Abstract
An apparatus for exchanging substances, such as artificial lung, in which, for raising exchange efficiency by feeding liquid to the outer wall of hollow fiber membranes efficiently without channeling and for reducing the size of the apparatus, an exchanging part comprising a multitude of hollow fiber membrane (3) disposed cylindrically or annularly to permit liquid to flow through the hollow parts is provided, and a pump (P) is disposed on the inner periphery of said exchanging part so that liquid may continuously be fed to the hollow membrane vertically with respect to the axial direction of said hollow fiber membrane (3).
Claims5
A substance exchanger apparatus which comprises a substance exchanger unit including a multiplicity of hollow fiber membranes, and inlet and outlet means to permit a fluid medium to flow through the hollow part, said hollow fiber membranes being arranged in a tubular or annular column and having a center thereof, and a fluid flow generating means disposed radially inwardly at said center of said column for continuously supplying a liquid medium to the hollow fiber membranes so as to flow in a direction perpendicular to the axial direction of said hollow fiber membranes.
