Description
Technical Field
[0001] This utility model relates to the field of nuclear magnetic resonance technology, and more specifically, to a nuclear magnetic resonance chest and abdominal coil protection device. Background Technology
[0002] The MRI chest and abdomen coil protection device is a device used to protect the chest and abdomen coils in an MRI scanner.
[0003] Currently, the typical protective device for the MRI chest and abdominal coils involves the operator directly inserting the coil into a clip for fixation. However, in use, if a collision occurs, the MRI chest and abdominal coil may loosen and detach from the clip, reducing the stability of the coil installation. Furthermore, the coil may wobble due to the impact, causing wear and tear, which can damage the MRI chest and abdominal coil and affect the normal operation of the MRI scanner. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a protective device for the MRI chest and abdominal coil, which has the advantages of fixing the position of the MRI chest and abdominal coil and reducing the wear of the MRI chest and abdominal coil, which may lead to the inability to use it.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a nuclear magnetic resonance chest and abdominal coil protection device, comprising a base, a first mounting seat fixedly connected to the top of the base, a second mounting seat fixedly connected to the top of the base, two support columns fixedly connected to the top of each of the first and second mounting seats, abutting the top of the first and second mounting seats against a nuclear magnetic resonance chest and abdominal coil, a clamping assembly provided on the outside of the support columns, the clamping assembly comprising two liquid storage cylinders fixedly connected to the inside of the support columns, a first diverter pipe fixedly connected to the end of each liquid storage cylinder, the first diverter pipe communicating with the inside of the liquid storage cylinder, an inlet pipe fixedly connected to the outside of the first diverter pipe, the inlet pipe communicating with the inside of the first diverter pipe, a solenoid valve fixedly connected inside the inlet pipe, a slide rod slidably connected inside the liquid storage cylinder, a connecting block fixedly connected to the end of the slide rod, and a soft clamping block fixedly connected to the outside of the connecting block.
[0006] As a preferred technical solution of this utility model, an adsorption component is provided on the outside of the soft clamping block. The adsorption component includes a second diversion pipe fixedly connected to the top of the soft clamping block. The second diversion pipe communicates with the inside of the soft clamping block. An air extraction pipe is fixedly connected to the outside of the second diversion pipe. A solenoid valve is fixedly connected inside the air extraction pipe. The air extraction pipe communicates with the inside of the second diversion pipe.
[0007] As a preferred technical solution of this utility model, a pressing component is provided on the outside of the support column. The pressing component includes a slider that is slidably connected to the inside of the support column. A top pressing block is fixedly connected to the top of the slider. The bottom of the top pressing block abuts against the top of the MRI chest and abdomen coil.
[0008] As a preferred technical solution of this utility model, a limiting component is provided on the outside of the support column. The limiting component includes a locking block that is slidably connected inside the slider. The locking block passes through the support column and is slidably connected. A U-shaped rod is fixedly connected to the outside of the locking block.
[0009] As a preferred embodiment of the present invention, the limiting component further includes a limiting block slidably connected to the outside of the U-shaped rod, the limiting block being fixedly connected to the outside of the support column, and a spring being fixedly connected between the locking block and the limiting block.
[0010] As a preferred technical solution of this utility model, a stabilizing component is provided on the outer side of the base. The stabilizing component includes six support rods that are fixedly connected to both ends of the outer side of the base, and a stabilizing seat is fixedly connected to the end of each support rod.
[0011] As a preferred embodiment of this utility model, the outer side of the soft clamping block abuts against the outer side of the MRI chest and abdominal coil, and high-pressure gas sealant is applied to the connection between the soft clamping block and the MRI chest and abdominal coil.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model injects damping oil into the reservoir to push the slide rod, which in turn moves the connecting block, causing the soft clamping block to clamp the outer shell of the MRI chest and abdomen coil. At the same time, the air inside the soft clamping block is expelled, allowing the soft clamping block to adhere to the outer shell of the MRI chest and abdomen coil, thus restricting the position of the outer shell of the MRI chest and abdomen coil. The damping oil inside the reservoir can absorb the impact force transmitted from the outside, thus ensuring the stability of the device. This prevents the coil from being worn due to collisions with the outer shell of the MRI chest and abdomen coil, thus ensuring the normal use of the MRI imager.
[0014] 2. This utility model uses the movement of a slider to push the locking block, thereby moving the U-shaped rod and compressing the spring. When the slider moves to the designated position, the spring will drive the locking block to move, so that the locking block enters the slider and fixes the position of the slider. This ensures that the top pressing block can always be at the top of the MRI thoracic and abdominal coil shell, thus fixing the position of the MRI thoracic and abdominal coil shell.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 6As shown, this utility model provides a protective device for a MRI chest and abdominal coil, including a base 1, a first mounting seat 2 fixedly connected to the top of the base 1, a second mounting seat 3 fixedly connected to the top of the base 1, two support columns 4 fixedly connected to the top of both the first mounting seat 2 and the second mounting seat 3, and an MRI chest and abdominal coil 5 abutting against the top of the first mounting seat 2 and the second mounting seat 3. A clamping assembly is provided on the outside of the support columns 4, the clamping assembly including two liquid storage cylinders 6 fixedly connected to the inside of the support columns 4, a first diversion pipe 8 fixedly connected to the end of the liquid storage cylinder 6, the first diversion pipe 8 communicating with the inside of the liquid storage cylinder 6, an inlet pipe 9 fixedly connected to the outside of the first diversion pipe 8, the inlet pipe 9 communicating with the inside of the first diversion pipe 8, a solenoid valve fixedly connected inside the inlet pipe 9, a slide rod 7 slidably connected inside the liquid storage cylinder 6, a connecting block 10 fixedly connected to the end of the slide rod 7, and a soft clamping block 11 fixedly connected to the outside of the connecting block 10.
[0024] By injecting damping oil into the first shunt pipe 8, the damping oil is injected into the reservoir 6, which pushes the slide rod 7, thereby moving the connecting block 10. This causes the soft clamping block 11 to clamp the outer shell of the MRI chest and abdomen coil. Continuing to inject oil removes air from the soft clamping block 11, allowing it to adhere to the outer shell of the MRI chest and abdomen coil, thus restricting its position. The damping oil inside the reservoir 6 absorbs the impact force transmitted from the outside, ensuring the stability of the device and preventing wear of the coil due to impacts to the outer shell. This ensures the normal operation of the MRI imager.
[0025] The soft clamping block 11 is provided with an adsorption component on its outer side. The adsorption component includes a second diversion pipe 12 fixedly connected to the top of the soft clamping block 11. The second diversion pipe 12 is connected to the interior of the soft clamping block 11. An air extraction pipe 13 is fixedly connected to the outer side of the second diversion pipe 12. A solenoid valve is fixedly connected inside the air extraction pipe 13. The air extraction pipe 13 is connected to the interior of the second diversion pipe 12.
[0026] The air inside the soft clamping block 11 can be collected through the second diversion pipe 12, and then the air can be transferred to the air extraction pipe 13 to discharge the air.
[0027] The support column 4 is provided with a pressing component on its outer side. The pressing component includes a slider 15 that is slidably connected to the inside of the support column 4. A top pressing block 14 is fixedly connected to the top of the slider 15. The bottom of the top pressing block 14 abuts against the top of the MRI chest and abdomen coil 5.
[0028] By moving the slider 15, the top pressing block 14 is moved to the top of the MRI thoracic and abdominal coil housing, thereby pressing the top of the MRI thoracic and abdominal coil housing.
[0029] The support column 4 is provided with a limiting component on its outer side. The limiting component includes a locking block 16 that is slidably connected to the inside of the slider 15. The locking block 16 passes through the support column 4 and is slidably connected. A U-shaped rod 17 is fixedly connected to the outer side of the locking block 16.
[0030] The limiting assembly also includes a limiting block 18 that is slidably connected to the outside of the U-shaped rod 17. The limiting block 18 is fixedly connected to the outside of the support column 4. A spring 19 is fixedly connected between the locking block 16 and the limiting block 18.
[0031] By moving the slider 15, the locking block 16 is pushed, which in turn moves the U-shaped rod 17, thereby compressing the spring 19. When the slider 15 moves to the designated position, the spring 19 will drive the locking block 16 to move, so that the locking block 16 enters the slider 15, thereby fixing the position of the slider 15. This ensures that the top pressing block 14 can always be at the top of the MRI thoracic and abdominal coil shell, thus fixing the position of the MRI thoracic and abdominal coil shell.
[0032] The base 1 has a stabilizing component on its outer side, which includes six support rods 20 that are fixedly connected to both ends of the outer side of the base 1, and a stabilizing seat 21 is fixedly connected to the end of each support rod 20.
[0033] The base 1 can be supported by the cooperation of the stabilizing seat 21 and the support rod 20, thereby increasing the contact area with the ground and thus increasing the stability of the device.
[0034] The soft clamping block 11 abuts against the outer side of the MRI chest and abdomen coil 5, and high-pressure gas sealant is applied to the connection between the soft clamping block 11 and the MRI chest and abdomen coil 5.
[0035] By applying high-pressure gas sealant between the soft clamping block 11 and the MRI chest and abdominal coil 5, the two are bonded more tightly and gas is prevented from entering between them, thus making the adsorption tighter.
[0036] The working principle and usage process of this utility model are as follows: Damping oil is injected into the first diversion pipe 8, thereby injecting it into the reservoir 6. This pushes the slide rod 7, causing the connecting block 10 to move, which in turn causes the soft clamping block 11 to clamp the outer shell of the MRI chest and abdomen coil. Continued injection removes air from the soft clamping block 11, allowing it to adhere to the outer shell of the MRI chest and abdomen coil, thus restricting its position. The damping oil inside the reservoir 6 absorbs the impact force transmitted from the outside, ensuring the stability of the device and preventing coil wear due to impacts to the outer shell of the MRI chest and abdomen coil. This ensures the normal operation of the MRI imaging device.
