Abstract

This invention is directed to a medical electrode system having a flexible substrate with two electrodes in electrical communication disposed at either end along its length. The electrode system also has one or more sensors for detecting the rate and pressure at which CPR is administered. The electrode is adjustable in length and protects the user from the potential of incidental shock when using the electrode in conjunction with a defibrillator.

Claims

1. A defibrillator electrode system comprising an electrode pad having:

an elongated flexible substrate adapted to be applied across a chest of a patient, the elongated flexible substrate having a first end and a second end;

a first and a second electrode disk capable of delivering a defibrillation shock in electrical communication disposed on the elongated flexible substrate, wherein the first electrode is disposed on the elongated flexible substrate at the first end and the second electrode is disposed on the elongated flexible substrate at the second end;

at least one sensor for detecting CPR compressions disposed on the elongated flexible substrate between the first and second electrode disk; and

a first and a second conductive gel layer adhered to the first and second electrode disks.

2. The defibrillation electrode system of claim 1 wherein the at least one sensor detects rate at which CPR compressions are administered.

3. The defibrillation electrode system of claim 1 wherein the at least one sensor detects the force at which CPR compressions are administered.

4. The defibrillator electrode system of claim 1 wherein the electrode pad is adhered to an electrode placard having imprinting to show the proper placement of the electrode.

5. The defibrillator electrode system of claim 4 wherein the imprinting on the electrode placard includes an image of a portion of the human body.

6. The defibrillation electrode system of claim 1 wherein the electrode pad is adjustable in length.

7. The defibrillation electrode system of claim 6 wherein the electrode pad has a plurality of folded sections.

8. The defibrillation electrode system of claim 6 wherein the electrode pad has an elasticized section between the two ends of the electrode pad.

9. The defibrillation electrode system of claim 8 wherein the elasticized section is integrally formed with the flexible sections at either end.

10. The defibrillation electrode system of claim 4 wherein the imprinting on the electrode can be interpreted by an AED operator without reviewing other information.

11. The defibrillation electrode system of claim 1 wherein the electrode pad is releasable adhered to a placard.

12. The defibrillator electrode system of claim 10 wherein the placard further includes a storage area.

13. The defibrillation electrode system of claim 10 wherein the placard further includes scaled imprinting corresponding to the anatomy of a human body.

14. The defibrillation electrode system of claim 1 wherein the flexible substrate extends beyond a perimeter of the electrode disks at least 5 cm.

15. The medical electrode system of claim 14 wherein the sensor detects the rate at which CPR compressions are administered.

16. The medical electrode system of claim 14 wherein the sensor detects the force at which CPR compressions are administered.

17. A releasable placard for use in a medical electrode system comprising at least one electrode, the releasable placard having:

a releasing surface for adhering to the at least one electrode; and

a storage area for holding equipment to be used when the electrode system is deployed.

18. The releasable placard of claim 17 wherein at least one electrode pad is adhered thereto.

19. The releasable placard of claim 17 wherein two electrode pads are adhered thereto.

20. The releasable placard of claim 17 wherein the placard is imprinted to show a portion of the human body.
