Electrode assemblies
First Claim
1. An electrode assembly for use in an electrocardiographic test wherein electrodes must be quickly and accurately positioned on a patient, said assembly comprising:
- (a) an electrode;
(b) an underlying non-conductive pad permanently secured to the electrode; and
(c) an overlying plastic sheet having an approximately centered area and having circumjacent peripheral areas, further said overlying plastic sheet being permanently secured in its approximately centered area to the electrode and the circumjacent peripheral areas of said plastic sheet are unattached for sliding movement.

Abstract
Electrode assemblies are particularly used with a precordial overlay to obtain a quick and accurate positioning of electrodes for an electrocardiographic test. Each electrode assembly comprises an electrode to receive a lead wire, an underlying non-conductive pad secured to the electrode, and an overlying plastic sheet secured to the electrode in a manner whereby its peripheral areas are unattached. Preferably, the electrode assembly also has an underlying adhesive layer secured to the non-conductive pad and a removable backing strip. The precordial overlay has a set of slots in which the electrode assemblies are slidably mounted. The underlying non-conductive pad and the overlying plastic sheet of the assemblies effectively trap the electrode assemblies in the slots to allow sliding electrode movement. The sliding movement of the electrodes allows for limited but quick movement from an approximate chest area location to a precise chest area location for a reliable electrocardiographic test.

9. An electrode assembly for use in an electrocardiographic test wherein electrodes must be quickly and accurately positioned on a patient, said assembly comprising:
-
(a) an electrode having a conductive metal post and conductive plate with a foam disk secured to an underside of the conductive plate, further said foam disk substantially saturated with a conducting gel; (b) an underlying non-conductive foam pad permanently secured to the electrode, said foam pad further having an approximately centered cut-out to receive the foam disk of the electrode; (c) an overlying plastic sheet fixed in an approximately centered area to the conductive metal post and conductive plate whereby peripheral areas of said plastic sheet are unattached; (d) an adhesive layer on the underside of the non-conductive foam pad; and (e) a removable backing strip on the adhesive layer to protect said adhesive layer during shipping or storage of the electrode assembly. - View Dependent Claims (10, 11, 12)

13. A one-piece electrode assembly for use with a precordial overlay wherein the overlay has a set of discreet cut-outs to receive electrodes and to allow the electrodes to be slidably positioned on a patient, said assembly comprising:
-
(a) an electrode; (b) an underlying non-conductive pad secured to the electrode; and (c) an overlying plastic sheet having an approximately centered area and having peripheral areas circumjacent the approximately centered area and further said overlying plastic sheet is secured in its approximately centered area to the electrode and the peripheral areas of said plastic sheet are unattached to the underlying non-conductive pad, whereby the underlying non-conductive pad and the overlying plastic sheet allow the electrode assembly to be positioned in one of the discreet cut-outs of the precordial overlay in a manner wherein the electrode is trapped in the discreet cut-out with limited electrode sliding movement within said discreet cut-out. - View Dependent Claims (14, 15, 16, 17, 18, 19)
