Abstract
Abstract In an electrode apparatus for use in deriving electrical signals from an animal or human subject including a disposable interface unit and a reusable electrode plug unit where the disposable interface unit comprises: a unitary fabricated nonconductive member having a reservoir adapted to contain a viscous electrolyte, and outlet means extending from the reservoir to an upper surface of the member including a self-sealing closure means adapted to detachably receive the electrode plug when inserted therein.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
105 words
In an electrode apparatus for use in a system for deriving electrical signals from a human or animal subject, including a disposable interface unit and a reusable electrode plug unit, said disposable interface unit comprising: a unitary fabricated nonconductive member having an upper surface including outlet means and a bottom surface adapted for placement on the subject a recess at the bottom surface defining in said member a reservoir adapted to contain a viscous electrolyte, said outlet means extending from said reservoir to the upper surface of said member and including self-sealing closure means adapted to detachably receive the electrode plug unit when inserted therein.
Claim 2
Dependent Claim
105 words
In an electrode apparatus for use in a system for deriving electrical signals from a human or animal subject, including a disposable interface unit and a reusable electrode plug unit, said disposable interface unit comprising: a unitary fabricated nonconductive member having an upper surface including outlet means and a bottom surface adapted for placement on the subject a recess at the bottom surface defining in said member a reservoir adapted to contain a viscous electrolyte, said outlet means extending from said reservoir to the upper surface of said member and including self-sealing closure means adapted to detachably receive the electrode plug unit when inserted therein.
Claim 3
Dependent Claim
39 words
A unit according to claim 1 wherein: said outlet means comprises an elongated neck and said self-sealing closure means defines an inwardly protruding portion forming a resilient circular ridge to bias said closure means in a normally closed configuration.
Claim 4
Dependent Claim
41 words
A unit according to claim 2 wherein said electrode plug unit includes a surface formed on said plug unit to complement said outlet means when said self-sealing closure means is biased in an open condition for tight fitting mechanical engagement therewith.
Claim 5
Dependent Claim
129 words
In an electrode apparatus for use in a system for deriving electrical signals from a human or animal subject including a disposable interface unit and a reusable electrode plug unit said disposable interface unit comprising: a unitary fabricated resilient, nonconductive disclike member including outlet means and having a bottom surface adapted for placement on the subject, a viscous electrolyte, a recess at the bottom surface defining in said member a reservoir containing said viscous electrolyte, adhesive means extending about the recess at said bottom surface, protective cover means overlying said recess and releasably held to said adhesive means, and said outlet means extending from said reservoir to an upper surface of said member and including self-sealing closure means adapted to detachably receive the electrode plug unit when inserted therein.
Claim 6
Dependent Claim
129 words
In an electrode apparatus for use in a system for deriving electrical signals from a human or animal subject including a disposable interface unit and a reusable electrode plug unit said disposable interface unit comprising: a unitary fabricated resilient, nonconductive disclike member including outlet means and having a bottom surface adapted for placement on the subject, a viscous electrolyte, a recess at the bottom surface defining in said member a reservoir containing said viscous electrolyte, adhesive means extending about the recess at said bottom surface, protective cover means overlying said recess and releasably held to said adhesive means, and said outlet means extending from said reservoir to an upper surface of said member and including self-sealing closure means adapted to detachably receive the electrode plug unit when inserted therein.
Claim 7
Dependent Claim
29 words
A unit according to claim 4 wherein: said outlet means comprises an elongated neck and said self-sealing closure means includes an inwardly protruding portion forming a doughnutlike closed hole.
