  • Patent number: 6489172
    Abstract: A saliva sampling device includes an expresser cup, an absorbent foam swab capable of absorbing a fluid specimen, and a flexible tether affixed to the foam swab. The foam swab is used to collect a sample of a fluid specimen such as saliva, and the tether is adapted to enable a user to sanitarily draw the saturated foam swab into the expresser cup in which the foam swab becomes compressed: and the absorbed fluid is expressed therefrom in a drop by drop fashion. The device also may include a platform having a reagent strip for absorbing the expressed fluid to reveal test results. The device may also include a divider for separating the expressed fluid into two or more aliquots prior to the testing thereof such that one of the aliquots may be used for confirmation or later testing of the fluid. In one embodiment, the expresser cup includes a conical cross section to effect gradual compression of the foam swab.

  • Patent number: 6468474
    Abstract: A saliva testing and confirmation device generally includes an expresser cup adapted to receive and compress a foam collection swab pressed into the cup. The swab includes a sponge or foam portion capable of absorbing a fluid specimen such as saliva, and a generally rigid handle for facilitating manipulation thereof. The device also includes a testing and confirmation platform integral with the expresser cup. A channel or groove in the cup is provided for directing a flow of expressed fluid from the expresser into both a test well and a confirmation well. A lateral flow reagent test strip, in fluid communication with the test well may be encased in the platform and partially revealed for analysis of test results. The confirmation well includes a fluid tight cap having a tamper evident seal.
