Assaying device and method for in field urinalysis
First Claim
1. An assaying device for in field urine analysis comprising:
- a transparent container means having an opening for collecting a urine sample;
a cover means for sealing said opening of said container means; and
an assay assembly provided in said container means for chemically analyzing said urine sample, said assay assembly comprising;
a liquid impermeable backing;
at least one assay strip provided on a front surface of said liquid impermeable backing facing outwardly and viewable through said transparent container means;
a wicking means provided on a rear surface of said liquid impermeable backing separated from said assay strip by said liquid impermeable backing with one portion of said wicking means extending over a top edge of said liquid impermeable backing and overlapping a top portion of said assay strip;
a front cover means provided on said front surface of said liquid impermeable backing, said front cover means sealing said assay strip to said liquid impermeable backing at a bottom and two sides of said assay strip; and
a rear cover means provided on said rear surface of said liquid impermeable backing for sealing said wicking means to said liquid impermeable backing at two sides of said wicking means.

Abstract
An assay device for in field urine analysis including a container having an opening for collecting a urine sample, a cover for sealing the opening of the container and an assay assembly provided in the container for chemically analyzing the urine sample. The assay assembly comprises a liquid impermeable backing, a wicking material provided on a rear surface of the backing, at least one assay strip provided on a front surface of the backing and adjacent a top edge of the backing in contact with the wicking material, a front cover provided on the front surface of the backing for sealing the assay strip to the backing at a bottom and two sides of the assay strip and a rear cover provided on the rear surface of the backing for together with the front cover sealing said wicking material and the assay strip adjacent the top edge and two sides of said wicking material.

4. A method for in field urine analysis comprising the steps of:
-
introducing a urine sample into a transparent container having an opening after removing a cover from said opening, said transparent container further being provided with an assay assembly for chemically analyzing said urine sample, said assay assembly comprising;
a liquid impermeable backing;
at least one assay strip provided on a front surface of said liquid impermeable backing facing outwardly and viewable through said transparent container means;
