Next, the operation of the apparatus configured as described above will be explained.

The device is used by being moved by wheels 37, 37 and fixed in place at a required location.
A case in which lumbar traction treatment is performed will be explained.

When seating the patient on the device, seat 5
is located at the rear moving end, and the locking claw 2 of the seat 5 is
1 is engaged with a locking pawl 23 on the side of the base 1 to prevent free movement and prevent danger.

The patient is placed on the fixed seat 5 and taken into a sitting position, and the lumbar traction device worn around the patient's waist is attached to the hook 18 of the armrest 17 extending from the slide frame 4. In the case of a patient who cannot sit from the front, the armrest 17 is removed, the patient is seated from the side of the device, and then the traction brace is attached.

The backrest 3 on which the patient's upper body is leaning is adjusted and held at an appropriate inclination angle by operating the reclining mechanism 24, and the chest is fixed to the backrest 3 by a chest brace.

When this preparation step is completed, the solenoid 22 is activated to release the seat 5 into a state where it can freely move relative to the slide frame 4.

Next, the operation section 36 is operated to start operating the traction drive section 8. In addition, when the lumbar region traction is being operated, the traction drive section 26 of the backrest remains in a stopped state and does not operate at all. The reversible motor 9 first rotates forward and threads the sliding shaft 12 forward via the reducer 10, so that the slide frame 4 moves forward.
Generates traction force on the patient's chest brace and lumbar traction brace,
Traction force is applied to the lumbar region of the patient wearing the lumbar traction device.

The sliding shaft 12 is screwed forward, and at the beginning of the screwing, the weight spring 13 does not shrink until the slack in the chest traction and lumbar traction brace is eliminated. When the slack is eliminated and traction force is applied to the patient, the weight spring 13 attached to the tip of the sliding shaft 12 shrinks, and the shrinking state is indicated by the potentiometer 14.
When the load that compresses the weight spring 13 is the traction force applied to the patient and this load reaches a load value preset in the operation unit 36, a signal from the potentiometer 14 is input to the operation unit to stop the reversible motor 9, and after a certain holding time set in the operation unit 36 has elapsed, the reversible motor 9 is then rotated in the reverse direction.

Therefore, by reversing the reversible motor 9, the screw feed of the sliding shaft 12 is switched, and the sliding shaft 12 is screw fed in the opposite direction to the above, and the slide frame 4 is moved by the weight spring 13 or the weight spring 34. It returns to the position where the contraction becomes zero, the reversible motor 9 stops, and the waist traction device returns to a state where no tractive force is applied, completing one cycle of traction operation. By repeating this operation appropriately within the operating time, intermittent traction treatment can be performed on the lumbar region.

Next, a case in which cervical traction treatment is performed will be explained.
Fixing the seat 5 when seating the patient in the device and operating the reclining mechanism 24 to keep the patient's posture appropriate are the same as in the case of lumbar traction described above, but in the case of cervical traction, the seat 5 is The fixation is not released and remains fixed during treatment, and the seat 2
The traction drive 8 is kept inactive.

A predetermined portion of the neck brace worn on the patient's neck is connected to the neck traction device 28, and then the operation of the traction drive unit 26 is started by operating the operating unit 36.

The operation of the traction drive unit 26 for one cycle from the start of operation to the stop is performed in the same manner as the operation of the traction drive unit 8 in the lumbar traction treatment described above, and the operation of the weight detection unit 27 is also performed in the same manner as described above. . That is, when the sliding shaft 32 moves upward, a traction force is applied to the patient's cervical vertebrae via the neck traction device 28 and the neck brace, and when the sliding shaft 31 returns downward, the application of traction force is released. to do.

As described above, in the present invention, the seat part 2 installed on the base 1 can be freely moved in the front and rear directions with respect to the slide frame 4 that moves in the front and back directions with respect to the base 1. It also comprises a seat 5 which is attached so as to be locked in a fixed position. Further, the slide frame 4 is forcibly operated by a traction drive section 8 controlled by a weight detection section 15, and the slide frame 4 has an orthosis hook section 1.
A removable armrest 17 having a diameter of 8 is installed. Furthermore, a neck traction device 28 that is forcibly operated by a traction drive unit 26 controlled by a weight detection unit 27 is installed on the backrest 3 that is installed on the base 1 so that the inclination angle can be changed. The effects of the therapeutic traction device constructed in this manner will be described below.

The entire device has become extremely compact and occupies an extremely small area when installed, making it possible to effectively utilize floor space in hospitals and other facilities.

In addition, since the device is small and compact, it is extremely easy to move and install it, and it is also easy to handle when performing treatment.Furthermore, it is extremely easy to select between lumbar traction treatment and cervical traction treatment as needed. Each method has the characteristic of being able to be carried out accurately with simple operations.

In addition, since the structure is chair-shaped and the patient posture can be selected from various positions, lumbar traction can be performed accurately without feeling anxious in a sitting posture of an appropriately selected angle, improving treatment performance and improving cervical spine traction. When towing the vehicle, it became possible to tow it easily by leaning on the backrest. In particular, for patients who find it painful to extend their lumbar region, traction therapy can be easily performed with the lumbar region in an appropriate flexed position.

In addition, since the structure is such that the lumbar traction brace or neck brace is pulled by the armrest or the neck traction device sliding without using a traction rope that pulls the lumbar traction brace or neck brace, regular traction ropes are not used as in the past. inspection,
This eliminates the need for maintenance such as replacement, reduces running costs, and simplifies equipment maintenance and management.

In addition, since the seat is configured to be freely installed on the sliding frame, the drawback of conventional fixed seats in which the frictional force between the buttocks and the seat is included in the lumbar traction force value is eliminated, and the set traction This allows for accurate traction to be applied to the patient's lumbar spine.

In addition, the angle of the footrest that supports the lower leg can be adjusted freely, so when getting on and off the device, the footrest faces downward without interfering with getting on and off the device, and during traction, it supports the lower leg and puts the patient in a comfortable position, making it easier for the patient to move physically. It promotes relaxation and enhances the traction effect.
