Description

Technical Field

[0001] The utility model relates to the technical field of MRI shielding rooms, and more specifically, to a replacement sound-insulated MRI shielding room with an internal duplex structure. Background Art

[0002] An MRI shielded room is a room used to protect the surrounding environment from electromagnetic radiation interference emitted by magnetic resonance imaging equipment. The design and construction of an MRI shielded room must strictly follow relevant standards and specifications to ensure its shielding effect and safety performance.

[0003] After searching, a Chinese patent with application number CN202122619575.X discloses an environmentally friendly assembled MRI shielding room with an aluminum structure. Most of the current MRI shielding rooms use wooden planks as keels. The wooden planks themselves have the characteristics of thermal expansion and contraction. Overheating or overcooling can easily cause the wooden planks to deform. The MRI shielding room is prone to gaps, resulting in unstable shielding effectiveness. People who work outside the MRI shielding room for a long time are susceptible to radiation, which is inconvenient to use. The lower shelf plate and the upper shelf plate are connected on both sides by a middle plate, and the top plate fixedly installed in the middle of the top of the lower shelf plate is inserted into the inside of the groove, the rack matches the bottom tooth groove, and the shape formed by the groove and the top slot matches the middle plate, and the upper half of the middle plate and the bottom slot are threadedly connected by bolts, and the lower half of the middle plate and the top slot are threadedly connected by threads, which is convenient for splicing between the lower shelf plate and the upper shelf plate.

[0004] The MRI shielding room has limited sound insulation effect during use. Its internal space design is relatively conventional, which results in the sound insulation effect not being fully exerted. At the same time, it is inconvenient to replace the protective structure of the MRI scanner in time when it is damaged or the protective effect is reduced. Therefore, a replacement soundproof MRI shielding room with an internal duplex structure is proposed. Utility Model Content
