Abstract

Sistema para la dosificación controlada y pasiva de fluidos, de preferente uso clínico, caracterizado por un dispositivo volumétrico constituido por una cámara rígida subdividida mediante dos diafragmas en tres cámaras elásticas cuya suma de volumen preseleccionable coincidiendo este volumen con el del líquido inerte que la rellena con lo cual se preselecciona la suma de los volúmenes de las otras dos cámaras elásticas y, por estar la entrada y salida del flujo en éstas gobernado por cuatro válvulas de dos vías que abren y cierran de modo cruzado.
