Description

Technical Field

[0001] The utility model relates to the technical field of tissue dehydrators, in particular to a full-automatic tissue dehydrator. Background Art

[0002] With the advancement of medical science, diagnostic methods are becoming increasingly diverse. However, to date, even in the world's most technologically advanced countries, disease diagnosis is still primarily based on pathology. Pathology techniques are an integral part of pathological diagnosis, and the quality of slide preparation significantly impacts the pathologist's ability to accurately diagnose. Dehydration is the first step in pathology slide preparation. Tissue removed from the human body must first undergo dehydration and other processing before the pathologist can clearly identify the tissue's properties under a microscope.

[0003] The underlying principle of the dehydrator is to extract the water from the cells and intercellular spaces of biological tissues by immersing them in different reagents and reagents with different concentration gradients to achieve the purpose of dehydration. Finally, the dehydrated tissues are immersed in paraffin and taken out together.

[0004] Traditional mechanical dehydrators place different reagents in separate containers. A tissue sample basket is mechanically moved to the top of the target reagent container. The container lid is opened, and the sample basket is lowered into the liquid for immersion, while a certain temperature is applied. After the timer expires, the sample basket rises and moves to the top of the next target reagent container. This immersion process is repeated until all immersion steps are complete, and the reagents remain within the container throughout the entire process. The mechanical lifting mechanism of this dehydrator is prone to failure. If the lifting mechanism is not in place, the cylinder will become stuck, leaving the container open and easily causing the biological tissue specimen to air-dry. Utility Model Content

The gas purification device 9 is used to purify the gas in the pipeline and is suitable for discharging the gas in the pipeline into the gas purification device 9 through the exhaust pipeline after the reagent in the reaction container 2 is discharged into the reagent module 3. Specifically, the pipeline connecting the manifold and the reaction container 2 is connected to the gas purification device 9 through the exhaust pipeline, and a valve is set on the exhaust pipeline to control the on-off. When the reagent circulates in the reagent pipeline, the valve on the exhaust pipeline is closed.
