LaborView™ Sensor System
Current electronic maternal-fetal monitoring devices use outdated sensors (a toco [strain gauge]) for contractions and Doppler-based ultrasound to pick up the fetal heart rate). These sensors are frequently inaccurate (with studies showing a failure rate up to 35%) and notorious for requiring frequent adjustments by the nurses. They don’t work well, if at all, with obese moms. Tight Velcro belts holding them on are uncomfortable, especially for obese moms. They also tether mom to the monitors, reducing mobility, and further increasing the nurse’s workload. The “gold standard” alternatives – the intra-uterine pressure catheter (IUPC) and fetal scalp electrode screwed into the baby’s scalp (FSE) – require adequate cervical dilation and ruptured membranes, increase costs, and risk infections.
OBMedical®’s LaborView™ sensor system is a wireless electrode-based system designed for labor and delivery departments. LaborView™ is an advanced maternal fetal sensor that externally measures labor contractions and the heart rates of the mother and child. The innovative technology offers superior signal capture and digital signal processing that is simple to set up, provides safe, continuous and reliable monitoring, and allows the mother mobility during labor.
The system has four components. The first component is a disposable electrode array that is comfortable and easy to apply by the caregiver.
The entire system including the electrode array,wireless transmitter, base station, and connector cables to standard maternal-fetal monitors is shown here.
The LaborView™ sensor system features include:
♥ Non-invasive, easy to apply, and more comfortable (particularly relative to the tight Velcro bands required to keep the toco and ultrasound in place and working properly)
♥ Much improved contraction waveforms, particularly in difficult-to-monitor obese patients because electrical signals propagate better through adipose tissue than pressure signals (mean positive percent agreement of approximately 90% of all contractions compared to approximately 70% for standard toco strain gauge when measured against an IUPC) in our clinical trials
♥ Much improved fetal heart rate monitoring, since the device need not be constantly readjusted to acquire or maintain the FHR (preliminary data indicate a mean positive percent agreement of 85% compared to 63% for ultrasound when measured against a fetal scalp electrode)
♥ LaborView stays in place during epidural placement
♥ Maternal heart rate monitoring and successful separation of FHR and MH
♥ Exceptional UA data capture, may allow you to delay or avoid IUPC
♥ Nurses love the fact that they don’t need to reposition the array “apply it once”
♥ Reduced trip risk
♥ Exceptional performance in high BMI patients (Class I, II, and III)
♥ Ambulatory patients mean improved patient satisfaction
♥ Minimized nursing interventions to maintain reliable signals or to permit patient movement
♥ Functionality when the standard toco and/or ultrasound does not work, reducing the need for an IUPC and/or FSE
♥ Minimal cost of adoption since the disposable electrode array and wireless interfaces compose a “sensor replacement” approach using the installed base of monitors
♥ No retraining of the OB physicians or nursing staff
♥ Connects to legacy monitors and central monitoring systems, no need to upgrade.
