[0002] Microscopic examination of blood smears is a basic method for blood cytology examination and is widely used, especially for the diagnosis of various blood diseases. However, poor preparation and staining of blood smears often make cell identification difficult and even lead to erroneous conclusions. For example, if the blood film is too thick, the cells overlap and shrink, and if the blood film is too thin, the white blood cells are mostly concentrated at the edge. Well-stained blood smears are one of the main basic techniques for hematological examinations. Liquid smearers are the most commonly used blood smearers. Blood smears in the prior art generally include glass slides and blood slides. At present, cotton swabs are usually used to perform smear tests on patients in clinical practice. Samples are dipped from test tubes and then smeared on glass slides for testing. This operation is very troublesome, time-consuming and labor-intensive, and the smearing is uneven, which affects the diagnosis results and adds a certain degree of difficulty to medical staff.
