Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a toilet that can determine the health condition by determining the concentration of sugar, bilirubin, etc. in the urine from the urine that is urinated while using the toilet. It is.

(Prior art and its problems) Conventionally, diabetes, etc., have been determined by testing the sugar content in the urine, and the quality of kidney function has been determined by testing the concentration of bilirubin in the urine. However, such tests are usually performed by specialized doctors and are carried out at special institutions such as hospitals.
It has been difficult to determine the concentration of sugar or bilirubin in urine at home. However, recently, a test section containing a reagent has been installed in the toilet bowl, and the urine urinated into the test section is reacted with the reagent in the test section, and the color change in the test section determines the presence or absence of sugar in the urine. However, such toilets simply determine the sugar content in urine by color change, and it is not possible to accurately determine the concentration of sugar content, etc. In some cases, the reaction between the reagent and urine is inaccurate, or the reagent is not fully supplied to the determination section, so that the determination function cannot be fully demonstrated. In addition, since a large amount of urine is directly mixed with the reagent and reacted, the oxidation effect of the reagent may be incomplete and an incorrect color reaction may occur.Furthermore, it is necessary to completely wash the reagent and urine after the reaction. However, there were problems in that it was insufficient, did not function accurately, and lacked reliability.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and the present invention is made by accurately collecting urine urinated while using a toilet bowl and using it as a reagent provided in the toilet bowl. The purpose is to provide a urine component detection toilet that can reliably react, extract the concentration of sugar, etc. in urine from the reaction state as an electrical signal, and display it numerically. The present invention is equipped with an enzyme reagent that can react with components in urine excreted in the urine, and an electrode that can output the reaction state of the enzyme reagent and the urine components to the outside as an electrical signal.

(Function) The toilet bowl is equipped with an enzyme reagent and an electrode, and when the user urinates on the body surface of the toilet bowl, the components in the floor react with the enzyme reagent depending on the concentration of the components in the urine. The electrode can output the reaction state to the outside as an electrical signal, and the concentration of sugar, etc. in the urine can be electrically extracted to the outside and displayed as an accurate numerical value.

The structure is such that a gap M is formed between the outer peripheral wall of the piston and the upper inner peripheral wall of the urine collection cylinder 30.

On the other hand, the pump cylinder 31 coaxially connected to the lower end of the urine collection cylinder 30 has a cylindrical pump chamber P inside, and its upper end fits into the inner wall of the lower end of the urine collection cylinder 30. It can be integrated with the urine collection cylinder 30 by screwing a set screw 38 from the outside into a screw hole 301 formed at the lower end of the urine collection cylinder 30.

A rod hole 31e is formed in the center of the base 31a at the lower end of the pump cylinder 31, through which the piston rod 32b of the piston 32 can be inserted, and two O-rings 04 are fitted into the rod hole 31e. At the same time, a dilution water guide hole 31c and a reagent guide hole 31d are formed in the horizontal direction on the sides thereof. Four screw holes 31b are drilled in the peripheral edge of the base 31a, into which screws 40 can be screwed, and the pump cylinder 31 is connected to the base of the urine collection device 7 through the screws 40. frame 41

11 and 7 will be explained based on the flowcharts shown in (b) and (c).

That is, the control panel 19 is constituted by a microcomputer, and a control program shown in FIG. 15 is stored in an internal ROM.

In FIGS. 15(a), (b), and (c), first, when the power plug is turned on (Sl), the proximity switch 28 detects the remaining amount of reagent in the reagent cartridge tank 21 (S3). If there is not enough reagent, the reagent out indicator lamp L6 on the operation panel 51 shown in FIG. 11 is turned on (S4). If there is sufficient reagent remaining, the power lamp L5 is lit (

At the same time, the solenoid valve is turned on and fully opened (S25), and the water in the pump chamber P is discharged into the bowl portion 8 of the toilet bowl via the drain pipe Y. After the solenoid valve D2 is set to 0FFa, when the user sitting on the toilet main body 2 urinates (S26), the urinated urine is blown toward the third body surface 8c of the bowl part 8 of the toilet main body 2, and Urine flows into the urine collection chamber C of the urine collection cylinder 30, which opens upward to the bowl surface 8c. That is, since the screw 32 is lowered, the urine collection chamber C is empty, and the urinated urine is collected in the urine collection chamber C.

In this state, when the measurement switch E on the operation panel 51 is turned on (S27), the stepping motor 50 rotates and the piston 32 starts to rise (S31). However, even after 10 minutes have passed after the switch E was pressed, the switch E
When 2 is not pressed (828), the program in C returns to the above (S8) and the stepping motor 5o
is repeatedly operated to clean the urine collection device 7, and then stopped (S8-520). Also, when the preparation switch E is pressed, the lamp L1 blinks at intervals of 52 seconds.

, the reagent is sucked into the pump chamber P (835N
). After the electromagnetic valve D4 is closed, the electromagnetic valve D3 is opened (S37), the stepping motor 50 is reversed, and the piston 32 starts moving downward (336). That is, the reagent in the pump chamber P is sent from the pump chamber P to the urine collection chamber C, and in the urine collection chamber C, urine, dilution water, and reagent are mixed.

Note that since the reagent is sprayed in a diffused manner into the urine collection chamber C through the nozzle cap 35, the reagent, urine, and dilution water in the urine collection chamber C are mixed extremely smoothly.

In this example, in (S31) to (S37), most of the urine collected in the urine collection chamber C is diluted and discharged, and then mixed with the reagent. This is because the oxidation of glucose in urine is better carried out by the M reagent when urine is reacted with a large amount of reagent (increasing the dilution ratio). It is set to about 30 to 50. In other words, in the past it was difficult to remove a small amount of urine in the toilet bowl, but now
Through this kind of control, the same effect as collecting only a small amount of urine can be obtained.

The time when the reagent, urine, and dilution water are mixed in urine collection chamber C by (S36) and (S37) becomes point a shown in FIG. A phenomenon in which glucose is oxidized by the enzyme reagent and the resistance value between the electrodes of the oxygen electrode 34 increases and the current value decreases as oxygen decreases is then input from the oxygen electrode 34 for about 10 seconds (S39).

That is, as shown in FIG. 13, when there is a large amount of glucose in the urine, oxygen is consumed by the enzyme reagent at an extremely high rate, so the current value of the oxygen electrode 34 decreases rapidly, and the glucose content decreases. When the amount is small, no difference occurs in the current value. Therefore, in (S39), the change value of the current caused by the oxygen electrode 34 is measured for 10 seconds. This measured value is input to the CPU in the control panel 19. Also, at the same time (
At S38), the temperature inside the urine collection chamber C is measured via the thermistor 37, and this measured value is also input into the CPU. That is, when the temperature is low, the reaction between the glucose in the urine and the enzyme reagent is not active, and the contrast line between the reaction rate and concentration as shown in FIG. 14 is created depending on the temperature.

The comparison line shown in FIG. 14 is based on the measured value of the change in current for 10 seconds from point b to point C in FIG. If the horizontal axis is the velocity from point b to point C in Figure 13 (current change value ΔA/ΔT per 10 seconds), the vertical axis shows the concentration of glucose in the urine, and (
Based on the speed input in step 339), the glucose concentration can be instantly known. At that time, the concentration value corresponding to the temperature value inputted from the thermistor 37 (338) is the 14th
It is calculated in the CPU from the line section in the figure (S42). This density value is displayed as a number on the display section 51a of the operation panel 51 (348).

Also, at the end of the measurement, an electronic buzzer gives a signal (S
47), after the display has been performed for a predetermined time, the measurement lamp L
, is turned off, and furthermore, the lamp L is turned off (S49
．． 550).

When the concentration of glucose is displayed on the display section 51a for a predetermined second, the stepping motor 50 is rotated and the piston 32
540), and the mixture of reagents, urine, and dilution water in the urine collection chamber C is discharged into the pot part 8. At that time, the solenoid valve is opened and dilution water flows from the low tank 6 into the pump chamber P into the wood pipe Y2. The water is introduced through the water conduit Y (S41).

Next, the solenoid valve D5 is turned on and external tap water is supplied to the water pipe Y.
The water is introduced into the urine collection chamber C through the tap water, and the inside of the urine collection chamber C is washed with tap water (S44). At this time, the stepping motor 50 is rotated and the piston 32 is lowered (545),
At the same time, the solenoid valve is fully opened (846), and the pump chamber P
The dilution water inside is introduced into the urine collection chamber C. Therefore, the inside of the water conduit YI and the mixing pipe Y will be cleaned.

After the solenoid valve D3 is closed, the stepping motor 50 is reversed again and the piston 32 is raised (S13), and at the same time, the solenoid valve D3 is opened (S14) and the pump Low tank 6 in room P
More cleaning water is sucked in. At this time as well, the water conduit Y will be cleaned. When the stepping motor 50 is reversed again and the piston 32 is lowered (515) and the solenoid valve D2 is opened (S16), the cleaning water is drained from the pump chamber P via the water pipe Y4 and the drain pipe Y5. The drain pipe Y6 can be completely washed with the washing water. After this, further (517), (81g),
Through (S19) and (S20), the inside of the pipe is successfully cleaned, and the self-cleaning action of the urine collection device 7 is completed.

In this example, as the piston 32 moves up and down, dilution water is introduced into the pump chamber P, and the dilution water is mixed with the urine collected in the urine collection chamber C to dilute the urine. Furthermore, the diluted urine is discharged to the outside as the piston 32 rises, and the reagent sucked into the pump chamber P is transferred to the urine collection chamber C against the diluted urine slightly left in the gap M by the downward movement of the piston 32. A large amount of reagent is mixed into a small amount of urine, and the concentration of glucose in the urine due to the oxidation reaction by the reagent can be successfully measured and displayed numerically. In conjunction with the movement, cleaning water is passed through the urine collection chamber C, pump chamber P, and surrounding piping, allowing them to be properly cleaned and self-cleaned, allowing new measurements to be taken.

Furthermore, when the user presses the dilution water replenishment button Es, (
S51. ) and lamp L blink (S5).

That is, the stepping motor 50 is turned on (S53
), the piston 32 is raised until the slide table 43 comes into contact with the limit switch 47 (S55), at which time the solenoid valve is opened (S54), and cleaning water is sucked into the pump chamber P from the low tank 6. As the stepping motor 50 reverses again, the piston 32 descends (556), and at the same time, the solenoid valve D3 is opened (357), so that the cleaning water in the pump chamber P is sent to the urine collection chamber C. By reversing the stepping motor 50 again, the piston 32 is raised by 558), and at the same time, the solenoid valve D is
1 is opened, the cleaning water flows into the pump chamber P again (S59).
0 is reversed, the piston 32 descends 560
), the solenoid valve is simultaneously opened, and washing water is sent from the pump chamber P to the urine collection chamber C (S61). This (S58)~
By repeating the steps up to (S61) about five times (S62), air bubbles contained in each pipe are removed.

This operation is performed, for example, immediately after installing the urine collection device 7, and removes air bubbles in the piping to prevent the urine dilution rate and reagent mixing rate from changing due to air bubbles, and to obtain accurate measurement values. This is done by repeatedly cleaning the entire pipe over and over again to remove any air bubbles inside. Finally, the solenoid valve D5 is opened and the cleaning is completed with tap water (S64), and then by the program B (S13)~
The steps up to (S20) are performed.

Also, when the user presses the reagent supply switch E4,
Processing in program E is performed. That is, this is an operation performed when the reagent cartridge 21 is replaced.

At that time, when the switch E is turned on (S65), the lamp L4 blinks (566), and the stepping motor 5
0 rotates and the piston 32 rises (567), the solenoid valve D4 is turned on (S68), and the reagent is sucked into the pump chamber P.

When the limit switch 47 is turned on (S69), the stepping motor 50 reverses and the piston 32 starts to descend (570), and at that time the solenoid valve D3 is opened (S69).
71), a reagent is introduced from the pump chamber P into the urine collection chamber C.

The stamping motor 50 is reversed again (572),
Simultaneously with the rise of the piston 32, the solenoid valve D4 is opened (S73), and the reagent is introduced into the pump chamber P again. When the piston 32 descends by reversing the stepping motor 50 again (S74), the reagent in the pump chamber P is introduced into the urine collection chamber C. At that time, solenoid valve D3 is opened (S75). This cycle from (S72) to (S75) is repeated five times (576) to remove air bubbles from the reagent pipes, that is, the reagent pipe Y6 and the water conduit pipe Y4. Finally, the electromagnetic valve D5 is turned on (S77), the reagent in the urine collection chamber C is washed, and air bubble removal from the reagent pipe is completed. After completion, the lamp L4 is turned off (378).

In this example, an example was shown in which glucose oxidase was sealed in the reagent cartridge tank 21 to measure the concentration of glucose in urine, but the reagent cartridge tank 21
If bilirubin oxidase is increased in the blood, the concentration of bilirubin in the urine can be measured, which is useful for medical diagnosis of liver disease. Kirani reagent cartridge tank 21 contains lactate desidrokinase (Lactate D
ehydr.

If a reagent containing genase as a main component is included, the concentration of lactic acid in urine can be measured well.

Furthermore, if cholesterol oxidase is sealed in the reagent cartridge tank 21, the concentration of fats and oils in urine can be easily determined. Note that these reagents may be individually sealed in the reagent cartridge tank 21, or a mixture of each reagent may be used. In addition, each reagent was used alone to detect not only glucose but also bilirubin in urine.

When using a toilet bowl with the function of simultaneously measuring lactate, oil and fat, etc., a plurality of independent urine collection devices 7 are installed in the toilet bowl using independent piping, and each urine collection device 7 measures glucose concentration, bilirubin concentration, and lactate. It is also possible to measure the concentration and oil/fat concentration at the same time.

In this way, in this example, the urine collection device 7 has a piston structure, and the volume of the lower pump chamber and the upper urine collection chamber is alternately changed by the vertical movement of the piston, so that dilution water, reagents, etc. can be properly pressurized into each chamber. During press-fitting, the mixing action of the nozzle fitting 35 allows the urine and reagent to be well mixed in the urine collection chamber, allowing the reaction to occur extremely well. Moreover, since only a small amount of urine remaining in the gap M is collected and reacted with a large amount of reagent, it is possible to measure glucose, etc. in the urine extremely accurately.

In addition, in this example, the rotary solenoid 14 is installed inside the low tank 6, and since the movable range is narrower than the conventional sliding type solenoid with two downward movements, it can be installed compactly inside the low tank 6. It is possible to secure a sufficient water storage capacity of the rotary tank 6, reduce noise during drainage due to the quietness of the rotary solenoid 14, and use a photoelectric switch using an optical fiber to operate the rotary solenoid 14. 29, the photoelectric switch does not protrude into the low tank like in the past, and the sensor 1 can be placed compactly in the low tank.
5 can be fixedly installed, and since the fiber does not involve electrical wiring, it can also be piped underwater in the low tank, and the photoelectric switch does not cause electrical failure due to moisture in the low tank, unlike conventional methods. , can maintain good working condition.

(Effects of the Invention) The toilet bowl of the present invention is capable of outputting an enzyme reagent capable of reacting with components in urine urinated on the surface of the toilet bowl and the reaction state of the enzyme reagent and the components in urine to the outside as an electrical signal. Equipped with an electrode, the urine is reacted with a reagent, and the reaction state is output as an electrical signal to the outside through the electrode, and the amount of sugar in the urine can be measured numerically without the need for color judgment as in the past. etc., and has the effect that health conditions can be determined extremely accurately.
