Abstract

A dental hygiene system provided with interchangeable dental heads permits power-enhanced brushing and concurrent fluid irrigation to optimize a user'"'"'s personal dental hygiene efforts. The system has a handle assembly with an irrigation nozzle in close proximity to displaceable bristles driven by a battery-operated handle motor. Pumping of irrigation fluid such as an antiseptic solution into the oral cavity is also motor driven. A telescoping chamber with irrigation fluid fits on the piston-like base end of the handle and is refilled by docking the handle assembly on a complementary docking station that includes a detachable fluid reservoir, microswitch controls and a base fluid pump. Docking of the handle assembly triggers the microswitches and opens a check valve in the bottom of the handle chamber, which activates the flow of fluid from the reservoir into the chamber. An optional fiberoptic subassembly illuminates the oral cavity.

Claims

1. A dental hygiene device comprising:

a. a dental hygiene head with a plurality of displaceable bristles secured thereto and extending therefrom adapted for brushing a dental surface, said dental hygiene head further including an irrigation mechanism for irrigating said dental surface with a fluid, said irrigating mechanism being fixedly located substantially adjacent to said displaceable bristles;

b. a longitudinally extended handle housing connected to said dental hygiene head and adapted to be held by an operator, said handle housing having a control mechanism mounted thereon for activation and deactivation of said dental hygiene device;

c. at least one handle pump for displacing said fluid, said at least one handle pump mounted in said handle housing and in fluid communication with said irrigating mechanism through a first fluid conduit;

d. a telescoping handle chamber housing slidingly engageable with said handle housing and telescopingly received therein at a piston end of said handle housing opposite said dental hygiene head and in fluid communication with said handle pump by a second fluid conduit, said dental hygiene head, said handle housing and said telescoping handle chamber housing defining a handle assembly;

e. a fluid reservoir in detachable fluid communication with a docking base member, said docking base member in detachable fluid communication with said telescoping handle chamber housing, said docking base member adapted to receivingly detachably dock said handle assembly;

wherein a filling of said telescoping handle chamber with said fluid in the fluid reservoir is controlled by inserting said telescoping handle chamber housing on said docking base member for passage of fluid from said fluid reservoir into said telescoping handle chamber housing.

2. The dental hygiene device as recited in claim 1 including a bristle actuation mechanism for displacing said bristles in an oscillating displacement.

3. The dental hygiene device as recited in claim 1 including a bristle activation mechanism for displacing said bristles in a rotatable displacement.

4. The dental hygiene device as recited in claim 1, wherein said irrigation mechanism includes at least one fluid outlet nozzle in said dental hygiene head in fluid communication with said first fluid conduit.

5. The dental hygiene device as recited in claim 4, further comprising an illumination mechanism for lighting said dental surface.

6. The dental hygiene device as recited in claim 5 wherein said irrigation mechanism further includes a fluid modulation mechanism for modulating a flow of said fluid external said dental hygiene head.

7. The dental hygiene device as recited in claim 5, wherein said illumination mechanism includes a light emitting device fixedly located interior said handle housing and in optical communication with a fiberoptic bundle extending axially within said handle housing and terminating in said dental hygiene head adjacent said irrigation mechanism.

8. The dental hygiene device as recited in claim 7, wherein said first fluid conduit includes said fiberoptic bundle.

9. The dental hygiene device as recited in claim 1, wherein said dental surface is a surface chosen from the group consisting of gingival, sub-gingival, periodontal, dental, periosteal, buccal, lingual, mucosal, and any combination therein.

10. The dental hygiene device as recited in claim 1, wherein said fluid is chosen from the group consisting of antiseptic, antibiotic, anti-inflammatory, analgesic, anesthetic, antiviral, antifungal, anti-neoplastic fluids or any combination therein, said fluid being in a liquid or a gel or a gaseous condition.

11. The dental hygiene device as recited in claim 1, wherein said handle chamber has a fluid capacity in a range of about 0 to about 100 cc'"'"'s, corresponding respectively to an empty chamber condition and a full chamber condition.

12. The dental hygiene device as recited in claim 1, further comprising at least one motor mounted in said handle housing for oscillating and rotating said plurality of bristles and for causing said handle pump to displace said fluid.

13. The dental hygiene device as recited in claim 1 including a check valve mechanism mounted in the telescoping handle chamber housing in fluid communication with a chamber formed within the telescoping handle chamber housing and said fluid reservoir.

14. The dental hygiene device as recited in claim 13 wherein said check valve mechanism includes a ball valve mounted within a recess formed in a base surface of said telescoping handle chamber, and a complementary protrusion formed in said docking base member for displacement of said ball valve when said handle assembly is docked on said base unit.

15. The dental hygiene device as recited in claim 14 where said ball valve includes a ball member mounted within a ball housing, said ball member being biased by a spring member for terminating fluid communication between said fluid reservoir and said telescoping handle chamber housing when said telescoping handle chamber housing is removed from said docking base member and providing fluid communication between said fluid reservoir and a chamber formed within said telescoping handle chamber housing when said telescoping handle chamber housing is mounted on said docking base member.

16. The dental hygiene device as recited in claim 1 further comprising a chamber status signal light member mounted in said telescoping handle chamber.

17. The dental hygiene device as recited in claim 16 further comprising a reservoir status signal light member mounted in said fluid reservoir.

18. The dental hygiene device as recited in claim 1 including a base pump in fluid communication with said fluid reservoir and said telescoping handle chamber housing for charging said handle chamber housing with said fluid when said telescoping handle chamber housing is mounted on said docking base member.

19. The dental hygiene device as recited in claim 18 including a pressure limit cut-off switch for terminating operation of said base pump responsive to a predetermined pressure sensed in said telescoping chamber housing.
