Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and more particularly to an auxiliary support device for lung CT examination. Background Technology

[0002] CT stands for Computed Tomography, a medical imaging technique that uses X-rays to scan specific parts of the human body from multiple angles and then reconstructs cross-sectional images using a computer.

[0003] During a lung CT scan, the standard patient position is supine with arms raised or placed at the sides. This position aims to open the chest cavity and prevent soft tissue from obscuring key imaging areas such as the lung apex, mediastinum, and pleura, ensuring complete visualization of pulmonary nodules, ground-glass opacities, and bronchial lesions. However, maintaining this position for extended periods can lead to shoulder fatigue, muscle tension, and even involuntary micro-movements, especially for elderly, frail, or patients with respiratory diseases. Poor comfort significantly increases the difficulty of cooperation during the examination, thus affecting image quality and diagnostic accuracy. Therefore, a support device is necessary.

[0004] Currently, most traditional CT scan auxiliary support devices simply place the arm directly on the head or place the patient's arm on the examination table. When the patient raises their upper limb, there is no effective support point for the shoulder. The arm is easily sore and shaky when suspended for a long time, which can cause body displacement, produce motion artifacts in the scan image, and reduce the clarity of the lung image. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one object of the present invention is to provide an auxiliary support device for lung CT examination.

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] An auxiliary support device for lung CT examination according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figures 1-5As shown, an auxiliary support device for lung CT examination according to an embodiment of the present invention includes a scanner body 1 and a support mechanism 2.

[0022] The support mechanism 2 includes a sliding table 21, a fixed block 22, a support component 23, a buffer component 24, and a rotating component 25.

[0023] The sliding stage 21 is installed on the inspection table of the scanner body 1, the fixing block 22 is installed on the outer wall of the sliding stage 21 near the scanning area, the support component 23 is set on the fixing block 22, multiple sets of buffer components 24 are provided, each set of buffer components 24 is symmetrically arranged on the inner wall of the support component 23, and the rotating component 25 is set on the buffer component 24.

[0024] It should be noted that when a prolonged examination of the patient's chest cavity is required, the patient needs to keep their arms positioned above their head or in the air for an extended period, which can increase soreness in the shoulders and arms, causing involuntary swaying and affecting the clarity of the CT scan images, leading to inaccurate diagnostic results. This device can provide elastic support for the patient's arms and can be adjusted to fit different body types, effectively improving the comfort of the examination process.

[0025] Specifically, when the scanner body 1 needs to be used, medical staff first help the patient lie flat on the examination bed 51 and ask if the patient needs support pads 62 for particulate support. If the patient's neck or shoulders need additional support, the two locking posts 61 are inserted into the pre-set locking slots 52 on the examination bed 51, so that the support pads 62 are stably locked in the appropriate position, providing close support for the patient. If no additional support is needed, the support pads 62 can be directly removed from the locking slots 52 without affecting routine examination operations. Then, the patient places both upper limbs on the hand pads 3 of the rotating component 25, and the pressure of the patient's arms is applied... When the buffer spring 241 is compressed, it undergoes elastic deformation. The support block 251 rotates downward along the rotating column 232, causing the limiting groove 252 to squeeze the buffer spring 241 at one end of the limiting column 242. The elastic deformation of the buffer spring 241 absorbs the pressure on the support block 251, relieving local pressure on the arm and improving placement comfort. At the same time, the rotation angle of the support block 251 can be automatically adjusted according to the weight of the patient's arm to adapt to the placement habits and limb height of different patients. After the adjustment is completed, the scanner body 1 is started and the examination bed 51 is sent into the scanning area through the sliding stage 21 for imaging.

[0026] It should be noted that all parts of the support mechanism 2 are made of medical-grade polymer materials or aluminum alloys, and the surfaces are polished and coated with antibacterial coatings to ensure good biocompatibility, structural strength and ease of cleaning in the CT examination environment.

[0027] In one embodiment of this application, such as Figure 2 As shown, the support assembly 23 includes a fixed plate 231, a rotating column 232, and a fixing component 4.

[0028] The fixing plate 231 is installed on both sides of the fixing block 22, one end of the rotating column 232 passes through the fixing plate 231, and the other end of the rotating column 232 is installed on the fixing block 22. The fixing component 4 is set on the inner wall of the fixing plate 231.

[0029] In one embodiment of this application, such as Figure 2 As shown, each set of buffer components 24 includes a buffer spring 241 and a limiting post 242.

[0030] The buffer spring 241 is installed on the inner wall of the fixed plate 231, and one end of the limiting post 242 is connected to the fixed plate 231.

[0031] In one embodiment of this application, such as Figure 2 As shown, the rotating component 25 includes a support block 251.

[0032] The support block 251 is installed on the fixed plate 231. The support block 251 has a limiting groove 252, and the limiting groove 252 is engaged with the other end of the limiting post 242. The support block 251 has a rotating groove 253, and the rotating groove 253 is engaged with the rotating post 232.

[0033] Specifically, when a patient experiences numbness or discomfort in their arm during a prolonged examination, they can place their arm on the support block 251. Under the pressure of the patient's arm, the buffer spring 241 is compressed and undergoes elastic deformation. The support block 251 rotates downward along the rotating column 232, causing the limiting groove 252 to press against the buffer spring 241 at one end of the limiting column 242. The elastic deformation of the buffer spring 241 absorbs the pressure on the support block 251, relieving local pressure on the arm and improving placement comfort. At the same time, the rotation angle of the support block 251 can be automatically adjusted according to the weight of the patient's arm to adapt to different patients' placement habits and limb height.

[0034] In one embodiment of this application, such as Figure 2 As shown, the rotating assembly 25 also includes a hand pad 3.

[0035] The hand pad 3 is installed on the outer wall of the support block 251.

[0036] It should be noted that the hand pad 3 is filled with medical memory foam and wrapped with breathable and skin-friendly antibacterial medical fabric. It can not only provide even support and cushioning for the arm, reducing the local pressure caused by long-term examination, but also facilitate daily cleaning and disinfection, avoiding cross-infection.

[0037] In one embodiment of this application, such as Figure 3As shown, the fixing component 4 includes a support plate 41, a headrest 42, and a protective pad 43.

[0038] The support plate 41 is installed on the inner wall of the fixing plate 231, the headrest 42 is installed on the examination side wall of the support plate 41, and the protective pad 43 is installed on the side wall of the headrest 42 that contacts the patient's head.

[0039] It should be noted that the protective pad 43 is made of medical-grade memory foam, which can conform to the contour of the patient's head and neck, provide uniform support, avoid prolonged pressure causing redness and discomfort, and maintain the stability of the head position, reducing artifacts caused by head displacement during scanning.

[0040] In one embodiment of this application, such as Figure 4 As shown, the scanner body 1 also includes a locking component 5.

[0041] The locking assembly 5 includes an examination bed 51 and a protective assembly 6.

[0042] The examination bed 51 is installed on the examination side wall of the sliding table 21. The examination bed 51 has a locking groove 52, and the locking groove 52 is locked and connected to the protective component 6. The protective component 6 is set on the examination bed 51.

[0043] In one embodiment of this application, such as Figure 5 As shown, the protective component 6 includes a locking post 61 and a support pad 62.

[0044] There are two locking posts 61, which are symmetrically installed in the locking groove 52, and the support pad 62 is installed on the locking posts 61.

[0045] It should be noted that the support pad 62 is made of elastic and breathable medical silicone material, with evenly distributed breathable pores inside and anti-slip texture on the surface, which can improve the comfort of patients during use and provide a close and stable support for the patient's chest and back, adapting to the examination needs of patients of different body types.

[0046] Specifically, when examining a patient with lumbar lesions, the support pad 62 can be inserted into the corresponding locking groove 52 through the locking post 61 to support the patient's lumbar region, preventing discomfort caused by the patient's lumbar region being suspended and affecting the stability of the body position during the examination, thereby ensuring the clarity of the CT scan image.

[0047] It should be noted that the scanner body 1 also has a locking groove 52 on its worktable. When the support pad 62 is not in use, medical staff can lock the support pad 62 into the locking groove 52 on the worktable through the locking post 61.

[0048] Working principle: When a patient experiences numbness or discomfort in their arm during a prolonged examination, they can place their arm on the support block 251. Under the pressure of the patient's arm, the buffer spring 241 is compressed and undergoes elastic deformation. The support block 251 rotates downward along the rotating column 232, causing the limiting groove 252 to press against the buffer spring 241 at one end of the limiting column 242. The elastic deformation of the buffer spring 241 absorbs the pressure on the support block 251, relieving local pressure on the arm and improving placement comfort. At the same time, the rotation angle of the support block 251 can be automatically adjusted according to the weight of the patient's arm to adapt to different patients' placement habits and limb height.

[0049] When examining a patient with lumbar lesions, the support pad 62 can be inserted into the corresponding locking groove 52 through the locking post 61 to support the patient's lumbar region, preventing the patient's lumbar region from being suspended and causing discomfort, affecting the stability of the body position during the examination, and thus ensuring the clarity of CT scan imaging.
