Abstract: A urine detection device is disposed to a urine receiving surface of a toilet stool in which urine, diluting water and reagent are mixed by vertically moving a piston in the cylinder of the detection device, the reaction between them is detected by an electrode and the ingredient in urine is detected. Liquid in the cylinder is stirred by a stirring device to blown air into the reagent reservoir, by which oxygen is dissolved in the reagent. Cleaning liquid is sprayed from the nozzle to the electrode for flushing. An opening is disposed to a supporting wall of the toilet stool, through which the cylinder is detached or attached. The electrode is disposed such that its rear end is directed to the opening and detached or attached through the opening.

Abstract: An apparatus for examining urine for certain constituents thereof includes a vertically disposed cylinder for receiving urine therein. The cylinder includes a diametrically enlarged upper portion having an inside diameter which is larger than that of its remaining portion. A piston is vertically movably disposed in the cylinder. If the piston is lowered, urine can be stored in the cylinder. If it is raised, the urine is discharged from the cylinder, except that only a small portion thereof remains in a clearance defined between the piston and the diametrically enlarged portion of the cylinder. If the piston is lowered again, a reagent and water are supplied into the cylinder and mixed with the urine remaining therein. An electrode is connected to the cylinder for determining the concentration of sugar, etc. in the urine which has been mixed with the reagent and water.
