[0002] Due to its unique physical properties, contrast agents can be injected into the human body to help the patient's organs and tissues to be better visualized, thereby helping medical staff to better observe them. When the contrast agent is not needed, a contrast agent tube storage device must be prepared.

[0003] Contrast agents will undergo degradation reactions under the irradiation of sunlight, resulting in poor contrast agent development effect. When storing contrast agents, they need to be protected from light. Before injecting the contrast agents into the patient's body, they need to be shaken to produce microbubbles.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0034] Embodiment 1: A test tube storage device for CT contrast agent, such as Figure 1-Figure 5As shown, it includes a storage box 1, a curtain 11, a triangular plate 12, a rotating table 13, a pressure spring 14, a connecting piece 15, a force storage spring 16, a first telescopic rod 17, a toggle rod 18, a torsion spring 19, an extrusion plate 110, a storage barrel 111, a fixing ring 112 and a contrast agent test tube 113. The front of the storage box 1 is an open structure, and three feeding ports with equal spacing are opened on the top of the storage box 1. The curtain 11 is set in an open position in front of the storage box 1. Three connecting pieces 15 are slidably connected to the rear of the storage box 1 and are evenly spaced. One end of the connecting piece 15 is close to the bottom of the storage box 1, and the other end is close to the bottom of the storage box 1. The end of the connecting member 15 extends vertically upward at 90 degrees, the toggle rod 18 is connected to one end of the connecting member 15 extending vertically upward, the toggle rod 18 and the storage box 1 are slidably connected, the first telescopic rod 17 is connected to the bottom of the toggle rod 18, the storage spring 16 is wound around the first telescopic rod 17, one end of the storage spring 16 is fixedly connected to the bottom of the toggle rod 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 member 15 close to the bottom of the storage box 1, the triangular plate 12 is slidably connected to the bottom of the storage box 1, and three telescopic columns 114 are fixedly connected to the rear wall of the storage box 1, and each telescopic column 114 respectively correspond to the positions of the nearby connecting members 15, three fixing rings 112 are placed on the inner bottom wall of the storage box 1, the bottom of the fixing ring 112 is in a hollow state, the front of the fixing ring 112 is stuck 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 wound around the telescopic column 114 behind the fixing ring 112, and 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 inner rear wall of the storage box 1, the fixing ring 112 is rotatably connected to the rotating table 13, and the storage buckets 111 are respectively fixedly connected to the rotating table 13 Above, the storage barrels 111 are respectively located directly below the three feed ports evenly spaced at the top of the storage box 1, the contrast agent tubes 113 are placed in the storage barrels 111, and the insertion plugs are fixedly connected to the inner wall of the feed port. The insertion plugs are made of rubber, and a cross is marked on the top of the insertion plugs. The insertion plugs are squeezed and matched with the contrast agent tubes 113, and the squeezing plate 110 is rotatably connected to both sides of the inner wall of the storage barrel 111. The contrast agent tubes 113 are squeezed and matched with the squeezing plate 110, one end of the torsion spring 19 is fixedly connected to the squeezing plate 110, and the other end of the torsion spring 19 is fixedly connected to the storage barrel 111.

[0035] When it is necessary to place the contrast agent test tube 113 in the container, first, it is only necessary to insert the contrast agent test tube 113 from the top to the bottom from the feed port into the corresponding storage barrel 111 in the storage box 1. During the process of inserting the contrast agent test tube 113 into the feed port, the contrast agent test tube 113 will squeeze the insertion plug, and the cross-mouth of the insertion plug will expand under the squeezing action, so that the contrast agent test tube 113 can 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-mouth of the insertion plug will close again and reseal the discharge port. When the contrast agent test tube 113 is inserted into the storage barrel 111, the contrast agent test tube 113 will squeeze the squeezing plate 110, and the squeezing plate 110 will rotate toward the inner wall of the storage barrel 111. At this time, the torsion spring 19 is in a state of storing force, so that the extrusion plate 110 clamps the contrast agent test tube 113. The blind 11 is made of a non-transparent material and has a light-shielding effect. It can block the structure open in front of the storage box 1 and can protect the CT contrast agent in the contrast agent test tube 113 in the storage barrel 111 from light, which can meet the requirements of the CT contrast agent stability test results that the contrast agent should be stored away from light. This is mainly because the degree of degradation caused by light mainly 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 not only be destroyed by short-wave light, but also by X-rays. Therefore, the blind 11 can meet the purpose of shading the CT contrast agent, and when the contrast agent tube 113 needs to be taken out, people only need to push the toggle rod 18 downward by hand. At this time, the first telescopic rod 17 and the force storage spring 16 are both in a compressed state. The downward movement of the toggle rod 18 will drive the lower connecting piece 15 to move downward, and then the connecting piece 15 connected to the other end will push the triangular plate 12, so that the triangular plate 12 is retracted into the inner bottom of the storage box 1. At this time, the triangular plate 12 and the fixed ring 112 will be in a separated state. Since the fixed ring 112 loses the obstruction of the triangular plate 12, the pressure spring 14 and the telescopic column 114, which were originally in a compressed state, will stretch forward, and will push the fixed ring 112, the rotating table 13 and the storage bucket 11 1 moves forward together, and the forward movement of the storage barrel 111 will drive the contrast agent test tube 113 in the corresponding storage barrel 111 to move forward to move out of the curtain 11, so that people can easily take out the contrast agent test tube 113 in the storage barrel 111. After the contrast agent test tube 113 is taken out of the storage barrel 111, the torsion spring 19 will be converted from the force storage state to the pressure release state, and the torsion spring 19 will drive the extrusion plate 110 to rotate and reset in the direction away from the inner wall of the storage barrel 111. When people take out the contrast agent test tube 113 in the storage barrel 111, they can release the toggle rod 18, and the first telescopic rod 17 and the force storage spring 16 in the compressed state will also return to normal. Under the action of the first telescopic rod 17 and the force storage spring 16, the toggle rod 18 will move upward.Then people can manually push the fixing ring 112 backward to reset, and at the same time drive the rotating table 13 and the storage bucket 111 to reset together, the pressure spring 14 and the telescopic column 114 will be compressed, and when the fixing ring 112 moves and resets, it will contact the triangular inclined surface of the triangular plate 12 and push the triangular plate 12 to move downward, at this time the first telescopic rod 17 and the force storage spring 16 are compressed again, and 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 force storage spring 16 in the compressed state will return to normal, and under the action of the first telescopic rod 17 and the force storage spring 16, the connecting piece 15 will move upward, and the fixing ring 112 will be in a state of being compressed. 12 will be restricted by the triangle plate 12 again. In summary, people only need to push the toggle lever 18 downward to drive the triangle plate 12 to release the fixing ring 112. The fixing ring 112 will move forward to move the contrast agent tube 113 out of the curtain 11. At this time, people can easily take out the contrast agent tube 113 in the storage barrel 111. This contrast agent tube 113 storage device for CT contrast agent adopts a split design. The advantage of this design is that the three storage barrels 111 can store three contrast agent tubes 113 separately, which is convenient for people to take the contrast agent tube 113 independently, and can avoid affecting the light-proof storage of CT contrast agent when taking a single contrast agent tube 113.

[0036] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, it also includes a vibrating mechanism for adding bubbles to the contrast agent, the vibrating mechanism includes a reset spring 2, a spring block 21, a first rack 22, a first gear 23, a second gear 24, a second rack 25, a stirring member 26 and a sealing cover 27, the sealing covers 27 are respectively arranged above the contrast agent test tube 113, the sealing covers 27 are engaged with the contrast agent test tube 113, the second gears 24 are rotatably connected to the sealing covers 27, the three second racks 25 are fixedly connected to the inner top of the storage box 1, the second racks 25 are respectively engaged with the adjacent second gears 24, the stirring members 26 are respectively fixedly connected below the second gears 24, and the stirring Component 26 is located below the sealing cover 27, the first gears 23 are fixedly connected to the rotating table 13, three first racks 22 are fixedly connected to the inner bottom of the storage box 1, the first rack 22 is located on the left side of the storage barrel 111, the first rack 22 is meshed with the adjacent first gear 23, and three groups of spring blocks 21 are slidably connected to the front position of the inner lower part of the storage box 1, each group is provided with 3 spring blocks 21, the spring blocks 21 are squeezed and matched with the fixing ring 112, the reset spring 2 is wound on the spring block 21, one end of the reset spring 2 is fixedly connected to the spring block 21, and the other end of the reset spring 2 is fixedly connected to the storage box 1.

[0037] The microbubbles in the contrast agent will reach the designated body part with the blood flow. Due to the large difference in the acoustic system between microbubbles and body tissues, microbubbles are prone to produce stronger reflection and scattering, which is convenient for the imaging of the lesion. Therefore, before the contrast agent is injected into the patient's body, the contrast agent should be allowed to produce more microbubbles. Before the contrast agent tube 113 is placed in the storage barrel 111, the contrast agent is first loaded into the contrast agent tube 113, and then the sealing cover 27 is covered on the top of the contrast agent tube 113. The second gear 24 will also be located above the contrast agent tube 113 with the sealing cover 27. At this time, the stirring member 26 is immersed in the contrast agent. As mentioned above, when the contrast agent needs to be taken out, the fixing ring 112 will move forward because the first rack 22 and the fixing ring 112 are meshed. The fixing ring 112 moves forward to rotate the fixing ring 112 in the clockwise direction. The rotation of the fixing ring 112 drives the first gear 23 to rotate clockwise. The rotation of the first gear 23 drives the rotating table 13 to rotate, thereby driving the storage bucket 111 and the contrast medium test tube 113 to rotate clockwise. The fixing ring 112 moves forward to drive the contrast medium test tube 113 and the sealing cover 27 to move forward. The movement of the sealing cover 27 drives the second gear 24 to move forward. Because the second gear 24 is meshed with the second rack 25, the movement of the second gear 24 drives the second gear 24 to rotate counterclockwise. The counterclockwise rotation of the second gear 24 drives the stirring member 26 to rotate counterclockwise as well. The contrast medium test tube 113 rotates clockwise, and the stirring member 26 inside the contrast medium test tube 113 rotates clockwise. The component 26 rotates counterclockwise, so that the inside and outside of the contrast agent tube 113 move relative to each other, and the contrast agent inside the contrast agent tube 113 can be stirred, thereby generating microbubbles. In the process of the fixed ring 112 extending forward, because the bottom of the fixed ring 112 is in a hollow state, the front of the bottom of the fixed ring 112 will squeeze the bullet block 21, and the bullet block 21 moves downward under the squeezing of the fixed ring 112, and the reset spring 2 is compressed, and the fixed ring 112 continues to move. When the bullet block 21 is located in the hollow position at the bottom of the fixed ring 112, the fixed ring 112 no longer squeezes the bullet block 21, and the reset spring 2 will stretch. The stretching of the reset spring 2 drives the bullet block 21 to move upward, and the upward movement of the bullet block 21 will squeeze and push the fixed ring 112 upward, so that the fixed ring 112 moves upward. When the fixing ring 112 continues to move forward, the bottom rear of the fixing ring 112 will squeeze the bullet block 21 again, and the reset spring 2 will be compressed again. When the rear of the fixing ring 112 is separated from the bullet block 21, the reset spring 2 will extend and drive the bullet block 21 to move upward and reset. When the fixing ring 112 passes through three bullet blocks 21, the fixing ring 112 will be lifted upward. After the fixing ring 112 is lifted upward, it will drop and drive the rotating table 13 to shake up and down. The shaking of the rotating table 13 will drive the contrast agent inside the rotating table 13 to shake up and down to generate microbubbles. In this way, when the fixing ring 112 moves forward, the contrast agent tube 113 will rotate, and the stirring member 26 located in the contrast agent tube 113 will also rotate. The two rotate at the same time to stir the contrast agent to generate microbubbles.In addition, the bullet 21 will also cause the injection to shake up and down to generate microbubbles.

[0038] like Figure 8 and Fig. 9 As shown, it also includes a clamping mechanism for clamping the blind 11, the clamping mechanism includes a screw 3, a connecting rod 31, a belt 32, a fixed block 33, a connecting block 34, a first fixed frame 35, a second telescopic rod 36 and a rotating rod 37, the first fixed frame 35 is respectively fixedly connected to the left and right sides of the storage box 1, the second telescopic rod 36 is fixedly connected to the inner side of the first fixed frame 35, the screw 3 is respectively fixedly connected to the telescopic end of the second telescopic rod 36, the blind 11 is squeezed and matched with the screw 3, and the connecting rod 31 is The first and second telescopic rods 36 are rotatably connected to the first fixed frame 35, the second telescopic rod 36 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 front side of the bottom of the storage box 1, the belt 32 is respectively wound between the rotating rod 37 and the connecting rod 31 through the transmission wheel, the connecting blocks 34 are respectively fixedly connected to the rotating rod 37 near the belt 32, the fixed block 33 is fixedly connected between the two connecting blocks 34, and the fixed block 33 is squeezed and matched with the blind 11.

[0039] When the contrast agent is in the storage state, because the external environment is changeable, the curtain 11 may be torn open due to wind and accidental contact, which may easily cause the contrast agent to be exposed to the sun and cause degradation reaction. Therefore, it is necessary to set a clamping mechanism to clamp the curtain 11. When the contrast agent is not needed, the staff manually rotates the fixed block 33 upwards. The upward rotation of the fixed block 33 will gradually contact and squeeze the curtain 11. The rotation of the fixed block 33 will drive the connecting block 34 to rotate. The rotation of the connecting block 34 will drive the rotating rod 37 to rotate. The rotation of the rotating rod 37 will cause the belt 32 to rotate. The rotation of the belt 32 drives the connecting rod 31 to rotate. The rotation of the connecting rod 31 will drive the inner side of the screw rod 3 to move. The movement of the screw 3 will drive the telescopic end of the second telescopic rod 36 to move inward. The screw rods 3 are all moved inward until the two screw rods 3 are connected. At this time, the screw 3 is located at the rear and lower position of the curtain 11, and the fixed block 33 is located at the front and lower position of the curtain 11. At this time, the screw 3 and the upward rotating fixed block 33 will squeeze the curtain 11 together The rotation of the connecting block 34 will drive the belt 32 to rotate in the opposite direction to the previous direction, and the belt 32 will drive the connecting rod 31 to rotate, and the connecting rod 31 will drive the screw 3 to move in the direction close to the first fixed frame 35, and the movement of the connecting rod 31 will squeeze the second telescopic rod 36, so that the telescopic end of the second telescopic rod 36 also moves in the direction close to the first fixed frame 35 to reset. When the screw 3 moves outward and resets first, the screw 3 no longer contacts and squeezes the rear of the curtain 11, and the curtain 11 can be opened. The contrast agent test tube 113 moves forward to open the curtain 11, so that the contrast agent test tube 113 can be extended from the storage box 1. In this way, when the contrast agent is not needed, the screw 3 will connect the curtain 11 in series to prevent the external environment from opening the curtain 11, causing the contrast agent to contact with sunlight.

[0040] like Figure 10-12 As shown, it also includes a splitting mechanism for snapping off the sealing cover 27 and the contrast agent tube 113, the splitting mechanism includes a guide plate 4, a telescopic member 41, a second fixing frame 42, a third rack 43 and a fixing member 44, the three fixing members 44 are respectively fixedly connected to the inner rear side of the storage box 1, and the front end of the fixing member 44 is provided with an inclined block. Three groups of guide plates 4 are fixedly connected to the inner rear side of the storage box 1, each group includes an upper and lower guide plate 4, the third rack 43 is respectively slidably connected between the upper and lower guide plates 4, the third rack 43 and the first gear 23 are meshed with each other, the telescopic members 41 are fixedly connected in front of the third rack 43, the second fixing frame 42 is fixedly connected to the upper end of the telescopic member 41, the second fixing frame 42 is snap-fitted with the sealing cover 27, and the second fixing frame 42 is squeezed with the inclined block of the fixing member 44.

[0041] When contrast agent is needed, the fixing ring 112 will drive the contrast agent to move forward, and the staff needs to pull out the sealing cover 27 to absorb the contrast agent into the syringe. It takes time for the staff to pull out the sealing cover 27. During this period of time, the contrast agent will come into contact with sunlight and be easily decomposed. Therefore, a splitting mechanism is provided to pull the sealing cover 27 out of the contrast agent tube 113. As mentioned above, when the contrast agent moves forward, the first gear 23 will rotate clockwise, and the rotation of the first gear 23 will drive the third rack 43 to move rightward. The movement of the third rack 43 will drive the telescopic member 41 and the second fixing frame 42 to move rightward. The movement of the second fixing frame 42 to the right will engage with the sealing cover 27, and the contrast agent tube 113 will continue to move forward. The forward movement of the contrast agent tube 113 will drive the second fixing frame 42 to move forward as well. At this time, the telescopic end of the telescopic member 41 also extends forward. During the forward movement of the second fixing frame 42, the second fixing frame 42 will engage with the inclined surface block of the fixing member 44. The second fixing frame 42 is lifted up by the pressing action of the inclined plane block. Since the second fixing frame 42 is engaged with the sealing cover 27, the lifting of the second fixing frame 42 drives the sealing cover 27 to be pulled out of the contrast medium test tube 113. Then, the contrast medium test tube 113 continues to move forward and is removed from the blind 11. The staff can take the contrast medium test tube 113 out of the storage barrel 111, remove the pulled-out sealing cover 27, and then use a syringe to absorb the contrast medium test tube 113. When new contrast agent needs to be stored in the storage box 1, the staff can pull the telescopic member 41 to the left, so that the telescopic member 41 drives the third rack 43 to move to the left and reset, and then the fixing ring 112 can be pushed backward to reset, and the third rack 43 will re-engage with the first gear 23. In this way, the sealing cover 27 can be pulled out of the contrast agent tube 113 during the process of moving the contrast agent tube 113 forward, saving manpower and reducing the exposure time of the contrast agent to the sun.
