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 connector system comprising:

a defibrillator;

an electrode for administering shock energy and for monitoring a heart of a patient;

a housing;

a printed circuit board partially enclosed by the housing, a portion of the printed circuit board extending outside the housing; and

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

2. The connector system of claim 1, wherein the printed circuit board comprises a configuration circuit positioned on the printed circuit board and coupled to two or more contacts, the configuration circuit storing information about the defibrillator patient electrodes and being at least readable by the defibrillator.

3. The connector system of claim 2, wherein the information stored in the configuration circuit relates to one of age, origin of manufacture, purpose, and physical characteristics of the electrode.

4. The connector system of claim 2, wherein the configuration circuit comprises one or more memory devices.

5. The connector system of claim 2, wherein the configuration circuit is re-writeable.
