Abstract

Claims (19)

1. A system, comprising:

an oral insert that includes a plurality of manifolds and a plurality of fluid nozzles, wherein the oral insert includes a fluid inlet port configured to receive fluid from a fluid source and an effluence conduit configured to enable the fluid to exit the oral insert, wherein the effluence conduit includes a central port configured to drain the fluid from a mouth of a user, a first posterior opening located on a first lingual surface of the oral insert and a second posterior opening located on a second lingual surface of the oral insert, wherein the first posterior opening is coupled to a first lateral channel and the second posterior opening is coupled to a second lateral channel, wherein the first lateral channel and the second lateral channel are coupled to the central port, wherein the first posterior opening and the second posterior opening are configured to receive the fluid from a posterior oral cavity region of the user, wherein the central port terminates at a single anterior opening located at a front portion of the oral insert, wherein the oral insert is customized to a user and includes a trough having one or more alignment features located within the trough to help seat some teeth of the user within the trough; and

a manifold switch coupled to the plurality of manifolds, wherein the manifold switch is configured to select which of the plurality of manifolds is to receive the fluid from the fluid source via a manifold connector located at a bottom portion of the oral insert.

2. The system of claim 1 , wherein a first manifold of the plurality of manifolds includes one or more pressure ports.

3. The system of claim 2 , wherein the first manifold includes a first number of fluid nozzles and a second manifold of the plurality of manifolds includes a second number of fluid nozzles, wherein the first number and the second number are different.

4. The system of claim 3 , wherein a first flow rate of the fluid exiting from the fluid nozzles of the first manifold is within a predetermined tolerance of a second flow rate of the fluid exiting from the fluid nozzles of the second manifold.

5. The system of claim 4 , wherein the first flow rate of the fluid exiting from the fluid nozzles of the first manifold is based on a location and size of the one or more pressure ports.

6. The system of claim 1 , wherein the manifold switch is configured to sequentially output the fluid to the plurality of manifolds.

7. The system of claim 6 , wherein the fluid is sequentially outputted to the plurality of manifolds in an overlapping manner.

8. The system of claim 1 , wherein the manifold switch is configured to switch between the plurality of manifolds at a rate of 8 Hz to 30 Hz.

9. The system of claim 1 , wherein the manifold switch is configured to provide a pulsatile flow of the fluid.

10. The system of claim 1 , wherein a location of the one or more alignment features is based on an undercut region adapted to be associated with an oral anatomy of the user.

11. The system of claim 1 , wherein the plurality of manifolds have a continuous taper.

12. The system of claim 1 , wherein the central port is configured to have a cross-section area that causes the fluid exiting the oral insert to have a particular pressure.

13. The system of claim 12 , wherein the particular pressure is 0.05 psi within a threshold amount.

14. The system of claim 1 , wherein the plurality of fluid nozzles are V-shaped.

15. The system of claim 14 , wherein a corresponding angle associated with each of the plurality of fluid nozzles is specific to the user.

16. The system of claim 1 , further comprising a handle that includes the manifold switch.

17. The system of claim 16 , wherein the handle further includes a pump that is configured to provide a particular flow rate of fluid having a particular amount of pressure.
