Description

Technical Field

[0001] This utility model relates to the field of biological agent equipment technology, specifically a stirring assembly for biological agent preparation. Background Technology

[0002] Chinese patent document CN208449116U discloses a stirring device for biopharmaceuticals. It proposes a mixer, a machine with a bladed shaft rotating in a cylinder or tank to mix multiple raw materials into a mixture or a suitable consistency. In biopharmaceutical manufacturing, mixers are needed to ensure uniform mixing of different drugs. However, current mixers on the market cannot achieve uniform mixing of various drugs, resulting in uneven drug content and posing a significant risk to patients. The solution involves a top drive shaft connected to a stirring drive shaft near the top of the tank's internal cavity via a differential gear. This difference in rotation speed between the top drive shaft and the stirring drive shaft, along with the different rotation speeds of the stirring frame and the spiral stirring blades, allows the drugs to rub against each other due to the speed difference, enabling them to self-mix and achieve uniformity.

[0003] The above-mentioned solutions and existing technologies address the issue that some existing stirring devices cannot effectively mix biological agents during the stirring process. As a result, some reagents are still not mixed evenly during use, which affects the use of the agent and reduces its effectiveness, thus failing to meet actual usage requirements.

[0004] Therefore, this invention proposes a stirring assembly for the preparation of biological agents to solve the above problems. Utility Model Content
