Abstract
A disposable electrode assembly for contacting a patient and for receiving electrical signals from at least one remotely located electrode, the remotely located electrode having leads. The electrode assembly has a thin, flexible, leg plate with a bottom surface contacting the patient without adhesive. At least two triangular-shaped springs are carried by the leg plate for electrically and mechanically connecting the leads from the remotely located electrode to the leg plate. At least two latches, each adapted to snap over one of the triangular-shaped springs, provide an audio indication of flap closure and keep a flap closed over each of the triangular-shaped springs. A reference electrode electrically contacts the patient through a skin-contacting surface when the electrode assembly is secured to the patient. The reference electrode is electrically coupled to, but mechanically decoupled from, the leg plate. Separate, insulated wires electrically engage the springs and the reference electrode. The wires are joined in a cord providing electrical connection to an external monitoring device. An attachment member secures the electrode assembly to the patient.
