  • Patent number: 5632274
    Abstract: A connector attached to an end of a twisted wire pair, whose other end has fetal and maternal electrodes. A driving tube is removed from the twisted wire pair by pulling a drive handle and driving tube over the connector. The outer diameter of the connector is smaller than the inner diameter of the driving tube. After the connector is free, it is inserted into a housing of a leg plate, which electrically interconnects terminals of the connector and thereby the electrodes with a remote monitoring device. The housing has finger grips to help hold the housing during the insertion of the connector. The leg plate also has a base which is held in position against a mother's leg and has a ground electrode which is also electrically interconnected with the device. The housing is rotatable relative to the base.

  • Patent number: 5205288
    Abstract: A female fetal electrode product includes a socket connector electrically connected to fetal and maternal electrodes. The female connector shrouds and electrically connects with a male plug connector. The electrodes may be electrically connected with a remote monitoring device via the male and female connectors. The male connector may extend within an opening in the leg plate or project from the leg plate and may be removable from the leg plate. The female socket connector has an outer dimension less than the inner dimension of a driving tube so that the driving tube can be pulled over the female socket connector after the fetal electrode has been attached to a fetus.

  • Patent number: 5168876
    Abstract: A connector device interposed between a fetal heart rate monitor and fetal and material electrodes. The device includes a connector inserted in a leg plate. The leg plate has a housing which contains a printed circuit board. The board or housing is detachably connected to a base. The board has tracers which interconnect output terminals of the housing with input contacts of the housing and with a ground electrode of the base. The output terminals lead to the fetal heart rate monitor. The input contacts are in electrical contact with terminals of the connector, which in turn are electrically connected with the electrodes via a twisted wire pair. The input contacts of the leg plate are preferably in the form of barrel contacts which have fingers whose free ends either electrically connect with the connector terminals or engage with a recess on an exterior periphery of the connector.
