L'INVENTION CONCERNE LES APPAREILLAGES MEDICAUX.LE DEFIBRILLATEUR, OBJET DE L'INVENTION, EST CARACTERISE EN CE QU'IL EST MUNI D'UN APPAREIL D'ELECTRONARCOSE 10 COMPRENANT UN BLOC 11 ASSURANT LA FORMATION ET LE DECLENCHEMENT DU COURANT ANESTHESIQUE ET COMPORTANT UNE ENTREE ET DEUX SORTIES, AINSI QU'UN FORMATEUR 12 DE SIGNAL DE DECLENCHEMENT DE LA DEFIBRILLATION, L'ENTREE DUDIT BLOC DE FORMATION ET DE DECLENCHEMENT DU COURANT ANESTHESIQUE ETANT CONNECTEE A LA SORTIE DU PREMIER CIRCUIT DE COINCIDENCE 8, UNE PREMIERE SORTIE DUDIT BLOC DE FORMATION ET DE DECLENCHEMENT DU COURANT ANESTHESIQUE ETANT CONNECTEE A L'ENTREE DU FORMATEUR 12 DE SIGNAL DE DECLENCHEMENT DE LA DEFIBRILLATION, DONT LA SORTIE EST A SON TOUR RELIEE A LA DEUXIEME ENTREE DU DEUXIEME CIRCUIT DE COINCIDENCE 9, TANDIS QUE LA DEUXIEME SORTIE DUDIT BLOC DE FORMATION ET DE DECLENCHEMENT DU COURANT ANESTHESIQUE EST RELIEE AUX ELECTRODES 13 DE L'APPAREIL D'ELECTRONARCOSE 10.L'INVENTION S'APPLIQUE NOTAMMENT AU TRAITEMENT DES ARYTHMIES CARDIAQUES DE CARACTERE CHRONIQUE ET AIGU. A defibrillator comprises a discharging circuit provided with a storage capacitor, a controlled contactor, and electrodes for defibrillation connected in series therebetween. The output of a voltage source and a control unit for adjusting and controlling a voltage across the capacitor are connected to the capacitor. The voltage source input is connected to the output of the control unit. The defibrillator comprises two AND gates, each having two inputs and an output, a unit for starting defibrillation, and an electronarcosis device. The first AND gate has an input connected to the output of the control unit. The first AND gate has a second input connected to the unit for starting defibrillation, while the first AND gate output is connected to the first input of the second AND gate. The second AND gate output is connected to the controlled contactor input. The electronarcosis device comprises a shaping unit for shaping and starting a narcotizing current having an input and two outputs, a signal shaper for starting defibrillation, and electrodes for narcosis. The shaping unit input, is connected to first AND gate output, while the first output is connected to the signal shaper input and the second output is connected to the electrodes for narcosis. The signal shaper output is connected to the second input of the second AND gate.
