Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a head support device for CT examination. Background Technology

[0002] A head support device for CT scans is a medical device specifically designed for CT imaging examinations. It typically includes a base plate, fixation components (such as fixation slots, toothed plates, gears, etc.), and support components (such as support blocks or support airbags) to fix and support the patient's head, ensuring stability and accuracy during the examination.

[0003] A search revealed a Chinese patent for a head support device for CT examinations (authorization announcement number CN218852722U), which also falls under the field of medical device technology. This patent includes a "fixation component, whose fixing parts are respectively connected to the bottom of its telescopic component and the CT bed; the top of the telescopic component supports the head support component; the head support component includes a main board, a left side plate, a right side plate, and bolts; the bolt on the left side of the main board passes through one of the half-sleeves on that side and the half-sleeves on the left side plate and is threaded to the other." While this patented technology can adjust the angle of the head support component to support the patient's head...

[0004] However, in practical applications, this patented technology is inconvenient for fixing the patient's head, and the image may become blurred due to head movement during the scan, thus affecting the doctor's diagnosis. To address these issues, the inventors have proposed a head support device for CT examinations. Utility Model Content

[0005] In order to solve the problem of head support and fixation during CT examinations, the purpose of this utility model is to provide a head support device for CT examinations.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a head support device for CT examination, including a diagnostic bed, a rotating plate rotatably connected to one side of the diagnostic bed, a headrest frame fixedly connected to the end of the rotating plate away from the diagnostic bed, an L-shaped plate fixedly connected to one side of the diagnostic bed and below the rotating plate, an angle adjustment component provided between the L-shaped plate and the rotating plate, a coarse adjustment component provided inside the headrest frame, fine adjustment components provided on both sides of the headrest frame, and two symmetrically distributed reinforcing ribs fixedly connected to the bottom side of the L-shaped plate and the diagnostic bed.

[0007] Preferably, the angle adjustment assembly includes a lead screw, which is rotatably connected between the L-shaped plate and the diagnostic bed. A slider is threadedly connected to the outer side of the lead screw, and the slider is slidably engaged with the top of the L-shaped plate. A connecting rod is rotatably connected to the top of the slider, and the end of the connecting rod away from the slider is rotatably connected to a rotating plate. One end of the lead screw extends to one side of the L-shaped plate and is fixedly connected to a knob.

[0008] Preferably, the coarse adjustment component includes symmetrically distributed slide rails, which are fixedly connected to the top of the inner wall of the headrest frame. Slide rods are slidably engaged on the outer sides of each slide rail, with two slide rods centrally symmetrically distributed. Racks are fixedly connected to the sides of the slide rods that are close to each other. A gear is rotatably connected to the middle of the inner wall of the headrest frame, and both racks mesh with the gear. The coarse adjustment component also includes a worm gear, which is fixedly connected to the outer side of the gear's rotating shaft. A worm is rotatably connected to the inner side of the headrest frame near the worm gear, and the worm meshes with the worm gear. One end of the worm's rotating shaft extends to one side of the headrest frame and is fixedly connected to a knob.

[0009] Preferably, the fine-tuning component includes a mounting base, and the ends of the sliding rods that are far apart from each other extend movably to the outside of the headrest frame and are fixedly connected to the mounting base. The top of the mounting base is threaded with a threaded rod, and the ends of the two threaded rods that are close to each other are rotatably connected to a clamping plate. The ends of the threaded rods that are far away from the clamping plate are fixedly connected to a knob.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Rotating knob two drives the worm gear to rotate, which in turn meshes with the worm wheel, simultaneously driving the gear and worm wheel to rotate. The gear meshes with two racks, simultaneously moving the two sliding rods to either move away from or closer to each other, thus coarsely adjusting the distance between the clamps. Rotating knob three drives the threaded rod to rotate, simultaneously pushing the clamps to move laterally, thus finely adjusting the distance between the clamps. This achieves clamping and fixing of the patient's head, making the operation convenient and quick, and further improving the efficiency of CT head examinations. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a head support device for CT examination, including a diagnostic bed 1, a rotating plate 2 rotatably connected to one side of the diagnostic bed 1, a headrest frame 3 fixedly connected to the end of the rotating plate 2 away from the diagnostic bed 1, an L-shaped plate 4 fixedly connected to one side of the diagnostic bed 1 and below the rotating plate 2, an angle adjustment component 5 provided between the L-shaped plate 4 and the rotating plate 2, a coarse adjustment component 6 provided inside the headrest frame 3, and fine adjustment components 7 provided on both sides of the headrest frame 3.

[0020] The angle adjustment assembly 5 includes a lead screw 51, which is rotatably connected between the L-shaped plate 4 and the diagnostic bed 1. A slider 52 is threadedly connected to the outer side of the lead screw 51. The slider 52 is slidably engaged with the top of the L-shaped plate 4. A connecting rod 53 is rotatably connected to the top of the slider 52. The end of the connecting rod 53 away from the slider 52 is rotatably connected to the rotating plate 2. One end of the lead screw 51 extends to one side of the L-shaped plate 4 and is fixedly connected to a knob 54.

[0021] By adopting the above technical solution, by rotating the knob 54, the lead screw 51 is rotated, and the slider 52 is slid laterally along the top of the L-shaped plate 4. Utilizing the connecting rod 53, the rotating plate 2 is rotated vertically, thereby adjusting the vertical angle of the headrest frame 3 to meet the needs of patients with cervical hyperflexion or hyperextension.

[0022] The coarse adjustment component 6 includes symmetrically distributed slide rails 61, which are fixedly connected to the top of the inner wall of the headrest frame 3. Slide rods 62 are slidably engaged on the outer side of each slide rail 61. The two slide rods 62 are centrally symmetrically distributed. A rack 63 is fixedly connected to the side of each slide rod 62 that is close to each other. A gear 64 is rotatably connected to the middle of the inner wall of the headrest frame 3. Both racks 63 are meshed with the gear 64.

[0023] By adopting the above technical solution, when the gear 64 rotates, it meshes with the two racks 63, and at the same time drives the two slide rods 62 to move to the side that is further away from or closer to each other, thereby realizing the adjustment of the distance of the fine-tuning component 7.

[0024] The coarse adjustment assembly 6 also includes a worm gear 65, which is fixedly connected to the outside of the rotating shaft of the gear 64. A worm 66 is rotatably connected to the inside of the headrest frame 3 near the worm gear 65. The worm 66 and the worm gear 65 are meshed together. One end of the rotating shaft of the worm 66 extends to one side of the headrest frame 3 and is fixedly connected to a knob 67.

[0025] By adopting the above technical solution, the worm 66 is driven to rotate by rotating the knob 67. The worm 66 and the worm wheel 65 are meshed and connected, which simultaneously drives the gear 64 and the worm wheel 65 to rotate, thereby realizing the drive of the equipment. Furthermore, the reverse self-locking property between the worm wheel 65 and the worm 66 is used to further improve the stability of the structure.

[0026] The fine-tuning component 7 includes a mounting base 71, and two sliding rods 62 whose ends are far apart extend to the outside of the headrest frame 3 and are fixedly connected to the mounting base 71. The top of the mounting base 71 is threaded with threaded rods 72. The ends of the two threaded rods 72 that are close to each other are rotatably connected to clamps 73. The ends of the threaded rods 72 that are far away from the clamps 73 are fixedly connected to knobs 74.

[0027] By adopting the above technical solution, the screw rod 72 is rotated by turning the knob 74, which in turn pushes the clamp 73 to move laterally, and the distance between the clamps 73 is finely adjusted to achieve clamping and fixing of the patient's head.

[0028] Two symmetrically distributed reinforcing ribs 8 are fixedly connected between the bottom side of the L-shaped plate 4 and the diagnostic bed 1.

[0029] By adopting the above technical solution and setting the reinforcing ribs 8, the stability of the connection between the L-shaped plate 4 and the diagnostic bed 1 can be enhanced.

[0030] Working principle: During CT scans, when supporting and fixing the patient's head, rotating knob 54 rotates the lead screw 51, which in turn moves the slider 52 laterally along the top of the L-shaped plate 4. The connecting rod 53 also causes the rotating plate 2 to rotate vertically, adjusting the vertical angle of the headrest frame 3 to accommodate patients with cervical hyperflexion or hyperextension. Rotating knob 67 rotates the worm gear 66, which meshes with the worm wheel 65, simultaneously rotating the gear 64 and the worm wheel 65. The gear 64 meshes with two racks 63, moving the two sliders 62 towards one side or away from each other, thus roughly adjusting the distance between the clamps 73. Rotating knob 74 rotates the threaded rod 72, simultaneously pushing the clamps 73 laterally, fine-tuning the distance between them, thus achieving the clamping and fixing of the patient's head.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
