Description

Technical Field

[0001] The utility model belongs to the technical field of injection filling, in particular to a filling mechanism for the production of iohexol injection. Background Art

[0002] Iohexol injection, a Western medicine name. It is a contrast agent. It is used for cardiovascular angiography, arteriography, urography, venography, CT enhanced examination; cervical, thoracic and lumbar spinal canal angiography, CT cisternography after spinal subarachnoid injection; arthrography, endoscopic pancreaticocholangiography (ERCP), hernia or fistula angiography, hysterosalpingography, sialography, percutaneous hepatocholangiography (PTC), sinusography, gastrointestinal angiography and "T" tube angiography, etc. When manufacturing iohexol injection, a filling device is needed to fill the bottle and then seal it. When the existing filling device is filling, when the filling machine's storage bottom is floating, it will affect the change of the filling volume, resulting in unstable filling volume.

[0003] The publication number is CN211847120U, which is a filling mechanism for the production of iohexol injection. Through the annular distribution transmission assembly and the multi-injection head injection assembly, multiple bottles can be injected in stages at one time. The injection head integrates the defoaming and vacuuming functions. The injection head uses the vacuuming of the injection head to absorb the bottle filling, and the vacuum state in the bottle is used to absorb the liquid of the corresponding liquid level from the tube body, reducing the amount of content injected into the bottle and the cleanliness affected by the gas. However, there is still no significant improvement in the stability of its filling volume. Utility Model Content

[0004] The utility model aims to provide a filling mechanism for the production of iohexol injection to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filling mechanism for the production of iohexol injection, comprising a filling cylinder for containing iohexol injection, a platform plate is arranged below the filling cylinder, and bottle limiting parts for placing bottles are arranged on both sides of the top of the platform plate, a plurality of quantitative covers are installed on the inner bottom of the filling cylinder, and a plurality of liquid inlet slots are opened on the outer periphery of the quantitative covers, a filling port is opened at the center position of the plurality of quantitative covers at the bottom of the filling cylinder, and the inner periphery of the filling port is blocked with a sealing head, a side pressure stopper is adapted to be arranged on the inner side wall of the quantitative cover, and the lower half of the side pressure stopper passes through the filling cylinder, a pressure piece is arranged on the inner upper half of the inner periphery of the side pressure stopper, and a bottle support for positioning and leaning is arranged at the bottom end of the side pressure stopper.

[0006] In a further embodiment, the upper half of the side pressure stopper is designed as a circular ring and matches the inner wall of the quantitative cover, and the lower half of the side pressure stopper is designed as a plurality of semi-arc plates.

[0007] In a further embodiment, a center plate is provided on the upper half of the inner periphery of the side pressure stopper, and an extension block is fixed to the outer periphery of the center plate and the inner wall of the side pressure stopper.

[0008] In a further embodiment, the pressure piece is composed of a ferrule and a plug rod that are mortised to each other and a pressure spring, and the bottom end of the plug rod is connected to the sealing head.

[0009] In a further embodiment, the bottom of the center plate is fixed to the ferrule, and the pressure spring is located between the ferrule and the plug rod.

[0010] In a further embodiment, a rubber layer for strengthening the seal is bonded to the outer periphery of the side pressure stopper, and a top pressure spring is arranged between the top of the center plate and the quantitative cover.

[0011] In a further embodiment, a limit block for height limitation is bonded to the center of the inner periphery of the side pressure stopper, and the bottle support is annular and has a groove adapted to the bottle mouth at the bottom.

[0012] In a further embodiment, a lifting plate is provided below the platform plate, and lifting devices are installed at the four bottom corners of the lifting plate.

[0013] In a further embodiment, an inner groove is formed on the top of the lifting plate and is rotatably connected to a threaded rod, and a nut seat matching the inner groove is sleeved on the outer periphery of the threaded rod.

[0014] In a further embodiment, the nut seat is fixed to the platform plate, and one end of the threaded rod is connected to a driving motor.

[0015] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0016] The fixed space volume design inside the quantitative cover and the design of the liquid inlet notch enable quantitative function to be achieved. The corresponding design of multiple side pressure baffles and multiple bottle limiting parts for placing the bottle body facilitates filling. The through-tenon joints of multiple semi-arc plates in the lower half of the side pressure baffle and the design of the outer rubber layer enable the side pressure baffle to have a blocking effect. When the side pressure baffle moves, the liquid inlet notch can be blocked. With the help of the top pressure spring, the side pressure baffle can be kept pressed down, which is convenient for liquid to enter the liquid inlet notch.

[0017] The cooperation between the lifting plate and the lifting device can make the bottle body rise to push against the bottle support and the side pressure stopper to close the liquid inlet slot. At the same time, the mortise and tenon design of the ferrule and the plug rod and the elastic restoring force of the pressure spring make the head remain closed to the filling port before the side pressure stopper closes the liquid inlet slot. When the liquid inlet slot is closed, the ferrule and the plug rod are extended to the limit and continue to rise, so that the head is separated from the filling port to achieve filling.

[0018] The filling mechanism for the production of iohexol injection can accurately control the filling volume, so that the stability of the filling volume is guaranteed, and the overall design is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The bottom of the filling cylinder 1 is provided with a plurality of filling ports 8, which are arranged in an array. The inner bottom of the filling cylinder 1 is provided with a plurality of quantitative covers 5, which are selected to match the volume space according to the requirements so as to correspond to the bottle body. The outer periphery of the quantitative cover 5 is provided with a plurality of liquid inlet slots 6;

[0035] See also Figures 3 to 5 In order to realize automatic blocking, a side pressure stopper 7 is provided on the inner periphery of the quantitative cover 5. The upper half of the side pressure stopper 7 is designed as a circular ring and matches the inner wall of the quantitative cover 5. The lower half of the side pressure stopper 7 is designed as a plurality of semi-arc plates. The semi-arc plates penetrate the bottom of the filling cylinder 1. The outer periphery of the side pressure stopper 7 is bonded with a rubber layer for strengthening the seal.

[0036] A center plate 11 is provided on the upper half of the inner periphery of the side pressure stopper 7, and extension blocks 12 are fixed to the outer periphery of the center plate 11 and the inner wall of the side pressure stopper 7. The inner periphery center of the side pressure stopper 7 is connected to a limit block 14, and the limit block 14 plays a role of height limit. A top pressure spring 10 is provided between the top of the center plate 11 and the quantitative cover 5. The elastic force of the top pressure spring 10 presses the side pressure stopper 7 downward, so that the liquid inlet slot 6 can be filled with liquid;

[0037] A bottle support 13 is connected between the bottoms of the multiple semi-arc plates at the bottom end of the side pressure stopper 7. A groove adapted to the bottle mouth is provided at the bottom of the bottle support 13. A lifting plate 15 is provided below the platform plate 3. Lifting devices 16 are installed at the four corners of the bottom of the lifting plate 15. The lifting device 16 can be a hydraulic column or the like.

[0038] When the lifting device 16 is running, the platform plate 3 is driven to rise, so that the bottle body pushes against the bottle holder 13, so that the side pressure stopper 7 rises and the liquid inlet slot 6 is closed, and the quantitative process can be realized;

[0039] In order to ensure the stability of the quantitative process, a ferrule 31 is connected to the bottom of the center plate 11, and a plug rod 32 is mortised at the bottom end of the ferrule 31.

The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0043] How it works

[0044] When the filling mechanism for the production of iohexol injection is needed, the iohexol injection is fed into the interior of the filling cylinder 1 through the feed pipe 2, and the iohexol injection is fed into the interior of the quantitative cover 5 through the liquid inlet notch 6. Since the internal space storage of the quantitative cover 5 is fixed, and the horizontal surface of the iohexol injection does not exceed the quantitative cover 5, it can be ensured that the quantitative cover 5 can be fully filled each time to achieve quantitative measurement;

[0045] The bottle containing the iohexol injection is placed above the bottle limiting portion 4, and the driving motor 21 is started to drive the threaded rod 22 to rotate, so that the nut seat 23 drives the platform plate 3 to move, so that the bottle is in a corresponding position with the multiple injection ports 8;

[0046] Start the lifting device 16, drive the platform plate 3 to rise, make the bottle mouth of the bottle body push against the bottle holder 13, make the top pressure spring 10 compress, and the side pressure block 7 gradually rises. When it rises to block and close the liquid inlet slot 6, the ferrule 31 and the plug rod 32 also reach the limit of expansion and extension. When the side pressure block 7 rises again, the sealing head 9 can be separated from the filling port 8, and the iohexol injection solution inside the quantitative cover 5 can be input into the bottle body to complete the filling;

[0047] After completion, the lifting device 16 descends, and through the elastic force of the pressure spring 33 and the top pressure spring 10, the filling port 8 and the sealing head 9 are closed, and the liquid inlet slot 6 is opened, and the next filling can be carried out.
