Fluid-specimen collecting and testing device and method for recording chromatographic assay test results
A fluid specimen testing device having a removable lid which carries at least one testing strip behind a transparent top viewing window. Testing is initiated by tilting the device into a stable sideways orientation to allow the specimen to contact the sampling pad portion of the strip. The device is adapted to provide stability in the upright, tilted and inverted orientations. A roll-inhibiting feature also acts as an indicator for proper roll positioning in the tilted configuration. The strips are also oriented in the lid so that they are substantially vertical when the device is in the tilted position thereby enhancing a condition for proper capillarity. The strip is carried close to the upper surface which allows it to be copied on a flat glass copier providing for more objective recordation of the test results.
1. A device for collecting specimens and for testing said specimens when said device is placed in a particular, optimum test position and orientation, said device comprising:
a receptacle having an inner chamber and a top aperture;
a lid shaped and dimensioned to seal said aperture and having at least one pocket shaped and dimensioned for mounting an oblong test indicator strip;
said lid having a position stabilizer consisting essentially of a disk-shaped top portion, a substantially cylindrical, flanged sidewall, and a single pair of ears extending radially from said side wall and being positioned to stabilize said receptacle exclusively in said position and orientation;
wherein said ears form readily perceivable means for distinctively indicating said test orientation, and for placing said pocket and strip in a vertical position.
2. The device of claim 1 , wherein said lid has at least three upper portions spaced apart and lying substantially within a first plane wherein said portions are sized and positioned to create bearing points in which to stabilize said device in an inverted orientation.
3. The device of claim 2 , wherein said upper portions are formed into a substantially flat upper surface of said lid.
4. The device of claim 2 , wherein said test strip is mounted substantially parallel to and proximal to said first plane.
5. The device of claim 4 , wherein a shortest distance between said strip and said first plane is between about 1 millimeter and about 5 millimeters.
6. The device of claim 1 , wherein said pocket has a closed end and an opposite end terminating in an aperture in communication with said chamber, said aperture being sized and shaped to encircle a first end of said strip.
7. The device of claim 6 , wherein a substantially transparent, fluid-impermeable window separates said pocket from an upper surface of said lid.
8. The device of claim 1 , wherein an outer surface of said window is treated with a substantially transparent anti-reflective coating.
9. The device of claim 6 , wherein said pocket is formed by a channel created in an under-surface of said lid and partially covered by a layer of fluid impermeable sheet material having a chemically inert lower surface and an adhesive upper surface.
10. The device of claim 9 , wherein said sheet material comprises a layer selected from the group consisting of vinyl, foil, plastic, Teflon and other optically transparent material.
11. The device of claim 9 , wherein said sheet material is bonded to said lid by a sonic weld or glue.
12. The device of claim 1 , wherein said device further comprises means for stable orientation of said device in an upright, a titled, and an inverted position.
