Abstract

Una válvula de retención (1; 7¿) para líneas de infusión de uso médico y similares, que incluye un primero y un segundo elementos tubulares (5, 13;2¿, 3¿) que definen un pasadizo corriente arriba (6;5¿) y un pasadizo corriente abajo (14;6¿), un diafragma (17;30¿) de material deformable elásticamente situado transversalmente entre dichos primero y segundo elementos tubulares (5, 13; 2¿, 3¿) y que actúa como sello de fluido en combinación con un asiento (25;25¿) anular de la válvula (25;25¿) para mantener dicha válvula de control normalmente cerrada, en la que una presión del fluido predeterminada en dicho pasadizo corriente arriba (6; 5¿) hace que dicho diafragma (17; 30¿) se flexione con la consecuente apertura de la válvula (1; 7¿), caracterizada porque dicho diafragma (17;30¿) coopera axialmente con un miembro de émbolo (9; 12¿) que se puede deslizar axialmente entre una posición inoperativa retraída y una posición operativa avanzada para producir la flexión controlada de dicho diafragma(17;30¿), y porque la válvula también incluye un medio de control operable manualmente (10; 11¿, 13¿) para desplazar positivamente dicho émbolo (9;12¿) hasta dicha posición operativa y, consecuentemente, producir la flexión controlada de dicho diafragma (17; 30¿).
