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.

Fetal electrode product with female socket connector and connector

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.
