20090171313 | IONTOPHORESIS DEVICE HAVING AN ACTIVE ELECTRODE UNIT - An iontophoresis device transdermally administers an active agent, such as a drug ion, to a biological interface of an organism. The iontophoresis device includes a first electrode assembly having a first electrode member, which is electrically coupled to a terminal, of a main electric power source, having a first polarity that is the same polarity as that of a drug ion. The iontophoresis device includes a drug solution reservoir arranged in an electric field generated by the first electrode member and holding a drug, a counter electrode assembly electrically coupled to another terminal (of the main electric power source) having a second polarity that is opposite to the first polarity, and a vibrating portion having an ultrasonic oscillator for oscillating an ultrasonic wave and an ultrasonic vibrator vibrating due to the ultrasonic wave supplied from the ultrasonic oscillator. The ultrasonic vibrator is provided in the vicinity of the active electrode assembly. | 07-02-2009 |
