The waste collection pipes 5, 10 have such a structure that not only liquids such as excrement but also air can flow.
It is made of a bent tube having rigidity so that the pipe diameter does not become small even when the waste is sucked into the waste tank 13 by the pressure difference of air.

The excrement and the like sucked into the waste tank 13 by the air pump 15 store the excrement and the washing water after excretion in the lower part of the waste tank 13.
The air is sucked into the air pump 15 via the air pump 8. Waste tank 1
Reference numeral 3 denotes an inlet 19 connected to the waste collection receptacle 2 of the attachment 1 via the waste collection pipe 10, and an outlet 20 connected to a suction port of the air pump 15.

The inside of the tank 13 is maintained at a negative pressure by sucking air by an air pump 15, and the waste collection pipe 2, the waste collection pipes 5 and 10, the waste tank 13, the air pump 1
It has a structure in which air always flows toward 5.

A gas detector 16 is attached to an air pipe 18 connecting the waste collection receptacle 2 and the air pump 15. As the gas detector 16, for example, an air pressure detector or the like is used, and when the patient wearing the attachment 1 excretes or the like, the excrement accumulates in the filth collection receptacle, and the filth collection pipe 5 Is sensed as a change in the pressure of the airflow passing through the waste collection pipe 10, the waste tank 13, and the air pipe 18. The gas detector 16 detects this change (excretion) and transmits it to a control device (not shown). The control device activates the air pump 15 to suck the excrement and the like from the waste collection receiver 2 and collect it in the waste tank 13. At the same time, the operation of the air pump 15 is switched to an operation mode in which cleaning water or dry air is supplied from the suction cleaning unit 12 to the nozzles 3 and 4 of the attachment 1.

In addition to the pressure detection, the gas detector 16 may be a detector using a detection sensor, a temperature sensor, and a flow sensor for detecting ammonia and odor components in the excrement on the suction cleaning unit 12 side of the processing apparatus. The signal transmission to the control device after detecting that the air pressure has occurred is the same as that of the air pressure detector.

The discharge port of the air pump 15 is
It is connected to the nozzles 3 and 4 via the air filter 22, the air pipe 28, the air heater 23, the air switching electromagnetic valve 24, the germicidal lamp 25, the cleaning pipe 11, the pipe connector 8, and the branch pipe 6 to supply air. .

On the other hand, some air is supplied to the 5-port solenoid valve 34.

A part of the air used for driving the plunger pump 17 is returned to the air pipe 28 again through the air pipe 53 and the vacuum switching solenoid valve 27, or the activated carbon filter 54
It is released outside the device after being deodorized.

The cleaning pipes 9 and 11 pressurize the water in the cleaning water tank 42 by the plunger pump 17 and apply pressure to the nozzles 3 and 4.
The genital area and the anus after excretion (referred to as genital area, etc.) can be washed with water by supplying the genital water and squirting the washing water.

On the other hand, dry air is supplied from the nozzles 3 and 4 via the air switching electromagnetic valve 24 to dry the pubic area and the like after washing, and to prevent a part of the body to which the attachment 1 is attached from being moistened. I have to.

Nozzle 3 mounted on waste collection receptacle 2
Is used for cleaning the anus and supplying dry air, and the nozzle 4 attached to the cover 52 is used for cleaning the pubic region of a woman and supplying dry air into the attachment 1.

Thus, the air pump 15 not only operates the plunger pump 17 but also operates the waste tank 1
The air sucked in from the 3 side is pressurized, and the nozzle 3 of the attachment 1 is
4 to be discharged into the attachment 1, and the cover 52 of the attachment 1, the waste collection receptacle 2, and the body 7 of the patient.
The air circulating through the wastewater collecting pipes 5 and 10 is again sucked into the waste tank 13 through the wastewater collecting pipes 5 and 10, and is again sucked into the air pump 15 through the air pipe 18.

This recirculated air is deodorized by an activated carbon filter 30 for deodorization before being sucked into the suction port of the air pump 15, and is discharged from the discharge port of the air pump 15 to the air pipe 21.
Is discharged as indicated by an arrow A, and the air filter 22 removes moisture contained in the air.

Before the air is supplied to the nozzles 3 and 4, the air is heated and dried by the air heater 23, and sterilized by the germicidal lamp 25. 9 and are supplied to the nozzles 3 and 4.

On the other hand, the supply of the washing water to the nozzles 3 and 4 is as follows.
The water in the washing water tank 42 is suctioned and pressurized by the plunger pump 17 through the water pipe 32 and the washing water switching solenoid valve 31 as shown by the arrow W, and again the washing water switching solenoid valve 31 (3-port solenoid valve) and the water pipe 33. The air is supplied to the nozzles 3 and 4 via an air switching electromagnetic valve 24 (3-port electromagnetic valve), a germicidal lamp 25, and washing pipes 11 and 9.

In the cleaning pipes 11 and 9, only ventilation air is independently supplied through a single pipe, or a mixture of cleaning water and ventilation air is supplied.

The plunger pump 17 includes an air pump 15
The pressurized air is alternately supplied to the left and right sides of the drive-side piston 26 by the 5-port solenoid valve 34 so that the water chamber-side piston 29, which is directly connected to the air, sucks and compresses water. It was done.

At this time, the flow of the washing water is switched by the washing water switching solenoid valve 31 to the water pipes 32 and 33, and flows from the water pipe 32 to the plunger pump 17 and from the plunger pump 17 to the water pipe 33. Of water is alternately performed, so that cleaning water is intermittently supplied from the nozzles 3 and 4 connected to the cleaning pipes 11 and 9 connected thereto, and the anus and the genital area are supplied intermittently. Can be washed with water. In this case, the air switching electromagnetic valve 24
Is switched, ventilation air A is shut off, and water W is supplied to the nozzles 3 and 4.

As a result, the washing water W sent out is mixed with the air remaining in the washing water pipes 11 and 9 and supplied to the nozzles 3 and 4, where it is jetted out to wash the anus and the genital area. . By shutting off the ventilation air during the supply of the cleaning water W, the internal pressure of the attachment 1 decreases. Therefore, it is difficult for the odor to escape to the outside of the attachment 1, and odor leakage is suppressed.

When the cleaning water W is supplied by changing the mechanism of the air switching electromagnetic valve 24, it may be supplied together with the ventilation air. In this case, since external pressure always acts inside the attachment 1 during the cleaning, the odor hardly escapes to the outside of the attachment 1, thereby suppressing odor leakage.

Further, by changing the structure of the outlet of the nozzle 4, the shape of the washing water spouting toward the genital area after excretion can be changed to an elliptical cone shape along the crotch or a substantially vertical straight washing water. By irradiating the washing water having such a shape along the crotch, the pubic region and the like can be effectively washed with a small amount of water.

As described above, the nozzles 3 and 4 are used for cleaning the pubic region and the like, the drying nozzle for drying the pubic region and the like after the cleaning, and for preventing the skin of the portion where the attachment 1 is attached from becoming moist, rash, and humiliating. It also serves as a circulating air supply nozzle that dries the skin.

The structure of supplying the washing water and the dry air to the nozzle is not limited to the above description, and the structure of the nozzle through a flow rate adjusting valve or a water pressure adjusting valve (both not shown) connected to the plunger pump 17. Cleaning water, ventilation air, and drying air may be selected or mixed and supplied to 3 and 4.

The waste tank 13 has a tank 36, a waste liquid pipe 37, and a lid 38 which can be easily attached and detached. A liquid level window 39 on the side wall of the tank allows the amount of excrement and the like in the tank to be seen. It has. The waste liquid pipe 37 is a tank 36
It is a bendable pipe that discharges excrement and the like inside, and usually has a cap 40 at the tip.

A waste collection pipe 10 and an air pipe 18 are attached to a lid 38 of the tank 36.
The excrement sucked into the waste tank 13 flows down into the tank 13, and only the air in the tank flows out to the air pipe 18 through the outlet 20.

Reference numeral 41 denotes a lever for attaching the lid 38 to the tank 13 in an airtight manner. Thereby, the person using the excrement disposal apparatus can easily remove only the tank portion from the suction cleaning unit 12 by removing the lid 38 when the excrement or the like in the tank is almost full or when cleaning the waste tank 13. Can be removed, and no special equipment or sensors are attached to the tank part. Therefore, at a sewage treatment plant or toilet, wastes are discarded from the waste liquid pipe 37 and the lid 38 is removed from the opening as appropriate. The tank can be washed while pouring water.

A lid 38 is attached to the tank in which the excrement and the like are discarded and the tank 13 after the excrement is washed, and by operating the lever 41, the waste collection pipe 10 and the air pipe 18 are again attached to the excrement. The processing device is ready for use.

The washing water tank 14 has a lid 43 having a water supply valve (not shown). When the water inside the washing water tank 42 is reduced and an air layer is formed, the air flows into the tank 14 and the inside of the tank is removed. And water is supplied from the water supply tank 14 so that the washing water tank 42 is always filled with water.

The washing water tank 42 has an electric heater 44 and an air heater 23. The electric heater 44 heats water in the water tank to, for example, about 50.degree.
7, when the washing water is blown out from the nozzles 3 and 4 through the water pipe 33, the washing pipe 11, and the like, the washing water is supplied at a temperature at which the user of the attachment 1 does not feel uncomfortable with the cold temperature. In addition, a temperature thermo 45 and a water level gauge 46 are attached to the water tank 42 to maintain and manage the water temperature, prevent overheating, and prevent drought and empty heating in the water tank.

The air heater 23 is, for example, a spiral hollow tube inserted into a water tank, and is heated while the air flowing through the air tube 28 flows through the spiral tube and flows out of the water tank. When the air is discharged from the nozzles 3 and 4 through the cleaning pipes 11 and 9, the air becomes dry air maintained at an appropriate temperature.

FIG. 2 is a cross-sectional view showing an embodiment of the structure of a waste collection pipe on the attachment side, and a pipe connector for connecting the cleaning pipe with the waste collection pipe and the cleaning pipe on the suction cleaning unit side. It is a longitudinal cross-sectional view which shows one Embodiment of the holding mechanism of the pipe connector similarly.

The pipe connector 8 includes a receiving connector 49 to which the tips of the waste collection pipe 5 and the cleaning pipe 9 on the attachment 1 side are air-tightly fixed, and a tip of the waste collection pipe 10 and the cleaning pipe 11 on the suction cleaning unit 12 side. Is provided with an insertion-side connector 50 and a holding mechanism 51 which are hermetically secured.

The receiving connector 49 includes a waste collection pipe 5
A connection port 57 of the waste collection pipe 10 having an O-ring 47 in an opening slightly larger than the inner diameter of the cleaning water pipe 11 and a connection port of a cleaning water pipe 11 having an O-ring 48 in an opening slightly larger than the inner diameter of the cleaning water pipe 9. 58 are provided.

The insertion-side connector 50 has an opening having the same inner diameter as the inner diameter of the waste collection pipe 10 and has the receiving-side connector 49.
The insertion port 67 has an insertion end 67 which is fitted into the connection port 57 and is hermetically joined by contacting the O-ring 47 and also has an opening having the same inner diameter as the inner diameter of the washing water pipe 11.
And an insertion end 68 that is fitted into the O-ring 48 and is airtightly joined by contacting the O-ring 48.

When the insertion-side connector 50 is fitted to the receiving-side connector 49, the connectors may be held by frictional force.
It is preferable to obtain a holding force stronger than the friction force.

The pipe connector 8 has a cap (not shown), and when the connector 50 on the insertion side is removed, the washing pipe 9 and the waste collection pipe 5 of the receiving connector are removed.
Is sealed with a cap. Thereby, even when the connector 50 on the insertion side is removed, it is possible to prevent the odor and excrement from the waste collection receptacle 2 from leaking through the openings of the pipes 5 and 9.

In this way, if the attachment 1 and the apparatus suction / cleaning unit 12 are connected by the connector 8 which can be easily separated, the patient can remove the attachment 1 for a short time without any adverse effect. While being attached, it can be separated from the excrement treatment apparatus suction / cleaning unit 12 and moved out or moved in a wheelchair.

In particular, when the detector for detecting excretion is provided only on the suction cleaning unit side of the excrement disposal apparatus as in the present invention, the attachment 1 can be removed from the suction cleaning unit 12 side, or the suction cleaning unit can be removed. Connection to 12 has no effect on the operation of the processing device. In addition, the absence of precision equipment or electrical equipment such as a detector on the attachment 1 side means that the attachment 1 can be removed and easily cleaned, and the device used by attaching to the patient's body is always used. It can be kept hygienic and prevent any adverse effects on the skin.

The tip hook 63 of the lever 62 of the holding mechanism 51 is, for example, a lock that cannot be disengaged from the projection 64 on the receiving side unless the lever 62 is operated. It is preferable to use a loose or an obtuse angle so that it can be detached even when it is in a state of being left as it is.

The connecting connector 49 on the receiving side and the connector 50 on the inserting side connected in this manner are connected to the lever 62 by operating the lever 62 when the patient is evacuated in an emergency such as a natural disaster or fire. Not only can it be easily separated from the suction / cleaning unit 12 side, but also if a person unfamiliar with the operation of the lever 62 of the holding mechanism 51 cannot remove the holding mechanism, they can be detached from each other by forcibly pulling the connectors.
Separating the attachment 1 from the suction washing unit 12 while the patient is wearing the attachment 1,
The patient can be evacuated promptly while the attachment 1 is being worn.

The above holding mechanism has been described as an embodiment, but is not limited to this. For example, the pipes are normally airtightly connected to each other, but the pipe connector 8 may be constituted by an emergency separating device which is disconnected or broken if a stronger force is applied than in a normal use state in an emergency. .

As described above, the operation of the excrement disposal apparatus of the present invention is performed by attaching the attachment 1 to a person or the like who has difficulty excretion using the oscillary cover or a similar tool. Collection pipe 5
A cleaning pipe 11 on the suction cleaning unit side and a waste collection pipe 10 are detachably connected to each other through a pipe connector 8, so that a small amount of dry air is always supplied to the attachment 1 from the air pump 15 and circulated.

Thus, the air having the odor at the time of excretion does not directly discharge to the outside, and when excretion occurs, the excrement and the like are received by the waste collection receptacle 2. When excretion occurs, the entrance of the waste collection pipe 5 is blocked, the flow and pressure of the air in the waste collection pipe 5 change, or the odor and humidity of the circulating air change. In this case, a change on the attachment 1 side is detected by a sensor attached to the suction / cleaning unit side, and a signal is sent to the control device.

The control device increases the suction capacity by increasing the capacity of the pump by inverter control of the air pump 15 and the like, and reduces the pressure in the waste storage tank 13 so that the waste and the like in the waste collection receiver 2 are transferred to the waste tank 13. After suction, only air from the tank passes through the activated carbon filter 30 and the like, and returns to the pump 15 again.

The operation of the mechanism for cleaning the pubic region and the like after excretion by the nozzles 3 and 4 is such that the washing water is sprayed a plurality of times and the drying cycle with warm air is repeated. For example, there is provided a detecting means 16 for detecting the dirt excreted in the dirt collection receptacle 2, and when the detecting means 16 detects dirt, the ventilation air is shut off for a predetermined time (for example, 3 to 7 seconds). The cleaning water is supplied to the attachment 1, and then only the ventilation air is supplied to the attachment 1 for a predetermined time (for example, 30 seconds), and the ventilation air is shut off for a predetermined time (for example, 3 to 7 seconds). The washing water is supplied to the attachment 1, and the above operation is repeated at least once. When supplying the cleaning water, as described above, the cleaning water may be supplied together with the ventilation air.

The end time of this cycle can be adjusted in advance by a timer or the like depending on whether excretion is for small amounts or for defecation. By the time-up of the washing and drying cycle, the operation of the solenoid valve 34 is stopped, the operation of the solenoid valve 31 is switched to the solenoid valve 24, and the operation of the air pump is returned to the normal operation state.

The air sent from the air pump 15 by switching to the solenoid valve 24 is supplied to the air pipe 28 and the air heater 2.
3. Return to the normal operation of recirculating air returning to the air pump 15 via the cleaning pipe 11, the nozzles 3, 4, the waste collection pipes 5, 10, and the waste tank 13.

In this embodiment, the simplicity and compactness are emphasized, and a plunger pump using air as a power source has been described as a pump for supplying washing water and dry air and sucking excretions. May be another type of pump powered by electricity, a separate pump for supplying dry air or washing water, or a vacuum pump for suction may be used independently.

The above description shows an embodiment of a basic operation system for achieving the object of the present invention, and the method and principle are not limited to this embodiment.

[0075]

According to the present invention, ventilation air is circulated to the attachment through the cleaning pipe connected to the jet nozzle, so that odor leakage is suppressed. In addition, since the pipe for ventilation air circulation and the pipe for supplying cleaning water are also used, the piping configuration of the pipe is simplified. In the present invention,
Since the operation of supplying only the ventilation air and the operation of supplying the cleaning water together with the ventilation air are repeated, the excrement is efficiently discharged from the waste collection receptacle. In the present invention,
For example, when the patient is evacuated in an emergency such as a natural disaster or fire, the single pipe connector can be separated and the patient can be evacuated with the attachment attached. Further, according to the present invention, when the attachment and the suction cleaning unit side are separated by a pipe connector, the detection means does not need to be left on the suction cleaning unit side and need to be electrically connected to the attachment. Can provide an excrement disposal device that is less likely to hinder the evacuation of a patient.
