Low noise oximetry cable including conductive cords
ActiveUS7919713B2Line/current collector detailsDiagnostic recording/measuringLow noiseElectrical conductor
In an embodiment, one or more conductive cable cords are twisted with the sensitive signal carrying cables. The cords may advantageously comprise dummy wires, or very flexible hollow cables without an inner conductor. As the conductive cords do not carry and inner conductor, the conductive cords are individually flexible and small, resulting in a twisted bundle that more is flexible while potentially having a smaller outer diameter.
