Patent ID: 7447542

Claim:
A system comprising: an electromyogram (EMG) system comprising at least one EMG sensor operative to sense electromyographic activity generated in a uterine muscle and output electrical muscular activity signals; at least one position sensor placed near said at least one EMG sensor; and a processor in communication with said EMG system and said at least one position sensor, said processor operative to process electrical muscular activity signals of said EMG system and three-dimensional positions of said at least one EMG sensor from said at least one position sensor to provide an output and display of said electrical muscular activity signals as sensed by said at least one EMG sensor and the three-dimensional positions of said at least one EMG sensor at the same time, and further comprising a cardiotocogram (CTG) monitor in communication with said processor, said CTG monitor comprising a fetal beat-to-beat heart rate (FHR) sensor and a uterine labor activity (TOCO) sensor, and wherein said system indicates onset of premature birth based on the three-dimensional positions of said at least one EMG sensor together with TOCO information from said TOCO sensor.
