Description

Technical Field

[0001] The invention relates to the technical field of biological tissue sample slice staining, and in particular to an automatic staining mechanism of biological tissue sample slice staining equipment. Background Art

[0002] In the existing biological sample analysis technology, the analysis methods commonly used include microscopic analysis, microarray analysis (e.g., protein and nucleic acid microarray analysis) and mass spectrometry. Preparing samples for these and other types of analysis usually includes: contacting the biological sample with a series of processing liquids. Some of these processing liquids (e.g., staining reagents and counterstaining reagents) can add colors and, in contrast or on the contrary, change the visual characteristics of invisible or difficult-to-see sample components (e.g., at least some types of cells and intracellular structures). Other processing liquids (e.g., deparaffinized liquids) can be used to achieve other processing purposes. If a variety of processing liquids are used to process the sample, the application and subsequent removal of various processing liquids can be very important for producing samples suitable for analysis. In some cases, processing samples with a variety of processing liquids includes: manually applying the processing liquids to microscope slides that carry the samples respectively. However, this method of manually processing samples tends to be labor-intensive and imprecise, so biological tissue sample section staining equipment has emerged.

[0003] The automatic staining and processing technology of biological tissue sample sections is an important step in the entire process of automated staining, drying and sealing of biological tissue samples. It is also an indispensable step. In order to make the processed biological tissue samples have an appearance that is easy to observe and to maintain the consistency and efficiency of the processing process, the staining step is an object that must be strictly controlled during the processing of biological tissue samples. The purpose of staining is to make different structures in cell tissues present different colors for easy observation. The classic hematoxylin and eosin (eosin) staining method is a routine staining for histological specimens and pathological section specimens, referred to as HE staining. After staining, the cell nucleus is stained purple-blue by hematoxylin, and most cytoplasm and non-cellular components are stained pink by eosin.

[0004] Existing biological tissue sample section staining equipment can replace manual staining. These machines automatically process samples by immersing racks carrying batches of microscope slides in an open bath of processing liquid. However, the existing biological tissue sample section staining equipment places batches of microscope slides containing biological tissue sample sections horizontally in a slide carrier box. Although there is a certain upper and lower space interval between each microscope slide, a whole box of microscope slides is processed together during the immersion staining operation. When the intervals are immersed in a common staining reagent, it is inevitable that there is a risk of cross-contamination between microscope slides in the same box. For example, cells of biological tissue sample sections can leave the sample on one microscope slide and move to another microscope slide in the common staining reagent. This form of contamination greatly reduces the accuracy of certain types of sample analysis. Moreover, after a whole box of horizontally placed microscope slides are immersed in a common staining reagent, the osmotic pressure of the staining reagent applied to the upper microscope slide is lower than that applied to the lower microscope slide, inevitably leading to the problem of uneven staining of the upper and lower microscope slides, resulting in poor product quality consistency of the final stained biological tissue sample section microscope slides, and bringing a very bad user experience.
