Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and more particularly to a sealing device for magnetic resonance examination. Background Art

[0002] Magnetic resonance imaging (MRI) systems are the safest and clearest clinical imaging method for infants. Congenital encephalopathy and acquired factors, such as hypoxic-ischemic encephalopathy caused by amniotic fluid aspiration during childbirth, pose significant threats to infants' physiological and cognitive development. Early diagnosis and intervention are crucial, and therefore, a high percentage of infants undergo MRI examinations. Currently, whole-body MRI systems for infant scanning have many drawbacks, primarily manifested as:

[0003] First, the current mainstream equipment has an aperture for adult patients (generally 60cm~75cm), and the radio frequency coil used is also large-aperture for adults (the radio frequency coil includes a transmitting coil and a receiving coil. The closer the receiving coil is to the imaging site, the higher the signal-to-noise ratio (SNR), that is, the better the imaging quality). Therefore, the imaging quality of adult large-aperture magnetic resonance imaging equipment is slightly inferior for small infants.

[0004] Second, infants belong to a special group and require special care (such as constant temperature and humidity, etc.) during MRI examinations, which is more important for the physiological health of infants.

[0005] Third, MRI scans are noisy, and to prevent infants from becoming agitated, sedatives are often used. While these can put infants into a deep sleep and keep them still, they can also be life-threatening. Furthermore, the noise can potentially damage infants' hearing.

[0006] Fourth, for critically ill premature infants / neonates who need to be cared for and treated in infant incubators, although magnetic resonance imaging is particularly necessary to assist in disease diagnosis, their vital signs are unstable and even slight movement or exposure may put them in danger.

[0007] In summary, how to provide a box suitable for infant MRI examination is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to provide a sealing device for magnetic resonance examination, which improves the noise reduction effect of the box body, can avoid the use of sedatives during magnetic resonance scanning examinations, and reduce the damage caused to the examinee by noise and sedatives; when the box cover is opened relative to the end cover, the sealed box assembly will not move with the box cover, and will not cause secondary damage to the examinee; in addition, during the process of the bed board carrying the examinee turning in and out, the cooperation of the slide groove can achieve a non-exposure and non-contact transfer, reducing the damage to the examinee during the transfer process. Therefore, the sealing device for magnetic resonance examination provided by the present invention can be applied to infant magnetic resonance examinations.

Therefore, the sealing device for magnetic resonance imaging provided by the present invention can be applied to infant magnetic resonance imaging. Of course, by changing the size, it can also be used for adult magnetic resonance imaging.

[0049] Please refer to Figure 1-15 .

[0050] This specific embodiment discloses a sealing device for magnetic resonance examination, comprising:

[0051] The box cover assembly is provided with a box cover 12 and an end cover 1. The box cover 12 is movable relative to the end cover 1 to realize the opening and closing of the box cover assembly. The box cover 12 and the end cover 1 are both shell structures of at least two layers, and the shells of adjacent layers are filled with sound insulation material.

[0052] The sealed box assembly is located inside the box cover assembly and is provided with a box body 32, a sealing cover 23 that can be opened and closed and is provided on the box body 32, a slide 27 that cooperates with the bed plate 29 to be transferred, and a radio frequency coil 26;

[0053] The functional box assembly 3 is connected to the end cover 1 and is provided with a constant temperature and humidity control module, a vital signs monitoring module and a respiratory support system to provide a constant temperature and humidity environment inside the sealed box assembly and control the gas circulation inside the sealed box assembly.

[0054] It should be noted that the sound insulation material can be sound insulation damping glue, or other sound insulation materials that meet the requirements; preferably, for the convenience of observation, the shell of the box cover 12 can be set as a multi-layer transparent shell, and the sound insulation material can be set as a transparent sound insulation damping glue; or the shell of the box cover 12 and the shell of the end cover 1 can be set as a multi-layer transparent shell, and the sound insulation material can be set as a transparent sound insulation damping glue.

[0055] Preferably, in order to avoid the occurrence of acoustic resonance and enhance the noise intensity, each layer of the shell of the box cover 12 can be set to different thicknesses, and each layer of the shell of the end cover 1 can be set to different thicknesses.

[0056] Preferably, the box cover 12 can be set as an integrally formed cylindrical structure with an opening only at one end, which can further improve the noise reduction effect; here, the integrally formed refers to that the shell of the box cover 12 has no breakpoints, and the multiple layers of the shell do not contact each other. The box cover 12 can be set as a cylindrical structure with a U-shaped cross section, and only an opening is set at one end in the length direction, of course, it can also be other shapes, which is determined according to the actual situation.

[0057] Preferably, the box cover 12 and the end cover 1 can be set as a structure with three layers of shell, and two layers of sound insulation damping glue are sandwiched in the middle.

[0058] As shown in Figure 11 , the shell of the box cover 12 is three layers of second organic glass 19, and the second sound insulation damping glue 35 is sandwiched between adjacent layers of second organic glass 19, and the axes of the three layers of second organic glass 19 coincide; as shown in Figure 15 , the shell of the end cover 1 is three layers of first organic glass 6, and the first sound insulation damping glue 34 is sandwiched between adjacent layers of first organic glass 6.

[0059] As shown in Figure 14 , the side of the end cover 1 facing the box cover 12 is provided with a sealing element to improve the sealing effect of the contact between the box cover 12 and the end cover 1. The sealing element can be a sealing strip 11 or a sealing ring, which is determined according to the actual situation, and will not be described here.

[0060] Preferably, the functional box assembly 3 further comprises an alarm control system, which can send warning information when the environment in the sealed box assembly does not meet the setting requirements or when the inspector has abnormal movements in the sealed box assembly.

[0061] When using the sealing device for magnetic resonance imaging provided in this embodiment, first, the functional box assembly 3 is used to provide the sealed box assembly with gas of constant humidity, temperature, and oxygen content, so as to form a constant temperature, constant humidity, and suitable environment in the sealed box assembly; the box cover 12 is moved so that the box cover 12 and the end cover 1 are in an open state, and the box body 32 is connected to the infant incubator or other structure that allows the examinee to be transferred without exposure through the relay tube; the sealing cover 23 of the sealed box assembly is opened, and the bed board 29 carrying the examinee is matched with the slide groove 27 in the sealed box assembly, and the bed board 29 is pushed into the box body 32 along the slide groove 27. Buckle the sealing cover 23; push the box cover 12 so that the box cover 12 fits tightly with the end cover 1; start the conveyor belt on the MRI scanning bed 4 to send the entire box body 32 into the MRI equipment for MRI scanning; after the MRI scanning is completed, start the conveyor belt on the MRI scanning bed 4 to send the entire box body 32 out of the MRI equipment, open the box cover 12, connect the box body 32 to the infant incubator or other structure that can be used to transfer the examinee without exposure through the relay tube, open the sealing cover 23, and pull the bed board 29 carrying the examinee out to the infant incubator or other structure that can be used to transfer the examinee without exposure.

[0062] Compared with the prior art, the sealing device for magnetic resonance examination provided by this specific embodiment has a structure of at least two shell layers, and the adjacent shell layers are filled with sound insulation materials. When the sound waves pass through the multiple layers of shells and sound insulation and damping glue from the outside of the box, they are attenuated layer by layer, which greatly reduces the vibration of the sound waves and the noise reaching the inside of the box. This can improve the noise reduction effect, avoid the use of sedatives during magnetic resonance scanning, and reduce the damage caused to the examiner by noise and sedatives. The provision of a constant temperature and humidity environment can meet the requirements of examiners who have stricter requirements on environmental quality, especially patients or infants with relatively weak bodies. It effectively avoids accidents caused by the environment not meeting the requirements during the magnetic resonance examination. In addition, when the box cover 12 is opened and closed, the sealed box assembly does not move with the box cover 12, so that the radio frequency coil 26 and the end cover 1 remain stationary relative to the scanning bed, and no secondary injury is caused to the examiner. When the bed plate 29 moves in or out of the sealed box assembly, the box body 32 can be connected to the infant incubator or other structures that can enable the examiner to be transferred without exposure, and the slide 27 cooperates with the bed plate 29 to be transferred, so as to realize the non-exposure and non-contact transfer of infants, children or adult examinees, avoiding damage to the examiner's environment and injury to the examiner during the transfer process.

[0063] Based on the above embodiments, Figure 10As shown, the support plate 2 can be connected to the side of the end cover 1 facing the box cover 12, and the sealed box assembly is rotatably arranged on the support plate 2. The upper surface of the support plate 2 is provided with a circumferential rotator 21, which can be a non-metallic non-magnetic material thrust ball bearing. The top surface of the thrust ball bearing is provided with a bearing plate 22 to support the sealed box assembly. The sealed box assembly is rotatably arranged on the support plate 2 through the thrust ball bearing.

[0064] In use, the sealed box assembly can be rotated relative to the support plate 2 to facilitate the movement of the bed plate 29 into or out of the sealed box assembly.

[0065] A gas circulation channel can be provided at the lower part of the support plate 2, and the inlet and outlet of the gas are respectively arranged at both ends. A stable and uniform gas flow can be formed in the sealed box assembly.

[0066] As shown in Figure 1 , 6 , 7, the sealed device for magnetic resonance examination is provided as a box suitable for infant magnetic resonance examination. The functional box assembly 3 is connected to the side of the end cover 1 away from the box cover 12. The functional box assembly 3 contains a constant temperature and humidity control module, a gas circulation control module, a vital sign monitoring module, an alarm control system and a breathing support system. The functional box assembly 3 is connected to the sealed box assembly through an electrical line. The gas circulation control module is connected to the sealed box assembly through a gas pipeline to ensure the gas supply for the infant. The gas pipeline includes an air inlet pipe and an air outlet pipe. The end cover 1 is a multi-layer laminated structure composed of a first organic glass 6 and a first sound insulation damping glue. The end cover 1 has a passage hole, and a plug 7 is embedded in the passage hole. The plug 7 is made of sound insulation material and has an air inlet hole 8, an air outlet hole 9 and a wire hole 10. The air inlet hole 8 is used for the air inlet pipe to pass through, the air outlet hole 9 is used for the air outlet pipe to pass through, and the wire hole 10 is used for the electrical line to pass through, so as to minimize the noise transmitted to the box 32 through the end cover 1.

[0067] As shown in Figure 6 , the support plate 2 is horizontally connected to the lower part of the end cover 1, and the support plate 2 is a rectangular plate for supporting the radio frequency coil 26 and the sealed box assembly. The lower surface of the support plate 2 is provided with a pulley 33, which can be a U-shaped pulley. The inner side wall of the second organic glass 19 of the innermost layer of the box cover 12 has a sliding rail parallel to the axis of the second organic glass 19. The sliding rail cooperates with the pulley 33 to move the box 32 relative to the box cover 12 during pulling of the box cover 12, while the box 32 is fixed relative to the support plate 2.

[0068] On the basis of the above embodiment, the box body 32 can be set as a tubular structure with an opening only at one end, and the side wall of the box body 32 is provided with a first quick connector 24 for connecting to the air outlet pipe and a wire hole for passing the electrical circuit. The end of the box body 32 away from the opening is provided with a relay box, and a plurality of gas holes are evenly distributed on the end surface of the relay box. The gas holes can evenly and smoothly input the gas in the air inlet pipe into the box body 32. The relay box is provided with a second quick connector 25. The free end of the second quick connector 25 passes through the box body 32 and is connected to the air inlet pipe.

[0069] The box body 32 and the sealing cover 23 can be detachably connected. During use, when the box body 32 needs to be opened, the sealing cover 23 is directly removed, and when the box body 32 needs to be closed, the sealing cover 23 is installed. The sealing cover 23 can also be rotatably connected to the box body 32. When the box body 32 needs to be opened, the sealing cover 23 is directly flipped to the open position, and when the box body 32 needs to be closed, the sealing cover 23 is directly flipped to the closed position.

[0070] The functional box assembly 3 is connected to a sliding seat 13 on one side facing the box cover assembly. The sliding seat 13 is provided with a slide rail 16. The bottom of the box cover 12 is provided with a slide wheel 14 that cooperates with the slide rail 16. The length direction of the slide rail 16 is arranged along the axial direction of the box cover 12. Specifically, Figure 4 、 5 As shown, the sliding seat 13 is in the shape of a rectangular plate, one end of the sliding seat 13 is horizontally connected to the functional box assembly 3, and sliding rails are provided on both sides of the sliding seat 13. A sliding plate 15 is provided at the lower part of the box cover 12, and sliding wheels 14 that cooperate with the sliding rails are symmetrically installed on the lower surface of the sliding plate 15. The sliding plate 15 can be supported on the sliding rails through the sliding wheels 14 and slide along the sliding rails on the sliding seat 13.

[0071] Preferably, the sliding wheel 14 is a U-shaped pulley 33, and one end of the rotating shaft of the sliding wheel 14 is vertically fixed on the sliding plate 15. The number of sliding wheels 14 can be set to four. Of course, it can also be other required numbers, which are determined according to actual conditions.

[0072] like Figure 5 As shown, the box cover 12 is in an open state. When the box cover 12 is pushed toward the magnetic resonance imaging device circle 31, the sliding wheel 14 slides along the sliding track to open the box cover assembly. The box cover 12 is pushed toward the end cover 1 until the box cover 12 fits with the end cover 1, and the box cover 12 can be closed. Figure 5As shown, a locking plate 17 is fixedly connected to the sliding plate 15. The locking plate 17 is provided with a locking threaded hole. A locking bolt 18 is embedded in the locking threaded hole and cooperates with the locking threaded hole. When the sliding plate 15 needs to be locked relative to the sliding seat 13, one end of the locking bolt 18 is rotated so that the other end of the locking bolt 18 passes through the locking threaded hole and tightly presses against the slide rail 16. When the sliding plate 15 needs to be moved relative to the sliding seat 13, one end of the locking bolt 18 is simply rotated in the opposite direction to disengage the locking bolt 18 from the slide rail. Preferably, an anti-slip pad can be fixedly provided at one end of the locking bolt 18 to increase the friction between the locking bolt 18 and the slide rail.

[0073] The end cover 1 or the box cover 12 is provided with a lock 5. After the box cover 12 is tightly fitted with the end cover 1, the lock 5 can be fastened to lock the box cover 12 and the end cover 1, so that the inside of the box cover 12 is fully isolated from the outside to prevent external noise from being transmitted into the box cover 12. Preferably, a handle 20 can be provided on the box cover 12 to facilitate pushing the box cover 12.

[0074] like Figure 5 、 13 As shown, the radio frequency coil 26 can be set in the box 32, and the radio frequency coil 26 is a radio frequency coil specially adapted to the size of the baby, and is used to transmit and / or receive radio frequency signals for magnetic resonance scanning of the baby thereon. Two slide grooves 27 are evenly arranged on the radio frequency coil 26, and the bed board 29 with transfer can be set as an arc plate. The outer arc surface of the bed board 29 is provided with a sliding block 28, which can cooperate with the slide groove 27, and the bed board 29 is provided with a push-pull rod 30. During the transfer process, the slide groove 27 can be first cooperated with the baby incubator so that the sliding block 28 can be pushed into the slide groove 27, so that the bed board 29 can be pushed into the box 32.

[0075] It should be noted that due to the requirements of magnetic resonance examination, all components of the sealing device for magnetic resonance examination in this application document (including the box cover assembly, the sealing box assembly and the functional box assembly, etc.) must be made of non-metallic non-magnetic materials.

[0076] When the sealing device for magnetic resonance examination provided in this application document is used for magnetic resonance examination of infants, the dimensions of the radio frequency coil 26, the sealing box assembly, the box cover assembly and other structures can be set according to the size of the infant, and the specific use process is as follows:

[0077] First, it is necessary to provide the sealed box assembly with gas with constant temperature, humidity and oxygen content through the functional box assembly 3. Then, open the box cover 12, rotate the box body 32 to a position perpendicular to the length direction of the box cover 12, connect the sealed box to the infant incubator, open the sealing cover 23, and push the bed board 29 carrying the baby into the box body 32, cover the sealing cover 23, rotate the sealed box assembly to a position consistent with the length direction of the box cover 12, push the handle 20 to tightly fit the box cover 12 and the end cover 1 to seal, and buckle 5; start the conveyor belt on the magnetic resonance scanning bed 4 to send the entire box body 32 into the magnetic resonance imaging equipment for magnetic resonance scanning; after the magnetic resonance scanning is completed, start the conveyor belt on the magnetic resonance scanning bed 4 to send the entire box body 32 out of the magnetic resonance imaging equipment; open the box cover 12, rotate the box body 32 to a position perpendicular to the length direction of the box cover 12, connect the box body 32 to the infant incubator through the relay tube, open the sealing cover 23, and pull the bed board 29 carrying the baby out to the infant incubator. The entire examination process can achieve non-exposure and non-contact transfer of the baby, and the box cover assembly has a significant noise reduction effect, which can reduce or even avoid the use of sedatives. During the opening and closing of the box cover 12, the baby does not need to move with it, which greatly avoids secondary damage to the baby during the examination process.

[0078] The “first” and “second” in the first organic glass 6 and the second organic glass 19 , the first quick connector 24 and the second quick connector 25 , the first sound insulation and damping glue 34 and the second sound insulation and damping glue 35 mentioned in this application document are only for distinguishing the different positions and there is no order of precedence.
