Description

Technical Field

[0001] This utility model relates to the field of cell filtration technology, specifically to an immune cell filtration device. Background Technology

[0002] Cell filtration is a widely used technique in biological and medical research. It utilizes cell sieves or filters to filter cell samples, selecting single-cell suspensions of the target cell size and removing any cell clusters or debris, thereby improving the accuracy of experimental results. Cell sieves are typically made of a combination of a polypropylene frame and a special nylon mesh, and are commonly available in three mesh sizes: 40μm, 70μm, and 100μm, to meet the filtration needs of different cell sizes. The pores of cell filters are specially processed using a laser drilling machine, resulting in advantages such as no burrs, no sealing edges, no residue, and smooth cuts.

[0003] Immune cell filtration requires filters. Existing filters can usually only filter single cells. When multiple cells are present in the solution, they cannot be separated efficiently, which requires multiple separations of cells, reduces the efficiency of cell extraction, and is not conducive to use by users.

[0004] Therefore, the cell filter needs to be redesigned and modified to effectively prevent the problems existing in the background technology. Utility Model Content
