| 摘要 |
This invention is a method of monitoring the progress of labor in a mother during childbirth, by attaching a position sensor (PS1-PS4) to a predetermined point of the mother's pelvic bones; monitoring the location of the position sensor in three-dimensional space relative to a reference; and monitoring the location of the fetal presenting part (4) with respect to the predetermined point on the mother's pelvic bones. The location of the fetal presenting part may be indicated by a similar position sensor, or by imaging. Other conditions, such as effacement, cervical dilatation, and cervical position may also be monitored in a similar manner.
