Abstract
A cardiac defibrillator for discharging an electrical charge into a patient includes a device for storing mechanical energy, a generator, a capacitor, a charging circuit, a patient interface, an input device, and a control unit. The generator converts mechanical energy stored in the mechanical energy storage device into electrical energy. The charging circuit transfers the electrical energy to the capacitor, wherein the electrical energy is stored in the capacitor. The patient interface provides an electrical path for discharging the electrical energy stored in the capacitor into the patient. The input device is configured to generate a discharge signal. The control unit controls the discharge of the electrical energy into the patient in response to the discharge signal. The mechanical-to-electrical energy converter assembly can also be used to power other medical devices that conventionally run on batteries or AC power line sources.
