A movable block 111 is fixedly mounted on one end of each T-shaped slider 110. The outer wall of each movable block 111 is rotatably connected to... Each movable ring 104 is connected to a movable strap 105 fixedly installed on the outer wall of the movable ring 104. A first plastic buckle 106 is provided between every two opposite movable straps 105. A positioning knob 112 is threaded into the first positioning screw hole on one side of each movable block 111. A second positioning screw hole corresponding to the first positioning screw hole is provided on the surface of the T-shaped slider 110. A fixing strap 107 is fixedly installed on both sides of the fixed support plate 102. A second plastic buckle 108 is provided between two fixing straps 107. Pull rings 109 are fixedly installed at both ends of both sides of the fixed support plate 102.

[0027] An integrated conveying device for the aforementioned fixing mechanism includes a conveying mechanism 2 connected to the fixing mechanism 1. A limit mechanism 3 is provided at one end of the conveying mechanism 2. The conveying mechanism 2 includes a base 201. A manual hydraulic pump 202 is installed in the middle of the inner wall of the base 201, and hydraulic cylinders 207 are installed on both sides of the inner wall of the base 201. The oil outlet of the manual hydraulic pump 202 is connected to the oil inlet of the two hydraulic cylinders 207 respectively through an oil guide pipe. A pedal 203 is fixedly provided at the drive end of the manual hydraulic pump 202. Support legs 204 are fixedly provided at the four corners of the bottom of the base 201. A support column 205 is fixedly provided at the bottom end of each support leg 204. All are equipped with movable casters 206. A placement frame 208 is fixed between the two hydraulic cylinders 207. An arc-shaped placement groove 209 is opened on the surface of the top of the placement frame 208, and a horizontal bar 210 is fixed on one side of the top of the placement frame 208. The limiting mechanism 3 includes a drive screw 301. The top of the drive screw 301 is rotatably connected to the middle of the bottom of the placement frame 208. A crank 302 is fixed on the bottom of the drive screw 301, and a lifting crossbar 303 is threadedly connected to the outer wall of the drive screw 301.

The outer wall of the U-shaped limiting frame 304 is interlocked with a U-shaped receiving groove opened on one side of the inner wall of the arc-shaped placement groove 209.

[0028] Working principle: During use, the conveying mechanism 2 can move, thereby driving the fixing mechanism 1. When transporting a young patient for a CT scan, each component in the fixing mechanism 1 is made of different types of non-metallic materials. The child is placed on the fixed support plate 102 connected to the reinforced base plate 101, the second plastic buckle 108 is separated, and the child's head is restricted by the fixing strap 107. At the same time, the positioning knob 112 is loosened, and the T-shaped slider 110 connected to the movable block 111 is moved. The T-shaped slider 110 slides in the T-shaped groove 103. After moving to the appropriate position, the positioning knob 112 is tightened, and then the first plastic buckle 106 is loosened. Multiple movable straps 105 restrict multiple parts of the child's body.

[0029] Then, the conveyor 2 can be pushed to move the child. After moving to the CT equipment, step on the pedal 203, which will drive the manual hydraulic pump 202, which will cause the hydraulic cylinder 207 to drive the placement frame 208 to rise and fall. After the fixing mechanism 1 is level with the CT equipment examination bed, the person turns the crank handle 302 to drive the drive screw 301, which will drive the lifting crossbar 303 to move down, which will drive the U-shaped limit frame 304 to move down, thus releasing the restriction on the fixing mechanism 1. The reinforced base plate 101 is embedded with plastic ball bearings 113, which can push the fixing mechanism 1 directly onto the examination bed, so that the child can be examined without having to be transferred again, avoiding secondary injury.

[0030] It should be noted that in the design of the fixation mechanism for PET and CT examinations of young children in this utility model, in order to avoid and reduce interference with the radiographic images, all components involved in radiographic scanning are made of low-density metals or high-strength plastics or composite materials, such as aluminum alloys, plastics or carbon fiber composite materials.
