Abstract

The connector between the patient electrode pads and the base unit of an automatic external defibrillator (AED) system can be formed by capturing a printed circuit board (PCB) within a connector housing. The PCB can have conductive metal traces that serve as the contact points between the wires from the patient electrodes and the electronics within the AED base unit. The PCB in combination with the conductive metal traces can be shaped similar to a conventional two-prong or two-blade connector. Employing such a PCB-based connector may result in AED pads which are less complex and less costly to manufacture. The PCB can also support a configuration circuit that is positioned between the conductive metal traces and that allows the AED to read and store information about the attached pads. For example, the AED can use this data storage feature to check the expiration date of the pads.

Claims

1. A method for tracking and monitoring information about an electrode coupled to a defibrillator comprising:

coupling the electrode to the defibrillator with a connector system, the connector system comprising a housing and two or more contacts, each contact comprising a conductive planar trace positioned on a printed circuit board for removably coupling to the defibrillator and for coupling the electrode to the defibrillator;

reading information about the electrode with the defibrillator from a configuration circuit; and

sending shock energy to the electrode if it is determined that one or more predetermined conditions are met.

2. The method of claim 1, further comprising sending information from the defibrillator to the configuration circuit.

3. The method of claim 1, further comprising storing the information received from the defibrillator in the configuration circuit.

4. The method of claim 1, wherein reading information about the electrode with the defibrillator from the configuration circuit comprises reading an expiration date.

5. The method of claim 1, further comprising determining if the electrode has expired.

6. The method of claim 1, further comprising reading a usage history of the electrode.

7. The method of claim 1, further comprising determining if the electrode has not been used.

8. The method of claim 1, wherein reading information with the defibrillator from a configuration circuit comprises the step of reading a defibrillator pad type.

9. The method of claim 1, further comprising adjusting a level of defibrillation shock energy based on information read from the configuration circuit.

10. The method of claim 1, further comprising determining if a self test is being executed and if information read from the configuration circuit indicates the electrode is one of expired and used.

11. The method of claim 3, wherein storing the information received from the defibrillator in the configuration circuit comprises storing a record of usage history for the electrode.
