Abstract
Flush syringe assemblies are described herein. Such flush syringe assembly may include a barrel including a side wall defining a chamber, a collar mounted on a distal wall of the barrel and surrounding an elongate tip. A cap may be attached to the collar via a hinge. The flush syringe assembly may also include a cap attached to the collar via a hinge. A ring may be disposed around the collar with a locking element that engages with a corresponding mating locking projection on the cap. The cap may include a slanted surface. The slanted surface of the cap may include one or more ribs made of an elastomeric material.
Claims18
A flush syringe assembly comprising:
- a barrel including a chamber for retaining a fluid, an open proximal end, a distal end including a distal wall with an elongate tip extending therefrom having a passageway therethrough in fluid communication with said chamber;
- a collar mounted on the distal wall of the barrel and surrounding the elongate tip, the collar including a compartment, an open distal end, and a proximal end adjacent the distal wall of the barrel;
- a cap attached to the collar via a hinge, wherein the cap includes protrusion that interacts with the elongate tip, a groove disposed on an inside of the cap configured to that engage with a seal of the collar, and a skirt extending in a perpendicular direction from the cap, the skirt dimensioned for sealing engagement with the collar;
- a gasket is disposed between the collar and the cap;
- and
- an plunger rod disposed within the barrel, the plunger rod comprising a rod distal end and a rod proximal end, the rod distal end including a stopper slidably positioned in fluid-tight engagement with an inside surface of the barrel for drawing fluid into and driving fluid out of the chamber by movement of the stopper relative to the barrel, the plunger rod extending from the open proximal end of the barrel.
