1. An apparatus for delivering a metered stream of saliva solution, comprising:
a delivery tube for drawing a saliva solution from a saliva solution source;
a pumping and metering device connected to said delivery tube for pumping the saliva solution from the saliva solution source through said delivery tube and delivering the saliva solution to a user mouth, said delivery tube having a delivery tube upstream segment for extending from the saliva solution source to said pumping and metering device, and a delivery tube downstream segment extending from said pumping and metering device to a delivery tube free end for placement in the user mouth;
and a mouthpiece mounted to said delivery tube free end for engaging and securely retaining said delivery tube free end within the user mouth until released;
said mouthpiece comprising: a mouthpiece first panel having a first panel port, wherein said delivery tube free end passes through said first panel port and extends beyond said first panel, into the user mouth, wherein said delivery tube free end is releasably retained within said first panel port by a first tube engaging mechanism, such that said delivery tube free end can be placed within the user mouth and between upper and lower sets of user teeth, such that said retaining first panel extends radially outward from said tube between forward faces of user teeth and user lips, thereby holding said first panel and said delivery tube free end in the user mouth while obstructing movement of said delivery tube free end further into the user mouth when the user mouth is closed;
a mouthpiece second panel having a second panel port, wherein said delivery tube free end passes through said second panel port and extends beyond said second panel, into the user mouth such that said second panel is spaced rearwardly of said first panel along said delivery tube to receive between said first panel and said second panel the user teeth, wherein said delivery tube free end is releasably retained within said second panel port by a second tube engaging mechanism, such that said delivery tube free end can be placed within the user mouth and between upper and lower sets of user teeth, such that said second panel extends radially outward from said tube behind rearward faces of user teeth, thereby holding said second panel and said delivery tube free end in the user mouth while obstructing movement of said delivery tube free end out of the user mouth when the user mouth is closed and when the user mouth is open, to deliver the saliva solution into the user mouth.
