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.
