Abstract

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. 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.

Description

Technical field: [0001] The present invention relates to the measurement of the electrical activity of the body. More specifically, the invention relates to measurements and their analysis to predict the state of a body part. Background technique: [0002] There is currently no objective way to evaluate uterine contractions. This is true in nonpregnant patients with severe contractions associated with dysmenorrhea, or in pregnant patients in whom the uterus sometimes moves before labor. Usually, the uterus is quiescent in nonpregnant women and during most pregnancies. At the end of pregnancy, however, the myometrium is subjected to a series of changes that result in simultaneous, rhythmic uterine contractions (labor). The diagnosis of childbirth is a very important issue facing obstetricians. In addition, preterm labor occurs in approximately 10% of pregnant patients and is difficult to diagnose. On-due or premature labor often requires adjunctive drug therapy to stimul...
