(c) Problems to be Solved by the Invention In the home-use urine sugar meter described above, the test subject must impregnate the test paper stick with urine, and insert the test paper stick soaked with urine into the measuring section. Not only is the removal work unsanitary, but it also has disadvantages such as the laborious work of cleaning the urine-stained testing area each time a measurement is performed. On the other hand, while the automatic urine testing device described above eliminates the filthy and troublesome work of a urinary sugar meter, it requires a pump and a valve to forcefully pump the washing water. In addition, the in-house feeding and automatic disposal mechanisms for test strip sticks are complex and prone to failure, and the equipment is large and expensive, and installing it in household toilet bowls requires costly construction work. There was a disadvantage.

The object of the present invention is to solve the above-mentioned problems and to provide an automatic urine testing device having a wheel-like structure that can be easily installed in, for example, a household toilet and can perform a clean automatic urine test. .

(d) Means and operation for solving the problem In order to achieve this object, the automatic urine testing device of the present invention has the following configuration.

The automatic urine test device includes a test paper stick insertion section, a urine test means that is movable forward and backward and arranged corresponding to the test paper stick insertion section, and a urine nozzle section at one end that is arranged so as to correspond to the test paper stick insertion section. a urine collection device having a urine collection port at the other end placed in a suitable position in the toilet bowl; a drain port of a cleaning water tank having one end with a cleaning nozzle part located corresponding to the test strip stick insertion part and the other end in the toilet bowl; and a cleaning means which communicates with the urine collection means through a branch pipe equipped with a valve.

In an automatic urine test device having such a configuration, when a test subject inserts a test strip stick into the stick insertion part,
For example, an insertion detection sensor placed in this insertion part detects the insertion and opens and closes the opening/closing part of the urine collection port.Here, when the test subject urinates into the toilet bowl (urine collection port), the urine is collected. It is sprayed onto the test paper through a pipe by a urine nozzle.

This urine collection pipe is equipped with, for example, a urine passage sensor, and when it detects that urine has passed, that is, urine has been sprayed, the opening/closing valve at the urine collection opening closes and the urine test sensor is driven. The mechanism is activated, and the urine test sensor approaches the test paper surface and detects the amount of color reaction light (detects the urine sugar level). After this, the urine test sensor retreats and returns to its original position. Here, when the person to be tested operates the drain lever of the wash water tank and opens the drain valve of the tank, the wash water is forced through the wash pipe to the wash nozzle, and is sprayed onto the test paper stick to wash it. Here, the test subject takes out the cleaned test paper stick from the insertion section and discards it. Thereafter, the valve of the branch pipe and the opening/closing valve of the urine collection port are opened, and the cleaning water flows through the branch pipe into the urine collection pipe and overflows from the urine nozzle and the urine collection port, completely cleaning the urine collection means.
