What Is the GE Corometrics 1590AAO Compatible Fetal Leg Plate Cable?

The GE Corometrics 1590AAO compatible fetal leg plate cable is a reusable, aftermarket cable for direct fetal ECG (DECG) monitoring during labor. After the membranes rupture and a fetal spiral electrode (FSE) is applied to the fetal scalp, the electrode wires connect to this cable’s leg plate, which is secured to the mother’s inner thigh. The cable carries the fetal ECG signal to the monitor, which derives a beat-to-beat fetal heart rate that is often more reliable than external ultrasound, especially during maternal movement or with higher-BMI patients. It is a compatible replacement, not an original GE part, and it is built to the same fit, form, and function as the OEM 1590AAO Qwik Connect Plus cable.

Compatible Monitor Models

This compatible leg plate cable is confirmed for use with GE Healthcare Corometrics fetal monitors, including the 115, 116, 118, 120 Series, 150, 151, and 170, as well as the 250cx and 259cx. It is designed for Qwik Connect Plus spiral electrodes. Facilities using other spiral electrode styles should confirm electrode compatibility before ordering.

Design and Construction

The cable has an integrated leg plate that lies flat against the maternal thigh and provides the connection point for the Qwik Connect Plus spiral electrode wires. The 8.2 ft (2.5 m) cable gives enough reach from the bed to the fetal monitor for position changes and routine care during labor. Because the leg plate cable is reusable and only the spiral electrode is single-use, facilities can keep per-patient disposable costs down. The cable is cleaned between patients according to facility protocol and ships one per bag.

When to Replace Your Fetal Leg Plate Cable

Leg plate cables are exposed to fluids, frequent cleaning, and repeated flexing near the leg plate and monitor connector. Replace the cable when the DECG signal is noisy, intermittent, or drops out even with a properly applied spiral electrode and good reference contact. Also replace it when the monitor shows signal-loss messages that clear with a different cable, or when you find a cracked leg plate, damaged electrode connection points, a split cable jacket, or bent connector pins. Testing with a fetal simulator or a known-good cable quickly confirms whether the cable is at fault.
