Electrode interface system
First Claim
1. An interface system for interfacing an electrode with a maternal-fetal monitor, wherein the maternal-fetal monitor has a port configured to operably connect with a tocodynamometer to receive output from the tocodynamometer or to connect with an intrauterine pressure catheter to receive output from the intrauterine pressure catheter, and wherein the maternal fetal monitor is configured to display the tocodynarnometer output or the intrauterine pressure catheter output to a user, wherein the interface system comprises:
- a first component comprising;
an electrode interface configured to operably and removably connect with the electrode and to receive an electrohysterogram signal from the electrode; and
a wireless signal transmitter configured to receive the electrohysterogram signal from the electrode interface when the electrode interface is connected with the electrode and to wirelessly transmit the received electrohysterogram signal to a wireless signal receiver located remote from the first component; and
a second component comprising;
the wireless signal receiver configured to receive the electrohysterogram signal transmitted by the wireless signal transmitter;
a signal converter configured to receive the electrohysterogram signal from the wireless signal receiver and to process the electrohysterogram signal into output data that mimics electrical output from a tocodynamometer or an intrauterine pressure catheter; and
a maternal-fetal monitor port interface configured to operably and removably connect to the port of the maternal-fetal monitor, wherein the maternal-fetal monitor port interface is configured to receive from the signal converter the output data that mimics electrical output from a tocodynamometer or an intrauterine pressure catheter and to communicate to the maternal-fetal monitor the output data that mimics electrical output from a tocodynamometer or an intrauterine pressure catheter when the maternal-fetal monitor port interface is connected to the port of the maternal-fetal monitor.

Abstract
An electrode interface system for providing a connection between at least one electrode and a maternal-fetal monitor, wherein the interface system converts electrical muscle activity captured by the electrode(s) into uterine activity data signals for use by the maternal-fetal monitor. The electrode interface system of the invention preferably includes a signal converter for processing the signals from the electrode(s) into signals similar to those produced by a tocodynometer.
