Abstract
Abstract A disposable medical electrode comprising a support member made of a closed cell plastic material having an adhesive surface. A centrally located contact element is embedded therein so as to leave an exposed portion thereof at the adhesive side of the support member. A smaller pad member made up of an open cell plastic material is adhered to the adhesive surface of the support member at a position opposite to and in contact with the exposed portion of the contact element. In use, the pad member has a conductive gel dispersed throughout so that when the electrode is placed against the skin of a patient a good conductive path is present from the skin through the gelled pad to the contact element.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A monitoring electrode comprising a substantially flat support member formed of plastic foam material having a closed cellular configuration throughout, one surface of which is adhesive; a contact element embedded in said support member, a first contact portion thereof being exposed at said one surface and a second contact portion thereof protruding from the opposite surface of said support member; a pad member formed of plastic foam material having an open cellular configuration adhered to said adhesive surface of said support member at a position such that the inner surface of said pad member is in contact with and substantially covers said exposed portion of said contact element, the outer surface thereof being capable of contacting a surface to be monitored.
Claim 2
Dependent Claim
121 words
A monitoring electrode comprising a substantially flat support member formed of plastic foam material having a closed cellular configuration throughout, one surface of which is adhesive; a contact element embedded in said support member, a first contact portion thereof being exposed at said one surface and a second contact portion thereof protruding from the opposite surface of said support member; a pad member formed of plastic foam material having an open cellular configuration adhered to said adhesive surface of said support member at a position such that the inner surface of said pad member is in contact with and substantially covers said exposed portion of said contact element, the outer surface thereof being capable of contacting a surface to be monitored.
Claim 3
Dependent Claim
45 words
