Description

A device for measuring the left and right rotation angle of human head and neck

technical field

The utility model relates to the field of medical testing instruments, in particular to a measuring device for the left and right rotation angles of the head and neck of a human body.

Background technique

Due to factors such as bone structure and cervical vertebral artery course in some people, vertebral artery compression or even occlusion will occur when the head and neck rotate to the left or right. The left and right rotation angles of the head and neck of different people will be different, and The size of the rotation angle is closely related to the compression and occlusion of the vertebral artery. By measuring the left and right rotation angles of the head and neck of the human body in the supine position, we can observe the changes in the blood flow rate of the vertebral arteries in the human neck, and record the angle when compression and occlusion occur, so as to prevent the head and neck from being too large in left and right movement angles or sleeping postures, etc. It is very necessary to cause a series of clinical syndromes caused by vertebra-basal artery insufficiency such as dizziness, syncope, and blurred vision. Moreover, in the examination of the orthopedic department, it is often necessary to measure the left and right mobility of the neck, but in the existing measurement methods, only a rough judgment can be made on the left and right rotation angle and range of the human neck.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is a schematic diagram of the overall structure of the utility model.

Fig. 2 is the front view of the utility model.

In the figure: a bracket base 1, two positioning frames 2, a protractor 3, a headgear 4, a pointer 5, an opening 101, and a mounting hole 201.

Detailed ways

As shown in Figures 1 to 2, a device for measuring the left and right rotation angles of the head and neck of a human body includes a bracket base 1, two positioning frames 2, a protractor 3, a headgear 4, and a pointer 5, and the positioning frame 2 is adjustable and vertically installed on the bracket. On the base 1, the horizontal ends of the protractor 3 are installed on the positioning frame 2, and the pointer 5 can swing within the scale range of the protractor 3. The headgear 4 is arc-shaped, and the material of the headgear 4 is an elastic material, which can facilitate the subject to wear the headgear to the head position. The protractor 3 has three scale modes, namely: 0-180 degrees marked from left to right; 0-180 degrees marked from right to left; 0-90 degrees marked from center to left and center to right respectively.

In a preferred solution, the two positioning frames 2 are symmetrically provided with mounting holes 201, and the mounting holes 201 are multiple and vertically distributed on the positioning frames 2, and the protractor 3 is installed in the mounting holes 201 by bolts. When the height of the protractor 3 needs to be adjusted, the protractor 3 is installed in the corresponding mounting holes 201 of the two positioning frames 2 to realize the height adjustment of the protractor 3. At the same time, because the mounting holes 201 are symmetrically distributed on the two positioning frames 2, they can be placed in different positions. The height can ensure that the horizontal line of the protractor 3 is parallel to the support base 1, thereby ensuring the measurement accuracy.

In a preferred solution, the support base 1 is provided with an opening 101, and the opening 101 is arc-shaped. During specific measurement, the subject's head is in the opening 101 , which can ensure that the measuring surface of the pointer 5 is close to the protractor 3 .

In a preferred solution, the headgear 4 is arc-shaped. Further, the material of the headgear 4 is elastic material. It is convenient for the person to be measured to put the headgear 4 on the head.

As an alternative, the headgear 4 can be designed as a ring.

The specific method of use is: the subject wears a headgear 4 on his head, and lies on his back at the opening 101 of the bracket base 1; rotates the headgear 4 so that the pointer 5 is located at the initial position of the protractor 3; adjusts the protractor according to the height of the subject's head 3 Position on the positioning frame 1, when adjusted to a suitable height, fix the protractor 3 in the installation hole 201 with corresponding height symmetry, at this time, the horizontal line of the protractor 3 is parallel to the bracket base 1; the measured person rotates to the left, the pointer 5. Rotate with the drive of the head, observe the change of the blood flow rate of the vertebral artery in the human body, record the rotation angle when the vertebral artery is compressed and occluded in the human body, and the measured person rotates to the right, and the pointer 5 is on the head Driven by the rotation, observe the changes in the blood flow rate of the cervical vertebral artery. When the vertebral artery is compressed or occluded, record the rotation angle; or for patients with cervical spine injuries, rotate left or right to measure the cervical spine The maximum angle that the head can be rotated to the left or right to determine the degree of bone injury.

Above-mentioned embodiment is only the preferred technical scheme of the present utility model, and should not be considered as the restriction to the present utility model, and the protection scope of the present utility model should be the technical solution described in the claims, including the technology in the technical solution described in the claims. An equivalent alternative to the feature is the scope of protection.
