ABSTRACT:
An iontophoresis-based medical device includes a positive electrode section, a negative electrode section, a power source supplying an electric current to the positive electrode section and negative electrode section and a controller controlling the current value and conduction time of the electric current, wherein a writing brush is electrically connected to the positive electrode section, and a sponge is electrically connected to the negative electrode section, and the writing brush is formed of a large number of long soft hairs and a large number of short soft hairs such that the writing brush has a columnar shape at a base portion thereof and is gradually tapered toward a tip portion thereof from a middle portion thereof and the tip portion is made extremely fine to form an acute apex thus allowing the apex to touch an affected part in a pinpoint manner.
