Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a cervical curvature recovery training device. Background Art

[0002] The phenomenon of the straightening of the physiological curve of the cervical spine in the neck is mostly caused by long-term bad posture or orthopedic system diseases. When a healthy person is standing or sitting facing forward and upward, the neck seems to be straight when viewed from the side; but the cervical spine wrapped in muscles and skin is not straight, but bulges forward to form a curve, which is called the physiological curve of the cervical spine, also known as the cervical arc or cervical arch; at this time, the muscles and ligaments around the neck are in the most relaxed state; due to the influence of various adverse factors, the curvature of the physiological curve of the cervical spine becomes straight, that is, the cervical arc disappears. The specific measurement method is as follows: On the lateral X-ray of the cervical spine, start from the posterior upper edge of the odontoid process downward, connect the posterior edge of each vertebra to form an arc, and then draw a straight line from the posterior upper edge of the odontoid process to the posterior lower edge of the seventh cervical vertebra. The maximum distance from the highest point of the arc to the straight line is the value of the physiological curvature of the cervical spine, called the cervical arch depth or arc chord distance. The normal value for adults is 12+5 mm. If this value is less than 7 meters, the cervical curvature is straightened. Daily prevention is mainly to avoid inducements and maintain a good neck posture.

[0003] It is generally possible to restore the physiological curvature of the cervical spine to normal after it has been straightened. The treatment is mainly physical therapy and surgical treatment. During the patient's postoperative rehabilitation or drug treatment, in order to assist the patient's neck rehabilitation, some patients need to undergo traction and positioning care for their necks to prevent the patient's neck from being injured again during the treatment stage, which would reduce the patient's postoperative rehabilitation effect. At present, a neck guard is usually used to traction and position the patient's neck. By supporting the patient's lower jaw and the back of the head and supporting the patient's shoulders, the patient's neck can be kept in the correct posture. However, the existing neck guard is not easy to adjust the support angle when used. At the same time, when the patient's head is lying flat, there is no way to effectively support the patient's neck. The patient's head is prone to tilt to the left and right, causing the patient's neck to be squeezed, which is not conducive to the recovery of the patient's postoperative neck wound and the cervical curvature. In addition, when the patient's head is normally resting on the pillow, the ventilation effect is poor, which can easily cause skin discomfort and is inconvenient for the patient to use.
