Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a reagent cartridge structure capable of supplying a reagent to a urine collection device attached to a toilet bowl or the like.

(Prior art and its problems) Conventionally, in order to determine the presence of sugar in urine,
A member impregnated with a reagent that can react with sugar, etc. in urine is installed in the toilet bowl, and when urine comes into contact with this member, the reagent and the components in the urine react and develop a color. There are now toilets that can detect the presence of sugar, etc.
Enzyme reagents were insufficiently and incompletely supplied to the coloring components, and the reaction between the reagents and urine was incomplete, making it unreliable to determine the presence of sugar in urine, etc. .

(Means for Solving the Problems) The present invention was devised in view of the above-mentioned conventional problems, and is capable of supplying an enzyme reagent to a urine collection device that can accurately detect the amount of sugar in urine. The purpose is to provide a reagent cartridge structure that can store an enzyme reagent that reacts with components in the urine collected in the urine collection chamber of a urine collection device in order to appropriately supply the enzyme reagent to the urine collection chamber. The structure of the reagent cartridge to be obtained includes a reagent cartridge tank having a reagent introduction port and an air hole that are always sealed with a seal, and an enzyme reagent sealed inside, and a reagent cartridge tank that is removable and has a cartridge case that has a pin member capable of breaking the seal of the drug introduction port of the tank when installed and is placed in communication with the urine collection device; and the case is closed in a predetermined position. and a pin member that can occasionally break the seal of the air hole of the reagent cartridge tank.

(Function) In order to introduce the reagent into the urine collection chamber of the urine collection device, a reagent cartridge tank, a reagent cartridge case, and a pin member are provided. Enzyme reagents that react depending on the concentration are sealed, and the reagent cartridge tank's reagent port and air hole are always sealed with a seal, so the reagent cartridge tank must be stored separately. Furthermore, when the reagent runs out, the reagent cartridge tank can be easily replaced to easily prevent the reagent from running out. In addition, the cartridge case to which the reagent cartridge tank can be attached is equipped with a pin member, and when the reagent cartridge tank is attached to the cartridge case, the pin member seals the introduction port of the reagent cartridge tank. Since the stopper seal is broken, the enzyme reagent in the reagent cartridge tank flows out from the drug guide port, and the enzyme reagent can be supplied from the cartridge case to the urine collection device. Also, the cartridge case is
For example, a pin member is provided on the side of the toilet bowl that can be opened and closed, and when the pin member is closed, it can rotate from the toilet bowl side and break the seal of the air hole of the reagent cartridge tank. When the cartridge case is closed in a predetermined position, the air hole is ruptured by the pin member, and air is introduced into the reagent cartridge tank through the air hole, allowing the enzyme reagent in the reagent cartridge tank to flow smoothly through the reagent introduction port. Supplied to urine collection device.

Next, the structure of the urine collection device 7 is shown in Figures 4 and 5.
This will be explained based on FIGS. 6, 7, and 8.

The urine collection device 7 includes a urine collection cylinder 30, a pump cylinder 31 coaxially connected to the urine collection cylinder 30 and downward, and a piston 3 that is vertically slidable inside the urine collection cylinder 30 and the pump cylinder 31.
2, and the upper end flange 30a formed in a protruding shape at the upper end of the urine collection cylinder 30 is installed almost flush with the upper surface of the third bowl surface 8c in FIGS. 2 and 3. The peripheral edge of the urine collection cylinder 30 below the upper end flange 30a is a threaded portion 30f, and the fixing plate 33 is screwed into this threaded portion 30f from below to connect the upper end flange 30a and the fixing plate 33. The urine collection container 7 is attached to the toilet main body 2 by tightening the wall surface of the third bowl surface 8c.
Fixed.

The inside of the urine collection cylinder 30 is a cylindrical urine collection chamber C, and the wall surface of the urine collection cylinder 30 has an electrode connection port 30b communicating with the urine collection chamber C, a nozzle hole 30c bored at an opposing position, and an electrode. Connection port 30

A nozzle cap 35 is screwed into 0c, a cleaning spray 36 is screwed into the cleaning spray hole 30d from the outside, and a rod-shaped thermistor 37 is fitted into the thermistor hole 30e from the outside.

The oxygen electrode 34 outputs the amount of oxygen consumed as a current value to the outside based on the change in resistance value between the electrodes due to the enzyme consuming oxygen when the enzyme reagent and glucose in urine cause an oxidation reaction. It is something that can be done.

Further, the nozzle cap 35 is formed in the shape shown in FIGS. 8A, 8B, and 8C, with a threaded portion 35b formed on the outer periphery, and a lower portion having a conical surface at the center of the upper surface of the main body 35a. A conical hole 35c is bored, and four diffusion holes 35d, 35d, 35d, 3 widen downward from the bottom side of the conical hole 35c.
5d is drilled.

When liquid flows into the conical hole 35c from the outside, the liquid can be diffused through the four diffusion holes 35d and injected into the urine collection chamber C. In this example, as described later, a reagent or Since the dilution water flows in, the reagent and the dilution water can be sprayed in a diffuse manner into the urine collection chamber C through the diffusion hole 35d.

O-ring grooves 30g and 30h are formed in two stages on the inner circumference of the urine collection cylinder 30, and O-rings O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O-ring O1 and O ring ₁ and 0
O ₂ can be inserted into the tube to ensure liquid tightness between the piston 32 and the inner circumferential wall of the urine collection cylinder 30.

In addition, the O-ring groove 30h of the urine collection cylinder 30
An air hole 39 is bored in the lower part of the piston 32, and when the piston 32 moves up and down inside the urine collection cylinder 30, an O-ring O ₃ fitted on the outer circumference of the piston 32 is inserted through the air hole 39. The air compressed between the O-rings _O2 fitted in the urine collection cylinder 30 is discharged to the outside, and the vertical movement of the piston 32 is smoothed.

In this example, the inner diameter of the upper part of the urine collection cylinder 30 is formed wider than the inner diameter of the lower part, so that when the piston 32 slides to the upper part of the urine collection cylinder 30, the outer circumferential wall of the piston and the urine collection cylinder 30 The structure is such that a gap M is formed between the upper inner circumferential walls.

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. The screw hole 3 drilled in the lower end of the urine collection cylinder 30
It is integrated with the urine collection cylinder 30 by screwing a set screw 38 into Oi from the outside.

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 _O4 are fitted into the rod hole 31e. At the same time, there is a dilution water introduction hole 31c horizontally on the side and a reagent introduction hole 3 opposite thereto.
1d is formed. Further, 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 frame 41 of the urine collection device 7 via the screws 40. It is fixedly installed.

There are two guide bars 4 inside the base frame 41.
2 and 42 are vertically arranged in a fixed manner, and a slide table 43 is installed on these guide bars 42 and 42 so as to be slidable in the vertical direction. A linear bearing 44 is fitted into the sliding portion of the slide table 43 and the guide bar 42 to smooth the vertical movement of the slide table 43. Further, on the left side of the base frame 41, a ball screw shaft 45 having a ball screw threaded thereon is rotatably installed vertically, and its lower and upper parts are supported by ball bearings 46. The upper end of this ball screw shaft 45 protrudes into the inside of a motor frame 49 fixed to the upper surface side of the base frame 41, and the motor shaft 50a of the stepping motor 50 fixed to the upper surface of the motor frame 49 is connected to the ball screw shaft 45. Both are connected to a joint portion 48 facing the upper end of the shaft 45 .

Therefore, when the stepping motor 50 is rotated, the ball screw shaft 45 is rotated via the joint portion 48. Note that a nut portion 43a is formed at the left end of the slide table 43, and since this nut portion 43a and the ball screw shaft 45 are screwed together, as the ball screw shaft 45 rotates, the nut portion 43a is Slide table 43 moves vertically with guide bar 4
It is possible to slide along 2. Therefore,
By moving the slide table 43 up and down, the piston 32 can move up and down within the urine collection cylinder 30 and pump cylinder 31 via the piston rod 32b.

Further, a limit switch 47 is installed on the upper side of the base frame 41, and is configured to detect the rising end of the slide table 43.
The limit switch 47 is electrically connected to the control panel 19.

The piping structure in the urine collection device 7 having such a structure is shown in FIG.

A water conduit pipe _Y1 is connected to the dilution water conduit 31c communicating with the pump chamber P inside the pump cylinder 31, and a water pipe _Y2 and a mixing pipe _Y3 are connected to this water conduit pipe _Y1 in a branched manner. A solenoid valve D ₁ with a check valve is provided on the water pipe Y ₂ side, and the water pipe Y ₂ is communicated with the low tank 6 described above, so that cleaning water can be introduced from the low tank 6. Meanwhile, the mixing tube
Y ₃ is equipped with a solenoid valve D ₃ with a check valve, and the mixing pipe Y ₃
The upper end portion is communicated with a nozzle hole 30c of the urine collection cylinder 30, and a reagent and dilution water can be supplied into the urine collection chamber C through a nozzle cap 35 screwed into the nozzle hole 30c.

In addition, a water conduit pipe _Y4 is connected to the reagent conduit 31d of the pump cylinder 31, and the water conduit pipe _Y4 further branches into a drain pipe _Y5 and a reagent pipe _Y6 , which are connected to the drain pipe _Y5. is equipped with a solenoid valve D ₂ with a check valve, and the drain pipe
Y ₅ communicates with the inside of the bowl 8 of the toilet bowl, and forms a waterway in the bowl 8 that can drain water. On the other hand, the reagent tube Y ₆ is equipped with a solenoid valve D ₄ with a check valve.
The reagent tube _Y6 is communicated with the reagent cartridge tank 21 via a hose 23, and forms a passage through which a reagent can be introduced from the reagent cartridge tank 21.

A water pipe _Y7 is connected to the cleaning spray hole 30d of the urine collection cylinder 30, and _a check valve-equipped electromagnetic valve _D5 is provided in the water pipe _Y7 .
is connected to an external water pipe to form a waterway through which tap water can be introduced from the outside.
The cleaning spray 36 fitted in the urine collection chamber C can spray water in a diffuse manner into the urine collection chamber C.

Further, the thermistor 37 fitted into the thermistor hole 30e of the urine collection cylinder 30 is connected to the control panel 19 via the thermistor cord 37a, and senses the temperature inside the urine collection chamber C and sends an appropriate electrical signal to the control panel 19. It is now possible to output.

Next, FIG. 11 shows an operation panel 51 installed on the wall of the toilet near the toilet bowl 1, and when the user operates this operation panel 51, the urine collection device 7 is installed in the control panel 19. It is operated according to a control program.

That is, a display section 51a that can numerically display the concentration of sugar, etc. in urine is formed in the upper part of the operation panel 51, and is configured with an LED or the like.
Further, below that, a measurement preparation switch E ₁ and a measurement switch E ₂ are installed in parallel, and further below that, a switch E ₃ for replenishing dilution water and a switch E ₄ for replenishing reagents are installed in parallel. Between the switches are indicator lamps L ₁ , L ₂ , L ₃ , L ₄ , consisting of LEDs, etc.
L ₅ and L ₆ are provided.

In this example, glucose oxidase as an enzyme reagent is enclosed in the above-mentioned reagent cartridge tank 21, and this glucose oxidase is an enzyme that oxidizes glucose in urine.

Next, the control contents of the control panel 19 are explained in the first step based on the flow chart shown in FIG.
This will be explained by comparing FIG. 1 and FIG. 7.

That is, the control panel 19 is composed of a microcomputer, and the 15th ROM is stored in the internal ROM.
A control program shown in the figure is stored.

In Fig. 15 A, B, and C, first, when the power plug is turned on (S1), the proximity switch 28 detects the remaining amount of reagent in the reagent cartridge tank 21 (S3), and if there is no remaining amount, To do this, 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 (S2).

Next, when the user presses the preparation switch _E1 on the operation panel 51 (S5), the urine collection device 7 is operated according to the following procedure, but the user presses the dilution water supply switch E1. When ₃ is pressed, control is performed according to the flow chart D, and when reagent supply switch _E4 is pressed, control is performed according to the program E.

Here, we will first explain the flow when the preparation switch E ₁ is pressed. After the preparation switch E ₁ is pressed, when the hand approaches the photoelectric switch detection section 15 provided on the side of the low tank 6, the photoelectric switch is activated. 29 is activated (S6), the rotary solenoid 14 is turned on, and flushing water is supplied into the bowl 8 of the toilet bowl (S7). At the same time, the stepping motor 50 is turned on (S8), and the slide table 4
The piston 32 is raised until it comes into contact with the contact point of the limit switch 47 (S10). At that time, the solenoid valve _D1 shown in FIG. 7 is opened as the stepping motor 50 rotates, and dilution water flows from the low tank 6 into the pump chamber P through the water pipe _Y2 and the water conduit pipe _Y1 (S9). At the same time as the limit switch 47 is turned on, the stepping motor 50 starts reverse rotation and lowers the piston 32 (S11). At that time, solenoid valve D ₁ is closed,
Conversely, the solenoid valve _D3 is opened and the dilution water introduced into the pump chamber P is introduced into the urine collection chamber C through the water conduit _Y1 and the mixing tube _Y3 (S12). After the solenoid valve _D3 is closed, the stepping motor 50 further rotates in the reverse direction, and the piston 32 begins to rise (S13). At that time, the solenoid valve _D1 is opened (S14) and dilution water is again introduced into the pump chamber P via the water pipe _Y2 . When the solenoid valve _D1 is closed, the stepping motor 50 reverses again, and the piston 32 starts to descend (S15).
At the same time, solenoid valve _D2 is opened (S16), and pump chamber P
The flush water inside the toilet bowl passes through the water conduit _Y4 and drains into the bowl part ₈ of the toilet bowl through the drain pipe Y5. When the solenoid valve _D2 is closed, the stepping motor 50 starts to rise again (S17), and at the same time, the solenoid valve _D1 is opened (S18), and the cleaning water flows from the low tank 6 again into the pump chamber P via the water pipe _Y2 . be introduced. When the solenoid valve _D1 is closed, a detection signal from the oxygen electrode 34 installed in the urine collection cylinder 30 is input, and the urine collection chamber C
It is determined whether the oxygen concentration within the tank has reached its initial state (S19). That is, the urine collection chamber C, the pump chamber P,
It is determined whether the mixing pipe Y ₃ , water pipe Y ₂ , water pipe Y ₁ , water pipe Y ₄ , and drain pipe Y ₅ have been cleaned, and if YES, the solenoid valve that was already opened in (S44) D ₅
It is turned OFF, and the supply of tap water to the urine collection chamber C through the water pipe _Y7 is cut off (S20), and cleaning is completed. That is, when the preparation switch _E1 is pressed in (S5), it is checked in steps (S6) to (S20) whether or not the urine collection chamber C, pump chamber P, and the surrounding piping have been sufficiently cleaned. It will be confirmed.

When it is confirmed that sufficient cleaning has been performed, the original operation starts from (S21).

That is, the stepping motor 50 is rotated forward and the piston 32 is raised (S21), and at that time the seventh
The solenoid valve _D1 shown in the figure is the stepping motor 50.
is opened as the pump rotates, and dilution water flows into the pump chamber P from the low tank 6 through the water pipe Y ₂ and the water guide pipe Y ₁ (S22). When the slide table 43 contacts the limit switch 47 (S23), the stepping motor 50 is reversed and the piston 32 begins to descend (S24). At the same time, the solenoid valve _D2 is turned on and opened (S25), and the water in the pump chamber P is discharged into the bowl part 8 of the toilet bowl via the drain pipe _Y5 . After the solenoid valve D ₂ is turned off, when the user sitting on the toilet main body 2 urinates (S26), the urinated urine is blown towards the third bowl surface 8c of the bowl part 8 of the toilet main body 2, Urine flows into the urine collection chamber C of the urine collection cylinder 30, which opens upward to the third bowl surface 8c. That is, since the piston 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, the measurement switch _E2 on the operation panel 51 is turned on.
When this happens (S27), the stepping motor 50 rotates and the piston 32 starts to rise (S31).
However, if the switch _E2 is not pressed 10 minutes after the switch _E1 is pressed (S28), the program returns to the step S8 according to the program C, and the stepping motor 50 is repeatedly operated. After the urine collection device 7 is washed, the process is stopped (S8 to S20). Further, when the preparation switch _E1 is pressed, the lamp _L1 flashes at 0.5 second intervals (S28) and then lights up (S29).

Returning to (S27) again, when the measurement switch _E2 is pressed within the regular time (within 10 minutes), the stepping motor 50 is rotated and the piston 32 is raised (S31), and at that time the solenoid valve _D1 is opened. Then, dilution water is introduced from the low tank 6 into the pump chamber P via the water pipe Y ₂ and the water conduit pipe Y ₁ . After the solenoid valve D ₁ is closed, the stepping motor 50 is reversed and the piston 32 begins to descend (S33), and at the same time the solenoid valve D ₃ is opened (S34), and the dilution water in the pump chamber P flows into the water conduit pipe. It is introduced into the urine collection chamber C via _Y1 and mixing tube _Y3 . Here, the urine present in the urine collection chamber C is diluted with dilution water.

After the solenoid valve _D3 is closed, the stepping motor 50 is rotated in the normal direction again, and the piston 32 starts to rise (S35), and the mixed water of urine and dilution water present in the urine collection chamber C is pumped outside from the upper end. It is discharged into the pot part 8. Therefore, in this state, the mixture of urine and diluted water remains only in the gap M of the urine collection chamber C.

When the piston 32 rises (S35), the solenoid valve _D4 is opened and the reagent is sucked into the pump chamber P from the cartridge tank 21 through the reagent pipe _Y6 and the water guide pipe _Y4 (S35N). After the solenoid valve _D4 is closed, the solenoid valve _D3 is opened (S37), the stepping motor 50 is reversed, and the piston 32 starts moving downward (S36). 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, (S31) to (S37)
In this method, most of the urine collected in urine collection chamber C is diluted and discharged, and then mixed with a reagent. This is because glucose in urine is oxidized well by enzyme reagents, and in this example, the dilution ratio is 30 to 50 parts of reagent to 1 part of urine.
It is set to about. That is, in the past, it was difficult to collect a small amount of urine in the toilet bowl, but with this 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 the urine collection chamber C by (S36) and (S37) becomes point a shown in Fig. 13. In this state, in this example, the measurement is waited for 20 seconds, and the The phenomenon that 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 for about 10 seconds from the oxygen electrode 34 (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, the current value does not change as much as the difference. 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 (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 contrast line shown in Figure 14 is from point b to c in Figure 13.
The measured value of the change in current for 10 seconds at point (S39) is stored in advance in the ROM based on past data, and the speed from point b to point c in Fig. 13 (10 When the horizontal axis is the current change value (ΔA/ΔT) per second, the vertical axis shows the concentration of glucose in the urine, and it is possible to instantly know the concentration of glucose based on the speed input in (S39). I can do it. At that time, thermistor 37 of (S38)
The concentration value corresponding to the temperature value input by
It is calculated in the CPU from the diagram in Figure 4 (S42).
This concentration value is displayed as a number on the display section 51 of the operation panel 51.
a (S48).

Further, when the measurement is completed, a signal is given by an electromagnetic buzzer (S47), and after the display has been displayed for a predetermined time, the measurement lamp _L2 is turned off, and further the lamp _L1 is turned off (S49, S50).

When the glucose concentration is displayed on the display section 51a for a predetermined second, the stepping motor 50 is rotated and the piston 32 is raised (S40), and the mixture of reagent, urine, and dilution water in the urine collection chamber C is poured into the pot. Discharge within 8 days. At that time, solenoid valve _D1 is opened and low tank 6
More diluted water flows into the pump room P through water pipe Y ₂ and water conduit pipe Y _1.
(S41).

Next, the solenoid valve _D5 is turned on, and external tap water is introduced into the urine collection chamber C through the water pipe _Y7 , and the inside of the urine collection chamber C is washed with the tap water (S44). At this time, the stepping motor 50 is rotated and the piston 3
2 is lowered (S45), and at the same time, the solenoid valve _D3 is opened (S46), and the dilution water in the pump chamber P is introduced into the urine collection chamber C. Therefore, water pipe Y ₁ and mixing pipe Y ₃
The inside will be cleaned.

After the solenoid valve _D3 is closed, the stepping motor 50 is reversed again and the piston 32 is raised according to the flowchart B described above (S13).
At the same time, the solenoid valve _D1 is opened (S14), and cleaning water is sucked into the pump chamber P from the low tank 6.
At this time as well, the water conduit _Y1 will be cleaned. When the stepping motor 50 is reversed again, the piston 32 is lowered (S15), and the solenoid valve _D2 is opened (S16), and the cleaning water is drained from the pump chamber P via the water conduit pipe _Y4 and the drain pipe _Y5 . , water pipe Y ₄
and drain pipe _Y5 are cleaned with cleaning water. Thereafter, through (S17), (S18), (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 way, in this example, dilution water is introduced into the pump chamber P as the piston 32 moves up and down,
The diluted water is mixed with the urine collected in the urine collection chamber C to dilute the urine, and the diluted urine is further transferred to the piston 3.
2 is discharged to the outside as the piston 32 rises, and the reagent sucked into the pump chamber P is ejected into the urine collection chamber C with the movement of the piston 32 against the diluted urine slightly left in the gap M. By mixing a large amount of reagent into the urine, the concentration of glucose in the urine due to the oxidation reaction caused by the reagent can be successfully measured and displayed numerically. By passing cleaning water through the pump chamber P and surrounding piping, the pump chamber P and surrounding piping can be thoroughly cleaned and self-cleaned, allowing new measurements to be taken.

Furthermore, when the user presses the dilution water replenishment button E ₃ (S51), the lamp L ₃ flashes (S52), and the D
The processing in the program is performed.

That is, the stepping motor 50 is turned on (S53), the piston 32 is raised until the slide table 43 contacts the limit switch 47 (S55), and at that time the solenoid valve _D1 is opened (S54).
Cleaning water is sucked into the pump chamber P from inside the low tank 6. The stepping motor 50 is reversely rotated again to lower the piston 32 (S56), and at the same time, the solenoid valve _D3 is opened (S57), thereby sending the wash water in the pump chamber P to the urine collection chamber C. The stepping motor 50 is reversely rotated again, causing the piston 32 to rise (S58), and at the same time, the solenoid valve _D1 is opened, allowing cleaning water to flow into the pump chamber P again (S59). Further, as the stepping motor 50 reverses, the piston 32 descends (S60), and at the same time, the solenoid valve _D3 is opened and the pump chamber P is opened.
Washing water is then sent to urine collection chamber C (S61). Repeat this (S58) to (S61) about 5 times (S62)
This removes air bubbles contained in each pipe.

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, solenoid valve _D5 is opened and cleaned with tap water (S64).
Furthermore, by program B (S13) ~ (S20)
The steps up to this point are carried out.

Further, when the user presses the reagent supply switch _E4 , the processing in the program E is performed. That is, this is an operation performed when the reagent cartridge tank 21 is replaced.

At that time, when switch E ₄ is turned on (S65),
The lamp _L4 flashes (S66), the stepping motor 50 rotates and the piston 32 rises (S67),
At this time, the solenoid valve _D4 is turned on (S68), and the reagent is sucked into the pump chamber P. limit switch 47
When is turned on (S69), stepping motor 5
0 is reversed and the piston 32 starts descending (S70), at which time the solenoid valve _D3 is opened (S71), and the reagent is introduced from the pump chamber P into the urine collection chamber C. The stepping motor 50 is reversed again (S72), the piston 32 is raised, and at the same time the solenoid valve _D4 is opened (S73), and the reagent is introduced into the pump chamber P again. When the stepping motor 50 reverses again and the piston 32 descends (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 (S76) to remove air bubbles from the reagent pipes, that is, the reagent pipe _Y6 and the water conduit pipe _Y4 . , and finally the solenoid valve D ₆
It is turned ON (S77), and the reagent in the urine collection chamber C is washed, and the air bubbles in the reagent conduit are completed. After completion, lamp _L4 goes out (S78).

In addition, in this example, the reagent cartridge tank 2
Although an example of measuring the concentration of glucose in urine by sealing glucose oxidase in the reagent cartridge tank 21 has been shown, it is also possible to measure the concentration of bilirubin in urine by sealing bilirubin oxidase in the reagent cartridge tank 21. This makes it effective for health diagnosis of liver disease. Furthermore, in the reagent cartridge tank 21, lactate desidroginase (Lactate
If a reagent whose main component is dehydrogenase is included, the concentration of lactic acid in urine can be measured effectively. Furthermore, reagent cartridge tank 2
By enclosing cholesterol oxidase in 1, 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 also be used. In addition, when using each reagent alone to create a toilet bowl with the function of simultaneously measuring bilirubin, lactate, oil, etc. in addition to glucose in urine, multiple independent urine samplers 7 can be installed in the toilet bowl using independent piping. It is also possible to install the urine collection devices 7 and simultaneously measure the glucose concentration, bilirubin concentration, lactate concentration, and fat and oil concentration from each urine collection device 7.

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 compared to the conventional sliding type solenoid that moves up and down, the rotary solenoid 14 is installed compactly inside the low tank 6. In addition to ensuring sufficient water storage capacity, the quietness of the rotary solenoid 14 can reduce noise during drainage, etc.
Furthermore, since a photoelectric switch 29 using an optical fiber is used to operate the rotary solenoid 14, the photoelectric switch does not protrude into the low tank as in the conventional case, and the sensing unit 15 can be fixedly installed in the low tank in a compact manner. It is possible,
Furthermore, since the fiber does not involve electrical wiring, it can be installed in the water inside the low tank, allowing the photoelectric switch to maintain good operating conditions without causing electrical failures due to moisture in the low tank, unlike conventional methods. .

The shape of the reagent cartridge tank mentioned above is not particularly limited, and the mounting location of the cartridge case to which the reagent cartridge tank can be attached is also not particularly limited, such as on the side of the toilet bowl, etc. The reagent cartridge tank can be installed in a space, and the number and position of the reagent introduction ports and air holes of the reagent cartridge tank are not particularly limited.
