Description

Technical Field

[0001] The utility model belongs to the technical field of storage, in particular to a storage sealing structure for the production of iopamidol. Background Technique

[0002] Iopamidol injection, with iopamidol as the main component, is a commonly used contrast agent in the radiology department of medicine. Due to the volatility of iopamidol, it is usually sealed with a glass bottle during the actual production process. Most of the existing medical iopamidol storage devices can be resealed after use. When the traditional sealing device encounters external force, it may move or rotate, affecting the sealing effect.

[0003] After retrieval, a storage sealing structure for the production of iopamidol in a Chinese patent document (authorized announcement number CN209973702U) belongs to the technical field of sealed storage. It includes a storage tank. The upper surface of the storage tank is communicated with the lower surface of the bottle mouth. A rubber ring is sleeved on the outer surface of the bottle mouth. Two clamping rods are clamped on the outer surface of the rubber ring. One side of each of the two clamping rods away from each other is connected with a pressing rod. The two pressing rods are respectively movably connected to the left and right side surfaces of the placing plate through pin shafts. A rotating device is clamped on the upper surface of the placing plate. For the storage sealing structure for the production of iopamidol, by setting a slider, a pulley, a placing plate, a threaded rod and a pressing rod, when the staff takes out iopamidol, the storage bottle can be sealed through this sealing mechanism, so that the iopamidol in the storage bottle is not easily in contact with air and volatilizes, and this sealing structure can be recycled, reducing the waste of resources of this sealing structure. Although it can be stably sealed, when the sealing device encounters external force, it may move or rotate, affecting the sealing effect. Content of the Utility Model

Detailed Description of the Invention

[0030] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0031] Unless otherwise defined, the up, down, left, right, front, back, inside and outside directions involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the drawings shown in the present invention, and are hereby explained together.

[0032] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., depending on actual needs.

[0033] Please refer to Figures 1 to 5 As shown, a storage and sealing structure for the production of iopamidol. This embodiment includes:

[0034] A storage bottle 1 for storing the processed iopamidol. The storage bottle 1 is integrally formed with a bottle mouth 2;

[0035] A sealing cover 3. An inner wall of the sealing cover 3 is adhesively bonded with a sealing gasket 4 made of rubber for covering the bottle mouth 2 and performing sealed storage. The thicknesses of the sealing ring 15 and the sealing gasket 4 are selected according to actual needs;

[0036] An outer periphery of the bottle mouth 2 is integrally formed with a convex ring 5. The size of the convex ring 5 is selected according to actual needs. The convex ring 5 is rotatably connected through a rotating shaft to an inverted U-shaped assembly plate 6. A threaded tube 7 is embedded and installed at a top end of the assembly plate 6;

[0037] An adjusting threaded rod 8 is threadedly connected to the threaded tube 7. The adjusting threaded rod 8 is rotatably connected through a bearing to a movable plate 9. An outer periphery of the movable plate 9 is sleeved with a hollow plate 10. A bottom end of the hollow plate 10 is connected to a pressing plate 11 for pressing and fixing the sealing cover 3. A spring 12 is connected between the pressing plate 11 and the movable plate 9. Rotating the adjusting threaded rod 8 causes the pressing plate 11 to press against the sealing cover 3 until the spring 12 is in a contracted state and the sealing gasket 4 and the sealing ring 15 are in a contracted state, thereby ensuring the sealing effect.

[0038] An outer periphery of the adjusting threaded rod 8 is connected to a side support plate 13. A rectangular channel is opened at a top end of the side support plate 13. An L-shaped limiting plate 14 is arranged in the rectangular channel. Two rectangular channels for the limiting plate 14 to pass through are opened at a top end of the assembly plate 6. An elastic sleeve with elasticity is adhesively bonded to an outer periphery of the limiting plate 14. Inserting the limiting plate 14 into the rectangular channel of the assembly plate 6 ensures the stability of the adjusting threaded rod 8 and avoids random movement of the adjusting threaded rod 8. The thread density of the adjusting threaded rod 8 is as dense as possible so that the distance moved in one week is as small as possible, making the influence of rotating the limiting plate 14 by 180 degrees on the distance not significant.

[0039] To improve the sealing performance, a sealing ring 15 made of rubber adapted to the convex ring 5 is adhesively bonded to a bottom end of the sealing cover 3. A rubber plug 16 for plugging the bottle mouth 2 is adhesively bonded to a bottom end of the sealing gasket 4. A rubber sleeve 17 adapted to the bottle mouth 2 is adhesively bonded to an outer periphery of the sealing cover 3.

[0040] To improve the practicability, the shape of the adjusting threaded rod 8 is set to a T shape. Anti-slip threads are opened on an outer periphery of the adjusting threaded rod 8. Anti-slip threads for easy operation are arranged on an outer periphery of the sealing cover 3.

[0041] To improve the tightening effect, two rotating plates 18 are rotatably connected to both sides of the tightening plate 11. The rotating plates 18 have the same thickness and height as the tightening plate 11. The rotating plates 18 are toggled to a direction perpendicular to the tightening plate 11 to improve the tightening effect.

[0042] Working principle

[0043] For the storage sealing structure used in the production of iopamidol, when storage sealing is required, the sealing cover 3 is covered, the assembly plate 6 is rotated to the vertical state, the rotating plate 18 is toggled to a direction perpendicular to the tightening plate, the adjusting threaded rod 8 is rotated so that the tightening plate 11 abuts against the sealing cover 3, and it is rotated until the spring 12 is in a contracted state and the sealing gasket 4 and the sealing ring 15 are in a contracted state, thereby ensuring the sealing effect. Then, the limiting plate 14 is inserted into the rectangular channel of the assembly plate 6 to ensure the stability of the adjusting threaded rod 8 and prevent the adjusting threaded rod 8 from moving randomly.
