringe barrel.
