Abstract

Claims (25)

1. An oral insert, comprising:

a plurality of fluid nozzles; and

a plurality of manifolds, wherein each of the manifolds is associated with a corresponding subset of the plurality of fluid nozzles; and

an attachment mechanism configured to be releasably attached with a handle, wherein the attachment mechanism includes a manifold connector having a plurality of manifold openings arranged in a circle, wherein each of the plurality of manifold openings is associated with one of the plurality of manifolds.

2. The oral insert of claim 1 , wherein a number of the plurality of manifold openings is eight.

3. The oral insert of claim 1 , wherein a number of the plurality of manifolds is eight.

4. The oral insert of claim 1 , wherein the attachment mechanism is a female portion of an oral insert-handle attachment mechanism.

5. The oral insert of claim 4 , wherein the attachment mechanism includes a collar.

6. The oral insert of claim 5 , wherein the handle comprises a male portion and configured to be attached to the oral insert-handle attachment mechanism.

7. The oral insert of claim 6 , wherein the attachment mechanism is releasably attached with the handle by inserting the male portion of the handle into the female portion of the attachment mechanism and rotating the collar.

8. The oral insert of claim 1 , further comprising:

an upper trough configured to engage with a top set of teeth associated with a user; and

a lower trough configured to engage with a bottom set of teeth associated with the user.

9. The oral insert of claim 8 , further comprising an effluence conduit located in between the upper trough and the lower trough.

10. The oral insert of claim 9 , wherein the effluence conduit includes a central channel that terminates at an anterior opening of the oral insert.

11. The oral insert of claim 10 , wherein the effluence conduit includes a first posterior opening located on a first interior surface of the oral insert.

12. The oral insert of claim 11 , wherein the effluence conduit includes a second posterior opening located on a second interior surface of the oral insert.

13. The oral insert of claim 9 , wherein a height of the effluence conduit increases from a posterior region of the oral insert to an anterior region of the oral insert.

14. The oral insert of claim 9 , wherein the effluence conduit is U-shaped.

15. The oral insert of claim 8 , wherein a first subset of the plurality of fluid nozzles is located in the upper trough and a second subset of the plurality of fluid nozzles is located in the lower trough.

16. The oral insert of claim 1 , wherein each of the plurality of manifold openings is circular.

17. The oral insert of claim 1 , wherein the plurality of manifold openings are radially distributed about a center of the manifold connector.

18. The oral insert of claim 1 , wherein an angular spacing between a first manifold opening and a second manifold opening is equal to an angular spacing between a second manifold opening and a third manifold opening.

19. The oral insert of claim 1 , wherein an angular spacing between the plurality of manifold openings is determined at least in part on a number and size of each of the plurality of manifold openings.

20. The oral insert of claim 1 , wherein the oral insert is an elastomeric substrate.
