The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connections (couplings).
[0038] Currently, the accommodation space under the bed panel in the X-ray imaging system for accommodating the detector module is exposed, and the hands of patients or doctors are likely to reach into the accommodation space, causing harm. The X-ray imaging bed of the present application includes a protective door that can be opened and closed. When the protective door is in the closed state, it can cover the accommodation space, and when the protective door is opened, the detector module can be exposed. Under the protection of the protective door, the safety of the X-ray imaging bed is improved.
[0039] In one embodiment, please refer to Figure 1 and Figure 2 , the X-ray imaging bed assembly includes a radiation detector module 1 and an X-ray imaging bed 2. In one embodiment, the radiation detector module 1 includes a radiation detector (not shown in the figure) and a film cassette 11, and the radiation detector is installed in the film cassette 11. In one embodiment, the radiation detector is a flat panel detector.
[0040] Regarding the X-ray examination table 2, in one embodiment, please refer to Figure 1 and Figure 2 , the X-ray examination table 2 includes a bed frame 21, a bed board 22, and a protective door 23. The bed board 22 is mounted on the bed frame 21. Taking the plane where the bed board 22 is located being parallel to the ground as the reference direction, a receiving space 24 for accommodating the ray detector module 1 is provided below the bed board 22. At least one side of the bed frame 21 has an exposed opening 211, and the exposed opening 211 communicates with the receiving space 24 to expose the ray detector module 1.
[0041] In some other embodiments, the ray detector module 1 may also not have a film cassette 11, and the ray detector can be directly placed in or mounted in the receiving space 24.
[0042] Please refer to Figure 2 , the protective door 23 is movably mounted at the exposed opening 211, and the protective door 23 has an open state and a closed state. When the protective door 23 is in the closed state, it can cover the exposed opening 211, and when in the open state, it can open the exposed opening 211. In this way, the receiving space 24 can be covered by the protective door 23, and maintenance operations or access operations can be performed on the ray detector module 1 in the receiving space 24.
[0043] In one embodiment, please refer to Figure 2 , at least one of the front side and the rear side of the bed frame 21 has an exposed opening 211. In one embodiment, the front-rear direction of the X-ray examination table 2 is the width direction, and the left-right direction is the length direction. The size of the X-ray examination table 2 in the left-right direction is greater than that in the front-rear direction. Of course, the size of the bed board 22 in the left-right direction is also greater than that in the front-rear direction. In one embodiment, when using the X-ray examination table 2 to examine a patient, the doctor usually stands on the front side of the X-ray examination table 2.
[0044] Regarding the position of the exposed opening 211, there are various feasible ways. For example, in one embodiment, please refer to Figure 1 and Figure 2 , both the front side and the rear side of the bed frame 21 have an exposed opening 211. For another example, in one embodiment, only one of the front side and the rear side of the bed frame 21 has an exposed opening 211. For another example, in one embodiment, at least one of the left side and the right side of the bed frame 21 has an exposed opening 211.
[0045] Regarding the size of the exposed opening 211, in one embodiment, please refer to Figure 1 and Figure 2, the size of at least one exposed opening 211 meets the requirement that the radiation detector module 1 can pass through, so as to realize the disassembly and assembly of the radiation detector module, that is, at least one exposed opening 211 is a detector module inlet and outlet for the radiation detector module 1 to pass through. For example, in one embodiment, since doctors usually stand on the front side of the X-ray examination table 2, there is a large activity space on the front side of the bed frame 21, and the exposed opening 211 on the front side of the bed frame 21 is the detector module inlet and outlet, which is more convenient to take and place the radiation detector module 1 through the exposed opening 211. For another example, in one embodiment, both the exposed opening 211 on the front side of the bed frame 21 and the exposed opening 211 on the rear side of the bed frame 21 meet the requirement that the radiation detector module 1 can pass through, and protective doors 23 are installed on both the exposed opening 211 on the front side of the bed frame 21 and the exposed opening 211 on the rear side of the bed frame 21.
[0046] In some other embodiments, the size of the exposed opening 211 can also be smaller than the size of the radiation detector module 1. At this time, the exposed opening 211 is only used to observe the position or movement of the radiation detection module.
[0047] In one embodiment, the radiation detector module 1 is movably installed on the bed frame 21 in the front-back direction. Specifically, in one embodiment, please refer to Figure 1 and Figure 2 , for the convenience of taking and placing the radiation detector, the film cassette 11 is installed in the accommodation space 24, and a drawer-type tray structure is installed in the film cassette 11. When placing the radiation detector, the tray structure is pulled out from the exposed opening 211, so that the radiation detector module 1 is loaded or unloaded from the exposed opening 211. After the radiation detector is placed on the tray structure, it can be pushed into the film cassette 11. The radiation detector can be placed in the film cassette 11 or taken out from the film cassette 11 through the tray structure, and the operation is more convenient. Of course, in some other embodiments, the film cassette 11 can also be taken out as a whole from the exposed opening 211, the radiation detector is placed in the film cassette 11, and then it is placed in the accommodation space 24 as a whole.
[0048] In one embodiment, please refer to Figure 1 and Figure 2 , since the protective door 23 is installed at the exposed opening 211, when the radiation detector module 1 is loaded and unloaded from the exposed opening 211, the protective door 23 needs to be opened in advance. After the protective door 23 is opened, in order to enable the protective door 23 to automatically reset, in one embodiment, the X-ray examination table 2 includes an elastic reset member (not shown in the figure), and the elastic reset member can apply an elastic force to the protective door 23 to make the protective door 23 move towards the closed state when the protective door 23 is in the open state. Specifically, in one embodiment, the elastic reset member is a torsion spring, the protective door 23 is swingably assembled on the bed frame 21, and the torsion spring is installed at the swing axis of the protective door 23. In some other embodiments, the elastic reset member can also be a spring piece or a helical spring.
[0049] In one embodiment, the bed board 22 is movably mounted on the bed frame 21, and the X-ray photography bed 2 includes a bed board driving mechanism (not shown in the figure) for driving the bed board 22 to move relative to the bed frame 21. In this way, the bed board 22 can be moved according to the needs of radiography to adjust the shooting position of the patient.
[0050] Regarding the moving form of the bed board 22 relative to the bed frame 21, in one embodiment, the bed board 22 can move left and right relative to the bed frame 21. When taking radiographs of some special body positions of the patient or patients with special body types (such as obese patients), a single exposure cannot completely cover all effective parts. According to the needs of radiography, the bed board 22 usually needs to be able to float back and forth to increase the radiography range. In one embodiment, the bed board 22 can move back and forth relative to the bed frame 21. The bed board driving mechanism can adopt any feasible driving method. For example, in one embodiment, the bed board driving mechanism includes a cross slide table mechanism and a driving motor. The cross slide table mechanism includes a first slide table and a second slide table, and the first slide table is mounted on the second slide table. The moving directions of the first slide table and the second slide table are perpendicular, and there are two driving motors. One driving motor drives the first slide table to move through a lead screw nut mechanism, and the other driving motor drives the second slide table to move through a lead screw nut mechanism. For another example, in one embodiment, the first slide table can also be driven by a cylinder or an oil cylinder.
[0051] In one embodiment, please refer to Figure 1 and Figure 2 , when in the closed state, the outer side of the protective door 23 facing away from the accommodation space 24 is flush with or smoothly transitions to the side surface of the bed frame 21. In this way, the protective door 23 is more beautiful after being closed, has a better touch feeling, and is not likely to have protruding edges and corners after being closed, so the safety is higher.
[0052] In one embodiment, please refer to Figure 1 and Figure 2 , the protective door 23 is swingably mounted on the bed frame 21. Since the bed board 22 usually needs to move relative to the bed frame 21, mounting the protective door 23 on the bed frame 21 has better stability. Specifically, in one embodiment, please refer to Figure 1 and Figure 2 , the lower side of the protective door 23 is connected to the bed frame 21, and the protective door 23 swings downward from the closed state to the open state. In this way, it is more convenient to open the protective door 23, and the protective door 23 is also likely to remain in the open state under the action of gravity after being opened. In one embodiment, please refer to Figure 1 and Figure 2 , the protective door 23 is in the shape of a long strip extending left and right, and both the left end 231 and the right end 232 of the protective door 23 are movably connected to the bed frame 21. Specifically, in one embodiment, please refer to Figure 2 and Figure 3, the protective door 23 is movably connected to the bed frame 21 through a hinge 25. In some other embodiments, the protective door 23 can also be movably connected to the bed frame 21 through a flexible plate.
[0053] In some other embodiments, in addition to the up-and-down swinging installation method, the swinging axis of the protective door 23 can also extend up and down. At this time, the protective door 23 is a double-leaf door.
[0054] In some other embodiments, in addition to being swing-mounted on the bed frame 21, the protective door 23 can also be in any other feasible manner, such as the protective door 23 is a sliding door, or for another example, the protective door 23 is a folding door.
[0055] In one embodiment, in order to keep the protective door 23 in a closed state, a fixing structure is provided on the bed frame 21, and the fixing structure can fix the protective door 23 to keep the protective door 23 in a closed state. Specifically, in one embodiment, the fixing structure is a magnetic attraction fixing structure, and the magnetic attraction fixing structure and the protective door 23 in the closed state are fixed by magnetic attraction force.
[0056] In one embodiment, please refer to Figure 3 , the magnetic attraction fixing structure is a ball catch 26 installed on the bed frame 21. The protective door 23 includes a door panel 233 and a magnetic attraction plate 234 fixed to the inner side of the door panel 233. The magnetic attraction plate 234 is made of a magnetic material and can attract a magnet. The magnetic attraction plate 234 is a U-shaped plate. In some other embodiments, the magnetic attraction fixing structure can also be a permanent magnet fixed on the bed frame 21.
[0057] In one embodiment, the fixing structure is a push-button switch. For example, the fixing structure is a door latch switch. There is a protective door lock tongue on the protective door 23 that inserts into the door latch switch. After pressing the protective door 23, the protective door lock tongue inserts into the door latch switch to lock the protective door 23. After pressing the protective door 23 again, the lock tongue unlocks from the door latch switch, and the protective door 23 can be opened.
[0058] In some other embodiments, the fixing structure can also be a lock catch fixing structure, and the lock catch fixing structure and the protective door 23 in the closed state are fixed by a lock catch. In some other embodiments, a torsion spring can also be provided between the protective door 23 and the bed frame 21, and the elastic force provided by the torsion spring keeps the protective door 23 in a closed state.
[0059] In one embodiment, in order to be able to observe the position of the ray detector module 1, the protective door 23 is a transparent part or a translucent part. In one embodiment, the protective door 23 is a plastic door or a glass door.
[0060] In one embodiment, please refer to Figure 2 and Figure 3, the edge of the protective door 23 has a folded edge 235 that folds inward, which can make the protective door 23 safer and not easily scratch the operator during operation.
[0061] In an embodiment of an X-ray examination table, the X-ray examination table is the X-ray examination table described in any of the above embodiments, and details are not described herein again.
[0062] In an embodiment of an X-ray examination system, the X-ray examination system includes a ray emitter and an X-ray examination table assembly described in any of the above embodiments, and details are not described herein again.
[0063] In an embodiment, the X-ray examination system includes a control system that can control the synchronous movement of the ray emitter and the ray detector in the horizontal direction.
