[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. The stem cell separation and extraction device is a centrifuge developed for separation, purification and transplantation of stem cells. It is mainly used in clinical treatment and beauty equipment. The centrifugal force of the stem cell separation and extraction device has high precision, which can improve the efficiency of stem cell separation and extraction.

[0003] After searching, the authorization announcement number CN217973194U discloses a separation and extraction device for stem cells, which specifically relates to the field of stem cell technology, including a separation tank and an upper cover located above the separation tank, a motor is fixedly installed at the bottom of the separation tank, the output end of the motor is fixedly connected to a connection plate through a rotating shaft, a fixed sleeve is fixedly connected to the center of the top of the connection plate, and the outer surface of the fixed sleeve is sequentially sleeved with a plurality of positioning sleeves, and the outer surface of each positioning sleeve is fixedly connected to a carrier plate. This design enables the stem cell separation and extraction device to achieve the overall removal of the carrier plate through the mutual cooperation of the positioning sleeve, the fixed sleeve, the carrier plate and the positioning plate, and can produce positioning rings of different calibers and the clamping mechanism on the positioning ring according to actual conditions, which is convenient and better suitable for test tubes of different sizes.
