What Is a Toco Transducer?

A tocodynamometer, commonly called a toco, is an external uterine activity sensor used during labor and delivery to detect, time, and record uterine contractions. Strapped to the maternal abdomen with a monitoring belt, the toco transducer responds to changes in abdominal wall tension caused by uterine contractions, transmitting data to the fetal monitor to display contraction frequency, duration, and relative intensity in real time. It is one of two transducers used in standard external fetal monitoring — the other being an ultrasound transducer that tracks the fetal heart rate.

GE Corometrics 2264LAX — Wings (Loop) Style

The 2264LAX is GE Healthcare’s Corometrics Nautilus-series toco transducer featuring a loop (wing) style proximal connector. The wing slides into the corresponding slot on the fetal monitor, creating a secure, tool-free connection that resists accidental disconnection during patient repositioning. The flat, low-profile transducer housing is designed with patient comfort in mind, reducing bulk and pressure against the abdomen during prolonged monitoring. The watertight construction supports thorough surface disinfection between patients.

This compatible replacement transducer meets the same functional role as the OEM unit at a more accessible price point, allowing facilities to maintain adequate transducer inventory without depending on a single-source supplier. It ships individually bagged, non-sterile and ready for immediate clinical use.
