Abstract

A system for measuring cervical dilation of a woman's uterus during a first stage of labor comprising an expandable grasping device having two oppositely facing grasping members configured such that The grasping device grasps the dilated cervix. The system also includes a first elongated element having a calibration scale disposed thereon, and a second elongated element. The second elongated portion has an indicator disposed thereon. The first and second elongated elements are mechanically connected to the grasping device in such a way that when the grasping device is expanded with a dilated cervix, the first and second elongated elements Relative linear motion is created between the second elongate members, thereby moving the indicator relative to the calibrated scale to give a measure of cervical dilation.

Description

technical field [0001] The invention relates to a medical device, in particular to a cervical dilation monitor. Background technique [0002] As an introduction, it remains standard practice among obstetricians to assess the progress of labor during the first stages of active labor by performing a routine vaginal examination to estimate cervical dilation. At this stage of labor, the cervix dilates to about 10 cm and effaces into a very thin layer. However, these examinations are uncomfortable for the patient, imprecise, objective and risk introducing infectious diseases into the uterus, disadvantages that are amplified if consecutive examinations are performed by different observers. [0003] Related to the present invention is US Patent No. 5,658,295 to Krementsov, which relates to a caliper-like instrument having graduations for indicating dilation. The device to which Krementsov relates was not designed to remain in place for continuous monitoring. In addition, the dev...
