ECG electrode strip with elongated slots
First Claim
1. A harness for positioning on a chest of a patient for use with electrode pads which have conductive inner sides to make electrocardiographic measurements, comprising:
- a strip of a nonconductive film having a plurality of slots positioned for placement at selected anatomical positions;
a connector terminal at one edge of the strip for connection to a monitoring device;
a plurality of electrically conductive border traces, each formed on the strip and extending at least partially around one of the slots, the border traces being insulated from an inner side of the strip to avoid contact with the skin of the patient;
a plurality of conductive leads formed on the strip, each leading from the connector terminal, at least some of the leads leading to the border traces to electrically connect the border traces with the connector terminal; and
wherein each of the border traces is exposed on an outer side of the strip for electrical engagement with the conductive inner side of one of the electrode pads which may be selectively placed on the outer side of the strip at least partially extending over one of the slots so as to place the conductive inner side of the electrode pad in electrical contact with one of the border traces and in electrical contact with the skin of the patient.

Abstract
An ECG harness is positioned on the chest of patient for making electrocardiographic measurements. The harness includes a strip of nonconductive film having a plurality of slots spaced along the length of the strip at selected anatomical positions. A connector terminal is formed at one edge of the strip for connection to a monitoring device. Electrically conductive border traces extend around the slots. The border traces are exposed on the outer side of the strip and insulated from the inner side of the strip. Conductive leads extend from the connector terminal to the border traces. Electrode pads are placed on the outer side of the strip at least partially extending over the slots. Each of the electrode pads has a conductive inner side for electrical contact with one of the border traces and the skin of the patient.
