Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a magnetic resonance simulation device. Background Art

[0002] Magnetic resonance imaging (MRI) is a diagnostic technology that utilizes the magnetic resonance of human tissue with specific atomic nuclei. It uses a computer to process radiofrequency detection signals and reconstruct images of specific layers of the human body. MRI requires the patient to remain as still as possible while being scanned for extended periods of time within a volumetric CT coil (VTC).

[0003] However, during an MRI scan, the volume coil barrel creates a confined, uncomfortable environment. Due to unfamiliarity with the MRI environment, some patients may experience significant body movement during the scan, compromising the quality of the MRI data. Some patients also experience anxiety, leading to premature termination of the scan and resulting in wasted resources.

[0004] Magnetic resonance simulation equipment can simulate the magnetic resonance scanning environment, allowing patients to conduct simulation training before the MRI scan, adapt to the environment in advance, relieve patients' anxiety during the MRI scan, and ensure that the MRI scan can proceed smoothly.

[0005] When current passes through the volume coil, it vibrates to varying degrees. The volume coil vibrates with varying intensities depending on the magnitude of the current. Traditional MRI simulators can simulate the noise and vibrations experienced during an MRI scan. However, the vibrations experienced by patients in traditional simulations are generally weaker than those experienced in real-world conditions. This can lead to patients experiencing discomfort during actual MRI scans due to the noticeable vibrations. Increasing the power input to the vibration simulator to enhance the patient's sense of vibration results in a significant loss of vibration energy during mechanical transmission. Utility Model Content

[0006] Based on this, the present invention provides a magnetic resonance simulation device that can solve or at least alleviate the above technical problems.

[0007] The utility model provides a magnetic resonance simulation device, comprising:

[0008] base;

[0009] A cavity cover is mounted on the base; the cavity cover encloses a simulated magnet cavity;

[0010] a bed plate slidably connected to the base; the bed plate has a first position and a second position relative to the cavity cover; the bed plate is more accommodated in the simulated magnet cavity in the first position than in the second position;

[0011] A vibration member is connected to the bottom side of the bed board and is used to transmit vibration to the bed board.

[0012] In the above-mentioned magnetic resonance simulation equipment, the cavity cover is installed above the base. A certain space is formed by utilizing the inner wall surface of the cavity cover, and this space serves as a simulated magnet cavity. The size and shape of the space inside the simulated magnet cavity are close to the spatial environment during the actual magnetic resonance scanning process, so that the experiencer can adapt to the actual magnetic resonance scanning environment in advance. The bed board is connected to the base by sliding, so that the experiencer can enter and exit the simulated magnet cavity. When the bed board is in the first position, the experiencer lying on the bed board can be completely inside the simulated magnet cavity. When the bed board is in the second position, the bed board can be completely outside the simulated magnet cavity, making it convenient for the experiencer to enter and exit the simulated magnet cavity. Because the vibrating element is connected to the bottom side of the bed board and transmits vibration to the bed board, the bed board can have a certain vibration amplitude. When the experiencer lies on the bed board, he can feel the vibration of the bed board, thereby experiencing the actual magnetic resonance scanning environment more realistically, which is conducive to the experiencer feeling the vibration of the volume coil. Since the vibrator is connected to the bottom side of the bed board, the vibration energy of the vibrator can be transmitted to the bed board along a shorter path, effectively reducing the consumption of vibration energy during the transmission process, and helping the experiencer to experience a stronger vibration feeling, which helps to improve the simulation effect of the magnetic resonance simulation equipment.

[0013] In one embodiment, a plurality of the vibration members are arranged in an array and spaced apart on the bottom side of the bed board.

[0014] In one embodiment, a groove is provided on the bottom side of the bed board; the opening of the groove faces the base; and the vibrating member is fixedly disposed in the groove.

[0015] In one embodiment, the outer peripheral surface of the vibration member is interference-fitted with the inner wall surface of the groove.

[0016] In one embodiment, it further includes a bottom plate connected to the bottom side of the bed board; the bottom plate covers the opening of the groove; and the bottom plate is fixedly connected to the vibrating member.

[0017] In one embodiment, a noise simulation component is further included; the noise simulation component is connected to the cavity cover.

[0018] In one embodiment, it further includes an audio driving module and a vibration driving module; the audio driving module is electrically connected to the noise simulation component and the vibration driving module respectively; and the vibration driving module is electrically connected to the vibration component.

[0019] In one embodiment, the magnetic resonance simulation device includes at least two noise simulation components; and the two sides of the cavity cover are respectively connected to the noise simulation components.

[0020] In one embodiment, the distance between the bed board and the bottom support point of the base is no more than 50 cm.

[0021] In one embodiment, the outer surface of the cavity cover is exposed. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of this application, not all of them.

For example, they may refer to fixed connections, detachable connections, integrated connections, mechanical connections, electrical connections, direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0033] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0034] This application provides a magnetic resonance simulation device 100. This device can be used to provide a user with an experience environment that closely resembles an actual magnetic resonance scanning environment. While inside the device 100, the user experiences a certain vibration sensation. This vibration allows the user to experience the vibrations caused by the volume coil in an actual magnetic resonance scanning environment.

[0035] Combine Figure 1 、 Figure 4 and Figure 5 As shown, a magnetic resonance simulation device 100 includes a base 20, a cavity cover 30, a bed plate 40, and a vibrator 50. The cavity cover 30 is mounted on the base 20. The cavity cover 30 encloses a simulated magnet cavity 31. The bed plate 40 is slidably connected to the base 20. The bed plate 40 has a first position and a second position relative to the cavity cover 30. In the first position, the bed plate 40 is more fully accommodated within the simulated magnet cavity 31 than in the second position. The vibrator 50 is connected to the bottom side of the bed plate 40 and is used to transmit vibration to the bed plate 40.

[0036] Specifically, the chamber cover 30 is mounted above the base 20. The inner wall of the chamber cover 30 forms a space that serves as the simulated magnet chamber 31. The size and shape of the simulated magnet chamber 31 closely resemble the spatial environment during an actual MRI scan, allowing the user to acclimate to the actual MRI scanning environment in advance. The bed plate 40 is slidably connected to the base 20, allowing the user to enter and exit the simulated magnet chamber 31. When the bed plate 40 is in the first position, the user lying on it can be completely inside the simulated magnet chamber 31. When the bed plate 40 is in the second position, the bed plate 40 can be completely outside the simulated magnet chamber 31, facilitating the user's entry and exit. Because the vibrator 50 is connected to the bottom side of the bed plate 40 and transmits vibration to it, the bed plate 40 has a certain vibration amplitude. When the user lies on the bed plate 40, they can feel its vibration, providing a more realistic experience of the actual MRI scanning environment and helping them perceive the vibration of the volume coil. Since the vibrating member 50 is connected to the bottom side of the bed board 40 , the vibration energy of the vibrating member 50 can be transmitted to the bed board 40 along a shorter path, effectively reducing the consumption of vibration energy during the transmission process, and helping the user to experience a stronger vibration sensation, thereby helping to improve the simulation effect of the magnetic resonance simulation device 100 .

[0037] In some embodiments, combined Figure 3 and Figure 4 As shown, the shape of the cavity cover 30 is close to cylindrical. More specifically, the cavity cover 30 is a partial cylindrical structure. Both ends of the cavity cover 30 are open, and one end is used for the bed plate 40 to enter and exit the simulated magnet cavity 31.

[0038] In some embodiments, combined Figure 1 As shown, the outer surface of the cavity cover 30 is exposed. Since the outer surface of the cavity cover 30 is not covered by other structures, the volume of the magnetic resonance simulation device 100 can be controlled, effectively reducing the indoor space occupied by the magnetic resonance simulation device 100.

[0039] In some embodiments, combined Figure 5 and Figure 6 As shown, a groove 41 is provided on the bottom side of the bed board 40. The opening of the groove 41 faces the base 20. The vibrating member 50 is fixedly arranged in the groove 41. Specifically, the vibrating member 50 is placed into the groove 41 from the opening of the groove 41. Since the opening of the groove 41 faces the base 20, the upper surface of the bed board 40 can be kept flat. The depth and width of the groove 41 correspond to the size of the vibrating member 50, respectively. When the vibrating member 50 is installed in the groove 41, it is possible to avoid the vibrating member 50 protruding out of the surface of the bottom side of the bed board 40, or reduce the degree to which the vibrating member 50 protrudes out of the surface of the bottom side of the bed board 40, thereby helping to improve the compactness of the connection between the bed board 40 and the vibrating member 50, and reducing the possibility of interference and obstruction of the bed board 40 during movement.

[0040] In some embodiments, combined Figure 6 As shown, the outer circumference of the vibrating member 50 is interference fit with the inner wall of the groove 41. Specifically, the inner wall of the groove 41 is arranged around the bottom of the groove 41. The bottom of the groove 41 faces the base 20. Since the outer circumference of the vibrating member 50 is interference fit with the inner wall of the groove 41, the inner wall of the groove 41 can generate pressure on the vibrating member 50 from different circumferential angles, so that there is greater friction between the vibrating member 50 and the inner wall of the groove 41, so that the vibrating member 50 can be stably maintained in the groove 41. At the same time, the outer circumference of the vibrating member 50 and the inner wall of the groove 41 maintain sufficient contact, so that the vibration of the vibrating member 50 can be more fully transmitted to the bed board 40, effectively reducing the vibration energy transmission loss between the vibrating member 50 and the bed board 40.

[0041] In some embodiments, combined Figure 5 As shown, the interior space of the groove 41 includes a first receiving area 411 and a second receiving area 412. The first receiving area 411 is used to accommodate the main body of the vibrator 50, and the second receiving area 412 is used to accommodate the terminals of the vibrator 50. In some embodiments, the space of the first receiving area 411 is cylindrical, and the space of the second receiving area 412 is rectangular.

[0042] In some embodiments, combined Figure 4 and Figure 5 As shown, the magnetic resonance simulation device 100 also includes a bottom plate 51 connected to the bottom side of the bed plate 40. The bottom plate 51 covers the opening of the groove 41. The bottom plate 51 is fixedly connected to the vibrator 50. Specifically, because the bottom plate 51 is fixedly connected to the bottom side of the bed plate 40 and the vibrator 50, respectively, the vibrator 50 can transmit vibrations to the bed plate 40 through the bottom plate 51. At the same time, because the bottom plate 51 covers the opening of the groove 41, it can prevent the vibrator 50 from falling out of the groove 41, thereby preventing the vibrator 50 from falling onto the base 20 and affecting the relative sliding between the bed plate 40 and the base 20. In some embodiments, the bottom plate 51 is a circuit board, and the bottom plate 51 is also electrically connected to the vibrator 50. The conductive portion of the bottom plate 51 can transmit electrical energy and control signals to the vibrator 50. Furthermore, the vibrator 50 is welded and fixed to the bottom plate 51.

[0043] In some embodiments, the bottom plate 51 is fixedly connected to the surface of the bottom side of the bed board 40. More specifically, the bottom plate 51 is fixedly connected to the bottom side of the bed board 40 by screws or other fasteners.

[0044] In some other embodiments, without considering that the vibration member 50 protrudes from the bottom surface of the bed board 40 , the vibration member 50 may be positioned and connected to the bottom surface of the bed board 40 .

[0045] In some embodiments, the distance between the bed board 40 and the bottom support point of the base 20 is no greater than 50 cm. This reduces the height of the top surface of the bed board 40 relative to the ground, effectively minimizing injuries to the user if they accidentally fall from the bed board 40. In some embodiments, the lower edge of the base 20 directly contacts the ground, serving as the bottom support point of the base 20. In other embodiments, the bottom of the base 20 is provided with legs, the lower ends of which are designed to contact the ground. The lower ends of the legs serve as the bottom support points of the base 20.

[0046] In some embodiments, combined Figure 3 and Figure 4 As shown, one of the base 20 and the bed board 40 is provided with a slide groove 21, and the other is connected to a pulley 42. The pulley 42 is partially accommodated in the slide groove 21. The axial direction of the pulley 42 is perpendicular to the length direction of the slide groove 21. The pulley 42 is arranged to abut against the bottom surface of the slide groove 21, so that the bed board 40 can slide relative to the base 20. In some embodiments, two slide grooves 21 are provided on the upper surface of the base 20. The two slide grooves 21 are parallel and spaced apart. Furthermore, the slide groove 21 is arranged close to the side edge of the upper surface of the base 20. The bed board 40 is connected to a plurality of pulleys 42, and the plurality of pulleys 42 are distributed along a length direction parallel to the slide groove 21. Specifically, the slide groove 21 extends from the inside of the simulated magnet cavity 31 to the outside of the simulated magnet cavity 31, so that the range of movement of the bed board 40 can reach the inside of the simulated magnet cavity 31.

[0047] In some embodiments, combined Figure 5 As shown, a plurality of vibrating members 50 are arranged in an array at intervals on the bottom side of the bed board 40. Specifically, a plurality of vibrating members 50 may be arranged in a row. At the same time, a plurality of rows of vibrating members 50 are distributed linearly. Adjacent vibrating members 50 are arranged at intervals, so that a plurality of vibrating members 50 can transmit vibrations to the bed board 40 at different positions on the bottom side of the bed board 40, so that a larger area on the bed board 40 can transmit vibrations to the user. In other embodiments, a plurality of vibrating members 50 may be distributed at intervals along the circumference. A plurality of concentric circles are respectively provided with a plurality of vibrating members 50.

[0048] In some embodiments, the vibrator 50 is a linear vibration motor. Further, the vibrator 50 is a Z-axis linear vibration motor.

[0049] In some embodiments, combined Figure 1 and Figure 4As shown, the magnetic resonance simulation device 100 also includes a noise simulation component 60. The noise simulation component 60 is connected to the cavity cover 30. Specifically, during an actual magnetic resonance scanning process, the operation of various devices around the patient will generate a certain amount of noise. The noise simulation component 60 is used to emit simulated noise, and the simulated noise is close to the sound that the patient can hear during an actual magnetic resonance scanning process. Since the noise simulation component 60 is connected to the cavity cover 30, the simulated noise can be transmitted to the experiencer along a shorter path, allowing the experiencer to hear the simulated noise more clearly. In some embodiments, the noise simulation component 60 is a speaker.

[0050] In some embodiments, combined Figure 1 and Figure 2 As shown, the magnetic resonance simulator 100 includes at least two noise simulators 60. A noise simulator 60 is connected to each side of the cavity cover 30. Because each noise simulator 60 is connected to each side of the cavity cover 30, each noise simulator 60 independently generates simulated noise, making the simulated noise heard by the user more three-dimensional. Specifically, the relative direction between the two sides of the cavity cover 30 is perpendicular to the sliding direction of the bed board 40.

[0051] Further, combined with Figure 1 As shown, the noise simulation member 60 is disposed outside the cavity cover 30, preventing the noise simulation member 60 from occupying the internal space of the simulated magnet cavity 31. More specifically, the cavity cover 30 is provided with a sound-transmitting hole 32, the position of which corresponds to the noise simulation member 60.

[0052] In some embodiments, combined Figure 7 As shown, the magnetic resonance simulation device 100 also includes an audio driving module 70 and a vibration driving module 80. The audio driving module 70 is electrically connected to the noise simulation component 60 and the vibration driving module 80, respectively. The vibration driving module 80 is electrically connected to the vibration component 50. Specifically, the audio driving module 70 is used to output an audio signal to the noise simulation component 60. The noise simulation component 60 can directly amplify the audio signal and generate simulated noise. The noise simulation component 60 can also first convert the digital audio signal into an analog signal form, and then amplify the signal and generate simulated noise.

[0053] During the actual magnetic resonance scanning process, affected by the operating status of various devices around the patient, the patient will generally feel greater vibration when the noise is louder or the frequency is higher. Since the audio drive module 70 is electrically connected to the vibration drive module 80, the audio drive module 70 transmits an audio signal to the vibration drive module 80, and the vibration drive module 80 adjusts the vibration amplitude and vibration frequency of the vibration member 50 according to the audio amplitude information and audio frequency information in the audio signal, so that the vibration state of the vibration member 50 is correlated with the simulated noise, thereby allowing the user to experience the actual magnetic resonance scanning process more realistically. Specifically, the vibration drive module 80 transmits electrical energy to the vibration member 50.

[0054] In some other embodiments, the vibration driving module 80 may change the vibration amplitude of the vibration member 50 synchronously with the audio amplitude information in the audio signal. The vibration driving module 80 may change the vibration frequency of the vibration member 50 synchronously with the audio frequency information in the audio signal.

[0055] In some embodiments, the vibration driving module 80 is disposed on the bottom plate 51. Specifically, the bottom plate 51 is a circuit board, and the vibration driving module 80 is electrically connected to the vibration element through the bottom plate 51.

[0056] In some embodiments, combined Figure 1 As shown, the magnetic resonance simulation device 100 can also be provided with one or more of a lighting component, a ventilation system, a cross positioning light, a head coil 43 and a head coil reflector as needed. Among them, the lighting component is used to provide lighting in the simulated magnet cavity 31. Specifically, the lighting component is a lighting light bar. The ventilation system is used to maintain the flow of air in the simulated magnet cavity 31 to avoid the decrease of the oxygen concentration in the simulated magnet cavity 31. The provision of a cross positioning light, a head coil 43 or a head coil reflector can make the device layout in the simulated magnet cavity 31 closer to the actual magnetic resonance scanning environment, further improving the simulation effect of the magnetic resonance simulation device 100.

[0057] The above embodiments are merely descriptions of the preferred embodiments of the present application and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solutions of the present application by ordinary engineering and technical personnel in this field should fall within the scope of protection determined by the claims of the present application.
