Relay-based de-energizable defibrillation assembly

Abstract

A completely de-energizable defibrillator is provided, allowing the electrical components of the defibrillator to be electrically unbiased while the defibrillator is not in use. The energizing of the defibrillator can be controlled through a power switch interfaced to a relay, with the microcontroller of the AED being able to de-energize the circuitry in case of unintended activation. Additionally, the microcontroller unit of the AED includes features to prevent computational errors due to external influences, electromagnetic interference, radio frequency interference, ionizing radiation, high energy particles, cosmic radiation, and/or solar radiation, or a combination thereof, including one or more pairs of lockstep processors, error detection code, and features that prevent tampering with the microcontroller.
