At the same time, it can also be adaptively adjusted according to the actual needs of the patient, so as to maintain the better support and orthopedic function of the neck brace.

[0072] Correspondingly, a dressing pack 206 is also pasted on the support airbag 205, wherein some medicines for assisting the patient's cervical spine treatment can be placed in the dressing pack 206, and some self-heating or self-cooling items (such as some propylene glycol, other hydrogel materials, etc.) can also be placed in it for use in conjunction with the dressing pack, thereby increasing the treatment effect on the patient's neck; and in this embodiment, the dressing pack also adopts a detachable structure setting between the supporting pad body, so as to facilitate replacement and adjustment according to the physical conditions of different patients, to meet the use of different patients, and improve the practicality of the device.

[0073] The method of using the present invention is as follows: after the preparation work is completed, the front half neck support and the back half neck support can be wrapped around the patient's neck through the parent-child Velcro, and then the adhesion position of the parent-child Velcro can be adjusted according to the circumference of the patient's mandible and neck (the length of the parent-child Velcro in this device is set to be long enough) to keep the neck support at an appropriate fastening force; then the position of the mandibular support can be selectively adjusted, specifically, the rotation of the height adjustment knob can be adjusted, and the force generated by the meshing of the adjustment gear and the gear bar set on the fixed shaft can be used to control the opening and closing of the upper and lower mandibular supports of the front half neck support, thereby realizing the upper and lower mandibular supports of the front half neck support. Height adjustment: when it is adjusted to a certain height, by adjusting the teeth on the height adjustment knob and fixing it on the slot on the inner side of the cover, the height can be fixed, thereby realizing height adjustment of the upper and lower jaw supports for the front half of the neck support, solving the problem of large individual differences in the mandible and neck, and having a wider range of applications; finally, in order to make the neck support fit the patient's neck better, the support cushion body can be inflated. Specifically, the airbag can be manually inflated and deflated by squeezing and pressing. By pressing the airbag, the gas in the airbag will enter the support airbag through the inflation tube, and the support airbag will gradually be filled with gas, so that it can better fit the necks of different patients.

[0074] It should be noted that the present invention has a simple structure and is easy to operate. It can use the rotation of the height adjustment knob to control the opening and closing of the upper and lower mandibular supports of the front half of the neck support through the force generated by the meshing of the adjustment gear and the gear bar mounted on the fixed shaft, thereby realizing the height adjustment of the upper and lower mandibular supports of the front half of the neck support; it can also be suitable for patients with different neck lengths to achieve traction on the necks of different patients, thereby improving the comfort and effectiveness of patient use; and the setting of the fence through holes and hollow air holes can facilitate ventilation and perspiration of the neck, avoid the occurrence of skin diseases and pressure sores caused by internal lack of ventilation, and improve the comfort of patients wearing; in addition, the support airbag placed at the position corresponding to the convexity can realize the characteristics of inflation and deflation, and the support airbag in the filled state can fit the physiological structure curve of the patient's neck well and support the patient's head, thereby realizing traction treatment for the patient and improving the patient's comfort.

[0075] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and supplements without departing from the principles of the present invention.
