Automated external defibrillator with a plurality of power sources
First Claim
1. An automated or semi-automated external defibrillator (AED) comprising:
- high voltage circuitry which is operable for generating a defibrillation shock;
processor circuitry which is operable to control the AED;
monitoring circuitry for monitoring the condition of a power source; and
a removable battery cassette having a cover which may be opened and closed, including one or more battery cells, located within the battery cassette and coupled to power the high voltage circuitry, the processor circuitry, and the monitoring circuitry,wherein the high voltage circuitry and the processor circuitry are located external to the battery cassette, andwherein at least one of the battery cells within the battery cassette can be accessed by opening the cover and replaced with another battery cell.

Abstract
An automated or semi-automated external defibrillator (AED) is provided with a plurality of power sources. The AED includes a first power source that powers circuitry creating a defibrillation electrical shock, and a second power source for powering other circuitry. By including a separate power source for the low-power needs of the AED, the high-power source will typically last longer than if the low-power source were omitted. This reduces maintenance costs, particularly where the high-power source is more expensive to replace than the low-power source. Furthermore, one may use the high-power source as a backup to the low-power source so the AED can still operate even if the low-power source fails.
