Abstract
Abstract An apparatus for testing urine consists of a container and a float. The float, in combination with the container, makes it possible to measure the specific gravity of a urine sample. The container is designed for holding test strips impregnated with reagents. Sediment contained in the urine can be collected for microscopic examination.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
129 words
A disposable, portable apparatus for carrying out a variety of tests on a urine specimen comprising a transparent container, a tightly fitting lid for said container, a vertical compartment adjacent a wall of said container and extending from the bottom of said container to a region below the top of said container, an outward flare in that portion of said container immediately above said compartment, said flare being so dimensioned that tipping the covered container to a horizontal position with the flare below the body of the container and bringing the container back to the vertical position first transports the urine in said container into said flare and then pours said urine into said compartment, and a float for measuring the specific gravity of the urine in said compartment.
Claim 2
Dependent Claim
129 words
A disposable, portable apparatus for carrying out a variety of tests on a urine specimen comprising a transparent container, a tightly fitting lid for said container, a vertical compartment adjacent a wall of said container and extending from the bottom of said container to a region below the top of said container, an outward flare in that portion of said container immediately above said compartment, said flare being so dimensioned that tipping the covered container to a horizontal position with the flare below the body of the container and bringing the container back to the vertical position first transports the urine in said container into said flare and then pours said urine into said compartment, and a float for measuring the specific gravity of the urine in said compartment.
Claim 3
Dependent Claim
81 words
The disposable, portable apparatus as defined in claim 1, and including channel defining means extending inwardly from the sidewall of said container forming a channel into which a strip of test paper impregnated with a suitable reagent can conveniently be inserted for reacting with one or more compounds which may be present in said urine, said wall of said container constituting one wall of said channel thereby providing maximum visibility for any color changes which may occur in said test paper.
Claim 4
Dependent Claim
46 words
The disposable, portable apparatus as defined in claim 1, wherein that part of the interior of said container which is exterior to said compartment tapers to a small cross-section, thereby gathering together and enhancing the visibility of any sediment which may settle out of said urine.
Claim 5
Dependent Claim
46 words
The disposable, portable apparatus as defined in claim 3, wherein the wall of said container has therein an essentially vertical groove extending from said region of small cross-section to the brim of said container to facilitate removal of saId sediment in a minimum quantity of liquid.
Claim 6
Dependent Claim
33 words
The disposable, portable apparatus as defined in claim 3, wherein said region of small cross-section ends in a cap removable from the bottom of said container, the sediment collected therein being simultaneously removed.
Claim 7
Dependent Claim
47 words
The disposable, portable apparatus as defined in claim 1, wherein said lid has a depression therein into which sediment which may settle out of said urine can be poured, and said lid with said depression is suitable for placing under a microscope for examination of said sediment.
Claim 8
Dependent Claim
35 words
The disposable, portable apparatus as defined in claim 1, wherein said lid includes a tube adapted to be placed in a centrifuge, so that sediment poured with urine into said tube may be rapidly separated.
Claim 9
Dependent Claim
48 words
The disposable, portable apparatus as defined in claim 1, wherein said float comprises a hollow tube capped at both ends and containing an object which brings the overall specific gravity of said float to a value slightly less than the minimum to be expected in any urine sample.
Claim 10
Dependent Claim
46 words
The disposable, portable apparatus as defined in claim 8, wherein said float can be used to measure the specific gravity of urine with either end up since said object will rest at that end which is downwardly disposed and will stabilize said float in that position.
