Abstract
A device for implantation on the cervix of a pregnant female that provides a means by which a female patient or her health caregiver is notified of the rupture of membranes by the release of amniotic fluid. The device comprises a housing manufactured from biocompatible material having a hole through which amniotic fluid in the patient's vagina may pass. The housing contains a pH meter and a transmitter in electronic communication therewith as well as a power source for the sensor and transmitter. When amniotic fluid is released through the cervix into the vagina, a quantity thereof may pass into the housing and sensed by the sensor, causing the sensor to direct a signal to the transmitter. The transmitter issues an electronic signal to a second electronic device such as a pager or PDA, notifying the patient or her health caregiver that her water has broken.
