Automatic cell block preparation machine and method

Abstract

The invention relates to an automatic cell block preparation machine and method. The automatic cell block preparation machine comprises a body, as well as a centrifugal assembly, a temperature controlassembly, a mechanical arm, a liquid path assembly, a table type host and the like which are all arranged on the body. Through the automatic cell block preparation machine and a cell block preparation tube with a matrix, cells in a cytological specimen are separated and enriched on a plane after centrifugation and are automatically prepared into cell blocks, so that automation, standardization and high quality of cell block preparation are realized.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic cell block preparation machine and method. Background technique [0002] Cytopathology diagnoses many diseases and assesses health by analyzing cells or small clusters of cells. [0003] The most commonly used technique in cytopathology is the cytosmear. Cell smear is to smear cells or small cell groups on glass slides, stain with diagnostic reagents, and observe cell morphology under a microscope to diagnose various diseases or evaluate health status. The cell smear method has obvious limitations, mainly in: the cell smear cannot be replicated, once the cell smear is stained with a diagnostic reagent, it is difficult to perform additional staining and detection at the same time; it is difficult to perform immunohistochemistry and molecular pathology Blood, protein deposits, mucus interference, and cell accumulation make the shape and structure of cells u...

Problems solved by technology

However, these existing methods have different defects, the most obvious of which are: they all manually prepare cell blocks one by one, which is time-consuming and labor-intensive; the preparation of cell blocks lacks standardization, normalization and quality control; When the number of clumps is small, the cell block is prepared; the position of the target cells (disease cells) in the cell wax block is scattered and uncertain, and it is difficult to cut the diseased cells when slicing, or the distribution of cells on the slice is small and the density is low; wax Irregular block size, shape, etc.
