Embodiment 1

[0010] a Separate the cells, put the liquid-based cell extract solution into the liquid-based cell extract solution container equipped with the filter cartridge and the cell preservation solution, and then put the liquid-based cell extract solution container on the centrifuge disk of the tableting device, and then put Under the control of the cell crusher, the cell crusher loaded on the production equipment automatically runs downwards and enters the upper part of the filter cartridge in the pathological cell extraction solution container, and the cell preservation solution is pumped into the cell crusher, and then discharged into the pathological cell extraction solution. inside the container. This is repeated many times, so that the cells wrapped in mucus are broken up and separated in the narrow needle tube of the cell breaker;

[0011] b. Filtration and sedimentation, under program control, the centrifugal motor is automatically started, and under the action of centrifugal...

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 production method for automatically producing liquid-based cell glass slides on a pathological glass slide manufacturing device used in pathological examinations. Background technique [0002] In the prior art, there are many methods for liquid-based cell preparation. Such as membrane transfer method, centrifugal smear method, natural sedimentation method and other methods. In order to realize these methods, various equipments are used together. For example, the cell liquid is centrifuged and sedimented by a centrifuge, and then placed on a tablet machine for cell dispersing and separation, and then the cell liquid is manually taken out for centrifugal sedimentation. multiple manual operations. After centrifugation on a centrifuge, the cells are dispersed and separated by manual operation, and then pelleted by natural sedimentation. Some are prepared by cell filter transfer. The quality of these production methods is grea...
