Abstract
A screening device for testing saliva for the presence of certain constituents. The device has a D-shaped profile when viewed from above and includes a first wall with planar front face through which all of the test strips are viewed and a curved rear second wall. The device also includes a floor surface with an uppermost portion extending from the rear wall to a lowermost portion at the first wall such that saliva squeezed from a sampler at a location between the upper most portion and the lowermost portion flows downwardly to the test strips.
Claims18
A device for testing a liquid sample, the device comprising:
- a cup defining an interior cavity, the cup having a planar forward wall and a rearward wall;
- a holder having an insertion portion positioned in the cup and a cap portion;
- the cap portion of the holder defining an access port, and the insertion portion has a through passage structure extending from a bottom of the cap portion into the interior cavity of the cup, the through passage structure defining a tubular through passage aligned with the access port;
- the holder further including a female threaded structure proximate the access port of the cap portion;
- a swab compression structure aligned with the tubular through passage;
- a plurality of test strips arranged in parallel to each other adjacent the planar forward wall of the cup;
- and
- a sampling stem insertable through the access port of the cap, the sampling stem having a sampling swab at a distal portion thereof and male threaded portion at a proximal portion thereof,
- wherein the male threaded portion of the sampling stem engages the female threaded portion of the holder such that rotation of the sampling stem in one rotational direction causes axial movement of the sampling stem such that the sampling swab will be compressed against the swab compression structure.

- and
- a sampling stem insertable through the access port of the cap, the sampling stem having a sampling swab at a distal portion thereof and male threaded portion at a proximal portion thereof, the distal portion of the sampling stem having a collar that provides a seal with an inner surface of the through passage structure,
- wherein the male threaded portion of the sampling stem engages the female threaded portion of the holder such that rotation of the sampling stem in one rotational direction causes axial movement of the sampling stem such that the sampling swab will be compressed against the swab compression structure.

- and
- the holder and sampling stem together having a ratchet and pawl mechanism operative to lock the sampling stem against backward rotation relative to the holder,
- wherein the ratchet and pawl mechanism comprises at least one pawl adjacent to the knob, the at least one pawl being situated between the knob and the male threaded portion along an axis of the sampling stem and is received in the access port during tightening.
