AED and battery pack with anticipatory battery disengagement detection

摘要

An AED includes a housing. Electronic circuitry is disposed in the housing for delivery of an electric shock to a stricken patient. A removable battery pack is selectively, operably, communicatively coupled to the electronic circuitry. The battery pack has an anticipatory detector for generating an anticipatory signal to the electronic circuitry. The signal indicates to the electronic circuitry that the disengagement of the battery pack from the AED is imminent. The present invention further includes a method for ensuring that the high voltage storage circuits of the AED are safely discharged prior to disengaging the battery pack from the AED.
