Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed with a toilet that can be used on the bed, and more particularly, to a bed with a toilet that allows a person requiring care to use the toilet stably while sitting on a toilet seat on the bed.

2. Description of the Related Art In a high-welfare society where nursing care and medical facilities are being enhanced, nursing care beds have come to be provided in a wide variety of forms according to the form of nursing care. As one aspect of such nursing care beds, there are nursing beds with toilet bowls, but most of the conventional nursing beds with toilet bowls are simply made by drilling a hole in the center of the floor and installing a toilet bowl in it. rice field. There are also multi-functional and systemized large-scale care beds with toilet bowls that can stabilize the patient's posture during defecation by dividing the floorboards of the bed and tilting them. Not only does it require the removal of sheets, mats, etc., but the patient must lie on his back to relieve himself. There was a problem that a caregiver was always needed when cleaning up. Furthermore, there is a problem that a multi-functional and systematized large-scale care bed with a toilet bowl having complicated mechanisms and devices is expensive and can only be deployed in large hospitals and large care facilities. Furthermore, the problem of the burden on the human body of the person requiring care, such as forcing the patient to defecate in an unstable posture during defecation, has not been solved.

Various proposals have been made in order to solve the problems of the nursing care bed with a toilet as described above. For example, it is possible for a patient who cannot move to defecate in the most natural and comfortable posture that is sufficiently stable in all directions so that he/she can defecate without the need for nursing care while using bedding such as a bedsheet. A "medical bed with a toilet bowl" (Patent Document 1) has been proposed and is a well-known technology. Specifically, the mat that is integrated with the floor support plate of the bed is divided into a backrest part that can be tilted with a support shaft and a footrest part, and the divided footrest part is the width of the patient's waist. The central buttock is divided into three parts parallel to the longitudinal end face of the bed into the left leg outer part and the right leg outer part on both sides. It is possible to tilt and tilt in a mountain shape through the , and when tilting the lowest part of the central inclined part as a fixed support shaft, a rectangular hole made in front of the central upright part has a tilted toilet seat. This proposal is characterized by providing a means for projecting and burying the toilet bowl body having the toilet bowl body from below.

However, the proposal of such a "medical bed with a toilet bowl" involves difficulty in using it because it is necessary to use it in a tilted sitting position, which is different from the normal posture for using it. In addition, since the toilet seat and the toilet bowl are tilted obliquely, there is a risk that excrement may leak out of the toilet bowl along the human body.

In addition to being used as a bed for sleeping, it can also be used as a caregiver for people who are forced to live in bed, such as severely disabled, sick, hospitalized due to an accident, and bedridden elderly. To care about the influence on the surroundings without leaving the bed by changing the shape of the bed into a substantially chair-like undulation by operating a switch at hand without borrowing power or facilitating nursing care of the caregiver. A "bed device for self-help care" (Patent Document 2) has been proposed and is a well-known technology, in which the user can defecate in a relaxed and comfortable posture. Specifically, the bed surface of the hoisting-type bed device automatically rises and falls from a flat shape corresponding to the sleeping posture, and bends and changes into a substantially chair-like shape by operating a switch, etc. A part of the bed surface that supports the lower part of the toilet is configured so that the buttocks of the person are open downward, and the mobile toilet is automatically driven and positioned under this open space, and is raised to a position where it is easy to defecate. This is a proposal composed of

However, the proposed "self-help care bed device" is composed of large-scale and complicated bed movements, and is a mechanism that bends the legs of the person requiring care below the bed surface during use. It forces the caregiver to take an unnatural posture, and since the bed part on which the legs of the person requiring care are placed is folded downward, the space below the bed is always empty. It is necessary to keep it open, and if there is something under the bed, there is a risk that the operation function will stop. There is a problem that it is difficult to deal with different lengths of the thighs of different people.

In addition, a convenient "nursing care bed with a shower toilet" (Patent Document 3) has been proposed, which facilitates the care of a care recipient such as a sick person or the elderly and facilitates the defecation of the care recipient. It has become. Specifically, it has a bed support leg portion that moves up and down, has a lower space portion, and is provided with a mat support frame body. The middle portion of the mat descends from the opening and retreats to the lower surface of the mat support plate to open the opening. The surface is inserted and exposed, the after-use warm water washing/hot air drying unit is activated, the support frame rises further to open the opening, and the middle part of the mat is fitted in the opening and the mat support frame. This proposal is characterized in that the mat is formed so as to stop as the body rises to a desired position, and that the front surface and rear surface of the mat are formed so as to move in an inclined and flat manner.

However, the proposed "nursing care bed with shower toilet" consists of a large-scale and complicated movement of the bed. In addition to forcing the person requiring care into an unnatural posture, it is necessary to keep the space below the bed completely free of anything. Another problem is that the mechanism for bending the legs of the person requiring care below the bed surface is large-scaled, and it is difficult to accommodate different thigh lengths for each person requiring care.

In addition, a convenient "nursing care bed with a shower toilet" (Patent Document 4) has been proposed, which facilitates the care of a care recipient such as a sick person or the elderly and facilitates the defecation of the care recipient. It has become. Specifically, the mat supporting plate and the mat are provided with an opening into which the intermediate portion of the mat is fitted at a position positioned at the bottom portion of the intermediate flat portion of the mat, and warm water is provided below the opening into which the intermediate portion of the mat is fitted. A portable toilet equipped with a washing and hot air drying device is provided, and the middle part of the mat descends from the opening based on the operation of the switch operation part and retreats to the bottom surface of the mat support plate to open the opening. This proposal is characterized in that the portable toilet with warm water washing/hot air drying device is lifted and the toilet seat surface of the portable toilet with warm water washing/hot air drying device is inserted into the opening and exposed.

However, the proposed “nursing care bed with shower toilet” consists of large-scale and complicated movements of the bed, and the legs of the person requiring care are bent below the bed surface when in use. In addition to forcing the caregiver to take an unnatural posture, it is necessary to keep the space under the bed open without any objects. The mechanism for bending the legs of the person requiring care below the bed surface is large-scaled, and there is a problem that it is difficult to accommodate different thigh lengths for each person requiring care.

The applicant of the present application came up with the idea of providing a nursing care bed with a toilet bowl that does not require a multi-functional, systematized, advanced and large-scale device having a conventional complicated mechanism and device. Focusing on a liftable toilet seat, we developed a bed with a toilet bowl that allows a person requiring care to use the toilet while sitting on the toilet seat on the bed, leading to the proposal of the "bed with a toilet bowl" according to the present invention. .

The toilet bowl 30 is positioned above the bed surface 21. The greatest feature is that the person requiring nursing care can relieve himself while sitting on the toilet seat 31 on the bed.
BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a bed 10 with a toilet bowl according to the present invention will be described below based on the drawings.

It should be noted that the bed 10 with a toilet bowl according to the present invention is not limited to the embodiments described below, but is within the scope of the technical idea of the present invention, i. and can be changed as appropriate.

1 to 4 are explanatory diagrams showing an embodiment of a bed 10 with a toilet bowl according to the present invention and a procedure for using it.
A bed 10 with a toilet bowl according to the present invention is composed of a bed body 20 and a toilet bowl 30. The bed body 20 is provided with a reclining function 22 and a toilet seat hatch opening/closing function 25, and the toilet bowl 30 is provided with a toilet lifting device 32. are provided.

The bed body 20 has a bed surface 21 on which a human body can lie at a predetermined height position, a reclining function 22 in which the bed surface 21 rises and falls, and a toilet seat opening in which the bed surface 21 slides to open and close. It is formed with an opening/closing function 25 .

The reclining function 22 provided in the bed body 20 is formed to have an operation structure in which the upper body resting portion of the bed body 20 rises and falls from a substantially horizontal state to a substantially vertical state. As for the specific structure, it suffices to adopt a conventional structure having the same reclining function as in the prior art, and is not particularly limited. Configured aspects are conceivable. It is desirable that the reclining function 22 can be activated at hand via the remote control switch 41 .

The toilet seat hatch opening/closing function 25 provided in the bed body 20 is arranged at the buttocks resting portion located substantially in the center of the bed body 20, and the bed surface 21 automatically opens when the toilet bowl 30 moves up and down. It is formed to have an operation structure in which the hatch 24 is opened and closed by sliding. Although the specific structure is not particularly limited, for example, as shown in the figure, the combination of a drive motor, a chain and a gear built into the bed body 20 on the foot side from the buttocks resting part Configured aspects are conceivable. It should be noted that, as with the reclining function 22, it is desirable that the function 25 for opening and closing the toilet seat hatch can be operated at hand via the remote control switch 41. FIG.

The toilet bowl 30 is formed with a toilet seat 31 on which the buttocks of a human body are placed on the upper part and an excretion processing function 33 on the lower part. The toilet bowl 30 is provided with a toilet lifting device 32. By the toilet lifting device 32, the toilet bowl 30 can be used from below the bed body 20 via the hatch 24 while sitting on the toilet seat from the bed surface 21. It is possible to rise to an upper position where it is possible to add .

The toilet lifting device 32 is provided below the toilet 30 and is formed to have a lifting operation structure. Although the specific structure is not particularly limited, for example, a mode configured by a combination of a drive motor and a pantograph can be considered. It should be noted that the activation of the toilet lifting device 32 is desirably operated by hand via the remote control switch 41 as with the reclining function 22 and the toilet seat hatch opening/closing function 25 .

The excretion processing function 33 is formed to have a structure capable of processing excrement excreted from the human body. Although the specific structure is not particularly limited, it is conceivable to adopt means for direct connection to the sewage system 42 as shown in FIG. 2, for example. By adopting such a mode, excrement excreted from the human body flows directly into the sewage system 42, so that the bed 10 with a toilet bowl that is always clean and hygienic can be provided without the excrement being retained. .

As for the specific structure of the excrement processing function 33, it is conceivable to employ means for storing excrement in a portable tank 43, as shown in FIG. By adopting this aspect, it is possible to provide the bed 10 with a toilet bowl that is structurally simple and inexpensive.

Regarding the excretion processing function 33 of the toilet bowl 30, whether to select means to be directly connected to the sewage system 42 or means to be stored in the portable tank 43 is appropriately determined based on the installation environment such as a hospital, a facility, or an ordinary home. It is selected.

A series of operating conditions of the bed 10 with a toilet bowl according to the present invention, which is composed of the above constituent elements, will be described in order with reference to the drawings. FIG. 3 is an explanatory diagram showing the procedure for using the bed 10 with a toilet bowl according to the present invention.

First, the human body assumes a supine posture on the bed surface 21, and in this state, the toilet seat opening/closing function 25 provided in the bed body 20 is operated, so that the bed surface 21 at the buttock resting portion slides. The elevator door 24 opens (see FIG. 3(a)).

When the elevator door 24 opens, the toilet lifting device 32 is activated, and when the toilet 30 rises and the toilet seat 31 reaches the same height as the bed surface 21, the lifting stops (see FIG. 3(b)). ). This action brings the buttocks of the human body into contact with the toilet seat 31 .

Next, by activating the reclining function 22 of the bed body 20, the position where the upper body is placed starts to rise and fall from a substantially horizontal state to a substantially vertical state (see FIG. 3(c)). By this action, the upper body of the human body is raised from the supine position to a substantially vertical position.

Finally, when the position where the upper body of the bed body 20 is placed becomes substantially vertical due to the ups and downs, the toilet lifting/lowering device 32, which had been temporarily stopped, is activated again, and the toilet 30 is seated on the toilet seat from the bed surface 21. ( see FIG. 3(d)). By such motion, the buttocks of the human body rise as the toilet bowl 30 rises, the upper half of the body also rises along the substantially vertically undulating bed surface 21, and the legs also rise while bending at the knees.

By performing the series of operations described above, it is possible to relieve oneself on the bed surface 21 in the same sitting posture as sitting on a normal toilet bowl 30 (toilet seat 31).

The reason why the toilet bowl 30 is lifted again by the toilet lifting device 32 after the upper body resting portion of the bed body 20 is raised and lowered to a substantially vertical state is that the bed body 20 is still tilted at an angle. This is because if the person is raised, the buttocks of the human body will be pushed upward, and the upper half of the body will not be raised substantially vertically, and the waist will be in a floating state.

The reason why the toilet seat hatch opening/closing function 25 and the toilet bowl lifting device 32 are operated before activating the reclining function 22 in the above series of operation situations is that the toilet seat hatch opening/closing function is performed after the upper body of the human body is raised substantially vertically. If the function 25 is activated, the hatch 24 will open before the toilet seat 31 rises to the same height as the bed surface 21, and the buttocks will fall into the hatch 24. is.

When the toilet is finished, the bed body 20 is returned to its original state. As for the series of operations when returning, the above operation situation may be reproduced in reverse. That is, the toilet bowl 30 is lowered by the toilet lifting device 32, and when the toilet seat 31 reaches the same height position as the bed surface 21, the lowering is temporarily stopped. The toilet bowl 30 is tilted to a horizontal state, and the toilet bowl lifting device 32 lowers the toilet bowl 30 again.

By the way, regarding the series of operations of the above-described bed 10 with a toilet bowl, it is possible to employ a mode in which the operation is automatically performed up to the final form by simply pressing an operation button provided on the remote control switch 41 or the like once. That is, the remote control switch 41 or the like is provided with an operation button for toilet ON and toilet OFF, and the user simply presses the toilet ON operation button once to automatically operate the above series of operations to the end, and the bed 10 with toilet bowl is operated. is ready to use, and conversely, the toilet-bed 10 returns to its original state by pressing the toilet OFF operation button once. FIG. 4 is an exemplary schematic diagram showing an embodiment of the remote control switch 41 having the operation buttons.

The toilet bed 10 is provided with a control device 40 for controlling the automatic operation of the series of operations in order to adopt a mode in which the series of operations described above is operated by pressing the operation button once. With this control device 40, the reclining function 22, the toilet seat hatch opening/closing function 25, and the toilet lifting device 32 are not individually operated. It can be activated into form.

The bed with toilet bowl 10 according to the present invention configured as described above is composed of simple functions and devices such as a reclining function 22, a toilet seat hatch opening/closing function 25, and a toilet lifting device 32. The toilet bowl 30 is raised to a position above the bed surface 21 by the toilet bowl elevating device 25 so that the user (person requiring nursing care) can lift the toilet seat on the bed surface 21 in the same manner as a normal toilet bowl. Since the toilet can be relieved while sitting on the toilet 31, the toilet can be stably relieved without any sense of incongruity, and excrement does not leak out of the toilet bowl, so that the surroundings do not become dirty. It is possible to provide the bed 10 with a toilet which reduces the physical and mental burden, is easy to operate, and can be installed in any environment.

The bed with a toilet bowl of the present invention employs a simple structure to contribute to cost reduction and reduce the physical and mental burden on the user. Since it can be installed in any environment, it is considered that the industrial applicability of the "bed with a toilet bowl" according to the present invention is extremely large.
