[0002] X-ray imaging is widely used in the medical field. It can determine the presence of lesions, guiding treatment. It also has a low radiation dose and is easy to operate. Respiratory gating devices can assist X-ray imaging, reducing airway and esophageal interference caused by breathing and improving image quality. For example, a respiratory gating device with publication number CN109157765B simplifies operation and improves detection accuracy. However, respiratory gating devices require lead wires, which may detach due to accidental contact. The device in the aforementioned application lacks lead wire detachment prevention, potentially affecting its subsequent use.

[0003] Therefore, we propose a respiratory gating device for X-ray imaging to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a breathing gating device for X-ray imaging, in order to solve the problem mentioned in the background art that the device does not have a wire detachment prevention function during use, which would affect the subsequent use of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a breathing gate control device for X-ray imaging, comprising a working plate, an equipment box fixedly connected to the upper surface of the working plate, a patch placed on the upper surface of the working plate, and connecting plates fixedly connected to both sides of the patch, an installation groove opened on the surface of the equipment box, and the equipment box connected to the patch via an external wire, a fixing block fixedly connected to the outer wall of the equipment box, and a limit rod slidably arranged inside the fixing block, a limit plate fixedly connected to the outer wall of the equipment box, a clamping plate slidably arranged on the surface of the limit plate, and the limit plate being inverted "U" shape when viewed from above, a breathable mesh fixedly connected to the outer wall of the equipment box, a guide rod fixedly connected to the outer wall of the equipment box, a sliding plate slidably arranged on the surface of the guide rod, and a striking rod fixedly connected to the surface of the sliding plate.

[0006] Preferably, the limiting rod passes through the interior of the fixing block, and the end of the limiting rod is inclined, and limiting blocks are fixedly connected to both the left and right sides of the limiting rod.

[0007] Preferably, a second spring is fixedly connected to the upper surface of the limiting block, and the other side of the second spring is fixedly connected to the inner wall of the fixing block.

[0008] Preferably, the clamping plates are symmetrically distributed about the center of the mounting groove, and a first spring is fixedly connected to the surface of the clamping plates, and the other side of the first spring is fixedly connected to the inner wall of the limiting plate.

[0009] Preferably, the first spring is initially in a compressed state.

[0010] Preferably, a long plate is fixedly connected to the outer wall of the outer clamping plate, and push blocks are fixedly connected to the surface of the long plate, with the push blocks evenly distributed on the surface of the long plate.

[0011] Preferably, a force-bearing block is fixedly connected to the outer wall of the slide block, and the surface of the force-bearing block and the surface of the push block are both arc-shaped structures.

[0012] Preferably, a partition is fixedly connected to the surface of the guide rod, and a connecting spring is fixedly connected to the surface of the partition, with the other side of the connecting spring fixedly connected to the surface of the slide plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the breathing gating device for X-ray imaging adopts a novel structural design, the specific details of which are as follows:

[0014] This breathing gating device for X-ray imaging works by having the patch adhere to the body via a restraint strap. When connecting the wire connector, the connector is inserted into the mounting groove on the surface of the device housing. Then, the limit rod is pulled to prevent its end from contacting the clamping plate. The clamping plate then moves towards the mounting groove under the action of the first spring and the limit plate. Finally, the clamping plates on both sides hold the wire connector in place, preventing it from accidentally falling off during operation and ensuring stability.

[0015] Furthermore, when it is necessary to remove the wire connector, the corresponding clamping plate can be pushed towards both sides of the mounting groove. When the clamping plate moves to the inclined surface that contacts the limiting rod, the limiting rod drives the limiting block to move in the direction of squeezing the second spring. When the clamping plate continues to move until it no longer pushes the limiting rod, the limiting rod returns to its original position under the action of the limiting block and the second spring. At this time, the limiting rod blocks the clamping plate, making it convenient for the clamping plate to be used again.

[0016] The breathing gating device for X-ray imaging dissipates heat through the ventilation mesh during normal operation of the equipment box, ensuring that the equipment box maintains a normal operating temperature.

[0017] Furthermore, during the movement of the clamping plate, the clamping plate drives the long plate to move synchronously. At this time, the long plate drives the push block to move synchronously, and the push block will intermittently push the force block. When the force block is pushed, the force block drives the slide plate and the striking rod to move closer to the breathable mesh. At this time, the connecting spring will be stretched. When the push block continues to move until it no longer contacts the force block, the force block and the slide plate return to their original position under the action of the connecting spring and the guide rod. The above process is repeated. The slide plate and the striking rod make reciprocating linear motion in the horizontal direction. At this time, the striking rod will hit the breathable mesh repeatedly, causing the dust on the surface of the breathable mesh to be shaken off, thus preventing the breathable mesh from being blocked and ensuring the normal operation of the breathable mesh.

[0018] (3) The breathing gating device for X-ray imaging restricts the movement distance of the skateboard during the movement of the skateboard, thus ensuring stability. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: The clamping plate 5 can quickly hold the wire connector in place, preventing it from falling off. Figures 1-4 As shown, the device includes a work plate 1, an equipment box 2 fixedly connected to the upper surface of the work plate 1, a patch 3 placed on the upper surface of the work plate 1, and connecting plates 4 fixedly connected to both sides of the patch 3. The surface of the equipment box 2 is provided with an installation groove 8, and the equipment box 2 is connected to the patch 3 through an external wire. A fixing block 9 is fixedly connected to the outer wall of the equipment box 2, and a limit rod 10 is slidably provided inside the fixing block 9. A limit plate 6 is fixedly connected to the outer wall of the equipment box 2, and a clamping plate 5 is slidably provided on the surface of the limit plate 6. The top view of the limit plate 6 is an inverted "U" shape. A breathable mesh 18 is fixedly connected to the outer wall of the equipment box 2.

[0029] The clamping plates 5 are symmetrically distributed about the center of the mounting groove 8, and a first spring 7 is fixedly connected to the surface of the clamping plates 5. The other side of the first spring 7 is fixedly connected to the inner wall of the limiting plate 6. The first spring 7 is initially in a compressed state.

[0030] During use, patch 3 is attached to the body via a restraint strap. When connecting the wire connector, the connector is inserted into the mounting groove 8 on the surface of the equipment box 2. Then, the limiting rod 10 is pulled to prevent its end from contacting the clamping plate 5. Under the action of the first spring 7 and the limiting plate 6, the clamping plate 5 moves towards the mounting groove 8. Finally, the clamping plates 5 on both sides hold the wire connector, preventing it from accidentally falling off during operation and ensuring stability. When it is necessary to remove the wire connector, the corresponding clamping plate 5 can be pushed towards both sides of the mounting groove 8. When the clamping plate 5 moves to the inclined surface that contacts the limiting rod 10, the limiting rod 10 drives the limiting block 11 to move towards the direction of squeezing the second spring 12. When the clamping plate 5 continues to move until it no longer pushes the limiting rod 10, the limiting rod 10 returns to its original position under the action of the limiting block 11 and the second spring 12. At this time, the limiting rod 10 blocks the clamping plate 5, making it convenient for the clamping plate 5 to be used again.

[0031] Example 2: Unlike Example 1, the sliding plate 20 and the tapping bar 19 allow dust to be shaken off the surface of the breathable mesh 18, preventing clogging. Figures 5-7As shown, a guide rod 15 is fixedly connected to the outer wall of the equipment box 2, and a slide plate 20 is slidably disposed on the surface of the guide rod 15, and a striking rod 19 is fixedly connected to the surface of the slide plate 20.

[0032] The limiting rod 10 passes through the interior of the fixing block 9, and the end of the limiting rod 10 is inclined. The left and right sides of the limiting rod 10 are fixedly connected to the limiting blocks 11. The upper surface of the limiting block 11 is fixedly connected to the second spring 12, and the other side of the second spring 12 is fixedly connected to the inner wall of the fixing block 9.

[0033] A long plate 13 is fixedly connected to the outer wall of the outer clamping plate 5, and a push block 14 is fixedly connected to the surface of the long plate 13. The push blocks 14 are evenly distributed on the surface of the long plate 13. A force-bearing block 21 is fixedly connected to the outer wall of the slide plate 20. The surface of the force-bearing block 21 and the surface of the push block 14 are both arc-shaped structures. A partition 16 is fixedly connected to the surface of the guide rod 15, and a connecting spring 17 is fixedly connected to the surface of the partition 16. The other side of the connecting spring 17 is fixedly connected to the surface of the slide plate 20.

[0034] When the equipment box 2 is working normally, heat is dissipated through the vent mesh 18 to ensure the normal operating temperature of the equipment box 2. During the movement of the clamping plate 5, the clamping plate 5 drives the long plate 13 to move synchronously. At this time, the long plate 13 drives the push block 14 to move synchronously, and the push block 14 will intermittently push the force block 21. When the force block 21 is pushed, the force block 21 drives the slide plate 20 and the striking rod 19 to move closer to the vent mesh 18. At this time, the connecting spring 17 will be stretched. As the push block 14 continues to move until it no longer contacts the force block 21, the force block 21 will continue to move closer to the vent mesh 18. When the force block 21 is applied, the force block 21 and the slide plate 20 return to their original positions under the action of the connecting spring 17 and the guide rod 15. The above process is repeated, and the slide plate 20 and the striking rod 19 make reciprocating linear motion in the horizontal direction. At this time, the striking rod 19 will strike the ventilation net 18 repeatedly, causing the dust on the surface of the ventilation net 18 to be shaken off, thus preventing the ventilation net 18 from becoming blocked and ensuring the normal operation of the ventilation net 18. During the movement of the slide plate 20, the partition 16 restricts the movement distance of the slide plate 20, ensuring stability.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
