The present invention relates to a method and instrumentation for detecting the changes in cervical connective tissues associated with cervical dilation or effacement. 7 his method uses an optical system to determine changes by laser or other light (12) induced native fluorescence spectroscopies (LIF) of cervix. The method is non-invasive and instant. It operates by shining excitation light (17) of a selected wavelength on cervical tissue and measuring fluorescent emissions. The measurement is completed in seconds. This method is an excellent fit with the clinical needs for determining the status of cervical dilation.

Procédé et instrument permettant de détecter les modifications des tissus connectifs cervicaux associés à la dilatation ou à l'effacement du col de l'utérus. Ce procédé utilise un système optique pour déterminer les modifications du col de l'utérus par spectroscopie laser ou d'autres spectroscopies par fluorescence naturelle induite par de la lumière (12). Ce procédé est non invasif et instantané; il consiste à éclairer les tissus cervicaux avec de la lumière d'excitation (17) d'une longueur d'onde sélectionnée puis à mesurer les émissions fluorescentes, cette mesure s'effectuant en quelques secondes. Ce procédé correspond très bien aux besoins cliniques pour déterminer l'état de la dilatation du col de l'utérus.
