Digital electronic fetal heart rate and uterine contraction monitoring system

摘要

A digital electronic fetal heart rate and uterine contraction monitoring system with an electronic fetal monitor, a contraction monitoring sensor and a fetal heart rate sensor. A controller configured to receive fetal heart rate data and uterine contraction pressure, identify a contraction start time and end time, and calculate each rest interval in seconds between contractions. The system compares rest intervals to a safe preset limit for rest intervals, calculates a median rest interval and an average rest interval for each fifteen-minute period of labor, and presents a contraction and rest interval graph to a display. The system can activate an alarm on an electronic fetal monitor display or a third party display and can pause a pump that is delivering a drug to increase uterine contractions when a significant criteria of excessive uterine activity is detected outside preset limits to assure adequate blood flow to the fetal brain.
