Patent ID: 8386026

Claim:
A system for processing abdominal EMG signals, comprising: a signal processing module having an internal processing circuit; a plurality of pairs of skin impedance electrodes communicably coupled to the signal processing module and configured to acquire and transmit a raw abdominal EMG signal from a patient to the internal processing circuit where the raw abdominal EMG signal is amplified and filtered to a frequency band between about 20 Hz and about 150 Hz, thereby obtaining a processed abdominal EMG signal, wherein said skin impedance electrodes further comprise a skin-to-electrode impedance matching system for monitoring a plurality of skin-to-electrode impedances and altering the input impedance of said processing circuit to adapt to said skin-to-electrode impedances; an analog to digital converter operatively coupled to the processing circuit and configured to convert the processed abdominal EMG signal into a digital abdominal EMG signal; and a computer communicably coupled to the signal processing module and configured to receive and process the digital abdominal EMG signal into a viewable signal representative of abdominal activity, whereby an intensity of abdominal activity can be evaluated alongside a uterine EMG signal.
