Abstract

Mejoras en dispositivos de administración de líquidos parentéricos en unidades secuenciales, que comprenden medios tubulares para efectuar dicha administración a un paciente, medios para la conexión de tal dispositivo a una fuente de suministro del referido líquido y una cámara agrandada que contiene este líquido, situada en comunicación de flujo con aquellos medios tubulares, incluyendo dicha cámara una abertura de flujo inferior y una válvula que controla el flujo a través de la citada abertura, caracterizadas en que la válvula incluye, combinadamente, una bola flotante, un asiento valvular situado alrededor de la mencionada abertura de flujo inferior y destinado a recibir la bola en forma hermética al aire cuando no haya líquido suficiente para que flote y unos medios de retención dotados de una abertura, que rodean la bola y presentan unas proporciones tales que permiten a ésta flotar en relación espaciada respecto al asiento valvular en presencia del líquido que pasa a través de los medios de retención dotados de abertura, definiendo estos últimos medios una cámara generalmente cilíndrica que a su vez define un escalón anular en una posición inferior al centro de gravedad de la bola flotadora cuando ésta se halla situada sobre el asiento valvular, siendo de diámetro reducido la porción de la cámara dispuesta por debajo del mencionado escalón, en virtud de lo cual se crea un flujo turbulento de líquido al llenarse con éste dichos medios de retención.
