Description

Technical Field

[0001] This application belongs to the field of detection technology, and specifically relates to an apparatus for preparing samples containing solid substances such as feces. Background Technology

[0002] In existing technologies, viscous samples such as feces typically require dilution during preparation. However, the amount of the target analyte of interest is usually small, and sufficient enrichment is needed before microscopic imaging. Therefore, in situations requiring both dilution and enrichment, such as the examination of parasite eggs in feces, thorough dilution is first necessary to separate the eggs from fecal impurities. After egg separation, the eggs need to be enriched and excess water removed. In a preparation process, the diluted portion becomes denser in the next step, requiring additional water to continue dilution. Existing technologies cannot perform this continuous operation. Summary of the Invention

[0003] In the preparation of viscous samples such as feces, the portion diluted in one step becomes increasingly viscous as the sample moves to the next stage, requiring the addition of water to complete the dilution process. This application addresses this by adding a liquid-adding section to the lid of the sample preparation box. This section allows for the addition of preparation solution at any time during the preparation process. The preparation solution can be a diluent, staining solution, or a diluted staining solution.
