A method for automatically producing liquid-based cells

Abstract

The invention relates to a method for automatically preparing liquid-based cell slides, which is applied to pathological slide preparation equipment used in pathological examination. The method comprises the following steps of: cell isolation, filtration and settlement, cell suspension extraction and centrifugation and slide preparation. The method can automatically prepare slides on the same equipment and is high in automation degree, time-saving, labor-saving, quick and efficient. The number of slides can be changed flexibly. The method can be used for preparing a plurality of glass slides in one step, has wide application range, can automatically and accurately determine the cell extraction amount, ensures that the cell layer is thin and good in consistency, enables the background to be clean, and guarantees the uniformity and consistency in cell transfer amount on glass slides.

Description

technical field

[0001] The invention relates to a method for automatically making liquid-based cell slides on pathological slide production equipment used in pathological examination. Background technique

[0002] In the prior art, there are many methods for liquid-based cell sheet production. Such as membrane transfer method, centrifugal smear method, natural sedimentation method and other methods. In order to realize these methods, various equipments are available for matching use. For example, after the centrifugal sedimentation of the cell liquid is carried out with a centrifuge, the cells are then placed on a tablet machine to break up and separate the cells, and then the cell liquid is manually taken out for centrifugal sedimentation. Multiple manual operations. There are also centrifuged on the centrifuge, the cells are broken up and separated by manual operation, and then processed by natural sedimentation. Some are produced by cell filtration transfer. The quali...
