Abstract
Abstract A monitoring electrode for attachment to a patient for use with electronic medical diagnostic and monitoring equipment has a laminate construction including a foam pad, a conductor carrier strip having a metallized conductor thereon adjacent to the foam pad, the conductor carrier and a portion of the foam pad being covered by a conductive film, also applied to the foam pad in the form of a strip. The surface of the foam pad and the exposed portion of the conductive film strip to be attached to the patient are covered with an adhesive layer. The foam strip has a recess in the periphery thereof forming a tab onto which the metallized conductor extends, to which a lead of the diagnostic equipment can be attached, such as by a clip.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
An electrode attachable to a patient for use with electronic medical monitoring or diagnostic equipment, said electrode comprising: a foam pad; a non-conductive carrier attached to one side of said of said foam pad having a conductive metallized strip thereon at a side of said carrier facing away from said foam pad; a conductive film strip overlying at least said conductive metallized strip, said conductive film strip extending beyond said conductive metallized strip on each side thereof and covering said carrier and a portion of said foam pad; an adhesive layer covering said side of said foam pad on which said non-conductive carrier is attached and also covering said conductive film strip; and a means for electrically connecting said conductive metallized strip to a lead of said diagnostic or monitoring equipment.
Claim 2
Dependent Claim
131 words
An electrode attachable to a patient for use with electronic medical monitoring or diagnostic equipment, said electrode comprising: a foam pad; a non-conductive carrier attached to one side of said of said foam pad having a conductive metallized strip thereon at a side of said carrier facing away from said foam pad; a conductive film strip overlying at least said conductive metallized strip, said conductive film strip extending beyond said conductive metallized strip on each side thereof and covering said carrier and a portion of said foam pad; an adhesive layer covering said side of said foam pad on which said non-conductive carrier is attached and also covering said conductive film strip; and a means for electrically connecting said conductive metallized strip to a lead of said diagnostic or monitoring equipment.
Claim 3
Dependent Claim
49 words
An electrode as claimed in claim 1 wherein said means for connecting said conductive metallized strip to said lead is a tab formed in a recess at a periphery of said foam pad onto which said conductive metallized strip extends, said conductive metallized strip being exposed on said tab.
Claim 4
Dependent Claim
17 words
An electrode as claimed in claim 1 wherein said non-conductive carrier extends beyond the conductive metallized strip.
Claim 5
Dependent Claim
116 words
An electrode for attachment to a patient for use with medical diagnostic equipment, said electrode comprising: a flexible backing layer; a non-conductive carrier layer having one side thereof adjacent said backing layer and having a conductor layer on an opposite side thereof; a conductive film layer overlying at least said conductor layer, said conductive film layer extending beyond said conductor layer on each side thereof and covering said carrier layer and a portion of said backing layer; an adhesive layer overlying said conductive film layer and a side of said backing layer to which said carrier layer is adjacent; and a means for electrically connecting said conductor layer to a lead of said medical diagnostic equipment.
Claim 6
Dependent Claim
116 words
An electrode for attachment to a patient for use with medical diagnostic equipment, said electrode comprising: a flexible backing layer; a non-conductive carrier layer having one side thereof adjacent said backing layer and having a conductor layer on an opposite side thereof; a conductive film layer overlying at least said conductor layer, said conductive film layer extending beyond said conductor layer on each side thereof and covering said carrier layer and a portion of said backing layer; an adhesive layer overlying said conductive film layer and a side of said backing layer to which said carrier layer is adjacent; and a means for electrically connecting said conductor layer to a lead of said medical diagnostic equipment.
Claim 7
Dependent Claim
19 words
An electrode as claimed in claim 4 wherein said non-conductive carrier layer is in the form of a strip.
Claim 8
Dependent Claim
18 words
An electrode as claimed in claim 4 wherein said conductor layer is in the form of a strip.
Claim 9
Dependent Claim
19 words
An electrode as claimed in claim 4 wherein said conductive film layer is in the form of a strip.
Claim 10
Dependent Claim
52 words
An electrode as claimed in claim 4 wherein said means for electrically connecting said conductor layer to a lead of said medical diagnostic equipment is a tab formed in a recess at a periphery of said backing layer onto which said conductor layer extends, said conductor layer being exposed on said tab.
Claim 11
Dependent Claim
17 words
An electrode as claimed in claim 4 wherein the nonconductive carrier layer extends beyond the conductor layer.
