Abstract
1331896 Hemodialyser UNITED STATES ATOMIC ENERGY COMMISSION 15 May 1972 [3 Feb 1972] 22686/72 Heading B1X A hemodialyzer comprises a rectangular casing containing a plurality of flattened semipermeable membrane tubes arranged in parallel in a stack therein; a dialysate inlet and a dialysate outlet located on opposite ends of said casing; means associated with said dialysate inlet and outlet for passing dialysate fluid through said hemodialyzer within said flattened tubes; a blood inlet port located on a side of the casing at one end thereof and a blood outlet port located on a side of the casing at the opposite end thereof, each of said two blood ports being a tubular conduit mounted across the width of a side of the hemodialyzer casing; means associated with said blood ports for passing blood through said hemodialyzer across and between said flattened tubes; and means for causing the blood to flow in a sinuous path in its passage from said blood inlet port to said blood outlet port, whereby the blood flows across the flattened tubes a multiple number of times. As shown, 2 indicates one surface of one of a stack of flattened tubes; 3 and 4 are the inlet and outlet for dialysis fluid, 7 and 8 are the inlet and outlet for blood; 9 and 10 are baffles which cause the blood as shown by the arrows to flow three times across the surface of the tubes.
