The present invention provides for an ECG electrode system that includes the use of electrodes adapted to attach to the body via suction. The invention includes a lightweight and compact air pump in combination with air connection hoses, a lightweight air distribution unit, associated electrode tubes, and respective electrodes adapted to be positioned by the Venturi principle, and corresponding electrical leads and recorders/monitors. The electrode leads can each be positioned within respective air connections hoses, e.g., in a manner that is concentric or coaxial with the axis of the connection hoses, in order to both protect the leads themselves and facilitate their positioning.

Venturi ECG electrode system

A contactor for establishing electrical communication with organic tissue, the contactor including a cup-shaped housing of one-piece rubbery material including a closing end-wall connected across an annular sidewall with rim defining an open mouth into a main recess. An electrode in the recess comprises a contact plate with first side facing the mouth to contact organic tissue, and a second side with a pair of leg-like extensions and a center limiter post all of one-piece molded plastics coated with a thin layer of conductor preferably silver/silver chloride to be electrically conductive on the exterior surface of the electrode. The legs of the electrode snap fit against to physically and electrically connect with an electrically conductive venturi tube mounted extending through the housing, the venturi tube having a suction port positioned such that when high pressure gas is passed through the venturi tube, a vacuum is created within the housing recess.
