Abstract

PURPOSE:To suck whole excrement with no remaining left without installation of a larger-sized vacuum pump by closing a connecting hole at the bottom of a storing part by water supplied before and during excretion and sucking abruptly filthy things comprising excrement and water in the storing part after excretion. CONSTITUTION:When a degree of vacuum in a lower part of a tank 5 is raised by driving a vacuum pump 6 to work and a controlling valve 480 is made to be a state of fully opened to atmosphere from a state of opening, an exhaust pressure, which has been caused by the difference of pressure at the pinch valve 41 between the side of a filthy things tank and the side of the cup unit 2 and also at a gap between an exterior and an inner tube pipe of the pinch valve 41, disappears and becomes an atmospheric pressure. Then, the passage of the inner tube is made open by the force which is generated to regain the previous O-shaped section by a restoring force of elasticity. Because of this, the whole space down to the connecting hole 24 at the bottom of the storing part 23, immediately takes the same degree of vacuum as in the tank for filthy things and this difference in the pressure makes the filthy things suck into the tank for filthy things from the storing part 23.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for treating excrement using a cup unit, which can be excreted in a supine position by a person who has difficulty in excreting due to aging or illness.

[0002]

2. Description of the Related Art A conventional excrement disposal apparatus developed for bedridden elderly people is, for example, Japanese Patent Laid-Open No. 61-14.
There is one disclosed in No. 9148. The tray-shaped cup unit receives the excrement, sucks the waste with a waste hose connected to a vacuum pump, and discharges the warm water from above to wash the crotch.

[0003]

However, in the conventional device, when the waste in the tray-shaped cup unit is suctioned and removed by the waste hose connected to the vacuum pump, it is relatively large to remove the waste cleanly. A suction force is required. That is, in the conventional excrement disposal device, not only is the vacuum pump increased in size, but there is no guarantee of safety when inhaled, and there is a problem that the sick person or the like who uses the vacuum pump is anxious. Further, in the future aging era, a large space is not always available in a hospital for the elderly and the like, and it is indispensable to provide a miniaturized excrement disposal device. Furthermore, it should be noted that the device is a device for removing filth so that the filth remains on the device itself and the environmental conditions for medical treatment deteriorate.

The present invention has been made in view of the above,
It is an object of the present invention to provide an excrement disposal method and device capable of obtaining a filth suction force capable of sucking all the filth causing an offensive odor without increasing the size of the vacuum pump.

[0005]

In order to achieve the above object, the method of treating excrement according to the present invention comprises: a cup unit, which fits closely to the crotch area, a water supply port, and a storage section formed at the bottom. A waste suction port that communicates with the bottom communication port of the storage unit and is raised to a predetermined height level is provided, and water is supplied to the storage unit from the water supply port before or during use, and The bottom communication port is closed, and after use, the filth in the storage part composed of the water and excrement is rapidly sucked from the filth suction port to the filth tank (claim 1).

It is preferable that the water supply port is a nozzle for ejecting washing water toward the crotch portion (claim 2), and the washing water is warm water (claim 3).

Further, the excrement disposal apparatus of the present invention comprises: a cup unit which is tightly applied to the crotch part; a nozzle for ejecting washing water toward the crotch part;
Provided with a waste suction port which is communicated with the bottom communication port of the storage section and raised to a predetermined height level, the nozzle is connected to a wash water tank through an opening / closing valve, and the waste suction port is A waste tank that is sucked by a suction pump is connected through a waste hose and a pinch valve, and the opening / closing valve is opened before use to supply cleaning water from the nozzle to the storage section, and the cleaning water is used to connect the bottom section. The mouth is closed, and after use, the pinch valve is opened to provide a control means for sucking filth in the storage portion composed of washing water and excrement from the filth suction port to the filth tank (claim 4). .

The washing water tank may be provided with a heater for heating (claim 5), and the washing water tank serves as a pressure source for supplying washing water from the washing water tank to the nozzle. The exhaust pressure of the suction pump can be applied to the device (claim 6).

[0009]

In the method of claim 1 and the apparatus of claim 4, first, before the cup unit is used by a sick person or the like,
Water is stored in the storage portion of the cup unit, and the bottom communication port of the storage portion is closed with water. Before and after this, the sick person applies the cup unit to the crotch area in close contact. After the use of the cup unit, the filth in the storage portion composed of the water and the excrement is rapidly sucked into the filth tank from the filth suction port.
At this time, since the bottom communication port of the storage part is blocked with water, a large negative pressure is temporarily applied, and all the waste in the storage part is sucked cleanly from the waste suction port at once.

Further, since the offensive odor from the waste hose is blocked in advance by the water accumulated in the storage section and the excrement is dropped into the stored water to cut off the offensive odor, it is also effective in hygiene.

According to a second aspect of the present invention, as a means for supplying water into the storage part, instead of providing a dedicated water supply port, a structure which doubles as a nozzle for ejecting washing water toward the crotch part is adopted. This can reduce the number of nozzles.

In view of the fact that the sick person applies the cup unit to the crotch portion closely, it is possible to warm the cup unit in advance by using warm water for the washing water. I am trying. For this purpose, the washing water tank may be provided with a heater for heating as described in claim 5.

According to a sixth aspect of the present invention, the exhaust pressure of the suction pump is used as the supply pressure source of the washing water to form a kind of water supply pump, so that the apparatus can be made compact, and the apparatus can be moved and moved. Simplification such as maintenance can be achieved.

The control device 90 shown in FIG. 12 opens the on-off valve 71 before use to supply the wash water from the nozzle 27 to the storage part 23 to close the bottom communication port 24 with the wash water, and after use. A control means for opening the pinch valve 41 to suck the filth in the storage portion 23, which is composed of wash water and excrement, from the filth suction port 24 to the filth tank 5.

FIGS. 21 and 22 show a portion of a residual water suction pipe 30 provided in the middle of the waste hose 3 for sucking the residual water in the waste hose 3. Residual water suction pipe 30
Has a joint 32 of the residual water suction tube 31 at an intermediate portion and joints 33 and 34 at both ends.
In addition, on the lower surface in the middle of the residual water suction pipe 30, an installation stand 35
Is provided, and the portion of the joint 32 of the residual water suction tube 31 is configured to open to the bottom surface or lower portion of the residual water suction tube 30.

(4) Operation Next, the operation of the above configuration will be described step by step with reference to FIG. (1) Closure of Bottom Communication Port 24 by Stored Water First, cleaning water is supplied into the storage unit 23 of the cup unit 2 to store the inside of the storage unit 23 at the bottom communication port 24 at the lower rear end thereof.
To the level where it is blocked. This is done as follows.

By pushing the "start operation" button of the remote controller 10, the pinch valves 41 and 45 are "closed" (the control valves 480 and 490 are "open"), the first opening / closing valve 63 and the second opening / closing valve 71 are "closed". The vacuum pump 6 is driven in the "open" state. Since the exhaust pressure of the vacuum pump 6 is sent to the wash water tank 7,
The pressure in the wash water tank 7 is increased, and the wash water (warm water) in the wash water tank 7 is connected to the wash hose 8 by the pressure (in this embodiment, the wash water jet nozzle for women is used). 27). Therefore, the cleaning water jet nozzle 27 functions here as a water supply port for the reservoir 23.

When a predetermined amount of washing water is stored in the storage portion 23 of the cup unit 2 and the bottom communication port 24 is closed by this storage water, the second opening / closing valve 71 is closed. Therefore,
By closing the second opening / closing valve 71, the supply of washing water is stopped, and the inside of the washing water tank 7 is pressurized to a predetermined pressure which is slightly higher than before.

(2) Cleaning After excreting, the second opening / closing valve 71 is opened again by pressing the "cleaning start" button on the remote controller 10, and the cleaning water (warm water) in the cleaning water tank 7 is heated by the above predetermined high pressure. ) Is sent to the washing hose 8 and is jetted vigorously from the washing water jet nozzle 27 for women. The sprayed cleaning water is shown in FIG.
As described above, it becomes hot water that spreads flat and fan-shaped in the vertical plane from the upper part of the urethral opening to the lower part of the urethral opening. be able to. Therefore, compared to the type in which the wash water is allowed to flow down from above, the contaminated wash water after washing does not reach the urethral meatus, etc., and therefore Escherichia coli etc. enter the urethral meatus, etc. It is possible to prevent the inconvenience of the onset of the above.

(3) Suction with the dirt hose This is because after the above-mentioned cleaning, the "suction start" button of the remote controller 10 is pressed to suck the dirt with the dirt hose 3 and the residual water suction tube 31 that follows. The residual water is sucked. First, as described above, the control valve 48
Both 0 and 490 are in the “open” state, the exhaust pressure of the vacuum pump 6 is drawn into the pinch valves 41 and 45, and both the pinch valves 41 and 45 are in the “closed” state. When the vacuum pump 6 is driven in this state, the degree of vacuum of the tank lower portion 51 is increased via the connecting pipe 61 and the connecting end 57, and through the gap between the tank upper portion 54 and the suction joint pipe 55 and the inner lid 56 in the waste tank 5. .

Then, after the vacuum state is raised, the dirt is sucked. That is, of the control valves 480 and 490, the control valve 480 is changed from the "open" state to the "atmosphere open" state. As a result, the exhaust pressure of the vacuum pump 6 that has been applied to the gap 415 between the outer cylinder and the inner cylinder of the pinch valve 41 up to that time disappears due to the pressure difference between the waste tank 5 side of the pinch valve 41 and the cup unit 2 side. Then, the pressure becomes atmospheric pressure, and the passage of the inner cylinder 412 is opened by the force of the inner cylinder 412 to return to the original O-shaped cross section by the elastic return force. For this reason, the inside of the space up to the bottom communication port 24 of the storage portion 23, which is closed by the filth consisting of wash water and excrement, suddenly becomes the same degree of vacuum as the filth tank 5, and due to this pressure difference, a temporarily large negative pressure is exerted. However, the waste is sucked into the waste tank 5 through the waste hose 3 from the storage portion 23 at once all at once.

When the waste is sucked into the waste tank 5, it is sucked from the suction joint pipe 55 to the tank lower portion 51. At this time, the tank lower part 51 is partitioned by the tank upper part 54 and the inner lid 56, so that the filth does not enter the tank upper part 54, the dirty water does not enter the vacuum pump 6, and the shortening of the life can be prevented. It is preferable that a deodorant or other chemical is placed in the tank upper portion 54 to remove harmful substances from the vacuum pump 6.

Next, the procedure for removing the residual water remaining in the waste hose 3 will be described. First, the control valves 480, 4
Both 90 are in the "open" state, the exhaust pressure of the vacuum pump 6 is drawn into the pinch valves 41, 45, and both the pinch valves 41, 45 are in the "closed" state. In this state, the vacuum pump 6 is driven, and the degree of vacuum of the tank lower portion 51 is increased via the connecting pipe 61 and the connecting end 57 and the gap between the tank upper portion 54 and the suction joint pipe 55 and the inner lid 56 in the waste tank 5. .

Next, after the vacuum state in the waste tank 5 is raised, the control valve 4 of the control valves 480 and 490 is controlled.
90 switches from the "open" state to the "open to the atmosphere" state.
As a result, due to the pressure difference between the waste tank 5 side of the pinch valve 45 and the residual water suction pipe 30 side, and the exhaust pressure of the vacuum pump 6 that has been given to the gap 455 of the pinch valve 45 up to that point disappears to atmospheric pressure. The inner cylinder 452 elastically returns to the original O-shaped cross section, and the passage of the inner cylinder 452 opens. At this time, the joint 2 of the residual water suction tube 31 is opened to the bottom surface or the lower part of the residual water suction tube 30 and is configured to block even the lowest level residual water in the tube by this. The space up to the opening of the residual water suction pipe 30, which is blocked by the residual water, suddenly becomes the same degree of vacuum as the waste tank 5, and due to this pressure difference, the residual water is completely sucked and removed with a large negative pressure. .

In the above embodiment, the wash water jet nozzle 27 or 28 is used as the water supply port for filling the storage portion 23 before use, but the wash water jet nozzle 27 or 2 is thus used.
It is also possible to provide a dedicated water supply port to the storage section 23 without using the double function. Further, in this case, the cleaning water supplied to the cleaning water jet nozzle has a different component from the cleaning liquid for cleaning the body, and for example, cleaning water of a component which is unlikely to be contaminated in the storage part of the cup unit or the waste hose or a component having high cleaning ability. Needless to say,

[0043]

As described above, according to the present invention,
The following excellent effects can be obtained. 1) In the method of claim 1 and the device of claim 4, since the bottom communication port of the storage portion of the cup unit is previously closed with water, when suctioning from the waste suction port connected to this, A large negative pressure, which is much larger than when it is not blocked, is temporarily created, and all the waste in the storage section is sucked at once from the waste suction port. As a result, a desired suction operation can be performed using a vacuum pump smaller than the conventional one. Further, the offensive odor from the waste hose is blocked in advance by the water accumulated in the storage part, and the excrement is dropped into the stored water to cut off the offensive odor.
Also effective in hygiene. 2) According to claim 2, since the water supply port into the storage portion is also used as the nozzle for ejecting the washing water toward the crotch portion,
The number of nozzles can be reduced. 3) According to claim 3 or 5, the cup unit can be warmed in advance before the sick person applies the cup unit to the crotch portion. 4) According to the sixth aspect, the exhaust pressure of the suction pump is used as the supply pressure source of the wash water to form a kind of water supply pump, so that the apparatus can be made compact.
