Description

Technical Field

[0001] The utility model relates to the technical field of head supports for CT machines, and more specifically, to a head support device for CT machines. Background Art

[0002] In the existing technology, the head support device for CT machines is an important component of medical imaging equipment. It is used to support the patient's head during CT scanning to ensure the clarity and accuracy of the image. However, the existing head support device for CT machines faces the problem of being unable to conveniently adjust and fix the headrest angle when in use, which seriously affects the convenience of the equipment and the comfort of the patient.

[0003] First, the existing head support device for CT machines is inconvenient when adjusting the angle of the headrest. Since different patients have different requirements for the angle of head support, the support device needs to be able to adjust according to the specific needs of the patient. However, the design of existing equipment in adjusting the angle of the headrest may have defects. These problems may cause medical staff to spend more time and energy when adjusting the angle of the headrest, increase the complexity of the operation, and reduce the convenience of the equipment.

[0004] Secondly, existing head support devices for CT machines also have problems when fixing the angle of the headrest. During the CT scan, it is necessary to ensure that the patient's head is stable and fixed to avoid image blur or artifacts caused by head movement. However, the design of existing equipment in fixing the angle of the headrest may not be perfect, such as insufficient reliability of the fixing mechanism, limited adjustment range of the fixing mechanism, or poor fixing effect. These problems may cause the headrest angle to shift or change during the scan, affecting the quality and accuracy of the image. Utility Model Content

[0030] See also Figure 1-5 A head support device for a CT machine includes a fixing rod 1, which is installed on an external device. A fixing mechanism is arranged on the fixing rod 1. The fixing mechanism includes an insertion rod 2, a fixing sleeve 3, an external sleeve 4, a rotating mechanism, a hexagonal sleeve 5, a pressing plate 6, a clamping mechanism, a push plate 7, a rotating sleeve 8 and a compression spring 9. The rotating mechanism is cooperatively connected to the fixing rod 1 and the external sleeve 4. A hexagonal groove 10 is provided on the external sleeve 4. The hexagonal sleeve 5 is installed in the hexagonal groove 10. The fixing sleeve 3 is installed on the hexagonal sleeve 5. The clamping mechanism is cooperatively connected to the pressing plate 6 and the push plate 7. The pressing plate 6 abuts against the side wall of the insertion rod 2. A lateral groove 11 is provided on the side wall of the fixing sleeve 3. The push plate 7 is slidably connected to the fixing rod 1 and the external sleeve 4. It is connected in the lateral groove 11, the rotating sleeve 8 is threadedly connected to the side wall of the fixed sleeve 3, the two ends of the compression spring 9 respectively abut against the rotating sleeve 8 and the push plate 7, and a return spring 12 is sleeved on the fixed sleeve 3. The two ends of the return spring 12 respectively abut against the hexagonal sleeve 5 and the push plate 7. The clamping mechanism includes a contraction block 13 and a spring 14. There are multiple springs 14, and the multiple springs 14 are respectively connected between the pressure plate 6 and the contraction block 13. A contraction platform 15 is provided in the fixed sleeve 3, and a plurality of contraction grooves 16 are equidistantly opened on the contraction platform 15. The contraction block 13 is slidably connected in the contraction groove 16. A plurality of anti-slip strips 17 are provided on the side wall of the rotating sleeve 8, and the plurality of anti-slip strips 17 are respectively equidistantly arranged.

[0031] When the angle of the headrest 21 needs to be adjusted by fixing the insertion rod 2, the hexagonal sleeve 5 is inserted into the hexagonal groove 10, and then the rotating sleeve 8 is rotated to make the rotating sleeve 8 move on the fixed sleeve 3. Since the two ends of the compression spring 9 respectively contact the rotating sleeve 8 and the push plate 7, the multiple push plates 7 will be driven to move in the direction of the hexagonal sleeve 5, and then the shrinkage block 13 will slide along the shrinkage groove 16. The multiple pressure plates 6 will contract with each other, so that the pressure plates 6 will contact the insertion rod 2, thereby ensuring the fixation of the insertion rod 2, and then ensuring the angle between the adjustment sleeve 18 and the outer sleeve 4 is fixed. When the adjustment angle needs to be unlocked, the rotating sleeve 8 is first taken out, and under the action of the return spring 12, the multiple push plates 7 will be pushed, and then the shrinkage block 13 will expand along the shrinkage groove 16, thereby unlocking the fixation between the pressure plate 6 and the insertion rod 2, and then completing the adjustment process.

[0032] See also Figure 1 and Figure 2 As an implementation method of a head support device for a CT machine for a rotating mechanism: the rotating mechanism includes an adjusting sleeve 18 and an intermediate spring 19, the outer sleeve 4 is slidably connected to the adjusting sleeve 18, the intermediate spring 19 respectively abuts against the outer sleeve 4 and the adjusting sleeve 18, the insertion rod 2 is fixedly installed on the adjusting sleeve 18, the adjusting sleeve 18 is provided with an extension plate 20, the extension plate 20 is provided with a headrest 21, two adjusting sleeves 18 and two outer sleeves 4 are provided, and the two adjusting sleeves 18 and outer sleeves 4 are symmetrically arranged.

[0034] In summary, when the overall equipment is in use or operation: when it is necessary to fix the insertion rod 2 to adjust the angle of the headrest 21, since the hexagonal sleeve 5 is inserted into the hexagonal groove 10, the rotating sleeve 8 can be rotated to make the rotating sleeve 8 move on the fixed sleeve 3. Since the two ends of the compression spring 9 respectively abut against the rotating sleeve 8 and the push plate 7, the multiple push plates 7 will be driven to move in the direction of the hexagonal sleeve 5, and then the shrinkage block 13 will slide along the shrinkage groove 16, and the multiple pressure plates 6 will shrink against each other, so that the pressure plate 6 abuts against the insertion rod 2, thereby ensuring the fixation of the insertion rod 2, and then ensuring the angle fixation between the adjustment sleeve 18 and the outer sleeve 4. When it is necessary to unlock the adjustment angle, first the rotating sleeve 8 is taken out, and under the action of the return spring 12, the multiple push plates 7 will be pushed, and then the shrinkage block 13 will expand along the shrinkage groove 16, thereby unlocking the fixation between the pressure plate 6 and the insertion rod 2, and then completing the adjustment process.
