Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical inspection, in particular to a slide staining device for rapid on-site evaluation. Background Art

[0002] Rapid on-site evaluation (ROSE) is an extremely fast cytological judgment technique accompanying diagnostic interventional procedures. It can quickly interpret the puncture specimens obtained by endoscopic ultrasound physicians, evaluate whether the sufficiency of the specimens can meet the diagnostic requirements, provide timely on-site feedback, decide whether to repeat the puncture operation or change the puncture path to obtain more and high-quality specimens, improve the diagnostic rate, reduce unnecessary punctures, and thus reduce the occurrence of operation-related complications.

[0003] Clinically, the Diff-Quik staining method is most commonly used to stain the puncture smears for rapid on-site evaluation. The reagents used are Diff-Quik Solution A, Diff-Quik Solution B, and clear water for cleaning. The main staining steps are to soak the prepared slide in Diff-Quik Solution A for 10 to 30 seconds, then immerse the slide in Diff-Quik Solution B for staining for about 20 to 40 seconds, rinse with clear water, and after drying, it can be sent to an optical microscope for pathological diagnosis.

[0004] Although the existing slide staining components can stain slides in large quantities, they occupy a large space, consume a large amount of staining solution, are not suitable for rapid on-site evaluation during diagnostic interventional procedures, and most of the existing devices use the dipping technique, with a high possibility of sample contamination, affecting the sample quality. At present, most hospitals in China are difficult to achieve automatic slide staining in the rapid on-site evaluation of diagnostic interventional procedures. Summary of the Utility Model

The staining workbench moves towards the inside of the box body along the slide rail, and at the same time, the staining workbench is lifted by a certain angle until it reaches the second working position. The first peristaltic pump pumps out the dye solution from the five-head dropper to soak the glass slide with the dye solution A, and then moves to the third working position and stands still for a period of time. After the staining of the dye solution A is completed, it returns to the second working position. The staining of the dye solution B is completed by the same principle. The third peristaltic pump works to realize the flushing of the glass slide. The air drying unit is started to complete the drying of the glass slide, and the staining workbench returns to the first working position, and the processed glass slides are taken out.
