Description

Body traction device for rehabilitation therapy

The present invention relates to a body traction device for rehabilitation treatment, and more particularly, it can be pulled to enable fine adjustment with appropriate force when pulling the neck and waist of the body for the purpose of rehabilitation treatment of the cervical spine and spine of the body. The present invention relates to a retractable body traction device capable of safe traction, thereby protecting a patient.

In general, necks are stiff, arms and fingers are numb and shoulders are often painful among modern people.

It may simply be caused by muscle pain, poor blood circulation, or stroke, but in many cases it is caused by cervical discs.

There are many causes of cervical discs, but except for cervical discs caused by trauma such as traffic accidents, most people are concerned about a lot, have a bad posture, or concentrate on computer for long periods of time, or get stressed a lot. to be.

Cervical vertebrae are the vertebrae at the top of the spine and the neck of the human body (specifically, the cervix). The seven vertebrae are curved.

The cervical spine has an anatomical structure different from the lumbar spine and the thoracic spine, allowing smooth rotational movements and flexion and extension movements.

In particular, the cervical spine located in the neck area is much smaller than the back and waist, but also has a wider range of motion and more frequent movement than the waist, so it is more susceptible to shock than the back or waist.

More than big

In addition, diseases that cause pain in the cervical spine, cervical sprains, cervical herniation, prolapse, cervical fractures, cervical spinal canal stenosis, posterior ligamentosclerosis, spinal tumors.

Representative diseases most commonly occurring are cervical sprains and cervical herniation.

Cervical sprains (wh), whiplash injury, the muscles or ligaments surrounding the cervical spine are abnormally tensioned or loosened, or the cervical spine is overextended or overflexed by external force, Appears when torsional or axial pressure. In other words, the muscles and ligaments surrounding the neck muscles and cervical spine are stretched or torn and swollen and painful, commonly occurring in car collisions, and can also come from falls and injuries during athletics.

Cervical disc herniation, also known as a neck disk, is caused by degenerative changes in the intervertebral discs.

Usually, there are two types of intervertebral discs that protrude from the cervical spine to stimulate the nerves, and hard discs that stimulate the nerves by growing bones behind the cervical spine.

Cervical intervertebral disc herniation may be caused by trauma or chronic stimulation, and it is easily generated when the cervical intervertebral disc changes after aging.

In addition, acute cases may occur when reading or watching TV for a long time in a distorted posture, and may also occur when the computer is used in a fixed position for long periods of time or when sleeping on a pillow that is too high.

These cervical sprains and cervical disc herniation can physically traction the cervix, releasing the muscles of the stiff or loose muscles and ligaments, and stretch the narrowed cervical intervertebral discs to alleviate the symptoms.

In this case, the cervical traction device is used when a physical method of treatment or rehabilitation is performed without a premise of surgery.

Cervical traction device wears a belt that wraps around the chin and neck in standing, sitting or lying position, and is towed using a constant force.

Most cervical traction devices, however, do not have a constant standard for traction position, direction and traction strength and are towed randomly.

In addition, in the case of patients requiring traction treatment, the cervical spine is different from the normal person in most cases, so if the traction attempts at the same position as the normal person can give the cervical spine.

In particular, due to excessive cervical traction, the neck structure may be deformed to date.

In addition, it is difficult to give proper cervical vertebrae or accurate treatment during towing due to the inability to grasp the appropriate traction strength.
