Description

Technical Field

[0001] The utility model relates to the field of nuclear medicine examination, in particular to a conduction cabinet for a nuclear medicine PET-MR examination room. Background Art

[0002] In nuclear medicine, the effect of MRI examination is to stimulate hydrogen protons in the body through magnetic field, and obtain images after computer processing according to different durations. Since no radiation is generated during the whole process, only signal shielding is required when constructing the MRI examination room. In terms of space, the MRI examination room includes not only the large room where the MRI detector is placed (usually called the examination room), but also a small room for circuit control required by the detector and other equipment. There is a conduction port for transmitting signals between the two rooms, and a conduction plate is set at the conduction port. At present, the purpose of magnetic shielding of MRI detectors is often achieved by magnetically shielding the two rooms at the same time. For the sake of aesthetic design, a wall cabinet covering the conduction plate will be set on one side of the large room. If the conduction plate needs to be inspected, the wall cabinet is directly opened, and if the control circuit needs to be inspected, the small room is directly entered.

[0003] PET-MR is a large-scale functional metabolic and molecular imaging diagnostic equipment that is an integrated combination of positron emission tomography (PET) and magnetic resonance imaging (MR). Compared with MRI, PET-MR is a more advanced and accurate detection method. In addition to being used for examinations of ordinary patients, it is also often used for examinations of patients injected with radioactive agents. Therefore, based on both detection and application considerations, when constructing a PET-MR examination room, not only signal shielding but also radiation protection is required. The current protection idea is usually based on the MRI magnetic shielding trajectory (overall protection of the two rooms). Such protection has a defect, that is, no matter whether it is a major overhaul or a minor overhaul, in order to avoid radiation exposure to maintenance personnel, the entire equipment needs to be shut down in advance, while some overhauls do not necessarily have to be carried out under shutdown. The shutdown process is lossy for both hospitals and patients. Therefore, the present application has developed a conduction cabinet for a PET-MR examination room based on nuclear medicine, which can better solve the above problems. Utility Model Content

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0030] like Figure 1-3 As shown, in this embodiment, the conduction cabinet for a nuclear medicine PET-MR examination room includes a keel frame 1, a lead protective layer 2 and an outer decorative layer 3;

[0031] The keel frame 1 is arranged at a corner of the inspection room so that its adjacent two sides are fixed against the wall, and the other two sides are respectively arranged as the front side and the side. The keel frame 1 is divided into an upper space 11 and a lower space 12. The lower space 12 is divided into a front area 121 and a rear area 122 in the front and rear. The rear side of the keel frame 1 corresponding to the rear area 122 is provided with an inspection port 123 cooperating with the conductive plate. The keel frame corresponding to the front area 121 is respectively provided with an inlet and outlet 124 in the front and rear. The front area 121 forms a first front area 1211 close to the side and a second front area 1212 away from the side on both sides of the inlet and outlet 124, and forms a hoisting area 1213 above the inlet and outlet.

[0032] The lead protection layer 2 includes a lead protection door 21 and a lead sheet layer arranged on the keel frame 1. The lead protection door 21 includes a plurality of sliding door panels arranged in sequence front and back. The plurality of sliding door panels are arranged between the two inlets and outlets 124. When the plurality of sliding door panels are pulled apart in sequence, they can cooperate with the lead sheet layer to isolate the radiation between the rear area and the inspection room. Among the plurality of sliding door panels, the sliding door panels located at the front side are close to the side after being pulled apart, and the sliding door panels located at the rear side are far away from the side, so that the door gaps of adjacent sliding door panels are away from the center direction of the inspection room, so as to achieve a better protection effect.

[0033] The outer decorative layer 3 includes decorative panels ( Figure 3 In order to present the first lead plate, the side decorative plate is not installed yet). In addition, Figure 4 As shown, decorative panels may also be provided on the inner walls of the rear area and the front area as required to form an inner decorative layer 4.

[0034] Regarding the protective layer, based on the considerations of protective effect and setting cost, the following settings can be made: the lead plate layer includes a first lead plate 22, a second lead plate 23, a third lead plate 24, a fourth lead plate 24 and a fifth lead plate 26, the first lead plate 22 is arranged on the side of the keel frame corresponding to the lower space 12, the second lead plate 23 is arranged on the front side of the keel frame corresponding to the first front area 1211 and the lifting area 1213, the third lead plate 24 is arranged on the keel frame 1 on the rear side of the second front area, the fourth lead plate 25 is arranged on the keel frame 1 at the bottom of the upper space or the top of the lower space, the fifth lead plate 26 is arranged on the front side of the keel frame corresponding to the bottom of the inlet and outlet, wherein the upper ends of the first lead plate 22 and the second lead plate 23 are arranged higher than the top of the fourth lead plate 25.

[0035] Next, the advantages of the above-mentioned conduction cabinet will be described in detail. The examination room mentioned in the description specifically refers to the room where the examination equipment is placed. In the hospital, the PET-MR examination equipment is generally placed in the center of the examination room, so the center is the radiation source. For the radiation source, the conduction cabinet of the present application realizes efficient radiation protection in the lateral direction for the rear area through the first lead plate 22, the second lead plate 23, multiple sliding door panels, the third lead plate 24, and the fifth lead plate 26 in sequence. Specifically, since the conduction cabinet is set in a corner of the examination room, the gaps between the multiple sliding door panels and between the second lead plate 23 and the third lead plate 24 are all in the direction away from the radiation source, which will effectively prevent the rays from entering the rear area 122 through the gaps. In addition, since the walls of the inspection room are protected by lead plates, combined with the side protection formed by the present application and the top protection of the fourth lead plate 25, the radiation source's rays can be effectively isolated from entering the rear area, which is equivalent to forming a safe area for inspection personnel to enter. In this way, for some maintenance situations that do not require shutdown, the conduction plate and the circuits and other structures in the room behind the conduction plate can be inspected, thereby saving more time for examining patients.

[0036] In addition to the above advantages, the conduction cabinet of the present application also has the advantages of saving cost and space. Specifically, the use of multiple sliding door panels can save space as much as possible, so as to better realize the setting of the door gap away from the radiation source; the conduction cabinet is set in a corner, and the lower space is divided out for protection, which can greatly save lead protection materials.

[0037] In one specific embodiment, Figure 4-5As shown, in order to arrange the lines connecting the inspection room and the conductive plate, a threading hole 125 is also provided at the top of the keel frame 1 corresponding to the rear area 122, and a lead protective cover 27 covering the threading hole 125 is provided in the upper space 11, and a threading hole is provided on the rear side of the lead protective cover 27. Such an arrangement can better shield radiation, and the lines passing through the rear area can be arranged along the wall of the inspection room corresponding to the upper space, and other required equipment can also be arranged in the upper space as needed.

[0038] In one specific embodiment, since the conductive plate will generate heat during use, lead shutters may be provided on the sliding door panel to accelerate the heat dissipation. Figure 3 shown.

[0039] In one specific embodiment, at least a portion of the sliding door panel can be embedded in the second front area 1212 after being opened.

[0040] In one specific embodiment, it is preferred that the lead protection door is provided with three sliding door panels.

[0041] In one of the specific embodiments, the upper end of the keel frame 1 extends to be fixed to the top keel of the inspection room, the firmness of the overall structure is greatly increased, and the upper space formed is convenient for accommodating other required equipment, such as a cooling fan, etc.

[0042] In one of the specific embodiments, the sliding door panel is hoisted and installed in the hoisting area through a hoisting component, and the hoisting component can specifically adopt a track and a hoisting wheel structure.

[0043] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0044] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
