[0045] In this document, "schematic" means "serving as an example, instance, or illustration", and any illustration or implementation manner described as "schematic" in this document should not be construed as a more preferred or advantageous technical solution.

[0046] To simplify the drawings, only the parts related to the utility model are schematically shown in each drawing, and they do not represent the actual structure of the product.

[0047] Figure 1 Is a flowchart of a schematic implementation manner of a medical treatment vehicle for carrying a magnetic resonance device. Refer to Figure 1 , the magnetic resonance device includes a magnetic resonance main unit 31 and a scanning bed 32. The medical treatment vehicle for carrying the magnetic resonance device includes a non-magnetic stainless steel frame 10 and a shelter 20. The non-magnetic stainless steel frame 10 is used to install the suspension system and carry the shelter 20.

[0048] The interior of the shelter 20 is used to accommodate the magnetic resonance main unit 31 and the scanning bed 32. Figure 2 and Figure 3 Is a schematic structural diagram of the shelter. Refer toFigure 2 and Figure 3 , in a schematic embodiment, the six cabin plates include a carriage bottom plate 21, two carriage side plates 22, a carriage rear plate 23, a carriage front plate 24, and a carriage top plate 25. The carriage bottom plate 21 is used to connect to the non-magnetic stainless steel frame 10. The two carriage side plates 22 are parallel to each other and perpendicular to the width direction W of the non-magnetic stainless steel frame 10. The carriage rear plate 23 is perpendicular to the length direction L of the non-magnetic stainless steel frame 10. The carriage front plate 24 is parallel to the carriage rear plate 23, and the distance between the carriage front plate 24 and the carriage rear plate 23 is greater than the distance between the two carriage side plates 22. The carriage top plate 25 is parallel to the carriage bottom plate 21.

[0049] Figure 4 is a partial cross-sectional view of the carriage bottom plate. Referring to Figure 4 , taking the carriage bottom plate 21 as an example, each cabin plate includes two composite material layers 211, an aluminum alloy frame 212, an insulating material layer 213, a magnetic shielding sheet 214, and a radio frequency shielding plate 215.

[0050] In a schematic embodiment, the two composite material layers 211 are glass steel plates, and the two composite material layers 211 are parallel and arranged at intervals. A flame-retardant heat-insulating filler 217 is filled between the two composite material layers 211. The heat-insulating filler 217 adopts a B2-level flame-retardant rating, and the thermal conductivity is less than 0.03 W / (m*k). The aluminum alloy frame 212 is arranged between the two composite material layers 211 and plays a role in supporting and strengthening. The insulating material layer 213 is arranged parallel between the two composite material layers 211. The magnetic shielding sheet 214 is a silicon steel sheet and is arranged parallel between the two composite material layers 211 to achieve magnetic shielding. The radio frequency shielding plate 215 is a copper foil plate and is arranged parallel between the two composite material layers 211 to achieve radio frequency shielding. The copper foil plate reserves a welding allowance and is laminated and welded at the splicing joints of each cabin plate. However, it is not limited to this. In other schematic embodiments, the composite material layer 211, the magnetic shielding sheet 214, and the radio frequency shielding plate 215 can be replaced by other structures that can achieve the same functions.

[0051] The diagnostic and treatment vehicle for carrying a magnetic resonance device provided by the present utility model adopts a non-magnetic stainless steel frame to carry a cabin made up of spliced multi-layer shielded plates. There is a non-magnetized design under the magnetic resonance host, and a common air suspension system can meet the requirements of magnetic static interference, without the need for a customized non-magnetic suspension system, reducing the manufacturing cost.

[0052] In a schematic embodiment, referring to Figure 2 and Figure 3 , the cabin 20 further includes several angle aluminum profiles 26. The several angle aluminum profiles 26 cover the splicing seams of the six cabin plates from the outside, and the angle aluminum profiles 26 are connected and fixed at the ends, thereby enhancing the overall stiffness of the cabin 20 when it is lifted.

[0053] In a schematic embodiment, referring to Figure 2 , the mobile medical cabin 20 further includes several aluminum crossbeams 27 and several aluminum longitudinal beams 28. Each aluminum crossbeam 27 is fixed to the outer surface of the carriage floor 21 along the width direction W of the non-magnetic stainless steel vehicle frame 10 and connects the angle aluminum profiles 26 on both sides of the carriage floor 21. The several aluminum crossbeams 27 are arranged at intervals along the length direction L of the non-magnetic stainless steel vehicle frame 10. Each aluminum longitudinal beam 28 is fixed to the bottom of the several aluminum crossbeams 27 along the length direction L of the non-magnetic stainless steel vehicle frame 10. The several aluminum longitudinal beams 28 are arranged at intervals along the width direction W of the non-magnetic stainless steel vehicle frame 10. Thereby enhancing the overall stiffness of the mobile medical cabin 20.

[0054] In a schematic embodiment, referring to Figure 4 , the carriage floor 21 further includes several T-shaped aluminum materials 216. The several T-shaped aluminum materials 216 are fixed to the aluminum alloy frame 212 and protrude from the inner surface of the carriage floor 21. The several T-shaped aluminum materials 216 are used to fix the magnetic resonance main unit 31 and the examination table 32.

[0055] In a schematic embodiment, the thickness of the carriage floor 21 is 40 mm, the thickness of the rear carriage panel 23 and the front carriage panel 24 is 50 mm, and the thickness of the two carriage side panels 22 and the carriage top panel 25 is 55 mm. The reason for the different thicknesses of the cabin panels is that the thicknesses of the magnetic shielding sheets 214 in the rear carriage panel 23 and the front carriage panel 24 are equal and greater than the thickness of the magnetic shielding sheet 214 in the carriage floor 21. The thicknesses of the magnetic shielding sheets 214 in the two carriage side panels 22 and the carriage top panel 25 are equal and greater than the thickness of the magnetic shielding sheet 214 in the rear carriage panel 23 and the front carriage panel 24. Usually, the magnetic resonance main unit 31 and the examination table 32 are arranged along the length direction L of the non-magnetic stainless steel vehicle frame 10. Magnetic shielding sheets 214 with different thicknesses are respectively provided on each cabin panel to ensure that the 0.5 mT magnetic force lines of the magnet do not exceed the mobile medical cabin 20, ensuring the inaccessibility of people outside the vehicle while reducing the weight and manufacturing cost.

[0056] The magnetic shielding sheets 214 in the carriage floor 21, the carriage side panels 22, the rear carriage panel 23 and the front carriage panel 24 cover the entire carriage floor 21, the carriage side panels 22, the rear carriage panel 23 and the front carriage panel 24. The magnetic shielding sheet 214 in the carriage floor 21 covers the part where the carriage floor 21 is spliced with the two carriage side panels 22.

Referring to Figure 5, in which other structures of the cabin floor except the magnetic shielding sheet 214 are hidden. In the illustrative embodiment, the magnetic shielding sheets 214 in the carriage floor 21, carriage side plates 22, carriage rear plate 23 and carriage front plate 24 cover the entire carriage floor 21, carriage side plates 22, carriage rear plate 23 and carriage front plate 24, and the magnetic shielding sheet 214 in the carriage floor 21 covers the part where the carriage floor 21 is spliced with the two carriage side plates 22. Thereby, while ensuring the inaccessibility to personnel outside the vehicle, the weight and manufacturing cost are reduced.

[0058] Referring to Figure 1 , the present invention also provides a vehicle-mounted magnetic resonance system, which includes a magnetic resonance device and a medical treatment vehicle for carrying the magnetic resonance device as described above. The magnetic resonance device includes a magnetic resonance main unit 31 and a scanning bed 32. The magnetic resonance main unit 31 and the scanning bed 32 are fixed inside the shelter 20.

[0059] The vehicle-mounted magnetic resonance system provided by the present utility model uses a non-magnetic stainless steel frame 10 to carry the shelter 20 formed by splicing multi-layer shielded cabin plates. There is a non-magnetized design under the magnetic resonance main unit, and ordinary air suspension can meet the requirements of magnetic static interference, without the need for customized magnetic air suspension, reducing the manufacturing cost.
