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, at least one irrigation port, and at least one suction port;
a post coupled to the head;
an injection port positioned on the post and in fluid communication with the at least one irrigation port; and
a handle coupled to the post, the handle including:
a ventilation port in fluid communication with the at least one suction port and configured to be coupled to the suction device, the ventilation port permitting suction from the suction device to the at least one suction port,
a user interface configured to receive feedback from the operator, and
a controller 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.

2. The electric toothbrush of claim 1 , wherein the user interface includes the ventilation port, which is configured to control permitting suction from the suction device to the at least one suction port based on the operator covering and releasing the ventilation port.

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

4. The electric toothbrush of claim 1 , wherein the at least one irrigation port is interspersed among the plurality of bristles.

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

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

7. The electric toothbrush of claim 1 , wherein the head is removably coupled to the handle.

8. The electric toothbrush of claim 1 wherein the post is removably coupled to the handle.

9. The electric toothbrush of claim 8 , wherein the head and the post are constructed of a pliable material.

10. The electric toothbrush of claim 1 , wherein the head is constructed of a pliable material.

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

12. The electric toothbrush of claim 1 , wherein the ventilation port and the user interface are positioned relative to each other on the handle to accommodate single-handed operation of the electric toothbrush.

13. The electric toothbrush of claim 1 , wherein the a plurality of bristles and the at least one irrigation port are located along a front surface of the head and the at least one suction port is located along a side surface of the head.

14. The electric toothbrush of claim 13 and further comprising a tongue scraper located along a rear surface of the head.

15. The electric toothbrush of claim 1 , 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 bristles when the internal timer is started and to stop actuation when the internal timer is expired.

16. The electric toothbrush of claim 1 , wherein the handle includes a suction connection and internal tubing routed from the suction connection through the handle to the at least one suction port, wherein the ventilation port extends through the handle and into the internal tubing.

17. The electric toothbrush of claim 16 , wherein the suction connection is configured to be removably coupled to the suction device through suction tubing.

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

19. The electric toothbrush of claim 1 , wherein the user interface includes an on/off switch.
