[0047] In the above embodiment, if Figure 1 As shown, the main body of the pediatric nasopharyngeal lateral X-ray auxiliary positioning device of the utility model is composed of a frame 100 and a positioning bracket 200, wherein the frame 100 is used to support the positioning bracket 200. Since the X-ray shooting has a certain range, in order to reduce the image produced by the auxiliary positioning device on the shooting, in this embodiment, a bending portion 121 is also provided at the upper end of the frame 100, and the bending portion 121 is bent in the horizontal direction. The positioning bracket 200 is fixedly arranged on the end of the bending portion, so that the frame 100 is away from the irradiation range of the X-ray. At the same time, the positioning bracket 200 supports the facial area of ​​the child and will not affect the shooting range of the child's pharynx. Therefore, it can assist the child's head positioning without affecting the shooting effect.

[0048] The positioning bracket 200 specifically includes a first baffle plate 210 which is horizontally arranged, and a positioning groove 211 is arranged on the first baffle plate 210.

The elastic pad 212 can be replaced in actual use to meet the hygiene requirements of different patients and prevent the spread of skin diseases and infectious diseases.

[0053] In another embodiment of the present invention, Figure 1 and Figure 2 As shown, first slide grooves 213 are symmetrically arranged at both ends of one side of the first baffle plate 210, and correspondingly, first slide grooves 213 are symmetrically arranged at both ends of one side of the second baffle plate 220, and the first slide grooves 213 and the second slide grooves 221 at both ends correspond to each other in the vertical projection direction;

[0054] like Figure 3 As shown, a first sliding tenon 231 and a second sliding tenon 232 are also provided on the side of the first splint 230, wherein the first sliding tenon 231 is embedded in the first sliding groove 213 and can slide freely along the direction in which the first sliding groove 213 is set, and the second sliding tenon 232 is embedded in the second sliding groove 221 and can slide freely along the direction in which the second sliding groove 221 is set. The first sliding groove 213 and the second sliding groove 221 are arranged in parallel, so that the first splint 230 can slide along the same side of the first baffle plate 210 and the second baffle plate 220 to adjust the relative position between the first splint 230 and the positioning groove 211. Correspondingly, the second splint 240 has the same structure and the same method of use as the first splint 230, which will not be repeated here. By adjusting the position of the first splint 230 and the second splint 240, the two sides of the head of the child with the lower jaw placed on the positioning groove 211 can be clamped, thereby achieving the effect of limiting the head of the child.

[0055] In actual settings, the first splint 230 and the second splint 240 should be made of materials with low X-ray absorption and uniform texture, and the materials used should be non-metallic, such as glass, synthetic materials, etc. At the same time, in order to facilitate observation of the condition of the child, the first splint 230 and the second splint 240 should be made of transparent materials to facilitate medical staff to distinguish whether the child is feeling unwell.

[0056] Furthermore, in order to prevent the head of the child from rotating during the shooting process, causing the first clamping plate 230 and the second clamping plate 240 to move and lose their limiting function, in this embodiment, Figure 3 , Figure 1 and Figure 4 As shown, a plurality of card slots 222 are respectively provided at positions corresponding to the first clamping plate 230 and the second clamping plate 240 on the above-mentioned second baffle plate 220.
