  • Publication number: 20200393454
    Abstract: A fluid specimen collection, storage, transport, and testing cup contains a removable chromatographic strip-carrying cartridge and an axially moveable liquid specimen preserving caddy which moves between a first, pre-test position and a second, post-test position. During which a caddy drain is temporarily opened allowing an amount of liquid specimen deposited in the caddy to flow into the cup and contact the strips. Once in the second position, the drain is sealed for later confirmatory testing. The caddy is moved between the two positions by screwing a threaded lid more tightly onto the top opening of the cup. The axial range of the screw is limited by a removable obstruction collar. The caddy can include a liquid specimen containing chamber having a lower opening sealed by a frangible barrier.

  • Patent number: 9687844
    Abstract: A fluid specimen collection, storage, transport, and testing cup contains a chromatographic strip-carrying caddy which moves between an initial position allowing a deposited liquid specimen to contact the test strips, and a second, sealed position where the strips are hermetically isolated from a remainder portion of the specimen stored for later confirmatory testing. The caddy is moved between the two positions by screwing a threaded lid onto the top opening of the cup. The axial range of the screw is limited by a removable obstruction collar. The caddy can include a liquid specimen containing chamber having a lower opening sealed by a frangible barrier. The strips can be loaded in a cartridge mountable to the caddy. An adulteration panel having a transparent adhesive backed fronting can secure adulteration patches to the caddy.
