Abstract

Sistema de suministro osmótico, que comprende: una cápsula, estando dotada dicha cápsula de un interior para el alojamiento de un agente beneficioso, presentando dicho interior una superficie interior; un agente osmótico situado en dicho interior; un cuerpo semipermeable en comunicación de líquido con dicha cápsula para permitir que un líquido se infiltre a través de dicho cuerpo semipermeable hasta dicho agente osmótico; y un pistón situado dentro de dicho interior de dicha cápsula, el cual puede desplazarse con respecto a dicha superficie interior de dicha cápsula, determinando una obturación móvil con dicha superficie interior de dicha cápsula que separa dicho agente osmótico de dicho agente beneficioso, y presentando un rebaje que recibe por lo menos una parte de dicho agente osmótico, dicho agente osmótico, que se encuentra situado entre dicho pistón y dicho cuerpo semipermeable, tiene por objeto embeber líquido de un ambiente envolvente a través de dicho cuerpo semipermeable para provocar que dicho pistón se desplace, produciendo a su vez una descarga del agente beneficioso de dicha cápsula.
