AUTOMATIC PHASE REVERSING DEVICE FOR AED

摘要

PURPOSE: An automatic phase reversing device for a defibrillator is provided to diversify electric impulse wave only by a manual switching element. CONSTITUTION: An automatic phase reversing device for a defibrillator comprises a high voltage capacitor(106), an integrator, and a phase controller(138). The high voltage capacitor stores power provided from a power supply unit and generates electric impulse wave according to a breakdown control signal of a controller. The integrator integrates branched current produces the voltage of the power source applied to a patient. The phase controller turns reversely the phase of electric impulse wave and applies electric impulse wave of the reverse direction to the patient.
