Urine testing apparatus capable of simply and accurately measuring a partial urine to indicate urinary glucose value of total urine
First Claim
1. A urine testing apparatus comprising:
- a sensor element, to detect components to be measured, having a urea detecting unit and at least one of a detection unit of sodium ions and a detection unit of chloride ions to detect urea and at least one of sodium ions and chloride ions that are components to be measured contained in urine;
a signal processing unit for converting a signal generated by detecting each component to be measured in said sensor element to detect components to be measured to a concentration of each component to be measured and for calculating a specific gravity of the urine on the basis of these concentrations; and
a display unit for displaying the urine specific gravity calculated in said signal processing unit and the concentration of at least one of the components to be measured.

Abstract
A urine multisensor has a sensor element to detect components to be measured, that has a urea component detecting unit and at least one of a detection unit of sodium ions and a detection unit of chloride ions to detect these components contained in urine, so as to know urine specific gravity on the basis of the concentration of each component yielded from the detection signal. Besides, a detection unit of glucose component is added in necessity to add a structure to correct a urinary glucose value (glucose level) with the urine specific gravity finally resulting in that the urinary glucose value of total urine excreted for 24 hours can be simply and accurately known from the partial urine.
