Abstract
Abstract A disposable ground plate electrode for effecting a connection of electromedical equipment to the body of a patient by surface contact, particularly with the aid of a conductive gel, in which the conductive surface of the ground plate is provided with a series of ridges preferably concentric, which are adapted to engage such a body surface and are of a size and shape insufficient to cause discomfort but sufficient to form retaining means for a conductive gel disposed thereon to localize spreading of such a gel, resulting from relative movement between such a body surface and the ground plate.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
169 words
A disposable ground plate electrode for effecting a connection of electromedical equipment to the body of a patient by surface contact usually by resting thereupon, particularly with the aid of a conductive gel, comprising a normally planar base member of suitable sheet stock having a top face formed by a conductive layer carried thereby, said conductive layer having a plurality of outwardly extending relatively narrow elongated ridges formed thereon in a symmetrical pattern and covering a major portion of said top face and adapted to engage the skin surface of such a body, said ridges projecting beyond the surface of such conductive layer a distance sufficient to form a plurality of collection abutments for a conductive gel disposed on such sheet, the abutments being angled inwardly with respect to the central portion of the electrode, whereby outward spreading of such gel on said sheet as a result of relative movement between such sheet and the skin surface of such a body is localized and thereby retained on such sheet.
Claim 2
Dependent Claim
169 words
A disposable ground plate electrode for effecting a connection of electromedical equipment to the body of a patient by surface contact usually by resting thereupon, particularly with the aid of a conductive gel, comprising a normally planar base member of suitable sheet stock having a top face formed by a conductive layer carried thereby, said conductive layer having a plurality of outwardly extending relatively narrow elongated ridges formed thereon in a symmetrical pattern and covering a major portion of said top face and adapted to engage the skin surface of such a body, said ridges projecting beyond the surface of such conductive layer a distance sufficient to form a plurality of collection abutments for a conductive gel disposed on such sheet, the abutments being angled inwardly with respect to the central portion of the electrode, whereby outward spreading of such gel on said sheet as a result of relative movement between such sheet and the skin surface of such a body is localized and thereby retained on such sheet.
Claim 3
Dependent Claim
17 words
A disposable ground electrode according to claim 1, wherein said pattern comprises a plurality of concentric circles.
Claim 4
Dependent Claim
78 words
A disposable ground plate electrode according to claim 2, wherein said base member is provided with a fold line adjacent at least one edge thereof, defining a peripheral strip which may be folded back upon the base member with the conductive face of the strip outermost to provide two exposed oppositely disposed conductive surfaces along such fold line for engagement with opposed portions of clamping means carried by a conductor lead to be electrically connected to such surface.
Claim 5
Dependent Claim
23 words
A disposable ground plate electrode according to claim 3, wherein said sheet is provided with respective fold lines adjacent oppositely disposed edges thereof.
