Abstract
A cervical dilation reading apparatus and method of use to accurately and precisely determine cervical dilation measurements during labor and delivery. The apparatus includes a measuring device having a length with a first end and a second end, a fixed attachment configured to couple with a first finger and fixedly engage the first end of the measuring device, and a slidable attachment configured to couple with a second finger and slidably engage the measuring device along the length between the first and second ends. The method includes providing a cervical dilation reading apparatus, inserting the first and second fingers into the vaginal introitus and locating the cervix and cervical os, placing the first finger on a first side of the cervical os and extending the second finger away from the first finger to a second side, opposite the first side, of the cervical os, thereby extending the length of the measuring device between the first and second fingers to a substantially extended state, removing the first and second fingers, and determining a diameter of the cervical os by the length of the measuring device in the substantially extended state between the fixed attachment and s…
