Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an elderly person, a patient with dementia,
The present invention relates to an electric bed having a mischievous operation prevention function capable of preventing a mischievous operation by a child.

[0002]

2. Description of the Related Art At present, Japan is facing an unprecedented aging society, and the number of elderly patients who are hospitalized for a long time is increasing. Many elderly patients suffer from dementia, which is a great burden for nursing care.

Recently, in hospitals, the labor shortage of nurses, caregivers, etc. is becoming more serious.
For equipment and facilities, automation and simplification of maintenance are being promoted so as to save time and effort. For example, a bed that is electrically operated and has a floor undulating function and a floor lifting function has already been widely adopted. Especially when such an electric bed is applied to the elderly and patients with dementia, the operation switches SW for operating the undulation of the floor and the raising and lowering of the floor are provided so that the patient does not operate the switches. It is preferable in terms of safety to form an operation panel P on the outside lower part of the board that cannot be reached so that only a caregiver or a nurse can operate it (see FIG. 5).

[0004]

However, for example,
Even if the operation switches SW are arranged on the lower outside of the board that is out of the reach of the patient, the electrically operated bed can easily operate the floor with the operation buttons, so that the caregiver can take a look away. There is a concern that the patient will operate it, and especially if the patient with dementia or a child carelessly operates it, it becomes extremely dangerous. The present invention has been made from such a point of view, in addition to the operation button, the undulation of the floor, by preventing the lifting operation can not be performed without pressing the auxiliary operation button, elderly people, dementia patients, It is an object of the present invention to provide an electric bed having a mischievous operation prevention function capable of preventing mischievous operation by a child.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is intended to perform floor undulation and floor elevation in an electric bed equipped with a floor undulation mechanism or a floor elevation mechanism. The operation button for each purpose and the auxiliary operation button are provided, and the floor portion can be raised and lowered by vertically operating the auxiliary operation button together with the operation button for each purpose.

[0006]

In order to raise and lower the floor, the auxiliary operation buttons must be operated in addition to the purpose-specific operation buttons. Therefore, it is possible to make the mischievous operation of dementia patients and children difficult.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an electric bed having a tampering prevention function according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. In Figure 1, bed 1
Indicates. This bed 1 is equipped with an electric floor undulating mechanism and an elevating mechanism (not shown) especially for elderly people and patients with dementia. On the lower surface of the footboard 2, an operation panel for operating the floor undulating mechanism and the elevating mechanism, that is, a bed control panel 3 is provided. As shown in FIG. 2, the bed control panel 3 includes back-raising operation buttons 4, leg-raising operation buttons 5, and floor-raising / lowering operation buttons 6 as purpose-specific operation buttons for raising and lowering the floor and raising and lowering the floor. Is provided. Further, the bed control panel 3 has an auxiliary operation button 7 with the left hand.
An auxiliary operation button 7R with L and right hand is provided.

The operation command signals from the back-raising operation button 4, leg-raising operation button 5, floor raising / lowering operation button 6, and auxiliary operation buttons 7L and 7R are provided on the bed 1 as shown in FIG. This is a configuration introduced into the control circuit 9 mounted on the control box 8. When raising the back, the control circuit 9 has a back raising operation button 4
When the auxiliary operation buttons 7L and 7R are turned on together with turning on, the back raising motor 10 is set to be turned on. Further, the control circuit 9 is set to turn on the auxiliary operation buttons 7L and 7R and to turn on the leg-raising motor 11 by turning on the leg-raising operation button 5 when the leg is raised. ing. Further, the control circuit 9 is set to turn on the auxiliary operation buttons 7L and 7R and to turn on the floor raising / lowering operation button 6 to turn on the raising / lowering motor 12 when raising / lowering the floor portion. As described above, the operation signals from the back-raising operation button 4, the leg-raising operation button 5, and the floor-lifting operation button 6 are accepted only when both the auxiliary operation buttons 7L and 7R are turned on.

With the above structure, the caregiver
Go to the bed control panel 3 on the bottom of the footboard 2 and press the auxiliary operation button 7L with your left hand and the auxiliary operation button 7R with your right hand, and the desired back-raising operation button 4 or leg-raising operation button 5 or floor lifting operation. By pressing the button 6, the floor of the bed 1 can be lifted and lowered. In this way, the back raising operation button 4, the leg raising operation button 5, and the
Further, the operation signal from the floor raising / lowering operation button 6 is accepted, and the desired floor raising / lowering and undulating operations can be performed. Therefore, it is unlikely that a dementia patient or a child can easily perform the above operation, and it is possible to prevent the mischievous operation.

The bed control panel 3 described above is used.
In the above, the operation buttons may be arranged as shown in FIG. That is, the auxiliary operation buttons 7L, 7R are set on the bed control panel 3 by raising the back operation button 4,
It is also possible to dispose them on both sides of the leg raising operation button 5 and the floor part raising and lowering operation button 6.

With the bed control panel 3 as well, the auxiliary operation buttons 7L and 7R must be pressed before operating the back-raising operation button 4, leg-raising operation button 5, and floor-lifting operation button 6, I don't think it can be easily operated by dementia patients or children,
Mischievous operation can be prevented.

Although the electric bed having the tampering prevention function according to the present invention has been described with reference to the embodiments, it is a prerequisite that both auxiliary operation buttons 7L and 7R are turned on. The control circuit 9 is set to memorize that the auxiliary operation buttons 7L and 7R are turned on so that the auxiliary operation buttons 7L and 7R can be continuously operated without operating the auxiliary operation buttons 7L and 7R at the same time. With this setting, you can operate with one hand. Therefore, the operation can be performed even with an object held in one hand, and the characteristic that the dementia patient or the child cannot easily operate is not impaired. In addition, auxiliary operation buttons 7L, 7R
It is also possible to further increase the number and set to operate continuously.

[0013]

As described above, according to the present invention, in order to move up and down the floor, the auxiliary operation buttons as well as the purpose-specific operation buttons must be operated. Therefore, it is unlikely that a dementia patient or a child can easily perform such an operation, and the mischievous operation can be made difficult.
