Toothbrush system with a three-dimensional brushing action and fluid irrigation
First Claim
1. A toothbrush system for cleansing tooth surfaces and under a user'"'"'s gum line, comprising:
- (a) a handle member having an internal chamber containing a fluid;
(b) a head member secured to said handle member, a fluid conduit extending within said head member in fluid communication with said internal chamber of said handle member;
(c) a head unit secured to an end of said head member located remote from said handle member, said head unit having a central axis, said head unit including;
at least one bristle platform, bristles located on said at least one bristle platform in circumferential disposition with said central axis of said head unit, and a hydraulically biased irrigating member in fluid communication with said internal chamber of said handle member through said fluid conduit, said irrigating member having an irrigator nozzle reversibly reciprocatable along said central axis of said head unit between a retracted and an extended position of said irrigator nozzle, said irrigator nozzle releasing said fluid when said irrigator nozzle is in said extended position.

Abstract
A toothbrush system using a combination of mechanical force and fluid dynamics to increase the efficiency of plaque removal from the teeth and gums. The toothbrush includes a head unit with an irrigator nozzle and a hydraulically actuated and continuously variable bristle platform which negotiates the complex surface geometry found in the mouth of a user. The irrigation nozzle is powered by the pulsing of an anti-microbial irrigant which gives the toothbrush head unit the distinguishing ability of being able to “feel” the contour of the teeth and to “find” the spaces between them. Once the sensing irrigator nozzle finds the spaces between the teeth, it extends into the area, and releases the anti-microbial liquid directly into the space. The configured bristle tufts of the head unit automatically adjust their position for cleaning under the gum line, between the teeth, as well as flat surfaces.
