Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an automatic centering and positioning mechanism for a CT examination bed. Background Technology
[0002] An automatic centering and positioning mechanism is a device that can automatically adjust workpieces and equipment to a preset center position through a mechanical structure. It typically uses symmetrical guide components and elastic reset structures, along with cylinders and motor power sources, to generate centripetal force during workpiece placement or movement, gradually eliminating positional deviations and ultimately achieving high-precision center alignment. In industrial production, automatic centering and positioning mechanisms are widely used in welding, assembly, and inspection processes. Their adaptive adjustment capabilities can meet the positioning requirements of different specifications.
[0003] The automatic centering and positioning mechanism of a CT examination bed is a core component designed for precise control of patient position. For patients who need multiple scans, it can reproduce the same centering position through memory function, ensuring the comparability of images at different times. For children and the elderly who have difficulty maintaining their position independently, its gentle adjustment force and rapid response capability can reduce the difficulty of patient cooperation. However, the traditional structure uses a sliding rail structure, which lacks stability and accuracy, leading to errors in detection and wasting manpower. Utility Model Content

[0041] When one patient finishes using the device and the next patient needs to use it, the single-head motor 206 is activated, which drives the rotating shaft 209 to rotate via the moving wheel 6. The rotating shaft 209 then drives the core 205 to rotate, wrapping the sheet 204 around the outer wall of the core 205.

If the core 205 is fully wrapped, the core 205 on the outer wall of the rotating shaft 209 can be removed and replaced with a new core 205, achieving the effect of quickly changing the sheet 204 and avoiding the risk of infection.
