Abstract
Abstract An electrode assembly for use in electric field therapy apparatus comprises arranging between a pair of opposed electrodes an appropriate number of auxiliary electrodes with a certain distance interposed therebetween and containing all of these electrodes thus arranged in an insulating material, and enables electric field to be applied to a desired sick part of human body to be treated by selectively using pairs of these electrodes and effective electric field therapy to be attained due to the presence of the auxiliary electrodes which serve to prevent the electric field from being diffused.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
An electric field therapy apparatus comprising electrode means and a high voltage source, said electrode means including an insulating member on which the body of a patient being treated is received, and a plurality of elongate electrical conductors incorporated in said insulating member and extending transversely to the longitudinal axis of said member, said conductors being spaced apart in serial relationship along the longitudinal axis of said insulating member and being insulated from one another by the insulation of said insulating member, and said apparatus further comprising means for selectively connecting said conductors at least two at a time to said high voltage source such that an electric field is produced between the two connected conductors and the unconnected conductor or conductors located between the at least two connected conductors serve to confine the electric field to an area between the at least two connected conductors.
Claim 2
Dependent Claim
146 words
An electric field therapy apparatus comprising electrode means and a high voltage source, said electrode means including an insulating member on which the body of a patient being treated is received, and a plurality of elongate electrical conductors incorporated in said insulating member and extending transversely to the longitudinal axis of said member, said conductors being spaced apart in serial relationship along the longitudinal axis of said insulating member and being insulated from one another by the insulation of said insulating member, and said apparatus further comprising means for selectively connecting said conductors at least two at a time to said high voltage source such that an electric field is produced between the two connected conductors and the unconnected conductor or conductors located between the at least two connected conductors serve to confine the electric field to an area between the at least two connected conductors.
Claim 3
Dependent Claim
156 words
An electric field therapy apparatus designed to produce an electric field for the treatment of a patient, said apparatus comprising electrode means and a high voltage source, said electrode means including an insulating member on which the body of a patient being treated is received, and a plurality of electrically conductive electrodes incorporated in said insulating member, said electrodes being spaced apart in serial relationship along the longitudinal axis of said insulating member and being insulated from one another by the insulation of said insulating member, and said apparatus further comprising means for connecting spaced ones of said electrodes to said high voltage source two at a time so that at least one unconnected electrode is located between the two connected electrodes such that an electric field is produced between the two connected electrodes and the at least one unconnected electrode serves to confine the electricl field to an area between the said two connected electrodes.
Claim 4
Dependent Claim
156 words
