and means for providing an effective seal of the device within the oral cavity. ## Claims ### Claim 1 A mouthpiece for directing a liquid onto a plurality of surfaces of an oral cavity of a mammal, said mouthpiece comprising: a chamber for maintaining said liquid proximate said plurality of surfaces, said chamber defined by front and rear inner walls and a base inner wall of said mouthpiece, said base wall extending between said front and rear inner walls, said front and rear inner walls comprising a plurality of openings, a first manifold for containing a first portion of said liquid and providing said first portion to said chamber through said openings of said front inner wall, a second manifold for containing a second portion of said liquid and providing said second portion to said chamber through said openings of said rear inner wall, a first port for conveying said first portion of liquid to and from said first manifold, a second port for conveying said second portion of liquid to and from said second manifold; wherein said mouthpiece comprises only two ports, said first and second ports, for conveying liquid to and from said mouthpiece. ### Claim 2 (depends on 1) The mouthpiece of claim 1 further comprising means for attaching said mouthpiece to means for providing said liquid to said mouthpiece. ### Claim 3 (depends on 2) The mouthpiece of claim 2 wherein said means for attaching comprises a quick disconnect structure for attaching said mouthpiece to said means for providing said liquid to said mouthpiece. ### Claim 4 (depends on 2) The mouthpiece of claim 2 wherein said means for attaching comprises a support plate fixedly attached to the front of said mouthpiece and having said first and second ports extending there through, said support plate comprising a structure for attaching said mouthpiece to said means for providing liquid to said mouthpiece. ### Claim 5 (depends on 1) The mouthpiece of claim 1 comprising a plurality of front lumens connected by said first manifold and a plurality of rear lumens connected by said second manifold. ### Claim 6 (depends on 5) The mouthpiece of claim 5 wherein said plurality of front lumens are connected along their length to form at least one lumen hinge section. ### Claim 7 (depends on 5) The mouthpiece of claim 5 comprising from 3 to 7 front lumens that are connected along their length to form a plurality of lumen hinge sections. ### Claim 8 (depends on 5) The mouthpiece of claim 5 wherein said plurality of rear lumens are also connected along their length to form at least one lumen hinge section. ### Claim 9 A mouthpiece for directing a liquid onto a plurality of surfaces of an oral cavity of a mammal, said mouthpiece comprising: a chamber for maintaining said liquid proximate said plurality of surfaces, said chamber defined by front and rear inner walls and a base inner wall of said mouthpiece, said base wall extending between said front and rear inner walls, said front and rear inner walls comprising a plurality of openings, a first manifold for containing a first portion of said liquid and providing said first portion to said chamber through said openings of said front inner wall, a second manifold for containing a second portion of said liquid and providing said second portion to said chamber through said openings of said rear inner wall, a first port for conveying said first portion of liquid to and from said first manifold; a second port for conveying said second portion of liquid to and from said second manifold; a plurality of front lumens connected by said first manifold and a plurality of rear lumens connected by said second manifold. ### Claim 10 (depends on 9) The mouthpiece of claim 9 wherein said plurality of front lumens are connected along their length to form at least one lumen hinge section. ### Claim 11 (depends on 9) The mouthpiece of claim 9 comprising from 3 to 7 front lumens that are connected along their length to form a plurality of lumen hinge sections. ### Claim 12 (depends on 9) The mouthpiece of claim 9 wherein said plurality of rear lumens are also connected along their length to form at least one lumen hinge section.
