Explaining the block diagram showing the electrical configuration of FIG. 6, a start or stop instruction signal output in conjunction with the start and stop of the traction machine 2 is input to the microcomputer section 32 of the gudge bed 1. The signal given by the operation switch 33 reaches the microcomputer 32 for information conversion, and the signal output from the microcomputer 32 passes through the back speed controller 34 and the back overload protector 35 to extend and retract the back actuator 11. The maximum speed is controlled when starting and gradually decreasing when stopping, and the maximum speed is controlled. Further, a signal output from the microcomputer unit 32 passes through a leg speed controller 36 and a leg overload protector 37 to gradually increase or decrease the leg actuator 13 and control the maximum speed. A signal obtained by a back angle sensor 38 provided on the back seat 5 for detecting the angle of the seat 5 reaches a microcomputer unit 32 via a back amplifier 39 and a back A / D converter 40.

An alarm sound such as a buzzer sound is generated when an abnormality occurs, and the emergency stop switch 48 is a push button switch to be held in the patient's hand and serves to stop the operation of the microcomputer unit 32 in an emergency. When the switch 48 is pushed when an abnormal situation occurs in the patient or when an abnormal situation occurs in the apparatus of the embodiment, the operation of the back and leg actuators 11 and 13 is stopped, and at the same time, the movement of the rope 24 of the towing machine 2 is also stopped. Stop. Although illustration is omitted, when the back, thigh, and lower leg seats 5, 7, 58 are returned to the bed when the back, thigh, and lower leg seats 5, 7, 58 are attached with pressure-sensitive surface switches on the backs of the seats. It is also possible to perform the above-mentioned emergency stop when a foreign object is sandwiched between the frame 3 and each of the sheets.

An instruction signal is given from the microcomputer section 32 via the solenoid controller 50 to the solenoid 49 for fixing the movable frame 4 in the movable state. The solenoid 49 is fixed to the moving frame 4 and the pin 51 is connected to the solenoid 49. When the solenoid 49 is not magnetized, the pin 51 is inserted into any one of the holes 52 provided in the bed frame 3 and fixed. . When the solenoid 49 is magnetized, the pin 51 is pulled out from the hole 52 to make the movable frame 4 movable. The moving frame 4 is in a movable state during the traction treatment in which the traction machine 2 is operating, and while the traction machine 2 is not operating, the solenoid 49 is in a non-magnetized state and the pin 51 moves forward. It enters the hole 52 and is in a fixed state. The storage device 53 stores the set angle value input to the microcomputer unit 32 by the manual switch 23. That is, when the operator first turns the back seat 5 and the thigh seat 7 with the manual switch 23, the tilt angle of the back seat 5 and the tilt angle of the thigh seat 7 are automatically stored in the storage device 53. It Once memorized, the memory is saved even when the power is turned off, and when reused, the back / thigh seats 5 and 7 are automatically raised so as to reach the same set values. The stored value is updated by resetting using the manual switch 23. In FIG. 6, reference numeral 55 is a noise filter, 56 is a power source for supplying power to the back / leg actuators 11 and 13, 57 is a power source for a control circuit to be supplied to electronic components for control, and 60 is a back seat for the abdomen of the patient. It is a belt fixed to 5.

In using the embodiment, first, the patient is placed on the flat gudge bed 1, the waist brace (not shown) is attached to the waist, and the side brace (not shown) is attached to the side, and the gadget bed 1 is set. The tip of the rope 24 of the towing machine 2 is hooked on the waist brace. Next, the towing machine 2 is started, but at the same time as the starting, a start signal is input from the towing machine 2 to the gudge bed 1, and the gudge bed 1 becomes in an operating state. The back raising switch 28 is operated to rotate the back seat 5 to make an angle, and the leg raising switch 30 is operated to rotate the thigh seat 7 to make an angle and raise the lower leg hinge 10 to raise the thigh seat. 7 and the lower leg sheet 58 are chevron-shaped in side view. When the angles of the back seat 5 and the thigh seat 7 are manually set in this way, the set values are automatically stored in the storage device 53, and when the traction treatment is started from the next time, the back seat 5 and the thigh seat 7 are automatically set. 7 rotates to reach the tilt angle set this time.

The back and leg actuators 11 and 13 are controlled by the microcomputer unit 32 to perform a gradually increasing and gradually decreasing operation. That is, taking the back actuator 11 as an example, the actuator 11 has a gradual increase stroke for about 1.25 seconds at startup, a constant speed extension stroke, and when the back seat 5 comes 5 degrees before the set angle. The back seat 5 reaches the set angle by extending through the steps of a 0.9 second gradually decreasing extension step, a low speed extension step, and a 0.3 second deceleration extension stop step. The time required for the constant speed extension process is determined by the value of the set angle of the back seat 5. When the tilted back seat 5 is returned to the original horizontal state, the back actuator 11 is set to the gradual deceleration stroke, the constant speed degeneration stroke for about 1.25 seconds at the time of starting, and the back seat 5 degrees before the zero angle. When it arrives, the back seat 5 is brought into a horizontal state by retracting after going through the steps of a 0.9 second gradual retraction stroke, a low speed retraction stroke, and a 0.3 second deceleration retraction stop stroke.

Since the leg actuator 13 also moves in the same manner as the back actuator 11, its explanation is omitted. The display 16 displays the inclination angles of the back seat 5 and the thigh seat 7 and the calculated waist angle in real time as the back seat 5 and the thigh seat 7 rotate. When the towing machine 2 is started, the solenoid 49 is activated and the moving frame 4 is changed from the fixed state to the movable state. As the cord 24 is retracted, the slack of the side brace that prevents backward movement of the patient's armpit is released, the spine of the patient is extended, and the moving frame 4 moves slightly backward. When the operation of the towing machine 2 is completed, a stop signal reaches the cage bed 1, the inclination angles of the back seat 5 and the thigh seat 7 automatically reach a flat state of zero, and when the flat state is reached, the moving frame 4 automatically moves. It will be in a fixed state, making it safe for patients to get on and off. When “single” is selected with the selection switch 22, the tilting of the back seat 5 and the thigh seat 7 and the turning of both seats 5 and 7 to the horizontal state are not interlocked with the towing machine 2 and are not operated by the operator. The automatic switch 25 is operated each time the vehicle is pulled, and the seat release switch 27 is also operated.
