IONTOPHORESIS APPARATUS Russian patent published in 2006 - IPC A61N1/30 

FIELD: medicine.

SUBSTANCE: apparatus can be used for transdermal introduction of ion preparations by means of iontophoresis. Apparatus has electrode for iontophoresis (active electrode) and grounding electrode (non-active electrode) both connected with power supply. Electrodes are made of membranes. First membrane disposed on front side of electrode holds electrolytic solution. First ion-exchange membrane disposed on first membrane is selective to ions having charge being opposite in polarity to charges of ions of preparation. Second membrane is disposed onto first ion-exchange membrane and is intended for holding ion preparation. Second ion-exchange membrane is selective to like ions as ions from ion preparations. There is at least one ion-exchange membrane, which is selective to ions with opposite of ion preparation; the membrane is located at grounding electrode. Apparatus allows introducing ion preparation without stoppage for long periods of time with high transfer trial to provide less skin irritation.

EFFECT: improved convenience.
