Exemplarily, since the concentration of the staining liquid drug is high and it is easy to crystallize and corrode, a stainless steel corrosion-resistant pipeline with an inner diameter of 2mm can be used for drug delivery.

[0051] In summary, the microbial staining automatic device in the embodiment can set multiple staining modes to simulate manual staining, accurately control the staining time and the amount of drug sucking and dropping, and ensure that the drug can be taken out at will, so that it can be stored in a safe when not in use, reduce the detection cost, and ensure the storage environment of the drug.
