  • Method for manufacturing a syringe
    Patent number: 7951120
    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.
