DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

2. Description of the Related Art Urine is an important source of information on the health of individuals, and various functional disorders can be examined by quantitative analysis of urine components. Therefore, when an individual urinates on a daily basis, a proposal has been made to add a function of analyzing a urine component to a toilet at home or at work in order to detect a functional disorder at an early stage by analyzing the urine. I have.

An example disclosed in Japanese Patent Application Laid-Open No. 10-170512 will be described with reference to FIG. A urine reservoir 2 is formed on the bowl surface of the toilet bowl 1, and urine discharged from an individual flows and accumulates. The sensor 3 is detachably attached to an arm 4, and the arm 4 is attached to be slidable up and down along a slider 5. The slider 5 is rotatably mounted at the upper end. Reference numeral 6 denotes a preservation liquid container, and these driving mechanisms and preservation liquid are stored in a box provided on the upper surface of the toilet. With this configuration, at the time of measurement, the slider 5 rotates and tilts at a predetermined angle, then the arm 4 descends, and the sensor 3 analyzes the urine component when immersed in the urine of the urine reservoir 2. After that, the sensor 3 is washed by draining, the arm 4 is raised and rotated to maintain the vertical state, and then the arm 4 is lowered to insert the sensor 3 into the storage liquid container 6. That is, the sensor 3 is in contact with the storage liquid during non-measurement. Sensor 3
Is a sensor capable of detecting the concentration of a specific component in urine as an amount of electricity by an enzyme reaction using an enzyme and an electrode. The sensor can be repeatedly used by immersing it in a storage solution when not in use.

[0004]

However, there is a problem that it is difficult to replace the sensor with the above-mentioned conventional urinalysis apparatus. That is, although the enzyme sensor can be used repeatedly by immersing it in a storage solution when not in use, the number of repetitions that can be used without causing sensitivity deterioration is limited to one hundred to several hundred times, and only that If used several times, it must be replaced with a new sensor. In the above configuration, the position where the enzyme sensor stops is either in the urine reservoir in the toilet bowl or in the storage liquid container, and the sensor is replaced there, or the enzyme sensor of the storage liquid container moves from the urine reservoir. , And the sensor must be replaced there. Either way, it's in the toilet bowl or on the toilet. If the sensor is replaced at this position, if the sensor is dropped at the time of replacement, it will fall into the toilet drain. And can clog drains,
There is also disgust when picking it up.

FIG. 3 is a perspective view showing a state in which the above-described components are put in a case and attached to a toilet. That is, 31
Is a case that houses parts such as the motor 10, the storage liquid container 6, and the substrate 22, and is attached to the rim side of the toilet 1 by the toilet mounting portions 23 and 24. On the upper surface of the case 31, a measurement switch 33, a sensor exchange switch 32 as a sensor exchange instruction unit, and a display unit 30 are provided. The figure shows a state in which the toilet seat 34 is erected and a state in which the sensor 3 is exposed to the urine receiving position in the bowl of the toilet 1. That is, FIG.
Is the first position for receiving urine in the toilet bowl, where F is the position of the sensor 3 shown in FIG.

In general, a man stands in a standing posture and stands up the toilet seat 34 to urinate. In this case, since the location of the sensor 3 and the urination curve can be visually recognized, it is easy to hit urine regardless of the location of the sensor 3. On the other hand, generally, a woman urinates in a seated position with the toilet seat 34 depressed. In this case, the location of the sensor 3 and the urination curve cannot be seen. Therefore, it is desirable to make the sensor 3 protrude to a place where urine naturally hits the sensor when a woman urinates in a sitting posture, and the third position F is set slightly behind the center of the toilet.

The structure of the planar enzyme sensor 3 will be described with reference to the sectional view of FIG. This is disclosed in Japanese Patent Application Laid-Open No. 304330, and includes a polyimide film (PI film) 35, a pair of metal electrodes 36 as hydrogen peroxide electrodes, a polymer film 37 having two layers, An immobilized enzyme film 38 comprising a layer, a polymer adhesive film 39,
Polycarbonate film (PC
Film 41).

The pair of metal electrodes 36 formed on the PI film 35 captures an increase or decrease in oxygen or hydrogen peroxide due to an enzyme reaction in the enzyme film 38 as a change in oxidation current. Polymer film 37 formed on metal electrode 36
Is formed by coating the metal electrode 36 and heating it further. By this heat treatment, the permeability of the electrode interfering substance can be sufficiently restricted while maintaining the permeability of hydrogen peroxide as compared with the case of only the coating, and the inherent properties of the material are improved. Therefore, even if urine comes into direct contact with the sensor 3, the urine component can be analyzed.

As the immobilized enzyme film 38 formed on the polymer film 37, glucose oxidase is used. In this case, the enzyme reaction is Glucose + O ₂ → gluconic acid + H ₂
O _2, and the accompanying degradation of glucose, oxygen is consumed along with the hydrogen peroxide is generated, gluconic acid occurs.

The hydrogen peroxide generated here is applied to the metal electrode 36.
Is decomposed into water and oxygen while emitting electrons by the catalytic action of. By measuring the emitted electrons as a current, the sugar concentration in urine can be measured.

Next, the operation of the control means 27 and the signal processing means 29 at the time of measurement will be described with reference to the flowchart of FIG. If it is assumed that the urine test apparatus is not used until then, the sensor 3 is stationary while being inserted into the storage liquid container 6. That is, the sensor 3 is at the second position D shown in FIG. The subject first stands in front of the toilet 1 (mainly male) or sits on the toilet seat 34 (mainly female). Here, when the measurement switch 33 is pressed (ST101), the motor 10 rotates a predetermined amount counterclockwise by the output from the control means 27 (ST10).
2) The sensor 3 exits the storage liquid container 6 and passes through the guide means 15 outside the bowl and the guide switching means 13 to be exposed in the substrate 22.

Therefore, the control means 27 is provided with the guide switching means 13
Is driven from left to right as shown in FIG. 1 (ST10).
3). Then, a signal is output to the motor 10, and when the motor 10 rotates clockwise by a predetermined amount (ST 104), the sensor 2 passes through the guide means 14 in the bowl from the guide switching means 25 and moves a little to the center in the bowl of the toilet 1. And stop. That is, the sensor 3 stops at the first position F shown in FIG. In this state, the sensor 3 is energized (ST105) to make it detectable. Here, the subject starts urinating, and the sensor 3 receives the urine discharged from the subject.

Since the output of the sensor 3 starts to change due to the contact with the urine, it is known that the urine has been received (ST10).
6). The signal processing means 29 further calculates the concentration of sugar contained in urine from the change in the output, and displays it on the display means 30 (ST107). Next, the solenoid valve 21 is opened (ST10).
8) The washing water flows out from the washing nozzle 20. The sensor arm 4 exposed in the toilet 1 due to the outflow of the washing water
Can be washed. The motor 10 is rotated counterclockwise while the washing water continues to flow (ST10).
9). Here, the sensor 3 starts to move toward the in-bowl guide means 14, and the sensor arm 4 moves to the sensor holding portion 7,
Further, the sensors 3 are sequentially washed.

Preferably, before the sensor 3 enters the guide means 14 in the bowl, the motor 10 is temporarily stopped, the sensor 3 is flooded with washing water, and the completion of washing is detected from the output of the sensor 3 (ST110). The electromagnetic valve 21 is preferably closed (ST111). This is because a sufficient amount of washing water can be applied to ensure washing. At the same time, the energization of the sensor 3 is stopped (ST1).
12). This is because the detection by the sensor 3 becomes unnecessary, so that useless power consumption is prevented. When the motor 10 is further rotated counterclockwise by a predetermined amount in response to an output signal from the control means 27 (ST113), the sensor 3 passes through the guide switching means 13 from the in-bowl guide means 14 and is exposed in the substrate 22.

Here, the control means 27 is the guide switching means 13
And moves from right to left shown in FIG. 1 (ST
114). Then, a signal is output to the motor 10 and the motor 10 is rotated clockwise by a predetermined amount (ST115). Then, the sensor 3 passes through the guide means 15 outside the bowl from the guide switching means 13 and advances into the storage liquid container 6, stops at the second position D shown in FIG. 2 again, and comes into contact with the storage liquid.

When the measurement is carried out by bringing the sensor 3 into contact with urine, it is preferable to provide the sensor 3 for a predetermined time after cleaning, until the next measurement is permitted. This is because although the substance in the immobilized enzyme can be removed by washing, it takes time for the substance attached to the electrode surface to be sufficiently removed by the electrochemical action. For this purpose, the timer is started when the washing is completed or when the storage solution is stored, and the input of the measurement switch 33 is not accepted for a predetermined time (ST116). When the measurement switch 33 is pressed again after a predetermined time has elapsed, the above operation is repeated.

Next, the operation of the control means 27 and the signal processing means 29 at the time of sensor replacement will be described with reference to the flowchart of FIG. If it is assumed that the urine test apparatus is not used until then, the sensor 3 is stationary while being inserted into the storage liquid container 6. That is, the sensor 3 is at the second position D shown in FIG.
It is in.

Here, the user turns the attaching / detaching member 19 shown in FIG. 2 to replace the storage solution to be replaced simultaneously with the replacement of the sensor 3, and removes the storage solution container 6 from the outside-bowl guide means 15. Then, the exchange switch 32 is pressed (ST20).
1).

Here, the control means 27 outputs a signal to the motor 10 and rotates clockwise by a predetermined amount (ST202). Here, the sensor 3 moves from the second position D to the third position E shown in FIG.
Move to and stop. Here, power is supplied to the sensor 3 to detect whether the sensor 3 has been replaced (ST20).
3).

The user removes the sensor 3 and the sensor holder 7 from the sensor arm 4 at the third position E, and mounts a new sensor 3 and the sensor holder 7 on the sensor arm 4.
The mounting determination unit 31 of the signal processing unit 29 determines whether the sensor 3 and the sensor holding unit 7 are mounted on the sensor arm 4 using a switch unit or a sensor resistor. Then, from the mounted state through the detached state (ST204)
When the mounting state is determined again (ST205), it is determined that the sensor 3 and the sensor holding unit 7 have been properly replaced.

Then, the power supply to the sensor 3 is stopped (ST
206) At the same time, the control means 27 outputs a signal to the motor 10 and rotates a predetermined amount in the counterclockwise direction (ST207) to move the sensor 3 from the third position E to the second position D shown in FIG.
Move to and stop.

Then, the user mounts the storage solution container 6 containing the new storage solution again on the sensor arm 4 to complete the replacement operation of the sensor 3.

In the above description, the replacement of the sensor
Although the replacement of the sensor holding section 7 has been described, the sensor arm 4 may be replaced. The sensor arm 4 is also exposed in the toilet bowl and is a part to which urine is applied. Although the sensor arm 4 is cleaned, it may be gradually contaminated during repeated use. For this purpose, the sensor arm 4 is preferably detachable from the rack 8.
