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.

Connection arrangement for monitoring fetal heart rate

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 for use in monitoring fetal heart rate

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.

Connector device for use in monitoring fetal heart rate

Novel strip chart recorders and strip chart recording paper are provided which are cooperable so that the recorder detects the proximity of a terminal edge of the paper, so that the recorder can signal this occurrence to the user enabling him to insert a new supply of strip chart paper in the recorder to avoid the loss of data. The recorder also cooperates with the strip chart paper to determine when paper is absent from the recorder, for example, when it has been exhausted, thereupon to signal this further occurrence to the user and take steps to avoid damage to the recorder which can result through its operation in the absence of paper in the recorder mechanism.
