CT special pillow device capable of adjusting cervical curvature

Abstract

The invention relates to the technical field of medical instruments, and discloses a CT special pillow device capable of adjusting cervical curvature. The CT special pillow device comprises a bed bodyand a base, wherein the top of the bed body is movably connected with a bottom plate; the outer part of the bottom plate is movably connected with a fixing rod; the outer part of the bottom plate ismovably connected with a first shell; the inner part of the first shell is movably connected with a connecting rod; under the interaction of the bed body, the bottom plate, the fixing rod, the first shell, the connecting rod, a first spring, a copper rod, a second shell, a partition plate, an N pole and an S pole, the position of the device can be adjusted according to the height of a user, so that the use of different people can be met, and the device is detachable; and when the user uses the device, the external pressure can be sensed by utilizing an electromagnetic induction structure, so that the lifting of a subsequent lifting device is adjusted, the effect of changing the cervical curvature of the user can be achieved, the clearness of a scanned image is facilitated, and the device is more suitable for being used in actual conditions.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a CT special pillow device capable of adjusting the curvature of the cervical vertebra. Background technique [0002] CT scans a certain thickness of a certain part of the human body with an X-ray beam. The detector receives the X-rays that pass through the layer and converts it into visible light. The photoelectric conversion is converted into an electrical signal, and then converted by an analog / digital converter. It is a number, which is input to the computer for processing. The image formation process is like dividing the selected layer into several rectangular parallelepipeds with the same volume, called voxels. [0003] The working procedure of CT is as follows: According to the difference in absorption and transmittance of X-rays by different tissues of the human body, it uses highly sensitive instruments to measure the human body, and then inputs the data obtained by ...

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides a special pillow device for CT that can adjust the curvature of the cervical spine, which has the advantages of adjusting the curvature of the cervical spine and better comfort, and solves the problem of image scanning in the cervical-thoracic junction area of ​​the human body. The occlusion of the shoulder distorts the image of the cervical-thoracic junction area, which leads to deviations in the diagnosis of spinal diseases in the cervical-thoracic junction area, which seriously affects the diagnosis of patients. This will prevent patients from receiving more accurate treatment, resulting in The disease was not discovered in time. Although the pillow is placed under the patient's body, there is no way to adjust the curvature of the patient's cervical spine. This will still affect the distortion of the image scan, which will still affect the follow-up treatment, and the hard needle It can also make patients feel uncomfortable
