SYSTEM FOR DETECTION AND ANALYSIS OF MATERIAL UTERINE, MATERNAL AND FETAL CARDIAC AND FETAL BRAIN ACTIVITY

摘要

The present invention presents a method and apparatus for recording and analyzing uterine electrical activity, or electromyography (EMG), from the surface of the abdomen, vagina, or cervix of a patient for the purpose of diagnosing contractile patterns of the uterus in pregnant and non-pregnant women, as well as for monitoring maternal and fetal ECG and fetal brain activity. The method and apparatus described include methods for the systematic detection, analysis, characterization and communication of infomation about electrical signals recorded from the abdominal/vaginal/cervical surface. The present invention provides data analysis techniques for analyzing the electrical data measured from the surface of a patient to characterize their uterine, abdominal, and cardiac muscle activity, as well as cardiac and brain activity of the fetus simultaneously or separately. These techniques and apparatus are appropriate for use in a clinic or through landline or wireless communication for use as a remote or home uterine/fetal monitoring system.
