Abstract

A defibrillation electrode for application to the front of the chest of a patient, the electrode comprising a metallic layer, a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient, an adhesive layer surrounding the conductive liquid-containing layer and having a layer of adhesive configured to adhere the electrode to the patient, a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal, wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and wherein the lateral perimeter is generally triangular.

Claims

1. A defibrillation electrode for application to the front of the chest of a patient, the electrode comprising

a metallic layer,

a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient,

an adhesive layer surrounding the conductive liquid-containing layer-and having a layer of adhesive configured to adhere the electrode to the patient,

a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal,

wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and

wherein the lateral perimeter is generally triangular.

2. The electrode of claim 1 wherein the lateral perimeters of the adhesive and release layers are also generally triangular.

3. The electrode of claim 2 further comprising three or more ECG monitoring electrodes, with one monitoring electrode located adjacent each of the three corners of the triangular perimeter.

4. The electrode of claim 3 further comprising an electrical conductor electrically connected to the metallic layer and extending from the electrode at a location approximately midway along one edge of the triangular perimeter.

5. The electrode of claim 1 wherein the defibrillation electrode is packaged with a second defibrillation electrode configured to be placed on a second location on the patient, and the second electrode has a lateral perimeter that is other than generally triangular.

6. The electrode of claim 5 wherein the second electrode has a generally square perimeter.

8. The electrode of claim 1 wherein the defibrillation electrode is packaged with a second defibrillation electrode configured to be placed on a second location on the patient, and the second electrode has a lateral perimeter that is other than generally crescent shaped.

9. The electrode of claim 5 wherein the second electrode has a generally square perimeter.

7. A defibrillation electrode for application to the front of the chest of a patient, the electrode comprising

a metallic layer,

a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient,

an adhesive layer surrounding the conductive liquid-containing layer and having a layer of adhesive configured to adhere the electrode to the patient,

a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal,

wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and

wherein the lateral perimeter is generally crescent shaped.
