Description

Technical Field

[0001] The utility model relates to the technical field of magnetic resonance, and more specifically to a split-type shielding cabin. Background Art

[0002] When the MRI detection equipment is detecting and scanning, the MRI imaging signal is very susceptible to interference from external electromagnetic signals. Therefore, the MRI system must be installed in an electromagnetic shielding environment to shield external electromagnetic interference in order to achieve an imaging effect that meets clinical needs. Existing MRI systems are usually fixed installation forms and need to be installed in a MRI shielding room. The patient needs to move to the shielding room and undergo MRI detection in the shielding room. It is very inconvenient for critically ill patients or patients who are not easy to walk or move to go to the shielding room for detection.

[0003] Although some MRI detection equipment currently realizes the integrated design of shielding cabin and MRI, the shielding cover installed on the scanning bed is mostly a push-pull sliding structure, and the top of the scanning bed cannot be fully opened. It is very inconvenient for patients to get on and off the scanning bed during the test, especially for patients who cannot move independently. It will be more difficult to transfer them to the scanning bed. In addition, since the top of the scanning bed cannot be fully opened, when emergency treatment is required for the patient, the shielding cover will also affect the emergency treatment operation.

[0034] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by the same or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0035] Embodiment 1:

[0036] See also Figures 1 to 4 The present embodiment provides a split shielding cabin, which includes a fixed shielding cover 1 and two flip shielding covers 2; wherein the fixed shielding cover 1 is arranged on a support frame 4, and the support frame 4 is arranged on one side of the main shielding cover 3; the two flip shielding covers 2 can be opened and closed on the fixed shielding cover 1, and the two flip shielding covers 2 are movably connected to the support frame 4 through at least two groups of connecting rod assemblies 6 respectively; the opening and closing directions of the two flip shielding covers 2 are arranged along the width direction of the fixed shielding cover 1; when the two flip shielding covers 2 are opened, the two flip shielding covers 2 are respectively moved to the two sides of the width direction of the fixed shielding cover 1.

[0037] Specifically, the magnetic resonance system is arranged in the main shielding cover 3, and the magnetic resonance system is used to perform magnetic resonance detection on the patient. The fixed shielding cover 1 is used to place the scanning bed 5, and the scanning bed 5 is slidably arranged in the fixed shielding cover 1. By pushing the scanning bed 5 to move, the scanning bed 5 and the patient lying on it can be sent into the magnetic resonance system in the main shielding cover 3 for magnetic resonance detection. The fixed shielding cover 1 is fixedly arranged on the upper part of the support frame 4, and the support frame 4 plays a supporting and fixing role; the bottom of the support frame 4 is provided with rollers. After the combination formed by the support frame 4, the flip shielding cover 2, the fixed shielding cover 1 and the scanning bed 5 is separated from the magnetic resonance body, the flip shielding cover 2 is opened to make the top of the scanning bed 5 completely open, so that it can be used for the transportation of patients; the patient lies on the scanning bed 5, and the combination can be immediately imaged and scanned after docking with the magnetic resonance body, thereby reducing the number of times the patient is transported. The fixed shielding cover 1, the flip shielding cover 2 and the main shielding cover 3 are all made of electromagnetic shielding materials, for example, the fixed shielding cover 1, the flip shielding cover 2 and the main shielding cover 3 are made of metal materials such as beryllium copper and stainless steel; of course, a certain proportion of conductive fillers can be filled in the non-conductive substrate to make the material conductive and used as an electromagnetic shielding material. In this embodiment, each of the flip shielding covers 2 is movably connected to the support frame 4 through two sets of connecting rod assemblies 6, and the two sets of connecting rod assemblies 6 are respectively arranged at both ends of the length direction of the support frame 4.

[0038] See also Figure 1 and Figure 2, the connecting rod assembly 6 includes an upper connecting rod 61 and a lower connecting rod 62. The first ends of the upper connecting rod 61 and the lower connecting rod 62 are respectively rotatably connected to the support frame 4, and the second ends of the upper connecting rod 61 and the lower connecting rod 62 are respectively rotatably connected to the flipping shielding cover 2; the support frame 4, the upper connecting rod 61, the flipping shielding cover 2 and the lower connecting rod 62 form a quadrilateral connecting rod mechanism. Specifically, the upper part of the support frame 4 is in a "U" - shaped structure, and the fixed shielding cover 1 is arranged in the "U" - shaped structure at the upper part of the support frame 4; the first ends of the upper connecting rod 61 and the lower connecting rod 62 are respectively rotatably connected to one side of the "U" - shaped structure at the upper part of the support frame 4, and the first end of the upper connecting rod 61 is located above the first end of the lower connecting rod 62. Similarly, the second end of the upper connecting rod 61 is located above the second end of the lower connecting rod 62. The quadrilateral connecting rod mechanism formed by the support frame 4, the upper connecting rod 61, the flipping shielding cover 2 and the lower connecting rod 62 enables the flipping shielding cover 2 to move to a position below the outside of the fixed shielding cover 1 under the action of the connecting rod when the flipping shielding cover 2 is opened. As Figure 3 is a schematic structural diagram of the closed state of the two flipping shielding covers 2 in this embodiment, Figure 4 is a schematic structural diagram of the opened state of the two flipping shielding covers 2 in this embodiment.

[0039] In this embodiment, the fixed shielding cover 1 is a trough - shaped structure with an open top. The fixed shielding cover 1 includes a horizontal bottom plate and two arc - shaped side plates. The two arc - shaped side plates are symmetrically arranged at both ends in the width direction of the horizontal bottom plate, and the axes of the two arc - shaped side plates coincide. Extension plates extending outward are respectively arranged at the tops of the two arc - shaped side plates. When the flipping shielding cover 2 is closed, the lower end of the flipping shielding cover 2 abuts against the extension plate at the top of the arc - shaped side plate. In this embodiment, the flipping shielding cover 2 is in an arc - shaped structure, and the upper connecting rod 61 and the lower connecting rod 62 are also in arc - shaped structures. In other alternative embodiments, the fixed shielding cover 1 and the flipping shielding cover 2 can also be of other shapes.

[0040] In order to enable the flipping shielding cover 2 to play a better shielding role when in the closed state, a first shielding gasket 71 is arranged at the side edges where the two flipping shielding covers 2 are butted; a second shielding gasket 72 is arranged at the side edges where each flipping shielding cover 2 is butted with the fixed shielding cover 1. Specifically, in this embodiment, a first shielding gasket 71 is arranged on the upper side edge of one of the flipping shielding covers 2, and the upper side edge of the other flipping shielding cover 2 is not provided with a first shielding gasket 71; the lower side edges of the two flipping shielding covers 2 are both provided with second shielding gaskets 72. The first shielding gasket 71 and the second shielding gasket 72 can be made of conductive foam, and the first shielding gasket 71 and the second shielding gasket 72 can be fixedly bonded to the flipping shielding cover 2 through an adhesive. It can be understood that the second shielding gasket 72 can also be arranged on the two side edges of the fixed shielding cover 1.

[0041] A blocking plate (not shown in the figure) is provided at the end of the fixed shielding cover 1 away from the main shielding cover 3. The blocking plate is used to block the end of the fixed shielding cover 1 away from the main shielding cover 3, and to block the end of the flip shielding cover 2 away from the main shielding cover 3 when the two flip shielding covers 2 are in a closed state, so as to achieve electromagnetic shielding. In specific implementation, the blocking plate can be a circular plate, the lower end of the blocking plate is fixedly arranged at the end of the fixed shielding cover 1, and the upper end of the blocking plate extends out of the fixed shielding cover 1, so as to block and shield the electromagnetic signal at the end of the flip shielding cover 2 in the closed state. A docking shielding structure 9 (not shown in the figure) is also provided on the outside of the input port of the main shielding cover 3 and on the blocking plate. The docking shielding structure 9 is used to electromagnetically shield the connection between the flip shielding cover 2 and the main shielding cover 3, and the connection between the flip shielding cover 2 and the blocking plate when the flip shielding cover 2 is closed. In specific implementation, the docking shielding structure 9 can be a section of arc plate, and a conductive foam or shielding spring is arranged on the outer side of the arc plate. When the flip shielding cover 2 is closed, the inner side of the flip shielding cover 2 is pressed on the conductive foam or shielding spring on the outer side of the arc plate, thereby realizing electromagnetic shielding.

[0042] Furthermore, a locking mechanism is also provided on the flip shielding cover 2, and the locking mechanism is used to lock and fix the two flip shielding covers 2 when the two flip shielding covers 2 are in a closed state. In specific implementation, the locking mechanism can adopt a snap lock, and at least two snap locks are provided along the length direction of the flip shielding cover 2. The fixing plate of the snap lock is provided on one of the flip shielding covers 2, and the connecting hook body of the snap lock is provided on the other flip shielding cover 2. The locking mechanism can also adopt a magnetic locking structure or any other locking structure, and it can only realize the locking and fixing of the two flip shielding covers 2 in a closed state, and this embodiment does not impose any limitation on this. The outer shell of the flip shielding cover 2 can also be provided with a handle, so that the flip shielding cover 2 can be opened and closed conveniently by holding the handle.

[0043] Embodiment 2:

[0044] like Figures 5 to 7 As shown, the split shielding cabin in this embodiment is different from that in the first embodiment in that:

[0045] A driven wheel 81 is fixedly disposed at the first end of the lower connecting rod 62, and the driven wheel 81 is rotatably connected to the support frame 4. Two driving wheels 82 are also rotatably disposed on the support frame 4, and the two driving wheels 82 are respectively connected to the driven wheels 81 on the corresponding side. The driven wheel 81 can be driven to rotate by rotating the driving wheel 82, thereby driving the flip shielding cover 2 to perform the opening and closing actions.

[0046] In this embodiment, the driving wheel 82 and the driven wheel 81 are both pulleys, and each of the driving wheels 82 is respectively connected to the driven wheel 81 on the corresponding side through the first belt 83. In order to facilitate the rotation of the driving wheel 82, a hand crank is provided on the driving wheel 82, or the driving wheel 82 is connected to a driving motor, and the driving connection is fixed on the support frame 4. Specifically, when a hand crank is provided on the driving wheel 82, the hand crank extends out of the outside of the support frame 4, and the staff can open or close the flip shielding cover 2 by turning the hand crank by hand; when the driving wheel 82 is connected to the driving motor fixed on the support frame 4, the driving motor drives the driving wheel 82 to rotate by controlling the rotation of the driving motor, and then the flip shielding cover 2 can be opened or closed. In specific implementation, according to actual needs, the rotation of the driving wheel 82 on one side can be controlled to open or close the flip shielding cover 2 on one side, so as to realize the separate control of the opening and closing of the two flip shielding covers 2.

[0047] In this embodiment, a lower stopper 41 and an upper stopper 42 are further provided on the support frame 4, and the lower stopper 41 and the upper stopper 42 are respectively used to limit the range of motion of the lower connecting rod 62 when the flip shield 2 is opened and closed. In this embodiment, the lower stopper 41 and the upper stopper 42 are both made of rubber material, or are a structure in which a rubber sleeve is sleeved on the outside of a steel pipe, so as to have a certain buffering effect when blocking the lower connecting rod 62.

[0048] Embodiment three:

[0049] like Figures 8 to 9 As shown, the split shielding cabin in this embodiment is different from that in the second embodiment in that:

[0050] The driving wheels 82 are double-layer wheels, and the first layer of each driving wheel 82 is connected to the driven wheel 81 on the corresponding side through a first belt 83, and the second layers of the two driving wheels 82 are cross-connected through a second belt 84; one of the driving wheels 82 is provided with a hand crank; or, one of the driving wheels 82 is connected to a driving motor, and the driving motor is fixed on the support frame 4.

[0051] Specifically, the second layers of the two driving wheels 82 are cross-drivenly connected by a second belt 84, that is, the second belt 84 is arranged in an "8" shape between the second layers of the two driving wheels 82. When one of the driving wheels 82 is rotated, the other driving wheel 82 will rotate synchronously in the opposite direction under the transmission action of the second belt 84. With this arrangement, the two flip shielding covers 2 can be opened and closed simultaneously by rotating one of the driving wheels 82.

[0052] In summary, the double-opening shielding cabin provided by the utility model has two flip shielding covers which can be opened and closed on the fixed shielding cover. When the two flip shielding covers are closed, the top of the fixed shielding cover can be sealed. When the two flip shielding covers are opened, the top of the fixed shielding cover is completely open, which is convenient for patients to get on and off the scanning bed and for first aid operations in emergency situations.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0054] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
