Description

TECHNICAL FIELD

[0001] The utility model relates to a circuit technical field, concretely relates to a kind of automatic dyeing control circuit for automatic dyeing equipment. BACKGROUND

[0002] In existing biological sample analysis techniques, commonly used analysis methods include microscopy analysis, microarray analysis (e.g., protein and nucleic acid microarray analysis) and mass spectrometry analysis. Preparing samples for these and other types of analysis typically involves contacting a biological sample with a series of processing liquids. Some of these processing liquids (e.g., staining reagents and counterstaining reagents) can add color and, in contrast or opposition, change the visual properties of invisible or difficult-to-see sample components (e.g., at least some types of cells and intracellular structures). Other processing liquids (e.g., deparaffinization liquids) can be used to achieve other processing purposes. If multiple processing liquids are used to process a sample, the application and subsequent removal of the various processing liquids can be important to producing a sample that is suitable for analysis. In some cases, processing a sample with multiple processing liquids involves manually applying the processing liquids to a microscope slide that separately carries the sample. But this manual method of processing a sample tends to be labor intensive and imprecise, and thus biological tissue sample section staining apparatuses have been developed.

[0003] Automatic staining processing technology of biological tissue sample section is an important step and an indispensable step in the whole automatic staining and drying and sealing process of biological tissue sample, and the staining step is an object that must be strictly controlled in the processing of biological tissue sample in order to make the processed biological tissue sample have a good appearance for observation and keep consistency and high efficiency of the processing. The purpose of staining is to make different structures in cell tissue present different colors for observation. The classic hematoxylin and eosin staining method is a conventional staining method for histological specimens and pathological section specimens, which is referred to as HE staining. After staining, the cell nucleus is dyed purple blue by hematoxylin, and most of the cytoplasm and non-cell components are dyed 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, existing biological tissue sample section staining equipment places batches of microscope slides carrying biological tissue sample sections horizontally in slide carrying cassettes, and although there is a certain vertical spacing between each microscope slide, when immersed in staining operations, the entire batch of microscope slides is processed together, and when immersed in a common staining reagent, inevitably leads to the risk of cross-contamination of microscope slides in the same cassette. For example, cells of a biological tissue sample section 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, since the staining reagent is consumed during continuous use, it is necessary to add various staining reagents from time to time to ensure the normal operation of the staining operation, but the existing staining equipment generally manually adds the staining reagent after manually observing the amount of reagent in the temporary storage assembly or the staining tank, which is troublesome, time-consuming and labor-intensive, and is prone to errors and forgetting, so that the production efficiency and product quality of the biological tissue sample section microscope slide product are not stable enough, and it is difficult to meet the user's use requirements.
