The Edan TOCO Probes provide precise tracking of maternal uterine activity and labor contraction cycles. Built with high-sensitivity strain gauge sensors and an ergonomic flat profile, these transducers attach securely to the patient abdominal wall to deliver real-time external pressure telemetry. While the standard baseline configuration manages standalone external contractions, the upgraded multi-channel assembly interfaces directly with internal fetal monitoring modules to capture specialized fetal electrocardiogram and intrauterine pressure waveforms during complex intrapartum evaluations.
