[0002] Stem cells are a type of cell with unlimited or immortal self-renewal capabilities and can produce at least one type of highly differentiated daughter cells. Currently, most biologists and medical scientists believe that stem cells are a type of cell that comes from embryos, fetuses or adults and has unlimited self-renewal, proliferation and differentiation capabilities under certain conditions. They can produce daughter cells with exactly the same phenotype and genotype as themselves, as well as specialized cells that make up the body's tissues and organs, and can also differentiate into progenitor cells.
[0003] At present, when stem cells are extracted and produced, the stem cell raw materials need to be pretreated first, and screening the raw materials is one of the pretreatments. However, the existing extraction devices do not have the screening function, and are unable to screen and collect the materials, cannot meet the needs of users, and reduce the practicality of the extraction devices. Therefore, there are deficiencies and cannot meet the needs of users. Therefore, further improvement is necessary.
[0004] Therefore, in view of this, research and improvement are conducted on the existing structures and deficiencies, and a stem cell extraction device with screening function is provided, in order to achieve a more practical purpose. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a stem cell extraction device with screening function, which is achieved by the following specific technical means:

[0008] By adopting the above structure, the driving motor drives the crushing blade to rotate synchronously, so that the high-speed rotating crushing blade collides and crushes the stem cell raw material in the inner cylinder, thereby realizing the crushing operation of the raw material.
[0009] Furthermore, the screen barrel group includes an outer screen barrel and an inner screen barrel, and the lower side of the adjustment part is movably connected to the outer screen barrel and the inner screen barrel.
