DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a urine detecting device which is applied to a diaper or a nursing care bed, detects urine discharge by an infant or an elderly person in need of nursing, and notifies the urinary detecting device to a surrounding caregiver or the like.

[0002]

2. Description of the Related Art Conventionally, a urine detection system detects that a toddler or an elderly person who needs nursing care (hereinafter referred to as a toddler or the like) has urinated, and notifies the surrounding people of the urination. Various devices have been proposed. In general, the urine detection device includes a detection unit that detects urine, and a notification unit that notifies the surrounding person of the detection of urine by the detection unit.

FIG. 14 is a diagram showing a configuration of a conventional urine detection device, particularly a configuration of a urine detection unit. Urine detector 500
Is placed on the surface or inside of the water absorbing material 500 such as cloth or paper.
A pair of conductive wires 502 and 503 are arranged in parallel at a predetermined interval. The urine detecting section 500 includes the water absorbing material 5
01 is wetted by urine, and the pair of conductive wires 502 and 503
The switch functions as a switch that is turned on when the electrical resistance is lowered and the transistor is turned on. The notification unit 550 connected to the urine detection unit 500 includes conductive lines 502 and 503 formed by urine.
Notification operation such as turning on a notification lamp or sounding a notification buzzer is performed in accordance with the conduction between them.

Since the electrical resistance between the electrodes caused by the wetting of the water-absorbing material 501 by urine is small, it is necessary to apply a voltage between the electrodes in order for the electrical resistance to flow between the electrodes due to the reduced electrical resistance. It is necessary to increase the applied voltage. However, increasing the voltage applied between the electrodes is not preferable because the risk of electric shock increases.

FIG. 15 is a diagram showing a configuration of a urine detecting section 600 having a configuration different from that of the urine detecting section 500 having the above configuration. The urine detecting section 600 is configured to sandwich one end of a water-absorbing material 601 such as cloth or paper with a clip 602 composed of U-shaped conductive wires 602a and 602b. The conductive wire 60
2a and 602b are separated by a water absorbing material 601. The urine detecting section 600 functions as a switch that is turned on when the water-absorbing material 601 is wetted by urine and the electrical resistance between the conductive line 602a and the conductive line 602b is reduced to be conductive. The notification unit 650 connected to the urine detection unit 600 includes a conductive line 602a and a conductive line 602 formed by urine.
According to the conduction during b, a well-known notification operation such as turning on a notification lamp or sounding a notification buzzer is performed.

The urine detecting device having the above structure can be used repeatedly by replacing the water absorbing material 601 and is economical. The clip 602 is arranged in a diaper or a sheet for accommodating the urine detection unit 600 because the clip 602 holds the water absorbing material 601 therebetween. Therefore, when the water absorbing material 601 is wet by urine, the clip 602 is also wet. For the above reasons, it is not preferable from the viewpoint of hygiene to repeatedly use the clip 602. Further, it is inconvenient to disinfect the clip 602 every time the water absorbing material 601 is replaced.

The clip 602 needs to have a certain degree of hardness and size in order to sandwich the water absorbing material 601. However, the hardness and size of the clip 602 deteriorate the skin contact in actual use. It becomes a factor. If the size of the clip 602 is reduced in order to solve the problem of contact with the skin, the distance L from the clip 602 to the end of the water absorbing material 601 becomes longer, which causes a problem that urine detection sensitivity is reduced.

Further, as in the case of the urine detecting section 500, in order for electricity to flow between the conductive lines 602a and 602b due to a decrease in electric resistance of the water absorbing material 601 due to urine, a voltage must be applied between the electrodes. It is necessary to increase the applied voltage. Increasing the voltage applied between the electrodes is not preferable because the risk of electric shock for an infant or the like increases.

The present invention provides a more sensitive urine detection unit (urine detection switch) with good skin contact and low risk of electric shock.
And to provide a urine notification device including the urine detection unit.

[0010]

A urine detection switch according to the present invention comprises a water-absorbing overlay having insulating properties in a dry state, an underlay having insulating properties in a dry state, and insulating property in a dry state.
A pair of electrodes in a non-contact state bonded so as to be sandwiched between the overlay and the underlay with an adhesive having a means for increasing electric conductivity when absorbing water, and at least a part between the pair of electrodes Wherein the adhesive is interposed.

[0011] The method of manufacturing the urine detection switch of the present invention is as follows.
A water-absorbing overlay showing insulation in a dry state, and an underlay showing insulation in a dry state, exhibiting insulation in a dry state, and using an adhesive having a means for increasing conductivity when absorbing water, It is characterized in that a pair of electrodes in a non-contact state is sandwiched between an overlay and an underlay, and the adhesive is interposed at least partially between the pair of electrodes.

DESCRIPTION OF THE PREFERRED EMBODIMENTS (1) First Embodiment FIG. 1 is a diagram showing an entire configuration of a urine detecting device 100 according to a first embodiment. The urine detection device 100 includes a urine detection unit 10 that functions as a switch that is turned on by detecting urine, and a notification unit 21 that performs a notification operation in response to the detection of urine by the urine detection unit 10. .

The urine detecting section 10 and the notifying section 21 are connected by connectors 3 and 20. Connectors 3 and 20 are
Any type of two-wire connector may be used as long as it is detachable. By employing this configuration, only the urine detection unit 10 can be replaced. However,
The connector 3 on the urine detection unit 10 side is provided at a position separated from the urine detection unit 10 main body. This prevents the connector 3 from being stained during actual use, and allows only the urine detection unit 10 to be replaced in a sanitary manner.

As will be described in detail later, the urine detecting section 10
Is one of the means to increase the conductivity during water absorption,
In order to contain the electrolyte, for example, a salt solution having a predetermined concentration is sprayed, or two thin conductive wires sandwiched in parallel with paper immersed in a salt solution having a predetermined concentration are dried. This configuration ensures that electricity flows between the electrodes when wet with urine, and improves the urine detection performance compared to sandwiching the electrodes with a water-absorbing material without any pretreatment. In addition, the voltage applied between the electrodes can be set low.

As means for increasing the electric conductivity when absorbing water, in addition to the above, the paper holding the pair of electrodes may be made to have an insulating property in a dry state while increasing the electric conductivity when absorbing water. In addition, it is conceivable that a granular or powdery conductor is contained therein.

The notification unit 21 includes a power supply 22 and a light-emitting diode 23 in which three AA batteries are connected in series. The positive terminal of the power supply 22 is connected to the conductive line 2a of the urine detecting unit 10 via the connectors 20 and 3. The negative terminal of the power supply 22 is connected to the cathode of the light emitting diode 23. The anode of the light emitting diode 23 is connected to the connector 2
It is connected to the conductive line 2b of the urine detecting unit 10 via 0 and 3. When the urine detection unit 10 detects urine and switches on, that is, when electricity flows between the conductive line 2a and the conductive line 2b, the light emitting diode 23 emits light. It is preferable that the power supply 22 supplies a lower voltage as long as power required for light emission of the light emitting diode 23 is obtained.

Hereinafter, a method of manufacturing the urine detecting section 10 will be described. FIG. 2 is a perspective view for explaining a manufacturing process of the urine detecting unit 10. FIG. 3 is a diagram showing a flow of a manufacturing process of the urine detecting unit 10.

First, an underlay 1 of a predetermined size is placed on a predetermined table.
Is installed (step S1). The underlay 1 may be a water-absorbing material such as paper or cloth, or may be a water-repellent material such as vinyl. However, the underlay 1 is hardly soluble in water, has an electrical insulating property in a dry state, and is flexible. Is good.

On the underlay 1, preferably 0.3 mm
In the following, flexible thin conductive wires 2a and 2b are wired in parallel at a predetermined interval (for example, about 5 cm) (step S).
2). It is preferable to use a wire having a thin insulating film, for example, an enameled wire for the conductive wires 2a and 2b, and to peel off the insulating film at a position located on the underlay 1 from the viewpoint of preventing a short circuit. . In addition, the conductive wires 2a, 2
As b, a thin tape-shaped conductive plate, for example, an aluminum foil may be used.

After the wiring, an overlay 4 used as an overlay member is put on the underlay 1 and adhered to the underlay 1 (step S).
3). The upper paper 4 is rich in water absorbency, hardly soluble in water,
It is preferable that the material has electrical insulation properties in a dry state and has a good touch against the skin. Further, as the overlay member, other material such as cloth having the above characteristics may be used instead of paper. The bonding between the top paper 4 and the underlayment 1 is performed using an adhesive that is water-soluble and has an electrical insulating property when dried.

An electrolyte solution is sprayed on the top paper 4 (step S4). As the electrolyte solution, for example, 18%
A saline solution (NaCl) having the above concentration, preferably a saturated saline solution is used. In addition to the salt solution, the electrolyte solution preferably contains an anion that is less oxidizable than chlorine. In step S4, the underlay 1 and the top paper 4 may be soaked in a saturated saline solution.

After the processing in step S4, the whole is dried in a drying chamber (step S5). Through the above processing, the urine detecting unit 10 is formed.

It should be noted that due to the compatibility between the underlay 1 and the top paper 4,
If the upper paper 4 adheres to the underlay 1 by the processing of steps S4 and S5 without using an adhesive, in step S3, only the upper paper 4 is put on the underlay 1, and these are not bonded. Is also good.

Further, instead of the underlay 1 and the top paper 4, one sheet having a water absorbing property is folded in two, and the pair of conductive wires 2a and 2b are sandwiched (adhered if necessary). After the sheet is impregnated with the electrolyte solution, the sheet may be dried.

As a means for increasing the electrical conductivity when absorbing water, as described above, instead of drying the paper after impregnating the paper 4 with the saline, the water-soluble adhesive in which the salt is dissolved or mixed is mixed. It is also conceivable to use agents.

Further, the upper paper 4 impregnated with the electrolyte solution
Instead, as an overlay member containing an electrolyte, for example, acrylic acid (CH ₂ = COOH) is used as a raw material, and -C
A sheet containing high water-absorbing fiber (for example, “Belle Oasis” manufactured by Kanebo Gosen Co., Ltd.), which contains OONa and has recently begun to be used for a urine receiving portion of a disposable diaper, may be used. In this case, it is possible to increase the sensitivity of the urine detection unit 10 and effectively prevent urine from leaking out of the diaper. The same applies to the urine detection unit 10 'described later, the urine detection unit 301 according to the second embodiment, and the urine detection unit 401 according to the third embodiment.

As described above, the conductive wires 2a, 2b are sandwiched by the water-absorbing material which has been pretreated so as to exhibit good conductivity by being wetted by urine.
The voltage to be applied during b can be set lower.

However, if the voltage applied between the conductive lines 2a and 2b is too low, the light emitting diode 23 used as the notification means may not emit light to the extent that the surroundings can be recognized.

The notification unit 31 shown in FIG. 4 is an example of a unit that allows the power supply voltage to be set lower while maintaining or improving the light emission amount of the light emitting diode. Notification unit 31
Is a low-voltage circuit that closes when electricity flows between the conductive lines 2a and 2b of the urine detection unit 10, and a notification circuit that amplifies the current flowing through the circuit and causes the light-emitting diode 33 to emit light by the amplified current. Be composed. In the low-voltage circuit, a power supply 32 in which two AA batteries are connected in series is used as a lower voltage supply source. The negative terminal of the power supply 32 is connected to the base terminal of the transistor 33. The positive terminal of the power supply 32 is connected to the conductive line 2a of the urine detecting unit 10 via the connectors 30 and 3. On the other hand, the urine detecting unit 10
Is connected to the collector terminal of the transistor 33 and to the cathode of the light emitting diode 33. The positive terminal of the power supply 34 is connected to the anode of the light emitting diode 33. The negative terminal of the power supply 34 is connected to the emitter terminal of the transistor 33.

In the notifying section 31 having the above configuration, the urine detecting section 10
When urine is detected, that is, the conductive wires 2a, 2
b, when the current flows between the transistors 3 b
3 is amplified, and the light emitting diode 33 emits light by the amplified current.

It is. The connectors 3 and 4 are connected to the conductive wires 2a of the urine detecting section 10.
The wiring connected via 0 is grounded in the notification unit 41. In this configuration, the voltage V1 is
It descends as the wetness of the water increases.

The remaining input terminals of the comparator 45 are connected to a three-state switch 44. The three connection terminals of the changeover switch 44 are formed by connecting resistances r3 to r6 in series, a power supply voltage Vcc is applied to one terminal 43, and each node n1 of a resistance division circuit whose other end is grounded.
To n3. By switching the changeover switch 44, by connecting to terminals extending from nodes n1, n2, n3, turn low value the value of the reference voltage V2 (hereinafter, sequentially represented as V2 _n1, V2 _n2, V2 _n3 the reference voltage. ) Can be set. The reference voltages V2 _n1 , V2 _n2 , V2
_n3 is set to a value specified corresponding to the amount of decrease in the voltage V1 when the amount of urination is small, normal, and large.

The comparator 45 determines that the value of the voltage V1 is
The trigger signal Tr1 is output when the reference voltage V2 decreases to the same value as the reference voltage V2 as the wetness of 0 increases.

The transmitter 46 transmits a notification start signal in response to the input of the trigger signal Tr1. The receiver 47 receives a notification start signal from the transmitter 46 for a predetermined time,
A notification operation such as turning on a lamp or sounding a buzzer is performed.

FIG. 6 is a diagram showing an embodiment of a notification unit different from the above. The notification unit 51 includes a detection circuit 58 that detects that the voltage V3 applied to the urine detection unit 10 has started to decrease due to urination of the user. The detection circuit 58 activates the signal processing unit 55 when detecting that the voltage V3 has started to decrease. By employing this configuration, power consumption is reduced.

By switching the connection of the switch 54 to the upper terminal, the center terminal, and the lower terminal in the figure, the reference voltage V4 having a lower value is set in order. The reference voltage V4 is the voltage V when the amount of urination is small, normal, or large.
3 is set to a value specified corresponding to the amount of descent. The signal processing unit 55 outputs the voltage V3 applied to the urine detection unit 10.
And the reference voltage V4, and when the voltage V3 becomes equal to or lower than the voltage V4, a trigger signal Tr for activating the transmitting unit 56
3 is output. The transmitter 56 transmits a notification start signal in response to the input of the trigger signal Tr3. The receiver 57 performs a notification operation such as turning on a lamp or sounding a buzzer for a predetermined time in response to receiving the notification start signal from the transmitter 56.

Hereinafter, the configuration of the notification unit 51 including the wiring in the detection circuit 58 will be described. The wiring connected to the conductive wire 2b of the urine detection unit 10 via the connectors 3 and 50
In the notification unit 51, the power supply voltage Vcc is output via the resistor r10.
Is connected to the terminal 52 to which
Is connected to the signal processing unit 55 via the. Terminal 52
Are connected to the emitter electrode of the P-channel transistor 53. The collector electrode of the transistor 53 is connected to the signal processing unit 55. The resistor r10 is connected between the emitter and the base electrode. The wiring connected to the conductive wire 2a of the urine detection unit 10 via the connectors 3 and 50 is grounded in the notification unit 51.

When the urine detecting unit 10 becomes wet with urine, the voltage V3 applied to the signal processing unit 55 via the resistor r12 decreases. When the voltage V3 falls below the threshold voltage of the P-channel transistor 53, the transistor 53 is turned on, and the trigger signal Tr2 is output.

FIG. 7 is a flowchart showing the processing executed by the signal processing unit 55 activated in response to the input of the trigger signal Tr2. First, the process waits for the input of the trigger Tr2 (NO in step S10). During this time, the signal processing unit 55 suspends functions other than the function of detecting the input of the trigger Tr2. When the trigger Tr2 is input (YES in step S10), the signal processing unit 55 is activated (step S11), and compares the voltage V3 with the reference voltage V4 (step S12). It waits for the voltage V3 to drop to the reference voltage V4 (NO in step S13). When the voltage V3 drops below the reference voltage V4 (Step S
13), the transmitter 56 is required to perform the notification operation.
Is output (step S14), and the process ends.

(2) Usage Example 1 Hereinafter, an example in which the urine detection device 100 is applied to a disposable paper diaper will be described. FIG. 8A shows a urine detection device 100.
FIG. 7B is a diagram illustrating an actual use state of the disposable diaper 150 in which the urine detecting unit 10 is disposed between the groins.
FIG. 3 is a diagram showing a state before assembly. As shown in FIG. 8A, the urine detecting unit 10 is embedded at the crotch position of the diaper 150 such that the connector 3 comes behind the paper diaper 150. In addition, the urine detecting unit 10 includes a disposable diaper 150.
It is preferable to embed it inside during the production of Notification unit 21
The connector 3 connected to the connector 21 is a disposable diaper 1
It is provided at a position distant from 50, that is, at a position not wet even when urinating. By providing the connector 3 at a position away from the disposable diaper 150, the connector 3 is prevented from being stained with urine during actual use, and the urine detecting unit 10 is always kept clean.
Can be exchanged. In addition, it is possible to prevent the connector 3 from directly touching the skin during use and deteriorating the usability.

As shown in FIG. 8B, the length of the disposable diaper 150 before assembly is 50 cm and the minimum width of the crotch portion is 20.
cm, urine detector 1 with a size of 10cm x 30cm
0 is used. As described above, the upper paper 4 of the urine detection unit 10
Although has an electrical insulation property in a dry state, it is pre-treated so as to have a high dielectric constant when wet, so that the voltage applied between the conductive lines 2a and 2b can be set lower. This can effectively prevent the user of the diaper from being electrocuted.

(3) Use Example 2 FIG. 9 shows a case where a urine detecting section 10 ′ having a size larger than that of the urine detecting section 10 is provided at a position where a crotch of a user of the care bed 200 is located. The urine detection unit 10 '
A 100 cm × 50 cm size is adopted. The size may be changed according to the size of the care bed 200. The connector 3 ′ of the urine detection unit 10 ′ is connected to the connector 20 of the notification unit 21.

In the case of the urine detection section 10 ', since the detection range is wide, the conductive wires 2a and 2b are wired in parallel and spirally as shown in the figure. Note that the wiring shape of the conductive lines 20a and 2b is not limited to the above-mentioned spiral shape, and may be provided so as to be parallel and obliquely cross the detection range, and other appropriate shapes may be adopted. The detecting unit 10 ′ has electrical insulation in a dry state, but has a conductive material 2 a and a conductive wire 2 a made of a water-absorbing material that has been pre-treated so as to increase the dielectric constant when wet.
This is because b is sandwiched.

The urine detecting section 10 ′ is provided with a connector 3 ′ at a position hardly wet by urination, for example, outside the sheet 201. Thereby, it is possible to cleanly replace the urine detection unit 10 'without polluting the urine detecting unit 10' at the time of urination.

It is characterized by adoption. By employing this configuration, the number of components can be reduced and cost can be reduced.

Note that, as shown in FIG.
a and 303b may be inserted into the sheet 302 in a wave-stitched manner.

Further, as shown in FIG.
For a and 303b, a configuration may be adopted in which conductive wires 303a and 303b are attached to one surface of the sheet 302 or alternate surfaces. In this example, flat conductive tapes 303a and 303b are used as the conductive wires 303a and 303b so as to be easily attached to the sheet 302.

(5) Third Embodiment FIG. 13 is a diagram showing a configuration of a urine detecting section 401 of a urine detecting device 400 according to a third embodiment. The configuration of the urine detection device 400 other than the urine detection unit 401 is the same as that of the urine detection device 100 described in the first embodiment, and a duplicate description thereof will be omitted.

The urine detecting section 401 has an insulating property and a water absorbing property in a dry state, and has an insole member 404 containing an electrolyte for enhancing the electric conductivity at the time of water absorption, and a pair of conductive wires 405a and 405b. It is characterized in that a part is sandwiched between an overlying member 402 and an underlying member 403 having water permeability. The overlay member 402 and the underlay member 403 are bonded together along an edge region 406 indicated by oblique lines in the drawing.

The overlay member 402 and the underlay member 40
In place of 3, one sheet having water permeability is folded in two, and the insole member 404 and the pair of conductive wires 40
A part of 5a, 405b may be wrapped.

The insole member 4 containing the electrolyte described above
As 04, absorbent cotton or the like, which is immersed in a saline solution (NaCl) and then dried, can be mentioned. In addition, as the member 404, acrylic acid (CH ₂ = COOH) is used as a raw material, and -COON
It is conceivable to use a highly water-absorbent resin (for example, “Aquapearl” manufactured by Mitsubishi Kagaku Co., Ltd.) which has been used for urine receiving portions of disposable diapers in recent years. In this case, the sensitivity of the urine detection unit 401 can be increased, and leakage of urine can be effectively prevented by using the characteristics of the superabsorbent substance.

As long as the conductive wires 405a and 405b are configured to easily conduct when the insole member 404 is wet with urine, the conductive wires 405a and 405b may be inserted into the insole member 404 as shown in FIG. It is good, and it may be made to stick on either one side or alternate sides.
