Description

TECHNICAL FIELD

[0001] The utility model relates to medical examination equipment technical field, concretely is multi -specification dye liquor conversion head. BACKGROUND

[0002] Tissue section staining is an important step in pathology, biology and medical research, which involves staining tissue samples (usually tissue blocks cut into thin sections after fixation, dehydration, transparency and embedding steps) to facilitate observation and analysis under a microscope. This process aims to enhance the visibility and contrast of structures in the tissue, such as cells, organelles, fibers, blood vessels, inflammatory cells, etc., so that pathologists can more accurately identify and diagnose diseases. Staining is mainly based on chemical and physical interactions. Staining agents (such as dyes or colored compounds) bind to specific components in the tissue (such as proteins, nucleic acids, lipids, etc.), forming visible color changes. These color changes reflect the chemical properties and structural characteristics of the tissue components. Currently, when performing staining operations, manual staining and automatic staining machines are usually used for staining operations.

[0003] The disadvantages of manual staining are: 1. Laboratory manual staining kit, generally packaged as four bottles with bottle mouth film sealing, technicians usually use the mode of tearing the sealing film and directly pouring, which is not easy to control the reagent amount and may waste reagents; 2. Some technicians use a pipette to suck reagents, which is tedious and inconvenient to operate; 3. When the sample amount is large, the manual staining efficiency is low, which affects the experimental progress.

[0004] The disadvantages of automatic staining machine are: 1. Sample amount: although it can process a large number of samples more efficiently, for small, complex or special samples, more delicate manual staining or special treatment may be required; 2. Cost: the operation and maintenance cost of automatic staining machine is high. Such machines are usually expensive, in addition, in order to ensure the accuracy and reliability of the staining results, the machine needs to be regularly tested and calibrated; 3. Efficiency: when the sample amount is small, using automatic staining machine will waste time and reagents, therefore, there is room for improvement. UTILITY MODEL CONTENT
