Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a heating block device for a tissue slide. Background Art

[0002] Staining slides for microscopic observation is the most widely used and basic technology in pathological diagnosis. Before staining, the slides need to be baked so that the tissue fits tightly against the slide and does not fall off. This is an important step to ensure the smooth completion of the subsequent staining process. After the paraffin-embedded tissue is sliced, it is mounted on the surface of the slide. To avoid tissue damage or position drift caused by direct high-temperature baking, it is necessary to wait until the moisture between the slide and the tissue is dried, and then bake it for a certain time and temperature to melt the paraffin wrapped around the tissue, and the tissue fits tightly against the slide for subsequent related staining operations.

[0003] Therefore, it is necessary to design a heating device specifically for tissue slides, so that the tissue slides can be placed on the heating device for heating and the heating temperature can be controlled in real time. Utility Model Content
