Background

Cancer is one of the leading causes of death in humans. Studies have shown that at least 30% of deaths are preventable if cancer patients are diagnosed and treated before metastatic cancer occurs. When Circulating Tumor Cells (CTCs) flow from a primary or metastatic tumor into the peripheral blood, the tumor undergoes metastasis. Therefore, the isolation of tumor cells from circulating blood by CTC examination is of great importance for the diagnosis of cancer and the evaluation of therapeutic efficacy during cancer treatment.

After the cell separation device separates the target cells from the blood sample, the target cells are usually collected in a container of the same size regardless of the amount of the separated target cells; and then distributing the collected target cells according to the requirement of subsequent detection. This results in cumbersome operation, low efficiency, and loss of target cells during the secondary distribution.
