  • APPARATUS AND METHOD FOR MAINTAINING A DEFIBRILLATOR BATTERY CHARGE AND OPTIONALLY COMMUNICATING
    Publication number: 20090264948
    Abstract: Defibrillator assemblies and methods to wirelessly transfer energy from an external source to a battery or other rechargeable power source within the defibrillator assembly. The transfer of energy may be through a non-contact interface on a defibrillator cradle or a docking station that mounts the defibrillator. The rate of energy transfer may be equal to the energy drain caused by self-discharge and automated self-testing. Accordingly, since the rate of energy transfer is lower than that required to run the defibrillator system continuously, several wireless methods of energy transfer may be used. In addition, the defibrillator assembly may communicate diagnostic and non-diagnostic data to the external source.

  • Portable defibrillator with bypass line power emergency charging of capacitor
    Publication number: 20040267322
    Abstract: The present invention provides a portable defibrillator having a capacitor adapted to receive an electrical charge to deliver a defibrillation charge. Power terminals are provided to receive line power. A charging circuit is provided to charge the capacitor from line power after the power terminals receive line power. Therefore, the defibrillator is capable of receiving line power, such as standard 120 VAC, to charge the defibrillator's capacitor. By charging the capacitor directly through line power, the capacitor is charged in much less time than searching for and replacing a defibrillator battery.
