Abstract

A fetal electrode assembly for use in monitoring fetal heart rate and used in conjunction with a fetal monitor coupling device supported on the mother's body. The assembly including fetal and maternal electrodes secured to an insulating holder, a connector dimensioned and shaped to be received in an opening in a coupling device housing and having first and second contacts separated and electrically isolated from each other and positioned to make electrical contact with complementary contact members in the coupling device. An insulated pair of elongated flexible wires, each electrically connecting a respective one of the first and second contacts to a respective one of the fetal and maternal electrodes. An elongate tubular sheath covers the connector and has a first open end extending over and receiving the ends of the pair of flexible wires, the opposite end of the sheath being spaced from each of the electrodes. An elongated, flexible driving member for rotating the holder is displaceable relative to the wires in a direction away from the electrodes and a clamp is mounted on one end of the driving member and has a first position for engaging the wires to prevent relative movement between said wires and the driving member and a second position for releasing the wires to permit the driving member to be moved relative to the wires. A snap spring contact is mounted in the coupling device for engaging a snap convertor on an electrode.
