Urine test device
First Claim
1. A device for collecting, testing and transporting a liquid sample of bodily fluid or the like, which device comprises:
- a container having a continuous sidewall that extends between a bottom wall and an upper opening through which a liquid specimen can be collected, said container providing a main chamber for storing such specimen and an upwardly open subchamber, and a lid for closing and sealing said upper opening to said container, said lid having a depending hollow plug section that terminates in a closed aperture, said terminal end of said plug sealingly interengaging with said subchamber to create a closed cavity of defined volume that is isolated from communication with the remainder of said chamber, whereby a liquid sample of defined volume is segregated from the remainder of such specimen within said closed cavity, so it can be tested without potentially contaminating the remainder of such specimen in said container by inserting a test element downward through said aperture at the terminus of said hollow plug section.

Abstract
A device for collecting, testing and transporting a liquid specimen of urine or the like incorporates a cup or container and a cooperating lid which becomes sealed about its upper rim when the lid is mated with the specimen-containing cup. An upwardly open subchamber of defined volume, formed in the bottom wall of the cup, is sealed by engagement with a downwardly extending hollow plug portion of the lid that has a bottom wall containing a central aperture closed by a frangible sheet material seal. When initial testing is to be conducted, an elongated assay cartridge is inserted vertically downward through the hollow plug. The bottom end splits open the frangible seal and enters into the subchamber containing the defined volume of the liquid sample, which becomes totally absorbed by a pair of elongated nitrocellulose strips, along which the liquid moves by capillary action to effect the assay tests.

15. A device for collecting, testing and transporting a liquid sample of bodily fluid or the like, which device comprises:
-
a container having a continuous sidewall that extends between a bottom wall and an upper opening through which a liquid specimen can be collected, said container providing a main chamber for storing such specimen and an upwardly open subchamber which is a part of said bottom wall, a lid for closing and sealing said upper opening to said container, said lid having a depending hollow plug section that terminates in a temporarily closed central aperture at its lower end, said plug section, at a location near its terminus, sealingly interengaging with said subchamber to create a closed cavity of defined volume that is isolated from communication with the remainder of said chamber, whereby a liquid sample of defined volume within said closed cavity can be tested without potentially contaminating the liquid specimen in the remainder of said container, and a test element proportioned to be received within said hollow plug section for insertion downward through said aperture by opening same, which element has (a) a casing that has a lower end portion for entry into said subchamber to contact liquid occupying said subchamber, (b) said casing having a port in said lower end portion to allow entry of said liquid sample thereinto, (c) an assay arrangement within said casing, and (d) a wicking strip arrangement for transferring liquid from said defined volume of liquid in said subchamber to said assay arrangement which produces a response that is detectable exterior of said container. - View Dependent Claims (16, 17, 18)

19. A method for collecting, initially testing and transporting a liquid sample of bodily fluid or the like, which method comprises:
-
collecting a liquid specimen in a container having a continuous sidewall that extends between a bottom wall and an upper opening and provides a main chamber for storing such specimen and an upwardly open subchamber, closing and sealing said upper opening to said container by securing a lid thereto, which lid has a depending hollow plug section that terminates in a temporarily closed aperture and sealingly interengages with said subchamber to create a closed cavity of defined volume that is isolated from communication with the remainder of said chamber, inserting a test element into said hollow plug and downward through said aperture by opening said temporary closure to contact liquid occupying said subchamber, so as to thereby test the liquid sample of defined volume without potentially contaminating the remainder of the liquid specimen within said container, and then transporting said sealed container to a separate laboratory for confirmatory testing of the remainder of the liquid specimen. - View Dependent Claims (20)
