[0001] This utility model relates to the technical field of staining devices, specifically to a portable staining device for preparing pathological sections. Background Technology

[0002] Pathological specimens on slides include smears of tissues, organs, blood, bone marrow, and various fluid tissues. The main function of a pathological staining device is to stain pathological slides, causing different components in cells and tissues to display different colors. This allows pathologists to clearly observe the morphology and structure of these components under a microscope, distinguish between diseased and normal tissues, and accurately determine the type and extent of lesions. This provides crucial information for disease diagnosis and prognosis assessment, and also aids researchers in studying pathological mechanisms.

[0003] The existing technology still has the following areas for improvement: the structure of the existing portable staining rack is not stable enough, which can easily cause the slides to fall off or shift during the staining process, thus affecting the staining effect; the clips or slots for fixing the slides cannot firmly hold the slides; due to the insufficient stability of the staining rack, the slides may not be able to maintain a horizontal or uniform position in the staining solution, resulting in uneven staining; the staining solution may not be able to fully penetrate into the tissue sections, thus affecting the staining quality; and the existing portable staining racks are heavy and bulky, making them inconvenient to carry and move.
