Description

The present invention belongs to the technical field of medical equipment.

In the related art, there is a method in which a rotating chair and a footrest are integrally rotated, and a waist is rotated by grasping an externally provided fixed handle.
61-36625

There are the following problems in the conventional device.
That is, in the conventional product, the stimulus to the muscle by the repetition of the left and right torsion action by the rotation motion of the waist removes the congestive state and promotes the blood flow. It can correct the lumbar spine and prevent and treat "gummy waist" and "herniated disc".
However, with conventional instruments, only the lower body muscles are strongly pulled unilaterally, and when used as a preventive method for lumbar waist and intervertebral disc herniation, if the muscles are stiff, a one-sided strong twist from the lower body will occur. Traction can damage the tendon, and if suffering from the above symptoms, pain may occur along the running of nerves emanating from the lumbar spine. In addition, the correction of the thoracic spine and the exercise of recovering the fatigue of the back muscles of the upper body could not be sufficiently performed, and it was not enough to improve the functions of internal organs and promote the blood flow of the whole body.

The present invention has been devised to compensate for such disadvantages, and the purpose is to correct the lumbar spine and the thoracic spine by rotating the upper body and lower body mutually in opposite directions around the waist. It is an object of the present invention to provide a chair-type spine corrective health instrument which can be simultaneously applied relatively easily.
For this purpose, the angle setting of the chair-type spine corrective health appliance is such that an arbitrary angle is set to half the angle required for traction and twisting of the lumbar region. Due to the rotation of the upper body, traction and torsion are performed from the waist to the muscles at the back of the shoulder and the base of the arm, and at the same time, the lower body is reversely rotated to perform traction and torsion of the muscle from the waist to the knee. The upper body and lower body each receive the same amount of traction and torsion in the muscles with the same light stimulus, and the repetitive movements cause the spine to twist to the left and right, and at the same time make the rigid muscles flexible throughout the back.
That is, the reason why the spine can be corrected is that the lumbar spine is corrected by the rotation of the lower body, by sitting on a chair type spine correction health device, fixing both arms to the armrest, and in this state the upper body rotates counter-rotating with the lower body, Rotation of the upper body will perform thoracic spine correction.

In order to achieve the above object, the chair type spine corrective health device is rotatably provided on the main body (1), and includes a turntable (3) for a seat on which a lower body is seated, and a turntable (2) for an upper body for fixing the upper body. Can perform a predetermined correction on the human body by reciprocally rotating by a predetermined angle in opposite directions to each other.

The chair-type spinal orthodontic appliance has a backrest (5) for fixing the upper body, and both armrests (4a) and (4b). The upper body was easily twisted.

The power switch (18) and the timer switch (19) are attached to the armrests of the chair-type spine corrective health device to improve the convenience of operation.

The chair type spine corrective health appliance stops the rotation for a predetermined time at a predetermined angle in one direction when rotating the rotating disk for seating (3) and the rotating disk for upper body (2) in opposite directions, and then The apparatus is characterized in that it is stopped for a predetermined time when it is rotated by a predetermined angle in the other direction, and thereafter, this operation is repeated.

The chair-type spine corrective health appliance is characterized in that the height of the seat turntable (3) is adjustable.

The chair-type spine correction health appliance is characterized in that the rotation speed can be adjusted when rotating the rotating plate for seating (3) and the rotating plate for upper body (2) in mutually opposite directions. .

Due to the relative rotation of the upper body and lower body turntables centered on the waist as described above, the oblique traction of both muscles from both sides and the left and right torsion, half the rotation angle required when correcting only with the lower body That is, the stimulation given to the muscle is also slow.
Muscles need stimulation because the skeleton itself does not work to move, the muscles are attached to the bones via tendons, and the skeleton moves due to the expansion and contraction of the muscles, so the muscles involved in correcting the spine are flexible. Stimulation is required.
When twisting the spine and twisting the spine to the left and right to correct the spine, a large angle rotation or traction only in the lower body is likely to damage the tendon, but repetitive traction exercises that apply gently from different angles to each other are overstimulation. There is no stiffening condition. When the deep, thin muscle layers heat up and improve blood flow and become more flexible, the deep erector spine muscles that connect the vertebrae return to normal elasticity, thus distorting the spine. Is naturally corrected, and as a result, the spine is corrected.
Also, when the muscles in the entire back are subjected to left and right torsional movements, a part of the large back muscles that stop around the front of the humeral head start from the waist and the main muscles in the lower body. Some parts are located at approximately the same position as the origin of the upper body muscles. This position allows the chair to sit on a chair-type spine corrective health device and fix both arms to the armrests, so that the relative rotation of the chair starts and at the same time, the muscles from the lower back to the knees are pulled by the lower body. The lumbar spine is corrected by the torsional action, and the rotation of the upper body is towed and twisted from the waist to the diagonally upper part around the front of the humeral head. By the repetitive action, the erector spinae muscles become flexible, and the effect of correcting the thoracic spine is further enhanced.
Therefore, as described above, the vertebrae return to the normal position with the flexibility of the muscles, and as a result, the spine can be corrected smoothly with slow stimulation. At the same time, the spinal nerves function normally, and the functions of the heart, liver, lungs, digestive organs, kidneys, etc., which are controlled by these nerves, are promoted, metabolism becomes active, and the ability to heal local lesions Will be increased.
In addition, the torsion exercise of the upper body strongly stimulates the muscle group of the upper abdomen and the side abdomen, and promotes the action of decomposing fat, can be expected to be slim, and at the same time, has a favorable effect on diabetes, heart disease and the like.
The device of the present invention is of a chair type, with both arms resting on armrests, has the advantage of a simple overall structure and is easy to carry, and can be used while watching TV and in a family meeting.
