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.

Claims

1. An assaying device for in field urine analysis comprising:

a 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;

a wicking means provided on a rear surface of said backing;

at least one assay strip provided on a front surface of said backing and being in liquid transmittable contact with said wicking means adjacent a top edge of said backing;

a front cover means provided on said front surface of said backing for sealing said assay strip to said backing at a bottom and two sides of said assay strip; and

a rear cover means provided on said rear surface of said backing for together with said front cover means sealing said wicking means and said assay strip adjacent said top edge of said backing and two sides of said wicking means.

2. An assay assembly for chemically analyzing a urine sample, said assay assembly comprising:

a liquid impermeable backing;

a wicking means provided on a rear surface of said backing;

at least one assay strip provided on a front surface of said backing and being in liquid transmittable contact with said wicking means adjacent a top edge of said backing;

a front cover means provided on said front surface of said backing for sealing said assay strip to said backing at a bottom and two sides of said assay strip; and

a rear cover means provided on said rear surface of said backing for together with said front cover means sealing said wicking means and said assay strip adjacent said top edge of said backing top and two sides of said wicking means.

3. An assay assembly according to claim 2, wherein said rear cover is injected molded and said backing and front and rear cover are made from resilient materials.

4. A method for in field urine analysis comprising the tests of:

introducing a urine sample into a container having an opening after removing a cover from said opening, said container further being provided with an assay assembly for chemically analyzing said urine sample, said assay assembly comprising;

a liquid impermeable backing;

a wicking means provided on a rear surface of said backing;

at least one assay strip provided on a front surface of said backing and being in liquid transmittable contact with said wicking means adjacent a top edge of said backing;

a front cover means provided on said front surface of said backing for sealing said assay strip to said backing at a bottom and two sides of said assay strips; and

a rear cover means provided on said rear surface of said backing for together with said front cover means sealing said wicking means and said assay strip adjacent said top edge of said backing and two sides of said wicking means;

placing the cover means back on the container means to seal the opening; and

allowing the urine to wick up the wicking means and down the assay strip to react with the assay strip.
