First Claim
Patent Images
1. An external defibrillator, comprising:
- a battery;
defibrillation circuitry, the defibrillation circuitry powered by the battery and includinga micro-controller programmed to conduct a self-test and programmed to perform a rescue by executing a program stored thereon, the self-test including at least a portion of the defibrillation circuitry, the self-test including an internal shock at less than full-voltage; and
an active status indicator comprising a first light source that illuminates, the first light source operated by the programming running on the micro-controller, wherein when the self-test has determined that the defibrillator operational status is normal, the first light source blinks frequently to indicate that the defibrillator is ready for use.

Abstract
An AED includes defibrillation circuitry housed within an enclosure, a first processor programmed to periodically test the operability of the defibrillation circuitry and a second processor in communication with the first processor. The AED further includes a visual indicator, such as a red/green LED, positioned at the exterior of the enclosure that is operatively connected to the second processor. The second processor is programmed to control the visual indicator in response to the periodic test results provided to it by the first processor.

7. An external defibrillator, comprising:
-
a battery; defibrillation circuitry, the defibrillation circuitry powered by the battery and including a micro-controller programmed to conduct a self-test and programmed to perform a rescue by executing a program stored thereon, the self-test including at least some portion of the defibrillation circuitry, the self-test being conducted autonomously and including an internal shock at less than full-voltage; and an active status indicator comprising a first light source that illuminates, the first light source operated by the programming running on the micro-controller and mounted on a surface of the external defibrillator, the surface visible from an exterior of the external defibrillator, wherein when the self-test has determined that the defibrillator requires maintenance, the first light source illuminates to indicate that the defibrillator requires maintenance. - View Dependent Claims (8, 9)
