The present disclosure relates to a diagnostic method and a device performing the same. According to an aspect of the present disclosure, a diagnostic device is a diagnostic device that uses a test kit including a specimen plate having a specimen region in which a specimen is smeared and a patch plate configured to store a contact-type patch, which comes into contact with the specimen to stain the specimen, and the diagnostic device includes a body having a loading region in which the test kit is placed, a moving unit configured to move the patch plate and the specimen plate of the test kit relative to each other so that the specimen placed in the test kit is smeared in the specimen region, and a contact unit configured to move a structure of the test kit such that the contact-type patch comes into contact with the smeared specimen so that the smeared specimen is stained.

A device for generating a dispersion of a first phase in a second phase includes a first inlet opening into a first chamber and being configured to supply a first phase and a second inlet opening into a second chamber and being configured to supply a second phase. A dispersion outlet is configured to collect the dispersion of the first phase in the second phase. A membrane separates the first and second chamber. The membrane includes a first side facing the first chamber and a second side facing the second chamber. Multiple channels extending from the first side to the second side of the membrane are configured to provide a fluidic connection between the first and second chamber. Each channel includes a channel inlet arranged on the first side of the membrane and a channel outlet arranged on the second side of the membrane.
