Abstract
A detachable power supply for supplying power from an external power source to a portable defibrillator for charging a battery of the portable defibrillator and operating the portable defibrillator includes a housing shaped to attach to the portable defibrillator and a latch connected to the housing for mechanically attaching the power supply to the defibrillator so that the power supply and the defibrillator form a portable, integral unit. The power supply also includes an electrical connector connected to the housing to supply power from the power supply to the defibrillator, the connector is located so that it engages a mating electrical connector on the defibrillator as the latch is engaged to connect the power supply to the defibrillator, an external power connection for bringing external power into the power supply, and a power module installed within the housing, the power module having a power circuit that converts power from the external power source to a form useable by the defibrillator, the output of the power module being connected to the electrical connector to deliver power to the defibrillator. Typically, the power module is alternately operable in both a controlled current mode and a controlled voltage mode.
