[0032] Specifically, when the CT bed 1 needs to be used, the dust-free cloth 255 is pulled and one end of the dust-free cloth 255 is inserted into the long groove 211. Then the long plate 213 is moved to allow the long plate 213 to clamp the dust-free cloth 255. At this time, the clamping frame 214 will be on the same vertical line as the rectangular frame 212. At this time, the clamping bolt 215 is inserted into the rectangular frame 212 and the clamping frame 214 to fix the long plate 213. Then the patient can lie on the CT bed 1 and put his head on the headrest 27. At this time, there is a layer of dust-free cloth 255 between the headrest 27 and the patient's head. At this time, impurities generated by the patient's head will fall on the surface of the dust-free cloth 255, and the softness of the headrest 27 can improve the patient's comfort. After the patient lies flat, the doctor will fix the fixing rod After one end of 2828 is pulled out of the fixing hole 216, the turntable 2827 is rotated. As the turntable 2827 rotates, the cone block 2822 on the surface of the rotating rod 2821 will reciprocate and squeeze the pressure plate 2835, allowing the piston 2836 to squeeze the gas inside the through hole 2832 into the air box 2831, and the gas inside the air box 2831 will squeeze into the air bag 2838, so that the air bag 2838 is inflated. Since a plastic one-way valve is provided at one end of the L tube 2837 connected to the air bag 2838, when the carbon fiber spring 2814 is reset, the air inlet pipe 2834 will draw external gas into the through hole 2832, and then wait for the squeezing of the piston 2836. As the air bag 2838 is gradually inflated, the air bag 2838 will bring the sponge pad 2839 to the patient's head. To fix it, while the rotating rod 2821 rotates, the carbon fiber gear 2823 will lead the top plate 2824 to rise, allowing the top plate 2824 to push up the silicone pad 29, thereby supporting the patient's neck. Since the silicone pad 29 itself is relatively soft, it can further improve the patient's comfort. Then, one end of the fixing rod 2828 is reinserted into the fixing hole 216 to fix the height of the silicone pad 29. When the silicone pad 29 is against the patient's neck, the airbag 2838 also fixes the patient's head with the sponge pad 2839. At this time, a CT scan can be performed. After the CT scan is completed, it is only necessary to take out the air plug 3, and then take out one end of the fixing rod 2828 from the fixing hole 216. The silicone pad 29 will be The weight is lowered, and the fixed rod 2828 of the air plug 3 is pulled out to discharge all the gas. When the patient stands up, the doctor slides the dial plate 2623 to let the carbon fiber blade 2624 cut the dust-free cloth 255, takes away the used dust-free cloth 255, and then pulls the dust-free cloth 255 again. As the dust-free cloth 255 is pulled, the rod groove 264 will carry the sponge roller 266 to rotate while reciprocating along the thread of the reciprocating screw rod 267 itself, and the stickiness of the dust-sticking roller 2661 itself can stick to the impurities that may exist in the dust-free cloth 255.
