Abstract
A hemopurification apparatus includes a porous membrane permeable to gas but impermeable to liquid and dividing a container into two mutually-isolated compartments. The apparatus is adapted to remove water from blood by causing the blood to flow through one of the compartments and a fluid, the water vapor pressure of which is lower than that of the blood, to flow through the other compartment, whereby a portion of the water in the blood is allowed to pass as water vapor through the porous membrane.
