Apparatus that provides accurate readings and measurements of the dilation of an expectant mothers cervix during pregnancy—during and/or before the onset of labor. The apparatus envisioned by the present invention includes a speculum, control panel, prongs used to make contact with the birth canal walls, a tensile device which may be used to calculate the cervical dilation, a video camera and light source for viewing within the birth canal. The accuracy of measurements obtained by the apparatus properly indicate the expectant mothers progression of labor. Monitors may also be used in conjunction with the apparatus for viewing and measuring the cervical dilation. Additionally, processors may also be used to assist in further analysis and cervical dilation measurement.
