Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smear staining and fixing devices, in particular to a blood cell smear staining and fixing device. Background Technique
[0002] As is well known, the microscopic examination of blood smears is a basic method for blood cytology examination and is widely used. It is especially valuable for the diagnosis of various blood diseases. The physical action of staining utilizes capillary action, penetration, absorption, and adsorption to firmly enter the tissue cells with the pigment particles of the dye and make them show color; the chemical action of staining is that the dye penetrating into the tissue cells reacts with its corresponding substances to produce colored compounds for easy observation of cells.
[0003] Among them, blood cell smear staining usually uses the Wright-Giemsa staining method. First, drop blood on a glass slide with a dropper, hold the glass slide by hand, and use another glass slide to scrape the blood at an angle of 30 - 45 degrees with the glass slide with the dropped blood, so that the blood is spread on the glass slide for subsequent staining. However, in this operation, since the tester wears gloves, when the two glass slides are toggled with each other, the glass slide with the dropped blood is squeezed, and it is easy to drop the glass slide with the dropped blood. Therefore, we have designed a blood cell smear staining and fixing device. Content of the Utility Model
