Abstract: A disposable electrode assembly is comprised of a thin flexible foam pad of insulating material having an adhesive base which can be firmly secured to a patient. The base carries an electrode which is in electrical contact with the patient's skin when the assembly is secured to the patient. A plurality of input terminal connectors are carried by the pad and are adapted to be connected to a plurality of electrodes which may be applied to the scalp of a fetus or to other parts of a patient's body. Also carried by the pad is an output connector which, through a cable, is adapted to connect the electrode assembly to a fetal monitor or an electrocardiograph or similar device. The output connector is electrically connected to the input connectors and to the base electrode by conductors within the electrode assembly.
