TECHNICAL FIELD
[0001] The present application relates to the technical field of medical auxiliary equipment, in particular to an auxiliary transfer device for CT examination. BACKGROUND
[0002] The existing auxiliary transfer device for CT examination is a special device for assisting patients to safely move between the sickbed and the CT examination bed, which is usually composed of an adjustable support frame, a transfer platform and a transmission mechanism. The support frame is made of high-strength aluminum alloy or stainless steel, which is light and has strong bearing capacity. The height of the platform can be adjusted through a hydraulic rod or an electric push rod according to the height difference between the sickbed and the examination bed, so as to achieve smooth connection. The device is deeply integrated into the biological, medical health big data sharing platform and the health-related information system and cloud platform, and can upload patient transfer data in real time to provide basic information for the intelligent diagnosis and treatment ecological system. The surface of the transfer platform is paved with anti-slip soft pads, and the edges are provided with foldable guardrails, which can not only ensure the stability of the patient during transfer, but also facilitate the assistance of medical staff. Some devices are equipped with electric conveyor belts or rolling rollers, which can be controlled by buttons to move the platform slowly and reduce the patient's limb movement. Some devices are designed with a rotatable transfer plate to adapt to the side transfer needs of patients of different sizes. At the same time, the device integrates a comprehensive biological verification system using artificial intelligence technology, which can quickly identify patient information and provide personalized transfer solutions for special patients. Such devices are generally equipped with brake wheels to prevent sliding after being fixed. The overall structure is easy to disassemble and sterilize, meeting the sanitary requirements of the medical environment. It provides convenient support for CT examination transfer of patients with limited mobility, postoperative rehabilitation and other patients, and promotes the perfection of the intelligent diagnosis and treatment ecological system combining online and offline.
[0003] The existing auxiliary transfer device for CT examination has obvious limitations in actual use. The overall structure is fixed and lacks deformation adjustment capability, resulting in narrow application scenarios. The transfer platform of such devices is usually an integrated rigid frame, and the length and width cannot be adjusted according to the patient's size (such as obese patients, children) or the size of the examination bed. If the patient's limbs cannot fully fit the platform, it is easy to cause bumps during transfer. At the same time, the height adjustment range of the device is limited, and it is difficult to adapt to the height of the examination bed of different types of CT machines (the difference often reaches 20-30 cm). Medical staff need to manually lift and move the patient to make up for the gap, increasing the labor intensity and the risk of accidents. In addition, the fixed structure cannot be folded or disassembled, making it difficult to turn over in a small examination room, and occupying a lot of storage space when idle. More importantly, for patients who need to maintain a specific body position, the fixed device cannot adjust the inclination angle or disassemble the transfer, which may cause discomfort due to forced changes in body position, greatly limiting the auxiliary ability of the device in complex situations. This brings certain disadvantages to people's use process. In order to solve the problems of the prior art, we propose an auxiliary transfer device for CT examination. SUMMARY

DETAILED DESCRIPTION
[0018] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.
[0019] Embodiment one, as Figures 1-12As shown, when it is necessary to move the patient to the CT table, the second winding disc 219 is driven to rotate by the first servo motor 218, the first linkage bar 220 is wound by the second winding disc 219, a pulling force is applied to the first linkage bar 220, the second fixed column 223 is driven by the first linkage bar 220 around the first rolling wheel 221, the second fixed column 223 and the second middle layer plate 212 are driven to slide along the fourth limiting groove 216 and the fourth limiting block 217 of the second bottom plate 211; at the same time, due to the movement of the second middle layer plate 212, a force is applied to the second linkage bar 225, the third fixed column 226 is driven by the second linkage bar 225 around the second rolling wheel 224, the third fixed column 226 and the second upper top plate 213 are driven to slide along the third limiting groove 215 and the third limiting block 214 of the second middle layer plate 212, the platforms of the two sides of the second bottom plate 211, the second middle layer plate 212 and the second upper top plate 213 are realized to be telescopic, at this time, since the second winding disc 219 and the first winding disc 23 are driven by the first servo motor 218 through the universal joint 210, when the second winding disc 219 is driven by the first servo motor 218, the first winding disc 23 is synchronously moved, and since the first winding disc 23, the first linkage bar 220, the first rolling wheel 221, the first fixed column 222, the second fixed column 223, the second rolling wheel 224 and the second linkage bar 225 are arranged as a group, there are two groups, and they are arranged on the two sides of the first bottom plate 21, the first middle layer plate 26 and the first upper top plate 27 respectively, so that the first linkage bar 220 is wound by the first winding disc 23, a pulling force is applied to the first linkage bar 220, the second fixed column 223 is driven by the first linkage bar 220 around the first rolling wheel 221, the second fixed column 223 and the first middle layer plate 26 are driven to slide along the first limiting groove 24 and the first limiting block 25 of the first bottom plate 21, at the same time, due to the movement of the first middle layer plate 26, a force is applied to the second linkage bar 225, the third fixed column 226 is driven by the second linkage bar 225 around the second rolling wheel 224, the third fixed column 226 and the first upper top plate 27 are driven to slide along the second limiting groove 29 and the second limiting block 28 of the first bottom plate 21, the other platform is realized to be synchronously telescopic, the patient is moved to the upper side of the CT bed, and then the device is reset by reverse operation, at the same time, the device integrates a comprehensive biological verification system applying artificial intelligence technology, can quickly identify patient information, and combines a molecular biological information analysis processing system to provide personalized transfer scheme for special patients.
[0020] In embodiment two, as Figures 13-17As shown, when it is necessary to move the patient from the device, in order to prevent the patient from slipping, the second servo motor 33 drives the first synchronous wheel 34 and the second synchronous wheel 35 to rotate the first threaded rod 36, causing the first threaded block 37 to move the first protective baffle 38 horizontally. At this time, the third servo motor 318 is not started. When the first protective baffle 38 moves towards the second protective baffle 317, the second threaded rod 321 applies pressure to the second limiting post 316, pushing the second protective baffle 317, the second limiting post 316, the first positioning block 315, and the locking rod 314 to slide out of the locking groove 313. When the locking rod 314 slides out of the locking groove 313, since the second threaded block 39 is in contact with the positioning frame 41, the positions of the second threaded block 39 and the first limiting post 310 remain unchanged. The movement of the second protective baffle 317 realizes the movement of the connecting rod 312. Pulling open, the movement of connecting rod 312 causes the second rotating rod 32 and the second protective baffle 317 to deflect, causing the second rotating rod 32 and the second protective baffle 317 to flatten. When the second protective baffle 317 is flattened, the threaded groove 322 and the second threaded rod 321 correspond to each other and are in contact. Then, the third servo motor 318 is started, and the second threaded rod 321 is driven to rotate through the third synchronous wheel 319 and the fourth synchronous wheel 320. Then, through the contact between the second threaded rod 321 and the threaded groove 322, the second protective baffle 317 applies a force to the locking rod 314 toward the locking groove 313, thereby causing the locking rod 314, the first positioning block 315, the second limiting post 316, and the second protective baffle 317 to slide toward the inside of the locking groove 313. When the second protective baffle 317 moves toward the locking groove 313, it passes under the patient and is pulled out from the patient's lower side.
[0021] Example 3, as Figures 18-20 As shown, when the device needs adjustment, the electric telescopic rod 48 can be activated. The electric telescopic rod 48 pushes the slider 49 to slide within the slide groove 410. The sliding of the slider 49 causes the position of the third limiting post 412 to change. Since positioning frames 41 are fixedly installed on the lower side of the second lower base plate 211, and the positioning frames 41 are connected by auxiliary rods 42, when the position of the third limiting post 412 changes, it pushes the fourth fixed post 44 to move the linkage rod 43 and the auxiliary transport device 2 to one side. At this time, through the limiting of the positioning frame 41, the two sets of second lower base plates 211, second middle layer plates 212, and second upper top plates 213 are respectively offset and deflected, so that one set deflects upward and the other set deflects downward, thus deforming into the shape of a wheelchair.

Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
