Description

Technical Field

[0001] The invention relates to the technical field of assembled hospitals, and in particular to a medical magnetic shielding cabin. Background Art

[0002] The magnetic shielding of the MRI room is one of the key factors to ensure the normal operation of the MRI instrument. MRI examination is of great significance in clinical applications, especially in the field of neurology. However, strong magnetic fields will have an impact on the surrounding environment and the human body, so effective magnetic shielding measures need to be taken. In addition to selecting appropriate magnetic shielding materials, the magnetic shielding design of the MRI room also needs to consider many factors, such as the uniformity of the magnetic field, the thickness and structure of the shielding layer, etc.

[0003] In order to ensure the shielding effect, it is usually necessary to adopt a multi-layer magnetic shielding structure and take good grounding measures to reduce the impact of external magnetic fields on the nuclear magnetic resonance instrument.

[0004] MRI receives electromagnetic signals. If the shielding is not done well, the external magnetic field and electromagnetic will interfere with the MRI image. The lamps and other electronic equipment in the MRI room are dedicated to MRI. Any electrical appliance may affect the MRI image. The higher the field strength, the greater the impact.

[0005] Electromagnetic shielding projects mainly shield and isolate magnetic and radio frequency in hospitals to reduce the impact of radiation factors on hospital work. The quality control points of electromagnetic shielding include the welding connection between copper mesh or copper plate, the welding connection between shielding window and shielding wall, and the installation of spring sheet in the gap of shielding door.

[0006] In primary medical institutions, there is a serious shortage of equipment such as nuclear magnetic resonance imaging, which has resulted in primary medical care failing to meet the needs of high-quality development. At present, the construction of nuclear magnetic resonance testing rooms at the grassroots level requires that the transportation of nuclear magnetic resonance instruments not only ensure magnetic shielding and be unaffected by the external environment, so that nuclear magnetic resonance will not radiate and affect the outside world, but also need to cope with different road environments to ensure that the transportation process will not cause damage to the instrument and meet earthquake resistance requirements.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are only for the purpose of enabling the reader to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0039] like Figure 1-Figure 5 As shown, a medical magnetic shielding cabin is used to place a nuclear magnetic resonance apparatus 100. The cabin includes an outer shell 200 and an inner shell 300. The outer shell 200 is sleeved on the inner shell 300. The inner wall of the outer shell 200 and the outer wall of the inner shell 300 are separated to form an outer chamber 500. The inner walls of the inner shell 300 form an inner chamber 400. The nuclear magnetic resonance apparatus 100 is placed in the inner chamber 400. At least one plasma generator 900 is arranged on the bottom of the outer chamber 500. From a structural point of view, the lower layer of the double-chamber structure is a hydraulic buffer structure, and the outer chamber and the inner chamber are insulated (ceramic insulating rubber composite gasket is used to improve pressure resistance). In addition, the inner wall of the outer shell 200 and the outer wall of the inner shell 300 are separated to form an outer chamber 500. The outer chamber 500 has a space of 30 cm, which is equivalent to a suspended structure of the inner chamber.

[0040] like Figure 5 As shown, a plurality of buffer hooks 600 are arranged at the top of the inner wall of the outer shell 200, and a plurality of hanging ears 601 are arranged at the top of the outer wall of the inner shell 300, and the plurality of buffer hooks 600 and the plurality of hanging ears 601 match each other; buffer hooks 600 are arranged at the four corners of the inner wall of the outer shell 200, and hanging ears 601 are arranged at the four corners of the top of the outer wall of the inner shell 300, and the buffer hooks 600 and the hanging ears 601 form four corner hanging rings, and the buffer hooks 600 are made of buffer elastic material (such as polyurethane foam plastic), and the hanging ears 601 are fixed by an insulating hanging ring telescopic spring between the inner cavity and the outer cavity, thereby making the inner shell 300 and the outer shell 200 produce a pendulum effect during transportation, and by controlling the swing angle of the inner shell, the nuclear magnetic resonance instrument of the inner shell is kept stable. A plurality of shock absorbing components 700 are arranged at the bottom of the outer wall of the outer shell 200, for example, anti-vibration components 700 are arranged at the four corners of the bottom of the outer wall of the outer shell 200, such as Figure 5 As shown, the shock absorbing assembly 700 includes a pneumatic cylinder 701 disposed at the bottom of the outer shell 200, a spring 702 located on the outer wall of the pneumatic cylinder 701, and a support 703 at the bottom of the pneumatic cylinder 701. This allows the modified cabin to play a buffering role during the hoisting and placement process, reducing the movement of the nuclear magnetic resonance instrument and reducing the risk of collision.

[0041] The 100-nuclear magnetic resonance imaging apparatus includes a magnet 101, a rear bridge 102, a scanning bed 103, and an inspection ladder 104. The rear bridge 102 is arranged at the back of the magnet 101, the scanning bed 103 is arranged through the magnet 101 and the front end of the magnet, the inspection ladder 104 is arranged on the side wall of the magnet 101, and an emergency demagnetization device 105 is arranged inside the inner chamber 400 and near the magnet, so as to reduce the magnetic radiation of the magnet 101 in case of emergency or environmental changes.

[0042] The inner shell 300 includes an aluminum alloy frame and an inner wall. The structure of the inner shell 300 is, from the inside to the outside: graphite paint decoration, electrostatic interior materials, an aluminum alloy frame, copper wire coil winding and grounding, a copper wire insulation layer and a conductive cloth. The frame structure is supported by aluminum alloy, and iron magnetic materials cannot be used to prevent magnetic resonance, which causes a strong magnetic field to rupture or damage the cavity, resulting in the failure to achieve the magnetic shielding effect. Electrostatic interior materials (such as silicon steel) are traditional magnetic shielding interior materials. The copper wire coil is wound on the aluminum alloy frame, the copper wire coil is wound and grounded, and the copper wire is wrapped at a spacing of 20-25cm in the inner cavity. It is then covered with a copper wire insulation layer and finally wrapped with a conductive cloth, i.e. a shielding cloth. The conductive cloth is pasted on the outside of the copper wire insulation protective layer. It is a continuous whole and is grounded separately. It can be glued during the implementation process. Figure 3 As shown, the inner shell 300 wall is provided with a shielding door hole 301, a shielding window hole 302, a conductive plate hole 303, an air supply hole 304, a return air hole 305, a filter hole 306, a quench tube hole 307, a magnet inlet hole 308, an emergency exhaust hole 309, a lighting switch hole 310, a system cabinet hole 311, a system wiring hole 312 and a shielding small door hole 313. One end of the conductive plate passes through the conductive plate hole 303 and is connected to the inner chamber 400 where the magnet 101 is located, and the other end of the conductive plate is connected to the ISC cabinet, the single compressor and the 18kW cooling cabinet. One end of the quench tube passes through the quench tube hole 307 and is connected to the magnet 101. A radio frequency shielding waveguide is arranged on the outer wall of the quench tube in the inner chamber 400, and a 38mm insulating layer is used to wrap the quench tube. A support is arranged on the top of the quench tube and the inner wall of the inner shell 300, and the other end of the quench tube extends outdoors. An insect-proof net is arranged on the outdoor quench tube, and a 12.7mm mesh is used to prevent foreign objects such as rain, snow, and mice from entering. The structure of the outer shell 200 is sequentially from the inside to the outside: conductive cloth, fireproof insulation and thermal insulation layer, skeleton and aluminum veneer decorative layer. In the actual installation process, grounding is required. The inner shell 300 is an aluminum alloy skeleton, and the outer shell 200 is grounded on the skeleton, and the two are grounded separately. Through the multi-layer shielding materials of the inner shell 300 and the inner shell 200, the magnetic field of the magnet will not radiate out, thereby achieving the effect of magnetic shielding, controlling the magnetic radiation of the nuclear magnetic resonance instrument will not affect the external environment, and the external magnetic field will not affect the nuclear magnetic resonance instrument.

[0043] In one embodiment, if Figure 6, Figure 7 As shown, the plasma generator 900 includes a base 901, a generator 902 is arranged on the base 901, a wire 903 is connected to the rear end of the generator 902, a tip structure 904 is arranged at the front end of the generator 902, and the tip structure 904 is gold-plated, and at least one magnetic conductor 905 is arranged in front of the plasma generator 900. There are three magnetic conductors 905, and the magnetic conductor 905 at the end is provided with a tip structure 904; the inner wall of the outer shell 200 is provided with a plurality of inorganic flame retardant glasses 906. A plurality of inorganic flame retardant glasses 906 form a plurality of isolation cabins 907, and a vent hole 908 is provided in the inorganic flame retardant glass 906, and the magnetic conductor 905 is arranged in the isolation cabin 907. The rated power of the plasma generator 900 shall not exceed 3400w. The plasma generator 900 is provided with a variable resistance debugging module, which can adjust the intensity of the ion wind. During the debugging process and in emergency situations, the plasma wind blown by the plasma generator 900 can effectively block the magnetic flux lines. The installation of the plasma generator 900 is in a double-cavity structure with a 30cm space in the middle. The plasma generator 900 is fixed on the base of the gap between the outer cavity and the inner cavity. It can be seen that the metal tip structure 904 contacts the magnetic conductor 905 after the generator is powered on, thereby generating plasma. However, adding some conductive magnets of the same medium behind the conductor can also lead out the plasma. It is worth noting that the structure outside the last conductive magnet is like the generator, and what needs to appear is the tip structure. The material of the inorganic flame-retardant glass 906 is the same as the glass material of the ion generator in the Science and Technology Museum.

[0044] In one embodiment, if Figure 3 As shown, the outer shell 200 is provided with an air purification channel, which includes a vent 201 arranged on the outer shell 200 , and an air supply tunnel 304 and an air return tunnel 305 arranged on the inner shell 300 , and the height of the vent 205 is greater than the height of the air supply tunnel 304 and the air return tunnel 305 .

[0045] In one embodiment, if Figure 8 , Fig. 9 As shown, during the actual installation and application process, the cabin also includes an operation room 800, which is arranged outside the outer shell 200 and communicates with the nuclear magnetic resonance apparatus 100. The operation room 800 includes a control device 801 and a system cabinet 802. The system cabinet 802 is electrically connected to the nuclear magnetic resonance apparatus 100 through the system cabinet hole 311, and the control device 801 is electrically connected to the nuclear magnetic resonance apparatus 100 through the system wiring hole 312. Or other modules, such as a monitoring office module and an information module, are installed in the machine room in actual use in the later stage. During the actual installation process, necessary medical gas ports, drains, protective doors, etc. can be installed according to actual needs.

[0046] It should be noted that in actual use, all equipment in the cavity of the cabin is cooled by the Peltier effect. The cathode sheet is introduced into the base or floor where heat is easily generated, and it is ensured that it does not intersect with the external cavity.

[0047] The functional structure of the inner chamber 400, due to its special structure, specifically involves the following related technologies: (1) Air purification technology: use ultraviolet physical filtering and disinfection modules, one is placed in each corner to form convection, so that the air in the room circulates, thereby achieving the disinfection function. (2) Temperature control technology: the Peltier effect mentioned above is used as a temperature control technology, but the anti-static insulating floor or rubber layer needs to be laid on the ground (it can also be determined according to the actual use function). (3) Firefighting: physical traditional firefighting. (4) Dust reduction technology: high-voltage negative ion dust reduction technology, directly installed in the inner cavity near the grounding port, and away from the main medical equipment, the waveguide window is with the function of external purification gas or medical gas delivery, lighting, insulated rubber wire pipes, etc. are all designed according to existing technologies, but it is worth noting that the installation of filters needs to be installed outside.

[0048] The square cabin of the present invention can be applied in the fields of machinery, medical treatment, biochemistry, information, etc., and the square cabin is aimed at the medical and health cause, and is used as a medical infrastructure in remote areas, emergency events and other special areas. The main considerations in the process are medical quality factors (demagnetization, noise reduction, constant temperature, de-electricity, sterilization, negative pressure, etc.), while ensuring the basic medical functions, and the project is easy to construct and install, and has little environmental harm.

[0049] During transportation, in the inner chamber 400, the magnet 101 is connected to the Dewar tank through a liquid nitrogen transmission tube, and the magnet plus liquid nitrogen is inserted into the liquid nitrogen transmission tube through the Dewar tank. The inner chamber 400 meets the requirements for Dewar tank intubation, and a movable ceiling can be made. The movable ceiling (at least 610mm*610mm) is opened for intubation. The inner chamber 400 cannot meet the requirements for Dewar tank intubation. The Dewar tank intubation is performed outdoors in an area that requires a high degree of satisfaction. 250L Dewar tank: The required height for intubation is 3442mm, the height after intubation is 2007mm, and the minimum width is 950mm. 500L Dewar tank: The required height for intubation is 3505mm, the height after intubation is 2007mm, and the minimum width is 1200mm.
