Abstract
Abstract The defibrillator pad of the present invention comprises a lower layer of electrically conductive tacky polymer and an upper layer of filamentous carbon fabric. The pad is placed on the patient's chest with the polymer layer facing downwardly in contact with the patient's chest and with the carbon layer facing upwardly for engagement with the electrodes of the defibrillator paddles.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
162 words
A method for preparing a patient's chest having an exposed skin surface for accepting a defibrillator paddle, said method comprising: taking a laminated defibrillator pad having a bottom layer of electrically conductive polymer which is tacky so as to adhere to most surfaces it contacts, said pad having an upper layer comprising fabric material formed from filamentous carbon, said upper layer being adhered to and in electrical contact with said bottom layer; placing said pad on said patient's chest with said bottom layer in contact with said exposed skin surface of said patient's chest whereby said tackiness of said bottom layer will cause said pad to be detachably adhered to and in electrical contact with said exposed skin surface of said patient's chest; and placing said defibrillator paddle in facing engagement with and in electrical contact with said upper layer of said pad whereby said pad will provide electrical continuity from said defibrillator paddle to said exposed skin surface of said patient.
Claim 2
Independent Claim
162 words
A method for preparing a patient's chest having an exposed skin surface for accepting a defibrillator paddle, said method comprising: taking a laminated defibrillator pad having a bottom layer of electrically conductive polymer which is tacky so as to adhere to most surfaces it contacts, said pad having an upper layer comprising fabric material formed from filamentous carbon, said upper layer being adhered to and in electrical contact with said bottom layer; placing said pad on said patient's chest with said bottom layer in contact with said exposed skin surface of said patient's chest whereby said tackiness of said bottom layer will cause said pad to be detachably adhered to and in electrical contact with said exposed skin surface of said patient's chest; and placing said defibrillator paddle in facing engagement with and in electrical contact with said upper layer of said pad whereby said pad will provide electrical continuity from said defibrillator paddle to said exposed skin surface of said patient.
Claim 3
Dependent Claim
61 words
A method according to claim 1 and further comprising removing said defibrillator paddle from electrical contact with said upper layer of said pad, said upper layer at least partially shielding said defibrillator paddle from said tackiness of said bottom layer whereby said pad will remain adhered to said exposed skin surface after removal of said defibrillator paddle from said upper surface.
Claim 4
Dependent Claim
40 words
A method according to claim 2 wherein said upper layer of said pad comprises pure carbon, said method further comprising placing said defibrillator paddle in facing engagement with and in electrical contact with said pure carbon of said upper layer.
Claim 5
Dependent Claim
40 words
A method according to claim 2 wherein said upper layer of said pad comprises nickel-plated carbon, said method further comprising placing said defibrillator paddle in facing engagement with and in electrical contact with said filamentous carbon of said upper layer.
Claim 6
Dependent Claim
219 words
A combination adapted to be applied to an exposed skin surface of a patient's chest comprising: a laminated defibrillator pad having a bottom layer of electrically conductive polymer which is tacky so as to adhere to most surfaces it contacts, said pad having an upper layer comprising fabric material formed from filamentous carbon; said bottom layer being adapted to be in contact with said exposed skin surface of said patient's chest whereby said tackiness of said bottom layer causes said bottom layer to be detachably adhered to and in electrical contact with said exposed skin surface; said upper layer having openings therein: said bottom layer exuding upwardly through said openings so as to create a plurality of protrusions which are exposed upwardly through said openings of said upper layer; a defibrillator paddle having an electrode surface in facing engagement with and in electrical contact with said upper layer of said pad and said protrusions of said bottom layer which are exposed upwardly through said openings of said upper layer; said upper layer at least partially shielding said defibrillator electrode surface from said tackiness of said bottom layer whereby said electrode surface adheres to said defibrillator pad with an adhering force which is less than the adhering force between said bottom layer and said exposed surface of said patient's skin.
Claim 7
Dependent Claim
219 words
A combination adapted to be applied to an exposed skin surface of a patient's chest comprising: a laminated defibrillator pad having a bottom layer of electrically conductive polymer which is tacky so as to adhere to most surfaces it contacts, said pad having an upper layer comprising fabric material formed from filamentous carbon; said bottom layer being adapted to be in contact with said exposed skin surface of said patient's chest whereby said tackiness of said bottom layer causes said bottom layer to be detachably adhered to and in electrical contact with said exposed skin surface; said upper layer having openings therein: said bottom layer exuding upwardly through said openings so as to create a plurality of protrusions which are exposed upwardly through said openings of said upper layer; a defibrillator paddle having an electrode surface in facing engagement with and in electrical contact with said upper layer of said pad and said protrusions of said bottom layer which are exposed upwardly through said openings of said upper layer; said upper layer at least partially shielding said defibrillator electrode surface from said tackiness of said bottom layer whereby said electrode surface adheres to said defibrillator pad with an adhering force which is less than the adhering force between said bottom layer and said exposed surface of said patient's skin.
Claim 8
Dependent Claim
15 words
A combination pad according to claim 5 wherein said upper layer comprises 100 percent carbon.
Claim 9
Dependent Claim
14 words
A combination pad according to claim 5 wherein said upper layer comprises nickel-plated carbon.
Claim 10
Dependent Claim
30 words
A combination pad according to claim 5 wherein said fabric material comprises carbon fibers having a density of from 0.35 ounces per square yard to 0.5 ounces per square yard.
