Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, in particular to a rapid-mixing drug component dilution device. Background Art

[0002] In order to ensure the stability of drug quality and meet clinical needs, some drugs need to be diluted during use and storage. When diluting drugs, a rapid mixing device is used to mix and dilute the drugs. Rapid mixing can evenly blend high-concentration drugs and solvents in a short time, ensuring that the concentration of the diluted drug solution is accurate and the distribution of components is uniform. At the same time, the mixing process reduces human intervention and reduces the risk of cross-contamination.

[0003] However, in the prior art, when traditional mixing equipment mixes and stirs two-phase or multi-phase fluids containing solid particles, liquid droplets, etc., phase separation is likely to occur during the flow process due to the difference in physical properties of different phases. Solid particles may precipitate and accumulate, and liquid droplets may aggregate, especially for high-viscosity pharmaceutical ingredients, resulting in the inability of the fluid in these areas to flow normally, forming dead zones, requiring extended mixing time, resulting in reduced mixing efficiency.
