Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drug mixing device for biomedical research. Background Art

[0002] Biomedicine is an important interdisciplinary field that integrates biology and medicine. It covers a wide range of levels, including molecules, cells, tissues, and organisms, and delves into life phenomena, the structure and function of organisms, and the mechanisms of disease occurrence and development. Drug development requires extensive experiments and testing. Drug mixing devices can prepare drug samples with different formulations, providing researchers with reliable experimental materials. Existing drug mixing devices used in biomedical research contain large particles in the drugs. These large particles increase the difficulty of mixing, making it difficult for drugs of different ingredients to fully contact and mix, reducing uniformity. Furthermore, during the mixing process, drugs may accumulate at the bottom, resulting in reduced mixing effectiveness.
