Electrode arrangement
First Claim
1. An electrode arrangement for making an electrical contact with the skin of the body of a patient comprising, in combination:
- an electrode element including a base flange with upper and lower surfaces and a central post upstanding from said upper surface, said electrode element being conductive;
a flexible adhesive pad for adhering to the body, said adhesive pad including a foam pad member having upper and lower surfaces and an adhesive layer provided on, and coextensive with, said lower surface of said foam pad member, said adhesive pad having a central aperture received by said central post, said central post extending through said central aperture such that a portion of said central post extends above said upper surface of said adhesive pad, said upper surface of said base flange disposed adjacent to, and adhering to, said adhesive layer, said adhesive pad extending beyond the periphery of said base flangea flexible, foam, O-ring-shaped member adhering to said adhesive layer of said adhesive pad such that said O-ring-shaped member circumscribes said base flange of said electrode element; and
a shielding means comprising a dome-shaped annular washer, comprised of a tough, rigid material, received by said central post adjacent said upper surface of said adhesive pad, said shielding means for shielding said base flange from forces to which said electrode arrangement can be exposed, said annular washer having an outside diameter generally equivalent to the outside diameter of said O-ring-shaped member for deflecting the forces away from said base flange to said O-ring-shaped member without decreasing the flexibility and the ability of said adhesive pad to conform to the body of a patient.

Abstract
An electrode arrangement is presented which provides for a reliable electrical contact with the skin of a person or animal. The electrode arrangement comprises, in combination, a central post with a base flange, an adhesive pad having a central aperture for receiving the central post, a gel member and a resilient o-ring shaped member. An alternate embodiment comprises a central post and base flange, an adhesive pad having a central aperture for receiving the central post, and a shield washer, with a central aperture for receiving the central post, mounted above the adhesive pad. Both embodiments minimize the effect of physical forces placed on the electrical contact.
