Device and method of measuring animal health
First Claim
1. A device for measuring attributes of urine comprising:
- a pad comprising a test patch layer comprising;
a plurality of different urine test patches, each different urine test patch comprising one or more respective urine test chemicals that change color responsive to a respective urine attribute;
a plurality of urine detection patches, wherein the urine detection patches are different from any urine test patch, and wherein each urine detection patch comprises one or more chemicals that change color responsive to presence of urine;
wherein each different urine test patch is at least partially surrounded by one or more of the urine detection patches;
the urine detection patches and urine test patches are arranged in a BAYER pattern, wherein the urine detection patches are arranged in a checkerboard pattern within the BAYER pattern and the urine test patches are distributed among the remaining location in the BAYER pattern;
a wicking layer above the test patch layer;
a transparent protection layer with holes, above the wicking layer;
a non-porous substrate below the test patch layer;
wherein the urine detection patches and the urine test patches are on the test patch layer.

Abstract
A test pad comprising multiple test patches and urine detection patches in an array is described. The test pad is suitable for automated urine analysis of multiple animals in a cage. Urine detection patches may be arranged in a BAYER pattern or as rings. Multiple layers, including a substrate, a wicking layer, a test patch layer, and optional protection layer serve to manage puddles of urine. Various isolation elements are described that keep urine puddles from spreading. Color reference spots on the pad are used for dynamic color determination of test patches. Urine detection patches start a read clock and identify which test patches are valid. Elements to hold and align the test pad are described. Methods of detection and reading are described.
