Description: TECHNICAL FIELD The present invention relates to an improvement of a bed with a toilet used for a physically handicapped patient, a bedridden elderly person, and the like.

[Prior Art] Conventionally, as this type of bed, as disclosed in Japanese Patent Application Laid-Open No. 58-81038, a through-hole is opened and closed by an air mat, and it is disclosed in Japanese Utility Model Laid-Open No. 62-194336. To flush the toilet bowl after defecation, as in US Pat. No. 3,943
It has been known to move an auxiliary mattress or a toilet with a driving device as disclosed in US Pat. No. 3,583 and US Pat. No. 4,754,508.

[Problems to be Solved by the Invention] Meanwhile, the above-mentioned conventional ones have the following problems (problems).

That is, in the bed disclosed in JP-A-58-81038,
If the air mat is softened to provide cushioning to the buttocks, the through holes cannot be sealed with this mat, and there is a problem that an odor drifts after defecation.

Further, the beds disclosed in U.S. Pat. No. 3,943,583 and U.S. Pat. No. 4,754,508 require complicated and large-scale driving devices for moving auxiliary mattresses and toilet bowls, which is a drawback of high manufacturing cost. there were.

Further, in the bed disclosed in Japanese Utility Model Laid-Open No. 62-194336, although the excrement is washed away with water, it is hygienic, but when the toilet is used, if the toilet is dry, the excrement tends to stick. was there. For this reason, it was difficult to wash off the excrement adhering to the toilet bowl, and a large amount of water had to be used to wash it off.

An object of the present invention is to provide a bed with a toilet bowl that solves the above-mentioned problems (problems) of the conventional one.

[Means for Solving the Problem] The present invention provides a bed with a toilet provided with a mat, a toilet attached to a through hole formed in the mat, and a discharge pipe for discharging excrement in the toilet. The present invention relates to a toilet bed in which the toilet bowl is provided with a pad that contracts to open the toilet opening of the toilet bowl and expands to support the buttocks, and the exhaust tube is provided with a valve that opens and closes the conduit.

In this case, it is desirable that the pad be a bed with a toilet bowl composed of multiple rubber tubes.

Further, the pad is composed of a plurality of sets of rubber tubes, and one set of rubber tubes and the other set of rubber tubes are alternately expanded in a state where the pipe line of the discharge pipe is closed by a valve,
It is desirable to use a bed with a toilet bowl that is made to shrink.

Further, the valve can be a bed with a toilet formed by a rubber ball that is expanded to close the conduit of the discharge pipe and contracted to open the conduit.

Moreover, in a bed with a toilet provided with a mat, a toilet attached to a through-hole formed in the mat, and a discharge pipe for discharging excrement in the toilet, the discharge pipe is provided with this conduit before defecation. There is a valve that closes and opens after defecation.
It is preferable that the toilet bowl be a bed with a toilet provided with an inlet for generating bubbles in the toilet before defecation and a pad that is contracted to open the toilet opening of the toilet during defecation.

[Operation] In a bed with a toilet having a through hole formed in a mat, the present invention is provided with a pad for supporting the buttocks by contracting the toilet bowl to open the toilet bowl of the toilet bowl and expanding the toilet bowl. When performing the operation, if the central rubber tube of the plurality of rubber tubes constituting the pad is contracted to both sides and opened, the toilet bowl of the toilet located below is opened.

When defecation or urination is performed here, the excrement is discharged from the toilet bowl to the toilet bowl through the discharge tube.

After defecation and urination, the rubber tubes of the pad expand to function as an auxiliary mat that covers the toilet bowl and supports the buttocks.

In this case, the pad needs to be flexible even when inflated in order to give the buttocks a cushioning property. Therefore, there is a gap between the rubber tubes and the toilet bowl. Since the pipe line is sealed with a valve, the odor is not immediately released into the room from the faucet through the through-hole without discarding the excrement.

Moreover, a kind of massage effect can be obtained by alternately expanding and contracting a plurality of rubber tubes supporting the buttocks by the operation of the air supply / exhaust device, and at the time of this expansion / contraction, the conduit of the discharge pipe is valved. Since it is sealed with, the odor of excrement is not released indoors.

In addition, before defecation, the valve is closed to create bubbles in the toilet bowl, and then defecation is performed in this, and by opening the valve, excrement can be dropped rapidly into the toilet bowl and removed. Even if it is stool (soft stool or hard stool), it does not adhere to the toilet bowl and the toilet bowl does not get dirty. In addition, the odor of feces in the toilet bowl is contained by the bubbles.

After defecation, after cleaning the inside of the toilet bowl, close the valve to fill the inside of the toilet bowl with water, and contract all the rubber tubes of the pad to lower the buttocks and soak in the water in the toilet bowl, and bubble this water. You can take a bath by doing this.

As shown in FIG. 10B, it is a cover which is used to hide the local area 9b of the sick person 9, and is normally used as a cover for covering the pad 7 as shown in FIG. 10C.

The rubber tubes 7a to 7e and the valve 14
The air used for expansion and contraction can be replaced with another fluid such as oil.

Next, this operation will be described. First, when using as an ordinary bed, the air compressor of the air supply / exhaust device 10
10a is driven to expand the rubber tubes 7a to 7e as shown in FIGS. 3 and 4.

In this case, the rubber tubes 7a and 7b in the center are abutted against each other to maintain a flat state. In this state, the patient 9 may lie flat on the mat 4 and lie down.

At this time, the buttocks 9a are supported by the rubber tubes 7a, 7b and the rubber tubes 7c, 7d, 7e.

Here, when the depressed person 9 defecates and urinates (may be abbreviated as excretion), first the backrest 4c of the mat 4 is raised as shown in FIG. Sit down 9.

After this, the vacuum pump 10b for air suction of the air supply / exhaust device 10
By forcibly sucking and contracting the air in the rubber tubes 7a and 7b by driving the rubber tube 7c, the toilet opening 8 is opened in the center and expanded as shown in FIGS. 5 and 6. 7e
Functions as a toilet seat.

Then, as shown in FIG.
Closed, and a certain amount of warm water is supplied from the warm water supply port 15 to the toilet bowl 6 by a pump or the like to store it, and liquid detergent or a highly concentrated water solution of the detergent is added from the inlet port 16 by the metering pump and the toilet bowl 6 Air is supplied from the air outlet 17 at the bottom so that the bubbles 30 stand in the toilet bowl 6.

Especially when using the foam of detergent, it is more effective to use warm water. And defecate in this.

Usually, it is enough to store water in the toilet bowl 6, but by using the foaming of the detergent, it is possible to treat the water with a smaller amount of water, and instead of foaming in the toilet bowl with this foam, another container is prepared in advance. When a mixture of detergent and water is bubbled in an air pump (not shown) and the foam is supplied into the toilet bowl 6 from the inlet 16, the toilet bowl 6 is filled with a large amount of foam, and the foam causes the toilet bowl 6 to fill. The odor of feces 31 inside is more reliably contained, so the odor does not drift indoors.

The detergent may be either an oil-based detergent or a synthetic detergent. However, since the oil-based detergent loses bubbles earlier than the synthetic detergent, there is no fear that the toilet tank 13 will be filled with bubbles. preferable.

Moreover, at the time of defecation, the stool 31 does not adhere to the wall surface of the toilet bowl 6 due to the bubbles and can be completely washed out into the stool tank 13.

In addition, the odor is sucked from the suction port 19 through the odor pipe 25 at the time of urination.

The following is a supplementary description of this odor discharging device with reference to FIG.

That is, one end of the suction pump 26 connected to the odor pipe 25 is connected, and the other end is connected to a glass filter 32 or a ceramic filter 32 having a large number of holes of about 100 microns, water 27 or water. Deodorization tank 28 that stores an aqueous solution for deodorization (for example, water to which a deodorant or the like is added), a pipe 3 for exhausting deodorized air into the room
3 is provided to configure the odor discharge device.

Although not shown, if a hole for discharging a fragrance such as a plant herb is further provided so that the fragrance is discharged after stool use, the odor prevention effect is further promoted.

By the way, when the sick person 9 finishes the urination, the valve 14 is contracted, and as shown in FIG. 8, the valve 14 is accommodated in the recess 12b of the discharge pipe 12 in a flat state and the excrement flowing through the discharge pipe line 12a is attached. It is difficult to do so, and the cleaning water from the hot water supply port 15 will wash away the dirt on the toilet bowl 6 and the rubber tubes 7a, 7b.

By mixing a sterilizing agent into this wash water, the Escherichia coli attached to the toilet bowl 6 and the rubber tubes 7a and 7b are killed,
Be kept clean.

At the same time, in order to clean the buttocks after the toilet, as shown in FIG.
After extending 21a and 21b as shown and spraying warm water like shower on the buttocks and the local area to wash off the excrement and urine,
Hot air is blown from the hot air outlet 18 to dry the buttocks and the local area. Next, when air is injected into the valve 14 and the discharge conduit 12a is closed, wash water (warm water) is supplied from the hot water supply port 15 and the wash water is stored in the toilet bowl 6 and the rubber tubes 7c to 7e. The air inside is discharged,
As shown in the figure, the local part 9b of the sick person 9 is immersed in the wash water accumulated in the toilet bowl 6.

Next, bubbles are generated by the warm air blown from the air outlet 17 into the wash water, and the local portion 9b is washed with the wash water and the bubbles.

Since the air blown out into the wash water of the local area 9b is warm air, the hot water temperature for cleaning is unlikely to drop even when the indoor temperature is low, such as in winter, and the local area of the sick person 9 9b is comfortably washed with moderately warm water.

After cleaning the local part 9b of the sick person 9, the air in the valve 14 is discharged and the discharge conduit 12a is opened, so that the used cleaning water is discharged to the toilet tank 13.

When the used wash water is discharged from the toilet bowl 6, the rubber tubes 7c to 7e are inflated by injecting air, and the valve 14 is inflated by injecting air.

Then, hot air is blown out from the hot air outlet 18 and the sick person 9
Local part 9b of is dried.

FIG. 14 shows the expansion and contraction of each rubber tube 7a to 7e and the valve 14 performed by the control operation from the operation panel 23 in the above-described embodiment of the present invention, the supply of water for cleaning, soap liquid, air, etc. In a flowchart showing various operations in process steps, these controls are properly performed based on a control program of an arithmetic processing unit such as a microcomputer incorporated in the operation panel 23.

After excretion, the rubber tubes 7a, 7b, 7c are inflated by the drive of the air compressor 10a of the air supply / exhaust device 10 and are abutted at the center, but the rubber tubes 7a to 7e are flexible even under tension so that the buttocks 9a do not get out of bed. There is a gap between the rubber tubes 7a to 7e and the toilet bowl 6 in order to hold the container.

However, since the valve 14 is expanded by the drive of the air compressor 10a and the discharge conduit 12a is sealed, the odor can be released from the toilet opening 8 through the through opening 5 without discarding the waste immediately after the discharge. Absent.

After excretion, the backrest 4c of the mat 4 is tilted down again so that the sick person 9 can return to a rest state.

At this rest time, the rubber tubes 7a, 7d and the rubber tubes 7b, 7c, 7e are used to prevent pressure sores (bed sores) in the buttocks by the air compressor 10a and the vacuum pump 10b as shown in FIG.
As shown in Fig. 18, it is possible to prevent the blood circulation in the buttocks 9a from being deteriorated by alternately inflating and contracting and changing the place where the buttocks 9a are supported in a cycle of, for example, every 20 to 30 minutes, and this cycle is shortened. A massage effect is obtained by doing.

At this time, by closing the valve 14, the odor in the toilet tank 13 is not released from the toilet opening 8 through the through opening 5 into the room.

FIGS. 19 (A) and (B) show the expansion of each rubber tube-7a to 7e in the case of imparting such a massage function,
An example of contraction control is shown.

The figure (A) shows only the rubber tubes 7a to 7e taken out, and the figure (B) shows the periodic control for these rubber tubes 7a to 7e. In the figure, "hard" means The section in which the rubber tube is inflated to be in a hard state and the term "soft" is in the section in which the rubber tube is contracted to some extent to be in a soft state.

It should be noted that these controls may be performed by using a microcomputer or the like built in the operation panel 23 and creating a required control mode by a program in advance.

Next, the configuration of the above-described toilet bowl will be described in detail with reference to FIGS. 20 to 21. In each drawing, the same reference numerals are given to the portions corresponding to the configurations described so far.

The toilet tank 13 is composed of a bucket-shaped container 34 and a lid 35, and a lid 3 is attached to a mouth 34a of the container 34 having a handle 36 attached to the side.
It is designed to fit 5 together, and this lid 35
Has an opening 37 for admitting excrement by joining the discharge pipe 12, and an annular protrusion 38 substantially equal to the inner circumference of the container 34 is provided on the back of the lid 35 to join the container 34. To ensure that
At the lower part of the opening 37, a small plate-shaped door 39 that is stored laterally is slidably attached to a door holding guide 40.

Reference numeral 41 is a guide portion having a curved shape slightly wider than the pipe diameter of the discharge pipe 12 provided above the one side edge of the opening portion 37 of the lid 35, and 42 is a lid handle for facilitating attachment and detachment of the lid 35. Is.

Reference numeral 43 is a curved projection provided at one end of the upper portion of the small door 39. A joining member 44 such as a rubber magnet or a magic fastener is attached to the curved surface of the projection 43, and the joining member 44
The joining member 45 made of the same material corresponding to the above is provided on the outer circumference of the discharge pipe 12.

Next, to explain this action, first, in order to set the toilet bowl 13 on the lower part of the bed main body 1, a caregiver holds it by hand or using a carriage (not shown). It is pushed horizontally toward the tip opening of the discharge pipe 12 of the bed body 1.

In this case, the projection 43 with the joining member 44 provided on the lid 35 of the toilet bowl 13 and the guide portion 41 are directed forward.

In this state, if the toilet tank 13 is pushed in, the discharge pipe 12 of the toilet 6
The lower end of the guide pipe is guided by the opening of the curved guide portion 41 provided on the lid 35, and at the joining member 45 provided on the outer periphery of the discharge pipe 12,
The joining member 44 provided on the lid 35 is joined and positioned (21st position)
See FIG.

Further, if the toilet bowl 13 is pushed in, the door 39 of the lid 35 will be discharged to the discharge pipe 12
It is pushed by and slides back along the guide 40, and the lid 35
The opening 37 is opened, and the discharge pipe 12 is fitted into the opening 37 (see FIG. 21 (B)).

In this state, when the sick person 9 on the bed body 1 excretes, the excrement drops from the toilet bowl 6 through the discharge pipe 12 into the container 34 through the opening 37 of the door 39.

On the other hand, when the toilet bowl 13 is filled with excrement and is discarded, the toilet bowl 13 may be pulled out from the bed body 1 toward the front side (lateral direction), contrary to the above.

In other words, if you move the toilet bowl 13 in the opposite direction to when it was set,
Since the joint member 44 of the door 39 is joined to the joint member 45 of the discharge pipe 12, the door 39 is pulled out to the opening 37 side,
The opening 37 is automatically closed.

After that, the caregiver carries the toilet tank 13 to the place where it should be discarded with the handle 36 or by a trolley, and the lid 35 is removed there and the excrement is discarded.

After that, the inside of the container 34 may be washed, covered with the lid 35, pushed again under the floor of the bed body 1, and set at the lower end of the discharge pipe 12.

The bed with a toilet bowl of the present invention described above is intended for, for example, a patient with a serious illness in a private room, and an individual toilet bowl is arranged under the bed. However, in large hospitals, it is expected that multiple beds with toilet bowls of the same type will be placed in one room for the same number of sick people, and a facility for collecting excrement in a common large toilet bowl will be required. It

FIG. 22 shows another embodiment of the present invention for answering such a demand.

In the figure, 1a to 1c are bed bodies of beds with toilet bowls according to the present invention, 46 is a room of an inpatient room or nursing home of a hospital in which the bed bodies 1a to 1c are installed, 6a to 6c are toilet bowls, 12a, respectively. ~ 12c are exhaust pipes, 47a ~ 47d and 48 are exhaust pipes

In this way, the bed with a toilet bowl according to the present invention can be effectively used even in a patient room in which a large number of sick persons are accommodated.

[Advantage of the Invention] The toilet bed of the present invention is provided in a toilet attached to the through-hole of the mat, contracts to open the toilet opening, expands to support the buttocks, and the toilet drain pipe. It is provided with a valve that opens and closes this pipe, and has the following excellent effects.

During defecation, the bed can be opened by contracting the pad while the patient is lying on the mat, and when the bowel is not inflated, the pad can be expanded or contracted to prevent the buttocks from slipping.

In this case, since the pad gives flexibility to the buttocks even when inflated, it cannot completely seal the toilet opening, but since the valve closes the drain pipe, The odor of human waste is not released indoors from the toilet.

In particular, the pad is formed of a plurality of rod-shaped rubber tubes, and the expansion and contraction of these rubber tubes are alternately performed in a fixed order, so that an effective massage effect can be brought to the buttocks of a sick person. .

Also, by forming the valve with a rubber ball and expanding the rubber ball after use to close the discharge pipeline, the odor is discharged into the room because it is shut off from the toilet bowl side in a sealed state. It is possible to eliminate the discomfort caused by the odor.

Further, according to the present invention, when defecation is performed, by closing the drainage conduit with a valve and foaming the inside of the toilet in advance, and defecation in this, feces of any nature (soft stool or hard stool) are obtained. Even if there is, it does not adhere to the toilet bowl and the toilet bowl does not get dirty.

Moreover, since the smell of feces is contained by the bubbles, it does not drift indoors.
