Abstract
Abstract This is an electrode arrangement particularly useful in providing a reliable electrical contact to be made to the skin of a person or animal in order to permit, for example, an electroencephalogram or electrocardiogram reading to be made by means of an EEG or ECG system connected to the electrode arrangement. The electrode arrangement utilizes an elongated post and an apertured ring having a plurality of tabs for making a strong mechanical attachment to the post. Also disclosed is a combined electrode arrangement and adhesive pad assembly. A feature of this combination is the use of the electrode arrangement described above in combination with the use of a pair of electrically conductive irregular shaped gel pads with the gel pads being located on opposite sides of the flange associated with the post of the electrode arrangement. The gel pad configuration provides a short electrical contact path to be created between the skin of the animal or person that is being monitored and the electrode post.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
203 words
An electrode arrangement for use as a probe for sensing heart beats comprising, in combination, an electrode including a generally circular base flange and a solid integral upstanding central post, said base flange and solid integral upstanding central post being coated with conductive silver, gel pad means covering the bottom surface of the base flange and extending outwardly beyond the outer periphery of said flange, an adhesive pad having a central aperture receiving said central post, said adhesive pad being disposed adjacent the upper surface of said base flange, and retainer means having a central aperture receiving said central post and retaining said adhesive pad on said electrode below said retainer means and above said base flange, said gel pad being maintained in contact with the base flange of Said electrode by adherence between the outer peripheral portions of the gel pad and the adhesive pad, the adhesive pad extending peripherally outwardly beyond the gel pad for adherence with the skin of a patient, the upper end of said central post being electrically exposed on the upper end portion thereof above said retainer means so as to be adapted to be directly connected with the electrode connector of an EEG or ECG system.
Claim 2
Dependent Claim
203 words
An electrode arrangement for use as a probe for sensing heart beats comprising, in combination, an electrode including a generally circular base flange and a solid integral upstanding central post, said base flange and solid integral upstanding central post being coated with conductive silver, gel pad means covering the bottom surface of the base flange and extending outwardly beyond the outer periphery of said flange, an adhesive pad having a central aperture receiving said central post, said adhesive pad being disposed adjacent the upper surface of said base flange, and retainer means having a central aperture receiving said central post and retaining said adhesive pad on said electrode below said retainer means and above said base flange, said gel pad being maintained in contact with the base flange of Said electrode by adherence between the outer peripheral portions of the gel pad and the adhesive pad, the adhesive pad extending peripherally outwardly beyond the gel pad for adherence with the skin of a patient, the upper end of said central post being electrically exposed on the upper end portion thereof above said retainer means so as to be adapted to be directly connected with the electrode connector of an EEG or ECG system.
Claim 3
Dependent Claim
22 words
An electrode arrangement according to claim 1 wherein said retainer means includes a plurality of tabs extending inwardly towards said central aperture.
Claim 4
Dependent Claim
39 words
An electrode arrangement according to claim 1 wherein said retainer means includes four tabs spaced 90* apart in a circular configuration, said tabs being angularly displaced with respect to the plane of said retainer means by said central post.
Claim 5
Dependent Claim
38 words
An electrode arrangement according to claim 1 wherein said central post includes a knob shaped portion on the upper end to provide means for connecting said central post with an electrode connector of an EEG or ECG system.
Claim 6
Dependent Claim
55 words
An electrode arrangement according to claim 1 wherein said circular base flange and said solid integral upstanding central post are made of a material forming a base for an adherent silver encapsulating coating whereby said silver coating provides electrical connection with said gel pad and with an electrode connector of an EEG or ECG system.
