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.

A multipart, non-uniform patient contact interface and method of use are disclosed.

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that when applied to living tissue or similar surfaces displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.
