LOW NOISE OXIMETRY CABLE INCLUDING CONDUCTIVE CORDS

摘要

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.

主权项

1. A cable for communicating sensitive low level signals, the cable comprising:
at least one wire including a conductor configured to communicate the sensitive signal and an insulator surrounding the conductor; at least one hollow conductive cord assembled with said at least one wire; and a shield at least partially surrounding said assembly of at least one wire and at least one hollow conductive cord; and a jacket surrounding said shield, wherein said shield is capable of being set to a predetermined voltage to drain potential buildup of triboelectric charge on said jacket.
