Angiographic syringe and luer connector
First Claim
1. A syringe assembly for injecting fluids into the body of an animal through tubing, the assembly comprising:
- a syringe having a tubular body portion, a discharge end portion and a piston disposed for sliding movement within said tubular body portion, said discharge end portion having a narrow tubular extension defining a tip of the discharge end portion, a series of external threads spaced proximally from the tubular extension and a circumferential area free of threads spaced proximally of said external threads; and
,a tubular connector member having internal threads at a first end and tubing connecting structure at a second end, wherein said internal threads are engageable with the external threads of the syringe discharge end and are configured to be received about said circumferential area when the internal threads are rotated past the external threads of said syringe for allowing free rotation of said tubular connector with respect to the syringe discharge end.

Abstract
A syringe discharge end having a rotatable tubular connector member for engaging a luer connector on medical tubing. The syringe discharge end and the connector have mating threads which are used to affix the connector to the syringe discharge end. Once affixed, the connector is may freely rotate relative to the syringe, while being prevented from axial movement. On its distal end, the connector includes internal threads for engaging external threads on a standard luer connector of medical tubing. To engage the connector to tubing, the connector is rotated relative to the tubing and the syringe to draw the tubing onto the syringe discharge end.
