Connection circuit and method for using monitor/defibrillator
First Claim
1. In a system for monitoring and defibrillating the heart of a patient, said system including a monitor/defibrillator, and improved means for connecting the monitor/defibrillator to said patient and for selectively applying a pulse of energy to the patient for defibrillation, comprising:
- a first and a second electrode;
a first conductor for electrically connecting said firs electrode to said monitor/defibrillator;
a second conductor for electrically connecting said second electrode to said monitor/defibrillator;
a switch module mounted on but in electrical isolation with said first and second conductors, said switch module positioned on said first and second conductors remotely from said first and second electrodes;
a third conductor for connecting said switch module to said monitor/defibrillator for establishing a signal indicative of defibrillation when said switch module is actuated;
means responsive to said signal indicative of defibrillation for causing said monitor/defibrillator to provide said pulse of energy through said first and second electrodes to said patient for defibrillation.

Abstract
A circuit for connecting a monitor/defibrillator to a patient and a method for monitoring the condition of the heart and for selectively applying a pulse of energy to the patient for defibrillation. A first and a second electrode are adhesively secured to the patient. The electrodes form an assembly which is coupled to a connection circuit leading to the monitor/defibrillator. A switch module is mounted on the connection circuit and is positioned remotely from the patient. The switch module has a plurality of operator-actuated switches which, when depressed, cause the monitor/defibrillator to provide a pulse of energy to the electrodes for defibrillation. The switches are arranged so that both hands of the operator are required to simultaneously close them, thereby assuring that the ends of the operator are remote from the patient during defibrillation.

11. In an operator-controlled system for defibrillating the heart of a patient by the application of a pulse of energy applied to the heart, the improvement comprising:
-
a first and a second electrode adapted to be secured to the patient, thereby obviating the need for the hands of said operator to be proximate said patient; and a switch module having a top, a bottom, two sides and two ends located remotely from said electrodes and having four operator-actuated switches therein which, when simultaneously actuated, cause the system to apply said pulse of energy to said first and second electrodes, two of said switches positioned on each of said side of said module so that both hands of said operator are required to simultaneously close said switches, thereby assuring that said hands of said operator remain remotely positioned from said electrodes during defibrillation. - View Dependent Claims (12)

13. A system for connecting a monitor/defibrillator to a patient for monitoring the heart and for providing a pulse of energy to the heart for defibrillation thereof, comprising:
-
a monitor/defibrillator; an electrode assembly including; a first and a second electrode similarly constructed and each having a base of nonconductive flexible material; a conductive foil secured to the upper surface of said base; a cover of flexible nonconductive material overlying a portion of said base and secured to the upper surface of said base, said cover having an aperture therein, and said foil being exposed through said aperture; a conductive gel-impregnated sponge disposed within said aperture; an adhesive coating applied to the exposed surface of said cover; an electrical lead connected to said foil; and a removable protective sheet overlying the adhesive coating and said conductive gel-impregated sponge; and a first connector means coupled to the lead from each electrode; a second connector means coupled to the first connector means; a first conductor for electrically connecting said second connector means and said monitor/defibrillator; a switch module mounted on said first conductor remotely from said electrodes and having a plurality of operator-actuated switches connected in series with each other; a second conductor connecting said plurality of switches connected in series with each other to said monitor/defibrillator for providing a signal indicative of defibrillation when said switches are simultaneously actuated; and means responsive to said signal for applying the pulse of energy to the heart for defibrillation thereof.
