摘要： A syringe assembly for use as a pre-filled syringe is disclosed. The syringe assembly includes a syringe barrel defining a chamber and having a stopper disposed therein. A plunger rod includes an inner member engaged with a portion of the stopper and an outer member adapted for rotational advancement with respect to the inner member to axially displace the outer member with respect to the inner member. The plunger rod is transitionable from a collapsed position in which a portion of the inner member is nested within the outer member, to an extended position in which the same portion of the inner member extends outside the outer member. The inner member includes a radial extension and the outer member defines a helical track adapted to receive the radial extension therein.

摘要： A syringe assembly including a syringe barrel defining a chamber having a stopper therein is disclosed. The syringe assembly includes a plunger rod associated with the stopper, the plunger rod includes an outer sleeve having a distal end interconnected to the stopper and a sidewall portion defining an opening therein. The plunder rod also includes an inner sleeve disposed within the outer sleeve including a longitudinally extending track in alignment with the opening in the outer sleeve. The inner sleeve is adapted for telescopic movement with respect to the outer sleeve. The plunger rod also includes a spring mounted in association with the inner sleeve. The syringe assembly further includes a holding mechanism associated with the plunger rod and configured for cooperation with the inner and outer sleeves. Relative movement between the inner and outer sleeves causes the plunger rod to transition from a collapsed position to an extended position.

摘要： A syringe assembly including a syringe barrel having a first end, a second end, and a sidewall extending therebetween defining a chamber is disclosed. The syringe assembly includes a stopper disposed within the chamber of the syringe barrel and a plunger rod having an inner member engaged with the stopper and an outer member adapted for telescopic movement with respect to the inner member. The plunger rod is transitionable from a collapsed position, in which a portion of the inner member is nested within the outer member, to an extended position, in which the same portion of the inner member extends outside the outer member. The syringe assembly also includes a stop member configured for cooperation with a portion of the syringe barrel, upon relative movement of the outer member with respect to the inner member, to limit the outward travel of the plunger rod from the syringe barrel.

摘要： A syringe assembly including a plunger rod having a first end, a second end, and a rod portion extending therebetween, wherein at least a portion of the rod portion is flexible is disclosed. The flexible portion of the rod portion allows a stopper to be moved between a first position and a second position within a syringe barrel while the overall length of the syringe assembly remains the same throughout the movement between the first position and the second position. In another embodiment, a syringe assembly including a restraining member adapted to communicate with the flexible portion of the rod portion such that movement of the first end of the plunger rod in a first direction actuates movement of the second end of the plunger rod in a second direction different than the first direction is disclosed.
