Are bent by the floor plates 8 and 9. Thereby, the user can raise the upper body without moving the buttocks located on the third floor plate 7 forward.

The driving section 11 is driven by a wireless remote controller 21. The remote controller 21 is provided with a confirmation switch 22, a back-up switch 23 and a back-down switch 24 as shown in FIG. By operating each switch, a different pulse signal of light, ultrasonic wave or electromagnetic wave is output from the remote controller 21.
As a pulse signal for remote operation, light or ultrasonic waves are more preferable than electromagnetic waves.

The remote controller 21 will be further described. First, as shown in FIG. 1B, operation signals from the switches 22 to 24 are input to the inside of the remote controller 21.
Control unit 26. The first control unit 26 outputs different pulse signals according to the input signals from the switches 22 to 24.

For example, when the confirmation switch 22 is pressed, a confirmation signal is output from the first control unit 26. When the back-up switch 23 or the back-down switch 24 is pressed, a back-up signal and a back-down signal are output as operation signals for controlling the operation of the drive unit 11.

Each signal output from the first control unit 26 is amplified by an amplifier 27 and input to an oscillation unit 28.
Thus, the oscillating section 28 oscillates and outputs signals having different pulse waveforms of light or ultrasonic waves corresponding to the respective signals. In this embodiment, an optical signal is used. Therefore, the oscillating section 28 is provided with a light emitting diode for outputting the optical signal.

Boards 3a and 3b are provided at one end and the other end in the longitudinal direction of the support frame 3 of the bed B, respectively. A receiving section 31 for receiving a signal from the remote controller 21 and a signal from the receiving section 31 are input to one of the board bodies 3a via an amplifying section 30 shown in FIG. A control unit 32 is provided.

As shown in FIG. 2, the second control unit 32 includes a collating unit 33, an input unit 34, a setting unit 35, and an output unit 36.
Having. The collating unit 33 is configured to control the remote control.
The confirmation signal S1 output when the confirmation switch 22 of the camera 21 is turned on is input. In the collating unit 33, the confirmation signal S1 and the setting signal S
2 is compared. If the confirmation signal S1 and the setting signal S2 match, a release signal S3 is output to the output unit 36.

The setting signal S2 is a signal specific to the bed B, and is set to a signal different from other beds (not shown), so that each bed can be differentiated. I have.

Of the signals received by the receiving unit 31,
An operation signal S4 corresponding to the type of operation of the drive unit 11 is input to the output unit 36 via the input unit 34. This output unit 3
Reference numeral 6 denotes an AND circuit (not shown), which includes a release signal S3 from the matching unit 33 and an operation signal S3 from the input unit 34.
4 is input, the drive signal D corresponding to the operation signal is input.
Is output to the drive unit 11. As a result, the drive unit 11 performs a back raising operation and a back lowering operation according to the type of the operation signal.

The release signal S3 is output from the board 3
The data is also output to the display unit 37 provided in a. Display 37
Is constituted by means such as a lamp and a buzzer which can be confirmed visually or audibly. Thereby, the release signal S3 is displayed on the display unit 37.
Is output, it can be recognized that the confirmation signal S1 matches the setting signal S2. That is, the remote controller 21 outputs the unique confirmation signal S1.
The operator can confirm which bed B is driven by the remote controller 21 held by the operator.

Next, the operation of the bed B having the above configuration will be described with reference to FIG.
This will be described with reference to FIG. For example, when performing a back-up operation in order to raise the upper body of the user who is lying on the floor plate 5, as shown in steps 1 and 2 in FIG. The confirmation switch 22 is pressed toward, and then the back raising switch 23 is pressed. As a result, the confirmation signal S1 and the operation signal S4 are sequentially output from the oscillation unit 28 of the remote controller 21.

The acknowledgment signal S1 output from the remote controller 21 is received by the receiving section 31, and then compared with the setting signal S2 by the matching section 33 as shown in step 3. Here, if the confirmation signal S1 and the setting signal S2 match as shown in step 4, the collation unit 33 outputs the
The release signal S3 is output to the display unit 6 and the display unit 37, and if they do not match, the driving operation of the bed B is redone.

If the confirmation signal S1 and the setting signal S2 match, a release signal S3 is output to the display section 37 to indicate the fact. Therefore, the display section 37 is driven by the remote controller 21. The bed B can be confirmed by the operator or the patient. This is indicated by step 4A. Therefore, it is possible to prevent the operator from operating another bed by mistake.

On the other hand, the operation signal S4 output from the remote controller 21 is input to the output unit 36 after the type of the operation signal S4 is determined by the input unit 34. This is shown in step 5.

If the output unit 36 receives the release signal S3 from the collating unit 33, the output unit 36 outputs the drive signal D3 corresponding to the type of the operation signal S4 from the input unit 34.
Is output to the drive unit 11.

As a result, if the driving signal D is a back-up signal as shown in step 6, the motor 1 of the driving section 11
3 is driven in the normal rotation direction, the first floor panel 6 is raised, the upper body of the patient is raised, and the third and fourth floor panels 8,
9 is bent in a mountain shape to hold the leg.

If the driving signal D is a back lowering signal as shown in step 7, the motor 13 is driven in the reverse direction so that the first floor panel 6 falls down, and the third and fourth floor panels 8, 9
Becomes flat.

The raising and lowering operations are usually stopped by operating the limit switch at the stroke end. To stop at the middle position when raising or lowering the back, use the back-up switch 2
3 or by releasing the pressing operation of the back lowering switch 24.

As described above, in the remote controller 21 having the above configuration, the confirmation signal S1 is output by pressing the confirmation switch 22, and the confirmation signal S1 is compared with the preset setting signal S2. Only when these signals match, a drive signal D corresponding to the operation signal S4 is output from the output unit 36 to the drive unit 11, and this drive unit 1
3 is driven.

Therefore, it is not possible to drive the drive unit 13 by pressing the drive switch without pressing the confirmation switch 22, and by pressing the confirmation switch 22, which bed B is driven by the remote controller 21. Can be confirmed. Therefore, since it is necessary to confirm which bed B is to be driven, the bed B is driven and operated.
An erroneous operation due to a mistake in the control of the controller 21 can be reliably prevented.

The present invention is not limited to the above-described embodiment, but can be variously modified without departing from the gist thereof.
For example, in the above embodiment, one remote control is used.
The case where one bed is operated with LA has been described,
The present invention can also be applied to a case where a plurality of beds are driven by one remote controller.

In this case, as shown in FIG. 5, a plurality of confirmation switches, for example, three confirmation switches 22a, 22b and 22c are provided on the remote controller 21A. By pressing each of the confirmation switches, a confirmation signal having a different pulse is output.

On the other hand, on three beds (not shown) operated by the remote controller 21A, setting signals respectively corresponding to the confirmation signals output by pressing the confirmation switches 22a, 22b and 22c are set. ing.

Therefore, even when a plurality of beds are operated by one remote controller 21A, it is possible to operate after confirming the beds to be driven by the respective confirmation switches 22a, 22b and 22c. Therefore, erroneous operation can be reliably prevented.

The present invention can be applied to a bed provided with a height adjusting mechanism capable of adjusting the height of the bed in addition to the back raising mechanism. In this case, an up switch and a down switch may be provided in the remote controller.

[0044]

As described above, according to the present invention, the confirmation switch for outputting the confirmation signal and the operation signal corresponding to the type of operation of the drive unit provided on the bed are output to the remote controller. A drive switch for receiving the operation signal after the check signal and the setting signal match with the checking unit and the checking signal that checks the checking signal and the preset setting signal. An output section for outputting the drive signal is provided in the drive section.

Therefore, not only can the bed driven by the confirmation switch be confirmed, but the bed cannot be driven unless the bed driven by the confirmation switch is confirmed, so that the bed can be remote-controlled. In this way, erroneous operation at the time of remote operation can be reliably prevented.
