Abstract

An applicator assembly for mixing at least a first and a second component is provided. The applicator assembly includes a manifold configured for operable engagement with first and second source of component, the manifold including first and second component channels therethrough, an elongated shaft extending distally from the manifold, the elongated shaft including first and second component lumens extending the length thereof, the first and second component channels in fluid communication with the first and second component lumens, a tip assembly defining a first chamber, an intermediate chamber and a final chamber, wherein the first chamber is configured to receive a distal end of the elongated shaft, the second chamber is configured to receive an insert, and the final chamber is configured to receive the first and second components prior to the mixture being ejected from an outlet defined in the distal end of the tip assembly

Claims

1. An applicator assembly comprising:

a manifold configured for operable engagement with at least a first and a second source of component, the manifold including at least a first and a second component channel therethrough;

an elongated shaft extending distally from the manifold, the elongated shaft including at least a first and a second component lumen extending the length thereof, the at least first and second component lumens in fluid communication with the at least first and second component channels;

a tip assembly defining a first chamber, an intermediate chamber and a final chamber, wherein the first chamber is configured to receive a distal end of the elongated shaft, the second chamber is configured to receive an insert, and the final chamber is configured to receive the at least partially mixed at least first and second components prior to the mixture being ejected from an outlet defined in the distal end of the tip assembly.

2. The applicator assembly of claim 1, wherein the elongated shaft includes a flexible wire extending the length thereof.

3. The applicator assembly of claim 1, wherein the manifold and elongated shaft are integrally formed.

4. The applicator assembly of claim 1, wherein the intermediate chamber includes ribs for maintaining the insert in a spaced relationship from a wall of the chamber.

5. The applicator assembly of claim 1, wherein the outlet is configured to eject the mixture from the tip assembly as a spray.

6. The applicator assembly of claim 1, further including at least a first slot formed between the intermediate chamber and the final chamber configured to direct the at least first and second components radially inward.

7. The applicator assembly of claim 6, including three or more slots.

8. The applicator assembly of claim 6, wherein the at least first slot is configured to cause the swirling of the at least first and second components within the final chamber.

9. The applicator assembly of claim 1, wherein the insert includes a substantially cylindrical body configured to be received within the intermediate chamber.

10. The applicator assembly of claim 9, wherein the insert includes a recess formed in at least a first end thereof.

11. The applicator assembly of claim 10, wherein the recess is substantially hemispherical.

12. The applicator assembly of claim 1, wherein the first and second component channels extend into respective first and second component lumens.

13. The applicator assembly of claim 1, wherein the elongated shaft is composed of silicone.

14. The applicator assembly of claim 1, wherein the elongated shaft is flexible.

15. The applicator assembly of claim 1, wherein the insert comprises silicone.

16. The applicator assembly of claim 1, wherein the tip assembly comprises silicone.

17. The applicator assembly of claim 1, wherein the tip assembly is configured to flex during operation.

18. The applicator assembly of claim 1, further including a shrink tubing about the tip assembly.

19. The applicator assembly of claim 18, wherein the shrink tubing prevents excess flexion of the tip assembly.

20. A system for mixing at least a first and second component, the system comprising:

at least a first and a second source of component;

a manifold configured for operable engagement with the at least first and second sources of component, the manifold including at least a first and a second component channel therethrough;

an elongated shaft extending distally from the manifold, the elongated shaft including at least a first and a second component lumen extending the length thereof, the at least first and second component lumens in fluid communication with the at least first and second component channels;

a tip assembly defining a first chamber, an intermediate chamber and a final chamber, wherein the first chamber is configured to receive a distal end of the elongated shaft, the second chamber is configured to receive an insert, and the final chamber is configured to receive the at least partially mixed at least first and second components prior to the mixture being ejected from an outlet defined in the distal end of the tip assembly.
