Continuous measurement of cervical dilatation during labour
An instrument for the continuous measurement of cervical dilatation is described. The principle of operation, being that of mutual inductance, utilises two coils, one on the posterior lip of the cervix and the other on the anterior, the axes of these coils being kept parallel by a flexible linkage. …
