Abstract

Dispositivo osmótico para su inmersión en un medio líquido, caracterizado porque comprende una funda semipermeable que define una cavidad totalmente cerrada y que esta sin perforar, excepto en una pluralidad de poros para permitir el flujo de medio líquido hacia dicha cavidad, y medios supuestos dentro de dicha cavidad para hacer que el medio líquidos fluya hacia dicha cavidad a través de dichos poros para llenar totalmente la cavidad y para mantener la forma de la funda bajo la presión osmótica cuando dicha funda se sumerge en el medio líquido.
