Abstract

EL ELECTRODO NEUTRO DE VARIAS PARTES (1) COMPRENDE TRES ELECTRODOS PARCIALES SUPERFICIALES (2,3,4), YUXTAPUESTOS VERTICAL U HORIZONTALMENTE. A FIN DE UN CONTROL MAS EFICAZ DE LAS POSICIONES DE LOS ELECTRODOS PARCIALES EN EL CUERPO DEL PACIENTE, EL ELECTRODO ESTA CONSTRUIDO DE MANERA QUE LOS DOS ELECTRODOS PARCIALES EXTERIORES (2,4) TENGAN SUPERFICIES DE CONTACTO ESENCIALMENTE TRIANGULARES, QUE LAS ARISTAS LARGAS (HIPOTENUSAS 8 Y 9) DE LOS ELECTRODOS PARCIALES EXTERIORES SE EXTIENDAN DISTANCIADA Y PARALELAMENTE, UNO RESPECTO AL OTRO, Y QUE UN ELECTRODO PARCIAL CENTRAL FAJADO (3) VA SITUADO ENTRE LAS HIPOTENUSAS DE LOS DOS ELECTRODOS EXTERIORES. MEDIANTE ESTA DISPOSICION Y FORMA DEL ELECTRODO SE EVITA UN EJE DE SIMETRIA DE DESPRENDIMIENTO, A LO LARGO DEL CUAL EL ELECTRODO NEUTRO PODRIA DESPEGARSE DEL CUERPO DEL PACIENTE DE TAL MODO, QUE LA ALARMA DE DESPRENDIMIENTO DE LA CONEXION DE VIGILANCIA NO SE ACTIVARA HASTA QUE EL ELECTRODO SE HUBIERA DESPEGADO DEL PACIENTE EN TAL GRADO, QUE ESTE CORRIERA PELIGRO DE QUEMARSE.
