  • Patent number: 6833111
    Abstract: A multiple analyte assaying device includes a casing having a pocket portion adapted to capture or contain a predetermined volume of fluid specimen to be assayed. Disposed within the casing is a sample receiving pad and one or more reagent test strips. The pocket portion of the casing includes a feed element having multiple feed inlets, or alternatively, a single feed slot. The feed element provides pressure against the sample receiving pad. The pressure against the pad and a small size of the inlet or inlets are effective in controlling a rate of fluid release of the specimen to the sample receiving pad. The casing includes observation windows or alternatively a clear plastic view area for enabling observation of reagent zones of the test strips. The device is structured and adapted to enable a technician to capture the appropriate volume of fluid specimen in the pocket portion by submerging or dipping a portion of the device into a fluid-filled collection container for a brief period of time.
    Type: Grant

  • 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.
