Patent ID: 8313447

Claim:
A method for monitoring for complications of pregnancy, comprising: fitting a belt around the abdomen of a pregnant human for at least 12 hours a day, said belt containing at least one uterine contraction sensor configured to monitor uterine contractions and produce uterine contraction signals; said belt containing at least one ambient motion sensor configured to monitor non-uterine contraction movements and produce other movement signals; using a first processor to correct said uterine contraction signals for distortion caused by said other movement signals, thus producing corrected uterine contraction signals; wirelessly transmitting said corrected uterine contraction signals to a wireless pregnancy monitoring device; wirelessly receiving said corrected uterine contraction signals; using a second processor to analyze said corrected uterine contraction signals for a complication of pregnancy; and producing a warning message when a complication of pregnancy is detected.
