Description

Technical Field

[0001] The utility model relates to the technical field of cell culture equipment, in particular to an automatic NK cell culture equipment. Background Art

[0002] NK cells, or Natural Killer cells, are an important type of cell in the human immune system. They are a type of lymphocytes and are mainly found in the blood, lymphatic tissues, and certain organs. The main function of NK cells is to recognize and kill virus-infected cells and certain cancer cells. Unlike T cells, which need to recognize specific antigens in advance, NK cells can directly recognize and attack abnormal cells, so they are called "natural" killers.

[0003] NK cell therapy, full name natural killer cell therapy, is an important category of tumor immunotherapy and a form of adoptive cell therapy. NK cell therapy uses mononuclear cells separated from the patient's own peripheral blood cells, amplified and activated in vitro, and then intravenously infused to kill tumor cells by activating the body's specific immune response.

[0004] However, existing culture equipment requires multiple groups of cells to be placed in the same spatial environment for culture at the same time. This requires opening the culture equipment when taking a single group of cells. This process can easily expose other groups of cells to the air, increasing the possibility of contamination and thus leading to the death of the cultured cells. Utility Model Content
