Abstract:
A cardiac defibrillator for discharging an electrical charge into a patient, comprising:a mechanical energy storage device adapted to be located external to the patient; a generator coupled to the mechanical energy storage device and configured to convert mechanical energy stored in the mechanical energy storage device into electrical energy wherein the electrical energy converted by the generator from the mechanical energy stored in the mechanical energy storage device provides the electrical charge for discharging into the patient; an electrical charge storage device adapted to store the electrical energy; a charging circuit coupled to the generator and configured to transfer the electrical energy to the electrical charge storage device; a patient interface adapted to be coupled to the charging circuit and the patient and configured to provide an electrical path for discharging the electrical charge; an input device configured to generate a discharge signal; a control unit coupled to the electrical charge storage device and the input device and configured to control the discharge of the electrical charge into the patient in response to the discharge signal; wherein the electrical energy converted by the generator from the mechanical energy is stored in the electrical charge storage device so that the electrical charge is dischargeable into the patient through the patient interface upon operation of the input device.
