Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed of a multi-functional type in the field of care and welfare, and more particularly to a bed for preventing bedsores and a bath bed suitable for a care recipient in a bedridden state.

[0002]

2. Description of the Related Art Conventionally, as a bed for preventing bedsores, a so-called pneumatic bed having a cushion mat in which a large number of tubes or closed pads are filled with air is known. Also, when bathing a bedridden caregiver, lower the caregiver from the bed, put it on an electric care lift or a dedicated mobile machine, move it to the bathtub, and then hold the caregiver. I'm taking a bath.

[0003]

However, since the pneumatic bed emphasizes the function as bedding, it is inferior in the stability of support of the floor of the bed, and the care-receiver in a bedridden state can change his / her posture by himself / herself. It has become difficult to do. Therefore, in order to prevent bedsores (pressure sores) of the care receiver, it is necessary to periodically change the position of the care receiver in order to promote blood circulation. In this case, the caregiver must frequently change the posture while holding the cared person's body, which imposes a considerable burden on both the caregiver and the cared person. In addition, when the care receiver is moved to the bathroom etc. while still on the bed, the cushion mat may elastically sway up and down, which may cause discomfort to the care receiver and worsen the medical condition. There is.

In particular, when the floor surface of a bathroom with uneven tiling is moved, the cushion mat vibrates violently, which may make it difficult to move to the bathroom using a pneumatic bed. In addition, when bathing, it is necessary to separately prepare a dedicated mobile machine, which causes new problems in terms of purchasing cost and securing installation space.

Further, when the care receiver is put in the bathtub, a plurality of caregivers must lift the head side and the foot side of the care receiver and take care so that the limbs do not slip, Therefore, caregivers need to be very careful,
It's quite a laborious task. As described above, there has been a problem that a caregiver or the like requires a great deal of labor and time for the posture changing work for preventing bedsores and the assisting work for bathing. The present invention has been made in view of this point, and an object thereof is to eliminate a posture change for preventing bedsores, reduce a burden on a cared person and a carer, and allow a bath to be taken without using a care lift or the like. , To provide beds with a simple structure for preventing bedsores and bathing.

[0006]

Therefore, the bed slip prevention and bath bed according to the present invention is provided with a fixed frame and a rotary shaft at the upper end on one end side and the upper end on the other end in the lateral width direction of the bed, respectively. A plurality of fixed belts and movable belts are alternately arranged and stretched between the shafts, and one end of the movable belts is wound around and rewound on the rotary shaft so that the movable belts can be adjusted in height. The first feature is that it is provided. A second feature is that the length of the movable belt is set to a length such that the spanning portion of the movable belt can be lowered to near the floor surface by rewinding the rotary shaft.

[0007] This bed sore preventive bed is constructed by alternately combining a fixed belt and a movable belt, and periodically moving the movable belt up and down by a motor, thereby changing the belt contact surface of a cared person, so that the skin on a certain part of the skin is fixed. It removes pressure and promotes blood circulation to prevent bed sores. As a configuration for that purpose, in the present invention, the fixed frame is fixed to one of the upper left and right sides in the lateral width direction of the bed, and the rotary shaft is rotatably attached to the other. A motor is connected to one end of the rotary shaft so that the motor can be rotated in both forward and reverse directions. And
The fixed frame and the rotating shaft are installed at almost the same height,
A plurality of fixed belts and a plurality of movable belts are stretched between both members. The number of fixed belts and movable belts does not have to be the same, and varies depending on the width of the belt,
For example, it is preferable that the number is about 5 to 10. Both of these belts are provided so as to be alternately arranged in the longitudinal direction of the fixed frame. In this case, it is not particularly limited whether they are arranged alternately one by one or several ones.

One end or both ends of the fixed belt are detachably attached to a bed support member such as a lower vertical frame so that the care receiver can be supported only by the movable belt. On the other hand, with respect to the movable belt, one end side portion thereof is locked and fixed to the rotary shaft, and the forward and reverse rotation of the rotary shaft allows the movable belt to be wound and unwound. Thereby, the height of the movable belt can be appropriately adjusted according to the winding amount of the movable belt. That is, the height of the movable belt can be made higher or lower than the height of the fixed belt as a reference.

On the other hand, if the bath bed has a fixed belt, the belt is removed in advance, the bath is placed under the bed, and the height of the body-supporting portion of the movable belt is lowered by the motor. It is designed so that a bedridden cared person can be put in the bathtub without lifting. The basic structure of the bath bed is almost the same as that of the bedsore prevention bed, except that a fixed belt is not always required, but the length of the movable belt is set to a certain length or more. . That is, when the movable belt is rewound by the rotating shaft so that the movable belt hangs between the fixed frame and the rotating shaft, the lowermost end of the movable belt that hangs down in a U shape is at least a certain distance from the floor surface. Be able to approach within. This is because the movable belt stops descending in the portable bathtub that is movably arranged below the bed so that the care receiver can take a bath while lying down.

With the above structure, when the bed slip prevention bed of the present invention is used, the height of the movable belt becomes higher or lower than the fixed belt due to the winding and rewinding of the movable belt. For example, when the movable belt is set higher than the fixed belt, the care receiver contacts and is supported only by the movable belt, while when the movable belt is set low,
The care receiver is contacted and supported only by the fixed belt. As a result, the cared person alternately switches the parts of the body that are pressed by the belts, so that bed sores are prevented.

Further, if a bath bed is used, the lower end of the movable belt hangs down into the bathtub below the bed in a U-shape by rewinding the movable belt by the rotating shaft. In other words, the care receiver can take a bath while lying on the bed. This eliminates the need for a nursing care lift and the like, and the labor of the caregiver is greatly reduced.

Both stoppers 9, 1
0 is provided with an insertion port (not shown),
A locking hole (not shown) is formed on the inner surface of the insertion port.

Bearings 11 are attached to the upper ends of the pair of left leg portions 3a and 3b respectively, and a motor 12 operated by a hand switch (not shown) is provided on the upper portion of the front leg portion 3a.
Is provided. The output shaft of the motor 12 can rotate forward and backward through a gear, and a hand switch has a timer (not shown) attached thereto. The start and stop of the motor 12 and the forward / reverse operation can be set by the timer and the hand switch, and the time can be set and the mode can be switched. A rotary shaft 13 for winding the movable belt is mounted between the pair of bearings 11 so as to be rotatable in the forward and reverse directions, and the left metal fitting mounting frame 1 is provided between the intermediate portions of the pair of legs 3a and 3b.
4 are connected. As shown in FIG.
As shown in FIG. 2, the left side fixing belt stopper 15 corresponding to the right side fixing belt stopper 9 is attached to the metal fitting mounting frame 1.
4 are fixed at equal intervals in the axial direction.

A fixed belt 16 having a predetermined width is laid between the right fixed frame 7 and the left rotary shaft 13 at equal intervals, and a one-touch type attachment / detachment device 17 is provided at the right end of the fixed belt 16. It is installed. Detachable device 1
7 has a structure similar to that of a one-touch type attaching / detaching mechanism for a vehicle seat belt. Specifically, the attachment / detachment device 17 is
An openable and closable locking piece (not shown) is provided at the tip end portion, and the locking piece is detachably mounted in the locking hole of the right side stop fitting 9.
On the other hand, as shown in FIG. 3, the left end of the fixing belt 16 is detachably fixedly connected to the left stopper 15 of the metal mounting frame 14.

Further, the fixed frame 7 and the rotating shaft 1
A movable belt 18 having a predetermined width is stretched between 3 and at equal intervals, and the movable belt 18 and the fixed belt 16 are
The books are alternately arranged adjacent to each other. Movable belt 18
Is made of water-repellent and waterproof material so that it can get wet. The length of the movable belt 18 is set to be equal to or longer than a length at which the looped-up portion of the movable belt 18 can be lowered to near the floor surface by rewinding the rotary shaft 13. The right end of the movable belt 18 is detachably fixedly connected to the stopper 10 of the metal attachment frame 8. On the other hand, the left end portion of the movable belt 18 is fixedly connected to the rotary shaft 13 so as to be able to be wound around it via a fixture (not shown).

In order to use the care bed 1 having the above-mentioned structure as a bed, as shown in FIG. 1, the movable belt 18 is set to a height slightly lower than the fixed frame 7 as with the fixed belt 16, and the movable belt 18 is set on the bed. The mattress 21 may be placed on the sheet. Here, when the bed is used, the height of the fixed belt 16 is fixed, but the movable belt 18 is driven by the motor 12 to rotate the rotary shaft 13 in the forward and reverse directions, thereby increasing the height of the movable belt 18. It can be adjusted to both upper and lower sides. For example, when the amount of winding the belt in which the rotation shaft 13 is normally rotated by the motor 12 is increased, the looping portion of the movable belt 18 moves upward according to the amount of winding. Therefore, as shown in FIGS. 4 and 5, the body of the care receiver M is supported only by the movable belt 18.

In order to prevent bedsores in this care bed 1, as shown in FIGS. 6 and 7, it is sufficient to change the support contact portion of the care receiver M with respect to the care bed 1. That is, the movable belt 1 is rotated by reversing the motor 12.
8 and slacken the height of the movable belt 18 to the fixed belt 1
It may be gradually lowered to a position slightly lower than 6. In this way, the care-receiver M who is in a sleeping state can make the mattress 2
1 to slowly ride on the fixed belt 16. As a result, since the care receiver M is supported only by the fixed belt 16, the support contact portion of the care receiver M with respect to the care bed 1 is different from that supported by the movable belt 18. Since the motor 12 used here has a large reduction ratio and good quietness, the cared person M is unlikely to feel uncomfortable.

The switching of the support contact portion of the care receiver M can be performed manually or automatically. For example, in order to carry out automatically, the cared person M is supported only by the movable belt 18 or the fixed belt 16 by presetting the descent stop time or the rising stop time of the movable belt 18 via the timer of the hand switch. Will be done. As described above, the main care bed 1 includes the movable belt 18 or the fixed belt 16.
As a result, the care-receiver M can be supported alternately every set time, so that the region of pressure on the care-receiver M by the belts 18 and 16 is appropriately changed. As a result, the pressure surface for the care-receiver M is regularly changed so that only a specific part of the body is not pressed for a long period of time, and bed sores are well prevented, and a comfortable state is maintained. That is, in the present embodiment, the fixed belt 16 and the movable belt 18 are alternately combined, the movable belt 18 is vertically and automatically moved up and down by the motor 12, and the contact surface of the cared person M is changed to a constant value. It is possible to remove pressure on the site, promote circulation of blood circulation and prevent bed sores.

Next, a case where the care receiver M takes a bath while lying on the care bed 1 will be described. When bathing, switch from automatic operation to manual operation
The movable belt 18 by pulling up
The cared person M is placed directly on top. Then, first, under the care bed 1, the movable bathtub 20 with the caster 19,
As shown in FIG. 9, it may be set below the care bed 1. At that time, the right end of the fixing belt 16 is attached to the attaching / detaching device 1.
Removed from the stopper 9 via the rotary shaft 13
To the left of. At this time, if a thin string is attached to the right end portion of the fixing belt 16, it is convenient to set the fixing belt 16 in the original state.

Next, by rotating the rotating shaft 13 in the reverse direction, the height of the intermediate portion of the movable belt 18 is adjusted to the bath 20.
It may be lowered to near the bottom of the. Then, the care receiver M on the movable belt 18 comes to be immersed in the hot water W in the bathtub 20 while lying down. That is, in this embodiment,
By removing the fixed belt 16 and lowering the movable belt 18 by the motor 12, the cared person M can be bathed in the bathtub 20 placed under the care bed 1 with less labor. Although the movable belt 18 gets wet when taking a bath, it is easy to drain water because the movable belt 18 is made of a material that has good water repellency and is waterproofed here. You can

After bathing, the movable belt 18 and the like are returned to the original state in the reverse order of the above procedure. That is, after pulling the string, the fixing belt 16 is returned to the original state, the duvet 21 is put under the care receiver M, and then the automatic operation is switched to restore the normal operation. In this case, the mattress 21 is thin so that the vertical movement of the movable belt 18 is gently transmitted, and it is preferable to use the mattress 21 having a high heat retaining property and a waterproof treatment on the lower part.

As described above, although the care bed 1 has a simple structure, it can prevent bedsores and can automatically take a bath while lying down. For example, in order to prevent bedsores, a caregiver has traditionally used a care receiver M
It was necessary to change the body position frequently, but this is not necessary in this embodiment. Therefore, the caregiver does not need to hold the care recipient M and change the body position, which saves a great deal of labor and time for both the caregiver and the care recipient M. Moreover, the casters 4 are attached to the legs of the care bed 1, so that the care bed 1 can be easily moved, and there is little swinging up and down during the movement. At the same time, it is not necessary to prepare a lift or a dedicated carrier when bathing, which solves the problems of cost and space. In particular, when the care receiver M is put in the bathtub, the care receiver does not have to lift the care receiver M, so that the physical and mental burden on the care receiver is greatly reduced.

The present invention is not limited to the above embodiment.
For example, in the above embodiment, the bathtub is moved under the bed for bathing, but depending on the size of the bathtub or the bed, the bed may be moved over the bathtub for bathing. is there.
