Abstract

An electric toothbrush for use by an operator and capable of being connected to a suction device. The electric toothbrush includes a head with a plurality of bristles, at least one irrigation port, and at least one suction port, and an injection port in fluid communication with the at least one irrigation port. The electric toothbrush also includes a handle with a ventilation port in fluid communication with the at least one suction port, a user interface, and a controller. The ventilation port permits suction from the suction device to the at least one suction port and the controller is configured to actuate at least one of rotation, oscillation, and vibration of the bristles for a preset time period in response to a predetermined feedback from the operator through the user interface.

First claim

The invention claimed is:

1. An electric toothbrush for use by an operator and capable of being connected to a suction device, the electric toothbrush comprising:
a head including a plurality of bristles;
an irrigation port;
an injection port in fluid communication with the irrigation port;
a suction port;
a suction connection in fluid communication with the suction port and configured to be coupled to the suction device;
a ventilation port in fluid communication with the suction port and the suction connection, the ventilation port permitting suction from the suction device to the suction port; and
a handle coupled to the head and including a user interface configured to receive feedback from the operator, the handle configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to a predetermined feedback from the operator through the user interface.

2. The electric toothbrush of claim 1 , wherein the handle includes a controller configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to the predetermined feedback from the operator through the user interface.

3. The electric toothbrush of claim 2 , wherein the controller is further configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles for a preset time period in response to the predetermined feedback from the operator through the user interface.

4. The electric toothbrush of claim 3 , wherein the controller includes an internal timer configured to start in response to the predetermined feedback from the operator through the user interface and to expire when the preset time period has passed, and the controller is configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles when the internal timer is started and to stop actuation when the internal timer is expired.

5. The electric toothbrush of claim 3 , wherein the preset time period is two minutes.

6. The electric toothbrush of claim 1 , wherein the ventilation port is configured to control suction from the suction device to the suction port based on the operator covering and releasing the ventilation port; and wherein the ventilation port and the user interface are positioned relative to each other to accommodate single-handed operation of the electric toothbrush.

7. The electric toothbrush of claim 1 , wherein the irrigation port is located one of on the head and adjacent to the plurality of bristles.

8. The electric toothbrush of claim 1 and further comprising tubing routed from the suction connection to the suction port, wherein the ventilation port extends into the tubing.

9. The electric toothbrush of claim 1 , wherein the injection port is configured to be connected to a syringe.

10. The electric toothbrush of claim 9 , wherein the injection port includes a luer-lock type connection configured to be connected to a syringe.

11. The electric toothbrush of claim 1 , wherein the ventilation port is tear-drop shaped.

12. The electric toothbrush of claim 1 , wherein the user interface includes a button connected to the controller.

13. The electric toothbrush of claim 1 , wherein the head includes one of a round profile and a rectangular profile.

14. The electric toothbrush of claim 1 and further including a post that couples the head to the handle.

15. The electric toothbrush of claim 14 , wherein at least one of the ventilation port, the head, the post, and the handle are disposable.

16. The electric toothbrush of claim 14 , wherein the head and the post are constructed of a pliable material.

17. The electric toothbrush of claim 16 , wherein the injection port is in fluid communication with the irrigation port through an internal channel of the post.

18. The electric toothbrush of claim 1 , wherein the handle includes a battery compartment.

19. The electric toothbrush of claim 1 , and further comprising a tongue scraper.

20. The electric toothbrush of claim 1 , wherein the handle supports the ventilation port.
