Abstract

Disclosed is a medical device used to prevent the cross contamination of patients or injectors.

Claims

1. An injector assembly, comprising:

a) an injector having a proximal end and a distal end, the injector comprising an injector orifice at the distal end;

b) a first component, the first component having an orifice therethrough, the first component generally located at the injector distal end;

c) a second component, the second component having an orifice therethrough, the second component generally located at the injector distal end; and

d) a protective layer generally located at the injector distal end covering at least one of the injector orifice, the first component orifice, or the second component orifice;

wherein the first component, the second component, and the protective layer are configured at the distal end of the injector to block the splashback of debris from entering the injector orifice during and/or after injection.

2. The injector assembly of claim 1, wherein the first component is a baffle.

3. The injector assembly of claim 1, wherein the first component is an insert.

4. The injector assembly of claim 1, wherein the second component is a baffle.

5. The injector assembly of claim 1, wherein the second component is an insert.

6. The injector assembly of claim 1, wherein the first component is proximal to the second component.

7. The injector assembly of claim 1, wherein the protective layer is proximal to either the first component or the second component.

8. The injector assembly of claim 1, wherein the protective layer is proximal to the first and second components.

9. The injector assembly of claim 1, wherein the protective layer is proximal to the second component and distal to the first component.

10. The injector assembly of claim 1, wherein the protective layer covers at least one of the first component orifice and the second component orifice.

11. The injector assembly of claim 1, wherein the injector assembly includes a plurality of protective layers.

12. The injector assembly of claim 11, wherein at least one of the plurality of protective layers is distal to the first or second component.

13. The injector assembly of claim 1, wherein the first component is a baffle, the second component is an insert, and the protective layer is distal to the first component.

14. A medical device, comprising:

a) a first component, the first component having an orifice therethrough;

b) a second component, the second component having an orifice therethrough, the second component being partially distal to the first component;

c) an intermediate piece; and

d) a protective layer, the protective layer located generally between the intermediate piece and the second component orifice.

15. The medical device of claim 14, wherein the intermediate piece further comprises a connector component.

16. The medical device of claim 15, wherein the connector component further comprises at least one of a friction fit, bayonet, and screw type connector.

17. The medical device of claim 16, wherein the intermediate piece further comprises a connector component at each end of the intermediate piece.

18. The medical device of claim 15, wherein the intermediate piece further comprises a connector component at each end of the intermediate piece.

19. The medical device of claim 14, wherein the assembly further comprises an injector.

20. The medical device of claim 19, wherein the injector further comprises a connector component.

21. The medical device of claim 20, wherein the injector connector component is adapted to engage the intermediate piece.

22. The medical device of claim 20, wherein the protective layer is distal to the injector.

23. The medical device of claim 22, wherein the intermediate piece further comprises an orifice extending therethrough.

24. The medical device of claim 23, wherein the intermediate piece orifice is generally coincident with the first and second component orifices.

25. The medical device of claim 24, wherein the protective layer is distal to the injector and proximal to either the first or second component.

26. An injector assembly, comprising:

a) an injector having a proximal end and a distal end, the injector comprising an injector orifice at the distal end;

b) a first component, the first component having an orifice therethrough, the first component generally located at the injector distal end;

c) a second component, the second component having an orifice therethrough, the second component generally located at the injector distal end; and

d) a plurality of protective layers generally located at the injector distal end.

27. The injector assembly of claim 26, wherein at least one of the plurality of protective layers is distal to the first or second component.

28. The injector assembly of claim 26, wherein at least one of the plurality of protective layers is proximal to the first or second component.

29. The injector assembly of claim 26, wherein at least one of the plurality of protective layers is integrally formed with at least one of the first component or the second component.
