f is provided. Further, the operation panel 8 is provided with a display portion Dp for displaying the posture state of the bottom 5 and for displaying setting information, operation mode and the like.

The controller 9 has a well-known structure, and a procedure for presetting an adjustment angle of the bottom 5, a procedure for bringing the bottom 5 to a specific posture, a back bottom 5a and a knee bottom 5b set in the storage means 11. A procedure for performing or canceling the control operation based on the restriction information on the angle difference between the and is included. Further, the display unit Dp is set to convert the detection signal from the rotation amount detecting means into a signal that can be displayed as position information of the bottom 5 and supply the signal.

Further, the motors 10a to 10c are provided with appropriate rotation amount detecting means (not shown) for grasping, for example, the current state of the bottom 5, that is, position information from the operation amount (rotation amount) of the motor. It is equipped. The detection signal from the rotation amount detecting means is provided to the controller 9 as position information, further provided to the operation panel 8 and displayed on the display unit Dp so that the operator can recognize it as the position information of the bottom 5. .

Next, each procedure incorporated in the controller 9 will be described. First, the controller 9
A procedure for storing the adjustment degree of the bottom 5 in the storage means 11 is incorporated. In this case, together with the memory switch Sm,
The switch Sw corresponding to the position information of the bottom 5 to be stored
By turning on any one of 1 to Sw10,
By activating the corresponding motors 10a to 10c, observing the position information displayed on the display unit Dp, and stopping the ON operation when the desired value is reached, the position information, that is,
The detection signal from the rotation amount detection means in the motors 10a to 10c is stored in the storage means 11 as position information of the bottom 15 according to the desired posture and height of the bottom 15.
I am trying to store it.

Further, by turning on the specific operation start switch Sc in the controller 9, the specific posture (position) of the bottom 5 stored in the storage means 11 is read out, and based on this information, the motors 10a ... Operating power is applied to 10c to bring the bottom 5 to a specific posture. Note that, here, the specific posture (position) of the bottom 5 refers to a cardiac position for providing a convenient posture during rehabilitation, as shown in FIG. In this case, back raising angle: about 60
The knee elevation angle is 15 °, and the reverse extension (Rivest Rendenberg) angle is 15 °, which are stored in the storage unit 11. That is, by turning on the specific operation start switch Sc, the controller 9 reads the operation amounts of the motors 10a to 10c for configuring the Cardiac position stored in the storage means 11, and the motors are read. A procedure for supplying operating electric power to the motors 10a to 10c is set until the operating amounts of 10a to 10c are reached. Then, when the motors 10a to 10c reach the operation amount forming the cardiac position, the supply of the operating power to the motors 10a to 10c is cut off, and the specific operation start switch Sc is set to be off.

Further, the controller 9 has a CPR
By operating the switch Sf, the motor 10 which is a drive source in the back raising mechanism, the knee raising mechanism, and the lifting mechanism.
A, 10b, 10c are supplied with operating power to increase the rotation speed to increase the return operation speed of the back raising mechanism, the knee raising mechanism, and the elevating mechanism to quickly bring the bottom 5 to the minimum floor height and flatten it. I am able to return to the state.

In the bottom motion control system 2 for the bed 1 as described above, each motion of the bottom 5 of the bed 1, that is, back raising, knee raising, height adjustment, extension and reverse extension is performed by an operation. Switch Sw1 on panel 8
This can be achieved by turning on the corresponding switch of Sw10.

Next, in order to set the angles of the back bottom 5a, knee bottom 5b, and foot bottom 5c, which are the movable parts of the bottom 5, the memory switch Sm and the corresponding warm-up switch Sw1 and warm-down are set. The switch Sw2, the lifting switch Sw3, and the lifting switch Sw4 are turned on.

First, at the back-raising angle, on the operation panel 8, the memory switch Sm is pushed and the head-raising switch Sw1 is pushed to activate the motor 10a to operate the back-raising mechanism to perform the back-raising operation. When the back bottom 5a is tilted to a desired angle, the storage switch 11 can store the tilt angle of the back bottom 5a in that state by stopping the ON operation of the memory switch Sm and the warm-up switch Sw1. In this set state, when the arm raising switch Sw1 is turned on for the next back raising operation, the back bottom 5a can raise the back to the set back raising angle. At this time, the position information of the back bottom 5a, that is, the back raising angle can be detected by the rotation amount detecting means in the motor 10a. In the controller 9, the position information of the back bottom 5a by the rotation amount detecting means and the set back raising angle information stored in the storage means 11 are compared, and the back bottom 5a reaches the set back raising angle. When recognizing that this has been done, the operating power to the motor 10a can be cut off and the motor 10a can be stopped.

On the other hand, at the knee raising angle, the memory switch Sm and the raising switch Sw3 are turned on. Further, in the knee raising operation, the lower limit of the knee raising angle can be set. At that time, the memory switch Sm and the suspension switch Sw4 are turned on. It should be noted that the upper and lower limits of the height can be set also in the lifting operation. That is, to set the upper limit of height, the storage switch Sm and the raising switch Sw5 are turned on, and to set the lower limit of height, the storage switch Sm and the raising switch Sw6 are turned on. .

In addition, the operation control system 2 can also store the Gatch state. To store the Gatch state, on the operation panel 8, the memory switch Sm and the head / up switch Sw9 and the head / down switch Sw10 are turned on. That is, the detection signal from the rotation amount detecting means in the motors 10a to 10c can be stored in the storage means 11 as the desired gatch state of the bottom 15 as the position information of the bottom 15. At this time, if the angle limit release switch Sa is operated, it can be freely set regardless of the limit information on the angle difference between the back bottom 5a and the knee bottom 5b set in the storage unit 11. it can. Next, in order to bring the bottom 15 into the Gatch state, the head / elevator switch Sw9 is turned on. As a result, each operation is performed until the stored posture and state are achieved, and the bottom 5 can be easily brought to a desired state. If the angle limit release switch Sa is not operated, the limit information of the angle difference between the back bottom 5a and the knee bottom 5b set in the storage means 11 has priority, and the newly set storage information is set. Regardless, the operation is performed within the limits of the angular difference between the back bottom 5a and the knee bottom 5b.

Then, in order to bring the bottom 5 into a specific posture and a cardiac position, a specific operation start switch Sc
Is turned on, the specific posture (position) of the bottom 5 stored in the storage means 11 is read out, and based on this information, the motors 10a to 10c are supplied with operating power to bring the bottom 5 to the specific posture. be able to. That is, the controller 9 reads the operation amounts of the motors 10a to 10c for configuring the Cardiac position stored in the storage unit 11 by turning on the specific operation start switch Sc, and the motors 10a to 10c.
Motors 10a to 10c until 10c becomes the above-mentioned operation amount.
Supply the operating power to. Then, the motors 10a to 1
When 0c reaches the operation amount that constitutes the cardiac position, the supply of operating power to the motors 10a to 10c is cut off, and the specific operation start switch Sc is turned off. In this way, the specific operation start switch Sc is
When the bottom 5 is brought to the cardiac position, it automatically turns off, so there is no need to keep operating it while the mechanism is in operation, during which the nurse can start another task, and the efficiency is significantly improved. Improve to. If any emergency occurs during the operation, the other switches, that is, the switches Sw1 to Sw10, the memory switch Sm, the angle limit release switch Sa, or the CPR switch Sf are turned on to turn on the card. Since the operation procedure for moving to the ACK position can be released and the bottom 5 can be stopped, this is preferable for safety.

Further, when the patient's condition suddenly changes during use in a back-raised state, knee-raised state or gatched state, the CPR switch Sf is turned on to turn on the back-raising mechanism and knee-raising mechanism. The motors 10a, 10b, and 10c, which are the drive sources in the mechanism and the lifting mechanism, are supplied with operating power to increase the rotation speed, and the return operation speed of the back-raising mechanism, the knee-raising mechanism, and the lifting mechanism is increased to quickly In addition, the bottom 5 can be set to the minimum floor height and can be returned to a flat state.

The operation of the motion control system 2 has been described above. However, the specific posture of the bottom 5 is not limited to the cardiac position, but other convenient positions for treatment, treatment, and rehabilitation. Good. For example, various positions such as a state where the main frame 4 is expanded and the knee bottom 5b and the foot bottom 5c are raised, or a state where the main bottom 4 is reversed and the back bottom 5a is raised are set. You can
