What Is the Draeger MS14556 Compatible 3-Lead ECG Leadwire?

The Draeger MS14556 compatible 3-lead ECG leadwire is a reusable, aftermarket lead set that carries cardiac signals from the patient’s snap electrodes to the Draeger ECG trunk cable and on to the monitor. It is a compatible replacement, not an original Draeger part, and it is built to the same fit, form, and function as the OEM MS14556 lead set. The three limb leads (RA, LA, and LL) support standard 3-lead monitoring in the OR, ICU, emergency department, step-down units, and general patient care areas.

Compatible Monitor Models

This compatible leadwire is confirmed for use with the Draeger Infinity M540 and Infinity M300, and with the Draeger MultiMed Plus and MultiMed Plus OR ECG systems. It connects through the matching Draeger trunk cable using the single-pin lead connector these systems use. Before ordering, biomedical technicians should confirm that the trunk cable in service accepts single-pin leads. Draeger dual-pin trunk cables need a different lead set.

Design and Construction

Each of the three leads is 3 ft (0.9 m) long and shielded, which helps keep the ECG trace clean in electrically noisy clinical settings. The trunk end has a molded Draeger single-pin (DIN-style) connector for a secure, strain-resistant fit. The patient end has snap connectors that press onto standard snap-style electrodes, giving a low-profile, secure attachment that many units prefer for longer monitoring periods. Facilities using tab electrodes should choose the grabber version of this lead set instead. The leads follow the AHA color code used in US facilities: white for right arm, black for left arm, and red for left leg. The gray TPU jacket is about 0.10 in (2.6 mm) in diameter and stays flexible and tangle-resistant through repeated cleaning. The lead set is latex-free, non-sterile, rated for adult and pediatric patients, and ships one per bag.

When to Replace Your Draeger 3-Lead ECG Leadwire

Reusable leadwires wear out from constant flexing, electrode snapping, and repeated disinfection. Replace the lead set when you see a noisy or intermittent ECG trace, frequent “lead off” alarms with good electrode contact, snap connectors that no longer grip the electrode firmly, cracked or stiff jacketing, exposed shielding, faded color coding, or a trunk connector that no longer seats firmly. A worn lead can mimic arrhythmias or hide real rhythm changes, so many facilities replace lead sets at the first sign of damage and keep spares on hand to avoid monitoring downtime.

Cross Reference and Interchange Part Numbers

This compatible 3-lead snap leadwire, IPR Medical SKU EL-DG3-90S-A, cross-references to Draeger part number MS14556 and Unimed part number DG3-90S. Materials managers and purchasing staff can use either number to confirm the match against existing inventory, work orders, or requisitions.
