FIG. 7 is a perspective view showing an automatic urine testing device for mass medical examinations previously proposed by the applicant of the present application.

This automatic urine testing device includes a plurality of test strip sticks 83a.
A test strip storage cassette 83 is equipped with a feeding mechanism 82 that stores the sticks and feeds the sticks one by one to the test table plate 81, and the base end of the urine collection pipe 84a is communicated with the urine collection opening 85a of the toilet bowl 85. , a urine collection means 84 having a urine dripping part 84b at the tip fixed to a movable movable unit 86 equipped with a moving mechanism 86a, and a urine test means (a reflective sensor) 87 and water faucet 88a
A solenoid valve 88b is installed between the branches 84c of the urine collection pipe 84a.
The washing means 88 is connected to the washing means 88 via the washing means 88.

When measuring urine sugar, the test subject should hold the urine collection port (toilet bowl) 8.
Urinate at 5a. Urine is force-fed to the urine dripping part 84b by the liquid feed pump 84d. At this time, the test paper stick 83a is transported from the cassette 83 to the inspection table plate 81, and the blank value on the surface of the test paper is optically read by the reflective sensor 87 located above. Next, the moving plate 86 moves and after a predetermined amount of urine is dripped from the urine dripping part 84b located on the test paper surface, the moving plate 86 returns to its original position and the reflective sensor 87 located on the test paper surface develops a color. The amount of reaction light is optically read and the urine sugar level is detected in comparison with a blank value. In this state, the urine dripping part 84b corresponds to the waste liquid part of the examination table plate 81, and the remaining urine is drained from the waste liquid tray 89a via the surplus urine removal pipe 89.

(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 associated with a urinary sugar meter, it requires a pump to forcefully pump cleaning water.

In addition, the automatic feeding and discarding mechanisms for test strip sticks are complicated and prone to failure, and the device is large and expensive, and installing it in a household toilet bowl requires extensive construction work. There was a disadvantage.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide an automatic urine testing device with a simple 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 means with the urine collection opening at the other end placed in an appropriate position in the toilet bowl; one end with the cleaning nozzle part in correspondence with the test paper stain insertion part; and the other end connected to the bottom of the flushing water tank of the toilet through a valve. and a cleaning means in which a branch pipe equipped with a valve is connected to the urine collection means.

In an automatic urine testing device having such a configuration, when a subject inserts a test strip stick into the test strip stick insertion section, an insertion test sensor installed in the insertion section detects the insertion, and opens/closes the urine collection port. Open the department. Here, when the test subject urinates into the toilet bowl (urine collection port), the urine passes through the urine collection pipe and is sprayed onto the test paper surface from the urine nozzle. For example, this urine collection pipe is equipped with a urethral passage sensor, and when it detects that urine has passed, that is, urine spray has been performed,
At the same time as the opening/closing valve of the urine collection port is closed, the drive mechanism of the urine test sensor is activated, and the urine test sensor approaches the test paper surface and detects the color reaction light amount. After this, the urine test sensor retreats and returns to its original position.

At this point, the wash water pulp is opened and the wash water in the wash water tank flows towards the wash nozzle. In other words, the water pressure in the washing water tank forces the washing water to the front of the washing water pulp and stops, but when the pulp is opened, the washing water is sprayed from the washing nozzle onto the test paper surface and washes the test paper stick.

Here, the test subject takes out the cleaned test paper stick from the insertion section and discards it. After this, the on-off valves of the pulp and urine collection port of the branch pipe 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.
