Description

Technical Field

[0001] The present invention relates to the technical field of cell sorting, in particular to a cell sorting device for flow cytometry detection. Background Art

[0002] Flow cytometry is a modern cell analysis technology device that can perform qualitative or quantitative detection of various properties and functional states of cells and achieve cell separation. It is widely used in the quantitative analysis and sorting of single cells or other biological particles. It has analysis and sorting functions and can support a wide range of scientific research applications, such as lymphocyte subset counting, stem cell counting, leukemia residual and reticulocyte counting, etc. It is also equipped with an intuitive software system to realize the process of many applications.

[0003] However, when using the existing cell detection sorting instruments, the detection personnel mostly collect the cell fluid in the working chamber of the sorting instrument by holding a test tube. The hand-held test tube for collecting cell fluid is easy to shake and has poor stability, which can easily cause the cell fluid to spill and waste the cell fluid. In addition, when sorting a large number of cells, the detection personnel need to constantly change the test tube to collect the cell fluid. The process is relatively cumbersome and affects the detection personnel's other work progress. Secondly, after the existing cell detection sorting instrument is used, the working chamber is in an exposed state, which is easy to cause contamination after cleaning. It also needs to be cleaned during use, which increases the work intensity of the detection personnel and affects the collection progress of the cell fluid. In view of the above problems, the inventor proposes a cell sorting device for flow cytometry detection to solve the above problems. Summary of the invention
