Description of the Related Art Urine tests have become established as indispensable clinical information for screening tests because of their simplicity, speed, and reduction of the burden on patients. Urinalysis usually belongs to the "general test", and the result is highly likely to detect abnormalities in the kidneys, urinary tract and metabolic systems. One of the factors that has increased the importance of urinalysis is the development of urinalysis test strips. The urine test paper is obtained by attaching a piece of filter paper impregnated with a reagent of several millimeters square to one end of a plastic strip.

Things. The accuracy did not fall out of qualitative range,
In addition to the improvement of the reaction system and the coating technique, the advent of an automatic reading device using an optical system has enabled a certain amount of quantification (semi-quantification) in units of concentration such as mg / dl. Recently, test papers capable of detecting specific gravity and leukocytes have also appeared. Another device that can analyze urine is a biochemical analyzer.

わるものを用いて手で測定しなければならない煩わしさ
がある。In the urine test method using the test paper described above, since the surface of the test paper is wet with urine, light is irregularly reflected, measurement errors are liable to occur, and sample adhesion to the test paper is difficult. There is a drawback that it is not constant even when it is manually operated or automated, and the measurement error becomes large and the stability is lacking. In addition, the use of test strips results in only a semi-quantitative analysis and cannot be performed quantitatively, and in this case the urine volume test must be measured manually using a measuring cup or an alternative. There is annoyance.

Yes, not common. Therefore, an object of the present invention is to provide an automatic multi-item simultaneous urinalysis apparatus which is small, lightweight, relatively inexpensive, easy to operate, can simultaneously perform urinalysis over many items, and has high examination accuracy. .
