AI Technical Summary

Benefits of technology

The present invention relates to a syringe assembly and a plunger rod assembly that can be used with the syringe assembly. The plunger rod assembly includes an inner member and an outer member that can be rotated with respect to the inner member to displace the outer member with respect to the inner member. The plunger rod assembly can be transitioned from a collapsed position to an extended position. The syringe assembly includes a stopper and a chamber for containing a medication or drug. The technical effects of the invention include improved ease of use, improved injection accuracy, and reduced injection force.

Problems solved by technology

The space within these controlled storage locations is often limited, thus there is a need for a syringe assembly that has a smaller packaging footprint to reduce the storage space required for containing this syringe.

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to U.S. Provisional Patent Application No. 61 / 541,370 filed Sep. 30, 2011, the entire disclosure of which is hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is directed to a pre-filled syringe assembly adapted for the dispensing and delivery of a fluid. More particularly, the present invention is directed to a pre-filled syringe assembly having a rotatably advanceable plunger rod which results in a smaller packaging footprint allowing for reduced storage space.[0004]2. Description of Related Art[0005]Syringe assemblies, and in particular hypodermic syringes, are well known in the medical field for dispensing fluids, such as medication. A conventional syringe typically includes a syringe barrel with an opening at one end and a plunger mechanism disposed through the other end. The plunger mechanism typically includes a plunger rod extendin...
