US Patent:

6363271, Mar 26, 2002

Filed:

Nov 1, 2000

Appl. No.:

09/702616

Inventors:

Daniel K. Berry - Brooks AFB TX 78235-1015

International Classification:

A61B 505

US Classification:

600361, 600345, 600304

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 patients 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.

Abstract:

A device for implantation on the cervix of a pregnant female that provides an alerting means by which a female patient or her health caregiver is notified of the onset of labor. The device comprises a housing manufactured from biocompatible material into which a spindle member joined to a tension sensor passes. The housing also contains a transmitter and a power source for the sensor and transmitter. A plurality of sutures are fixed the spindle and pass out of housing so that they may be attached to the female patients cervix. A tension knob is provided for winding excess suture length onto the spindle, thereby securing the device within the vagina. Dilatation of the cervix at the onset of labor exerts tension on the sutures which is conveyed to the spindle and translated by the sensor to a signal directed at 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 of impending birth.

Abstract:

A device for implantation on the cervix of a pregnant female that provides monitoring means by which the dilatation of a female patients cervix may be monitored during the first phase of labor. The device comprises a housing manufactured from biocompatible material into which a spindle member joined to a tension sensor passes. The housing also contains a transmitter and a power source for the sensor and transmitter. A plurality of sutures are fixed the spindle and pass out of housing so that they may be attached to the female patients cervix. A tension knob is provided for winding excess suture length onto the spindle, thereby securing the device within the vagina. Dilatation of the cervix at the onset of labor exerts tension on the sutures which is conveyed to the spindle and translated by the sensor to a signal directed at the transmitter. Throughout the first phase of labor, the transmitter issues electronic signals to a second electronic device such as a computer, allowing the compilation and display of dilatation data.
