When the cushion block 45 moves downward, the two No. 1 racks 414 are pushed away from each other through the two connecting rods 413, and the two No. 1 racks 414 respectively drive the two No. 2 racks 416 to move towards each other through the two No. 1 gears 415, and the two No. 2 racks 416 drive the two slides 42 to move towards each other, and the two slides 42 respectively drive the two head support plates 44 and the two face support plates 43 to move towards the patient's head, so that the two face support plates 43 clamp the patient's face, and the two head support plates 44 clamp the patient's head, so as to achieve the patient's To fix the head, the two face support plates 43 can achieve a certain position adjustment through the elastic force of the springs, and the two head support plates 44 can achieve a certain position adjustment through the elastic force of the spring sheets, so that the two face support plates 43 and the two head support plates 44 can flexibly clamp the patient's head, thereby improving the patient's comfort. The multiple springs at the bottom of the cushion block 45 have a certain elasticity, which improves the comfort of the back of the patient's head, and after the patient stands up, the cushion block 45 can rebound. After the cushion block 45 rebounds, the two slide seats 42 are reset accordingly; when the inspection work is completed, the motor 411 is started, and the motor 411 drives the ball screw 410 to rotate. When the ball screw 410 rotates, the ball block 49 is driven to move to the bottom of the bed board 3 through the cooperation of the threaded groove and the ball. When the sliding pad 41 is moved to the left, the ball block 49 drives the force transmission rod 48 to move to the left, the force transmission rod 48 drives the sliding rod 47 to move to the left, and the sliding rod 47 drives the sliding pad 41 to slide to the left on the two sliding rails 417 through the slip ring 46. Since the sliding rail 417 is bent and a part of the sliding rail 417 is located in the storage box 412, the sliding pad 41 slides along the two sliding rails 417 to the inside of the storage box 412, thereby achieving the effect of automatically storing the sliding pad 41. When checking again, the motor 411 is started in the reverse direction, and the ball block 49 drives the sliding rod 47 to move to the right through the force transmission rod 48, and the sliding rod 47 drives the sliding pad 41 to return to the initial position to the right through the slip ring 46; in the process of the sliding rod 47 moving to the left, it will contact the push block 422 and push it to the left, and the push block When the slider 422 moves to the left, the slider 420 is pushed upward by the push rod 421, and the slider 420 pushes the cover plate 418 to the right through the push rod 419. When the slide pad 41, the two slide seats 42, the two face support plates 43 and the two head support plates 44 are all located in the storage box 412, the cover plate 418 completely covers the storage box 412, playing a certain protective role to prevent dust and foreign matter from falling into the storage box 412. When the slide bar 47 moves to the right, the slide bar 47 gradually breaks away from the contact with the push block 422, and the push block 422 is reset to the right by the elastic force of the spring. The push block 422 drives the slider 420 to move downward through the push rod 421, and the slider 420 drives the cover plate 418 to move to the left through the push rod 419, so that the cover plate 418 is opened.Through the setting of the head support device 4, after the patient lies on the bed board 3, the two face support boards 43 and the two head support boards 44 can automatically approach the patient's head, flexibly clamp the patient's head, and maintain the stability of the patient's head during the examination process; through the setting of the storage box 412 and the two slide rails 417, the slide pad 41, the two slide seats 42, the two face support boards 43 and the two head support boards 44 can be automatically stored in the storage box 412 when not in use, which is convenient for the staff to clean the bed board 3, and also plays a certain protective role, extending the service life of the head support device 4; through the setting of the cover plate 418, the head support device 4 can be automatically closed after being stored, and the cover plate 418 can be automatically opened when it is needed to prevent dust and debris from falling into the storage box 412, further improving the protective effect. ;

[0043] The disposable bed sheet 54 is arranged in a roll. When in use, the disposable bed sheet 54 is put on the No. 1 shaft 52, and the disposable bed sheet 54 is pulled to make the disposable bed sheet 54 be changed on the bed board 3. After the end of the disposable bed sheet 54 is guided along the tail of the bed frame 2 and the guide shaft 513, it is fixed on the No. 2 shaft 53 through the clip on the No. 2 shaft 53. After the inspection is completed, when the force transmission rod 48 moves to the left, the force transmission rod 48 drives the two No. 3 racks 57 to move to the left through the connecting rod 56, and the No. 2 gear 58 can drive the No. 2 shaft 53 to rotate unidirectionally through the cooperation of the ratchet pawl. In the process of the two No. 3 racks 57 moving to the left, the two No. 2 gears 58 drive the No. 2 shaft 53 to rotate, so that the No. 2 shaft 53 passes through the No. 2 gears 58. By rotating and rolling up the disposable bed sheet 54, the disposable bed sheet 54 that has been in contact with the patient before is rolled up onto the No. 2 shaft 53, and the new disposable bed sheet 54 is rolled out from the No. 1 shaft 52 and placed on the bed board 3, thereby achieving the effect of automatically replacing the disposable bed sheet 54. When the force transmission rod 48 moves to the right, the two No. 3 racks 57 move to the right accordingly. At this time, the two No. 2 gears 58 will not drive the No. 2 shaft 53 to rotate when rotating, so as to prevent the disposable bed sheet 54 from being separated from the No. 2 shaft 53. The two baffles 55 on the No. 2 shaft 53 can resist the two sides of the disposable bed sheet 54, so as to maintain the neatness of the disposable bed sheet 54 when rolling up; the multiple pressure heads 512 on the two sliding frames 510 press the disposable bed sheet The two sides of 54 maintain the fit between the disposable bed sheet 54 and the bed board 3. When the two No. 3 racks 57 move to the left, the two inclined rods 59 move to the left. When the two inclined rods 59 move to the left, the two arc blocks 511 are respectively lifted upward by the inclined surface. The two arc blocks 511 drive the two sliding racks 510 to move upward. The multiple pressure heads 512 on the two sliding racks 510 are separated from the contact with the disposable bed sheet 54 to avoid affecting the rolling process of the disposable bed sheet 54. After the two inclined rods 59 follow the two No. 3 racks 57 to reset to the right, the two sliding racks 510 fall down by their own gravity, and the multiple pressure heads 512 are pressed on the disposable bed sheet 54 again. The arrangement enables, after the examination is completed, the first shaft 52 cooperates with the second shaft 53 to roll up the disposable bed sheet 54 that was previously in contact with the patient into the temporary storage box 51, and the new disposable bed sheet 54 is automatically drawn out, so as to maintain the cleanliness of the disposable bed sheet 54 on the bed board 3, thereby reducing the work of medical staff in changing the bed sheet; by the arrangement of the multiple pressure heads 512, before the patient lies on the disposable bed sheet 54, the multiple pressure heads 512 can press down on both sides of the disposable bed sheet 54, so as to prevent part of the disposable bed sheet 54 from being out of contact with the bed board 3 due to the movement of the patient's body; when the disposable bed sheet 54 is rolled up, the multiple pressure heads 512 automatically rise up, so as to avoid affecting the rolling process of the disposable bed sheet 54.

[0044] The water tank 61 is filled with disinfectant water. When the two baffles 55 rotate, the two baffles 55 drive the multiple protrusions 64 to rotate. When the multiple protrusions 64 rotate, they contact and squeeze the airbag 63 in turn. After the airbag 63 is squeezed, the air is injected into the water tank 61 through the air pipe 62. The water tank 61 uses the positive pressure principle to transport the disinfectant water inside it to the connecting seat 66 through the rotating tube 65. The two atomizing nozzles 67 on the connecting seat 66 spray the disinfectant water. The two atomizing nozzles 67 are located under the disposable bed sheet 54. The two atomizing nozzles 67 spray disinfectant on the disposable bed sheet 54, so that the disposable bed sheet 54 is disinfected before being rolled up to prevent bacteria from growing in the temporary storage box 51. When the No. 3 rack 57 with the connecting block 610 moves to the left, the connecting block 610 pulls one end of the pull rope 68 to the left, so that the pull rope 68 is pulled to the left along the two guide rods 69. When the pull rope 68 is pulled, the rotating tube 65 is driven to rotate. The rotating tube 65 is connected to the connecting block 610. The connection seat 66 drives the two atomizing nozzles 67 to rotate. The two atomizing nozzles 67 can expand the spraying area through rotation, so that the spraying effect of the disinfectant water is more uniform. After the connecting block 610 moves to the right, the rotating tube 65 rotates and resets due to the elastic force of the coil spring 611. During the rotation and reset process of the rotating tube 65, the pull rope 68 is reeled in to reset the pull rope 68. Through the setting of the disinfection device 6, the two atomizing nozzles 67 can spray the disinfectant water before the disposable bed sheet 54 is reeled in to the second shaft 53. The toxic water is sprayed on the disposable bed sheet 54 to disinfect the disposable bed sheet 54, thereby preventing bacteria on the disposable bed sheet 54 from growing in the temporary storage box 51 and causing safety risks; through the setting of the pull rope 68, the pull rope 68 can drive the rotating tube 65 to rotate when the two atomizing nozzles 67 spray the disinfectant water, and the rotating tube 65 drives the two atomizing nozzles 67 to rotate through the connecting seat 66, thereby expanding the spraying range of the two atomizing nozzles 67, improving the spraying uniformity, and promoting the disinfection effect.
