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.
Claims20
A device for testing saliva, the device comprising:
- a cup comprising an outer planar forward wall connecting to an outer curved rearward wall providing a D-shaped outer perimeter of the device when viewed from below and above, the outer planar forward wall providing the straight portion of the “D” and the outer curved rearward wall providing the remainder of the “D”, the cup having a lower edge that registers the cup in an upright position, a single inclined plate traversing continuously upwardly and rearwardly between the planar forward wall and the curved rearward wall, the inclined plate having a lowermost portion of the plate proximate the planar front wall and an uppermost portion of the inclined plate exclusively at the rearward wall and the inclined plate defining a cavity with a single lowermost extremity of the cavity positioned at the planar forward wall;
- a holder including a cap portion;
- the cap portion positioned at a top portion of the cup, the cap portion having a D-shaped outer perimeter when viewed from above, the D-shaped outer perimeter providing an outermost periphery of the device when viewed from above;
- wherein the cap portion comprising a through passage structure comprising a hollow tube positioned below the cap portion, the hollow tube extending toward the inclined plate;
- and wherein the holder includes a planar face that extends downward from the cap portion into the cup and the planar face comprises a plurality of parallel ribs that define a plurality of elongate channels for engaging a test strip;
- a sampling stem having a proximal portion and a distal portion, the distal portion including a sampling swab for absorbing saliva, the sampling stem insertable through the cap into the through passage structure whereby the swab engages an upwardly facing surface for compressing the sampling swab at the upwardly facing surface to squeeze saliva in the sampling swab out of the sampling swab, the upwardly facing surface at a location forward of and below the uppermost portion of the inclined plate.

A device for testing saliva, the device comprising:
- a cup comprising a planar forward wall connecting to a curved rearward wall defining a D-shaped outer wall perimeter when viewed from above and below, a single inclined plate traversing and extending upwardly and rearwardly between the planar forward wall and connecting to the curved rearward wall at an uppermost portion of the inclined plate, the inclined plate having a planar upper surface and an inclination extending the entire distance from the forward wall to the rearward wall, the forward wall, the curved rearward wall, and the inclined plate defining a single cavity having a single lowermost extremity along the planar front wall, the inclined plate and planar forward wall defining an acute angle, wherein the forward wall has a side to side width and the forward side to side width is a maximum side to side width of the cup;
- a holder having a planar face adjacent the planar forward wall, comprising a cap portion positioned at the opening of the cup, the cap portion having through passage structure comprising a hollow tube, the hollow tube extending toward the inclined plate;
- the planar face of the holder positioned in the cavity adjacent the planar forward wall of said cup, a plurality of test strips positioned between the planar face and the planar forward wall;
- wherein the cap portion is positioned at a top portion of the cup, the cap portion has a D-shaped outer perimeter when viewed from above, and the D-shaped outer perimeter provides an outer most periphery of the device when viewed from above;
- a sampling stem having a proximal portion and a distal portion, the distal portion including a sampling swab for absorbing saliva, the sampling stem insertable into the through passage structure of the cup for squeezing out the saliva at a location below the uppermost portion of the inclined plate.
