Description

Technical Field

[0002] In the prior art, through retrieval, it is found that the Chinese patent discloses a "fully sterile liquid mixing tank", and its publication number is "CN217313254U". This patent mainly realizes the input of the raw material liquid by configuring a pneumatic balance mechanism for the liquid mixing tank and cooperating with an injection mechanism, so that the liquid mixing tank is in a sealed state during the whole raw material input process, avoiding bacteria from entering the liquid mixing tank during feeding and contaminating the raw material liquid, improving the ability of the liquid mixing tank to isolate bacteria, and ensuring the completion of the liquid mixing process without the need for the whole liquid mixing tank to be in a sterile environment

[0003] Fully sterile, greatly reducing the cost of achieving sterile conditions.

[0004] However, when the above device prepares the liquid medicine, it does not fully stir and mix the two mixed liquid medicines, which will lead to uneven mixing, thus affecting the effectiveness and safety of the medicine. Since the physical properties such as density and viscosity of the two liquid medicines may be different, without sufficient stirring, the lighter liquid medicine may float on the top, while the heavier liquid medicine deposits at the bottom, resulting in uneven concentration of the final liquid medicine. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fully sterile liquid mixing tank, which effectively improves the mixing efficiency of the antibody liquid medicine by setting a mixing mechanism, ensuring the uniformity and stability of the antibody liquid medicine, and solving the problem that when the above device prepares the liquid medicine, it does not fully stir and mix the two mixed liquid medicines, which will lead to uneven mixing.

[0030] The rotating assembly includes a tank cover 21 arranged above the liquid mixing tank 1. A hollow pipe 22 is rotatably penetrated through the tank cover 21. The inner wall of the liquid mixing tank 1 is fixedly connected with a fixed disc 4. The bottom end of the hollow pipe 22 extends rotatably to the bottom surface of the fixed disc 4. The bottom end of the hollow pipe 22 is fixedly connected with a connecting disc 23. The outer wall of the connecting disc 23 is rotatably connected with a shunt pipe 24. A plurality of hollow pipes 25 are communicated with the outer wall of the shunt pipe 24. The top surface of the shunt pipe 24 is rotatably connected with the bottom surface of the fixed disc 4. The mixing assembly includes a plurality of openings 26 respectively opened on the outer walls of the plurality of hollow pipes 25. Two limiting rings 27 are fixedly connected to the outer wall of the hollow pipe 22. The two limiting rings 27 are respectively slidably connected with the top surface and the bottom surface of the tank cover 21. The driving assembly includes a fixed frame 28 fixedly connected to the top surface of the tank cover 21. A motor 29 is fixedly connected to the fixed frame 28. The output end of the motor 29 is fixedly connected with a rotating rod 291. The bottom end of the rotating rod 291 is fixedly connected with a first gear 292. A second gear 293 is fixedly connected to the outer wall of the hollow pipe 22. The first gear 292 meshes with the second gear 293. The second gear 293 is slidably connected with the top surface of the fixed disc 4. By arranging the mixing mechanism 2, after the liquid in the hollow pipe 22 is distributed into a plurality of hollow pipes 25 through the shunt pipe 24, the rotating hollow pipes 25 are ejected at high speed through a plurality of openings 26 under the action of centrifugal force, forming a fine liquid droplet flow. These high-speed ejected liquid droplet flows meet another liquid. During the high-speed collision process, the two liquids penetrate and blend with each other, being fully mixed together to form a uniform mixed liquid. This efficient mixing method effectively improves the mixing efficiency of the antibody liquid medicine and ensures the uniformity and stability of the antibody liquid medicine.

[0031] The conveying mechanism 3 includes a cleaning component and a conveying component. The cleaning component includes a connecting rod 31 fixedly connected to the bottom surface of the shunt pipe 24. A plurality of cleaning brushes 32 are fixedly connected to the outer wall of the connecting rod 31. The plurality of cleaning brushes 32 are all in contact with the inner wall of the liquid preparation tank 1. The conveying component includes a liquid inlet pipe 33 communicatively arranged on the outer wall of the liquid preparation tank 1.

Two bolts 37 are threadedly connected between the liquid preparation tank 1 and the tank cover 21. A plurality of support legs 36 are fixedly connected to the bottom surface of the liquid preparation tank 1. Two handles 38 are fixedly connected to the top surface of the tank cover 21. By providing the conveying mechanism 3, after the liquid medicine is prepared, the cleaning liquid can be poured into the interior of the liquid preparation tank 1 through the hollow pipe one 22 and the liquid inlet pipe 33 to thoroughly clean the liquid preparation tank 1. The synchronous rotation of the cleaning brushes 32 can effectively remove the residual liquid medicine on the inner wall of the liquid preparation tank 1, avoiding cross-contamination and affecting subsequent liquid medicine preparation. The design of the hollow pipe one 22 and the liquid inlet pipe 33 ensures that the cleaning liquid can be evenly sprayed onto all corners of the liquid preparation tank 1, ensuring the cleaning effect. This design effectively improves the cleaning efficiency of the liquid preparation tank 1, guarantees the quality and safety of the liquid medicine, and avoids cross-contamination between liquid medicines.

[0032] A specific application of this embodiment is: by providing the mixing mechanism 2, the two limit rings 27 and the fixed disk 4 cooperate with each other to enable the hollow pipe one 22 to only rotate on the tank cover 21, supporting the rotating hollow pipe one 22. Before preparing the antibody liquid medicine, two different liquid medicines can be respectively poured into the interior of the liquid preparation tank 1 through the hollow pipe one 22 and the liquid inlet pipe 33. At the same time, the driving motor 29 drives the rotating rod 291 and the gear one 292 to rotate, and drives the hollow pipe one 22 to rotate under the cooperation of the gear two 293. After the liquid in the hollow pipe one 22 is distributed to a plurality of hollow pipes two 25 through the shunt pipe 24, the rotating hollow pipes two 25 are ejected at high speed through a plurality of openings 26 under the action of centrifugal force, forming a fine liquid droplet flow. These high-speed ejected liquid droplet flows meet another liquid, and during the high-speed collision process, the two liquids penetrate and blend with each other, fully mixing together to form a uniform mixed liquid. This efficient mixing method effectively improves the mixing efficiency of the antibody liquid medicine, ensuring the uniformity and stability of the antibody liquid medicine;

[0033] By providing a conveying mechanism 3, during the rotation of the first hollow tube 22, the connecting rod 31 rotates synchronously therewith, enabling multiple cleaning brushes 32 to scrape the inner wall of the liquid dispensing tank 1, preventing the liquid medicine from adhering to the inner wall of the liquid dispensing tank 1. After the liquid medicine is formulated, the cleaning liquid can be introduced into the interior of the liquid dispensing tank 1 through the first hollow tube 22 and the liquid inlet pipe 33 to thoroughly clean the liquid dispensing tank 1. The synchronous rotation of the cleaning brushes 32 can effectively remove the residual liquid medicine on the inner wall of the liquid dispensing tank 1, avoiding cross-contamination and affecting subsequent liquid medicine formulation. The design of the first hollow tube 22 and the liquid inlet pipe 33 ensures that the cleaning liquid can be evenly sprayed into every corner of the liquid dispensing tank 1, ensuring the cleaning effect. This design effectively improves the cleaning efficiency of the liquid dispensing tank 1, guarantees the quality and safety of the liquid medicine, and avoids cross-contamination between liquid medicines. The liquid inlet pipe 33 and the liquid outlet pipe 34 cooperate with each other to regulate the liquid outlet speed. Multiple bolts 37 cooperate with each other to seal the inner wall of 21 to form a sterile environment, and at the same time enable the tank cover 21 to be quickly disassembled, facilitating the maintenance of the internal parts of the liquid dispensing tank 1.
