Description

Technical Field

[0001] This invention relates to the field of imaging technology, and more particularly to a test tube storage device for contrast agents in CT imaging. Background Technology

[0002] Contrast agents, due to their unique physical properties, can help patients' organs and tissues to be better visualized when injected into the human body, thus helping medical staff to observe them better. When contrast agents are no longer needed, a contrast agent storage device should be prepared.

[0003] Contrast agents undergo degradation reactions under sunlight, resulting in poor contrast imaging. Therefore, contrast agents must be protected from light during storage. Before injection, they need to be shaken to generate microbubbles. Due to the unique physical properties of microbubbles, they can help the contrast agent to develop better images during scanning. Current technology requires placing the contrast agent in the dark and shaking it to generate bubbles when needed. The existing process of storing and retrieving contrast agents is cumbersome. Therefore, a test tube storage device for CT contrast agents is needed that can meet the storage environment requirements and generate microbubbles when the contrast agent is retrieved, integrating the storage and retrieval of the contrast agent. Summary of the Invention

[0004] This invention provides a test tube storage device for contrast agents in CT imaging, which can meet the storage environment requirements of the contrast agent and generate microbubbles when the contrast agent is removed by shaking it, thus integrating the storage and retrieval of the contrast agent and overcoming the shortcomings of the complicated process of storing and retrieving contrast agents in the prior art.

[0005] The technical solution is as follows: A test tube storage device for CT contrast agents includes a storage box with an open front. Multiple equally spaced inlets are located on the top of the storage box. A curtain is positioned in the open front of the storage box. Multiple fixing rings are placed on the bottom wall of the storage box, with hollow bottoms. A rotating platform is rotatably connected to each fixing ring. A storage container is fixedly connected to the top of the rotating platform. Contrast agent test tubes are placed inside the storage container. The device also includes telescopic columns, with multiple telescopic columns fixedly connected to the inner wall of the storage box. Fixing rings are connected to the telescopic ends of the telescopic columns. A pressure spring is wound around the telescopic column, with one end fixedly connected to the fixing ring and the other end fixedly connected to the storage box. A limiting component is slidably connected to the side of the storage box away from the curtain, engaging with the fixing rings to restrict their movement. A clamping component is located on the inner wall of the storage container, engaging with the test tubes to clamp them.

[0006] Furthermore, the limiting component includes connectors, multiple connectors are slidably connected to the side of the storage box away from the curtain, the connectors are evenly spaced, one end of the connector is close to the bottom of the storage box, the other end of the connector extends vertically at a 90-degree angle, the connector corresponds to each nearby telescopic post, the actuating rod is connected to the vertically extending end of the connector, the actuating rod is slidably connected to the storage box, the first telescopic rod is connected to the bottom of the actuating rod, a storage spring is wound around the first telescopic rod, one end of the storage spring is fixedly connected to the bottom of the actuating rod, the other end is fixedly connected to the storage box, a triangular plate is connected to the end of the connector away from the actuating rod, the triangular plate is slidably connected to the bottom of the storage box, and the fixing ring engages with the triangular plate.

[0007] Furthermore, the clamping assembly includes a squeezing plate, which is rotatably connected to both sides of the inner wall of the storage container. The contrast agent test tube is squeezed and engaged with the squeezing plate. One end of the torsion spring is fixedly connected to the squeezing plate, and the other end of the torsion spring is fixedly connected to the storage container.

[0008] Furthermore, it also includes a vibration mechanism for adding air bubbles to the contrast agent. The vibration mechanism includes a sealing cap, which is located on the top of the contrast agent test tube and engages with the contrast agent test tube. A first gear is fixedly connected to a rotating platform, and multiple first racks are fixedly connected to the inner bottom of the storage box. The first racks mesh with adjacent first gears. A bouncing component is located at the inner bottom of the storage box near the fixing ring. The bouncing component is pressed and engaged with the fixing ring and is used to agitate the contrast agent. An agitating component is rotatably connected to the sealing cap and is used to agitate the contrast agent.

[0009] Furthermore, the bouncing component includes a bouncing block, with multiple sets of bouncing blocks slidably connected to the lower inner part of the storage box. Each set has multiple bouncing blocks, and the bouncing blocks are pressed together with the fixing ring. A return spring is wound around the bouncing block, with one end of the return spring fixedly connected to the bouncing block and the other end of the return spring fixedly connected to the storage box.

[0010] Furthermore, the agitation assembly includes a second gear rotatably connected to the sealing cover, multiple second racks fixedly connected to the inner top of the storage box, the second racks meshing with adjacent second gears, and an agitator fixedly connected to the bottom of the second gear, the agitator being placed inside the contrast agent.

[0011] Furthermore, it also includes a clamping mechanism for holding the curtain. The clamping mechanism includes a first fixed frame symmetrically arranged, which is fixedly connected to both sides of the storage box. A second telescopic rod is fixedly connected to the inside of the first fixed frame. A screw is fixedly connected to the telescopic end of the second telescopic rod. The curtain is pressed against the screw. A connecting rod is rotatably connected to the first fixed frame. The second telescopic rod is slidably connected to the inside of the connecting rod. The screw is threadedly connected to the inside of the connecting rod. A rotating rod is rotatably connected to the bottom of the storage box. A belt is wound around the rotating rod and the connecting rod via a transmission wheel. Connecting blocks symmetrically arranged laterally along the connecting rod are fixedly connected to the rotating rod near the belt. Fixing blocks are fixedly connected between the symmetrically arranged connecting blocks. The fixing blocks are pressed against the curtain.

[0012] Furthermore, it also includes a disassembly mechanism for detaching the sealing cap from the contrast agent test tube. The disassembly mechanism includes a fixing component, multiple fixing components are fixedly connected to the inside of the storage box, the fixing component has an inclined block away from the guide plate, the second fixing frame is pressed and engaged with the inclined block of the fixing component, multiple sets of guide plates are fixedly connected to the inside of the storage box, each set includes vertically symmetrically arranged guide plates, the third rack is slidably connected between the symmetrically arranged guide plates, the third rack meshes with the first gear, the telescopic component is fixedly connected to the end of the third rack near the storage container, the second fixing frame is fixedly connected to the end of the telescopic component away from the first gear, and the second fixing frame is engaged with the sealing cap.

[0013] Furthermore, the insertion plug is fixedly connected to the inner wall of the inlet. The insertion plug is made of rubber and has a cross-shaped opening on its top. The insertion plug is squeezed together with the contrast agent test tube.

[0014] Furthermore, the bottom of the storage box is fixedly connected to multiple wheels, which are used to move the contrast agent.

[0015] The beneficial effects are:

[0016] 1. This invention places contrast agent test tubes into a storage container. By pressing down the curtain, the fixing ring moves forward, thereby moving the contrast agent test tubes forward. The contrast agent test tubes that move forward can be directly removed from the curtain, preventing the contrast agent stored in the storage box from being degraded under sunlight, making the storage and retrieval of the contrast agent more convenient.

[0017] 2. In this invention, during the forward movement of the fixed ring, the first rack meshes with the first gear, which rotates clockwise. The rotation of the first gear causes the contrast agent tube to rotate as well. The second gear meshes with the second rack, which drives the stirring element to rotate counterclockwise. In this way, the inside and outside of the contrast agent move against each other, agitating the contrast agent. The spring block causes the contrast agent tube to shake up and down. Through the above operation, more microbubbles can be generated in the contrast agent, which helps the contrast agent to be visualized in the human body.

[0018] 3. In this invention, the rotating block rotates, which in turn drives the rotating rod to rotate. The rotating rod then drives the belt to rotate, causing the screw to extend from the connecting rod. Once the screw extends, it connects the curtains together, preventing external factors such as wind from tearing the curtains open and allowing sunlight to shine into the contrast agent, thus affecting the contrast agent.

[0019] 4. In this invention, the first gear drives the third rack to move to the right, thereby causing the telescopic component and the second fixing frame to move to the right. The second fixing frame will engage with the sealing cap. As the contrast agent test tube moves forward, the inclined block of the fixing component will press the second fixing frame upward, causing the sealing cap to be pulled out of the contrast agent test tube. This can save the effort of pulling out the sealing cap and reduce the time to remove the contrast agent from the contrast agent test tube, allowing the contrast agent to be exposed to less sunlight.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0034] Example 1: A test tube storage device for CT contrast agents, such as... Figures 1-5As shown, the system includes a storage box 1, a curtain 11, a triangular plate 12, a rotating table 13, a pressure spring 14, a connector 15, a storage spring 16, a first telescopic rod 17, a toggle rod 18, a torsion spring 19, a squeezing plate 110, a storage bucket 111, a fixing ring 112, and a contrast agent test tube 113. The storage box 1 has an open front structure, and three equally spaced inlets are provided on the top of the storage box 1. The curtain 11 is positioned in the open front of the storage box 1. The three connectors 15 are slidably connected to the rear of the storage box 1 and are evenly spaced. One end of the connector 15 is tightly attached to the lower inner part of the storage box 1, and the other end... The end extends vertically upward at a 90-degree angle. The actuating lever 18 is connected to the vertically upward-extending end of the connecting piece 15. The actuating lever 18 and the storage box 1 are slidably connected. The first telescopic lever 17 is connected to the bottom of the actuating lever 18. The storage spring 16 is wrapped around the first telescopic lever 17. One end of the storage spring 16 is fixedly connected to the bottom of the actuating lever 18, and the other end is fixedly connected to the rear of the storage box 1. The rear of the triangular plate 12 is connected to the end of the connecting piece 15 that is close to the lower part of the storage box 1. The triangular plate 12 is slidably connected to the bottom of the storage box 1. Three telescopic posts 114 are fixedly connected to the rear wall of the storage box 1, and each telescopic post... 114 corresponds to the positions of the nearby connectors 15. Three fixing rings 112 are placed on the bottom wall of the storage box 1. The bottom of the fixing ring 112 is hollow. The front of the fixing ring 112 is locked in the triangular plate 12. The rear of the fixing ring 112 is connected to the front end of the telescopic column 114. The pressure spring 14 is wrapped around the telescopic column 114 behind the fixing ring 112. The front end of the pressure spring 14 is fixedly connected to the rear of the fixing ring 112, and the rear end of the pressure spring is fixedly connected to the rear wall of the storage box 1. A rotating platform 13 is rotatably connected to the fixing ring 112. The storage buckets 111 are fixedly connected to the rotating platform 13. Above, and directly below the three equally spaced feed inlets on the top of the storage box 1, the storage bucket 111 is placed inside the storage bucket 111. The insertion plugs are fixedly connected to the inner wall of the feed inlet. The insertion plugs are made of rubber and have a cross-shaped opening on the top. The insertion plugs are squeezed together with the contrast agent tubes 113. The extrusion plate 110 is rotatably connected to both sides of the inner wall of the storage bucket 111. The contrast agent tubes 113 are squeezed together with the extrusion plate 110. One end of the torsion spring 19 is fixedly connected to the extrusion plate 110, and the other end of the torsion spring 19 is fixedly connected to the storage bucket 111.

[0035] When it is necessary to place the contrast agent test tube 113 into the container, firstly, simply insert the contrast agent test tube 113 from top to bottom into the corresponding storage container 111 in the storage box 1. During the insertion process, the contrast agent test tube 113 will squeeze the insertion plug, and the cross-shaped opening of the insertion plug will expand under the squeezing action, allowing the contrast agent test tube 113 to be inserted. After the contrast agent test tube 113 moves downward and disengages from the insertion plug, because the insertion plug is made of rubber and has elasticity, the cross-shaped opening of the insertion plug will close again, resealing the outlet. When the contrast agent test tube 113 is inserted into the storage container 111, the contrast agent test tube 113 will squeeze the squeezing plate 110, and the squeezing plate 110 will rotate towards the inner wall of the storage container 111. At this time, the torsion spring 19 is in a charged state, causing the compression plate 110 to lock the contrast agent test tube 113. The curtain 11 is made of non-transparent material and has a light-blocking function, which can block the open structure in front of the storage box 1 and protect the CT contrast agent in the contrast agent test tube 113 in the storage container 111 from light. This meets the requirement of light-protected storage of the contrast agent according to the stability test results of the CT contrast agent. This is mainly because the degree of degradation caused by light depends on the brightness of the light and the near-ultraviolet spectrum in sunlight and daylight is very active in photochemical reactions. In addition to its high brightness, sunlight also contains a large amount of ultraviolet rays, which will cause a strong photochemical reaction. The contrast agent will be destroyed not only by short-wavelength light but also by X-rays. Therefore, the curtain 11 can effectively block light from the CT contrast agent. When the contrast agent tube 113 needs to be removed, the user simply needs to push the lever 18 downwards. At this time, the first telescopic lever 17 and the storage spring 16 are both compressed. The downward movement of the lever 18 will cause the connecting piece 15 below to move downwards. Then, the connecting piece 15 at the other end will push the triangular plate 12, causing the triangular plate 12 to retract into the lower part of the storage box 1. At this time, the triangular plate 12 will be separated from the fixing ring 112. Since the fixing ring 112 is no longer blocked by the triangular plate 12, the pressure spring 14 and the telescopic column 114, which were originally compressed, will extend forward, pushing the fixing ring 112, the rotating table 13, and the storage box 11. Moving forward together, the storage container 111 will cause the contrast agent tubes 113 inside it to move forward until they are removed from the curtain 11. This allows for easy removal of the contrast agent tubes 113 from the storage container 111. After the contrast agent tubes 113 are removed, the torsion spring 19 will change from a charged state to a released state. The torsion spring 19 will then cause the compression plate 110 to rotate away from the inner wall of the storage container 111 and return to its original position. Once the contrast agent tubes 113 are removed from the storage container 111, the actuating lever 18 can be released. The first telescopic lever 17 and the storage spring 16, which were in a compressed state, will also return to normal. Under the action of the first telescopic lever 17 and the storage spring 16, the actuating lever 18 will move upward.Then, the fixing ring 112 can be manually pushed backward to reset, simultaneously resetting the rotating platform 13 and the storage bin 111. The pressure spring 14 and the telescopic column 114 will be compressed. During the resetting process, when the fixing ring 112 contacts the triangular inclined surface of the triangular plate 12, it will push the triangular plate 12 downward. At this time, the first telescopic rod 17 and the storage spring 16 will be compressed again. When the fixing ring 112 moves backward to the rear of the triangular plate 12 and separates from the triangular inclined surface, the first telescopic rod 17 and the storage spring 16, which were in a compressed state, will return to normal. Under the action of the first telescopic rod 17 and the storage spring 16, the connecting piece 15 will move upward. At this time, the fixing ring 112... 12 will be restricted again by the triangular plate 12. In summary, by simply moving the lever 18 downwards, the triangular plate 12 will release the fixing ring 112, causing it to move forward and remove the contrast agent tube 113 from the curtain 11. This allows for easy removal of the contrast agent tube 113 from the storage container 111. This contrast agent tube 113 storage device for CT contrast agents adopts a split design. The advantage of this design is that the three storage containers 111 can each hold three contrast agent tubes 113 individually, facilitating independent access to the tubes and preventing interference with the light-protected storage of the CT contrast agent when retrieving a single tube.

[0036] Example 2: Based on Example 1, such as Figure 6 and Figure 7 As shown, it also includes a vibration mechanism for adding air bubbles to the contrast agent. The vibration mechanism includes a return spring 2, a spring block 21, a first rack 22, a first gear 23, a second gear 24, a second rack 25, a stirring element 26, and a sealing cap 27. The sealing cap 27 is respectively positioned above the contrast agent test tube 113 and engages with the contrast agent test tube 113. The second gears 24 are all rotatably connected to the sealing caps 27. The three second racks 25 are fixedly connected to the inner top of the storage box 1, and the second racks 25 respectively mesh with the adjacent second gears 24. The stirring element 26 is fixedly connected below the second gears 24 and stirs... Component 26 is located below the sealing cover 27. The first gear 23 is fixedly connected to the rotating table 13. The three first racks 22 are fixedly connected to the inner bottom of the storage box 1. The first racks 22 are located on the left side of the storage barrel 111. The first racks 22 mesh with the adjacent first gears 23. Three sets of spring blocks 21 are slidably connected to the lower front part of the inner side of the storage box 1. Each set has 3 spring blocks 21. The spring blocks 21 are pressed and engaged with the fixing ring 112. The return spring 2 is wound around the spring block 21. One end of the return spring 2 is fixedly connected to the spring block 21, and the other end of the return spring 2 is fixedly connected to the storage box 1.

[0037] Microbubbles in the contrast agent travel with the bloodstream to the designated body part. Due to the significant difference in acoustic systems between microbubbles and body tissues, microbubbles tend to produce stronger reflections and scattering, facilitating the visualization of lesions. Therefore, before injecting the contrast agent into the patient, it is necessary to generate more microbubbles. Before placing the contrast agent test tube 113 into the storage container 111, the contrast agent is first loaded into the contrast agent test tube 113, and then the sealing cap 27 is placed on top of the contrast agent test tube 113. The second gear 24 is also positioned above the contrast agent test tube 113 along with the sealing cap 27. At this time, the stirring element 26 is immersed in the contrast agent. As mentioned above, when it is necessary to remove the contrast agent, the fixing ring 112 will move forward because the first rack 22 and the fixing ring 112 mesh. When the fixed ring 112 moves forward, it rotates clockwise. This rotation causes the first gear 23 to rotate clockwise as well. The rotation of the first gear 23 causes the rotating table 13 to rotate, which in turn causes the storage container 111 and the contrast agent tube 113 to rotate clockwise. The forward movement of the fixed ring 112 also causes the contrast agent tube 113 and the sealing cap 27 to move forward. The movement of the sealing cap 27 causes the second gear 24 to move forward. Because the second gear 24 meshes with the second rack 25, the movement of the second gear 24 causes it to rotate counterclockwise. This counterclockwise rotation of the second gear 24 causes the stirring element 26 to rotate counterclockwise as well. The clockwise rotation of the contrast agent tube 113 causes the stirring element inside the contrast agent tube 113 to rotate. When component 26 rotates counterclockwise, the inside and outside of the contrast agent tube 113 move relative to each other, agitating the contrast agent inside the tube and generating microbubbles. As the fixing ring 112 extends forward, because its bottom is hollow, the front of the bottom of the fixing ring 112 presses against the spring block 21. The spring block 21 moves downward under the pressure of the fixing ring 112, compressing the return spring 2. The fixing ring 112 continues to move. When the spring block 21 is in the hollow position at the bottom of the fixing ring 112, the fixing ring 112 no longer presses against the spring block 21, and the return spring 2 extends. The extension of the return spring 2 causes the spring block 21 to move upward, which in turn presses against and pushes the fixing ring 112 upward. As the fixed ring 112 continues to move forward, the rear of its bottom will re-press the spring block 21, compressing the return spring 2 again. When the rear of the fixed ring 112 disengages from the spring block 21, the return spring 2 extends, causing the spring block 21 to move upward and reset. As the fixed ring 112 passes through the three spring blocks 21, it is lifted upwards. The subsequent descent of the fixed ring 112 causes the rotating table 13 to vibrate up and down. This vibration causes the contrast agent inside the rotating table 13 to vibrate up and down, generating microbubbles. Thus, during the forward movement of the fixed ring 112, the contrast agent tube 113 rotates, and the stirring element 26 within the contrast agent tube 113 also rotates. Both rotations simultaneously agitate the contrast agent, generating microbubbles.In addition, the spring block 21 also causes the injection to vibrate up and down, generating microbubbles.

[0038] like Figure 8 and Figure 9 As shown, it also includes a clamping mechanism for holding the curtain 11. The clamping mechanism includes a screw 3, a connecting rod 31, a belt 32, a fixing block 33, a connecting block 34, a first fixing frame 35, a second telescopic rod 36, and a rotating rod 37. The first fixing frame 35 is fixedly connected to the left and right sides of the storage box 1, respectively. The second telescopic rod 36 is fixedly connected to the inside of the first fixing frame 35. The screw 3 is fixedly connected to the telescopic end of the second telescopic rod 36, and the curtain 11 is pressed against the screw 3. The connecting rod 37 is fixedly connected to the second telescopic rod 36. The first fixed frame 35 is rotatably connected to the second telescopic rod 36, which is slidably connected to the inside of the connecting rod 31. The screw 3 is threadedly connected to the inside of the connecting rod 31. The rotating rod 37 is rotatably connected to the bottom front side of the storage box 1. The belt 32 is wound between the rotating rod 37 and the connecting rod 31 through the transmission wheel. The connecting block 34 is fixedly connected to the rotating rod 37 near the belt 32. The fixing block 33 is fixedly connected between the two connecting blocks 34. The fixing block 33 is pressed and engaged with the curtain 11.

[0039] When the contrast agent is in storage, the external environment is changeable, and the curtain 11 may be torn open due to wind or accidental contact, easily exposing the contrast agent to sunlight and causing degradation. Therefore, a clamping mechanism is needed to hold the curtain 11. When the contrast agent is not needed, the operator manually rotates the fixing block 33 upwards. The upward rotation of the fixing block 33 gradually contacts and compresses the curtain 11. The rotation of the fixing block 33 drives the connecting block 34 to rotate, which in turn drives the rotating rod 37 to rotate. The rotation of the rotating rod 37 causes the belt 32 to rotate, which in turn drives the connecting rod 31 to rotate. The rotation of the connecting rod 31 causes the screw 3 to move inwards, which in turn causes the telescopic end of the second telescopic rod 36 to move inwards. When both screws 3 move inwards until they connect, the screws 3 are located at the lower rear of the curtain 11, while the fixing block 33 is located at the lower front of the curtain 11. At this time, the screws 3 and the upward-rotating fixing block 33 work together to squeeze the curtain 11. When pressed, the curtain 11 is held stable. When the contrast agent needs to be removed, the fixing block 33 is rotated downwards. The rotation of the fixing block 33 causes the connecting block 34 to rotate downwards. The rotation of the connecting block 34 stops pressing on the curtain 11. The rotation of the connecting block 34 will cause the belt 32 to rotate in the opposite direction. The belt 32 will cause the connecting rod 31 to rotate. The connecting rod 31 will cause the screw 3 to move closer to the first fixing frame 35. The movement of the connecting rod 31 will press on the second telescopic rod 36, causing the second telescopic rod to... The telescopic end of rod 36 also moves towards the first fixed frame 35 to reset. After the screw 3 moves outward to reset, the screw 3 no longer contacts and presses against the rear of the curtain 11. The curtain 11 can be opened. The contrast agent tube 113 moves forward and opens the curtain 11, allowing the contrast agent tube 113 to extend out of the storage box 1. In this way, when the contrast agent is not needed, the screw 3 will connect the curtains 11 to prevent the external environment from opening the curtains 11 and causing the contrast agent to come into contact with sunlight.

[0040] like Figures 10-12 As shown, it also includes a disassembly mechanism for disengaging the sealing cap 27 from the contrast agent tube 113. The disassembly mechanism includes a guide plate 4, a telescopic component 41, a second fixing frame 42, a third rack 43, and a fixing component 44. The three fixing components 44 are fixedly connected to the inner rear side of the storage box 1. Each fixing component 44 has a beveled block at its front end. Three sets of guide plates 4 are fixedly connected to the inner rear side of the storage box 1. Each set includes upper and lower guide plates 4. The third rack 43 is slidably connected between the upper and lower guide plates 4. The third rack 43 meshes with the first gear 23. The telescopic components 41 are fixedly connected to the front of the third rack 43. The second fixing frame 42 is fixedly connected to the upper end of the telescopic component 41. The second fixing frame 42 is engaged with the sealing cap 27. The second fixing frame 42 is pressed against the beveled block of the fixing component 44.

[0041] When contrast agent is needed, the retaining ring 112 will move the contrast agent forward. The operator needs to remove the sealing cap 27 to draw the contrast agent into the syringe. Removing the sealing cap 27 takes time, during which the contrast agent is exposed to sunlight and is easily decomposed. Therefore, a disassembly mechanism is provided to remove the sealing cap 27 from the contrast agent tube 113. As mentioned earlier, when the contrast agent moves forward, the first gear 23 rotates clockwise. This rotation drives the third rack 43 to move to the right, which in turn drives the telescopic component 41 and the second fixing frame 42 to move to the right. The second fixing frame 42 engages with the sealing cap 27, and the contrast agent tube 113 continues to move forward. This forward movement of the contrast agent tube 113 also drives the second fixing frame 42 forward. At this time, the telescopic end of the telescopic component 41 extends forward. During the forward movement of the second fixing frame 42, it engages with the inclined block of the fixing component 44. Upon contact and pressure, the second fixing bracket 42 will be lifted under the pressure of the inclined block. Because the second fixing bracket 42 is engaged with the sealing cap 27, the lifting of the second fixing bracket 42 will cause the sealing cap 27 to be pulled out of the contrast agent tube 113. Then the contrast agent tube 113 will continue to move forward and be removed from the curtain 11. The staff can then take the contrast agent tube 113 out of the storage container 111 and remove the already pulled-out sealing cap 27. The contrast agent can then be drawn from the contrast agent tube 113 using a syringe. When a new contrast agent needs to be stored in the storage box 1, the staff can pull the telescopic component 41 to the left, so that the telescopic component 41 drives the third rack 43 to move to the left and reset. Then the fixing ring 112 can be pushed back to reset, and the third rack 43 will re-mesh with the first gear 23. In this way, the sealing cap 27 can be pulled out from the contrast agent test tube 113 while the contrast agent test tube 113 is moving forward, saving manpower and reducing the time the contrast agent is exposed to sunlight.
