Abstract

La presente invención se refiere a un dispositivo de infusión, caracterizado porque comprende: una bomba de infusión para transferir un líquido a través de un conducto de infusión de una fuente separada del líquido a un paciente; un detector de burbujas, para detectar la presencia de una burbuja de aire en el conducto de infusión; y un control responsivo al detector de burbujas, para determinar si el tamaño de la burbuja de aire es inaceptable; el cual control está configurado para determinar si durante el tiempo que se detecta la burbuja de aire, ésta avanza una distancia indicativa de un tamaño inaceptable.
