Contact electrode
First Claim
1. An electrode assembly for connection in use to a separate electrical device, said electrode assembly comprising two spaced conductive layers for making electrical contact with a patient in use, a backing sheet overlying both said contact electrode layers, said backing sheet electrically conductively interconnecting said contact electrode layers and forming the sole electrically conductive connection between said contact electrode layers, said backing sheet being readily peelable from said conductive layers, a test circuit for passing a current through a circuit including both contact electrode layers and an electrically conductive portion of said backing sheet to test the conductive condition of the contact electrode layers, and connection means for connecting said assembly to said test circuit, said test circuit including means for electrically testing and indicating the condition of said contact electrode layers.

Abstract
An electrode generally comprises a body, which makes up the electrode and which is formed as a thin flexible polymeric substance such as urethane foam. The electrode body includes a central inner conductive area, which is associated with a first electrode connector. Around the inner conductive area is a non-conductive area formed as a ring around the inner conductive area and there is also an outer conductive area provided as a ring, concentrically arranged around the non-conductive area. Electrode connector (6B) is connected to the outer conductive ring. The electrode body, which has a release tag and is supported on a backing sheet and body can be peeled off the backing sheet using the release tag. The condition of the electrode can be evaluated using a test device, which can for example measure electrical impedance across the electrode via electrodes (6A) and (6B).
