Suction manifold assembly for an electrocardiogram electrode application system

A suction manifold assembly for an electrocardiogram (ECG) electrode application system, comprising:

• a manifold;
• a plurality of pneumatic valves integrated within the manifold;
• a common manifold chamber fluidly coupled to each pneumatic valve of the plurality of pneumatic valves, and wherein each pneumatic valve is configured to be coupled via a lead wire to a respective suction electrode;
• wherein the suction manifold assembly is configured to be disposed within a housing of an electrode distributor of the ECG application system, and wherein pneumatic valves of the plurality of pneumatic valves are disposed adjacent to each other along a horizontal plane in both a first direction and a second direction, the first direction being orthogonal to the second direction;
• and
• wherein the plurality of pneumatic valves comprises both a first set of pneumatic valves disposed along a first horizontal plane in both the first direction and the second direction and a second set of pneumatic valves disposed along a second horizontal plane in both the first direction and the second direction, the first horizontal plane being parallel with the second horizontal plane, and wherein the first set of pneumatic valves is disposed in an opposite orientation from the second set of pneumatic valves.

An electrocardiogram (ECG) electrode application system, comprising:

• an electrode distributor, comprising:
• a housing;
• and
• a suction manifold assembly disposed within the housing, wherein the suction manifold assembly comprises a manifold, a plurality of pneumatic valves integrated within the manifold, and the manifold comprises a common manifold chamber fluidly coupled to each pneumatic valve of the plurality of pneumatic valves, and each pneumatic valve comprises a venturi passage, wherein each pneumatic valve comprises a valve body portion coupled to an inlet portion, and each pneumatic valve comprises an outlet portion and a narrow portion disposed between the valve body portion and the outlet portion, and wherein the narrow portion has a diameter that is less than a respective diameter of each of the inlet portion, the valve body portion, and the outlet portion;
• an orifice disposed within the common manifold chamber;
• and
• a plurality of suction electrodes, each suction electrode of the plurality of suction electrodes 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;
• wherein 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, and the orifice is configured to set a level of change in the air pressure to trigger the application of the suction pressure applied within a respective electrode suction dome.
