Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of CT examination beds, and more particularly to a patient lateral support structure for CT medical examinations. Background Art
[0002] CT, or computerized tomography, uses precisely collimated X-ray beams, gamma rays, ultrasound waves, and highly sensitive detectors to perform cross-sectional scans around a certain part of the human body. It has the characteristics of fast scanning time and clear images, and can be used to detect a variety of diseases.
[0003] Chinese patent CN213607649U (application number: 202022309145.3) discloses a "lateral support adjustment device for bedridden patient care". In its embodiment, the device is placed on the patient's back, and the handle is turned to drive the transmission shaft to rotate through the engagement of the active bevel gear and the driven bevel gear. The screw is driven to rotate under the transmission of the worm and the worm wheel. After the screw rotates, the sleeve is driven to move, and then the support plate is pushed up under the hinged action of the first hinge block, the hinge rod and the second hinge block, thereby assisting the patient to turn over. At the same time, after the handle stops rotating, the support plate can form an automatic fixing effect to support the patient's back. The purpose of the support is, firstly, to reduce the difficulty of nursing for medical staff, and secondly, to alleviate the aggravation of the patient's condition. At the same time, the support angle can be adjusted at will, but in actual use, manual operation is required, which has high labor intensity. In addition, the patient's body is supported sideways by only flipping the support plate, and there is a lack of a limiting structure for the other side of the patient. It is easy for the patient to slide off the support plate when lying sideways, causing secondary injury to the patient, and the patient's side support cannot be completed. At the same time, the overall thickness of the structure is relatively high. When the device is installed on the bed as a whole, the surface of the examination bed will be uneven, resulting in poor comfort for the patient when lying down, which cannot meet the needs of actual use. Summary of the Invention
[0004] In view of the deficiencies in the prior art, the present invention aims to provide a patient side support structure for CT medical examinations.
[0005] To achieve the above object, the present invention provides the following technical solutions:

The overall operation does not require manual operation and has a high degree of automation. At the same time, the structure is arranged as a whole on the CT examination bed with a smooth and comfortable surface. When the patient is supported on the device as a whole, the compression spring 11 is compressed as a whole under the action of the bottom support plate 1002 and the mounting ear 106 to support the device as a whole, thereby improving the comfort of the patient when lying down for examination and meeting the needs of actual use.
