For some patient monitoring monitors, we cannot directly plug the lead wire into the monitor, and we require a trunk cable to connect the monitor and lead wire. The trunk cable is an accessory part of the ECG system. Unimed supplies the trunk cable for most monitoring systems includes Philips, GE, Datascope, Medtronic, Draeger, Abbott, and more.Unimed medical trunk cables are adaptable to OEM and compatible lead wires directly with outstanding wear resistance. The fully shielded cables are anti-interference and have a long service life. They are a convenient and cost-effective solution.
