Abstract

Syringe assemblies and adapters for syringes that attach to and allow non-native syringes to be accepted by injectors having injector syringe interfaces adapted for particular types of syringes are described herein. Methods of forming the syringe assemblies, and kits including the syringe adapters which enable a non-native syringe to be operably attached to an injector are also described.

First claim

What is claimed is:

1. A syringe assembly for connecting a syringe to an injector, the syringe assembly comprising:
a first section defining an open slot;
a detached second section shaped to slide into and seat within the open slot;
a seating having a front abutment and a rear abutment, the seating formed on the first section, the first section comprising a rearward portion configured to operably connect the syringe assembly to an injector syringe interface, the rearward portion further comprising indicators arranged to cooperate with a sensing system and positioned at predetermined positions to reflect light; and
snap connectors for joining the first section and the second section,
wherein the seating is configured to receive and seat at least a portion of a flange of the syringe between the front abutment and the rear abutment.

2. The syringe assembly of claim 1 , wherein the snap connectors comprise mechanical connectors for joining the first section and the second section.

3. The syringe assembly of claim 1 , wherein the assembly attaches to the syringe at a nonzero angle relative to a longitudinal axis of a barrel of the syringe.

4. The syringe assembly of claim 1 , wherein the assembly attaches to the syringe at an angle generally perpendicular to a longitudinal axis of a barrel of the syringe.

5. The syringe assembly of claim 1 , wherein the first section and the second section are formed from a polymeric material.

6. The syringe assembly of claim 1 , wherein the open seating receives the flange such that the syringe cannot rotate relative to the assembly.

7. The syringe assembly of claim 1 , further comprising a passage formed when the first section and second section are engaged, the passage being capable of operatively connecting to a barrel of the syringe and allowing a drive member to pass through the passage and operably contact to a plunger slidably positionable within the barrel.

8. The syringe assembly of claim 1 , wherein the rearward portion comprises a mounting flange.

9. The syringe assembly of claim 1 , wherein the rearward portion comprises a projecting tab to enable release of the assembly from the injector syringe interface.

10. The syringe assembly of claim 1 , wherein the rearward portion comprises a radially extending ledge.

11. The syringe assembly of claim 1 , wherein the indicators indicate the configuration of the syringe to the injector.

12. The syringe assembly of claim 1 , wherein the indicators correspond to a binary code.

13. The syringe assembly of claim 1 , wherein the syringe assembly is formed of a polymeric material which is optically translucent.

14. The syringe assembly of claim 1 , further comprising a plunger adaptor.

15. The syringe assembly of claim 1 , wherein removal of the first section from the second section results in breakage.

16. The syringe assembly of claim 1 , wherein removal of the first section and the second section from the syringe results in breakage.

17. The syringe assembly of claim 1 , wherein the second section comprises at least one lateral extending section adapted to slide into and seat within the open slot.

18. A method of forming a syringe assembly comprising:
providing a syringe having a barrel, a front end outlet in fluid connection with the barrel, and a rear end flange;
providing an adapter comprising at least a first section defining an open slot, a detached second section shaped to slide into and seat within the open slot, and a seating having a front abutment and a rear abutment, the seating formed on the first section, the first section engageable with the second section by snap connectors for joining the first section and the second section, the first section further comprising a rearward portion configured to operably connect the syringe assembly to an injector syringe interface, the rearward portion further comprising indicators arranged to cooperate with a sensing system and positioned at predetermined positions to reflect light;
seating the rear end flange of the syringe in the seating; and
sliding the second section into the open slot in the first section to form an engagement between the at least first section and the second section thereby connecting the adapter to the syringe,
wherein the rear end flange of the syringe is seated between the front abutment and the rear abutment of the seating.

19. The method of claim 18 , wherein removal of the first section and the second section from the syringe results in breakage.

20. The method of claim 18 , wherein the indicators indicate the configuration of the syringe to the injector.

21. The method of claim 18 , wherein the indicators correspond to a binary code.

22. The method of claim 18 , wherein the syringe assembly is formed of a polymeric material which is optically translucent.

23. The method of claim 18 , wherein the second section comprises at least one lateral extending section adapted to slide into and seat within the open slot.

24. A kit to enable a syringe to be operably connected to an injector, the kit comprising:
an adapter comprising at least a first section defining an open slot, a detached second section shaped to slide into and seat within the open slot, and a seating having a front abutment and a rear abutment, the seating formed on the first section, the first section being engageable with the second section, the first section comprising a rearward portion configured to operably connect the adapter to an injector syringe interface, the rearward portion further comprising indicators arranged to cooperate with a sensing system and positioned at predetermined positions to reflect light; and
snap connectors for joining the first section and the second section,
wherein the seating is configured to receive and seat at least a portion of a flange of the syringe between the front abutment and the rear abutment.

25. The kit of claim 24 , wherein removal of the first section from the second section results in breakage.

26. The kit of claim 24 , wherein removal of the first section and the second section from the syringe results in breakage.

27. The kit of claim 24 , further comprising a plunger adaptor.

28. The kit of claim 24 , wherein the indicators indicate the configuration of the syringe to the injector.

29. The kit of claim 24 , wherein the indicators correspond to a binary code.

30. The kit of claim 24 , wherein the adapter is formed of a polymeric material which is optically translucent.

31. The kit of claim 24 , wherein the second section comprises at least one lateral extending section adapted to slide into and seat within the open slot.
