| titleOfInvention | Device for iontophoresis |
| abstract | A device for iontophoresis that reduces irritation at the beginning of energization and efficiently supplies an amount of current required for drug administration in a predetermined length of time, is provided. With the device for iontophoresis, the oscillation frequency and duty cycle of a transistor 15 are adjusted at the beginning of energization, thereby controlling a back electromotive force developed across a coil 13 to gradually increase the output voltage. The microcomputer 12 controls the transistor 15 so as to receive signals from an output voltage detecting circuit that is formed of resistors 23 and 24 and an output current detecting circuit that is formed of resistors 25 and 26 and a capacitor 27, preventing an increasing of the output voltage when the detected output current reaches a limiting value, and preventing an increasing of the output current when the detected output voltage reaches a limiting value. <IMAGE> |
