Abstract

PURPOSE:To prevent the lowering in the capacity of a sensor caused by contamination, constituting the titled apparatus so that the sensor responding to the specific component in urine is mounted to the drain flowline from a toilet bowl and prevented from contacting drainage when drainage is other that urine or no measurement is performed. CONSTITUTION:A sensor 1 can be freely moved to the predetermined position of the drainage flowline 7 of a toilet bowl 5 from the opening part provided to said drainage flowline 7 by a moving apparatus 2 and moved into the drainage flowline 7 by operating the operation switch 4 mounted to a control part 3. At the time of draining, washing water is supplied by opening a washing valve 6 and urine is discharged to the drainage flowline 7 along with water in the toilet bowl 5 urine diluted with water is contacted with the sensor 1. An electric signal corresponding to the concn. of the specific component in water is received by the control part 3 having a measuring part mounted therein and the concn. thereof is displayed by a mounted display part. By this constitution, because the sensor 1 is contacted with drainage only at the time of measurement, the lowering in capacity caused by contamination is reduced.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention provides a method for automatically testing urine without directly handling it by hand, which is equipped with a sensor that emits an electrical signal in response to components in urine. This article relates to a urine test device that can perform

[Technical background of the invention and its problems]

Urine tests are often used during health checkups because it is possible to determine the state of health and the degree of disease by analyzing and testing urine components.

1 Yu I ThJA +) - 4 Kogo Seita - 1 Ken 1 ■i also needs to be collected on a stick and then tested by an inspector using test reagents, test strips, or testing equipment. However, there were problems in terms of hygiene and complicated testing operations. However, in the case of diabetes, kidney disease, etc., the condition of the disease can be ascertained through a urine test, and it is also possible to obtain a guide for health management and diet control, and there has been a desire for an apparatus that can easily perform a urine test.

[Object of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a urine test device that is equipped with a sensor sensitive to a specific urine component in a drainage flow path from a toilet bowl, and that can perform urine tests easily and stably over a long period of time.

[Summary of the invention]

The present invention provides a urine testing device equipped with a sensor sensitive to a specific urine component, in which a control section of the testing device is equipped with an operation switch for the testing device and a display section for displaying test results, and the urine is discharged only when draining from the toilet bowl. This is a urine test device in which the senna is brought into contact with the liquid.

The urine test device of the present invention is equipped with a sensor sensitive to a specific urine component in a drain flow path from a toilet bowl.

This is a urinalysis device that measures urine components by bringing the waste water into contact with a sensor when draining water from the toilet bowl. It is characterized by having a structure like this.

According to the present invention, since the sensor comes into contact with the waste liquid only when measurement is necessary, it is possible to provide a urine testing device that is excellent in terms of contamination resistance and durability.

Note that any senna that can be used in the present invention may be used as long as it is necessary for testing the characteristics of urine, and generally any suitable senna can be used from among ion sensors, enzyme sensors, optical sensors, etc.

Furthermore, in the present invention, since the control section of the inspection device has an operation switch and a display device for displaying the inspection results, inspection and result judgment can be easily performed with simple operations, making it extremely effective in practice. I can say it.

[Embodiments of the Invention] FIG. 1 is a schematic cross-sectional view of a urine testing device showing one embodiment of the present invention. The sensor 1 is moved by the moving device 2 from an opening provided in the drainage channel 7 of the toilet bowl 5.

It can be freely moved to a predetermined position in the drain flow path 7. By operating the operation switch 4 provided in the control section 3, the sensor 1 is moved into the drainage channel 7. At the time of drainage, water for cleaning is supplied by opening the cleaning pulp 6, and urine is discharged together with the water in the toilet bowl 5 into the drainage channel 7, and the urine diluted with water comes into contact with the sensor 1. . A control section 3 having a built-in measuring section receives an electric signal corresponding to the concentration of a specific component in water, and displays the concentration on a display section provided therein. The maximum change value or integral change value of the electrical signal from the sensor can be read, calculated, and the results displayed. To calibrate the sensor, the zero point can be corrected using water in the toilet bowl, and the sensitivity can be calibrated using a standard sample in the form of a pellet or liquid.

FIG. 2 is a cross-sectional schematic diagram showing another embodiment.

The drain flow path has two legs of 7.8 mm, and sensor 1 is installed on one side. At the time of measurement, the discharge pulp 9 is opened to the side of the drain fluid channel 7, and most of the drain fluid is flowed into the channel 7, and the sensor 1 and the drain fluid are brought into contact with each other for measurement. When not measuring, the discharge pulp 9 opens to the flow path 8 side, and most of the waste liquid is discharged through the flow path 8.

Cleaning can be carried out by opening and closing the cleaning valve 6.6'.

〔Effect of the invention〕

According to the present invention, a urine test can be easily performed using the provided sensor, so that it can be done without having a very large effect on health management. Moreover, since the equipped sensor comes into contact with the liquid drained from the toilet bowl only during measurement, there is less performance deterioration due to contamination. Furthermore, since the sensor is constantly in contact with flowing wastewater, it is easy to maintain and prevent foreign matter from accumulating on the sensor surface, and it has the advantage of being usable at home.
