DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lumbar spinal cord stretcher having a novel structure.

[0002]

2. Description of the Related Art Conventionally, back pain has been treated as follows. 1. Under the guidance of a doctor, wear a corset between the waist and the abdomen to reduce the vertical load on the intervertebral disc,
Trying to reduce back pain. (First method) 2. In a hospital, the patient sleeps on a bed, fixes the patient's upper body toward the head of the bed, and pulls the waist in a direction toward the foot of the bed. (Second method) That is, a band is fixed to the patient's waist, and a belt and a wire attached to both sides of the band, a small electric winch attached to the lower side of the bed via a pulley, etc., according to the condition of the patient. A pulling force of about 30 kg to 40 kg selected in this manner is applied to the lumbar spinal cord. In this case, the action of various patterns, such as releasing for 10 seconds after towing for 10 seconds, is repeated.

[0003]

The above-mentioned prior art has the following problems. 1. In the case of the first method, it is difficult to move the body freely while wearing the corset, and the load of the upper body on the intervertebral disc cannot be sufficiently reduced. Moreover, it must be used for a long time and a long time. 2. In the case of the second method, it is necessary to go to the hospital each time, and it is painful for back pain. That is, once a day, 5 minutes a week, 10 minutes to 20 days
Good results cannot be obtained with just a minute of outpatient treatment, and it is, of course, extremely difficult to balance outpatient work with work. People with low back pain do not go to the hospital until the pain has progressed to a certain extent, and there is often no means to alleviate low back pain at home or the like, so the condition often worsens. In addition, the background of low back pain is diversified as low back pain of drivers such as long-distance trucks, low back pain due to the same posture for a long time due to OA, low back pain due to elderly care by an aging society, and low back pain caused by lack of exercise. It is. The present application has been made in view of such problems of the conventional technology, and an object of the present invention is to provide a device that can solve the above-described problems.
