The support frame 3 is provided with an upper and lower frame members 2, and the support frame 3 is provided with an upper and lower frame members 3. A control panel 28 is installed on one side of the bed board 1; during operation, in actual application, since different patients are involved in nuclear medicine scanning, if the part in direct contact with the patient's head cannot be replaced and cleaned in time, it is easy to cause the spread of pathogens between patients, increasing the possibility of cross infection. When the patient completes the scan, the winding motor 8 is started through the control panel 28, and the winding motor 8 drives the reel 9 to rotate. The rotation of the reel 9 will pull the used disposable film out of the rotating shaft 4, and the new unused disposable film is output from the discharge port 6 of the reel 3, and passes through the sponge cushion 12 and the memory foam 18, so that the old disposable film is wound on the reel 9, thereby realizing automatic replacement of the disposable film after each use, effectively avoiding cross infection between different patients, and always keeping the bed board 1 clean and hygienic. When the disposable film cylinder needs to be replaced, it can be taken out by rotating the threaded sleeve 5 to open one end of the reel 3.

[0024] See also Figure 1-5 As shown, two groups of two compression springs 10 are symmetrically fixed to one end of the top side of the bed board 1, and the top ends of the compression springs 10 are commonly fixed to a neck pad 11, and a sponge cushion 12 is installed inside the neck pad 11. A rectangular groove 13 with an upward opening is opened inside the top side of one end of the bed board 1, and sleeves 14 are fixedly installed at the four corners of the rectangular groove 13. A buffer spring 15 is fixed inside the sleeve 14, and a movable rod 16 is fixed to the top end of the buffer spring 15. One end of the movable rod 16 extends through the outside of the sleeve 14 and is commonly fixed to a pillow pad 17. A memory foam 18 is installed inside the top side of the pillow pad 17.

[0025] Two slide grooves 19 are symmetrically provided inside the top side of the bed board 1 below the pillow 17, and a slider 20 is slidably installed inside the slide groove 19. A servo motor 21 is installed on one side of the bed board 1, and a bidirectional screw rod 22 is installed on the output end of the servo motor 21. A screw hole is provided inside the slider 20, and one end of the bidirectional screw rod 22 passes through the screw hole and is rotatably installed on one side inner wall of the slide groove 19. A support plate 23 is installed on the top side of the slider 20, and a spring 24 is fixedly connected to one side of the top of the support plate 23. One end of the spring 24 is fixedly connected to a side splint 25, and a mounting seat 26 is installed on the outer wall of the side splint 25. A connecting block 27 is installed on one side of the support plate 23, and the connecting block 27 is mounted on the inside of the mounting seat 26 through a pin shaft. During operation, when scanning the patient's head, there is no device to fix the patient's head, which makes it easy to shake. The movement of the patient's head will affect the scanning results. Therefore, a fixing device is needed. When the patient lies on the bed board 1, the patient's head is placed on the pillow 17, and the neck will contact the neck pad 11. The sponge cushion 12 inside the neck pad 11 has soft characteristics and can deform to a certain extent according to the contour of the patient's neck to provide fitting support. At the same time, the compression spring 10 can expand and contract according to the pressure of the patient's neck, and play a role of buffering and adjustment with the cooperation of the damper, effectively alleviating the neck discomfort caused by long-term fixation. At the same time, the memory sponge 18 inside the pillow 17 will deform according to the shape and pressure of the patient's head, thereby further adapting to the patient's head shape. When pressure is applied to the head, the movable rod 16 will compress the buffer spring 15 in the sleeve 14. The buffer spring 15 provides a certain elastic support with the cooperation of the damper, which reduces the pressure on the head and improves the comfort during the scanning process.

[0026] Finally, the servo motor 21 is started through the control panel 28, and the servo motor 21 drives the bidirectional screw rod 22 to rotate. The rotation of the bidirectional screw rod 22 will cause the slider 20 to slide in the slide groove 19, thereby adjusting the distance between the two support plates 23. The side splints 25 at the top of the support plate 23 will contact both sides of the patient's head, and the spring 1 24 plays an adaptive role. During the scanning process, if the patient's head shakes slightly due to discomfort, the expansion and contraction of the spring 1 24 and the rotation of the side splint 25 around the pin shaft can adapt to this movement to a certain extent without affecting the stability of the fixation, while meeting the needs of patients of different body shapes and improving the flexibility and comfort of the fixation.

[0027] Working principle: When the patient lies on the bed board 1, the patient's head is placed on the pillow 17, and the neck will contact the neck pad 11. The sponge cushion 12 is soft and can deform to a certain extent according to the contour of the patient's neck to provide fitting support. At the same time, the compression spring 10 can expand and contract according to the pressure of the patient's neck, and play a buffering and adjusting role in cooperation with the damper, effectively alleviating the neck discomfort caused by long-term fixation. At the same time, the memory sponge 18 inside the pillow 17 will deform according to the shape and pressure of the patient's head, thereby further adapting to the patient's head shape. When pressure is applied to the head, the movable rod 16 will compress the buffer spring 15 in the sleeve 14. The buffer spring 15 provides a certain elastic support in cooperation with the damper, reducing the pressure on the head and improving the comfort during the scanning process.

[0028] Finally, the servo motor 21 is started through the control panel 28. The servo motor 21 drives the bidirectional screw rod 22 to rotate. The rotation of the bidirectional screw rod 22 causes the slider 20 to slide in the slide groove 19, thereby adjusting the distance between the two support plates 23. The side clamps 25 at the top of the support plates 23 will contact the two sides of the patient's head. The spring 1 24 plays an adaptive role. During the scanning process, if the patient's head shakes slightly due to discomfort, the expansion and contraction of the spring 1 24 and the rotation of the side clamps 25 around the pin can adapt to this movement to a certain extent without affecting the stability of the fixation. At the same time, it meets the needs of patients with different body shapes and improves the flexibility and comfort of the fixation.

[0029] When the patient completes the scan, the winding motor 8 is started through the control panel 28, and the winding motor 8 drives the reel 9 to rotate. The rotation of the reel 9 will pull the used disposable film out of the rotating shaft 4, and the new unused disposable film is output from the discharge port 6 of the reel 3, and passes through the sponge cushion 12 and the memory foam 18, so that the old disposable film is wound on the reel 9, thereby realizing automatic replacement of the disposable film after each use, effectively avoiding cross infection between different patients, and always keeping the bed board 1 clean and hygienic. When the disposable film roll needs to be replaced, it can be taken out by rotating the threaded sleeve 5 to open one end of the reel 3.
