Abstract

An electrode system and the method of arranging the electrodes on the skin of a patient. The electrode system contains a plurality of electrode pads. At least some of the electrode pads have a convex side edge of a predetermined radius of curvature. At least some of the electrode pads have a concave side edge with the same predetermined radius of curvature. When applied to a patient'"'"'s skin, two electrode pads are placed in adjacent abutment. The concave side edge of one electrode pad receives the convex side edge of the adjacent electrode pad. This produces a gapless adjoining connection between electrode pads that can be maintained throughout a wide range of orientations.

Claims

1. An electrode device for providing electrical contact with a person'"'"'s skin, comprising:

an attachment base having a first straight side edge, an opposite second straight side edge, a curved concave side edge extending between said first straight side edge and said second straight side edge and a curved convex side edge extending between said first straight side edge and said second straight side edge, wherein said first straight edge, said second straight edge, said curved concave side edge and said curved convex side edge define a complete periphery of said attachment base, and wherein said curved concave side edge and said curved convex side edge have a common radius of curvature; and

a terminal extending upwardly from said attachment base that enables said electrode device to be individually connected to a test wire lead.

2. An electrode system for providing electrical contact with a person'"'"'s skin, comprising:

a plurality of electrode pads that are electrically isolated from one another, each of said electrode pads including;

a terminal connection;

a first straight side edge, an opposite second straight side edge, a curved concave side edge and a curved convex side edge, wherein said first straight edge, said second straight edge, said curved concave side edge and said curved convex side edge define a complete periphery of an electrode pad;

wherein said curved concave side edge and said curved convex side edge have a common radius of curvature; and

wherein said concave side edge of a first said electrode pads receives said convex side edge of a second of said electrode pads creating a gapless seam between said first and said second of said electrode pads when said first and said second of said electrode pads are placed in adjacent abutment; and

wherein said gapless seam is maintained throughout a relative range of motion of at least 90 degrees between said first and said second of said electrode pads.

3. The system according to claim 2, wherein each of said plurality of electrode pads have identical shapes.

4. The system according to claim 2, wherein each of said electrode pads includes a separate, independent terminal that extends upwardly therefrom.

5. A method of connecting electrodes to the human body, comprising the steps of:

providing a plurality of electrode pads, wherein, each of said electrode pads is identical and has a first straight side edge, an opposite second straight side edge, a curved concave side edge and a curved convex side edge, wherein said first straight edge, said second straight edge, said curved concave side edge and said curved convex side edge define a complete periphery of an electrode pad, and wherein said curved concave side edge and said curved convex side edge have a common radius of curvature;

attaching a first of said electrode pads to a patient'"'"'s body;

attaching a second of said electrode pads to said patient'"'"'s body immediately adjacent said first of said electrode pads within a range of relative orientations, wherein said concave side edge of said first of said electrode pads receives said convex side edge of a second of said electrode pads creating a gapless adjoining connection between said first and said second of said electrode pads throughout said relative range of orientations.

6. The method according to claim 5, further including the step of connecting each of said plurality of electrode pads to a separate test lead.
