Abstract
Description
Technical Field
[0001] This utility model relates to the field of inactivated vaccine mixing technology, and in particular to an oil adjuvant inactivated vaccine mixing device. Background Technology
[0002] Inactivated vaccines are vaccines made by first culturing viruses or bacteria and then inactivating them with heat or chemical agents (usually β-propiolactone or formalin). Inactivated vaccines can be composed of whole viruses or bacteria or fragments of them, which are called split vaccines. The production of split vaccines involves further purifying the microorganisms until the vaccine contains only the required antigenic components (such as pneumococcal polysaccharides). It can be either a protein vaccine or a polysaccharide vaccine. Protein vaccines include toxoids (inactivated bacterial toxins) and subunit vaccines.
[0003] The production process of inactivated vaccines involves cultivation, inactivation, purification, formulation, filling, and packaging. Formulation involves mixing the vaccine stock solution in a suitable ratio before filling, but this method results in a relatively long time interval between these steps. Therefore, current technology typically involves directly placing the formulated vaccine stock solution into the filling device for mixing before completing the filling operation, thereby reducing the subsequent production time of the vaccine stock solution.
[0004] However, the vaccine containers of existing inactivated vaccine mixing equipment are not easy to clean. After each filling, there will be vaccine residue at the bottom of the container, causing unnecessary waste. In addition, the height of the stirring blades of the existing mixing equipment cannot be adjusted, which cannot adapt to different mixing needs, resulting in poor versatility of the equipment.

The stirring rod 6 is engraved with scale markings (not shown in the figure), allowing the user to accurately adjust the height of the stirring rod 6 to adapt to different mixing needs, thus improving the versatility of the equipment. During mixing, the stirring motor 11 drives the stirring rod 6 to rotate, and the stirring blades 14 stir the vaccine in the mixing tank 2, while simultaneously heating the cavity 1 of the tank 1. Water is filled into cavity 15, and the water in cavity 15 is heated by heating pipe 16, thereby heating the vaccine in mixing tank 2 in a water bath. After mixing is completed, the user places the vaccine can on weighing instrument 23 and aligns the can opening with the outlet pipe 22. The filling pump 21 draws out the vaccine from mixing tank 2 and fills it into the vaccine can. At the same time, the filling volume is accurately measured by weighing instrument 23. After the set value is reached, the filling pump 21 stops filling. The vaccine in mixing tank 2 will be completely discharged from mixing tank 2 under the guidance of the conical surface, avoiding vaccine residue in mixing tank 2 and thus avoiding waste.
