Description

Technical Field

[0001] The utility model relates to the technical field of mixing and stirring, in particular to a proportional mixing device for preparing bionic blood for in vitro simulation experiments. Background Art

[0002] In vitro simulation experiments play a vital role in biomedical research, drug screening, medical device testing, and the diagnosis and treatment of cardiovascular diseases. These experiments usually require a fluid medium that can simulate the characteristics of human blood, namely bionic blood. Bionic blood not only requires its physical properties such as density and viscosity to be close to real blood, but also needs to have stable chemical properties and good fluidity to ensure the accuracy and reliability of the experimental results.

[0003] However, traditional methods for preparing bionic blood often have many shortcomings. For example, although some methods can prepare liquids with density and viscosity close to blood, their preparation process is complicated, costly, and difficult to accurately control the proportion of each component, resulting in large fluctuations in the performance of bionic blood. In addition, some bionic blood will stratify and precipitate during long-term storage or use, further affecting its use effect.

[0004] In the prior art, although some proportion mixing devices have been applied in the chemical industry, food industry and other industries, there are relatively few special devices for bionic blood preparation. These devices often cannot fully meet the special requirements of bionic blood preparation in terms of raw material selection, proportion control, mixing effect and other aspects.

[0005] Therefore, developing a proportion mixing device specifically for preparing bionic blood for in vitro simulation experiments has important practical significance and application prospects. Utility Model Content
