Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a pad and a magnetic resonance imaging device for magnetic resonance examination. Background Technology

[0002] Currently, magnetic resonance imaging (MRI) scans typically take twenty minutes or longer. The patient lies on a hospital bed, and a headrest is usually placed under the patient's head to improve comfort.

[0003] During head scanning, the gradient coil vibrates due to the Lorentz force, generating significant noise. Therefore, patients typically wear noise-canceling headphones to reduce the amount of noise entering their ears during the scan. While the head needs to be fixed during a head scan, a pad is placed inside the head coil. However, this pad interferes with the noise-canceling headphones, making the use of the headphones less convenient and inconvenient. Utility Model Content

[0004] The purpose of this application is to provide a pad and a magnetic resonance imaging device for magnetic resonance examination, so as to solve the technical problem in the prior art that the operation is inconvenient due to the simultaneous use of noise-canceling headphones and the pad inside the head coil.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] The first aspect of this application provides a pad for magnetic resonance imaging (MRI) examination, comprising:

[0007] The main body of the cushion is used to support the patient's head. The main body of the cushion includes a support part and a movable part; the movable part is located inside the support part and has a certain elastic deformation capacity.

[0008] The noise-canceling headphones are mounted on the main body of the pad. When the head of the subject being scanned is supported on the main body of the pad, the movable part can be pushed towards the ear of the subject being scanned, and the noise-canceling headphones correspond to the ear of the subject's head.

[0009] In one implementation, the hardness of the support portion is greater than the hardness of the movable portion; wherein, a gas cavity is formed inside the movable portion to give the movable portion a certain elastic deformation capability.

[0010] In one implementation, the noise-canceling headphones are inserted into the body of the pad from the outer side of the movable part in the circumferential direction, the noise-canceling headphones are sealed to the movable part, and the noise-canceling headphones are fixed to the support part.

[0011] In one implementation, the inner circumferential side of the active part is U-shaped or C-shaped, and there are two noise-canceling headphones, with each of the two noise-canceling headphones located near the corresponding end of the active part.

[0012] In one implementation, the mat body also includes a noise reduction section, which is disposed on the outer peripheral side of the movable section.

[0013] In one implementation, the noise reduction part is made of noise reduction and sound filtering material.

[0014] In one implementation, the support portion of the pad body is located on the outer peripheral side of the noise reduction portion, and the noise-canceling headphones pass through the noise reduction portion along the direction from the inner peripheral side to the outer peripheral side.

[0015] In one implementation, along the direction from the support to the moving part, the thickness of the support is less than the thickness of the moving part and less than the thickness of the noise reduction part.

[0016] In one implementation, the support portion is bonded to the noise reduction portion, and / or the movable portion is bonded to the noise reduction portion.

[0017] A second aspect of this application provides a magnetic resonance imaging (MRI) device, including a device body and a pad for MRI examination as described in any of the above embodiments, wherein noise-canceling headphones for the pad for MRI examination are connected to the device body via an air duct.

[0018] The beneficial effects of this application are as follows: In this embodiment, by placing the noise-canceling headphones on the main body of the pad, the step of the scanned object wearing headphones can be reduced during head scanning, thereby avoiding the technical problem of inconvenience caused by using noise-canceling headphones and pads inside the head coil at the same time in the prior art; This embodiment integrates the noise-canceling headphones and the main body of the pad together, optimizes the workflow, and improves scanning efficiency.

[0033] Please see Figure 1 This embodiment provides a pad 100 for magnetic resonance imaging examination, including a pad body 1 and noise-canceling headphones 2.

[0034] The cushion body 1 is used to support the head of the subject being scanned. For example, during an MRI scan (except for head scans), the subject lies on a hospital bed, and their head can be supported by the cushion body 1. When scanning the head, the cushion body 1, in conjunction with the head coil, fixes the subject's head in place.

[0035] The main body of the mat 1 includes a movable part 11 and a support part 13, please refer to Figure 1 The diagram illustrates the movable part 11 and the support part 13, with the movable part 11 located inside the support part 13.

[0036] The movable part 11 has a certain elastic deformation capacity, while the support part 13 has a certain support capacity. When the head of the scanned object is supported on the movable part 11, the comfort can be improved.

[0037] Please see Figure 1 The noise-canceling headphones 2 are mounted on the pad body 1. When the head of the object being scanned is supported on the pad body 1, the movable part 11 can be pushed towards the ear of the object being scanned, and the noise-canceling headphones 2 correspond to the ear of the object being scanned.

[0038] The noise-canceling headphones 2 are magnetic resonance headphones. During head scanning, the pad body 1 will work with the head coil. Since the noise-canceling headphones 2 are set on the pad body 1, the step of the scanned object wearing headphones is reduced.

[0039] The movable part 11 can squeeze towards the ear of the scanning object. This means that when the head corresponding to the scanning is supported on the movable part 11, since the movable part 11 has a certain elastic deformation capability, the movable part 11 can squeeze the ear of the scanning object while undergoing elastic deformation, thus blocking the ear of the scanning object.

[0040] The noise-canceling headphones 2 correspond to the ears of the subject's head. This means that when the subject's head is supported on the pad body 1, the noise-canceling headphones 2 are close to the subject's ears. Since the movable part 11 can be pushed towards the subject's ears and the noise-canceling headphones 2 are close to the subject's ears, the effect of wearing noise-canceling headphones 2 can be achieved. At this time, when performing head scanning, the noise-canceling headphones 2 can reduce the amount of noise entering the ears, and the subject can receive instructions from the technician through the noise-canceling headphones 2.

[0041] In one specific example, the noise-canceling headphones 2 are air-conducting headphones. The noise-canceling headphones 2 are connected to the MRI scanning equipment through an air duct, and use air vibration to generate sound waves that are transmitted to the ear of the scanned object.

[0042] In one example, two noise-canceling headphones 2 are symmetrically arranged on the pad body 1. When the head of the object being scanned is supported on the pad body 1, the noise-canceling headphones 2 are positioned close to the corresponding ear of the object being scanned. In other examples, one noise-canceling headphone 2 may also be used.

[0043] In one example, the noise-canceling headphones 2 are fixed to the pad body 1.

[0044] In another example, the noise-canceling headphones 2 are movably connected to the pad body 1. For example, when using the pad 100 for magnetic resonance imaging, the noise-canceling headphones 2 can be adjusted first to facilitate the head of the scanned object to be supported on the pad body 1, and then the noise-canceling headphones 2 can be adjusted so that the noise-canceling headphones 2 move closer to the ear of the scanned object.

[0045] In this embodiment, by placing the noise-canceling headphones 2 on the pad body 1, the step of the scanned object wearing headphones can be reduced during head scanning, thereby avoiding the technical problem in the prior art where it is inconvenient to operate due to wearing noise-canceling headphones and placing a pad inside the head coil at the same time. This embodiment integrates the noise-canceling headphones 2 and the pad body 1 together, optimizing the workflow and improving scanning efficiency.

[0046] Regarding the movable part 11, it possesses a certain elastic deformation capability. For example, in one embodiment, a gas cavity is formed inside the movable part 11, meaning the movable part 11 is filled with gas. When the head of the scanned object is supported on the pad body 1, the movable part 11 can undergo a certain elastic deformation to improve the comfort of the scanned object's head supported on the pad body 1. The movable part 11 can be understood as a gas cavity that can be filled with gas, enclosed by a membrane. In one embodiment, the membrane material of the movable part 11 is an elastic material.

[0047] When a gas chamber is formed inside the movable part 11, in one example, the movable part 11 is a completely closed structure; in another example, a switch valve is provided on the movable part 11. When the switch valve is opened, gas can be introduced into the movable part 11, and when the switch valve is closed, the gas inside the movable part 11 is sealed inside the movable part 11. In a specific example, the switch valve on the movable part 11 can be located at the free end of the movable part 11.

[0048] Regarding the movable part 11 having a certain elastic deformation capability, for example, in another embodiment, the movable part 11 is made of a porous sponge.

[0049] In this embodiment, by setting the movable part 11 as an elastic structure, the movable part 11 has a certain elastic deformation capability, which can improve the comfort of the head of the scanned object lying on the main body of the mat 1, and can adapt to different scanned objects.

[0050] In one embodiment, the noise-canceling headphones 2 are concealed within the pad 100 for magnetic resonance imaging (MRI) examination; in another embodiment, some or all of the noise-canceling headphones 2 are exposed outside the pad 100 for MRI examination.

[0051] Regarding the noise-canceling headphones 2 being concealed within the pad 100 used for magnetic resonance imaging (MRI) examination, it should be noted that the noise-canceling headphones 2 are connected to the MRI scan via an air conduit. In this embodiment, the air conduit is not part of the noise-canceling headphones 2.

[0052] In one embodiment, the air duct is detachably connected to the noise-canceling headphones 2; in another example, the air duct and the noise-canceling headphones 2 are not detachably connected.

[0053] Regarding the support portion 13, in one embodiment, the hardness of the support portion 13 is greater than that of the movable portion 11, so that the support portion 13 has a certain supporting capacity.

[0054] In one specific example, the rigidity of the support part 13 is greater than that of the movable part 11, and a gas cavity is formed inside the movable part 11, so the noise-canceling headphones 2 are not inserted into the movable part 11.

[0055] In another specific example, the rigidity of the support part 13 is greater than that of the movable part 11, and a gas cavity is formed inside the movable part 11. The noise-canceling headphones 2 are inserted into the pad body 1 from the outer side of the movable part 11 in the circumferential direction, and the noise-canceling headphones 2 are sealed with the movable part 11.

[0056] Due to the deformation of the gas chamber of the movable part 11 and the sufficient rigidity of the support part 13, when the scanned object lies down, the head is supported by the support part 13 while the gas chamber can also compress and fix the head. Under the compression of the gas chamber, the movable part 11 is made closer to the ear.

[0057] Please see Figure 1 The noise-canceling headphones 2 are inserted into the pad body 1 from the outer side of the movable part 11 in the circumferential direction, and the noise-canceling headphones 2 are sealed to the movable part 11 to prevent the gas inside the movable part 11 from leaking through the connection between the noise-canceling headphones 2 and the movable part 11.

[0058] Furthermore, the noise-canceling headphones 2 do not extend beyond the inner side of the movable part 11 in the circumferential direction. Since the interior of the movable part 11 forms a gas cavity, even though the noise-canceling headphones 2 are separated from the ear of the scanned subject by the diaphragm of the movable part 11 during use, it does not affect the noise-canceling headphones 2 from reducing the amount of noise entering the ear of the scanned subject, and it does not affect the scanned subject from receiving the technician's instructions through the noise-canceling headphones 2.

[0059] In this embodiment, the noise-canceling headphones 2 are inserted into the pad body 1 from the outer side of the movable part 11 in the circumferential direction, so as to avoid the noise-canceling headphones 2 affecting the head support of the scanned object on the pad body 1.

[0060] In one embodiment, please refer to Figure 1 The inner circumferential side 111 of the active part 11 is U-shaped or C-shaped, and the two noise-canceling headphones 2 are respectively close to the ends of the corresponding sides of the active part 11.

[0061] Please see Figure 1 This illustrates the inner circumferential side 111 of the active part 11, which can be understood as... Figure 1 The inner circumferential side 111 shown is C-shaped, when in Figure 1 Based on this, the length of the movable part 11 in the vertical direction is further increased, which can be understood as the inner circumference side 111 being U-shaped.

[0062] In one example, the active part 11 is shaped like a U or a C.

[0063] Along the circumferential direction of the movable part 11, the movable part 11 includes a middle region segment and an end region segment. The two end region segments are respectively connected to the middle region segment, and the two noise-canceling headphones 2 are respectively located in the end region segments. When the head of the scanned object lies on the movable part 11, the back of the scanned object's head presses against the middle region segment, and the end region segment is located on one side of the scanned object's ear.

[0064] In one scenario, a gas cavity is formed inside the movable part 11. Noise-canceling headphones 2 are inserted into the pad body 1 from the outer circumferential side of the movable part 11. The inner circumferential side 111 of the movable part 11 is C-shaped, with the two noise-canceling headphones 2 positioned near the corresponding ends of the movable part 11. When the head of the subject being scanned is supported on the middle section of the movable part 11, the thickness of the middle section decreases, and air flows from the middle section to the two end sections of the movable part 11. This causes the two end sections of the movable part 11 to press against the ears of the subject being scanned. The noise-canceling headphones 2 correspond to the ears of the subject's head, thus achieving the effect of wearing noise-canceling headphones 2. Furthermore, because the air flow from the middle section of the movable part 11 to the two end sections of the movable part 11 presses against the ears of the subject, the pad 100 used for magnetic resonance imaging, in conjunction with the inner shell of the head coil, effectively secures the head of the subject being scanned.

[0065] In this embodiment, by setting the inner circumferential side 111 of the movable part 11 to be U-shaped or C-shaped and the two noise-canceling headphones 2 to be close to the ends of the corresponding sides of the movable part 11, it is convenient for the scanned object to use the pad 100 for magnetic resonance examination.

[0066] In one embodiment, please refer to Figure 1 The mat body 1 also includes a noise reduction part 12, which is disposed on the outer peripheral side of the movable part 11 and is used to reduce noise in the environment.

[0067] In one example, the noise reduction part 12 is disposed on the outer peripheral side of the support part 13, and the support part 13 is disposed on the outer peripheral side of the movable part 11.

[0068] When the noise-canceling headphones 2 are embedded in the movable part 11 and the noise reduction part 12 is disposed between the movable part 11 and the support part 13, the noise-canceling headphones 2 pass through the noise reduction part 12 in the direction from the inner periphery to the side to the outer periphery to the side.

[0069] In one example, the noise reduction unit 12 is generally U-shaped or C-shaped.

[0070] In one example, the two ends of the noise reduction section 12 are flush with the corresponding ends of the active section 11.

[0071] In one example, the thickness of the noise reduction portion 12 is no greater than the thickness of the movable portion 11 in the direction from the inner side of the pad 100 for magnetic resonance imaging to the outer side of the pad 100 for magnetic resonance imaging.

[0072] In one example, the side of the back of the head of the subject being scanned supported by the pad 100 for magnetic resonance imaging is referred to as the upper side. Along the direction from the upper side to the lower side of the pad 100 for magnetic resonance imaging, the height of the noise reduction part 12 is equal to the height of the movable part 11, and the upper side of the noise reduction part 12 is flush with the upper side of the movable part 11, and the lower side of the noise reduction part 12 is flush with the lower side of the movable part 11.

[0073] In one example, the number of noise reduction sections 12 is more than one in the direction from the inner side of the pad 100 for magnetic resonance examination to the outer side of the pad 100 for magnetic resonance examination.

[0074] When there are two or more noise reduction parts 12, the materials of each layer of noise reduction parts 12 are the same, or the materials of each layer of noise reduction parts 12 are different.

[0075] In this embodiment, the pad body 1 is further provided with a noise reduction part 12, which is used to reduce noise in the noise environment and reduce the impact of noise generated by the gradient coil on the scanned object.

[0076] In one embodiment, the noise reduction part 12 is made of noise reduction and sound filtering material, which refers to a material that can effectively reduce noise and filter sound.

[0077] For example, in one specific example, the sound filter layer uses a sound-absorbing material with a sound absorption coefficient greater than 0.2.

[0078] In one embodiment, please refer to Figure 1 The support part 13 of the main body of the pad is located on the outer peripheral side of the noise reduction part 12, that is, the noise reduction part 12 is located between the support part 13 and the movable part 11, and the noise-canceling headphones 2 are fixed on the support part 13. The hardness of the support part 13 is greater than that of the movable part 11.

[0079] The support portion 13 serves as both a protective noise-reducing portion 12 and a movable portion 11. Furthermore, the relatively high rigidity of the support portion 13 facilitates the compression and deformation of the two end portions of the movable portion 11 towards the ear of the scanned object when the head of the object is supported on the middle section of the pad body 1. Additionally, the greater rigidity of the support portion 13 compared to the movable portion 11 makes it easier to secure the noise-canceling headphones 2 to the support portion 13.

[0080] When the noise reduction part 12 is disposed between the support part 13 and the movable part 11, regarding the position of the noise-canceling headphones 2 and the support part 13, in one example, the noise-canceling headphones 2 pass through the support part 13 in a direction from the inner periphery to the side to the outer periphery to the side.

[0081] When the noise reduction part 12 is disposed between the support part 13 and the movable part 11, regarding the position of the noise-canceling headphones 2 and the support part 13, in another example, the support part 13 is provided with a jack along the direction from the inner periphery to the side to the outer periphery to the side, and one end of the noise-canceling headphones 2 is located in the jack and the noise-canceling headphones 2 does not extend out of the support part 13 along the direction from the inner periphery to the side to the outer periphery to the side.

[0082] In one example, the support portion 13 is attached to the outer peripheral side of the noise reduction portion 12.

[0083] In one example, the noise reduction part 12 is attached to the outer peripheral side of the active part 11.

[0084] In one example, the support portion 13 is integrally U-shaped or C-shaped.

[0085] In one example, the pad 100 used for magnetic resonance imaging is U-shaped or C-shaped.

[0086] In one example, the two ends of the support portion 13 are flush with the ends of the noise reduction portion 12 on the corresponding sides.

[0087] In one example, the side of the back of the head of the subject being scanned by the pad 100 used for magnetic resonance imaging is referred to as the upper side. Along the direction from the upper side to the lower side of the pad 100 used for magnetic resonance imaging, the height of the support part 13 is equal to the height of the noise reduction part 12, and the upper side of the support part 13 is flush with the upper side of the noise reduction part 12, and the lower side of the support part 13 is flush with the lower side of the noise reduction part 12.

[0088] In one embodiment, along the direction from the support portion 13 to the movable portion 11, the thickness of the support portion 13 is less than the thickness of the movable portion 11 and less than the thickness of the noise reduction portion 12.

[0089] In this embodiment, by setting the thickness of the support part 13 to be less than the thickness of the movable part 11 and less than the thickness of the noise reduction part 12, the thickness of the movable part 11 is increased as much as possible while ensuring that the support part 13 plays a supporting role, so as to improve the comfort of the head of the scanned object being supported on the pad body 1, and the thickness of the noise reduction part 12 is increased as much as possible to reduce the impact of the noise generated by the gradient coil on the scanned object.

[0090] This embodiment provides a magnetic resonance imaging (MRI) device, including a device body and a pad 100 for MRI examination provided in any of the above embodiments. The noise-canceling headphones 2 of the pad 100 for MRI examination are connected to the device body through an air duct.

[0091] The specific structure of the pad 100 used for magnetic resonance imaging has been described above and will not be repeated here.

[0092] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
