Description: TECHNICAL FIELD The present invention relates to a toilet bowl that can easily measure components such as protein and glucose in urine.

(Prior art and its problem) Conventionally, as a toilet bowl provided with a device for measuring the concentration of a specific component in urine, there is one disclosed in Japanese Patent Laid-Open No. 59-217844. The collected urine was introduced into a liquid chromatograph through a filter by a pump and passed through the liquid chromatograph to separate a specific component in the urine.

Since liquid chromatography is used in such a conventional urine component measuring toilet, this device is extremely expensive and difficult to handle, and once used for measuring urinary components, the following In order to perform the measurement, sufficient cleaning must be performed, and it takes a long time for each measurement, resulting in poor efficiency and impracticality.

(Means for Solving the Problems) The present invention has been devised in view of the above-mentioned conventional problems, and is a compact urine component measurement capable of continuously measuring the concentrations of various kinds of urine components in a short time. For the purpose of not providing a toilet bowl, the gist thereof is a feeding conduit for passing collected urine, and a gas injector for injecting gas into the feeding conduit to divide the urine into sample compartments, In the urine component measuring device provided with a reagent injector for injecting a reagent into each urine divided into sample compartments, and a concentration measuring device for detecting a urinary component concentration in each sample compartment, the delivery conduit It is said that a three-way solenoid valve connected to the wash water storage tank is provided on the upstream side of the above, and the three-way solenoid valve is controlled to allow the wash water to flow into the feed pipe.

(Operation) Gas is injected from the gas injector into the urine flown into the feeding pipeline to divide the urine into sample compartments, and the reagent injector into which the reagent is injected into each divided sample compartment, In that state, after detecting the urinary components in each sample compartment with a concentration meter and completing the measurement of the collected urinary components, open the three-way valve and wash from the washing water storage tank in the feeding pipeline. Pour water, wash the inside of the feed line to satisfactorily remove residual liquid such as urine and reagents, and clean the inside of the feed line for measurement of urine to be collected next. Accurate measurements can be obtained for each collected urine.

In addition, after flowing the wash water into the supply pipeline, control the three-way solenoid valve to stop the flow of the wash water, and send air from the three-way solenoid valve into the feed pipeline to The wash water can be partitioned by air, and the three-way solenoid valve is closed to immediately send the next collected urine into the feed line, and as described above,
It is possible to measure a new component in urine. At this time,
In the supply pipeline, the washing water and new urine are well separated by the layer of air sent from the three-way solenoid valve, and the washing water does not mix into the urine, and the urine is continuously different at high speed. It is possible to continue the measurement of the urinary components of the.

(Example) Hereinafter, the Example of this invention is described based on drawing.

FIG. 1 is a schematic configuration diagram of the urine component measuring toilet bowl of the present example, in which a horizontal horizontal portion 2 is formed in the front part of the toilet bowl 1a of the toilet body 1 constituting the urine component measuring toilet bowl A. A urine collector V is attached from the outside to the horizontal portion 2 in a hanging shape.

The urine collector V is connected to the dilution tank 3 via an electromagnetic valve b and can introduce dilution water into the inside.

The three-way solenoid valves a and c are connected to the urine collector V, and the three-way solenoid valve a is connected to a feed line for sending urine. In this example, the feeding pipeline is divided into four first feeding pipeline 4a, second feeding pipeline 4b, and third feeding pipeline 4
c, the fourth supply pipeline 4d, the downstream ends of the respective supply pipelines 4a, 4b, 4c, 4d are merged again and connected to the return pipeline 10, and this return pipeline Reference numeral 10 is connected to the discharge portion 1b of the toilet body 1. A suction pump 9 is arranged in the return conduit 10, and the suction pump 9 is driven to drive the first to fourth feeding conduits 4 a, 4 a.
Urine is sucked from the urine collector V into b, 4c, and 4d.

A three-way solenoid valve d ₁ , a three-way solenoid valve e ₁ , a mixing coil M _1, and a concentration measuring device 7 are provided in the first feeding line 4 a.
a is arranged in order from the upstream to the downstream side, the gas injector 5a is connected to the three-way solenoid valve d _1, and
As shown, when the three-way solenoid valve d ₁ is turned on and off, air is intermittently supplied from the gas injector 5a into the first feeding pipe line 4a, and the first feeding pipe line 4a. A bubble layer 16 is formed in the urine sample 15 that is allowed to flow inside, and the urine sample 15 can be divided into sample sections 17 between the bubble layers 16 and 16.

Moreover, said three-way solenoid valve e ₁ is connected to a reagent insertion unit 6a, this is the reagent charging unit 6a reagent for protein measurement in urine is stored in this example, the three-way solenoid valve e ₁ is sub-controllers By being controlled by S ₁ and being turned on and off intermittently, as shown in FIG.
A reagent is intermittently introduced into the sample compartments 17 to form reagent layers t ₁ and t ₂ . still,
The sub controller S ₁ is connected to and controlled by the main controller 11.

Further, the mixing coil M ₁ is for favorably mixing the reagent layers t ₁ and t ₂ put in the sample compartments 17, and for improving the mixing state of the reagents in the sample compartments 17. belongs to.

The concentration measuring instrument 7a is composed of a spectrophotometer, and the sample compartment 17 flowing in the first feeding conduit 4a.
It is possible to project light from an LED for projecting light on a sample therein and measure the absorbance at a specific wavelength with a photodiode for receiving light.

That is, generally, the wavelength of light having the highest absorption varies depending on the type of substance, and the wavelength of light that is easily absorbed varies depending on the type of urine component. Therefore, by measuring the absorbance of light of a specific wavelength using a photometer (not shown) connected to a photodiode, it is possible to detect the concentration of a specific urine component, and further, a color reaction with a specific component in urine. Since the reagent showing the above is used, the concentration of the urinary component can be detected more easily by measuring the absorbance. For example, the maximum absorbance wavelength of protein in the urine component is 600 nm, and if an orange LED (peak wavelength 610 nm) having a peak wavelength close to this wavelength is used, the peak wavelength 610 emitted from the orange LED is
The light of nm is absorbed by the protein in urine, and the passing light is received by the photodiode for receiving light, and the protein concentration in urine is measured from the relational expression between the output from this photodiode and the protein concentration. Can be done. Incidentally, the concentration measuring device 7a
A display device 8 composed of a CRT or the like is connected to the display device 8 and the measured value of the protein concentration is displayed on the display device 8.

Incidentally, in this example, the flow cell 20 constituting the spectrophotometer of the concentration measuring instrument 7a has a structure as shown in FIG. That is, a flat plate portion 20b formed in a flat plate shape in a communication state is formed in the cylindrical cylindrical portion 20a having a cross-sectional area Z ₁ which is connected to the first feeding pipeline 4a in a communication state,
The cross-sectional area of the flat plate portion 20b is Z _2, and the cross-sectional area Z ₁ of the cylindrical portion 20a and the cross-sectional area Z ₂ of the flat plate portion 20b are the same cross-sectional area. The LEDs 21 and the photodiodes 22 are arranged in a side-to-side relationship in the longitudinal direction of the flat plate portion 20b so that the light from the LED 21 is reflected by the flat plate portion 2
The photodiode 22 is configured to receive light through 0b.

In the structure of such a flow cell 20, the flat plate portion 2
0b has a long distance in the longitudinal direction. That is, since the thickness of the liquid layer between 22 and 21 can be made large, a slight change in concentration can be detected and an accurate measured value can be obtained. Further, when the urine sample is introduced from the cylindrical portion 20a to the flat plate portion 20b as indicated by the arrow, since the flat plate portion 20b and the cylindrical portion 20a have the same cross-sectional area, they show a smooth flow and flow into the flat plate portion 20b. There is no fear that air or the like will be mixed in when the sample section 17 is flattened by the bubble layer 16 as described above.
Since it is clearly divided inside and introduced into the flat plate portion 20b,
As in the conventional case, the bubble layer 16 is mixed in the sample compartment 17,
There will be no refraction due to air and inaccurate measurements. Moreover, since the cross-sectional areas are the same, the specimen in one sample compartment 17 does not remain in the flat plate portion 20b,
It is possible to satisfactorily measure the concentration of the sample specimen in each section within the flat plate portion 20b, and it is possible to obtain an extremely accurate measured value.

In addition, the three-way solenoid valve d ₂
A three-way solenoid valve e ₂ , a mixing coil M _2, and a concentration measuring device 7b are provided, a gas injector 5b is connected to the three-way solenoid valve d ₂ , and a glucose is connected to the three-way solenoid valve e _2. A reagent feeder 6b that stores a reagent for measurement is connected. Since the concentration measuring device 7b is for measuring glucose in urine, the maximum absorbance wavelength of glucose in urine is 505 nm, so a green LED close to this
21 (peak wavelength 565 nm) is used.

In addition, a three-way solenoid valve d ₃
Two three-way solenoid valves e ₃ and e ₄ and a mixing coil M ₃
And a concentration measuring device 7c is provided. Because this third feed line 4c is for occult blood measured in urine, the reagent to be introduced becomes two required, the three-way solenoid valve to its e _3, e ₄
Reagent feeders 6c and 6d are connected to the respective.
Since the maximum absorbance wavelength of occult blood in urine is estimated to be 550 to 560 nm, the concentration measuring instrument 7c in this case uses the orange LED 21 having a peak wavelength of 610 nm.

Furthermore, the three-way solenoid valve d
₄ , three three-way solenoid valves e ₅ , e ₆ , e ₇ , a mixing coil M _4, and a concentration measuring device 7d are provided. Since urobilinogen in urine is measured in the fourth supply line 4d, it is necessary to introduce three kinds of reagents for measuring urobilinogen, and for that purpose, the three-way solenoid valves e ₅ , e
_{6, e} are the ₇ reagent charging unit 6e, 6f, 6g are connected. The concentration measuring instrument 7d in this case uses the green LED 21 having a peak wavelength of 565 nm because the maximum absorbance wavelength of urobilinogen in urine is 562 nm.

The concentration measuring instruments 77a, 7b, 7c and 7d are connected to the above-mentioned display device 8, and the display device 8 displays the measured value for each measurement item. still,
The sub-controllers S _{1 to} S ₇ connected to the three-way solenoid valves e _{1 to} e ₇ are connected to and controlled by the main controller 11.

Next, an example of the urine collector V attached to the toilet body 1 described above will be described with reference to FIG. 4, and in FIG.
The urine collecting device V has a urine collecting cylinder 40 which is attached to the horizontal portion 2 of the toilet bowl in a hanging shape, and a pump cylinder 41 which is coaxially attached to the urine collecting cylinder 40 and is integrally screwed to a lower portion thereof. A flange portion 40a protruding outward from the upper end of the urine collecting cylinder 40 is fixed to the horizontal portion 2, and a fixing plate 43 is screwed onto the lower surface of the horizontal portion 2 to fix the urine collecting cylinder 40 to the horizontal portion 2. .

A piston 42 is vertically movable inside the urine collecting cylinder 40 and the pump cylinder 41, and O-rings O ₁ and O are provided between the inner peripheral surface of the urine collecting cylinder 40 and the piston.
₂ is provided to ensure water tightness. Further, the upper portion of the urine collecting cylinder 40 has a slightly wide inner diameter so that a slight gap M is formed between it and the outer peripheral surface of the piston 42. Also, the urine collection cylinder 40
An air hole 49 communicating with the outside is formed at a joint portion between the pump cylinder 41 and the pump cylinder 41, and a discharge port 48 is further formed. Further, a nozzle hole 40c is formed in an upper portion of the urine collecting cylinder 40, and a nozzle 45 capable of ejecting dilution water into the urine collecting cylinder 40 in a spray form is attached in the nozzle hole 40c. Further, guide holes 41c and 41d are formed in the lower end portion of the pump cylinder 41 so as to communicate with the outside. The inside of the urine collection cylinder 40 is a urine collection chamber C, and the inside of the pump cylinder 41 is a pump chamber P.

A piston rod 42b is provided at a lower end portion of the piston 42 in a hanging shape. The piston rod 42b projects into a base frame 51 connected to a lower end portion of the pump cylinder 41 and is disposed in the base frame 51. Is connected to a slide table 53. The slide table 53 can be vertically moved within the base frame 51 by being guided by the pair of guide bars 52, 52.
The left end portion of the slide table 53 in the drawing is a nut portion 53a formed with a female screw. The nut portion 53a has a ball screw shaft 55 having a ball screw formed on the outer peripheral surface thereof.
Are screwed together, and the ball screw shaft 55 is rotatably supported by ball bearings 56, 56.
The upper end portion of the ball screw shaft 55 is connected to a motor shaft 60a of a stepping motor 60 via a joint portion 58 arranged in a motor frame 59. The operation of the stepping motor 60 causes the ball screw shaft 55 to rotate in the forward and reverse directions. When the ball screw shaft 55 rotates, the nut portion 53a moves up and down, and accordingly, the piston rod 42b moves up and down, thereby vertically moving the piston 42 in the urine collection chamber C and the pump chamber P. Has become.

Referring to FIG. 5, the operation of the urine collecting device V having such a structure will be described. When the piston 42 is located on the lower side, the upper portion of the urine collecting cylinder 40 has an opening shape. Urine flows into the urine collecting chamber C of the urine collecting cylinder 40 when the stool operator makes a stool, and urine is stored in the urine collecting chamber C. When the piston 42 moves upward by the operation of the stepping motor 60 in this state, the urine flowing into the urine collection chamber C is pushed by the upper end portion 42a of the piston 42, and most of the urine flows from the horizontal portion 2 to the toilet bowl 1a. Is leaked in. At this time, a slight amount of urine remains in the gap M. Further, when the piston 42 moves up, the electromagnetic valve b with check feces is opened, and the dilution water is introduced from the dilution tank into the pump chamber P through the guide hole 41d. After that, the solenoid valve b with a check valve is closed, and when the piston 42 moves downward again due to the reverse rotation of the stepping motor 60, the dilution water introduced into the pump chamber P is sprayed from the nozzle 45 into the urine collecting chamber C. Is jetted. In this state, the slightly remaining urine in the urine collection chamber and the diluting water are mixed, and the urine is brought into a favorable diluting state.

When the piston 42 moves up again in this state, most of the diluted urine is discharged and the slightly diluted urine is collected in the gap M. By opening the three-way solenoid valve a, the collected diluted urine is introduced into the supply pipe lines 4a, 4b, 4c, 4d by the action of the suction pump 9 as described above. The diluted urine passes through the three-way solenoid valve a, and the feeding lines 4a, 4
After flowing into b, 4c, and 4d, the three-way solenoid valve a is closed, the stepping motor 60 operates again, and the piston 42 moves up and down several times, and when it moves up, the pump chamber P is diluted as described above. When sucking in water and moving downward, the diluted water in the pump chamber P is introduced into the urine collecting chamber C to wash the urine collecting chamber C well, and the preparation for the next urine collection is completed. The cleaning action by the vertical movement of the piston 42 may be performed immediately before the urine is collected, and the stepping motor 60 is operated by the user appropriately turning on the operation switch or the like, and the piston 42 is vertically moved as described above. However, it is also possible to stop after that and issue a signal to indicate that preparation for urine collection is complete.

The urine collected and diluted by the urine collector V in this way is distributed to each of the first feeding pipe 4a to the fourth feeding pipe 4d by opening the three-way solenoid valve a, as described above. , Is branched by the operation of the pump 9, and the concentration is measured for each measurement item.

This three-way solenoid valve a has, for example, a structure as shown in FIG. 9, which is different from the other three-way solenoid valves c and d ₁ to d.
₄ and are an same structure as the e ₁ to e _7, the outer peripheral portion of the main body 13 of the three-way solenoid valve and the electromagnetic coil 14 is disposed, the core 25 inside, is biased spring 26 The plunger 27 is movably arranged, and the valve body 18 is fixed to the tip of the plunger 27. This valve body 18 has three first pipes 1 connected to the main body 13.
9a, the second pipe 19b, and the third pipe 19c can be opened and closed, respectively. In the state shown in the drawing, the first valve body 18 contacts the third pipe 19c and closes the third pipe 19c. In this state, the urine introduced from the first pipe 19a flows into the second pipe 19b, and when the electromagnetic coil 14 is excited and the plunger 27 is moved leftward, the third pipe 19c. Is opened, and at the same time, the first pipe 19a is closed. In this state, the third pipe 19c and the second pipe 19b are in communication with each other,
For example, a reagent or the like is supplied from the third pipe 19c to the second pipe 19b.
The structure is such that it flows into the interior.

After the measurement is completed for each item in each of the feeding pipelines 4a to 4d, the three-way solenoid valve c is opened and the first feeding is performed from the three-way solenoid valve c through the three-way solenoid valve a. Cleaning water flows into the pipes 4a to 4d to clean the insides of the respective supply pipes 4a to 4d.

Next, the three-way solenoid valve c is switched, and instead of the cleaning liquid, air flows from the three-way solenoid valve c through the three-way solenoid valve a to each of the supply pipe lines 4a
Introduced within ~ 4d. This is to form a dividing layer of air between the cleaning liquid layer introduced by introducing air, and the inside of each of the feeding pipelines 4a to 4d is well cleaned with the cleaning liquid, and Due to the divided air layer of the inflowing air, even when new urine, which is the next sample, is introduced into each of the feeding pipelines 4a to 4d, the new sample is not mixed with the cleaning liquid and the next measurement is performed. The structure is such that continuous measurement can be performed at extremely high speed.

Incidentally, in this example, as shown in FIG. 6, each of the feeding pipelines 4a to 4d is configured to be separable into a cartridge type, and each cartridge has a structure as shown in FIG. The solenoid valve, mixing coil and concentration meter are compactly arranged.

For example, the three-way solenoid valve d ₁ , the three-way solenoid valve e ₁ , the mixing coil M ₁ and the concentration measuring device 7a arranged in the first feeding line 4a are incorporated in the protein cartridge 12a. The protein cartridge 12a can be attached and detached along the toilet body 1 by opening the door from the front side of the toilet body 1, and when the protein cartridge 12a is set, the protein in urine can be measured.

In this way, the constituent members in each of the supply pipelines 4b, 4c, 4d are also housed in the respective cartridges, and the glucose cartridge 12b and the occult blood cartridge 12 are included.
The c and urobilinogen cartridges 12d are detachably attachable to the toilet body 1, respectively. The cartridges 12a to 12d may be formed in the vertical direction, and the reagent injectors 6a to 6g for each item may be integrated in each of the cartridges 12a to 12d.

In this example, the reagent injectors 6a to 6g are separate units.
It is configured as an individual reagent tank T, and is configured to be connected to each of the cartridges 12a to 12d.

That is, as shown in FIG. 8, the reagent tank T has seven compartments in this example, and can store different reagents. Each chamber of the reagent tank T has a different capacity. A reagent with a large volume to be added to a urine sample is a chamber with a large volume, and a reagent with a small volume is stored in a narrow chamber. It is a reward.

For example, for the measurement of protein in urine, pyrogallol red, ammonium molybdate, and a surfactant are used as reagents, and the use amount is required at a ratio of 3 to 1 of the urine sample. The chamber 6a of the corresponding reagent tank T has a volume of 3 as a ratio. Also, 6
Mutarotase, which is a reagent for measuring glucose, is contained in b.
A reagent composed of glucose oxidase, aminoantipyrine, etc. is stored, and the volume ratio is 3 because it is necessary at a ratio of 3 to the urine sample 1. or,
6c and 6d are for reagents for measuring occult blood in urine, and two kinds of reagents are required for measuring occult blood. Phenolphthalein reagent is stored in 6c at a volume ratio of 1 and in 6d. The hydrogen peroxide solution is stored at a volume ratio of 1. Further, 6e, 6f and 6g are for reagents for measuring urobilinogen in urine, three kinds of reagents are required, 6e stores ascorbic acid, 6f stores Ehrlich reagent, and 6g stores 6g. Saturated sodium acetate is stored inside. Since 10 parts of ascorbic acid, 1 parts of Ehrlich reagent and 1 parts of saturated sodium acetate are needed for the urine specimen 4.32, the respective chambers are formed in a volume ratio corresponding to the ratio.

In this way, the reagent tank T is integrated and has a chamber having a volume corresponding to the usage amount of each reagent. Therefore, if the reagents are filled in the respective chambers in the reagent tank T, respectively, Since all the reagents are consumed evenly and all the rooms are emptied when the reagent tank T is emptied, it is possible to replenish all the reagents, for example, once a month, etc., and maintenance is very good. Can be done.

If one liquid level sensor such as an ultrasonic sensor or an optical sensor is attached to the reagent tank T somewhere, the remaining amount in the entire room can be easily known.

The reagent tank T can be installed in a concealed manner along the side wall surface of the toilet body 1, and each of the cartridges 12a ...
It can be compactly placed around the toilet bowl together with 12d and can be used in an easy state such as maintenance management.

Next, a second embodiment will be described with reference to FIGS. 11 and 12.

That is, in this example, the reagent charging unit 6a~6g 1 collectively in the first view, also the three-way electromagnetic valve _d 1 ~
d ₄ and e _{1 to} e ₇ and mixing coils M _{1 to} M ₄ are integrated into one, and the concentration measuring instruments 7a to 7d and the suction pump 9 are integrated into _{one and are} divided into stages. It is configured as one analysis unit unit E framed in. The analyzing unit E can be arranged in a concealed manner on the rear side surface side of the toilet body 1 via a cover or the like. In addition, in FIG. 11, B is an operation part, and the urine collector V
Or for operating the three-way solenoid valves a and c and the suction pump 9. As shown in detail in FIG. 12, in the analysis unit E, a reagent feeder having a reagent storage function is arranged in the upper stage, and a three-way solenoid valve and a mixing coil for dividing and stirring the sample are arranged in the middle stage. Since the pump and the concentration measuring instrument that perform the detection and suction functions are installed in the lower stage, all the components can be assembled in a compact space, and good maintenance and management is performed for each function. It is configured to get to.

(Effect of the Invention) The urine component measuring device of the present invention is provided with a three-way solenoid valve connected to the wash water storage tank on the upstream side of the delivery pipe, and controls the three-way solenoid valve to control the inside of the delivery pipe. After the measurement of the urinary components is completed,
Open the three-way valve to flush the wash water from the wash water storage tank into the feed line, and wash the feed line to remove residual liquid such as urine and reagents satisfactorily. This has an effect that the inside of the feeding pipe can be satisfactorily cleaned for measurement, and an accurate measurement value can be obtained for each collected urine.

In addition, after flowing the cleaning water into the supply pipeline, the three-way solenoid valve can be controlled to send air into the supply pipeline, and the cleaning water can be partitioned by the air in the supply pipeline immediately. Next, the collected urine can be sent into the feed line to measure new components in the urine, and at this time, the layer of air sent from the three-way solenoid valve in the feed line causes flush water to flow. The new urine is well separated from the new urine, and the wash water is not mixed into the urine, and the urine component can be continuously and rapidly measured.
