Abstract

Syringes for use with medical fluid injectors. In certain aspects, the syringe includes a body having a longitudinal axis, a forward end, and a rearward end. At least one syringe mating section is coupled to the body of the syringe and is adapted to operatively engage an injector. In some embodiments, the syringe mating section includes first, second, and third flanges extending outwardly from the body along a plane substantially perpendicular to the longitudinal axis. In some embodiments, the syringe mating section includes a first flange having a cross-section of a parallelogram and a second flange having a tapered surface. In some embodiments, the syringe mating section includes a flange having an L-shaped cross-section. Other embodiments of the syringe mating section may include yet other appropriate designs.

Claims

1. (canceled)

2. A syringe comprising:

a body having a longitudinal axis and including a forward end and a rearward end, the forward end having a fluid discharge section defined therein; and

a first syringe mating section coupled to the body, the first syringe mating section comprising first and second flanges extending outwardly from the body away from the longitudinal axis along a plane substantially perpendicular to the longitudinal axis, wherein the first flange has a cross-section in the form of a parallelogram, and wherein the second flange includes a tapered surface relative to the longitudinal axis.

5. The syringe of claim 2, wherein at least one flange extends only partially circumferentially around the body.

6. The syringe of claim 2, wherein at least one flange does not exhibit any discontinuity along its length.

7. The syringe of claim 2, wherein at least one flange exhibits at least one discontinuity along its length.

8. The syringe of claim 2, wherein at least one flange does not have a cavity disposed therein.

9. The syringe of claim 2, further comprising:

a second syringe mating section coupled to the body and positioned substantially opposite the first syringe mating section.

10. The syringe of claim 2, wherein the first syringe mating section has an area of at least about 0.2 square inch.

11. The syringe of claim 2, further comprising:

a plunger movably disposed in the body.

12. The syringe of claim 2, wherein the plunger comprises a projection extending rearwardly therefrom.

13. The syringe of claim 2, wherein the first flange is located distally of the second flange.

14. The syringe of claim 2, wherein the first flange is located proximally of the second flange.

15. An injection system comprising:

a medical fluid injector; and

a syringe of claim 2 mounted to the injector.

16. The injection system of claim 15, wherein the first syringe mating section is engaged with a housing of the injector.

17. The injection system of claim 15, wherein the first syringe mating section is engaged with a face plate of the injector.

18. The injection system of claim 15, wherein the injector includes an injector mating section designed to interface with the first syringe mating section of the syringe.

19. The injection system of claim 18, wherein the injector mating section defines a contour that confronts the first syringe mating section.

20. The injection system of claim 19, wherein the contour defines at least one groove.

3. (canceled)

4. The syringe of 2, wherein at least one flange is located toward the rearward end of the body.
