A flexible tube with a pressure sensor, transducer, and/or thermistor located at its distal tip, used for intrapartum transcervical measurement of the intrauterine and amniotic pressures. It is attached at its proximal end via a signal cable to an external monitor that displays the pressure/temperature values, and is used to monitor the intensity, duration, and frequency of uterine contractions during labour. It may also be used for fluid infusion and sampling of amniotic fluid. It is typically made of plastic [e.g., polyethylene, polytetrafluoroethylene (PTFE) commonly known as Teflon, polyurethane] and/or silicone, and may include a catheter introducer/sheath. This is a single-use device.
