Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of CT examination, in particular to a CT examination pillow. Background Art
[0002] CT examination is a medical diagnostic method that uses X-rays and computer technology to create detailed images of the internal structure of the body. During the CT examination process, especially the examination of the head, the patient needs to raise his hands over his head and lean on the headrest, and then adjust the height of the headrest according to different patient needs. However, the existing head and hand supports are fixed, and only the pads are hard-stuffed under the headrest, which is not only time-consuming and laborious, but also poorly fit with the human body, and cannot be quickly adjusted to the height of the headrest suitable for the patient, and is not suitable for patients who are old, weak, and have difficulty raising their limbs. In addition, there is no convergence and fixation effect on the patient's hands. It is easy for the patient's hands to slip off the headrest during the examination, and the patient's limbs move during the examination due to uncomfortable posture, resulting in motion artifacts during the examination, thereby reducing the image quality, requiring repeated examinations, and low examination efficiency, time-consuming and laborious. Some patients also need to raise their chest or waist to increase the height during the examination. At present, they all use pillows under the waist or back, but the thickness of the pillows is uneven, and it is not convenient to adjust to the appropriate height according to needs.
[0003] In view of the above problems, a CT examination pillow is needed. Utility Model Content
[0004] The purpose of the utility model is to provide a CT examination pillow.

[0013] Before use, the patient's head is placed in the headrest groove, and then the staff rotates the rotating disk by hand, or directly rotates the rotating rod by hand to drive the rotating disk to rotate, the rotating disk drives the rotating shaft to rotate, and then the gear on the rotating shaft drives the lifting plate to move up and down, thereby driving the lifting rod to move up and down, and the lifting rod drives the entire headrest to move up and down, which can conveniently adjust the patient's head to a suitable height according to the patient's condition, and then insert the limit clamp into the through hole on the rotating disk, and then insert it into the limit hole to fix the height;
[0014] The patient's hands are raised above the head and placed on the headrest, and the hand stops are used to block the patient's hands to prevent them from sliding off the headrest during the examination, avoiding examination artifacts, improving examination efficiency, and saving time. The hand stops are made of silicone and can change the curvature appropriately according to the patient's hands, thereby improving the comfort of the patient when raising his hands above the head.
[0015] When some patients need to raise their chests, they can directly insert the connecting rod into the connecting hole, and then use the air pump to connect the flushing and deflation holes to inflate the internal airbag, so as to facilitate the patient's chest or waist to be raised or lowered to a suitable height. When not needed, the connecting rod can be directly pulled out of the connecting hole. The operation is simple and convenient.
