Abstract:
A defibrillator having a capacitor (4) which is chargeable via a DC-DC converter (3) by an accumulator (1), characterized in that a control device (2) is situated between the accumulator (1) and the capacitor (4) which control device (2)as the internal resistance (Ri) of the accumulator (1) increases, draws a lower current from the latter, so that the output voltage of the accumulator (1) is kept approximately constant, andinterrupts the charging of the capacitor (4) before the defibrillator is automatically deactivated and internally destroys the energy already stored in the capacitor (4) when the residual energy remaining in the accumulator (1) is not sufficient to charge the capacitor (4) to the desired energy, andin that, moreover, the energy already stored in the capacitor (4) is indicated.
