The nuclear magnetic resonance radio frequency coil is a key component for exciting and collecting nuclear magnetic resonance signals. By adjusting the capacitance value of the adjustable capacitor connected to the coil, the resonance point of the radio frequency coil can be tuned to the resonance frequencies of different nuclides, thereby achieving the purpose of observing nuclear magnetic resonance signals of different nuclides.

[0003] The current mainstream in the nuclear magnetic resonance system market is provided by three major foreign brands, namely GE / SIEMENS / PHILIPS suppliers, resulting in the emergence of special maintenance detection instruments for nuclear magnetic resonance coils on the market.

[0009] Preferably, the pneumatic telescopic rod is fixedly inserted on one side of a combination panel away from an operating channel.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In this application, the operation channel provides a channel for matching connection with the plug of the nuclear magnetic resonance coil. The second combined plate provides a support platform during the detection of the nuclear magnetic resonance coil by the nuclear magnetic resonance coil repair detection device, facilitating the placement of the nuclear magnetic resonance coil and keeping the nuclear magnetic resonance coil away from the top of the installation box, without affecting the operation and viewing of the vector network analysis module, multi-channel radio frequency signal multiplexer, low-noise preamplifier detection module, and multi-channel signal acquisition and recording module by the nuclear magnetic resonance coil.

[0018] 2. When the nuclear magnetic resonance coil repair detection equipment in this application is not working, the sealing frame and the installation box cooperate to seal and store the port of the nuclear magnetic resonance coil. At this time, the two combined plate parts I fixedly installed on both sides inside the installation box, the combined plate part II arranged between the two combined plate parts I, and the combined plate part III arranged inside the operation channel opened on the combined plate part II form a sealing cover to seal the top of the installation box, so that the vector network analysis module, the multi-channel radio frequency signal multiplexer, the low-noise preamplifier detection module, the multi-channel signal acquisition and recording module, and the port of the nuclear magnetic resonance coil are sealed and protected by the sealing cover, which is convenient for moving the nuclear magnetic resonance coil repair detection equipment and ensures the convenience of using the nuclear magnetic resonance coil repair detection equipment.

[0019] 3.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment: As Figures 1 - 13As shown, the present invention provides a technical solution of a maintenance and detection instrument for a nuclear magnetic resonance coil, comprising a nuclear magnetic resonance coil maintenance and detection device 1 and a power socket 4 installed on one side of the nuclear magnetic resonance coil maintenance and detection device 1, the nuclear magnetic resonance coil maintenance and detection device 1 comprises an installation box 11, a vector network analysis module 12, a multi-channel radio frequency signal multiplexer 13, a low-noise preamplifier detection module 14, a multi-channel signal acquisition and recording module 15 and a nuclear magnetic resonance coil port 16, an outward movement channel 18 is opened on one side of the installation box 11, a sealing frame 17 is arranged inside the outward movement channel 18, the sealing frame 17 is fixedly connected to the nuclear magnetic resonance coil port 16, and the sealing A nuclear magnetic resonance line support structure 2 is installed between the frame 17 and the installation box 11, and the nuclear magnetic resonance line support structure 2 includes a transmission frame 21 and a pneumatic telescopic rod 24. A combination panel 2 110 is fixedly installed on one side of the transmission frame 21, and an operation channel 111 is opened on one side of the combination panel 2 110. The transmission frame 1 21 is fixedly connected to two transmission frames 3 23, and the tops of the two transmission frames 3 23 are both provided with limiting components. An external structure 3 is arranged between the two transmission frames 3 23 and the installation box 11, and the external structure 3 includes a handle 1 32, two wire tubes 33 fixedly connected on both sides of the handle 1 32, and a pull wire 34 passing through the wire tube 33.

[0036] Specifically, the vector network analysis module 12, the multi-channel RF signal multiplexer 13, the low-noise preamplifier detection module 14, and the multi-channel signal acquisition and recording module 15 are all fixedly installed inside the installation box 11, and the nuclear magnetic resonance coil port 16 can slide inside the installation box 11. An outward movement channel 18 is opened on one side of the installation box 11. The sealing frame 17 arranged inside the outward movement channel 18 is fixedly connected to the nuclear magnetic resonance coil port 16. When the nuclear magnetic resonance coil repair detection device 1 is not working, the sealing frame 17 cooperates with the installation box 11 to seal and store the nuclear magnetic resonance coil port 16. At this time, the two sides of the installation box 11 are fixed. The sealing cover composed of two fixedly installed combination panels 19, a combination panel 2 110 arranged between the two combination panels 19, and a combination panel 3 112 arranged inside the operation channel 111 opened on the combination panel 2 110 seals the top of the installation box 11, so that the vector network analysis module 12, the multi-channel RF signal multiplexer 13, the low-noise preamplifier detection module 14, the multi-channel signal acquisition and recording module 15, and the nuclear magnetic resonance coil port 16 are sealed and protected by the sealing cover, which facilitates the movement of the nuclear magnetic resonance coil repair detection equipment 1 and ensures the convenience of using the nuclear magnetic resonance coil repair detection equipment 1.

[0037] Moreover, the composite plate member three 112 is fixedly connected to the adjacent composite plate member one 19, and the composite plate member three 112 cannot move inside the installation box 11. A first reserved channel 113 is provided on one side of the composite plate member two 110, and the first reserved channel 113 communicates with the operation channel 111. The arrangement of the composite plate member three 112 does not affect the movement of the composite plate member two 110. One end of the composite plate member two 110 penetrates through the installation box 11 and extends to the outside of the installation box 11, enabling the composite plate member two 110 to slide on the installation box 11.

[0038] When the power socket 4 installed on one side of the nuclear magnetic resonance coil repair detection device 1 is connected to the power supply, the nuclear magnetic resonance coil repair detection device 1 enters the working state. The pneumatic telescopic rod 24 fixedly inserted on one side of the composite plate member one 19 away from the operation channel 111 extends. Since a second reserved channel 25 is provided on the outside of the installation box 11, the extending end of the pneumatic telescopic rod 24 penetrates through the second reserved channel 25 and is fixedly connected to the first transmission frame 21. Therefore, the working pneumatic telescopic rod 24 pushes the first transmission frame 21 to move, causing the first transmission frame 21 to drive the fixedly connected composite plate member two 110 to move towards the outside of the installation box 11.

[0039] Two second transmission frames 22 are fixedly connected between the first transmission frame 21 arranged outside the installation box 11 and the sealing frame 17, and the sealing frame 17 is fixedly connected to the nuclear magnetic resonance coil port 16. Therefore, the first transmission frame 21 drives the nuclear magnetic resonance coil port 16 to move through the second transmission frames 22 and the sealing frame 17, causing the nuclear magnetic resonance coil port 16 to leave the inside of the installation box 11 after passing through the outward movement channel 18. The nuclear magnetic resonance coil port 16 moves synchronously with the composite plate member two 110, and the relative position between the operation channel 111 arranged on the top of the nuclear magnetic resonance coil port 16 and the nuclear magnetic resonance coil port 16 remains unchanged. When the nuclear magnetic resonance coil port 16 leaves the inside of the installation box 11, the composite plate member three 112 leaves from the inside of the operation channel 111.

[0040] After the pneumatic telescopic rod 24 finishes working, after the staff places the nuclear magnetic resonance coil on the top of the composite plate member two 110, the operation channel 111 provides a channel for the 7 to be matched and connected with the nuclear magnetic resonance coil plug. The composite plate member two 110 provides a support platform during the detection of the nuclear magnetic resonance coil by the nuclear magnetic resonance coil repair detection device 1, facilitating the placement of the nuclear magnetic resonance coil and enabling the nuclear magnetic resonance coil to leave the top of the installation box 11, without affecting the operation and viewing of the vector network analysis module 12, multi-channel radio frequency signal multiplexer 13, low-noise preamplifier detection module 14, and multi-channel signal acquisition and recording module 15 by the nuclear magnetic resonance coil.

[0041] Subsequently, through the detection circuit and the corresponding RF cables, the vector network analysis module 12, the multi-channel RF signal multiplexer 13, and the multi-channel signal acquisition and recording module 15 are connected to the target nuclear magnetic resonance (NMR) coil. Then, the power switches of the vector network analysis module 12, the multi-channel RF signal multiplexer 13, the low-noise preamplifier detection module 14, and the multi-channel signal acquisition and recording module 15 are turned on to start these modules. According to the model of the target NMR coil, the multi-channel RF signal multiplexer 13 selects single / multi channels and controls the working state of the tuning / desynchronizing circuit of the selected channels by loading / unloading DC bias voltages. At the same time, the receiving / transmitting circuit of the selected channels of the NMR coil operates in a certain output mode, realizing the test of different functional parts of the NMR coil. According to the model of the target NMR coil, the multi-channel signal acquisition and recording module 15 collects and records the working current signals of the selected single / multi channels, and sets the normal working range of the current signals. An alarm function is available when the range is exceeded.

[0042] Subsequently, the resonant frequency of the corresponding NMR system is confirmed. The vector network analysis module 12, together with a supporting special detection probe, is used to measure parameters such as the voltage standing wave ratio (VSWR) and return loss of the receiving / transmitting circuit of the selected channels. In the RF multiplexing working state, the vector network analysis module 12 measures the insertion loss parameters of each selected RF channel. If the measured insertion loss is out of tolerance, the vector network analysis module 12 can check the cable fault points of each RF channel for analysis and judgment. In addition, the vector network analysis module 12, in cooperation with the low-noise preamplifier detection module 14, can measure the amplification factor of the low-noise preamplifier of NMR coils of different brands and compare it with the test results of the NMR coil in the normal state to confirm the working state of the target NMR coil. If it is unqualified, targeted maintenance can be carried out in a timely manner.

[0043] In addition, such as Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown in the figure, drive frames three 23 are fixedly connected to both ends of drive frame one 21. Two reserved channels three 26 are provided on the outer side of installation box 11. The two drive frames three 23 are respectively inserted into the two reserved channels two 25. A curved surface clamping block 214 is fixedly connected to the end of drive frame three 23 far from drive frame one 21. The curved surface clamping block 214 abuts against installation box 11. Drive frame three 23 and pneumatic telescopic rod 24 cooperate to limit and guide the movement of drive frame one 21, ensuring that drive frame one 21 can drive combined plate member two 110 to smoothly return to the interior of installation box 11. Drive frame three 23 shares the acting force received by pneumatic telescopic rod 24 to protect pneumatic telescopic rod 24. A blocking block 215 is arranged on one side of curved surface clamping block 214. The blocking block 215 is fixedly connected to installation box 11 to seal reserved channel three 26, preventing external impurities from entering reserved channel three 26 and affecting the movement of drive frame three 23 and curved surface clamping block 214;

[0044] In the limiting component, storage box 27 is arranged inside reserved channel three 26 and fixedly connected to drive frame one 21. Storage box 27 and blocking block 215 are arranged at both ends of reserved channel three 26. Storage box 27 limits the movement of curved surface clamping block 214 to prevent drive frame three 23 from completely separating from installation box 11. Drive frame three 23 supports drive frame one 21 to ensure the stability of the support of drive frame one 21 and combined plate member two 110 for the nuclear magnetic resonance coil.

[0045] In addition, as Figure 7 and Figure 8 shown in the figure, a clamping groove 212 is provided at the bottom of storage box 27. The clamping groove 212 is opened at the top of drive frame three 23. And a metal block 28 is provided at the bottom of the electromagnet 29 fixedly connected to the top of the inner cavity of storage box 27. The metal block 28 is made of iron. Spring type telescopic rods 210 and two telescopic rods one 211 are fixedly connected to both sides of the top of metal block 28. The tops of the retractable spring type telescopic rods 210 and telescopic rods one 211 are fixedly connected to storage box 27. When electromagnet 29 is not working, the spring type telescopic rod 210 expands and contracts to push the metal block 28 downward, and part of the metal block 28 enters the clamping groove 212, making the metal block 28 in a state of being partially inside the clamping groove 212 and partially inside the storage box 27. The metal block 28 plays a role in limiting drive frame three 23 to ensure the stability of drive frame three 23 staying inside reserved channel three 26;

[0046] When pneumatic telescopic rod 24 works, electromagnet 29 works synchronously. The working electromagnet 29 pulls the metal block 28 upward by magnetic force, making the metal block 28 leave the inside of the clamping groove 212, so that drive frame three 23 loses its fixation, and drive frame one 21 and drive frame three 23 can move.

[0047] In addition, as Figure 7 、 Figure 9 、Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown in Figure 13 , two connecting rods 31 are fixedly connected between the first handle 32 and the mounting box 11. The first handle 32 and the two connecting rods 31 form a U-shaped handle on one side of the mounting box 11, which facilitates the handling of the nuclear magnetic resonance coil repair and detection device 1.

[0048] Two pull wires 34 inserted inside two wire conduits 33 fixedly connected to both sides of the first handle 32 are respectively fixedly connected to two third driving frames 23. When the first driving frame 21 moves away from the mounting box 11, the third driving frame 23 moves to apply a pulling force to the pull wire 34. A wire reel 36 is fixedly connected to the other end of the pull wire 34. Part of the pull wire 34 is wound around the wire reel 36. The mounting cross bar 310 fixedly connected inside the wire reel 36 is rotatably connected to the first handle 32. When the third driving frame 23 pulls the pull wire 34, the mounting cross bar 310 and the wire reel 36 rotate to unwind the pull wire 34. A circular groove 216 is formed in the third driving frame 23. One end of the wire conduit 33 extends into the circular groove 216 after passing through the sealing block 215. One end of the pull wire 34 deflected by the wire conduit 33 is pulled by the third driving frame 23; A torsion spring box 38 is arranged on one side of the mounting cross bar 310, and a torsion spring 39 is installed inside the torsion spring box 38. One end of the torsion spring 39 extends outside the torsion spring box 38 and is fixedly connected to the mounting cross bar 310. When the mounting cross bar 310 rotates, the torsion spring 39 installed inside the torsion spring box 38 fixedly installed on the first handle 32 at this time is wound outside the mounting cross bar 310;

[0049] After the third driving frame 23 is reset, the torsion spring 39 rebounds to drive the mounting cross bar 310 to rotate, so that the mounting cross bar 310 drives the wire reel 36 to rotate and wind up the redundant pull wire 34, so that the pull wire 34 is always in a taut state, avoiding the influence of the pull wire 34 on the handling of the nuclear magnetic resonance coil repair and detection device 1, and ensuring the service life of the peripheral structure 3.

[0050] A storage groove 35 is formed on one side of the grip 32. Two telescopic rods II 311 are arranged inside the storage groove 35. A grip II 315 is fixedly connected between the two telescopic rods II 311 that can be telescoped. The grip II 315 can move on one side of the grip 32. When the user advances the nuclear magnetic resonance coil repair and detection device 1 through the handle, under the action of the weight of the nuclear magnetic resonance coil repair and detection device 1, the grip II 315 moves and presses against the grip 32. A clamping rod 313 inserted inside the clamping box 312 is fixedly connected to the grip II 315. Therefore, when the grip II 315 moves towards the grip 32 and the two are pressed against each other, the clamping rod 313 moves towards the inside of the clamping box 312, and the pull wire 34 passes through a wire groove 314 formed on the clamping box 312. Therefore, the part of the wire groove 314 located inside the clamping box 312 is pressed by the clamping rod 313. The clamping box 312 is fixedly connected to the grip 32 and cannot move, so that the pull wire 34 is clamped and limited by the cooperation of the clamping box 312 and the clamping rod 313. The transmission frame III 23 fixedly connected to the pull wire 34 is limited and cannot move. When the nuclear magnetic resonance coil repair and detection device 1 is lifted and moved, the weight of the nuclear magnetic resonance coil repair and detection device 1 acts on the pull wire 34 and is converted into a force that restricts the transmission frame III 23 and the transmission frame I 21. To avoid the situation where the pneumatic telescopic rod 24 and the spring telescopic rod 210 get out of control due to the shaking and vibration of the nuclear magnetic resonance coil repair and detection device 1, the transmission frame I 21 can move to drive the nuclear magnetic resonance coil port 16 to leave the inside of the installation box 11, ensuring the safety of the nuclear magnetic resonance coil port 16 and reducing the damage to the internal equipment of the nuclear magnetic resonance coil repair and detection device 1 caused by the movement of the nuclear magnetic resonance coil repair and detection device 1.

[0051] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description.
