Abstract
Abstract An electrode for an electrocardiograph comprising a reinforced base sheet having the underside thereof coated with a pressuresensitive adhesive and protected by a thin layer of removable paper. A snap fastener comprising a male and female portion extends through the center of the base sheet with the male portion of the snap fastener being firmly attached to the base sheet. The contacting surfaces of the male and female portion of the snap fastener are provided with a plurality of alternating grooves and ridges to increase the contact area and to prevent relative rotation of the respective male and female portions. A screen or sponge is attached to the underside of the male portion of the fastener and may be impregnated with an electrically conductive jelly. The female portion of the fastener is mounted into a housing designed for easy gripping with the fingers. The male and female portion and the housing have central openings defining a passage for receiving a syringe needle for flow of a conductive jelly and a ball check valve is preferably provided.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
182 words
An electrode adapted for use with an electrocardiograph and adapted to be attached to a body, comprising: attaching means adapted to be attached to a surface portion of the body, said attaching means including porous means adapted to engage the body, first conductive snap fastener means connected to said attaching means at said porous means second conductive snap fastener means fastened to said first conductive snap fastener means, said first and second means including first and second mating portions snapped together and electrically connected, means for electrically connecting said second means to an electrocardiograph, means defining a first opening in said first mating portion, means defining a second opening in said second portion and disposed in alignment with said first opening, said first and second openings forming a passage for supply of a conductive jelly therethrough and directly into contact with said surface portion of the body via said porous means when the electrode is attached to the body and connected to said electrocardiograph, and means in said electrically connecting means defining an opening for access to said first and second openings.
Claim 2
Dependent Claim
182 words
An electrode adapted for use with an electrocardiograph and adapted to be attached to a body, comprising: attaching means adapted to be attached to a surface portion of the body, said attaching means including porous means adapted to engage the body, first conductive snap fastener means connected to said attaching means at said porous means second conductive snap fastener means fastened to said first conductive snap fastener means, said first and second means including first and second mating portions snapped together and electrically connected, means for electrically connecting said second means to an electrocardiograph, means defining a first opening in said first mating portion, means defining a second opening in said second portion and disposed in alignment with said first opening, said first and second openings forming a passage for supply of a conductive jelly therethrough and directly into contact with said surface portion of the body via said porous means when the electrode is attached to the body and connected to said electrocardiograph, and means in said electrically connecting means defining an opening for access to said first and second openings.
Claim 3
Dependent Claim
36 words
The structure of claim 1 wherein said first and second mating portions are male and female snap fastener portions and wherein said openings are through the center portions of said female and male snap fastener portions.
Claim 4
Dependent Claim
21 words
The structure of claim 1 further including check valve means associated with said passage for preventing reverse flow of the jelly.
Claim 5
Dependent Claim
28 words
The structure of claim 3 wherein said check valve means comprises a ball having a diameter greater than the end of said passage closest to said porous means.
Claim 6
Dependent Claim
24 words
The structure of claim 4 wherein said porous means limits movement of said ball toward said surface portion while permitting flow of jelly therethrough.
Claim 7
Dependent Claim
12 words
The structure of claim 5 wherein said porous means comprises a screen.
Claim 8
Dependent Claim
13 words
The structure of claim 5 wherein said porous means comprises a sponge pad.
