Abstract
Abstract An improved cup-shaped electrode with holes therethrough to allow both ingress of electrically conductive paste and egress of entrapped air, and with a vertical partition mounted between the holes within the electrode cavity to both guide the flow of paste and air in the cavity and to prevent possible interferences therewith by a surface of the human body with which the electrode is in contact. In certain illustrative embodiments, egress holes number more than one, and vertical partitions may number more than one to improve the efficiency of the electrode.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
In an improved electrocardiographic-type electrode, which utilizes electrically conductive paste to assure good electrical contact with a surface of a human body, and including an electrode cup having a rim to accommodate a washer adapted to make physical contact with the body, there being a plurality of holes formed through the cup, the improvement comprising: electrically nonconductive partition means having substantially vertical ends and being substantially vertically mounted within said cup between said holes for guiding both ingress of said paste and egress of entrapped air and for preventing said human surface from inhibiting paste ingression and air egression.
Claim 2
Dependent Claim
99 words

Claim 3
Dependent Claim
45 words
An electrode as set forth in claim 1 wherein: said holes are two in number and are arranged about said partition means so that a line joining substantially the centers of said holes intersects said partition means substantially equidistant from eiTher of said vertical ends.
Claim 4
Dependent Claim
22 words
An electrode as set forth in claim 2 wherein: a. said partition means terminates in a plane defined by a circular rim.
Claim 5
Dependent Claim
21 words
An electrode as set forth in claim 2 wherein: said partition means is mounted approximately equidistant from either of said holes.
Claim 6
Dependent Claim
27 words
An electrode as set forth in claim 1 wherein: a. said partition means is mounted between a single entrance hole and a plurality of smaller exit holes.
Claim 7
Dependent Claim
34 words
An electrodes set forth in claim 1 wherein: a. said partitions means is comprised of a plurality of segments, said segments together cooperating to provide tortuous flow paths between the ingress and egress holes.
