PS320 Fetal Simulator
At week five, a fetus’ heart starts beating, increasing to 155 to 195 beats per minute prior to birth. The strength and number of beats can be measured by a fetal electronic monitor to determine whether a fetus is in distress. The PS320 fetal simulator mimics fetal and maternal heartbeats (ECG), along with uterine activity during labor to accurately test and troubleshoot fetal electronic monitors.
The PS320 is a fetal monitor simulator that simulates fetal and maternal ECG, as well as uterine activity, in order to test and troubleshoot fetal electronic monitors and train clinical staff. The unit is battery operated and small enough to fit in a pocket, making it portable for on-the-go testing. The PS320 simulates several fetal parameters, including twins, as well as a wide range of clinical scenarios for training labor-and-delivery staff in how to recognize normal and abnormal responses. An optional mechanical heart creates fetal heart sounds for testing fetal monitor ultrasound cables and transducers. PS320 offers an easy user interface, providing a 2 x 16-character LCD display with adjustable contrast. The unit operates on a 9 V battery with low-battery monitoring or functions with the supplied battery eliminator.
