AI Technical Summary

Benefits of technology

This design ensures all test strips are effectively contacted by the bodily fluid, reducing operator error and providing valid results on a single face, while the pressurization enhances capillary action for accurate analysis.

Problems solved by technology

One problem with the prior art arrangement of having a plurality of test strips arrayed on several sides of a test container is that the arrangement is prone to operator error.
While holding the device, there is a tendency to tilt the proximal face of the device backward for easier reading.
Unfortunately, this can cause the bodily fluid under test to pool at the bottom of the distal face of the testing device, thus starving the test strips that are disposed on the proximal face.
The result is an invalid test for the constituents represented by the test strips on the proximal face.

Embodiment Construction

[0026]Referring to FIG. 1, a testing assembly 20 for screening bodily fluids for the presence of certain constituents is depicted in an embodiment of the invention. The screening device includes a container or cup 22, a test strip and sampling stem holder 24 (hereinafter “holder 24”), a three-dimensional gasket 26 and a sampling stem 28.

[0027]Referring to FIGS. 2 and 3, the cup 22 is depicted in isolation in an embodiment of the invention. The cup 22 includes a plurality of sides 32 and 34 that extend upward from a containment bottom 38 to form a continuous upper edge 36, the sides 32, 34 and containment bottom 38 defining a cavity 42. The sides 32 and 34 can also extend below the containment bottom 38 to establish a base portion 40 with a lower edge 41 registers the testing assembly 20 in an upright position. A first of the sides (side 32 in FIGS. 2 and 3) can be substantially planar. In one embodiment, the containment bottom 38 defines an inclined surface 44 that intersects the pl...

Abstract

A screening device for testing bodily fluids for the presence of certain constituents. The device can include a planar front face through which all of the test strips are viewed. The device also includes an inclined surface that directs the fluid under test to test strips with more efficiency, and partitions the fluid that is directed to a given test strip to better assure that the test strip receives an adequate amount of bodily fluid for a valid analysis. In one embodiment, the device includes a three-dimensional gasket that creates a pressurized environment upon insertion of the sampling stem for improved diffusion of the bodily fluid into the test strips.

Description

RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 079,558, filed Nov. 13, 2013, which claims the benefit of U.S. Provisional Patent Application No. 61 / 725,898, filed Nov. 13, 2012, the disclosures of which are incorporated by reference herein in their entireties.FIELD OF THE INVENTION[0002]This application is directed generally to devices and methods for analysis of the presence of constituents in fluids, and more specifically to devices and methods for analysis of the presence of constituents in bodily fluids for drug test screening.BACKGROUND OF THE INVENTION[0003]Various drug screening devices are known for testing a sample of bodily fluids for the presence of certain constituents. These devices typically include a container for receiving a bodily fluid from a delivery device, and a plurality of reagent test strips arranged to contact the bodily fluid, with each test strip being sensitive to a particular constituent of interest.
