Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of immune cell extraction auxiliary device, especially to an immune cell extraction structure. BACKGROUND

[0002] Immune cells refer to cells involved in or related to immune response. They include lymphocytes, dendritic cells, monocytes / macrophages, granulocytes, mast cells, etc. Immune cells can be divided into many types, and various immune cells play an important role in the human body. Immune cells (immune cells) are commonly known as white blood cells, including innate lymphocytes, various phagocytes, and lymphocytes that can recognize antigens and produce specific immune responses. General immune cells need to be separated and extracted, and the separation method is mostly using a centrifuge, but multiple test tubes are difficult to move simultaneously, and moving in steps prolongs the process, which can easily contaminate the immune cells or cause the immune cells to differentiate during the process, reducing the quality of the immune cells.

[0003] A stem cell extraction device is disclosed in Chinese Patent No. CN220537783U, authorized on February 27, 2024, in the field of stem cell extraction technology. It includes an extraction table, a stem cell storage test tube, and a stem cell extraction mechanism. The top of the extraction table is provided with a mounting plate, and the mounting plate is provided below with a mounting assembly. The mounting assembly includes a mounting disc, an arc-shaped support plate one, and an arc-shaped support plate two. The bottom of the mounting disc is fixedly connected with a support strip. The inside of the arc-shaped support plate one is provided with a connecting groove. The top and bottom of the connecting groove inner wall are both provided with a recess. One side of the arc-shaped support plate two is fixedly connected with a fixed block. The top and bottom of the fixed block are both fixedly connected with an elastic ball. The fixed block is driven out of the connecting groove by the assistance of two adjusting pieces. The elastic ball is separated from the recess. The arc-shaped support plate two is pushed away to remove and replace the stem cell extraction mechanism. It is convenient to quickly disassemble and replace the stem cell extraction mechanism for the next use after the completion of a round of stem cell extraction. The utility model has the disadvantages that the whole device cannot be moved after centrifugal separation, which can easily contaminate the cells and reduce the quality of the cells.
