Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for human stem cell technology research. Background Art

[0002] Human stem cells are a type of cell with unlimited or immortal self-renewal ability and can produce at least one type of highly differentiated daughter cells. The function of stem cell populations is to control and maintain cell regeneration. They have limited expansion capacity and restricted differentiation potential. The function of these cell populations is to increase the number of differentiated cells produced after each division of stem cells. Research on human stem cell technology often requires sampling of stem cells.

[0003] When sampling, stem cells must first be separated from the blood. When traditional stem cells are separated and sampled, it is usually necessary to first use an oscillator to oscillate the stem cells. After the oscillation is completed, the test tube needs to be taken out and the stem cells need to be centrifuged using a centrifuge. As a result, when separating stem cells, not only multiple devices need to be used, but the operation steps are also cumbersome, which increases the difficulty of the experimenter's work and is inconvenient to use. For this reason, we propose a sampling device for human stem cell technology research. Utility Model Content
