Mobile MRI examination device

The present invention proposes a mobile nuclear magnetic resonance examination device, as shown in Figures 1 to 3, which includes a nuclear magnetic resonance main body 11, a shielding shell 12 and a moving wheel 13; the nuclear magnetic resonance main body 11 is arranged in the shielding shell 12, the shielding shell 12 is provided with an opening 121, and an open conductive structure is provided around the opening 121, and the open conductive structure is used to make the shielding shell 12 conductively connected to the external shielding component; the moving wheel 13 is installed at the bottom of the shielding shell 12 to drive the mobile nuclear magnetic resonance examination device 1 to move.

Based on the above structure, the present invention provides a mobile nuclear magnetic resonance examination device, which realizes the mobility of the mobile nuclear magnetic resonance examination device 1 by arranging the nuclear magnetic resonance main body 11 in the shielding shell 12, and the shielding shell 12 is driven to move by the moving wheel 13; the shielding shell 12 has an opening 121, and the shielding shell 12 forms an electromagnetic shielding structure except the opening 121. When the mobile nuclear magnetic resonance examination device 1 is conductively connected to the shielding component for accommodating the patient through the opening 121, the mobile nuclear magnetic resonance examination device 1 and the shielding component for accommodating the patient together form a closed electromagnetic shielding space. In this way, the patient and the nuclear magnetic resonance main body 11 are both wrapped in the electromagnetic shielding space to prevent external interference from entering the nuclear magnetic resonance main body 11 to interfere with the examination results. This kind of mobile nuclear magnetic resonance examination device is conducive to the realization of a mobile nuclear magnetic resonance examination system.

The open conductive structure referred to in the present application may be an external conductive metal ring, which surrounds the opening 121 and is conductively connected to the shielding shell 12; the open conductive structure may also be a conductive member extending outward from the shielding shell 12 or exposed, which surrounds the opening 121. Of course, the open conductive structure may take various forms, as long as the conductive connection can be achieved, so that the mobile nuclear magnetic resonance examination device and the shielding component for accommodating the patient can form a closed electromagnetic shielding space.

The above-mentioned shielding components for accommodating patients can have various structural forms, and the preferred structural forms will be described in detail below. Of course, in addition to the mobile nuclear magnetic resonance examination shielding cabin 2 provided below, there are also many structural forms of shielding components for accommodating patients, which can also be used in conjunction with the mobile nuclear magnetic resonance examination device provided by the present invention. As long as they can be electrically connected to the open conductive structure on the mobile nuclear magnetic resonance examination device and together form a closed electromagnetic shielding space, the present invention can be realized.

In this embodiment, the shielding shell 12 includes a shielding frame 122 and a shielding wall plate 123. The shielding wall plate 123 is embedded between the shielding frame 122, and the edge of the shielding wall plate 123 is conductively connected to the shielding frame 122. Preferably, a flexible conductive material 17 is provided between the edge of the shielding wall plate 123 and the joint surface of the shielding frame 122. The flexible conductive material 17 is to ensure that the gap between the edge of the shielding wall plate 123 and the joint surface of the shielding frame 122 is filled with the flexible conductive material 17, so as to ensure a better shielding effect.

In this embodiment, an observation window 14 is provided on at least one shielding wall plate 123 located on the side of the shielding shell 12. The doctor can observe the patient's condition through the observation window 14. The observation window 14 here is also an observation window capable of shielding electromagnetic radiation.

In this embodiment, a data interface 15 is provided on the shielding wall plate 123 of the shielding shell 12, and the data interface 15 is communicatively connected with the NMR body 11. The data interface 15 is used to realize signal transmission between the NMR body 11 and an external controller.

In this embodiment, a lifting ring 16 is installed on the upper surface of the shielding wall plate 123 at the top of the shielding shell 12. In this way, when the mobile nuclear magnetic resonance examination device needs to be lifted to a certain level, it can be lifted by the lifting ring 16.

Mobile MRI Inspection System

The present invention also provides a mobile nuclear magnetic resonance examination system, as shown in Figures 1 to 6, which includes the above-mentioned mobile nuclear magnetic resonance examination device 1, and also includes a mobile nuclear magnetic resonance examination shielding cabin 2; the mobile nuclear magnetic resonance examination shielding cabin 2 includes a cabin body 21 and a mobile bracket 22, and the mobile bracket 22 is installed under the cabin body 21 to drive the cabin body 21 to move; the cabin body 21 is provided with a port 211, and the port 211 of the cabin body 21 can be connected with the opening 121 of the shielding shell 12, and a port conductive structure is provided around the port 211; when the port 211 of the cabin body 21 is connected with the opening 121 of the shielding shell 12, the port conductive structure is conductively connected to the opening conductive structure, so that the cabin body 21 and the shielding shell 12 together constitute a closed electromagnetic shielding space.

Based on the above structure, when necessary, the mobile MRI examination device 1 and the mobile MRI examination shielding cabin 2 can be moved together to the required place, for example, directly to the side of the patient's bed, and then the patient is transferred to the cabin body 21 of the mobile MRI examination shielding cabin 2, and then the mobile MRI examination device 1 is connected to the mobile MRI examination shielding cabin 2. In this way, the patient and the MRI body 11 are both wrapped in a closed electromagnetic shielding space to prevent external interference from entering, and the patient can be examined by starting the MRI body 11.

The port conductive structure referred to in the present application can be an additional conductive metal ring, which surrounds the port 211 and is conductively connected to the cabin 21; the port conductive structure can also be a conductive part that extends outward or is exposed from the cabin 21, and the conductive part surrounds the port. For example, when the shielding plate is composed of a transparent plate and a shielding net sandwiched between the transparent plates, part of the shielding net can be arranged to extend outward or be exposed. These shielding nets that extend outward or are exposed are the conductive parts, and these shielding nets that extend outward or are exposed form a closed state to constitute the port conductive structure. Of course, in addition to the above-mentioned structural forms, there are other structural forms of port conductive structures, and similar replacements also fall within the scope of protection of the present invention. Subsequently, the conductive metal ring on the cabin 21 is conductively connected to the conductive metal ring on the shielding shell 12, so that the cabin 21 and the shielding shell 12 together form a closed electromagnetic shielding space.

In this embodiment, the cabin 21 includes a plurality of shielding plates, which enclose a receiving cavity for receiving the patient, and the connected shielding plates are conductively connected. At least some of the shielding plates are transparent shielding plates, which include transparent plates 212 and shielding nets 213 sandwiched between the transparent plates 212, that is, some of the shielding plates may be transparent shielding plates, or all of the shielding plates may be transparent shielding plates. When the shielding plates are made into transparent shielding plates of the above structure, the doctor can see the patient's situation in the cabin 21 through the transparent shielding plates. Preferably, the transparent plate 212 may be made of glass plates, organic glass plates or PE plates, and the shielding net 213 may be made of stainless steel nets or copper nets. Further preferably, a structure in which the shielding net 213 is sandwiched between multiple layers of transparent plates 212 may be used to increase the shielding effect. To facilitate assembly, the area of the shielding net 213 can be made larger than the area of the transparent plate 212, so that part of the shielding net 213 is exposed outside the transparent plate 212. These exposed shielding nets 213 can be used for conductive connection with the conductive strips 214 described below, and can also be used for conductive connection with shielding nets 213 on other shielding plates.

In this embodiment, an exposed conductive strip 214 is provided at the edge of the transparent shielding plate, and the conductive strip 214 is electrically connected to the shielding mesh 213 in the transparent shielding plate, and the connected transparent shielding plates are conductively connected through the conductive strip 214. Based on the above structure, when two transparent shielding plates are connected, the conductive strips 214 on the two transparent shielding plates are conductively connected to achieve electromagnetic shielding between the connected transparent shielding plates.

In this embodiment, the mobile support 22 includes a scissor lift 221, a universal wheel 222 arranged at the bottom of the scissor lift 221, and a load-bearing bed surface 223 arranged at the top of the scissor lift 221. The load-bearing bed surface 223 carries the cabin 21, a patient support plate 23 is arranged in the cabin 21, and a locking structure is arranged on the universal wheel 222. Based on the above structure, after the mobile nuclear magnetic resonance examination shielding cabin 2 is moved to the bed of a patient who is inconvenient to transfer, the universal wheel 222 is locked, part of the shielding plate is disassembled or turned down, and the height of the cabin 21 is adjusted to the same height as the patient's bed through the scissor lift 221, and then the patient can be easily transferred to the patient support plate 23. Unlock the universal wheel 222, then move the mobile MRI examination shielding cabin 2 to the vicinity of the mobile MRI examination device 1 and adjust the scissor lift 221. After adjusting the position of the patient, reinstall the shielding plate, and connect the cabin body 21 to the shielding shell 12 to form a closed electromagnetic shielding space. The MRI body 11 and the patient are both wrapped in the closed electromagnetic shielding space to shield external interference, and the examination can begin.

The flexible conductive material 17 mentioned in the present application may be a conductive cloth or a soft copper mesh.

The conductive connection mentioned in this application refers to the connection of the shielding components in terms of shielding effect, and does not mean that electricity is required during subsequent use.

In the absence of conflict, the above embodiments and features in the embodiments can be combined with each other.

Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
