CervoCheck Device to Prevent Preterm Labor

Jul 27, 2010
Premature delivery has always been associated with numerous health risks for a baby. To deal with this problem, students from the Johns Hopkins University have developed a novel device to detect the early signs of preterm labor and help to prevent it.

Babies born before 37 gestational weeks are considered to be premature and need special attention from the doctors. Premature delivery often happens with the increasing number of multiple births, which often result from fertility treatments. Women, who decide to have a baby later in life are also at increased risk of complications, such as preterm labor.

The new device called CervoCheck consists of the cervical ring made of medical grade biocompatible silicone elastomer with the sensors that is inserted inside the vagina. The sensors identify electrical signals that are linked to the contractions of the uterus. This allows predicting premature delivery at an early stage and helping doctors prevent labor by up to six or more weeks, which can play an important role for baby's health.

Until now, specialists use a tocodynamometer, a tool made to sense uterine contractions externally, but it can be too late to prevent premature delivery.
The new device is used internally and will be more effective at detecting early signs of labor.
