Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0044] Reference Figures 1 to 3 According to the embodiment of the present application, the support platform 100 of the flat panel detector includes a guide rail 10 and a frame 20 . The frame 20 is slidably connected to the guide rail 10 , and the platform detector 30 is placed on the frame 20 .

[0045] Figure 3 The middle arrow indicates the movable direction of the frame 20. When the frame 20 slides relative to the guide rail 10, the flat panel detector 300 can be moved to achieve inspection at different positions.

[0046] When the support platform 100 is used in conjunction with the stretcher 200, the support platform 100 can be disposed below the stretcher 200. The extension direction of the guide rail 10 is the same as the length direction of the stretcher 200. Specifically, the guide rail 10 can be disposed between two legs 210 of the stretcher 200.

[0047] When the frame 20 is moved, the frame 20 moves along the guide rail 10 , so that the flat panel detector 300 can complete the inspection of the patient on the stretcher 200 .

[0048] Compared with the prior art that uses a handheld flat panel detector 300 to examine the injured and sick, which causes the problem of difficult operation, the present application can place the flat panel detector 300 on the support platform 100 and move the flat panel detector 300 through the movable frame 20, thereby facilitating the inspection operation.

[0049] In some embodiments, in conjunction with reference Figure 4 and Figure 5 The guide rail 10 is provided with a guide groove 13, which extends along the length direction of the guide rail 10; the frame 20 includes a support plate 21 and a pulley assembly 22, and the pulley assembly 22 can slide along the guide groove 13, thereby driving the support plate 21 to slide relative to the guide rail 10.

[0050] When in use, the flat panel detector 300 is placed on the support plate 21 , and the flat panel detector 300 is moved by moving the frame 20 .

[0051] Specifically, an extension portion 14 extending outward is provided on the side surface of the guide rail 10 , and a guide groove 13 is formed on the extension portion 14 .

[0052] The pulley assembly 22 is connected to the bottom end of the support plate 21. The pulley assembly 22 may include a pulley 221 and a connecting frame 222.

[0053] When viewed from the side, the connecting frame 222 is in an “L” shape, a lateral end of the connecting frame 222 is connected to the middle of the pulley 221 , and a vertical end of the connecting frame 222 is connected to the support plate 21 .

[0054] The frame 20 and the guide rail 10 are slidably connected via the pulley 221, which can improve the smoothness of sliding. The frame 20 can be moved with only a little force, further improving the convenience of operation and the efficiency of operation.

[0055] Since the guide rail 10 is relatively long, in order to facilitate carrying and storage, the guide rail 10 of the present application is configured as a foldable structure. When not in use, the guide rail 10 can be folded and stored, which facilitates the carrying of the support platform 100.

[0056] In some embodiments, reference Figure 6 The guide rail 10 includes a first section of the guide rail 11 and a second section of the guide rail 12, and the first section of the guide rail 11 and the second section of the guide rail 12 are hinged.

[0057] Exemplarily, the first guide rail section 11 and the second guide rail section 12 are connected by a hinge 40. When the first guide rail section 11 rotates to 180° relative to the second guide rail section 12, the guide rail 10 is in an unfolded state; when the first guide rail section 11 and the second guide rail section 12 rotate toward each other, the guide rail 10 is in a folded state.

[0058] Combination Figure 5 , the hinge 40 can be connected to the top of the guide rail 10. The support plate 21 of the frame 20 is higher than the hinge 40, that is, there is a gap between the bottom end of the support plate 21 and the hinge 40 to prevent the support plate 21 from touching the hinge 40.

[0059] The guide rail 10 can be arranged in a foldable form of two or more sections. The length of the guide rail 10 after folding is not greater than the length of the stretcher 20 after folding, so that the guide rail 10 and the stretcher 20 can be conveniently placed together for carrying.

[0060] Exemplarily, the stretcher 200 is folded into four sections in the length direction. Since the unfolded length of the guide rail 10 is shorter than the unfolded length of the stretcher 200 , the guide rail 10 can be folded into three sections.

[0061] In some embodiments, reference Figure 7The guide rail 10 includes a first guide rail 101 and a second guide rail 102 , and the first guide rail 101 and the second guide rail 102 are arranged along the width direction of the stretcher 200 .

[0062] If there is no connecting structure between the first guide rail 101 and the second guide rail 102, the width distance between the two guide rails is difficult to fix during use. For example, when the width between the two guide rails 10 is not equal to the width distance between the pulley assemblies 22 on the frame 20, the frame 20 is easily deformed during sliding and has problems with sliding.

[0063] Therefore, in the present application, the first guide rail 101 and the second guide rail 102 can be connected in the width direction by a support rod. Specifically, the two ends of the support rod are respectively fixedly connected to the first guide rail 101 and the second guide rail 102. In this case, the guide rail 10 can only be folded in the length direction.

[0064] In another embodiment, the first guide rail 101 and the second guide rail 102 may be connected via a first connecting rod assembly. The first connecting rod assembly includes a plurality of connecting rod assemblies arranged at intervals along the length direction.

[0065] The first connecting rod assembly includes a first connecting rod 51 and a second connecting rod 52 . One end of the first connecting rod 51 is rotatably connected to the first guide rail 101 , one end of the second connecting rod 52 is rotatably connected to the second guide rail 102 , and the other end of the second connecting rod 52 is hinged to the other end of the first connecting rod 51 .

[0066] When the first link 51 and the second link 52 are rotated to a folded state, the first guide rail 101 and the second guide rail 102 can be folded in the width direction; when the first link 51 and the second link 52 are rotated to an unfolded state, the first guide rail 101 and the second guide rail 102 can be expanded in the width direction.

[0067] The first connecting rod 51 and the second connecting rod 52 can be connected to the bottom end of the extension part 14 by screws. The screw passes through the first connecting rod 51 and is screwed to the first guide rail 101, and the screw passes through the second connecting rod 52 and is screwed to the second guide rail 102. A light hole is provided on the first connecting rod 51, and a threaded hole is provided on the second connecting rod 52. The screw passes through the light hole of the first connecting rod 51 and is screwed to the threaded hole of the second connecting rod 52.

[0068] When the first connecting rod 51 and the second connecting rod 52 are in a 180° unfolded state, the screws can be tightened. After the screws are tightened, the unfolded state of the first connecting rod 51 and the first connecting rod 52 is locked, which can avoid the problem of the first connecting rod 51 and the second connecting rod 52 being easy to fold when subjected to external force, thereby ensuring the uniformity of the width dimension of the guide rail 10 in the unfolded state.

[0069] The first connecting rod assembly can ensure the uniformity of the width dimension of the guide rail 10 when it is in the unfolded state, and the first connecting rod assembly can realize the folding of the guide rail 10 in the width direction, so as to facilitate carrying.

[0070] According to the embodiments of the present application, continue to refer to Figure 5 There is a gap between the bottom end of the extension portion 14 and the bottom surface of the guide rail 10. After the first connecting rod assembly is connected to the extension portion 14, the bottom end of the first connecting rod assembly does not protrude from the bottom surface of the guide rail 10. In other words, the height of the bottom end of the first connecting rod assembly is higher than the bottom surface of the guide rail 10, which can ensure that the bottom end is positioned by the bottom surface of the guide rail 10.

[0071] In some embodiments, an auxiliary piece 60 is connected to the end of the guide rail 10 , and a portion of the auxiliary piece 60 may extend outside the guide rail 10 , so that the guide rail 10 may be fixed by pressing the auxiliary piece 60 .

[0072] In a usage scenario, combined with Figure 1 and Figure 7 The end of the guide rail 10 abuts against the support foot 210 , the auxiliary sheet 60 is pressed under the support foot 210 , and the guide rail 10 is fixed by the support foot 210 of the stretcher 200 .

[0073] In another usage scenario, combined with Figure 2 and Figure 7 , the bracket 200 is lifted by the object 400, and at this time, a foreign object can be used to press on the auxiliary sheet 60 to fix the guide rail 10 through the foreign object.

[0074] According to an embodiment of the present application, the auxiliary piece 60 can be rotatably connected to the bottom end of the guide rail 10. When in use, the auxiliary piece 60 can be rotated to expose the guide rail 10. When not in use, the auxiliary piece 60 can be rotated to be covered by the guide rail 10.

[0075] The auxiliary sheet 60 can be rotatably connected to the guide rail 10 via a shaft. An upwardly recessed receiving groove can be provided at the bottom end of the guide rail 10, and the auxiliary sheet 60 is located in the receiving groove when covered.

[0076] In some embodiments, reference Figure 8 and Fig. 9 The support plate 21 includes a fixed plate 211 and a movable plate 212. The flat panel detector 300 is placed on the movable plate 212, and the bottom end of the fixed plate 211 is connected to the pulley assembly 22. A pulley assembly 22 can be respectively arranged at the four corners of the fixed plate 211.

[0077] The pulley assembly 22 may include two pulleys 221 arranged along the length direction, so that the reliability and stability of sliding can be increased.

[0078] Fig. 9 The middle arrow indicates the movable direction of the movable plate 212 . The movable plate 212 can slide relative to the fixed plate 211 . The movable direction of the movable plate 212 is perpendicular to the extending direction of the guide groove 13 . That is, the movable plate 212 can move relative to the fixed plate 211 in the width direction.

[0079] By slidingly connecting the movable plate 212 and the fixed plate 211 in the width direction, the inspection range of the flat panel detector 300 in the width direction can be expanded.

[0080] According to an embodiment of the present application, an installation space is provided in the middle of the fixed plate 211 , and the movable plate 212 is connected in the installation space.

[0081] A slide groove 2111 is provided on the side of the fixed plate 211, and a slider 2121 is provided on the side of the movable plate 212. When in use, the slider 2121 of the movable plate 212 is inserted into the slide groove 2111, and the slider 2121 moves in the slide groove 2111 when the movable plate 212 is pushed or pulled. If necessary, the positions of the slider 2121 and the slide groove 2111 are interchangeable.

[0082] In some embodiments, the fixed plate 211 includes two components spaced apart from each other, the two components being a first fixed plate 2112 and a second fixed plate 2113 , and the space between the first fixed plate 2112 and the second fixed plate 2113 forms an installation space for installing the movable plate 212 .

[0083] The first fixing plate 2112 and the second fixing plate 2113 are connected via a second connecting rod assembly. The second connecting rod assembly includes a third connecting rod 53 and a fourth connecting rod 54 .

[0084] One end of the third link 53 is rotatably connected to the first fixed plate 2112, one end of the fourth link 54 is rotatably connected to the second fixed plate 2113, and the other end of the fourth link 54 is hinged to the other end of the third link 53; when the third link 53 and the fourth link 54 are rotated to a folded state, the first fixed plate 2112 and the second fixed plate 2113 can be gathered in the width direction; when the third link 53 and the fourth link 54 are rotated to an unfolded state, the first fixed plate 2112 and the second fixed plate 2113 can be expanded in the width direction.

[0085] The specific connection structure of the second connecting rod assembly is the same as that of the first connecting rod assembly, and will not be repeated here.

[0086] The fixing plate 211 can be folded and unfolded by the second connecting rod assembly.

[0087] In other embodiments, referring to Fig.10 and Fig.11 The fixed plate 211 is an integral plate, and an installation space is set in the middle of the upper end of the fixed plate 211, and the movable plate 211 is installed in the installation space.

[0088] In some embodiments, the movable panel 212 may also include a first section of movable panel and a second section of movable panel hinged together to achieve folding of the movable panel 212 .

[0089] The upper surface of the movable plate 212 is higher than the fixed plate 211 , so that when the flat panel detector 300 is placed on the movable plate 212 , it is prevented from contacting the fixed plate 211 and affecting the flat panel detector 300 to move with the movable plate 212 .

[0090] In some embodiments, a handle portion 2122 may be provided at the end of the movable plate 212. By holding the handle portion 2116, it is convenient to move the frame 20 or move the movable plate 212, which has the advantage of convenient operation.

[0091] When in use, unfold the guide rail 10 and the frame 20, insert the pulley 221 of the frame 20 into the guide groove 13 of the guide rail 10, then place the guide rail 10 between the legs 210 of the stretcher 200, and place the flat-panel detector 300 on the frame 20; according to the position of the injured person on the stretcher 200, move the frame 20 to adjust the detection position of the flat-panel detector 300 in the length direction, and move the movable plate 212 to adjust the detection position of the flat-panel detector 300 in the width direction. The support platform of the present application enables medical technicians to complete X-ray examinations without moving the injured person and the stretcher, thereby improving the efficiency of examining the injured person. After use, fold the guide rail 10 and the frame 20 for storage.

[0092] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
