Description

Cervical vertebra traction chair physiotherapy support device

technical field

The utility model relates to the field of medical equipment, in particular to a multi-directional cervical traction chair physiotherapy support device with ultrasonic and electric pulse physiotherapy functions.

Background technique

At present, the clinical demand for cervical spine treatment is increasing day by day. The principle of cervical traction is to use external force to pull the cervical segment of the spine and related tissue structures, so as to increase the intervertebral foramen and intervertebral space, reduce the pressure of the intervertebral disc, restore the cervical curvature, relieve the compression of nerves and blood vessels, relieve muscle spasm and pain, It is one of the effective methods for the treatment of cervical spondylosis.

Most of the cervical traction devices on the domestic market use a fixed vertical cervical traction mode, which can only perform force traction on the cervical spine in a single direction, which can only relieve neck muscle spasm. Another patent application of the inventor applies for a cervical traction chair (201420571958.1), which is characterized in that: the head is fixed with a head clamp and a head cover, and the control of the angle is increased on the basis of conventional cervical traction, not only The vertical force traction on the cervical spine also increases the movements of the neck swinging from side to side and the front and back inclination angles, and the combined treatment of traction force, traction time and traction angle can be performed. Practice has shown that the therapeutic effect of this device is significantly improved compared with the existing cervical spine traction devices on the market.

The head is fixed with a head clamp and a headgear. During the traction process, the patient's neck is always in a suspended state. There is no support point for the neck.
