Magnetic field therapy unit for treating of patients, e.g. for improvement of blood circulation, has optically coupled impulse generator and impulse processing unit, with separate control loops for positive and negative pulses

摘要

Magnetic field therapy device has a control device and an application coil that generates alternating current square wave impulses. The control unit comprises an impulse generating unit and an impulse processing unit, with the coupling between the two units controlled by an opto-coupler. The impulse processing unit has control circuits each with a switch for the positive and negative impulses.
