Transdermal drug delivery and permeation promotion device and method

The invention discloses a transdermal drug delivery and infiltration promotion device which comprises a device body, and a control module, a plasma and electroporation module, an iontophoresis module and a power module are arranged in the device body; wherein the control module is used for converting a first low-voltage direct-current signal provided by the power supply module into a second low-voltage direct-current signal so as to supply the second low-voltage direct-current signal to the plasma and electroporation module; the plasma and electroporation module is used for converting a second low-voltage direct-current signal provided by the control module into a symmetric oscillation high-voltage pulse signal and guiding the symmetric oscillation high-voltage pulse signal into the skin surface through a high-voltage electrode; the ion introduction module is used for converting a first low-voltage direct-current signal provided by the power supply module into a rectangular pulse signal and introducing the re
