The flow rate of the cleaning water sprayed from the butt nozzle 104 is set to 4.68 l / min, and the average flow velocity is set to 0.012 m / s.

The stool nozzle 105 is a nozzle for performing a process (hereinafter, referred to as a stool crushing process) that mainly pushes the stool from the waste channel 101 toward the discharge unit 102 while finely crushing the stool by the jet water pressure of the washing water. It is. The stool nozzle 105 is provided on the bottom side of the filth channel 101 below the butt nozzle 104. The stool nozzle 105 has a plurality of stool crushing injection holes 105a so that the injection direction is the bottom surface of the filth channel 101 and directly below the anus of the human body where stool collects most easily. The injection hole 105a for stool pulverization has an injection hole diameter toward the center in order to maximize the injection pressure of the washing water injected toward the center of the filth flow path 101, where the stool is most likely to accumulate. Is configured to gradually increase. With this configuration, the stool accumulated in the center of the filth channel 101 is crushed first, and a channel through which the washing water flows toward the discharge unit 102 is secured. Therefore, in the initial stage where the washing water starts to be ejected from the stool nozzle 105, it is possible to prevent a problem that the washing water bounced off by the stool and blocked is overflowed from the filth channel 101. The flow rate of the washing water sprayed from the stool nozzle 105 is set to 4.8 l / min, and the average flow velocity is set to 0.013 m / s.

As shown in FIG. 4, the sensor cleaning hole 105 b is configured such that its injection direction faces a light receiving portion 107 of an infrared sensor (described later) provided in the vicinity of the discharge portion 102. With this configuration, the sensor cleaning hole 105b, after finishing the stool pulverization process in addition to the stool pulverization process, sprays cleaning water onto the light receiving unit 107 disposed at the opposite position to clean the surface of the sensor cleaning hole 105b. It becomes possible to prevent malfunction of the sensor.

  The bidet nozzle 202 shown in FIG. 8 is a nozzle for cleaning excrement adhering to the genital area of the human body as a main injection range, and can clean the genital area regardless of gender or body type. Thus, it has a narrow and vertically long shape. The bidet nozzle 202 has a plurality of bidet injection holes 202a such that the injection direction faces the patient's genital area. The bidet injection hole 202a has a smaller hole diameter and a larger number of holes than the butt injection hole 104a of the butt nozzle 104 and the stool crushing injection hole 105a of the stool nozzle 105. By adopting such a configuration, it is possible to moderately suppress the spray pressure of the cleaning water while performing a wide range of cleaning, and it is possible to perform soft cleaning particularly on the sensitive shadows in the human body. The bidet nozzle 202 has a plurality of urine treatment injection holes 202b so as to surround the entire side portion in order to wash urine scattered in the diaper casing A. The flow rate of the cleaning water sprayed from the bidet nozzle 202 is set to 4.68 l / min, and the average flow velocity is set to 0.010 m / s.

  As shown in FIG. 9, the anus nozzle 203 is a nozzle for washing excrement adhering to the patient's anus and around the anus as an injection range, and has a plurality of anal central injection holes arranged in the center thereof. 203a, and a plurality of anal peripheral injection holes 203b disposed on both side surfaces of the central anal injection hole 203a. The anal central injection hole 203a is configured such that the injection direction is directed toward the patient's anus, and the anus peripheral injection hole 203b is configured such that the injection direction is directed toward the periphery of the anus. The diameter of the central anal hole 203a is larger than that of the peripheral anal hole 203b, and is substantially the same as the diameter of the stool pulverizing injection hole 105a and the butt injection hole 104a. By adopting such a configuration, it becomes possible to increase the injection pressure of the washing water injected from the central anal hole 203a and to wash deep into the anus of the human body. On the other hand, it is possible to moderately suppress the spraying pressure of the cleaning water sprayed from the anus peripheral spray hole 203b, and soft cleaning can be performed especially around the delicate anus in the human body. The flow rate of the washing water sprayed from the anal nozzle 203 is set to 4.8 l / min, and the average flow velocity is set to 0.019 m / s.

  In order to enable more effective cleaning, an orifice structure may be employed for the fecal crushing injection hole 105a and the anal central injection hole 203a. By adopting the orifice structure, it is possible to widen the spray range of the cleaning water, and it is possible to clean a wide range of the human body while suppressing the amount of the cleaning water.

  The various nozzles 104, 105, 202, and 203 are supplied with air as well as cleaning water from the main body C via the various nozzle tubes 602, 603, 604, and 605. That is, after each part of the patient is washed with washing water, air is blown to dry the parts. As shown in FIG. 4, when air is supplied into the diaper casing A from the various nozzles 104, 105, 202, 203, a vent hole 112 for allowing the air to escape from the diaper casing A to the outside air rises. It is pierced at a predetermined location of the portion 200.

  The configuration of the various sensors 106, 107, 108, 109 will be described in detail. As shown in FIG. 4, the diaper casing A is provided with a light emitting portion 106 of an infrared sensor at an end of the filth channel 101 opposite to the discharge portion 102, and above the front edge of the discharge portion 102. A light receiving portion 107 of an infrared sensor is disposed, and a receiving portion 108 of an infrared sensor is disposed adjacent to the light emitting portion 106. The light emitting unit 106, the light receiving unit 107, and the receiving unit 108 function as a stool detection sensor G that detects stool in the filth channel 101. The diaper-shaped casing A is further provided with a urine detection sensor H for detecting urine on the bottom of the filth storage space s.

  The stool detection sensor G has stool between the light emitting unit 106 and the light receiving unit 107, that is, in the filth channel 101, based on whether or not the infrared light transmitted from the light emitting unit 106 is received by the opposing light receiving unit 107. Whether or not is detected. The light receiving unit 107 is installed on the upper part of the discharge unit 102 where ambient light is difficult to reach in order to prevent malfunction due to ambient light other than infrared rays.

By the way, when the patient uses the diaper-shaped casing A on a bed having a high cushioning property, the diaper-shaped casing A may be recessed by being pressed by the patient's own weight, and the filth channel 101 may be inclined. . In such a case, cleaning in the diaper-shaped casing A and suction of excrement are insufficient, and the light emitting unit 106 sinks into the cleaning water remaining in the filth channel 101, and infrared light does not reach the light receiving unit 107. . As a result, since the stool detection sensor G detects a stool, the diaper casing A malfunctions.

  Therefore, in order to prevent such a malfunction, the stool detection sensor G includes a receiving unit 108 in the vicinity of the light emitting unit 106 for detecting the inclination of the diaper casing A, as shown in FIG. The receiving unit 108 is provided adjacent to the light emitting unit 106 and can detect infrared rays transmitted from the light emitting unit 106 to the side, but when the light emitting unit 106 and the receiving unit 108 are submerged, the infrared rays are transmitted. It cannot be detected.

Therefore, the stool detection sensor G is inclined to the diaper-shaped casing A when the light emitting unit 106 sinks into the washing water remaining in the filth channel 101 and neither the light receiving unit 107 nor the receiving unit 108 receives infrared rays. It is the structure which can detect that has occurred. When the stool detection sensor G detects that the diaper casing A is tilted, the stool detection sensor G displays an error on a display unit (not shown) provided in the main body C, and the main body C has all functions. To stop. In addition, when the situation where the diaper-shaped casing A inclines cannot generate | occur | produces, it is good also as a structure which does not provide the receiving part 108 but performs stool detection only by the light emission part 106 and the light-receiving part 107.

  As shown in FIG. 4, the urine detection sensor H includes a pair of electrode pins 109 and 109 that are disposed adjacent to each other in the front-rear direction. The electrode pins 109 and 109 are connected to the main body C via a conductive wire (not shown), and are set so that a weak current flows from the main body C to one of the electrode pins 109. And the urine detection sensor H becomes a structure which detects the electric current value at the time of energizing washing water or a urine as a conductor with the weak electric current which the electrode pins 109 and 109 apply.

Here, in general, since there is a difference in salinity between washing water and urine, there is a difference in electrical conductivity, and the current value detected by the urine detection sensor H is different between washing water and urine. . FIG. 10A shows experimental results of measuring current values for various types of water that can be used as washing water using the urine detection sensor H, and FIG. 10B shows an arbitrarily selected subject (A). It is the experimental result which measured the electric current value about the urine of (E). The urine sensor output value is a current value converted into a voltage value using an A / D converter. For example, in FIG. 10B, “urine (A)” indicates the result of measuring the urine of the subject (A).

As is clear from FIG. 10, urine has a higher salinity than water, and it is confirmed that there is a large difference in the urinary sensor output values corresponding to the difference in salinity. Therefore, the current value between the electrode pins 109 and 109 is detected by the urine detection sensor H, and for example, the threshold value of 2.0 V is used for the urine sensor output value, so that the washing water and the urine are reliably discriminated. It becomes possible to do.

  The electrode pins 109 and 109 are configured so that the surfaces thereof are gold-plated to prevent corrosion, and the positive and negative poles of the voltage applied to one of the electrode pins 109 are crossed. With such a configuration, it is possible to prevent a problem that only one of the electrode pins 109 is oxidized and corroded, or a detection accuracy is deteriorated due to adhesion of foreign matter.

  With such a configuration, when the patient defecates and / or urinates, the diaper casing A detects stool and / or urine with the stool detection sensor G and / or urine detection sensor H, and the detection signal is sent to the main body C. And send. The main body C that has received the detection signal supplies cleaning water to the various nozzle pipes 602, 603, 604, and 605, and the cleaning water is injected into the diaper casing A from each of the various nozzles 104, 105, 202, and 203. Is done. This cleanses the patient's buttocks, pubic area and anus while allowing stool and / or urine to flow towards the drainage section 102. Thus, after finishing the cleaning process of cleaning each part of the patient and the inside of the diaper casing A, the main body C drains the water by sucking the cleaning water remaining in the various nozzle tubes 602, 603, 604, 605. Then, a drying process is performed in which air is supplied to the various nozzle tubes 602, 603, 604, and 605 to dry the buttocks, pubic area, and anus of the patient.

The main body C will be described. As shown in FIG. 1, the main body C receives the excrement storage part D that stores the filth of the diaper-shaped casing A, and the detection signal of defecation and / or urination from the diaper-shaped casing A, and the subsequent washing operation The apparatus control part F which performs various operations, such as these, and the washing water supply part E which supplies washing water to the diaper-shaped casing A are provided.

If they are not connected after satisfying the directionality, they do not fit well. Therefore, when these do not fit well, the tank lid 304 is in a loosened state with respect to the filth storage tank 300, etc., so that the sealed state in the filth storage tank 300 is not secured. Yes.

On the upper part of the tank lid 304, a fixing bracket 310 for fixing the hose connecting portion 303 to the tank lid 304 is installed. Both ends of the fixing bracket 310 are rotatably installed on the tank lid 304, and the fixing bracket 310 is raised with the hose connecting portion 303 connected to the tank lid 304, and the upper portion of the hose connecting portion 303 is placed on the tank. It is comprised so that it can fix by pressing to the cover body 304. FIG.

As shown in FIG. 15, a housing 307 is installed on the upper portion of the hose connecting portion 303, and a pair of electrode pins 308 and 308 are fixedly supported on the housing 307 at a predetermined interval. The electrode pins 308 and 308 are connected to a pair of signal lines 309 and 309, and the signal lines 309 and 309 are connected to a control circuit (not shown) in the main body C, and the signal line 309 is connected from the control circuit. , 309 is set so that a current flows through one of them.

On the other hand, as shown in FIG. 14, in a state where the hose connecting portion 303 is inserted and connected to the tank lid 304, the inner lids 305 and 305 are in the form of an open lid in a suspended state. With such a configuration, when the filth storage tank 300 is removed from the main body C and the filth is discarded, the internal lid 305 at the opening of the tank lid 304 can be removed even if the hose coupling portion 303 is removed from the filth storage tank 300. Since the lid is automatically closed by 305, the odor of filth in the filth storage tank 300 and the filth itself do not flow out to the outside, and the filth storage tank 300 can be safely carried. After the filth storage tank 300 is carried to a predetermined location, the tank lid 304 is removed, and the filth is discarded from the upper outlet of the filth storage tank 300.

Further, as shown in FIG. 15, an intake pipe 401 a is connected to the hose connecting portion 303 so as to be adjacent to the filth inflow pipe 103. As shown in FIG. 1, the filth storage tank 300 is connected to the apparatus control unit F through an intake pipe 401a. Inside the filth storage tank 300, air is sucked through the intake pipe 401a by the operation of the suction pump 400 in the apparatus control unit F described later, and a negative pressure state is formed. The filth is diaper-shaped through the filth inflow pipe 103. The casing A can be sucked.

  As shown in FIG. 1, the cleaning water supply unit E includes a raw water tank 500 for supplying raw water as cleaning water, a hot water tank 501 for heating the cleaning water supplied into the diaper casing A to a predetermined temperature, A solenoid valve 503 for controlling water supply from the raw water tank 500 to the hot water tank 501 is provided. The hot water tank 501 includes a pipe heater 502 that heats the raw water supplied from the raw water tank 500 via the solenoid valve 503, a water level sensor 505 that detects the water level, and a temperature sensor 506 that detects the water temperature. When the water level sensor 505 detects that the water level in the hot water tank 501 is in a state that requires water supply, the cleaning water supply unit E opens the solenoid valve 503 to supply a predetermined amount of raw water from the raw water tank 500 to the hot water tank 501. When the water level sensor 505 detects that the hot water tank 501 is filled with raw water and reaches a predetermined water level, the solenoid valve 503 is closed based on the detection signal of the water level sensor 505 to cut off the raw water supply.

The washing water supply unit E detects the temperature of the raw water in the hot water tank 501 with the temperature sensor 506 and maintains the raw water with the tube heater 502 so that the patient maintains the temperature set via a temperature control circuit (not shown). Heat to warm water. With this configuration, when performing a cleaning process in which warm water in the hot water tank 501 is fed into the diaper casing A as cleaning water, the patient is always supplied with the appropriate temperature of cleaning water, so that the patient can use it well. The state can be obtained. The outlet provided on the bottom side surface of the hot water tank 501 is connected to the apparatus control unit F through a water supply pipe 504a, and the cleaning water heated in the hot water tank 501 through the water supply pipe 504a is supplied to the apparatus control unit. F is supplied. In addition, instead of the solenoid valve 503, a raw valve supply from the raw water tank 500 to the hot water tank 501 may be adjusted by a mechanical operation using a float valve or the like.

  As described above, the device control unit F is connected to the excrement storage unit D via the intake pipe 401a, and is connected to the cleaning water supply unit E and the water supply pipe 504a. In the apparatus control unit F, an intake pipe 401a includes an intake valve 409 as a valve, a vacuum tank 408 as a decompression unit, an intake pipe 401b, a primary malodor removal filter 407a, a pressure switch 413, an intake pipe 401c, and a solenoid valve 6. The NO port, the COM port of the solenoid valve 6, and the intake pipe 401d are connected to the intake port 402 of the intake pump 400. The exhaust port 405 of the suction pump 400 is connected to the COM port of the solenoid valve 5, and the NO port of the solenoid valve 5 is connected to the secondary malodor removal filter 407 b via the air discharge pipe 414.

  Under such a configuration, in the cleaning process, after the filth is detected by the various sensors G and H, a process of removing malodor caused by the filth in the diaper-shaped casing A is performed. Specifically, in the filth storage tank 300, air is sucked by the operation of the suction pump 400 and is kept at a negative pressure, and the diaper casing A is directed toward the filth inflow pipe 103, the filth storage tank 300, and the suction pump 400. Air flows. This air is the air accompanied by the odor of the filth in the diaper casing A, but the odor is removed by the primary odor removal filter 407a provided between the filth storage tank 300 and the suction pump 400. Since the bad odor is removed by the primary malodor removal filter 407a and the corrosive gas is also removed, corrosion of the suction pump 400 can be prevented.

Further, the air flowing from the exhaust port 405 of the suction pump 400 toward the secondary malodor removal filter 407b is further exhausted by the secondary malodor removal filter 407b and then discharged to the outside. When the air is discharged to the outside, the secondary malodor removal filter 407b is provided to completely prevent the malodor from flowing out to the outside, and the malodor removal effect is longer than when only the primary malodor removal filter 407a is provided. Can be maintained.

  On the other hand, the water pipe 504a includes a filter 507, a water pipe 504b, a pressure pump 600, a water pipe 504c, a T-shaped pipe 412, a nozzle pipe 601, various solenoid valves 1, 2, 3, 4 and various nozzle pipes 602, 603. It is connected to various nozzles 104, 105, 202, and 203 in the diaper casing A through 604 and 605. That is, the cleaning water supplied from the cleaning water supply unit E is pressurized by the pressurizing pump 600 so that the cleaning water can be injected into the diaper casing A from the various nozzles 104, 105, 202, 203. Yes. The filter 507 is for removing foreign matter mixed in the cleaning water so that the foreign matter does not flow into the pressure pump 600.

Under such a configuration, in the cleaning step, the stool pulverization process described above is executed after the step of removing malodors due to the filth in the diaper casing A is executed. Specifically, the suction pump 400 is operated to maintain the suction in the diaper-shaped casing A, the solenoid valve 4 is opened, and the pressurizing pump 600 is operated to inject cleaning water from the stool nozzle 105. Stool crushing process. By the stool pulverization process, the crushed stool is washed away together with the washing water toward the discharge unit 102, and a part of the stool is sucked and stored in the filth storage tank 300 through the filth inflow pipe 103.

However, it is difficult to completely suck and store the filth in the diaper-shaped casing A into the filth storage tank 300 only with the suction force of the suction pump 400. Therefore, in the present embodiment, a vacuum tank 408 for increasing the suction force of the suction pump 400 is disposed between the suction pump 400 and the filth storage tank 300. By forming a vacuum state in the vacuum tank 408, a stronger negative pressure can be generated and the filth in the diaper casing A can be efficiently sucked.

Specifically, the suction valve 409 is closed while the suction pump 400 is operated, the suction of filth from the diaper casing A to the filth storage tank 300 is stopped, and the suction pump 400 is continuously sucked. A vacuum state is formed in the vacuum tank 408. During this time, the stool finely pulverized in the diaper casing A by the stool pulverization process is pushed into the filth storage space s by the water pressure of the washing water. It is not sucked into 103. Therefore, in the filth storage space s, the flow of washing water containing stool is stagnated, and a spiral flow is generated in which the washing water containing stool swirls up and down (hereinafter referred to as an overflow phenomenon). Due to the overflow phenomenon, the stool is further finely pulverized and sufficiently mixed with the washing water, and at the same time, the vicinity of the discharge part 102 where filth is particularly likely to adhere in the diaper casing A is sufficiently washed.

Thereafter, the internal pressure of the vacuum tank 408 is detected by a pressure switch 413 disposed between the suction pump 400 and the vacuum tank 408, and the intake valve 409 is opened at the moment when the internal pressure reaches the maximum vacuum pressure. At this moment, due to the maximum vacuum pressure formed in the vacuum tank 408, the stool that is sufficiently mixed with the washing water due to the overflow phenomenon is sucked and accommodated from the discharge portion 102 to the filth storage tank 300 through the filth inflow pipe 103 at once. Will be.

As described above, the discharge part 102 is inserted into the diaper casing A via the filth storage space s, and the width of the filth storage space s gradually decreases toward the discharge part 102. In other words, the discharge part 102 The width gradually increases toward the side opposite to the portion 102 and forms a cylinder with the discharge portion 102 side as the bottom. With this configuration, when operating the suction pump 400 to suck and store stool in the filth storage tank 300, pressure loss from the suction pump 400 to the diaper casing A can be suppressed as much as possible. , Stool suction efficiency can be improved.

In addition, since moisture accumulates in the vacuum tank 408 due to long-time use, a stopper (not shown) is arranged at the lower part of the vacuum tank 408, and the drainage in the vacuum tank 408 can be drained by removing this stopper. Yes.

As described above, the automatic defecation processing device K is configured to inject air from the various nozzles 104, 105, 202, and 203 to dry the human body after completion of the cleaning process. Specifically, the exhaust port 405 of the suction pump 400 is connected to the COM port of the solenoid valve 5, and the NC port of the solenoid valve 5 includes an air supply pipe 410b, a check valve 411, an air supply pipe 410c, and a T-shaped pipe. 412, the nozzle pipe 601, the various solenoid valves 1, 2, 3, 4 and the various nozzle pipes 602, 603, 604, 605 are connected to the various nozzles 104, 105, 202, 203 in the diaper casing A. .

On the other hand, an external air supply filter 404 is provided on the suction port 402 side of the suction pump 400, and the external air supply filter 404 is connected to the NC port of the solenoid valve 6 via an external air supply pipe 415. The COM port of the solenoid valve 6 is connected to the intake port 402.

With such a configuration, in the drying process, the suction pump 400 is operated with the NC ports of the solenoid valves 2 and 3, the solenoid valves 5 and 6 and the check valve 411 open, so that the air is supplied from the external air supply filter 404. And the air is sent out into the diaper casing A as dry air. Therefore, the air taken in from the external air supply filter 404 is sent out as dry air from the butt nozzle 104 and the anal nozzle 203 so that the human body and the diaper casing A can be dried. The air sent into the diaper casing A is exhausted from the vent hole 112 to the outside of the diaper casing A. In addition, since the check valve 411 is closed during the cleaning process, the cleaning water does not flow back to the suction pump 400.

In the apparatus control unit F, the various solenoid valves 1, 2, 3, and 4 are unitized to form a solenoid valve unit 606 that forms a pipeline with one inflow port and four outflow ports. The solenoid valve unit 606 is configured such that the four outlets can be selectively opened and closed sequentially through a control circuit (not shown). With this configuration, it is possible to simplify the pipeline configuration and reduce the number of parts, and to improve the assemblability.

In addition, the solenoid valves 5 and 6, the external air supply filter 404, the primary malodor removal filter 407 a, the secondary malodor removal filter 407 b, and the pressure switch 413 constitute a single unit to constitute a filter assembly 607. With this configuration, it is possible to simplify pipe formation and reduce the number of parts, improve assembly, and facilitate replacement of various filters 404, 407a, and 407b. Can do.

As shown in FIG. 18, in the automatic defecation processing device K, when the main body is turned on by operating a power switch (not shown), urine is present in the filth channel 101 based on the detection value of the urine detection sensor H. It is determined whether or not to perform (step Sa1).

  If there is no urine as a result of this determination (step Sa1: NO), the automatic defecation processing device K determines whether stool is present in the filth channel 101 based on the detection value of the stool detection sensor G. (Step Sa2). If the result of this determination is that there is no stool (step Sa2: NO), the automatic defecation processing device K returns the processing procedure to step Sa1 again to determine whether or not urine exists. On the other hand, when the stool is present (step Sa2: YES), that is, when only the stool is present in the filth channel 101, the automatic defecation processing device K executes the stool washing process (step Sa4).

  If urine is present in step Sa1 (step Sa1: YES), the automatic defecation processing device K determines whether stool is present in the filth channel 101 (step Sa3). As a result of this determination, if stool is present (step Sa3: YES), that is, if urine and stool are present in the filth channel 101, the automatic defecation processing device K executes a stool washing process for processing stool ( Step Sa4).

On the other hand, if there is no stool (step Sa3: NO), that is, if only urine is present in the filth channel 101, the automatic defecation processing device K executes a urine washing process for processing urine (step Sa5).

  After finishing the stool washing process (step Sa4) or the urine washing process (step Sa5), the automatic defecation processing device K executes a drying process for drying the human body and the diaper casing A (step Sa6).

  FIG. 19 is a flowchart showing the procedure of the stool washing process. In the initial state, the automatic defecation processing device K closes the various solenoid valves 1, 2, 3, 4 and the NC ports of the solenoid valves 5, 6, the intake valve 409, and the check valve 411.

As shown in FIG. 19, the automatic defecation processing device K first opens the intake valve 409 (step Sb1) and starts the intake pump 400 (step Sb2). As a result, the odor of stool inside the diaper-shaped casing A and a part of the stool are sucked into the filth storage tank 300. At the same time, the air containing malodor in the diaper-shaped casing A flows toward the filth inflow pipe 103, the filth storage tank 300, and the suction pump 400, and the secondary odor removal filter 407a before the intake port 402 and the secondary after the exhaust port 405. After the malodor is removed through the malodor removal filter 407b, it is discharged to the outside.

Next, after the solenoid valve 4 is opened (step Sb3), the pressure pump 600 is operated for a predetermined time (step Sb4). As a result, the hot water in the hot water tank 501 is sent to the stool nozzle pipe 605 and sprayed as washing water from the stool nozzle 105, and the stool pulverization process is executed. The stool that has been crushed by the stool pulverization process and pushed in the direction of the filth channel 101 is sufficiently mixed with the washing water by the overflow phenomenon in the filth storage space s (hereinafter referred to as a mixing operation by the overflow phenomenon).

  Next, the automatic defecation processing device K closes the intake valve 409 to start vacuum formation in order to place the vacuum tank 408 in a vacuum state (step Sb5). After waiting until the detected value of the internal pressure based on the pressure switch 413 reaches the maximum vacuum pressure (for example, 600 mmHg) (step Sb6: YES), the automatic defecation processing device K is not illustrated based on the detection signal from the pressure switch 413. The pressure pump 600 is operated via the control device (step Sb7), and the intake valve 409 is opened (step Sb8). At this moment, due to the maximum vacuum pressure formed in the vacuum tank 408, the stool after the mixing operation due to the overflow phenomenon is sucked and stored in the filth storage tank 300 from the discharge unit 102 via the filth inflow pipe 103 (hereinafter, referred to as “stool”). Called vacuum suction operation).

  Then, the automatic defecation processing device K stops the pressurizing pump 600 (step Sb9), and determines again whether there is any remaining stool in the filth channel 101 based on the detection value of the stool detection sensor G ( Step Sb10). If there is a remaining stool as a result of this determination (step Sb10: YES), the automatic defecation processing device K returns the processing procedure to step Sb5 to repeat the mixing operation and the vacuum suction operation due to the overflow phenomenon again. The automatic defecation processing device K repeats the mixing operation and the vacuum suction operation due to the overflow phenomenon until the stool detection sensor G does not detect stool.

As a result, hot water is sent from the hot water tank 501 to the buttocks nozzle pipe 604 and sprayed as washing water from the buttocks nozzle 104 to wash the stool adhering to the vicinity of the patient's buttocks (hereinafter referred to as an ass washing operation). ).

  Next, the automatic defecation processing device K closes the solenoid valve 3 (step Sb14), then opens the solenoid valve 2 (step Sb15), and operates the pressurizing pump 600 for a predetermined time (step Sb16). As a result, hot water is supplied from the hot water tank 501 to the anal nozzle tube 603 and sprayed as washing water from the anal nozzle 203 to wash the stool adhering to the vicinity of the anus of the patient (hereinafter referred to as an anus washing operation). . Furthermore, after closing the solenoid valve 2 (step Sb17), the automatic defecation processing device K repeats the buttocks washing operation and the anus washing operation until the number of washings reaches three (step Sb18: YES). This makes it possible to perform a perfect cleaning of the patient's buttocks and anus.

  Next, when the number of cleaning times reaches 3 (step Sb18: NO), the automatic defecation processing device K opens the solenoid valve 1 (step Sb19) and operates the pressurizing pump 600 for a predetermined time (step Sb20). Thus, hot water is supplied from the hot water tank 501 to the bidet nozzle pipe 602 and sprayed as washing water from the bidet nozzle 202 to wash stool adhering to the vicinity of the patient's genital area (hereinafter referred to as bidet washing operation). .

  Next, the automatic defecation processing device K closes the solenoid valve 1 (step Sb21), stops the suction pump 400 (step Sb22), and then switches the various solenoid valves 1, 2, 3, 4 and solenoid valves 5, 6 to each other. The NC port and check valve 411 are opened (step Sb23), and the suction pump 400 is operated for a predetermined time (step Sb24). Thus, before proceeding to the drying step (step Sa6) described later, the suction pump 400 is operated, and the nozzles of the bidet nozzle pipe 602, the anal nozzle pipe 603, the buttocks nozzle pipe 604, and the stool nozzle pipe 605 are operated. Air taken in from the external air supply filter 404 is blown into the tube to remove moisture (hereinafter referred to as moisture removal operation in the nozzle tube).

Therefore, the expanded front tube 210 and rear tube 211 are tightly clamped between the abdomen and the waist, respectively, and the human body and the diaper casing A can be fixed.

When removing the diaper-shaped casing A from the human body, the front tube 210 and the rear tube 211 are contracted by opening and exhausting valves (not shown) attached to the air outlets 210b and 211b. In addition, it is good also as a structure which installs only any one among the front tube 210 or the rear tube 211, and fixes a human body and the diaper-shaped casing A. FIG.

  Further, as shown in FIG. 33, without attaching the automatic fixing device 205 to the diaper casing A, an elastic material (not shown) is inserted into the rising portion 200, and the tip portion 200a is tilted inward in advance. May be. With this configuration, when the patient wears the diaper-shaped casing A, when the distal end portion 200a is opened in the Z direction, the distal end portion 200a presses the abdomen due to the elastic force of an elastic material (not shown) in the rising portion 200. And the diaper casing A can be fixed.

  Further, as shown in FIGS. 34 and 35, in the diaper casing A, the support plate portion 100 and the rising portion 200 may be separated to fix the human body and the diaper casing A. The diaper-shaped casing A has a support plate part 100, a hinge part 120 provided at the rear end of the support plate part 100, and a rising part 200 installed so as to be rotatable around the hinge part 120. ing.

A screw fastening portion (not shown) is provided inside the hinge portion 120, and the position of the rising portion 200 can be fixed by turning the hinge portion 120 in the right screw direction. The filth channel 101 provided in the support plate unit 100 is separated from the front recess 113 of the rising portion 200, the filth channel 101 is configured to process stool, and the front recess 113 is configured to process urine. Yes. A urine discharge hose 121 for discharging urine is connected to a predetermined portion of the front recess 113, and the urine discharge hose 121 is connected to the filth passage 101 at a predetermined location.

Under such a configuration, when the patient wears the diaper-shaped casing A, the standing part 200 is rotated around the hinge part 120 in a state where the hinge part 120 is loosened and the lumbar part is placed on the support plate part 100. After moving and sticking to the abdomen, the human body and the diaper casing A can be fixed by turning and fixing the hinge part 120 in the right-handed screw direction.

  Further, instead of configuring the stool detection sensor G and the urine detection sensor H to detect stool and urine, respectively, as shown in FIG. 36, a urine detection sensor I that can simultaneously detect stool and urine is adopted. You may do it. FIG. 36 is a schematic view of the urine / feces detection sensor I. The urine / feces detection sensor I includes a pair of sensor units 114 and 114, and the sensor units 114 and 114 are fixedly supported by an insulator 119 at a predetermined interval.

As shown in FIG. 37, each sensor unit 114 includes a temperature sensor 116 having a pair of lead wires 118 and 118, and a conductor 115 that covers the outer edge of the temperature sensor 116. Lead wire 117. As the temperature sensor 116, for example, a thermistor or the like is used, and as the conductor 115, for example, conductive paint, carbon rubber, stainless steel, or the like is used. The conductor 115 is configured to have a predetermined thickness that does not affect the measurement accuracy of the temperature sensor 116, and the lead wires 118 and 118 and the lead wire 117 are configured not to contact each other. ing. That is, the urine / feces detection sensor I has two pairs of lead wires 118, 118, 118, 118 and a pair of lead wires 117, 117 as shown in FIG.

The lead wires 118, 118, 118, 118 are connected to a main body C (not shown) and are set so that a current flows from the main body C. Since the resistance value of the temperature sensor 116 varies as the temperature changes, the main body C is configured to detect the temperature based on a change in the current value accompanying a change in the resistance value of the temperature sensor 116. The lead wires 117 and 117 are connected to a main body C (not shown), respectively, and are configured to allow current to flow from the main body C to only one of them. The urine and urine detection sensor I is configured to detect moisture based on a current value when the conductors 115 and 115 are energized by washing water or urine. The distinction between the washing water and the urine is the same as that of the urine detection sensor H described above, and the description thereof is omitted here.

Under such a configuration, when the temperature sensor 116 detects temperature and the conductors 115 and 115 detect moisture, the urine detection sensor I does not show a detection signal indicating that urine has been detected. It transmits to the main part C. On the other hand, when only the temperature sensor 116 reacts to detect the temperature, the urine / stool detection sensor I transmits a detection signal indicating that stool has been detected to the main body C (not shown).

The urine detection sensor I is installed in the diaper-shaped casing A at the same position as the above-described urine detection sensor H shown in FIG. Therefore, since the urine detection sensor I can reliably distinguish between urine and urine, it is not necessary to use the stool detection sensor G and the urine detection sensor H in combination, and the assemblability can be improved. Electric wiring can be simplified.

  As shown in FIGS. 38 and 39, the raw water tank 500 may be configured so that sterilization can be performed together with the water level sensing of the raw water W. 38 and 39 are schematic views showing the internal structure of the raw water tank 500. FIG. The raw water tank 500 includes an ultraviolet LED 508 disposed at a predetermined location on the upper inner wall surface and a phototransistor 509 disposed at a position facing the ultraviolet LED 508. Further, an upper portion of the raw water tank 500 is provided with a water inlet 500a for pouring the raw water W, and a lower portion of the raw water tank 500 is provided with a water outlet 500b. The water injection port 500a is connected to a water tap through an electromagnetic valve (not shown), and water injection from the water supply is controlled by opening and closing the electromagnetic valve in response to detection by the phototransistor 509. . The water outlet 500b is connected to the solenoid valve 503 shown in FIG.

The raw water tank 500 is configured to transmit ultraviolet rays UV from the ultraviolet LEDs 508 at a predetermined time interval, and to check the water level by receiving the ultraviolet rays UV at the opposing phototransistor 509. As shown in FIG. 38, while the raw water W in the raw water tank 500 is less than a predetermined water level, the phototransistor 509 detects a predetermined voltage value (for example, 4.1 V or more) based on the received ultraviolet light UV. In this state, the electromagnetic valve is opened, and the raw water W is supplied into the raw water tank 500 from the water injection port 500a. When the raw water W in the raw water tank 500 reaches a predetermined water level, as shown in FIG. 39, the ultraviolet LED 508 diffusely reflects the ultraviolet UV in the raw water W, so that the voltage value detected by the phototransistor 509 decreases ( For example, 3.4V or less). When the raw water in the raw water tank 500 reaches a predetermined water level, the supply of the raw water W is stopped based on the change in the voltage value as described above, and the ultraviolet LED 508 is controlled to continuously transmit the ultraviolet UV. The raw water W is sterilized.

  Further, as shown in FIG. 40, when the diaper casing A is used, a mat 10 for a bed that is a set with the diaper casing A may be used. The bed mat 11 is for preventing the fatigue of the waist when the diaper casing A is worn for a long time. When the patient lies on the support plate part 100 and lies down on the support plate part 100, the bed mat 11 It is configured in a substantially rectangular shape so that the upper body side can be supported. The bed mat 11 has substantially the same thickness as the support plate portion 100, and has a concave portion 11a formed on the side surface according to the surface shape of the support plate portion 100, and an end portion on the side where the concave portion 11a is formed. On both sides of the recess 11a, there are provided end portions thereof and a belt 11b fixed thereto. The mat 11 for bed is fixed to the diaper-shaped casing A by fitting the support plate portion 100 into the recess 11a and hanging the belt 11b on the back side of the rising portion 200.

The material of the bed mat 11 is a low repulsive material such as latex in order to minimize the burden on the upper body from the patient's lower back. Several predetermined ventilation holes (not shown) are formed at predetermined locations on the surface of the bed mat 11 so as to improve air permeability and prevent various skin troubles such as eczema and floor rubbing. Further, the outer surface of the diaper-shaped casing A may be covered with a cover made of a fiber material in order to improve the tactile sensation and hygroscopicity of the portion where the diaper-shaped casing A and the human body come into contact.

  In the above-described embodiment, as shown in FIG. 1, room temperature air taken in from the external air supply filter 404 is sprayed from various nozzles 104, 105, 202, 203 as dry air, but is heated. It is good also as composition which injects fresh air. Specifically, a constant temperature heater (not shown) may be brought into close contact with the various nozzle tubes 602, 603, 604, and 605, and air heated by the constant temperature heater may be ejected from the various nozzles 104, 105, 202, and 203. .

  In addition to the above configuration, a flow path for injecting warmed dry air may be separately configured. Specifically, as shown in FIG. 41, the diaper casing A may be configured to include a dry air nozzle tube 201 for blowing warmed dry air. One end of the dry air nozzle pipe 201 is connected to the vent hole 112, and the other end is inserted into the appearance processing hose 111. Further, the appearance processing hose 111 is connected to the exhaust port 405 of the suction pump 400 (see FIG. 1) via a channel with a tube heater (not shown). The air blown from the suction pump 400 is heated through a flow path with a tube heater (not shown), and then passes through the appearance processing hose 111 and the dry air nozzle tube 201 into the diaper casing A from the vent hole 112. It is blown as dry air. The air blown as dry air is discharged to the outside air through the vent hole 122 provided at an arbitrary position of the diaper casing A. With this configuration, since the warmed dry air can be blown into the diaper casing A, the drying effect in the diaper casing A can be improved.
