[0025] In use, the annular pressing plate 308 is fixedly connected with the outer wall of the annular supporting plate 305. In use, the person to be scanned lies on the bed plate 202 of the transfer bed 2. The connecting tube 4 on the hand is wound one or two circles on the annular supporting plate 305. Then the connecting tube 4 is placed between the two arc-shaped plates 503 close to the person to be examined. The horizontal groove 502 is forced to be opened upward. The connecting tube 4 is clamped into the sleeve 501. Since the diameter of the connecting tube 4 is greater than that of the sleeve 501, the connecting tube 4 clamped into the sleeve 501 is in interference fit. Therefore, when the transfer bed 2 drives the bed plate 202 to move, the connecting tube 4 is pulled, avoiding the connecting tube 4 from being stuck and avoiding the indwelling needle from being accidentally pulled out when the connecting tube 4 is dragged.

[0026] Embodiment two: refer to Figures 1-4 A CT high-pressure injector connecting tube auxiliary moving device, which is different from embodiment one. The inner side of the annular pressing plate 308 is slidably connected with the outer wall of the annular supporting plate 305. The outer wall top end and bottom end of the annular supporting plate 305 are respectively fixedly installed with the annular top plate 307 and the annular bottom plate 306. The top end of the annular pressing plate 308 is installed with the thrust spring 309. The top end of the thrust spring 309 is fixedly connected with the top end of the annular top plate 307.
