Description

Technical Field

[0001] This invention relates to the field of magnetic resonance imaging equipment, and more particularly to a magnetic resonance imaging chair and a magnetic resonance imaging device. Background Technology

[0002] Currently, most commercially available MRI scanning beds are connected to magnets in MRI machines. Although some MRI scanning beds are capable of lifting, moving, and other operations, their large size and weight make it difficult to disassemble and install them with the magnets. Therefore, it is not possible to transfer patients with limited mobility using MRI scanning beds. Patients still need medical staff assistance to move onto the MRI scanning bed during MRI scans. In addition, although there are some wheelchairs on the market specifically designed for MRI scans, their main function is to transport patients with limited mobility to the MRI scanning position. Afterward, medical staff still need to assist in transferring the patient to the MRI scanning bed, which is not convenient and can easily cause secondary injury to the patient during the transfer process.

[0003] In response to the problems of limited functionality in related technologies such as dedicated beds and wheelchairs for magnetic resonance imaging systems (magnetic resonance beds are only used for magnetic resonance scanning scenarios, and dedicated magnetic resonance wheelchairs are only used for transporting patients), medical beds and chairs are not suitable for magnetic resonance scanning scenarios and cannot meet the requirements of different treatment measures such as magnetic resonance scanning diagnosis, examination and treatment without moving the patient's body, which poses potential risks such as causing secondary harm to the patient.

[0004] Therefore, based on years of experience and practice in related industries, the inventor proposes a magnetic resonance imaging bed and chair and a magnetic resonance imaging device to overcome the shortcomings of the prior art. Summary of the Invention

[0057] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0058] Implementation Method 1

[0059] like Figures 1 to 15 As shown, the present invention provides a MRI chair, which includes a seat 1, a backrest 2, a leg rest 3, and at least one radio frequency coil adapter 6. The seat 1 is movable, and the backrest 2 and leg rest 3 are hinged to the seat 1, respectively, and are located on opposite sides of the seat 1. The radio frequency coil adapter 6 can be disposed on one or more of the seat 1, backrest 2, and leg rest 3 (depending on the actual installation position of the MRI radio frequency coil). The radio frequency coil adapter 6 is used to connect with the MRI head coil 100 and / or limb end cap. Coil 200 is adapted and connected; when the seat 1, backrest 2 and leg rest 3 are adjusted to a preset angle, the MRI bed chair is in wheelchair mode, and the patient can use the MRI bed chair in a sitting position; when the seat 1, backrest 2 and leg rest 3 are all adjusted to a horizontal position, the MRI bed chair is in hospital bed mode, and the patient can use the MRI bed chair in a lying position; during the MRI scan, the patient can move the MRI bed chair in a sitting or lying position to be close to the magnet 300, and the MRI bed chair in a lying position is connected to the magnet 300.

[0060] In this invention, by hinged backrest 2 and leg rest 3 to movable seat 1, the MRI bed chair is movable and can switch between wheelchair mode and hospital bed mode. When the seat 1 and backrest 2, and the seat 1 and leg rest 3 are adjusted to preset angles, the MRI bed chair is in wheelchair mode, allowing the patient to move while seated. When the seat 1, backrest 2, and leg rest 3 are all in a horizontal position, the MRI bed chair is in hospital bed mode, allowing the patient to lie down. Since the MRI bed chair includes a radio frequency coil adapter 6 that can be adapted to connect with the head coil 100 and / or limb coil 200 for MRI, during magnetic resonance imaging... During MRI, the patient can move the MRI chair in a sitting or lying position to be close to the magnet 300. The lying-positioned MRI chair engages with the magnet 300, allowing MRI imaging to be performed. The acquired signals are transmitted directly through the head coil 100 and / or limb coil 200, completing the entire MRI examination without requiring the patient to get up or move. This is convenient and efficient. The MRI chair of this invention combines the functions of an MRI scanning bed and a non-magnetic wheelchair, meeting the functional requirements of MRI scanning, pre-scanning procedures in a sitting position, and post-scanning procedures in a sitting position, avoiding potential harm to the patient from movement between different stages. Of course, the MRI chair of this invention also meets the needs of transferring patients in other examination and treatment scenarios.

[0061] In an optional embodiment of the present invention, such as Figures 1 to 4 As shown, the radio frequency coil adapter 6 includes a head coil adapter 601 that is adapted to connect with the head coil 100. The head coil adapter 601 is connected to the back panel 2, and the head coil adapter 601 and the seat panel 1 are located on opposite sides of the back panel 2. The head coil adapter 601 is positioned to match the head position of the patient on the MRI chair in a lying position. By adapting the head coil 100 to the head coil adapter 601, the MRI scan signal at the patient's head position can be received.

[0062] Furthermore, such as Figure 4As shown, the head coil adapter 601 is provided with at least one first positioning boss 6013. The first positioning boss 6013 is used to engage with at least one first positioning slot 1001 on the head coil 100, thereby facilitating the installation and disassembly of the head coil 100 and the head coil adapter 601. The number and position of the first positioning bosses 6013 can be adjusted according to the actual product to ensure stable assembly of the head coil 100 and the head coil adapter 601. The number and position of the first positioning slots 1001 are simply to match the first positioning bosses 6013. Alternatively, a slot structure can be provided on the head coil adapter 601, while a boss structure can be provided on the head coil 100.

[0063] Furthermore, such as Figure 3 As shown, the back panel 2 is provided with a first connecting part 201, and the head coil adapter 601 is provided with a second connecting part 6011. The first connecting part 201 and the second connecting part 6011 are rotatably connected by a pin 6012. When the patient uses the MRI chair in a sitting position (i.e., the MRI chair is in wheelchair mode), the head coil adapter 601 can be flipped to the back of the back panel 2. At this time, it is not necessary to install the head coil 100 to ensure the patient's comfort when using the MRI chair. When the patient uses the MRI chair in a lying position (i.e., the MRI chair is in bed mode), the head coil adapter 601 can be flipped to be on the same plane as the back panel 2. At this time, the head coil 100 can be installed so that the patient can undergo MRI scanning. When the head coil adapter 601 is flipped to be on the same plane as the back plate 2, the relative position of the head coil adapter 601 and the back plate 2 can be fixed by setting a fixing pin or fixing connector between the head coil adapter 601 and the back plate 2. The specific fixing structure is not limited in this invention. The pin 6012 can be made of, but is not limited to, a non-metallic material that can avoid magnetic resonance scanning artifacts during magnetic resonance imaging. The pin 6012 can be made of, but is not limited to, ceramic.

[0064] In an optional embodiment of the present invention, such as Figure 5 As shown, the radio frequency coil adapter 6 includes at least one limb coil adapter 602 that is adapted to and connected to the limb coil 200. The limb coil adapter 602 is connected to the seat 1 and / or leg rest 3. The limb coil adapter 602 can be matched to the patient's hand, wrist, leg, foot, etc. By adapting and connecting the limb coil 200 to the limb coil adapter 602, magnetic resonance scanning signals from other locations of the patient (such as the hand, wrist, leg, foot, etc.) can be received.

[0065] Furthermore, such as Figure 5As shown, the limb coil adapter 602 is provided with at least one second positioning slot 6021. The second positioning slot 6021 is used to engage with at least one second positioning boss 2001 on the limb coil 200, thereby facilitating the installation and disassembly of the limb coil 200 and the limb coil adapter 602. The number and position of the second positioning slots 6021 can be adjusted according to the actual product to ensure stable assembly of the limb coil 200 and the limb coil adapter 602. The number and position of the second positioning bosses 2001 are simply to ensure they match the second positioning slots 6021. Alternatively, a boss structure can be provided on the limb coil adapter 602, while a slot structure can be provided on the limb coil 200.

[0066] In an optional embodiment of the present invention, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 9 , Figure 10 As shown, the MRI chair also includes a base 5, a seat 1 that is height-adjustable and mounted on top of the base 5, and multiple casters 8 at the bottom of the base 5 to ensure that the MRI chair can be moved according to the patient's needs. The casters 8 can be manually propelled or electrically driven.

[0067] Furthermore, such as Figure 6 , Figure 10 As shown, a traction rail 9 is fixedly installed below the magnet 300, and casters 8 are used to connect and adapt to the traction rail 9. When the MRI chair is moved to a position close to the magnet 300, the casters 8 at the bottom of the base 5 can slide into the traction rail 9 and slide along the traction rail 9, thereby pushing the patient in a lying position to the scanning position inside the magnet 300. This achieves the connection and adaptation between the MRI chair and the magnet 300, so that the patient does not need to get up or move on their own during the MRI scan, avoiding secondary injury to the patient. Of course, the casters 8 can also be used to conveniently move the patient into or out of the scanning room when not scanning.

[0068] In an optional embodiment of the present invention, such as Figure 11 As shown, a first positioning part 202 is provided on the back panel 2. When the magnetic resonance imaging bed chair is in a reclining position, the first positioning part 202 is used to cooperate with the second positioning part 3001 on the magnet 300. Thus, during the sliding of the universal wheel 8 along the traction track 9, the relative position between the magnetic resonance imaging bed chair and the magnet 300 can be positioned to ensure the accuracy of the magnetic resonance scan.

[0069] Specifically, such as Figure 11As shown, the first positioning part 202 consists of multiple stepped protrusions located at the top edge of the back plate 2, and the second positioning part 3001 consists of multiple stepped grooves located on the inner wall of the magnet 300. When the back plate 2 moves to a preset position inside the magnet 300, the first positioning part 202 and the second positioning part 3001 cooperate and abut against each other, thereby limiting the continued movement of the magnetic resonance imaging bed and indicating that the magnetic resonance imaging bed has reached the preset scanning position.

[0070] In an optional embodiment of the present invention, such as Figure 9 As shown, a lifting seat 14 (or lifting rod) is provided between the seat 1 and the base 5. A first drive cylinder 15 is provided on the base 5. The piston rod of the first drive cylinder 15 is connected to the lifting seat 14. The first drive cylinder 15 serves as a power source and can drive the lifting seat 14 to move up and down, thereby realizing the adjustment of the height of the magnetic resonance imaging bed chair to meet the different height needs of patients during use.

[0071] Furthermore, such as Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 10 As shown, the magnetic resonance imaging bed chair also includes an outer cover 7. The bottom of the outer cover 7 is fixedly connected to the top of the base 5, and the outer cover 7 surrounds the outer side of the lifting seat 14 along the outer periphery of the lifting seat 14, which plays a protective role for the lifting seat 14 and makes the magnetic resonance imaging bed chair more aesthetically pleasing.

[0072] In an optional embodiment of the present invention, the base 5, the lifting seat 14, and / or the outer cover 7 may be made of, but is not limited to, non-magnetic materials or weakly magnetic metal materials to avoid signal interference, thereby meeting the working requirements of the magnetic resonance equipment and ensuring the accuracy of the detection. The base 5, the lifting seat 14, and / or the outer cover 7 may be made of, but is not limited to, metals such as stainless steel or aluminum alloy.

[0073] In an optional embodiment of the present invention, such as Figure 7 , Figure 8 As shown, a second drive cylinder 10 is disposed between the seat 1 and the backrest 2. The second drive cylinder 10 is used to adjust the seat 1 and the backrest 2 to form a first preset angle. A third drive cylinder 11 is disposed between the seat 1 and the leg rest 3. The third drive cylinder 11 is used to adjust the seat 1 and the leg rest 3 to form a second preset angle. The first and second preset angles can be set according to the patient's actual usage to meet the patient's different angle requirements between the seat 1 and the backrest 2 and between the seat 1 and the leg rest 3, thereby facilitating the switching between wheelchair mode and hospital bed mode for the MRI chair. Of course, based on the setting of the first and second preset angles, the usage needs of the patient in other examination and treatment scenarios can also be met.

[0074] Specifically, such as Figure 7 , Figure 8 As shown, the second drive cylinder 10 is fixedly mounted on the back of the seat plate 1, and the back of the back plate 2 is provided with a first push rod 12. The first push rod 12 includes at least a first segment 1201 connected to the back plate 2 and a second segment 1202 extending towards the outside of the back plate 2 in the direction close to the second drive cylinder 10. One end of the second segment 1202 is connected to the first segment 1201, and the second segment 1202 forms an angle with the first segment 1201. The other end of the second segment 1202 is connected to the piston rod of the second drive cylinder 10. By adjusting the extension and retraction of the piston rod of the second drive cylinder 10, the first push rod 12 can be pushed to rotate, thereby adjusting the first preset angle between the seat plate 1 and the back plate 2.

[0075] Specifically, such as Figure 7 , Figure 8 As shown, the third drive cylinder 11 is fixedly mounted on the back of the seat plate 1, and the back of the leg support plate 3 is provided with a second push rod 13. The second push rod 13 includes at least a third segment 1301 connected to the leg support plate 3 and a fourth segment 1302 extending towards the outside of the leg support plate 3 in the direction close to the third drive cylinder 11. One end of the fourth segment 1302 is connected to the third segment 1301, and the fourth segment 1302 forms an angle with the third segment 1301. The other end of the fourth segment 1302 is connected to the piston rod of the third drive cylinder 11. By adjusting the extension and retraction of the piston rod of the third drive cylinder 11, the second push rod 13 can be pushed to rotate, thereby adjusting the second preset angle between the seat plate 1 and the leg support plate 3.

[0076] In an optional embodiment of the present invention, such as Figure 10 As shown, the backrest 2 and seat 1, as well as the leg rest 3 and seat 1, are hinged together by hinges 16. This prevents accidents such as pinching hands when adjusting the first preset angle between the backrest 2 and seat 1, and the second preset angle between the leg rest 3 and seat 1, thus ensuring the safe use of the MRI chair.

[0077] In an optional embodiment of the present invention, such as Figure 1 , Figure 2 As shown, armrests 4 are provided on both sides of the seat 1.

[0078] In an optional embodiment of the present invention, the seat 1, backrest 2, leg rest 3, and / or radio frequency coil adapter 6 may be made of, but are not limited to, non-metallic materials that can avoid magnetic resonance scanning artifacts during magnetic resonance imaging, in order to meet the working requirements of the magnetic resonance equipment and ensure the accuracy of the detection. The base 5, lifting seat 14, and / or outer cover 7 may be made of, but are not limited to, fiberglass.

[0079] The specific embodiments of the magnetic resonance imaging bed chair of the present invention are as follows:

[0080] Taking a patient undergoing head scan diagnosis and TMS (transcranial magnetic stimulation) treatment as an example,

[0081] like Figure 12 As shown, the patient can be moved from the MRI bed-chair in wheelchair mode to the MRI scanning room, such as... Figure 13 As shown, before performing an MRI scan, the MRI chair is switched from wheelchair mode to bed mode, and a head coil 100 and / or limb coil 200 are fitted and installed. The patient wears the head coil 100 and / or limb coil 200. Figure 14 As shown, the MRI bed-chair in bed mode is moved to a position close to the magnet 300, and the casters 8 of the MRI bed-chair are slid into the traction track 9. The MRI bed-chair slides along the traction track 9 to the preset position. At this time, the patient moves to the designated scanning position within the magnet 300, and then the normal MRI scanning imaging operation is performed. After the MRI scanning imaging is completed, as... Figure 15 As shown, the magnetic resonance imaging (MRI) chair is removed from the magnet 300, the head coil 100 and / or the limb coil 200 are removed, and the MRI chair is switched from bed mode to wheelchair mode, allowing the patient to move.

[0082] Of course, after the patient completes the magnetic resonance imaging, the first preset angle between the seat board 1 and the back board 2 and the second preset angle between the seat board 1 and the leg support board 3 can be adjusted so that the patient can receive TMS treatment in a sitting position according to the diagnosis results.

[0083] The features and advantages of the magnetic resonance imaging bed chair of the present invention are as follows:

[0084] First, this MRI bed-chair can be used alone as a wheelchair for transporting patients, or it can be converted into a bed for use with the MRI machine without moving the patient. After the scan diagnosis is completed, it can be converted back into a wheelchair to transport the patient to other departments for treatment. The patient does not need to get up during the entire diagnosis and treatment process. This MRI bed-chair has good applicability and effectively avoids causing secondary harm to the patient.

[0085] Second, the MRI chair can be fitted with a MRI radio frequency coil. By adjusting the height and angle, the area of ​​the patient that needs to be diagnosed can be positioned within the scanning area of ​​the MRI device, ensuring accurate detection of the patient.

[0086] Third, this magnetic resonance imaging bed chair has a wide range of applications. It is compatible with the functions of a magnetic resonance imaging scanning bed and a non-magnetic wheelchair, which can conveniently meet the requirements of patients to undergo magnetic resonance imaging examinations or other examinations. At the same time, it can meet the needs of patients to transfer in different application scenarios such as detection and treatment.

[0087] Implementation Method 2

[0088] The present invention provides a magnetic resonance imaging device, which includes a magnetic resonance imaging bed chair, a magnetic resonance radio frequency coil and a magnet 300 as described above. The magnetic resonance radio frequency coil is used to connect with the radio frequency coil adapter 6 on the magnetic resonance imaging bed chair, and the magnet 300 is connected to the magnetic resonance imaging bed chair in a lying position.

[0089] Furthermore, the magnetic resonance radio frequency coil includes a head coil 100 and an end coil 200.

[0090] Furthermore, a traction track 9 is fixedly installed below the magnet 300. The traction track 9 can be adapted to the magnetic resonance imaging bed and chair, and plays a role in traction and positioning of the magnetic resonance imaging bed and chair.
