Defibrillator with improved utilization of the accumulator energy

摘要: The invention relates to a defibrillator having capacitor (4) which is chargeable via DC-DC converter (3) by an accumulator (i.e., rechargeable battery) (1). Between the (1) and there situated control device (2) which, as internal resistance (Ri) of increases, draws lower current from latter, so that output voltage kept approximately constant. Before automatically deactivated energy already stored in internally destroyed, controller interrupts charging when residual remaining less than amount required charge desired energy.
