Abstract

A device is provided for sensing an electrocardiogram signal of a patient. The device includes a substrate and a plurality of electrodes mounted to the substrate. The plurality of electrodes are configured to sense an electrocardiogram signal of a patient when the plurality of electrodes are placed in contact with the patient. The device may include a strap configured to wrap around a portion of the patient wherein the substrate mounts to the strap. The device further may include a respiration sensor mounted to the strap.

Claims

1. A device comprising:

a substrate; and

a plurality of electrodes mounted to the substrate and configured to sense an electrocardiogram signal of a patient when the plurality of electrodes are placed in contact with the patient.

2. The device of claim 1, wherein an electrode of the plurality of electrodes is formed of a non-ferrous conductive material.

3. The device of claim 2, wherein the non-ferrous conductive material is selected from the group consisting of silicon rubber, conductive epoxy, carbon black, and carbon rubber.

4. The device of claim 1, wherein an electrode of the plurality of electrodes has a circular shape having a diameter greater than or equal to two centimeters.

5. The device of claim 4, wherein the diameter greater than or equal to three centimeters and less than or equal to four centimeters.

6. The device of claim 1, wherein the plurality of electrodes are mounted to the substrate with a spacing of at least one centimeter between each electrode of the plurality of electrodes.

7. The device of claim 1, wherein an electrode of the plurality of electrodes has a rectangular shape having a length of at least 2.5 inches and a width of at least 0.5 inches.

8. The device of claim 1, wherein the plurality of electrodes extend from the substrate.

9. The device of claim 1, wherein the substrate is formed of a non-conductive material.

13. The device of claim 12, wherein the deformable material is a viscoelastic foam.

14. The device of claim 13, wherein the deformable material is encased in a film.

15. The device of claim 1, further comprising a first wire and a second wire mounted within the substrate, wherein the plurality of electrodes comprises at least a first electrode and a second electrode, and further wherein the first wire connects to the first electrode and the second wire connects to the second electrode.

16. The device of claim 15, wherein the first wire and the second wire extend from the substrate.

17. The device of claim 15, wherein the first wire and the second wire connect to a common cable which extends from the substrate.

18. The device of claim 15, wherein the first wire comprises a non-ferrous conductive material.

19. The device of claim 15, further comprising an electro-optical converter connected between the first electrode and the first wire, wherein the first wire comprises an optical fiber.

20. The device of claim 1, further comprising a strap configured to wrap around a portion of the patient wherein the substrate mounts to the strap.

21. The device of claim 20, wherein the substrate is mounted to the strap in a position such that the plurality of electrodes are placed in contact with a back and a left side of the patient when the strap is positioned in contact with the patient.

22. The device of claim 20, further comprising a respiration sensor mounted to the strap.
