Neck function trainer

Abstract

The invention relates to a neck function training device. A motor rotates in the forward direction to generate first traction force, the generated first traction force is unloaded when the motor rotates in the reverse direction, the first traction force faces the rear upper position of the head of a user, and a head support is arranged and is used for supporting the head of the user and then acting on the neck of the user. The neck function training device also comprises a cervical vertebra curvature correction model which is arranged on the rear neck of the user, and when the first traction force is applied to the neck of the user, the cervical vertebra curvature correction model plays a role in supporting the cervical vertebra. The neck function training device also comprises a controller which is used for controlling the rotation motion of the motor; the motor is in transmission connection with the head support; the first traction enables the head support to move along the first traction direction; when the motor rotates in the opposite direction, the head support moves along the first traction unloading direction; and an included angle between the first traction force and the horizontal supporting force of the cervical vertebra curvature correction model for the cervical vertebra is an obtuse angle. The neck function training device is used for physiotherapy of nerve-root type cervical spondylosis, and is also suitable for prevention and treatment of cervical spondylosis with other symptoms, and an effect is good.

Description

technical field [0001] The invention relates to a neck function trainer, which belongs to the field of rehabilitation equipment. Background technique [0002] Cervical spondylosis, also known as cervical syndrome, is a general term for cervical osteoarthritis, hypertrophic spondylitis, cervical nerve root syndrome, and cervical disc herniation. It is a disease based on degenerative pathological changes, mainly due to long-term strain of the cervical spine. , Bone hyperplasia, or intervertebral disc prolapse, ligament thickening, resulting in cervical spinal cord, nerve root or vertebral artery compression, a series of clinical syndromes of dysfunction. It is manifested as cervical intervertebral disc degeneration itself and its secondary pathological changes, such as vertebral instability and loosening; nucleus pulposus protrusion or prolapse; bone spur formation; ligament hypertrophy and secondary spinal canal stenosis, etc., which stimulate or compress the Adjacent nerve ...

AI Technical Summary

Problems solved by technology

Reducing the pressure of the head on the cervical spine is a common method. At present, the usual method is: 1. Manually stretch the traction belt through the traction belt to cover the lower jaw and the back of the neck. During the traction process, there will be severe setbacks and shaking, which will easily cause damage to the cervical spine; 2. At present, there is an electric traction chair on the market that uses an electric push rod to drive the traction belt up and down. The push rod is not suitable for continuous long-term continuous work; these two cervical traction devices have three common disadvantages, one of which is the traction direction. For the front and upper part of the head, this kind of single suspended traction can only make the curvature of the cervical spine change from anti-bow to straight at most, but cannot change the curvature of the cervical spine from straight to normal; the second is static traction, only traction, and the third is only applicable to Nerve root type cervical spondylosis, the effect of treatment and prevention of cervical spondylosis is very unsatisfactory
