Abstract

1. Perfeccionamientos en aparatos medidores para controlar la circulación de fluido a través de un equipo de infusión, caracterizados en que dichos aparatos comprenden: un alojamiento: un rotor montado en este alojamiento para su rotación alrededor de un eje fijo, cuyo rotor incluye una serie de rodillos presionadores dispuestos alrededor de la circunferencia de aquél; medios que incluyen una placa presionadora para situar un segmento de tubería del equipo de administración en acoplamiento compresivo con una porción por lo menos de aquellos rodillos, con lo que se bombea fluido a través del segmento de tubería con la rotación del rotor; medios que incluyen un motor escalonador para accionar el rotor; medios accionadores del motor para generar impulsos escalonadores a aplicar al citado motor, proporcionando cada uno de estos impulsos escalonadores un flujo de volumen creciente y predeterminando a través del segmento de tubería; medios que incluyen un registro bidireccional sensible a los impulsos escalonadores para interrumpir la aplicación de éstos al motor al alcanzar dicho registro un estado predeterminado de conteo de referencia; y medios preajustadores de volumen para establecer un estado de conteo inicial en el citado registro, de modo que el contador alcance dicho estado de conteo de referencia tras la infusión de dicha cantidad predeterminada de fluido.
