Tested functions include the presence and interconnection of defibrillator electrodes, battery charge state and the operability of the high voltage circuit. Visual and audible indicators are actuated to alert an operator if faults are identified. A record of each self-test is stored in memory, and can be subsequently retrieved through a communications port.
What is claimed is: 1. A one button method of applying a defibrillation shock to a patient using an automated external defibrillator (AED) having a case including an electrode compartment, a pair of electrodes stored within the electrode compartment, an openable lid covering the electrode compartment, a high voltage circuit, and an operator-actuated rescue switch, the method including the steps of:opening the lid covering the electrode compartment to expose the electrodes therein wherein the electrodes are electrically connected to the AED prior to the opening of the lid and wherein the step of opening the lid causes the AED to be powered ON; retrieving the electrodes stored in the compartment; applying the electrodes to the patient; pausing while the high voltage circuit charges; and actuating the operator-actuating rescue switch a single time to apply a defibrillation shock to the patient via the electrodes. 2. The method as in claim 1 further including the step of opening a package containing the electrodes prior to the step of applying the electrodes to the patient.
REFERENCE TO RELATED APPLICATION This application is a Continuation of application Ser. No. 08/512,441 filed Aug. 8, 1995, now U.S. Pat. No. 5,645,571 which is a Continuation-In-Part of commonly assigned U.S. application Ser. No. 08/509,990 filed Aug. 1, 1995 which was abandoned on Nov. 11, 1997 and was entitled `Automated External Defibrillator Operator Interface`.
SUMMARY OF THE INVENTION The present invention is an improved automated external defibrillator (AED). One embodiment of the defibrillator includes a digital control system with self-test means for periodically and automatically performing self-tests of one or more defibrillator components. If a malfunctioning component is identified, the self-test means actuates an audible alarm or other maintenance indicator to alert an operator. Tested functions include the presence and interconnection of defibrillator electrodes, battery charge state, the functionality of the high voltage circuit and the functionality of the digital control system. Some functions are self-tested daily, while others are self-tested weekly.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an automated external defibrillator (AED) in accordance with the present invention, with the electrode compartment lid closed.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A semi-automatic, automated external defibrillator (AED) 10 in accordance with the present invention is illustrated generally in FIGS. 1-3. As shown, defibrillator 10 includes a plastic case 12 with a carrying handle 14 on the top portion. A battery compartment (not visible) in the bottom portion of the defibrillator 10 is enclosed by a semi-transparent battery cover 16. An illuminatable rescue switch 18, visual maintenance indicator 20, data communication port 22 and charging port 24 are located on the outside of case 12 for easy access by an operator.
FIG. 6 is a block diagram of the electrical system 70 of defibrillator 10. The overall operation of defibrillator 10 is controlled by a digital microprocessor-based control system 72 which includes a processor 74 interfaced to program memory 76, data memory 77, event memory 78 and real time clock 79. The operating program executed by processor 74 is stored in program memory 76. Data memory 77 is used by processor 74 as a scratch pad memory during the execution of the operating program. Electrical power is provided by a rechargeable twelve volt lead-acid cartridge battery 80 and a nine volt battery 82 which are removably positioned within the battery compartment and connected to power generation circuit 84. During normal operation, power generation circuit 84 generates regulated .+-.5 V, 3.3 V and 12 V (actually about 13.3 V) supplies with the power provided by the twelve volt battery 80. Nine volt battery 82 functions as a back-up battery to power components of electrical system 70 during the execution of self-tests and to activate maintenance indicators and alarms (as described below) if the twelve volt battery 80 is low on charge. Although not separately shown in FIG. 6, power generation circuit 84 includes voltage level sensing circuits which are coupled to processor 74. The voltage level sensing circuits provide low battery level signals to processor 74 whenever the voltage levels of batteries 80 or 82 are less than predetermined values such as 12.3 V and 8 V, respectively.
The .+-.5 V supply is used to power the control system 72 and most other electrical components of electrical system 70. The 3.3 V supply is coupled to nonvolatile event memory 78 in which, as is described in greater detail below, data representative of the patient's cardiac rhythm and the rescue mode operation of defibrillator 10 are stored. A high voltage generation circuit 86 is connected to receive the 12 V supply. Charging port 24 is coupled to power generation circuit 84, enabling twelve volt battery 80 to be connected to a twelve volt vehicle battery (not shown) or a 120 VAC charger (also not shown) and recharged while mounted within the defibrillator 12. Alternatively battery 80 can be removed from defibrillator 10 and charged in a stand-alone charger (not shown). Defibrillator 10 cannot be operated when a charger is connected to charge port 24. Circuitry (not separately shown) within power generation circuit 84 senses the interconnection of port 24 to a charger, and provides a charger connected signal to processor 74 when a connected charger is sensed.
