Abstract
Abstract A biomedical monitoring or stimulating electrode that adheres to a person's skin is disclosed. The electrode is made of a thin, flat flexible material and includes a die-cut patch having a non-conductive adhesive coating applied on one side of the patch, a foundation component formed into four integral functional areas, a conductive component made up of an electrically conductive material with three contiguous portions, and a conductive media. Also disclosed is a connector that interfaces with a tab portion of the electrode. The connector includes an electrically conductive element having an inclined surface upon which the tab of the electrode rests. A slider is movable between two positions such that when in its closed position, the electrode neck and head is trapped in the connector and the slider exerts a force on the inclined surface of a cavity of the connector, providing electrical connection to electrode. Thus, the cavity and firm compression act to prevent the electrode from becoming disengaged from the connector.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
141 words
A connector for mechanically and electrically interfacing with a biomedical electrode, the electrode having an electrically conductive tab portion, the connector comprising: a. a slider having an undersurface with an inclined plane; and b. a conductor component having a cavity with an electrically-conductive surface with an inclined plane, the angle of incline of the slider undersurface being equal to the angle of incline of the surface of the cavity, wherein the electrically conductive tab portion of the electrode is disposed adjacent to and in an abutting relationship to the inclined surface of the cavity, wherein the slider, when moved to close the cavity, has its inclined undersurface interface with the inclined plane of the cavity such that the slider exerts a retaining force on the electrically conductive tab portion of the electrode to prevent movement of the electrically conductive tab portion.
Claim 2
Dependent Claim
141 words
A connector for mechanically and electrically interfacing with a biomedical electrode, the electrode having an electrically conductive tab portion, the connector comprising: a. a slider having an undersurface with an inclined plane; and b. a conductor component having a cavity with an electrically-conductive surface with an inclined plane, the angle of incline of the slider undersurface being equal to the angle of incline of the surface of the cavity, wherein the electrically conductive tab portion of the electrode is disposed adjacent to and in an abutting relationship to the inclined surface of the cavity, wherein the slider, when moved to close the cavity, has its inclined undersurface interface with the inclined plane of the cavity such that the slider exerts a retaining force on the electrically conductive tab portion of the electrode to prevent movement of the electrically conductive tab portion.
