Embodiment Construction

[0019] Such as Figure 1~2 Among them, a device for measuring the left and right rotation angles of the head and neck of a human body, including a bracket base 1, two positioning frames 2, a protractor 3, a headgear 4 and a pointer 5, the positioning frame 2 is adjustable and vertically installed on the bracket base 1, and the protractor 3 The horizontal ends are installed on the positioning frame 2, and the pointer 5 can swing within the scale range of the protractor 3. Both ends of the protractor 3 are provided with chute 301, the chute 301 can slide on the positioning frame 2, and the chute 301 and the positioning frame 2 are fixed by tightening bolts. 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 4 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 cent...

Abstract

The invention provides a device for measuring a left-right rotation angel of a head and neck part of a human body. The device comprises a support base, two positioning racks, a protractor, a head sleeve and a pointer, wherein the positioning racks are adjustably and vertically mounted on the support base; two horizontal ends of the protractor are mounted on the positioning racks; and the pointer can swing in a scale range of the protractor. By the device, the left-right rotation angle of the neck part of the human body when the human body is in a supine position can be measured accurately. The device is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of medical testing instruments, in particular to a device for measuring the left and right rotation angles of the head and neck of a human body. Background technique [0002] Due to factors such as diseases, congenital abnormalities of bone development, and abnormal course of cervical vertebral arteries, some people will experience compression or even occlusion of the vertebral arteries when the head and neck rotate to the left or right. , The right rotation angle 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 human head and neck 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 exact angle when compression and occlusion occur, so as to prevent excessive left and right movement angles of the human h...
