What Is the GE Corometrics 1591AAO Compatible Fetal Leg Plate Cable?

The GE Corometrics 1591AAO compatible fetal leg plate cable is a reusable, aftermarket cable for direct fetal ECG (DECG) monitoring during labor. Once the membranes have ruptured and a fetal spiral electrode (FSE) is applied to the fetal scalp, the electrode wires clip into this cable’s leg plate, which is strapped to the mother’s inner thigh. The cable carries the fetal ECG signal to the monitor, which calculates a beat-to-beat fetal heart rate that holds up better than external ultrasound during maternal movement or in 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 1591AAO Qwik Connect Plus cable. The part number is frequently typed with a zero as 1591AA0, and both spellings refer to the same cable.

Compatible Monitor Models

This compatible leg plate cable is confirmed for use with GE Healthcare Corometrics 120 Series fetal monitors, which use the rectangular DECG input connector. It is the counterpart to the 1590AAO cable, which has a round connector for other Corometrics models. Before ordering, check the shape of the DECG port on your monitor to confirm you need the rectangular version. The cable is designed for Qwik Connect Plus spiral electrodes, so facilities using other spiral electrode styles should confirm electrode compatibility as well.

Design and Construction

The cable has an integrated leg plate that sits flat against the maternal thigh and provides the connection point for the Qwik Connect Plus spiral electrode wires. At the monitor end, a rectangular connector seats in the 120 Series DECG port. The 8.2 ft (2.5 m) cable gives enough reach from the bed to the 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 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 the 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, 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.

Cross Reference and Interchange Part Numbers

This compatible fetal leg plate (DECG) cable, IPR Medical SKU FDELA-GE01-SGE, cross-references to GE Healthcare Corometrics part numbers 1591AAO (also written 1591AA0) and 2109005-001. Materials managers and purchasing staff can use either number to confirm the match against existing inventory, work orders, or requisitions. For Corometrics monitors with a round DECG connector, IPR Medical also stocks the compatible 1590AAO leg plate cable.
