Description

Technical Field

[0001] This invention relates to the field of magnetic resonance imaging, and more particularly to a patient support device and a mobile magnetic resonance imaging system. Background Technology

[0002] Magnetic resonance imaging (MRI) systems require installation in a fixed, shielded MRI room, so patients needing MRI scans must be transported to the MRI room for examination. Existing technology provides a mobile MRI system that can be moved to the patient's location for examination, eliminating the need for patient transport and greatly improving the speed and safety of the examination.

[0003] In the prior art, Chinese invention patent CN110123323B provides a patient transport vehicle and a patient transport method. The patient transport vehicle includes: a movable support frame; a bed board support plate disposed on the movable support frame; and a movable bed board, adjustablely connected to the bed board support plate along its length. The bed board support plate is provided with a positioning and docking mechanism located at its end. The positioning and docking mechanism includes a docking pin located below the bed board support plate and a docking socket located below the bed support plate of the medical device. The docking pin and the docking socket are compatible, so that the bed board support plate and the bed support plate are on the same straight line and connected, forming an integrated structure to serve as a sliding support for the movable bed board. In this technical solution, by adjusting the position of the movable bed board along the length of the bed board support plate, the movable bed board can be positioned to extend into the medical device for medical examination, especially for MRI examination. This patient transport vehicle not only avoids inconvenience to the patient's walking and movement, but also avoids secondary injury to the patient.

[0004] When using the above technical solutions, the pins on the patient-supporting bed board need to be matched with the sockets on the MRI equipment. This requires medical staff to constantly adjust the height and left and right position of the patient-supporting bed board. In addition, the pins and sockets are located at the bottom of the bed board, which obstructs the view. Medical staff need to bend over to check and adjust them, which makes the docking of the patient-supporting bed board with the MRI equipment take up a lot of time and affects the efficiency of the examination. Summary of the Invention

[0005] To address the technical problem of the long time patients spend inside the MRI machine during MRI examinations in the prior art, this invention provides a patient support device and a mobile MRI system that eliminates the need for medical staff to accurately position the patient-supporting bed, saving time on positioning and docking, and improving examination efficiency.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a patient support device, including a support part, a roller provided at the lower part of the support part, and further including: a movable plate, the movable plate being disposed on the upper part of the support part and being movable along the length direction of the support part, the movable plate being used for transverse transport of the patient; a transport assembly, the transport assembly being disposed on the movable plate and being movably disposed on the movable plate, the transport assembly being perpendicular to the movement direction of the movable plate, the transport assembly being used for longitudinal transport of the patient; and a shielding assembly, the shielding assembly including a fixed part and a movable part, one end of the movable part and the fixed part being able to be attached to a mobile magnetic resonance imaging system, one end of the fixed part being disposed on the support part, the movable part being slidably disposed on the fixed part, when the movable part overlaps with the fixed part, the shielding assembly is in an open state, and when one end of the movable part contacts the support part, the shielding assembly is in a closed state and the cross-section of the shielding assembly has an arched structure.

[0007] This invention achieves longitudinal transport of patients by using a moving plate, a conveying assembly, and a shielding assembly. It eliminates the need for medical staff to accurately adjust the position of the bed board that originally carried the patient, saving a significant amount of time spent on position adjustments and improving diagnostic efficiency.

[0008] Furthermore, the support part is slidably connected to the movable plate, and the support part is also provided with a rack. The rack is arranged parallel to the moving direction of the movable plate. The movable plate is provided with a motor, and the motor is connected to a gear. The gear meshes with the rack.

[0009] Furthermore, the conveying assembly includes a support plate for supporting the patient. A synchronous belt is connected to both ends of the support plate. The synchronous belt surrounds a driving pulley and a driven pulley. Both the driving pulley and the driven pulley are rotatably mounted on the moving plate. The two driving pulleys are respectively connected to the output shaft of motor two through corresponding transmission shafts. Motor two is a dual-output shaft motor.

[0010] This invention enables synchronous rotation of the synchronous belts at both ends through a dual-output shaft motor drive, ensuring that the support plate does not tilt when moving.

[0011] Furthermore, the support plate has horizontally arranged connecting shafts at both ends, the connecting shafts are close to the fixed part, the ends of the connecting shafts extend into the movable plate, the connecting shafts can move along the movable plate, the connecting shafts are connected to the corresponding synchronous belts, and the two connecting shafts have different heights.

[0012] Furthermore, a rotating shaft is provided at one end of the support plate, and the rotating shaft is arranged parallel to the rack. When the conveyor belt is transported around the rotating shaft and the support plate, the conveyor belt is wrapped around the support plate.

[0013] The present invention facilitates the transfer of patients to the support plate by setting a conveyor belt on the support plate, reducing the distance the support plate extends under the patient's body, thereby reducing the movement size of the support plate and the size and space occupied by the entire support device.

[0014] Furthermore, conductive foam is provided on the surface of the moving part that is in contact with the supporting part, on the end face of the moving part near the magnetic resonance imaging device, and on the end face of the fixed part near the magnetic resonance imaging device.

[0015] This invention prevents magnetic leakage from the gaps in the shielding component itself and from the gaps between the shielding component and the support and magnetic resonance imaging device by setting conductive foam.

[0016] Furthermore, the fixing part is movably disposed on the support part.

[0017] The present invention features a fixed part that is movable on the support part, which makes it easy for medical staff to push the shielding cover to check the patient's condition and provides sufficient space for performing some treatment operations on the patient.

[0018] Secondly, the present invention also provides a mobile magnetic resonance imaging system, including a magnetic resonance imaging device and the aforementioned patient support device. Both the magnetic resonance imaging device and the support device are provided with rear rollers at their lower parts. The support device is connected to the magnetic resonance imaging device. The magnetic resonance imaging device includes an examination cavity, in which a coil is movably disposed. When the moving plate is movable, it examines the examination cavity and pushes the coil to move.

[0019] Furthermore, a positioning light is provided at the top of the examination cavity, which can project a image onto a position on the patient's face, and the positioning light is electrically connected to the control module of the magnetic resonance imaging device.

[0020] This invention can accurately locate the patient's position by setting a positioning light, thus avoiding inaccurate patient positioning that could affect the accuracy of diagnosis.

[0021] Furthermore, a visual camera is also provided at the top of the examination cavity, and the visual camera is electrically connected to the control module of the magnetic resonance imaging device.

[0022] This invention uses a visual camera to intelligently determine whether the patient has moved into position, enabling the system to automatically perform the next action, thus enhancing the system's intelligence.

[0023] As can be seen from the above technical solutions, the present invention has the following advantages: This invention provides a patient support device and a mobile magnetic resonance imaging (MRI) system. Through the movement of the support plate, the transport assembly, and the shielding assembly, longitudinal transport of the patient is achieved, eliminating the need for medical staff to precisely adjust the position of the original patient-bearing bed, saving significant time and improving diagnostic efficiency. The dual-axis motor drive ensures synchronous rotation of the belts at both ends, preventing tilting of the support plate during movement. The conveyor belt on the support plate facilitates patient transfer, reducing the distance the support plate extends under the patient's body, thus minimizing the movement of the support plate and reducing the overall size and space occupied by the support device. Conductive foam prevents magnetic leakage from gaps in the shielding assembly itself and between the shielding assembly and the support and MRI devices. The movable mounting of the fixing part on the support allows medical staff to easily move the shielding cover to view the patient and provides sufficient space for treatment procedures. Positioning lights accurately locate the patient, preventing inaccurate patient positioning from affecting diagnostic accuracy. A visual camera intelligently determines whether the patient has moved into position and automatically proceeds to the next step, enhancing the system's intelligence. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent. Specific Implementation Method 1 like Figure 1 and Figure 2 As shown in the figure, this specific embodiment provides a patient support device, including a support part 2, a movable plate 6, a conveying assembly, and a shielding assembly 1. The support part 2 is provided with rollers 3 at its lower part. The movable plate 6 is disposed on the upper part of the support part 2 and is movable along the length direction of the support part 2. The movable plate 6 is used for transverse patient transport. The conveying assembly is disposed on the movable plate 6 and is movably disposed on the movable plate 6. The moving direction of the conveying assembly is perpendicular to the moving direction of the movable plate 6. The conveying assembly is used for longitudinal patient transport. For transporting patients; the shielding assembly 1 includes a fixed part 101 and a movable part 102. One end of the movable part 102 and the fixed part 101 can be attached to the mobile magnetic resonance imaging system. One end of the fixed part 101 is disposed on the support part 2. The movable part 102 is slidably disposed on the fixed part 101. When the movable part 102 overlaps with the fixed part 101, the shielding assembly 1 is in an open state. When one end of the movable part 102 contacts the support part 2, the shielding assembly 1 is in a closed state and the cross-section of the shielding assembly 1 has an arched structure.

[0033] This specific embodiment achieves longitudinal transport of the patient through the functions of the moving plate 6, the conveying component, and the shielding component 1. It eliminates the need for medical staff to accurately adjust the position of the original patient-bearing bed, saving significant time and improving diagnostic efficiency. This embodiment uses patient transport on one side of the support section 2, which, compared to existing technologies that transport patients from one end, offers several advantages: First, it eliminates the need for a transfer bed; the patient's original bed or stretcher can be used directly, avoiding multiple patient transfers. Second, it eliminates the need for precise positioning; only the original bed board needs to be roughly flush with the conveying component, saving time. Third, the original bed or stretcher continues to provide support during transport, enhancing safety. Fourth, compared to transporting from one end to the MRI machine, the distance traveled from one side is shorter, further reducing the time required for patient arrival.

[0034] like Figure 1 and Figure 4 As shown, in this specific embodiment, the support part 2 is slidably connected to the moving plate 6. Specifically, two slide rails are arranged opposite each other on the upper part of the support part 2, and a slide groove is provided on the moving plate 6 at a position corresponding to the slide rails. The slide rails extend into the slide grooves and can slide relative to each other. The support part 2 is also provided with a rack, which is arranged parallel to the moving direction of the moving plate 6. A motor is provided on the moving plate 6, and a gear is connected to the motor. The gear meshes with the rack. In this specific embodiment, the motor is a servo motor, which has high operating accuracy and facilitates accurate control of the patient's stopping position.

[0035] like Figures 2 to 4As shown, in this specific embodiment, the conveying assembly can adopt the following specific structure: the conveying assembly includes a support plate 5, which is used to support the patient. Synchronous belts 19 are connected to both ends of the support plate 5. The synchronous belts 19 are surrounded by a driving pulley 16 and a driven pulley 20. Both the driving pulley 16 and the driven pulley 20 are rotatably mounted on the moving plate 6. The two driving pulleys 16 are respectively connected to the output shaft of a second motor 14 via corresponding transmission shafts 15. The second motor 14 is a dual-output shaft motor. Connecting shafts 17 are horizontally arranged at both ends of the support plate 5. The connecting shaft 17 is located near the fixed part 101. The end of the connecting shaft 17 extends into the guide groove at the end of the moving plate 6. The connecting shaft 17 can move along the guide groove. The connecting shaft 17 is connected to the corresponding synchronous belt 19. The two connecting shafts 17 have different heights; the higher connecting shaft 17 is connected to the upper layer of the corresponding synchronous belt 19, and the lower connecting shaft 17 is connected to the lower layer of the corresponding synchronous belt 19, ensuring unidirectional movement. Multiple support rollers 502 are rotatably mounted at both ends of the support plate 5. The support rollers 502 extend into the guide groove and can... The device is capable of moving along the guide groove and rotating to reduce friction; the synchronous rotation of the synchronous belts at both ends is achieved by a dual-output shaft motor, ensuring that the support plate 5 does not tilt during movement; furthermore, to reduce the size of the support plate 5 extending into the lower part of the patient, thereby reducing the space occupied by the device, a rotating shaft 18 is rotatably mounted on one end of the support plate 5 via a bracket. The rotating shaft 18 is connected to the motor 3 via a belt drive assembly. The rotating shaft 18 is arranged parallel to the rack. The motor 3 is located at the lower part of the support plate 5. When the conveyor belt 4 surrounds the rotating shaft 18 and the support plate 5, the conveyor belt 4 is a toothed belt. The 18-circle design has multiple teeth that mesh with the transmission belt. With this design, the support plate 5 extends to the lower part of the patient's body. Then, through the action of the conveyor belt 4, the patient is completely transferred from the original bed or stretcher to the support plate 5, and then from the support plate 5 to the moving plate 6. This effectively reduces the distance the support plate 5 extends. Due to the shortened lever arm, the strength requirements of the support plate 5 are also reduced, achieving lightweight design. In this specific embodiment, the support plate 5 is made of carbon fiber material, which is high in strength and lightweight. Furthermore, the end of the support plate 5 near the patient is provided with a guide ramp 501, which facilitates access to the lower part of the patient's body.

[0036] like Figure 2As shown in this specific embodiment, the inner surface of the fixing part 101 is provided with an arc-shaped guide rail, which is connected to the moving part 102. Conductive foam is provided on the surface of the moving part that is in contact with the supporting part, the end face of the moving part 102 near the magnetic resonance imaging device 8, and the end face of the fixing part 101 near the magnetic resonance imaging device 8. By providing conductive foam, gaps can be filled to avoid magnetic leakage. Both the moving part 102 and the fixing part 101 are made of composite layer material, including two supporting layers, with a metal wire mesh between the two supporting layers. The supporting layers are made of transparent fiberglass. Furthermore, to facilitate medical staff to adjust the patient's position and perform corresponding treatment operations on one side, the fixing part 101 is movably set on the supporting part 2 via a corresponding guide rail. When needed, medical staff can push the shielding component 1 to one end to expose the patient.

[0037] The device also includes a remote control, which is electrically connected to motor one, motor two 14 and motor three. Specific Implementation Method Two like Figure 5 As shown, this specific embodiment provides a mobile magnetic resonance imaging system, including a magnetic resonance imaging device 8 and a patient support device according to the first embodiment. Both the magnetic resonance imaging device 8 and the support 2 are provided with rear rollers 3 at their lower parts for easy movement. The support 2 is connected to the magnetic resonance imaging device 8. The magnetic resonance imaging device 8 includes an examination cavity 12. A coil 9 is movably disposed in the examination cavity 12 via corresponding guide rails. When the moving plate 6 is movable, it pushes the coil 9 to move within the examination cavity 12. A limit stage is provided at the port of the examination cavity 12 to prevent the coil 9 from detaching.

[0039] like Figure 5 As shown, to facilitate the determination of whether the patient has moved to the correct position, a positioning light 10 is provided at the top of the examination cavity 12. The positioning light 10 can project a shadow on the patient's face at a set position (between the eyebrows). The positioning light 10 is electrically connected to the control module of the magnetic resonance imaging device 8. When the patient is longitudinally transported to the appropriate position by the moving plate 6, the projection of the positioning light 10 falls on the patient's forehead. The distance between this position and the position of the coil 9 during examination is a qualified distance, so as to avoid the patient moving too far or too far, which would affect the examination.

[0040] Preferably, the lower part of the support 2 is provided with a receiving cavity, and a magnetic seat 13 is provided in the receiving cavity. The adsorption surface of the magnetic seat 13 is flush with the surface of the support 2 and the magnetic resonance imaging device 8. An iron block is provided at the corresponding position of the magnetic resonance imaging device 8. The connection is achieved by the adsorption of the two. During maintenance, the operator can reach into the receiving cavity to rotate the switch of the magnetic seat 13 to demagnetize it.

[0041] like Figure 5As shown, in order to facilitate the movement of the movable plate 6 within the examination cavity 12, a guide rail and a rack are provided on the bottom surface of the examination cavity 12. The guide rail on the bottom surface of the examination cavity 12 is flush with the guide rail of the support part 2 and aligned horizontally. The rack on the bottom surface of the examination cavity 12 is collinear with the rack on the support part 2.

[0042] To enhance the intelligence level of this system, a visual camera 11 is also installed at the top of the examination cavity 12. The visual camera 11 is located behind the positioning light 10 (in the direction in which the patient enters the examination cavity 12). The visual camera 11 is electrically connected to the control module of the magnetic resonance imaging device 8. When the visual camera 11 captures an image of the patient, it is determined that the patient has been successfully transferred. The positioning light 10 is turned on and positioning begins. When the image of the patient's head is projected at the center of the eyebrows, it means that the patient has moved into position and the moving plate 6 needs to stop moving.

[0043] To improve reliability, a laser sensor is installed inside the examination cavity 12 at a position opposite to the position of the coil 9 during examination. The laser sensor is electrically connected to the control module and determines whether the coil 9 has reached the accurate position.

[0044] The usage method of this system is as follows: When an MRI scan is required, the patient's original bed or stretcher is moved to one side of the support plate 2, and the bed height is adjusted to be roughly level with the support plate 5. The relevant button on the remote control is pressed, and the support plate 5 extends under the patient's body. Once the support plate 5 is in position, the conveyor belt 4 is activated to transfer the patient onto the support plate 5. The support plate 5 is then retracted onto the moving plate 6. After it is in position, the moving plate 6 is moved towards the examination cavity 12, pushing the coil 9 into the cavity. When the visual camera 11 acquires the patient's image information, the positioning light 10 illuminates. When the image acquired by the visual camera 11 shows the projection at the center of the forehead, the moving plate 6 stops moving. Medical staff place the coil 9 on the patient's head. After the coil 9 is in place, the moving plate 6 continues to move. When the motor reaches the set moving length, it automatically stops moving. At this time, the laser sensor also emits a corresponding electrical signal. Medical staff observe the examination cavity and close the shielding component 1; the examination begins.

[0045] As can be seen from the above specific embodiments, the present invention has the following beneficial effects: 1. Through the action of the moving plate 6, the conveying component, and the shielding component 1, the longitudinal transport of the patient is realized, eliminating the need for medical staff to accurately adjust the position of the original bed board that carries the patient, saving a lot of time for position adjustment and improving the efficiency of diagnosis and treatment. 2. The synchronous belts 19 at both ends can be driven by a dual-output shaft motor to ensure that the support plate 5 does not tilt when it moves. 3. By setting a conveyor belt 4 on the support plate 5, it is easier to transfer patients to the support plate 5, reduce the distance that the support plate 5 extends under the patient's body, thereby reducing the moving size of the support plate 5 and reducing the size and space occupation of the entire support device. 4. By setting conductive foam, magnetic leakage is prevented from the gaps in the shielding component 1 itself and the gaps between it and the support part 2 and the magnetic resonance imaging device 8. 5. The fixed part 101 is movable in the support part 2, which makes it easy for medical staff to push the shielding cover to check the patient's condition, and provides enough space to perform some treatment operations on the patient; 6. By setting the positioning light 10, the patient's location can be accurately located, avoiding inaccurate patient location that could affect the accuracy of diagnosis; 7. By setting up the visual camera 11, the system can intelligently determine whether the patient has moved into position and enable the system to automatically perform the next action, thereby improving the intelligence level of the system.
