Abstract
Abstract A single piece electrocardiograph receiver including a pair of electrodes having pieces of spongy porous material associated therewith and mounted at opposite ends of a handle so as to be in a fixedly spaced orientation. The spongy material absorbs a conductive material, such as water, and the receiver can then be pressed against the side of an animal in a heart spanning orientation to receive the electric impulses from the heart.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
An electrocardigraph receiver for receiving electric impulses produced by the heart muscle of an animal, said receiver comprising: a first and second electrode means each including an electrode and resilient porous sponge means adapted to absorb an electrically conducting liquid and positioned for completing electrical contact between the associated electrode and an animal's body when the electrode means is pressed thereagainst, said electrode means each further including a housing having the associated electrode fixedly engaged therein with the porous means maintained in proximity to the electrode and extending externally of said housing for providing contact with the animal's body; means mechanically connecting said first and second electrode means and fixedly positioning said electrode means in spaced apart relationship a distance at least as great as the span of the animal's heart muscle, said mechanical means including an elongated, semi-flexible tubular member having a housing of each electrode means affixed to each end thereof and forming a handle for pressing said first and second electrode means against the body of the animal; and means for electrically coupling the electrodes of said electrode means to an electrocardiograph.
Claim 2
Dependent Claim
185 words
An electrocardigraph receiver for receiving electric impulses produced by the heart muscle of an animal, said receiver comprising: a first and second electrode means each including an electrode and resilient porous sponge means adapted to absorb an electrically conducting liquid and positioned for completing electrical contact between the associated electrode and an animal's body when the electrode means is pressed thereagainst, said electrode means each further including a housing having the associated electrode fixedly engaged therein with the porous means maintained in proximity to the electrode and extending externally of said housing for providing contact with the animal's body; means mechanically connecting said first and second electrode means and fixedly positioning said electrode means in spaced apart relationship a distance at least as great as the span of the animal's heart muscle, said mechanical means including an elongated, semi-flexible tubular member having a housing of each electrode means affixed to each end thereof and forming a handle for pressing said first and second electrode means against the body of the animal; and means for electrically coupling the electrodes of said electrode means to an electrocardiograph.
Claim 3
Dependent Claim
57 words
An electrocardiograph receiver as claimed in claim 1 wherein the means electrically coupling the electrodes includes insulated wire extending through the tubular member, the tubular member is formed with at least an external portion thereof being electrically conducting, and a grounding connection for the electrocardiograph being electrically connected to the electrically conducting portion of the tubular member.
Claim 4
Dependent Claim
32 words
An electrocardiograph receiver as claimed in claim 1 wherein each of the sponge means is removeably fixed in proximity to the associated electrode by flexible fingers projecting inwardly into the sponge means.
