[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0037] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0038] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0039] In order to solve the problem of poor dustproof effect of nuclear magnetic resonance equipment in the prior art, the present invention provides a protective device for nuclear magnetic resonance equipment and a nuclear magnetic resonance equipment. Among them, the nuclear magnetic resonance equipment described below includes the protective device for nuclear magnetic resonance equipment described below.

[0040] like Figures 3 to 5 As shown, the protective device for a nuclear magnetic resonance device includes a protective cover 10, a transmission wire 20, a fitting 30 and an elastic reset member 40. The protective cover 10 is adjustably arranged on the socket 80 of the nuclear magnetic resonance device. The protective cover 10 has a first position for avoiding the electrical connection hole 83 of the socket 80 and a second position for blocking the electrical connection hole 83 of the socket 80. The first end of the transmission wire 20 is connected to the protective cover 10. The second end of the transmission wire 20 is connected to the fitting 30. In response to the coil 70 of the nuclear magnetic resonance device being inserted into the electrical connection hole 83, the fitting 30 is squeezed by the coil 70 and moves along the insertion direction of the coil 70, so as to drive the protective cover 10 to move from the second position to the first position through the transmission wire 20. The elastic reset member 40 is used to provide a reset force for the protective cover 10 to return from the first position to the second position.

[0041] Through the above arrangement, the fitting 30 is connected to the protective cover 10 via the transmission wire 20, so that when the coil 70 of the MRI device is inserted into the electrical connection hole 83 of the socket 80, the fitting 30 can be pressed to move along the insertion direction of the coil 70, thereby driving the protective cover 10 to open via the transmission wire 20, so that the coil 70 and the socket 80 can be plugged together. When the coil 70 is removed from the socket 80, the reset force of the elastic reset member 40 can automatically restore the protective cover 10 to a state that covers the electrical connection hole 83 of the socket 80. This allows the electrical connection hole 83 to be automatically opened and closed without manual operation, saving operation steps and time, while preventing the user from forgetting to close the protective cover 10, and greatly improving the dustproof effect of the MRI device. In addition, the use of the transmission wire 20 can also prevent the protective device from introducing magnetic components, thereby avoiding any impact on the MRI device.

[0042] Specifically, such as Figures 3 to 7 As shown, the socket 80 includes a fixing base 82, one side of the top surface of which has an electrical connection hole 83. The protective cover 10 is horizontally and movably disposed on the top surface of the fixing base 82. When the protective cover 10 needs to be opened, the protective cover 10 moves to the other side of the top surface of the fixing base 82. Other components of the protective device are located around the fixing base 82.

[0043] In this embodiment, the coil 70 is inserted in a vertical direction.

[0044] In this embodiment, the elastic return member 40 is a spring.

[0045] It is understood that the transmission wire 20 acts as a force transmitter, enabling the protective cover 10 to move horizontally under the vertical compression of the coil 70. When the mating member 30 is located to one side of the protective cover 10 in the direction of movement, the transmission wire 20 can directly connect with the mating member 30 and the protective cover 10 without the need for an intermediate component. However, for the socket 80, the protective cover 10 moves horizontally along its length. This arrangement would result in the socket 80 being relatively long, and the width of the socket 80 would not be properly utilized, resulting in wasted space.

[0046] To improve the space utilization of the socket 80, in this embodiment, the protective device further includes a reversing assembly, which is slidably connected to the drive wire 20 and is used to position the mating member 30 at a predetermined position. Specifically, the predetermined position is located on the side of the socket 80 along the width direction. By changing the direction of the drive wire 20 by the reversing assembly, the socket 80 does not need to be long.

[0047] In this embodiment, if Figures 3 to 5 As shown, the reversing assembly includes an end reversing pulley 50 and an intermediate reversing pulley 60. The end reversing pulley 50 is set at a preset position, and the intermediate reversing pulley 60 is set between the end reversing pulley 50 and the protective cover 10. The rotation axis of the end reversing pulley 50 is perpendicular to the insertion direction of the coil 70, and the rotation axis of the intermediate reversing pulley 60 is parallel to the insertion direction of the coil 70. In other words, the rotation axis of the end reversing pulley 50 is a horizontal rotation axis, that is, the end reversing pulley 50 rotates in a vertical plane; the rotation axis of the intermediate reversing pulley 60 is a vertical rotation axis, that is, the intermediate reversing pulley 60 rotates in a horizontal plane.

[0048] In this embodiment, there are two end diverting pulleys 50, which are spaced apart. There are two transmission wires 20, which are slidably wound around the two end diverting pulleys 50, and the second ends of the two transmission wires 20 are respectively connected to the two ends of the mating member 30. In other words, the two end diverting pulleys 50 position the mating member 30 at a predetermined position.

[0049] In this embodiment, there is at least one intermediate reversing pulley 60. When there are multiple intermediate reversing pulleys 60, the multiple intermediate reversing pulleys 60 are spaced apart. By providing multiple intermediate reversing pulleys 60, the tension of the transmission wire 20 is ensured, and the transmission effect of the transmission wire 20 is ensured.

[0050] Furthermore, in order to support the switching components, e.g. Figures 3 to 5 As shown, the protective device also includes a pulley support 90. The pulley support 90 includes a base plate, a first support column, and a second support column. The first support column and the second support column are respectively disposed on the base plate. The end diverting pulley 50 is movably connected to the top of the first support column, and the middle diverting pulley 60 is rotatably connected to the top of the second support column. Specifically, the top of the first support column has a central recess. The end diverting pulley 50 is vertically accommodated in the central recess and connected to the inner walls of the central recess on both sides via a horizontal rotation axis, thereby enabling vertical rotation.

[0051] In this embodiment, the height of the first support column is greater than the width of the electrical connection hole 83. It is understood that the height of the first support column is positively correlated with the movable distance of the protective cover 10. Before the coil 70 compresses the mating component 30 to its lowest point, the mating component 30 has already driven the protective cover 10 completely out of the way of the electrical connection hole 83.

[0052] In this embodiment, there are two intermediate reversing pulleys 60, the bottom plate is a Z-shaped plate, and the two end reversing pulleys 50 and the two intermediate reversing pulleys 60 are respectively located at the two ends of the bottom plate. Among them, along the length direction of the socket 80, the end reversing pulley 50 is located on the side close to the electrical connection hole 83, and the intermediate reversing pulley 60 is located on the side away from the electrical connection hole 83, so as to facilitate the connection between the transmission wire 20 and the protective cover 10. The two end reversing pulleys 50 and the two intermediate reversing pulleys 60 are all arranged at intervals along the width direction of the socket 80. Along the width direction of the socket 80, the intermediate reversing pulley 60 is closer to the fixed seat 82 relative to the end reversing pulley 50. In other words, the arrangement of the transmission wire 20 is roughly U-shaped, and reversing is achieved through the intermediate reversing pulley 60 and the matching piece 30 is arranged on the left and right sides of the fixed seat 82.

[0053] Specifically, such as Figure 4 As shown, the fitting 30 includes a first connecting section 31, an extruded section 32 and a second connecting section 33 connected in sequence. The first connecting section 31 and the second connecting section 33 are respectively connected to the second ends of the two transmission wires 20, and the extruded section 32 is used to be extruded and matched with the coil 70. Furthermore, the width of the extruded section 32 is greater than the width of the first connecting section 31 and the second connecting section 33 so as to have a larger extruded area. In the present embodiment, the extruded section 32 is circular. Of course, the extruded section 32 can also be other shapes such as square. The fitting 30 is located as a whole on one side of the two end reversing pulleys 50, and a portion of the extruded section 32 can extend between the two end reversing pulleys 50. It can be understood that the fitting 30 is arranged horizontally, and the second ends of the two transmission wires 20 are respectively connected and fixed to the top surfaces of the first connecting section 31 and the second connecting section 33.

[0054] In this embodiment, the fitting member 30 is a spring structure, which has a certain elasticity and better contacts the coil 70 .

[0055] like Figures 3 to 5 As shown, a limiting sleeve 11 is provided at the end of the protective cover 10 , and the limiting sleeve 11 extends along the moving direction of the protective cover 10 . The first end of the elastic reset member 40 is passed through the limiting sleeve 11 , thereby stopping and limiting the elastic reset member 40 .

[0056] In this embodiment, there are two fitting members 30 and two elastic return members 40, each symmetrically arranged on either side of the protective cover 10. Furthermore, there are two reversing assemblies, also symmetrically arranged on either side of the protective cover 10. Similarly, there are two pulley supports 90, also symmetrically arranged on either side of the protective cover 10; and there are two limit sleeves 11, also located on the left and right ends of the protective cover 10. In other words, the protective device as a whole is symmetrically arranged, and the arrangement of the transmission structures on the left and right sides makes the movement of the protective cover 10 more stable, preventing deviations that could affect the connection between the coil 70 and the socket 80.

[0057] like Figures 1 to 2 、 Figures 6 to 11 As shown, the present application also provides a nuclear magnetic resonance apparatus, comprising a coil 70, a socket 80, and the aforementioned protective device 100 for the nuclear magnetic resonance apparatus, wherein the coil 70 is electrically connected to the socket 80. Furthermore, the nuclear magnetic resonance apparatus further comprises a main body 200 for a patient to lie flat, and the socket 80 is disposed on the main body 200.

[0058] In this embodiment, coil 70 is a head coil, main body 200 is a strip-shaped bed board, and socket 80 is located at the upper end of main body 200 for performing an MRI scan of the patient's head. Of course, coil 70 can also be other types of coils, which can be selected according to actual needs.

[0059] It should be noted that the length direction and width direction of the socket 80 are respectively the same as the length direction and width direction of the main body 200 .

[0060] In this embodiment, the socket 80 has a housing space, within which the protective device 100 is housed. Specifically, the socket 80 includes a housing, which defines the aforementioned housing space and includes a recessed portion for plugging and mating with the coil 70. Furthermore, the protective device 100 and the fixing seat 82 are both located within the housing space, ensuring the overall aesthetics of the socket 80.

[0061] like Figures 3 to 5As shown, the socket 80 is provided with a positioning post 81, which extends along the moving direction of the protective cover 10. The second end of the elastic return member 40 is sleeved on the positioning post 81. The positioning post 81 is spaced apart from the limiting sleeve 11 of the protective cover 10, or the positioning post 81 is inserted into the limiting sleeve 11. Specifically, the positioning post 81 is provided on a fixing seat 82, and the positioning post 81 and the limiting sleeve 11 are coaxially arranged. The inner diameter of the limiting sleeve 11 is larger than the inner diameter of the positioning post 81, so that both the elastic return member 40 and the limiting sleeve 11 can be sleeved on the positioning post 81, and the elastic return member 40 is sandwiched between the limiting sleeve 11 and the positioning post 81. In this way, under the action of friction, the elastic return member 40 is compressed during the movement of the protective cover 10 to the first position, so that the elastic return member 40 drives the protective cover 10 to return to the second position when the coil 70 is pulled out of the socket 80.

[0062] In an optional embodiment, the first end of the elastic return member 40 abuts the limiting sleeve 11. Specifically, the limiting sleeve 11 is mounted on the positioning post 81, and the inner diameter of the limiting sleeve 11 matches the inner diameter of the positioning post 81. This prevents the elastic return member 40 from entering the limiting sleeve 11 and abuts against the end surface of the limiting sleeve 11. The cooperation between the positioning post 81 and the limiting sleeve 11 provides guidance for the movement of the protective cover 10, ensuring smooth and stable movement of the protective cover 10.

[0063] like Figures 6 and 7 、 Figure 9 As shown, the coil 70 includes a guide post 71. In response to the coil 70 being inserted into the electrical connection hole 83 of the socket 80, the guide post 71 presses the fitting 30 to move along the insertion direction of the coil 70, so that the transmission wire 20 drives the protective cover 10 to move from the second position to the first position. Figure 7 and Figure 9 As shown, a guide hole 84 is correspondingly opened in the housing of the socket 80 , and the guide post 71 extends into the socket 80 through the guide hole 84 and presses the fitting 30 .

[0064] In this embodiment, corresponding to the two fitting pieces 30 on the left and right sides, there are also two guide posts 71 and two guide holes 84 , so that the coil 70 can be stably inserted into the socket 80 .

[0065] Further, such as Figure 10 As shown, the housing of the socket 80 also defines a relief hole 85, which is positioned vertically corresponding to the electrical connection hole 83 of the fixing base 82. The protective cover 10 is positioned between the relief hole 85 and the electrical connection hole 83, and opens and closes the hole by horizontal movement. It is understood that the two guide holes 84 are located on the left and right sides of the relief hole 85.

[0066] The plugging process of the coil 70 and the socket 80 in this embodiment is as follows:

[0067] like Figure 7 As shown, when the user inserts the guide post 71 of the coil 70 downward along the guide hole 84 into the socket 80, as the coil 70 is pressed downward, the guide post 71 will touch the mating piece 30 and squeeze the mating piece 30 downward. The mating piece 30 will pull the protective cover 10 to the rear side through the transmission wire 20 to open. At this time, the elastic return member 40 is gradually compressed, and the electrical connection hole 83 in the socket 80 is also exposed, so that it can be plugged with the coil 70. When the user pulls the coil 70 out of the socket 80, the guide post 71 releases the pressure on the mating piece 30. At this time, the protective cover 10 will automatically return to its original position to block the electrical connection hole 83 under the reset force of the elastic return member 40, and the mating piece 30 will also rise to its highest point, thereby realizing the automatic opening and closing of the protective cover 10.

[0068] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: the protective device for nuclear magnetic resonance equipment includes a protective cover 10, a transmission wire 20, a matching piece 30 and an elastic reset piece 40, the protective cover 10 is adjustably arranged on the socket 80 of the nuclear magnetic resonance equipment, the protective cover 10 has a first position to avoid the electrical connection hole 83 of the socket 80 and a second position to block the electrical connection hole 83 of the socket 80, the first end of the transmission wire 20 is connected to the protective cover 10, and the second end of the transmission wire 20 is connected to the matching piece 30, in response to the coil 70 of the nuclear magnetic resonance equipment being inserted into the electrical connection hole 83, the matching piece 30 is squeezed by the coil 70 and moves along the insertion direction of the coil 70, so as to drive the protective cover 10 to move from the second position to the first position through the transmission wire 20, and the elastic reset piece 40 The protective cover 10 is used to provide a reset force for returning the protective cover 10 from the first position to the second position. The mating member 30 is connected to the protective cover 10 via the transmission wire 20, so that when the coil 70 of the nuclear magnetic resonance device is inserted into the electrical connection hole 83 of the socket 80, the mating member 30 can be pressed to move along the insertion direction of the coil 70, thereby driving the protective cover 10 to open via the transmission wire 20, so that the coil 70 and the socket 80 can be plugged together. When the coil 70 is withdrawn from the socket 80, the reset force of the elastic reset member 40 can automatically restore the protective cover 10 to a state that covers the electrical connection hole 83 of the socket 80. This allows the electrical connection hole 83 to be automatically opened and closed without manual operation, saving operation steps and time, while preventing the user from forgetting to close the protective cover 10, and greatly improving the dustproof effect of the nuclear magnetic resonance device. In addition, the use of the transmission wire 20 can also prevent the protective device from introducing magnetic components, thereby avoiding any impact on the nuclear magnetic resonance device.
