Description

Technical Field

[0001] The utility model relates to the technical field of head support and fixing devices for CT imaging inspection, in particular to a head support and fixing device for CT imaging inspection. Background Art

[0002] CT, or computer tomography, is a medical imaging technique. It uses an X-ray beam and a detector to rotate around the patient's body parts, collect data from different angles through X-rays, and reconstruct them into tomographic images after computer processing. These images can show the internal structure and abnormalities of the body, helping doctors diagnose diseases and formulate treatment plans.

[0003] The existing CT beds are for patients to lie down for examination, and therefore do not have the function of fixing the patient's head. When performing CT imaging examinations on some patients who are not conscious or have no autonomous control ability, the lack of fixation of the patient's head may cause motion artifacts in the CT scan image, affecting the quality of the scan. In addition, when a targeted examination of the head is required and the patient's head needs to maintain a certain posture, the lack of auxiliary fixation of the patient's head may make the patient feel uncomfortable. For this reason, we provide a head support and fixation device for CT imaging examinations. Utility Model Content

[0027] In this embodiment, by setting up the supporting mechanism 3, the patient's head in a suitable state can be fixed to ensure that the patient's head will not shake arbitrarily during the CT examination, thereby improving the clarity of the scanned image. At the same time, the threaded rod 33 is threadedly connected to the threaded tube 32, so that the threaded rod 33 remains stable after rotation, thereby achieving the purpose of supporting the patient's head. In addition, a rotating plate 35 is provided, and a rotating groove that matches the rotating plate 35 is opened inside the fixed block 34, so that when the threaded rod 33 rotates and moves, it will drive the fixed block 34 to gradually approach the patient without rotating. At the same time, a silicone pad 36 is fixedly connected to the fixed block 34, so that when the fixed block 34 contacts the patient's head, it will not cause damage to the patient's skin.

[0028] Example 2

[0029] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the adjustment mechanism 2 includes a cushion block 21, a fixing frame 22 is provided on the top of the cushion block 21, the cushion block 21 and the fixing frame 22 are both fixedly connected to the CT bed 1, an arc block 1 23 is provided inside the fixing frame 22, an arc block 24 is fixedly connected to the outer surface of the arc block 1 23, a slide groove matching the arc block 1 23 and the arc block 24 is provided on the fixing frame 22, bolts 25 are penetrated inside the fixing frame 22 and the arc block 1 23, the bolts 25 are slidably connected to the fixing frame 22, the bolts 25 are threadedly connected to the arc block 1 23, a through hole 26 is provided on the fixing frame 22, a threaded hole 1 27 is provided on the arc block 1 23, and a threaded hole 28 is provided on the arc block 1 23.

[0030] In this embodiment, by providing an adjustment mechanism 2, the position of the support mechanism 3 can be adjusted in a targeted manner according to the use requirements, and the arc block 1 23 and the arc block 24 can slide in the fixing frame 22, so as to achieve the purpose of moving the support mechanism 3. At the same time, a through hole 26, a threaded hole 1 27 and a threaded hole 28 are provided, so that the bolt 25 can be threadedly connected with the arc block 1 23 while passing through the fixing frame 22, thereby maintaining the stability of the support mechanism 3 after adjustment. In addition, the threaded hole 1 27 and the threaded hole 28 are provided at both ends of the arc block 1 23. Therefore, when the arc block 1 23 moves to the two ends of the fixing frame 22, the bolt 25 can be selected in a targeted manner according to the actual situation, so that the bolt 25 can limit the arc block 1 23 through the threaded hole 1 27 or the threaded hole 28.

[0031] Working principle:

[0032] like Figure 1-Figure 5As shown, when the utility model is in use, the patient first lies on the CT bed 1, and then the position of the support mechanism 3 is adjusted according to the patient's condition. If the patient needs to keep the head tilted to a certain extent, the arc block 1 23 and the arc block 24 slide in the fixing frame 22, and then the support mechanism 3 is adjusted to the rear of the patient's head after the tilt. At this time, the threaded hole 1 27 and the threaded hole 28 opened on the arc block 1 23 are aligned with the through hole 26 opened on the fixing frame 22, and then the bolt 25 is passed through the through hole 26 and screwed into one of the threaded hole 1 27 or the threaded hole 28. The threaded connection makes the supporting mechanism 3 in a stable state, and then the threaded rod 33 can be driven to rotate by turning the knob 37. Since the threaded rod 33 is threadedly connected to the threaded tube 32, the threaded rod 33 will remain stable after rotating and moving. At the same time, the rotation of the threaded rod 33 will drive the rotating plate 35 to rotate in the rotating groove opened inside the fixed block 34, and then the fixed block 34 will gradually approach the patient's head until the silicone pad 36 fits tightly with the patient's head and forms a supporting effect on the patient's head, and with the assistance of the pad 21, the patient's head is kept in a suitable state.

[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
