Estimating the term…
Apparatus for the treatment of fluids are disclosed including a cylindrical housing closed at both ends by end caps, one of which includes an inlet for a fluid and the other includes an outlet for the fluid, a plurality of hollow fibers are arranged longitudinally within the housing between a pair of end walls, and one of the end caps includes an outlet for a second fluid which can thus be withdrawn from the outer surface of the hollow fibers between the end walls, and the apparatus includes a ring mounted between the hollow fibers at one of the end caps in order to create a fluid channel for the second fluid between the ring and the inner wall surface of the housing. This apparatus can be used, for example, for hemofiltration, hemodiafiltration or hemodialysis, but it may also be generally used for dialysis or filtration and purification of sewage, and for heat transfer, or as an oxygenator.
Apparatus for the treatment of fluids comprising a cylindrical housing having a first open end, a second open end, and an inner wall surface, first and second end caps for closing said first and second open ends of said cylindrical housing, one of said first and second end caps including an inlet for said fluid, and said other of said first and second end caps including an outlet for said fluid, a pair of end walls at said first and second ends of said cylindrical housing, a plurality of hollow fibers arranged longitudinally within said housing between said pair of end walls, at least one of said first and second end caps including outlet means for a second fluid whereby said second fluid can be withdrawn from the outer surface of said plurality of hollow fibers between said pair of end walls, and ring means mounted between said plurality of hollow fibers and said inner wall surface at said at least one of said first and second end caps so as to create a fluid channel for said second fluid between said ring means and said inner wall surface of said cylindrical housing for optimal distribution of said second fluid.
