Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a double-layer centrifugal drip dyeing machine. Background Art

[0002] The centrifugal drip dyeing machine is a device used for dyeing glass slide samples. A tray for placing glass slides is provided inside the dyeing machine. The dyeing liquid is automatically injected into the dyeing chamber and mixed to perform a dyeing reaction on the glass slides in the dyeing chamber. After the reaction is completed, the centrifugal force generated by the rotation of the tray causes the dyeing liquid to be discharged. The operation is cyclically repeated: adding, mixing, reacting, and discharging the dyeing liquid, thereby completing different dyeing reaction operations with different dyeing liquids. Finally, the dyeing liquid is discharged to dry the glass slide, and then hot air drying is performed to make the glass slide completely dry for subsequent microscope reading, thereby replacing the heavy work of manual glass slide dyeing.

[0003] The centrifugal staining machine drips dye into a tray through a dye dripping nozzle. A plurality of dye chambers for placing glass slides are circumferentially arranged in the tray. The dye dripping nozzle dyes the glass slide by dripping dye into the dye chamber. Since the current centrifugal staining machine has a small number of dye dripping nozzles, there is a problem of low dyeing efficiency when dyeing multiple glass slides. For example, the invention patent with publication number CN107957364A discloses an automatic dyeing device, which is provided with two dye dripping parts, which are respectively used for Gram staining and acid-fast staining. The dye is dripped onto the glass slide through the dripping head arranged on the dye dripping part. Since only one glass slide can be dripped at a time, it is not only difficult to improve the dyeing efficiency, but also easy to increase the batch difference of the same batch of specimens.
