Abstract
A syringe for an injector that has at its nozzle end a connection to the fluid delivery tubing that prevents, reduces, or eliminates fluid leaks, by virtue of a ridge on the external surfaces of the connector which engage to tubing. Furthermore, the syringe and injector are configured to permit the syringe to be oriented in more than one manner on the injector.

A syringe comprising:
- a syringe case comprising:
- a proximal end and an opposing remote end;
- a discharge neck located at the remote end of the syringe case;
- and
- tubing connector located at a remote end of the discharge neck, the tubing connector comprising:
- a taper comprising a proximal end, an opposing distal end, and an annular first ridge disposed about a peripheral circumference of the taper;
- and
- an internal threaded section disposed about the taper;
- and
- a plunger disposed within an internal cavity of the syringe case.

- an injector;
- and
- a syringe mounted to the injector, the syringe comprising:
- a unitary, single piece syringe case comprising:
- a proximal end and an opposing remote end;
- a discharge neck located at the remote end of the syringe case;
- and
- tubing connector located at a remote end of the discharge neck, the tubing connector comprising:
- a taper comprising a proximal end, an opposing distal end, and an annular first ridge disposed about a peripheral circumference of the taper;
- and
- an internal threaded section disposed about the taper;
- and
