Suction manifold assembly for an electrocardiogram electrode application system

Abstract

An ECG electrode application system includes an electrode distributor including a housing and a suction manifold assembly disposed within the housing. The suction manifold assembly includes a manifold, a plurality of pneumatic valves integrated within the manifold, and the manifold includes a common manifold chamber fluidly coupled to each pneumatic valve, and each pneumatic valve includes a venturi passage. The ECG electrode application system includes a plurality of suction electrodes, each suction electrode having an electrode suction dome and coupled to the electrode distributor via a lead wire, and each lead wire is coupled to a respective pneumatic valve. Each electrode suction dome is configured when pressed to cause a change in air pressure that results in a suction pressure being applied within a respective electrode suction dome to adhere a corresponding suction electrode to a subject at a pressure determined by the venturi passage of a corresponding pneumatic valve.
