Abstract
Abstract A defibrillation electrode having a handled metal electrode disc, to which is connected a gauze pad capable of holding a saline solution, the gauze pad and disc being held in an electrically connected state by an annular resilient holder ring. In the preferred embodiment, the gauze pad has a metal plate attached to one side thereof which is integrally connected to the holder ring. The metal plate is pressed against the electrode disc when the electrode disc is snapped into the resilient holder ring, thereby providing reliable conduction from the disc through the metal plate and gauze pad, to the patient. The combination of defibrillation electrode and attached gauze pad permits rapid and reliable defibrillation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
Defibrillation electrode apparatus for applying electrical shock energy to a patient, comprising: a. an electrode disc having opposite surfaces; b. a support plate integrally connected to a first of said disc surfaces; c. gauze means for receiving and holding a conductive solution, having a support surface in contact with the second surface of said electrode, said support surface having outer tab portions turned radially inward so as to hold said gauze means in crimped engagement with said plate and also radially outward extending portions; d. annular clamping means for holding said disc and said gauze means in clamped engagement such that good electrical contact is maintained between said disc and said gauze means; and e. a handle connected to said support plate having insulated leads extending therethrough and connecting to said disc, through which defibrillation shock energy can be transmitted.
Claim 2
Dependent Claim
140 words
Defibrillation electrode apparatus for applying electrical shock energy to a patient, comprising: a. an electrode disc having opposite surfaces; b. a support plate integrally connected to a first of said disc surfaces; c. gauze means for receiving and holding a conductive solution, having a support surface in contact with the second surface of said electrode, said support surface having outer tab portions turned radially inward so as to hold said gauze means in crimped engagement with said plate and also radially outward extending portions; d. annular clamping means for holding said disc and said gauze means in clamped engagement such that good electrical contact is maintained between said disc and said gauze means; and e. a handle connected to said support plate having insulated leads extending therethrough and connecting to said disc, through which defibrillation shock energy can be transmitted.
Claim 3
Dependent Claim
43 words
The apparatus as described in claim 1 wherein said annular clamping means contains a first annular groove which receives said support plate, and a second annular groove which receives said radially outward extending portions, and is composed of a resilient and non-conducting material.
Claim 4
Dependent Claim
28 words
The apparatus as described in claim 2 wherein said support surface comprises a screen, the outer periphery of which is received and held in said annular clamping means.
