ABSTRACT:
A dual element electrical connector for body contact has a flexible base with first and second electrodes secured thereto. A cover secured to the base has an aperture which exposes the electrodes. A sponge pad overlies the electrodes and is impregnated with a conductive gel. The cover is secured to the patient, compressing the sponge pad against him for good body contact. A cable and connection circuit couple the first and second electrodes to an electrical treatment apparatus having two terminals each providing or receiving a similar voltage (or ground) to or from the first and second electrodes. The cable and connection circuit are so constructed that if the treatment apparatus is provided with a device to sense the conductivity between the two terminals and the cable becomes disconnected from either the treatment apparatus or the dual element electrical connector, that condition can be detected. The cable is provided with a switch to actuate a test circuit to check the integrity of the electrical circuit from the terminals to the electrodes. The test circuit includes a variable resistor to match the conductivity of the gel with the treatment apparatus.
