Abstract

Disposable biomedical pads include a conductive outer layer with an adhesive conductive protected layer on a major portion of the outer layer, with a double-sided release layer over the protected layer. Two pads are folded against each other, with the edges sealed to protect the gel layer from the environment. In use, the release layer is discarded, the gel layer placed against the skin, and in the case of defibrillation pads, the paddles are applied directly to the outer conductive layer. The outer layer serves as the packaging layer as well as the dispersive electrode.

Claims

1. A medical pad unit, comprising:

first and second sections, wherein each section includes an outer layer, a protected layer overlaying at least a major portion of said outer layer;

said outer layer being impermeable to air and moisture;

said first and second sections being folded against each other such that an edge portion of said protected layers are touching; and

said outer layers of said first and section sections are sealed to each other along said edge portion of said outer layers.

2. A medical pad unit according to claim 1, further comprising a double-coated release layer overlaying each of said protected layers.

3. A medical pad unit according to claim 1, further comprising a double-coated release layer overlaying at least one of said protected layers.

4. A medical pad unit according to claim 3, wherein said release layer overlays at least part of said outer layer not overlain by said protected layer.

5. A medical pad unit according to claim 3, further comprising a border overlaying a part of said outer layer which is not overlain by said protected layer, wherein said release layer overlays said border.

6. A medical pad unit according to claim 5, wherein said border is of a dielectric material.

7. A medical pad unit according to claim 3, further comprising a fold line in said outer layer separating said first and second sections from each other.

8. A medical pad unit according to claim 7, further comprising a plurality of perforations in said fold line.

9. A medical pad unit according to claim 3, further comprising a plurality of perforations in said outer layer separating said first and second sections from each other.

10. A medical pad unit according to claim 3, wherein said protected layer is an adhesive conductive gel.

11. A medical pad unit according to claim 3, wherein said outer layer is electrically conductive.

12. A medical pad unit according to claim 11, wherein said protected layer is an adhesive conductive gel.

13. A medical pad unit according to claim 12, wherein said medical pad unit is a defibrillation pad unit.

14. A medical pad unit according to claim 12, wherein said medical pad unit is a tab electrode unit.

15. A medical pad unit according to claim 1, wherein said edge portions of said outer layers are sealed by an adhesive.

16. A medical pad unit according to claim 1, wherein said edge portions of said outer layers are heat-sealed.

17. A medical pad unit according to claim 1, further comprising an electrode fastened to an outside of said outer layer.

18. A medical pad unit, comprising:

first and second sections, wherein each section includes an outer layer, a protected layer overlaying at least a major portion of said outer layer, and a release layer overlaying at least said protected layer;

said outer layer being impermeable to air and moisture;

said first and second sections being folded against each other such that said release layers are touching; and

said release layers of said first and section sections are sealed to each other along an edge portion of said release layers.

19. A medical pad unit according to claim 18, wherein said edge portions of said release layers are sealed by an adhesive.

20. A medical pad unit according to claim 18, wherein said edge portions of said release layers are heat-sealed.

21. A medical pad package, comprising:

a sheet of a material which is impermeable to air and moisture;

said sheet including first and second sections separated by a fold line;

a protected coating disposed in at least one first location on said first section and in a corresponding at least one second location on said second section;

a double-sided release layer disposed over each of said protected coatings;

said first section being folded along said fold line over said second section, such that an edge portion of said first section of said sheet touches an edge portion of said second section of said sheet; and

said edge portion of said first section is sealed to said edge portion of said second section.

22. A medical pad package according to claim 21, wherein said material is electrically conductive.

23. A medical pad package according to claim 22, wherein a number of each of said first and second locations is one, and said medical pad package contains two defibrillation pads.

24. A medical pad package according to claim 23, further comprising first and second electrodes fastened to said electrically conductive material on an opposite side of said material from said first and second locations, respectively.

25. A medical pad package according to claim 22, wherein a number of each of said first and second locations is five, and said medical pad package contains ten tab electrodes.

26. A medical pad package according to claim 25, further comprising five electrodes fastened to said electrically conductive material on an opposite side of said material from said five first locations, and comprising five electrodes fastened to said electrically conductive material on an opposite side of said material from said five second locations.
