[0034] like Figures 1 to 9 As shown, this invention provides a CT scan patient support structure and device based on vertical and horizontal dual-use adaptability, including a base structure 1, a lifting column structure 2, a horizontal drive structure 3, a CT scan structure 4, a support component structure 5, a tilting armrest structure 6, a body posture monitoring component 7, a support frame disassembly structure 8, and a position monitoring component 9. The support component structure 5, in conjunction with the tilting armrest structure 6, provides reliable support under different scanning postures. Simultaneously, the lifting column structure 2, in conjunction with the CT scan structure 4, and the horizontal drive structure 3, in conjunction with the support component structure 5, effectively improves adaptability to both vertical and horizontal states. Furthermore, it can effectively adjust scan deviation based on vertical or horizontal states, significantly improving the overall flexibility of the architecture. In addition, the body posture monitoring component 7 and the position monitoring component 9 enable automatic positioning, collision protection, and intelligent exposure parameter setting, further enhancing the overall applicability, convenience, and intelligence of the device, and improving its overall functionality. Specific settings are as follows: Please refer to Figures 1 to 3The base structure 1 is made of high-strength alloy material and has a rectangular plate structure. Its bottom is equipped with anti-slip and shock-absorbing pads to increase friction with the ground, reduce equipment vibration, and provide a stable support foundation for the whole device. The four corners of the base structure 1 are provided with mounting holes, which can be installed with the ground through expansion bolts to further improve installation stability.

[0035] As a preferred embodiment, the base structure 1 can be made of, but is not limited to, cast iron or stainless steel.

The thickness of the base structure 1 is set to 10~15cm to ensure that it has sufficient strength to bear the overall weight of the equipment and the load during operation.

[0036] The lifting column structure 2 is controllably positioned at the center of the base structure 1. The lifting column structure 2 can be controllably positioned and rotated around the axis based on the base structure 1 to achieve the switching between vertical and horizontal scanning states of the lifting column structure 2 and its auxiliary structures. The lifting column structure 2 is a vertical column structure with a hollow interior to accommodate the drive transmission components and circuit lines that output the first vertical displacement kinetic energy. A scanning guide rail 21 is provided on one side of the lifting column structure 2. The scanning guide rail 21 extends along the length of the lifting column structure 2 and serves as the directional sliding base for the CT scanning structure 4.

[0037] Two sets of horizontal drive structures 3 are provided. Each set of horizontal drive structures 3 includes a shift drive motor 31 and a lead screw assembly 32. The shift drive motor 31 is a servo motor with high-precision speed and position control capability. The two sets of shift drive motors 31 are respectively located at the top and bottom positions of the lifting column structure 2, and their output shafts are oriented to the side. The two sets of lead screw assemblies 32 are respectively assembled at the top and bottom positions of the lifting column structure 2. Each set of lead screw assemblies 32 includes a lead screw and a lead screw nut. The lead screw is rotatably connected to the lifting column structure 2, and one end of each set of lead screws is respectively connected to the output shaft of the two sets of shift drive motors 31 through a coupling. The lead screw nut is screwed onto the lead screw and is slidably connected to the lifting column structure 2, so as to realize that the shift drive motor 31 drives the lead screw to rotate, and then drives the lead screw nut to move along the lead screw axis according to the lead screw principle.

[0038] The CT scanning structure 4 has a scanning frame and a scanning slide 41 mounted on one side of the scanning frame. The scanning frame is located on the side of the scanning slide 41 away from the lifting column structure 2. The scanning frame is equipped with an emitting device and a detection device for scanning and imaging X-rays. The inner side of the scanning slide 41 is provided with a scanning groove that is adapted to the scanning guide rail 21. The scanning slide 41 is slidably connected to the scanning guide rail 21 through the scanning groove. The scanning slide 41 is also connected to the first displacement kinetic energy output end of the lifting column structure 2 through a transmission assembly, so that the CT scanning structure 4 can be linearly moved along the lifting column structure 2.

[0039] As another preferred embodiment, the scanning guide rail 21 can be a ball bearing guide rail, which has a low overall friction coefficient, high precision and longer service life, and can further improve the movement accuracy and smoothness of the scanning slide 41; the shift drive motor 31 can be equipped with an encoder to provide real-time feedback on the motor speed and position information, realize closed-loop control, and ensure that the movement position accuracy of the scanning slide 41 is controlled within ±0.1mm.

[0040] Please refer to Figure 1 , Figure 4 and Figure 9 The support component structure 5 includes a first support frame 51, a second support frame 52, a bed support board 53, and a transmission guide slider 54. The first support frame 51 and the second support frame 52 are both frame structures. The second support frame 52 is arranged parallel to the first support frame 51 to form a double support structure. One end of the first support frame 51 and one end of the second support frame 52 are provided with a transmission guide slider 54. The first support frame 51 and the second support frame 52 are respectively connected to the screw nuts at the top and bottom positions of the lifting column structure 2 through the transmission guide slider 54, so as to ensure that the support component structure 5 as a whole can effectively achieve horizontal adjustment based on the horizontal drive structure 3.

[0041] An installation space is formed between the first support frame 51 and the second support frame 52. The support bed plate 53 is detachably and positioned within the installation space between the first support frame 51 and the second support frame 52. The support bed plate 53 extends to the inner side of the scanning gantry in the CT scanning structure 4 to maintain adaptability and collaborative conversion for both vertical and horizontal use according to different scanning scenarios. Furthermore, it can effectively adjust the scanning based on the vertical or horizontal state, significantly improving the overall flexibility of the architecture.

[0042] More specifically, both the first support frame 51 and the second support frame 52 are made of high-strength aluminum alloy, which is lightweight and strong, ensuring that the support bed board 53 has sufficient strength and rigidity in the horizontal direction, avoiding deformation of the bed board due to the weight of the patient, and ensuring the stability of the scanning process; the support bed board 53 is made of carbon fiber composite material, which has better overall X-ray penetration and can reduce scanning imaging interference and artifacts.

[0043] As another preferred embodiment, the surface of the support bed board 53 may be provided with anti-slip texture to increase the friction between the patient and the bed board and prevent the patient from sliding during the scanning process; the thickness of the support bed board 53 is set to 1~2cm, the width is set to 40~50cm, and the length is set to 180~200cm to flexibly adapt to patients of different body types.

[0044] Please continue to refer to this. Figure 4 The flip-up armrest structure 6 includes a first armrest 61, a second armrest 62, a telescopic frame part 63, and a flip-up drive assembly 64. The first armrest 61 is adapted to be mounted on the inner side of the other end of the first support 51, and the second armrest 62 is adapted to be mounted on the inner side of the other end of the second support 52, with the two arranged opposite to each other. The second armrest 62 also has a telescopic frame part 63, which can extend and retract along the extension length direction of the second armrest 62 to adjust the size of the second armrest 62 to adapt to patients of different body types.

[0045] Two sets of flip drive components 64 are provided. Each set of flip drive components 64 includes a flip motor and a reducer. The two sets of flip motors and reducers are respectively located on the first support frame 51 and the second support frame 52. The input end of the reducer is connected to the output shaft of the flip motor. The output ends of the two sets of reducers are respectively connected to the transfer shaft of the first support frame 61 and the transfer shaft of the second support frame 62 to drive the first support frame 61 and the second support frame 62 to rotate around the axis, so as to realize the automatic flipping action of the support frame. When the patient needs to get on or off the bed, the drive support frame can be controlled to flip to the outside to facilitate entry and exit. Or, in the scanning state, the drive support frame can be controlled to flip to the inside limit to protect the patient in position.

[0046] The flip drive assembly 64 is also equipped with a torque sensor, which is connected to the output drive assembly of the flip motor and the control module circuit. The torque sensor can detect the magnitude of the motor output torque in real time. When the patient is unable to stand up on his own, the control module can control the flip motor to apply a certain torque based on the detection data of the torque sensor. The patient is pressed against the support bed board 53 by the armrest with a predetermined pressure, which helps the patient maintain stability and avoids excessive pressure that may cause discomfort to the patient.

[0047] As an optional solution in this embodiment, the surface of the handrail of the flip handrail structure 6 can be covered with a soft protective cover. The protective cover is made of medical-grade silicone, which is soft and comfortable, and can improve the user experience of patients. It also has the characteristics of antibacterial and easy cleaning. The measurement range of the torque sensor is set to 0~50N·m, and the measurement accuracy is controlled within ±0.1N·m to effectively ensure accurate detection of torque.

[0048] Please refer to Figures 5 to 7 The support frame disassembly and assembly structure 8 includes magnetic suction blocks 81, magnetic suction bases 82, and limiting pins 83. Two sets of magnetic suction blocks 81 are respectively located at the top and bottom edges of the supporting bed board 53, and are made of permanent magnet material, possessing stable magnetic force. Magnetic suction bases 82 are respectively located inside the first support frame 51 and the second support frame 52. The shape of the magnetic suction base 82 matches the shape of the magnetic suction blocks 81, and the inner wall of the magnetic suction base 82 is provided with magnetic metal material, allowing the magnetic suction blocks 81 to be magnetically attached and connected to the magnetic suction base 82. This achieves locking and magnetic co-fixation between the supporting bed board 53 and the first and second support frames 51, thereby more effectively limiting the displacement of the supporting bed board 53 in all directions.

[0049] The magnetic card block 81, magnetic card holder 82, and support bed board 53 are all provided with corresponding positioning pin holes. The limiting pin 83 is sequentially inserted into the positioning pin holes of the magnetic card holder 82, magnetic card block 81, and support bed board 53, thereby further improving the assembly stability of the support bed board 53. One end of the limiting pin 83 is provided with a pull ring for easy insertion and removal. When it is necessary to remove the support bed board 53, simply pull out the limiting pin 83 and lift the support bed board 53 upwards to remove it from between the first support frame 51 and the second support frame 52. The operation is convenient and quick.

[0050] As another optional solution in this embodiment, the magnetic force of the magnetic card block 81 can be selected according to actual needs to ensure that it can achieve initial fixation without making disassembly difficult due to excessive magnetic force; the limiting pin 83 can be made of stainless steel, which has good wear resistance and corrosion resistance, and extends service life.

[0051] Please continue to refer to this. Figure 4 The body posture monitoring component 7 includes a weighing sensor and a distance sensor. Both the weighing sensor and the distance sensor are mounted on the top of the second support frame 52, corresponding to the area where the patient's feet are placed. The weighing sensor and the distance sensor are respectively connected to the control module circuit, which can measure the patient's weight data and height data in real time, and transmit the data to the control module.

[0052] The ranging sensor is set to either an infrared ranging sensor or a laser ranging sensor. The control module can calculate the patient's BMI value based on the weight data measured by the weighing sensor and the height data measured by the infrared or laser ranging sensor. The BMI value reflects the degree of obesity in a person. Generally, the more obese the patient, the greater the exposure dose required. The control module provides recommended exposure parameters (such as voltage, current, etc.) based on different BMI values. Medical staff can adjust the exposure parameters according to the actual situation to ensure the production of high-quality CT images. When the input parameters deviate significantly from the recommended parameters, the control module will remind the user through audio and visual prompts to reduce the risk of exceeding the dosage and further protect the patient's health.

[0053] As a preferred embodiment, the weighing sensor has a measurement range of 0~200kg and a measurement accuracy controlled within ±0.5kg, which can accurately measure data of patients with different weights; the control module can store data such as the patient's height, weight, BMI value and exposure parameters, which is convenient for medical staff to query and statistically analyze later.

[0054] The control module is the core control unit of the entire device. It can be a PLC controller or an industrial computer with built-in control programs and algorithms. It is used to receive data from various sensors, process and analyze it, and control the actions of various execution components according to preset logic, including but not limited to the shift drive motor 31, the flip motor, and the scanning frame. The control module is also equipped with a touch screen, which is mounted on the lifting column structure 2. Parameter settings, mode selection, and other operations are performed through the touch screen.

[0055] As another preferred embodiment, the control module may have network communication capabilities, enabling it to connect to the hospital's information management system, realize the sharing and transmission of patient data, and improve diagnostic and treatment efficiency.

[0056] Please refer to Figure 8 and Figure 9 The point monitoring component 9 is mounted at the bottom of the first support frame 51, and the point monitoring component 9 includes, but is not limited to, a camera, an infrared ranging sensor or a laser ranging sensor. The monitoring input end of the point monitoring component 9 is directed towards the length direction of the support bed board 53, so as to achieve complete image capture of the patient's body center b and the scanning frame center hole a.

[0057] The point monitoring component 9 is connected to the control module circuit. The control module has a built-in image recognition algorithm that can process the images captured by the camera, identify the contours of the patient's body center b and the scanning frame center hole a, and calculate the deviation δp in the Y direction between the body center b and the center of the scanning frame center hole a in pixels. Given the actual diameter D of the scanning frame center hole a and the diameter Dp of the center hole in pixels in the image, the pixel deviation is converted into the actual deviation δ using the formula: δ=δp / Dp×D. Based on the calculated actual deviation δ, the control module controls the horizontal drive structure 3 to move, which in turn moves the support component structure 5 to align the patient's body center b with the scanning frame center hole a, achieving automatic positioning and ensuring the quality of the scanned image.

[0058] The point monitoring component 9 is also used to prevent the patient from colliding with the scanning gantry. During the scanning process, the camera acquires an image every 100 milliseconds, and the control module processes the image in real time to calculate the relative position of the patient's body contour and the contour of the center hole a of the scanning gantry. When it is determined that the patient's contour and the center hole contour intersect or the minimum distance is less than the safe distance, the control module immediately controls the scanning gantry to stop moving and end the scanning to avoid harming the patient. When there is no risk of collision, the monitoring continues until the scanning gantry movement ends.

[0059] As an alternative to this embodiment, the camera can be a high-definition industrial camera, which features high resolution and high frame rate to ensure the clarity and real-time performance of image acquisition.

[0060] The measurement range of the infrared or laser rangefinder is set to 1.2~2.2m, and the measurement accuracy is controlled within ±1mm, enabling accurate measurement of data from patients of different heights.

[0061] Please refer to Figures 10 to 12 The present invention also provides a CT scanning method based on vertical and horizontal dual-purpose adaptation, which specifically includes the following steps: When a vertical scan is required, the patient stands in the body posture monitoring component 7 area of ​​the second support frame 52. At this time, the weighing sensor measures the patient's weight, and the infrared or laser rangefinder measures the patient's height. The control module calculates the BMI value and sets the exposure parameters according to the preset ratio. The flip drive component 64 is then controlled to flip the first support frame 61 and the second support frame 62 inward to form a torso limit. At the same time, the position monitoring component 9 acquires images of the patient's body center b and the scanning frame center hole a in real time. The control module calculates the Y-axis deviation between the body center b and the scanning frame center hole a, and controls the horizontal drive structure 3 to move the support component structure 5 to achieve automatic positioning correction. After positioning is completed, the lifting column structure 2 drives the CT scanning structure 4 to start vertical scanning. During the scanning process, the camera monitors the relative position of the patient and the scanning frame in real time, thereby effectively preventing collisions.

[0062] When a horizontal scan is required, the lifting column structure 2 is directly driven to rotate based on the base support structure 1. Then, the position monitoring component 9 continues to acquire images of the patient's body center b and the scanning frame center hole a in real time, and the support component structure 5 is automatically corrected and positioned again based on the Y-axis deviation between the body center b and the scanning frame center hole a. Finally, the CT scanning structure 4 completes the horizontal scan.

[0063] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
