Abstract

A toothbrush for use by an operator and capable of being connected to a suction device and a syringe. The toothbrush includes a head, a handle, and a suction assembly. The head includes a plurality of bristles and an irrigation port configured to be in fluid communication with the syringe. The handle is coupled to the head and includes a user interface and a controller configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to feedback from the operator through the user interface. The suction assembly is coupled to one of the head and the handle and configured to be coupled to the suction device. The suction assembly includes a suction tip that is movable relative to the head.

First claim

The invention claimed is:

1. A toothbrush for use by an operator and capable of being connected to a suction device, the toothbrush comprising:
a head;
a handle coupled to the head;
a suction assembly coupled to one of the head and the handle and configured to be coupled to the suction device, the suction assembly moveable along a length of one of the head and the handle and including a suction tube,
wherein the handle includes a track, and the suction assembly includes a slider that is moveable back and forth along the track, the slider configured to receive the suction tube; and
a light source configured to direct light away from the handle toward the head,
wherein the light source includes at least one light emitting diode and a light pipe configured to direct light from the at least one light emitting diode toward the head, and
wherein the light pipe extends around over half of an outer circumference of the handle.

2. The toothbrush of claim 1 , wherein the head includes a plurality of bristles and an irrigation port configured to be in fluid communication with a syringe.

3. The toothbrush of claim 2 , wherein the head includes a post coupled to the handle, and a tip coupled to the post, the tip including the plurality of bristles.

4. The toothbrush of claim 3 , wherein the irrigation port is located at one of a top end of the post, and an intersection between the tip and the post.

5. The toothbrush of claim 2 , wherein the handle includes an irrigation compartment in fluid communication with the irrigation port and sized to receive a portion of the syringe.

6. The toothbrush of claim 5 , wherein the irrigation compartment includes a lower opening and an upper opening, the lower opening located at a bottom of the handle opposite the head and configured to receive the syringe, and the upper opening located adjacent to an internal compartment of the head.

7. The toothbrush of claim 5 , wherein the handle includes a dry compartment substantially sealed from the irrigation compartment, a controller being housed in the dry compartment.

8. The toothbrush of claim 7 , wherein the dry compartment includes a motor in communication with the controller, the motor operably coupled to the plurality of bristles to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles.

9. The toothbrush of claim 2 and further comprising a controller configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to feedback from the operator through a user interface of the handle.

10. The toothbrush of claim 1 , wherein
the suction assembly includes:
a suction tip positioned at a first end of the suction tube, and
wherein the slider is configured to be coupled to a second end of the suction tube and the suction device.

11. The toothbrush of claim 10 , wherein the slider includes a tube portion configured to be coupled to the suction tube and the suction device, and a ventilation port in fluid communication with the tube portion, the ventilation port permitting and relieving suction from the suction device to the suction tip based on feedback from the operator.

12. The toothbrush of claim 10 , wherein the head includes a guide configured to engage the suction tube.

13. The toothbrush of claim 10 , wherein the suction assembly is movable between a non-use position where the suction tip is positioned between the handle and a tip of the head, and a suction use position where the suction tip is positioned past the tip of the head.

14. The toothbrush of claim 1 , wherein the track extends from a first location at a top end of the handle to a second location along a length of the handle.

15. The toothbrush of claim 1 , wherein the head includes a plurality of bristles, the handle includes a user interface and a controller configured to actuate at least one of rotation, oscillation, and vibration of the plurality of bristles in response to feedback from the operator through the user interface, and the controller is configured to operate the light source when actuating at least one of rotation, oscillation, and vibration of the plurality of bristles.

16. A toothbrush for use by an operator and capable of being connected to a suction device, the toothbrush comprising:
a head;
a handle coupled to the head; and
a suction assembly coupled to one of the head and the handle and configured to be coupled to the suction device, the suction assembly moveable along a length of one of the head and the handle,
wherein the handle includes a track, and the suction assembly includes a slider that is moveable back and forth along the track,
wherein the suction assembly includes a suction tube, a suction tip positioned at a first end of the suction tube, and wherein the slider is configured to be coupled to a second end of the suction tube and the suction device,
wherein the head includes a guide configured to engage the suction tube,
wherein the guide is removably coupled to a post of the head.

17. A toothbrush for use by an operator and capable of being connected to a suction device, the toothbrush comprising:
a head, wherein the head includes a plurality of bristles and an irrigation port configured to be in fluid communication with a syringe;
a handle coupled to the head; and
a suction assembly coupled to one of the head and the handle and configured to be coupled to the suction device, the suction assembly moveable along a length of one of the head and the handle,
wherein the handle includes a track, and the suction assembly includes a slider that is moveable back and forth along the track,
wherein the handle includes an irrigation compartment in fluid communication with the irrigation port and sized to receive a portion of the syringe,
wherein the handle includes a window in communication with the irrigation compartment and in a location to enable the operator to view a portion of the syringe inside the irrigation compartment.
