Obstetrical instrument system and method

摘要

The childbirth process is monitored by applying one or more probes to the mother and monitoring the locations of the probes by transmitting non-ionizing fields such as magnetic fields between the probes and reference elements in proximity to the mother. The magnitude and direction of movement of the probes indicates the magnitude and direction of uterine contractions. Fetal position and cervical dilation may be monitored by providing additional probes attached to the fetus and to the cervix.
