<p>A one-chip signal processor receives heart beat signals of a foetus and maternal labour pain intensity signals. A data processor statistically processes the correlation between the labour pain intensity signals and the heart rate, a printing unit being for recording the processed correlation on paper. An alarm unit produces an output in three stages, i.e. normal, caution and alarm based upon the heart beat signals. The labour pain intensity signals are transmitted to a remote monitoring apparatus.</p> |
