Abstract

Un aparato y método se describen para la detección de la desconexión de un dispositivo de acceso vascular, como una aguja, cánula o catéter de un vaso sanguíneo o segmento del injerto vascular; un par de electrodos se coloca en contacto directo con el fluido o sangre en comunicación fluida con el segmento vascular; en una modalidad, los electrodos se incorporan en un par de conectores que conectan los catéteres arteriales y venosos a los tubos arteriales y venosos que conducen hacia y desde un aparato de flujo de sangre extracorpórea; los cables que conducen desde los electrodos a un circuito de detección se pueden incorporar en un par de tubos arteriales y venosos de doble lumen que conectan el aparato de flujo de sangre con el vaso sanguíneo o injerto vascular; el circuito de detección está configurado para proporcionar una señal de corriente alterna de bajo voltaje a los electrodos para medir la resistencia eléctrica entre los electrodos, minimizando tanto la duración como la cantidad de corriente que se está suministrando; la detección de un aumento en resistencia eléctrica entre los electrodos que excede un valor umbral predeterminado puede ser utilizada para indicar una posible desconexión del dispositivo de acceso vascular.
