Designed to facilitate demonstration and practice of palpating the internal birthing canal. The simulator
clearly shows the relationship between the fetal head and the ischial spines of the pelvic bone of the mother
during the birth process. The realism of this simulator will help students bridge the gap from classroom to
bedside with ease and comfort. The simulator is designed to highlight the ischial spines which are of great
obstetrical importance. The line drawn between the ischial spines typically represents the shortest diameter
of the pelvic cavity. The ischial spines can be readily felt during a vaginal examination, and serve as
valuable landmarks in ascertaining the level to which the presenting part of the fetus has descended into the
pelvis. The Birthing Station Simulator features a fetal head which will lock in any one of three lock stations.
Minus Two Station shows the position of the fetal head when it lies above the ischial spines. Zero Station
shows the fetal head directly between the ischial spines. Plus Three Station shows the fetal head below the
ischial spines ready to enter into the birthing canal.
