Different dyes have selective affinity for different components within the cell and can highlight the structure and morphology of these components. Cell smear staining not only helps to identify different types of cells, but also reveals pathological changes in cells. It is an important tool in clinical pathological diagnosis and biomedical research.

When in use, first pull out the sealing plug plate 8 from the vertical sealing slot, and control the reciprocating push drive component 3 to make one end of the flip-type clamping and positioning component 7 pass through the give way through-hole groove and move to the outside of the closed operation box 1, so that the flip-type clamping and positioning component 7 can clamp and fix the glass slide. The position of the glass slide is adjusted by the reciprocating push drive component 3, and the glass slide is moved to the inside of the closed operation box 1, and the sealing plug plate 8 is inserted into the vertical sealing slot to achieve the closure of the sealed operation box. While fixing the glass slide, the disinfection lamp 9 is always in the on state, and the flip-type clamping and positioning component 7 is controlled to make the glass slide flip over to achieve thorough disinfection of the glass slide. When the glass slide is controlled to move horizontally to the bottom of the drip-in scraping component 15, the control The lifting drive component 13 makes the dripping and scraping component 15 located at a smaller position above the glass slide, and the cell tissue is dripped onto the glass slide through the dripping head 11 and the dripping and scraping component 15, and the cell tissue is evenly scraped on the glass slide.
