Description

Technical Field

[0001] This utility model relates to the field of circuit technology, specifically to an automatic feeding control circuit for automatic dyeing equipment. Background Technology

[0002] In existing biological sample analysis techniques, commonly used analytical methods include microscopy, microarray analysis (e.g., protein and nucleic acid microarray analysis), and mass spectrometry. Preparing samples for these and other types of analysis typically involves contacting the biological sample with a series of processing liquids. Some of these processing liquids (e.g., staining reagents and counterstaining reagents) can add color and, conversely, alter 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., deparaffin liquids) can be used to achieve other processing purposes. If multiple processing liquids are used to treat the sample, the application and subsequent removal of each liquid can be crucial for producing a sample suitable for analysis. In some cases, treating samples with multiple processing liquids involves manually applying the liquids to the microscope slides holding the samples. However, this manual sample preparation method tends to be labor-intensive and inaccurate, leading to the development of biological tissue section staining equipment.

[0003] Automated staining technology for biological tissue samples is a crucial and indispensable step in the entire automated staining, drying, and mounting process for biological tissue samples. To ensure that the processed biological tissue samples have an easily observable appearance and maintain consistency and efficiency in the processing, the staining step is an essential aspect that must be strictly controlled during biological tissue sample processing. The purpose of staining is to make different structures within the cellular tissue appear in different colors for easier observation. The classic hematoxylin and eosin staining method is the routine staining method for histological and pathological specimens, abbreviated as HE staining. After staining, the cell nuclei are stained purple-blue by hematoxylin, while most cytoplasm and non-cellular components are stained pink by eosin.

[0004] Existing biological tissue slide 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 slide staining equipment places batches of microscope slides containing biological tissue samples horizontally in slide holders. Although there is some vertical space between each microscope slide, the entire box of slides is processed together during the staining operation. When the spacers are immersed in the shared staining reagent, cross-contamination of the microscope slides within the same box is inevitable. For example, cells from a biological tissue sample slide can leave the sample on one microscope slide and move to another microscope slide in the shared staining reagent. This form of contamination significantly reduces the accuracy of certain types of sample analysis. If it is necessary to separate each microscope slide for individual loading and staining, manual assistance is required, which is cumbersome, time-consuming, labor-intensive, and prone to errors. Therefore, the production efficiency and product quality of biological tissue sample microscope slides are not stable enough to meet user needs. Utility Model Content
