1. A saliva sampling device comprising:

  • a. a first hollow, cylindrical member having a innerly overhanging peripheral circular rim with a curved notch therein;

    b. a second hollow, cylindrical member having a top flat member which has a drain with a seal-breaking member disposed therein, said first hollow, cylindrical member being coupled to said second hollow, cylindrical member whereby said curved notch in said innerly overhanging peripheral circular rim is aligned with said seal-breaking member in said drain;

    c. a rotatable cylinder, which has a first bore and a plurality of second bores, disposed in and rotatively coupled to said first hollow, cylindrical member whereby each of said first and second bores may selectively aligned with said curved notch in said innerly overhanging peripheral circular rim;

    d. a sample container having an open end and a closed end with a breakable seal being disposed at said closed end, said sample container being inserted into said first bore of said rotatable cylinder;

    e. a buffering solution contained in said sample container;

    f. a saliva collector which selectively receives a sample of saliva, said saliva collector being inserted into said sample container whereby said buffering solution and the sample of saliva mix together and when said curved notch is aligned with said first bore said sample container is pressed downward so that said seal-breaking member breaks said breakable seal in order for said mixture of said buffering solution and the sample of saliva to flow into said drain in said top flat member of said second hollow, cylindrical member;

    g. a plurality of reagent containers each of which has an open end, which is closed by a cap, and a closed end with a breakable seal being disposed at said closed end and each of which contains a pre-selected reagent solution and is inserted into one of said second bores of said rotatable cylinder whereby when said curved notch is selectively aligned with each of said second bores so that one of said reagent containers is selectively pressed downward so that said seal-breaking member breaks said breakable seal thereof in order for said pre-selected reagent solution to flow into said drain in said top flat member of said second hollow, cylindrical member and mix together with said mixture of said buffering solution and the sample of saliva.
