Description

Chiropractic Chair {CHAIR FOR CORRECTING THE SPINE}

The present invention relates to a chair for chiropractic, and more particularly, to escape by repeating the action of stretching the body plate to maintain the physiological curvature (S-shaped curve) to naturally stretch between each section of the spine. The present invention relates to a chair for chiropractic that can cure and prevent spinal diseases by relieving the pain caused by nerve compression of the intervertebral discs, as well as maintaining the balance of the muscles and ligaments of the spine and surrounding tissues and aligning the spine in an ideal state.

The spine is the pillar of the body, located in the center of the spine, the spinal cord that connects the brain to control and regulate all the functions of the body, to support the body's weight, and to send commands from the brain to each part of the body. It functions to protect the spinal cord.

Maintaining the 24 spine bones, pelvis, and skull in place to protect these spinal cords is the basis of health. The spine, which is made up of 24 bones, serves as an intermediate link between the pelvis and the skull.

Also, when each vertebral bone is in place, the spinal cord or spinal nerves work without any obstructions, but when the vertebrae cannot find their place, our spinal nerves, which must pass between these vertebrae, begin to be compressed. Disorders of several nervous systems begin, which can lead to serious disease by reducing the functioning of the body's related organs and by reducing immune function.

There are many causes of this disease, including poor posture, wrong lifestyle, bad exercise, stress, accidents (such as traffic accidents), and heredity. Displacement of is also a cause of various diseases.

In other words, the human spine seen from the side shows a large "S", which acts as a giant leaf spring, distributing weight very well. The human spine seen from the front (front) stretches straight without any curves and balances the left and right.

When these curves and straight lines are broken, their weight now presses on the body with immense stress, causing microscopic displacement of the vertebrae, and the muscles clumped together to support the vertebral bones and the body's weight to press on the spinal or peripheral nerves. This compression causes greater pain, which in turn leads to a vicious cycle of pain that causes further compression.

In other words, most people, including students and office workers, spend a considerable amount of time in their daily lives sitting on a chair, which causes stress on the spine and pelvis and the muscles around them because the upper body loads are transferred to the spine and pelvis. It is accompanied by fatigue or pain.

In addition, when the posture of sitting on a chair is incorrect or the design of the chair is not maintained, a proper seating posture may cause spinal disc disease (lumbar lumbar herniation).

Therefore, the human body maintains the physiological curvature of the spinal intervals while maintaining a natural movement, so press the wrong position of the spine smoothly while stretching the motion through the repetition of the spine to be pressed again to find the place, The pain will naturally decrease. In addition, it helps to maintain correct posture, improve joint mobility, and relieve symptoms such as pain and stiffness.

In general, when the spine is abnormal, the treatment of spine abnormalities by a method of treating the spine by hand, such as acupuncture or physiotherapy, or by hand.

In addition, the spine braces are generally used to straighten the spine by simply stretching the spine upside down the user, the vertebrae, the periphery of the spinal tissue is stretched but the effect of actually extending the spinal node is insignificant.

In particular, the physiological curvature (S-shaped curve) to maintain the body's gravity balance when standing up, it is difficult to obtain a sufficient therapeutic effect, there was a high risk of high-pressure patients.

In addition, there is a bed (tractor) for the spine with a horizontal top plate, the user pulls the user's neck and spine in the longitudinal direction in the lying position, or in the pulled state by shaking the upper and lower body in opposite directions to form a spine There is a bed for vertebrae that corrects the spine by restoring the escaped spinal nucleus in place as the gap between the vertebrae and the vertebrae opens, but this also causes tension of muscles, which is unnecessary spinal tissue, because it is difficult and forced to maintain the physiological curve. There are side effects and the effect of stretching the spinal joints is insignificant.

In particular, the method of tying and pulling on the jaw is a dangerous way to cause a disc of the jaw joint should be prohibited.

In addition, the chiropractic bed is expensive and usually used in a hospital specializing in spine treatment rather than the general use.

Therefore, the present invention was devised to solve the above problems, and by sitting on a chair to lift and lower the body plate maintaining the physiological curvature (S-shaped curve) to repeat the operation to naturally stretch between each section of the spine. The purpose of the present invention is to provide a chair for chiropractic that can treat and prevent spinal diseases.
