Improved structure of sample staining module of automatic slide stainer

Abstract

The invention relates to an improved structure of the sample staining module of an automatic slide stainer. The improved structure comprises a shell with a shell cover and is characterized in that theshell cover is hinged to the shell through a connecting shaft; a plurality of liquid storage tanks are arranged in the shell; a heating device is arranged at the bottom of the shell; a cooling fan isarranged below the shell, and a groove with a curved central line is arranged in the bottom of the shell; a control unit is in signal connection with a drive device, a draining valve, the heating device and the cooling fan. The improved structure has the advantages that wind screens are arranged on the three sides of the bottom of the shell, the groove with the curved central line is arranged inthe bottom outer surface of the shell, the opening of the groove is located on the side, without the wind screen, of the bottom of the shell, and accordingly the flowing direction and speed of air flow blown by the cooling fan to the bottom of the shell are improved, the cooling effect of the cooling fan is increased, tissue cell morphology of biological samples after antigen repair is improved, and the accuracy and reliability of pathological examination are increased.

Description

technical field [0001] The invention belongs to the field of medical testing equipment, in particular to the technical field of immunohistochemistry and immunocytochemistry staining, and more specifically to an improved structure of a sample staining module used in an automatic staining machine. Background technique [0002] Immunohistochemistry (IHC) is a new technology developed by combining the theory and technology of immunology with the method of histochemistry, combining the theories and methods of immunology, histology and biochemistry. Utilizing the core of immunology, that is, the principle of specific binding between antigen and antibody, antibodies labeled with enzymes, metal ions, isotopes, etc. are used to track the antigen, and the display agent labeled on the specific antibody bound to the antigen is displayed by a chemical reaction. The color of the dye is observed with the help of a microscope, a fluorescent microscope, and an electron microscope, so as to a...
