ABSTRACT:
An extra-uterine sensing device for directly measuring changes in pressure brought about by uterine contractions of a wearer. The sensing device includes an outer member adapted for fixed attachment to the abdomen in an area of the wearer's uterus to establish a minimum pre-load and a sensor unit positioned between the outer member of the abdomen. The sensor unit includes a variable resistor formed of a pressure sensitive ink, a first electrically conductive member interfacing with the ink and a second electrically conductive member interfacing with the ink and spaced from the first electrically conductive member and a device attached to the first and second electrically conductive members to monitor changes in the electrical resistance. Also disclosed is an extra-uterine method of sensing uterine contractions of a wearer having a fundus including attaching a sensing device of the type described to the abdomen in the area of the wearer's uterus creating a minimum pre-load on the sensing device sufficient to establish the reference level for instantaneously detecting changes in pressure caused by contractions, non-mechanically and directly converting a change in pressure to a change in electrical resistance and converting the change in resistance to a non-decaying electrical signal and monitoring the electrical signal.
