Electrode assembly for freezing-type iontophoresis device

摘要

An iontophoresis device capable of stably holding a drug during a storage period and of transdermally administering the drug to an organism at a high transport number during use. The iontophoresis device includes an electric power source. A first electrode assembly may be electrically coupled to the electric power source to store and transdermally administer an ionic drug to an organism via iontophoresis. The first electrode assembly stores the ionic drug at a temperature less than or equal to zero degrees Celsius and administers the ionic drug at a temperature greater than zero degrees Celsius. A second electrode assembly may be electrically coupled to the electric power source as a counter electrode to the first electrode assembly.
