Description

Technical Field

[0001] The invention patent relates to the field of medical auxiliary equipment, specifically a CT imaging examination headrest. Background Art

[0002] In the key link of medical diagnosis, CT imaging examination, the stable fixation and precise positioning of the patient's head are undoubtedly the cornerstones to ensure image clarity and diagnostic accuracy. However, the design of traditional headrests has obvious limitations in this regard. First, its fixation method is often limited to a simple fixation plate or pillow. This "one-size-fits-all" design ignores the diversity of patient head shapes and sizes, resulting in poor fixation effect, which may affect the patient's comfort and reduce the accuracy of the examination due to head shaking. Secondly, although some headrests try to add angle adjustment functions, the operation is complicated and the accuracy is limited. It is difficult for doctors to quickly and accurately adjust the position of the patient's head during the examination, which limits the flexibility and efficiency of the examination to a certain extent. Furthermore, most traditional headrests rely on manual operation for fixation and adjustment, with a low degree of automation, which not only increases the workload of medical staff, but also may introduce errors due to human factors, affecting the examination results. It is particularly important that in the high-radiation environment of CT examination, the magnetic and radiation safety of the equipment is crucial. The deficiencies of traditional headrests in material selection and demagnetization may cause patients to be subjected to unnecessary electromagnetic interference during the examination, increasing potential health risks.

[0003] Therefore, in view of these limitations, developing a more flexible, accurate, automated and safe headrest for CT imaging examination has become an important issue to improve the quality of medical services and ensure patient safety.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Figure 1-Figure 2 : Embodiment: Detailed implementation of a head support for CT imaging examination 1. Overview This embodiment describes in detail the specific structure, assembly method and working principle of a head support for CT imaging examination, aiming to provide a head support device that can flexibly adjust the angle, is convenient for fixing the patient's head and is safe and free of magnetic interference.

[0016] 2. Structural composition 1. Head support plate 3 Materials: Use lightweight and high-strength materials such as carbon fiber or aluminum alloy to ensure load-bearing capacity while reducing overall weight.

[0017] Design: The headrest surface is designed in an ergonomic arc to increase patient comfort.

[0018] 2. Pillow 4 Material: Soft and comfortable memory foam, covered with removable and washable medical-grade fabric.

[0019] Installation: Fixed to the head support plate by Velcro or zipper for easy replacement and cleaning.

[0020] 3. Fixing plate 2 Material: Same as the head support plate, ensuring the stability of the overall structure.

[0021] Design: A mounting cavity 12 is provided at the bottom for mounting power components such as a motor and a screw.

[0022] 4. Rotating components The first connecting rod 7 has one end welded or bolted to the center of the bottom of the head support plate 3 .

[0023] Connecting shaft 8: High-precision bearings ensure smooth and noiseless rotation.

[0024] The second connecting rod 9 has one end welded or bolted to the top center of the fixing plate 2 , and the other end is rotatably connected to the connecting shaft 8 .

[0025] 5. Angle adjustment component The adjusting rod 5 is made of high-strength alloy material, one end of which is rotatably connected to the side of the head support plate 3 through the upper rotating shaft 6, and the other end is connected to the transition sliding rotating shaft 10.

[0026] Upper rotating shaft 6: fixed on the side of the head support plate to ensure that the adjusting rod can rotate freely around it.

[0027] The transition sliding shaft 10 is designed as a shaft body with threads, and is slidably connected with the slide groove 11 of the motor 1 and threadedly connected.

[0028] 6. Motor 1 and power components Motor 1: A low-noise, high-precision stepper motor is selected and precisely controlled by an external control system.

[0029] The slide groove 11 is provided on the motor housing and cooperates with the transition sliding shaft 10 to realize the composite motion of sliding and rotating.

[0030] The screw 13 is installed in the installation cavity 12 of the fixed plate 2 and is fixedly connected to the output end of the motor. The screw 13 drives the transition sliding shaft 10 to move along the slide groove 11 by rotating.

[0031] 3. Working Principle Initial state: the head support plate 3 is connected to the fixed plate 2 through a rotating assembly, the cushion 4 is fixed on the head support plate, and the patient's head is placed on the cushion.

[0032] Angle adjustment: The external control system sends a command to the motor 1 .

[0033] The motor 1 is started, driving the screw 13 to rotate.

[0034] The rotation of the screw rod 13 drives the transition sliding shaft 10 to slide in the slide groove 11 through the threaded connection, and at the same time, a rotational motion is generated due to the action of the thread.

[0035] The combined movement of the transition sliding shaft 10 drives the adjusting rod 5 to rotate around the upper shaft 6, thereby changing the angle between the head supporting plate 3 and the fixing plate 2.

[0036] Fixation and repositioning: After the angle is adjusted to the desired position, the motor stops working and the position of the head support plate is fixed by a locking mechanism of the rotating component, such as a spring locking device.

[0037] After the inspection is completed, the motor is controlled to rotate in the reverse direction through the external control system to reset the head support plate to the initial state.

[0038] 4. Demagnetization Overall demagnetization: The head support plate 3, the fixing plate 2, the pillow 4 and all metal parts are demagnetized before assembly to ensure that no magnetic interference is generated during the CT examination.

[0039] V. Conclusion The CT imaging examination headrest provided in this embodiment realizes flexible fixation and angle adjustment of the patient's head during the examination process through the design of precise rotating components and angle adjustment components. At the same time, it undergoes strict demagnetization treatment to ensure the accuracy of the examination results.
