[0002] Medical smears are a commonly used clinical examination method, primarily used to detect pathogens or cell morphological changes in blood and tissue. Smear examinations are simple to perform and cover a wide range of conditions, including blood smears, sputum smears, and cervical cytology smears. Microscopic observation of the morphology, number, distribution, and positive rate of cells in a smear allows for early detection of cellular abnormalities and screening for various diseases, with high diagnostic value. The smear device is a tool used to evenly apply blood to a glass slide.
