Abstract

1462349 Peritoneal dialysis with hyperfiltration HYDRONAUTICS INC (H S Hodding) 17 Jan 1974 13029/76 Divided out of 1455772 Heading B1X [Also in Division A5] A portable and wearable device for continuously removing toxic metabolites from. blood comprises means for continuously circulating a prepared solution through the peritoneal cavity to draw toxic metabolites from the blood across the peritoneal membranes and into the fluid in the cavity forming peritoneal fluid, filtration means comprising a plurality of membranes with hyperfiltration characteristics for removing the toxic substances from the peritoneal fluid, means for continuously conveying the peritoneal fluid from the peritoneal cavity to the filtration means, means for pressurising the peritoneal fluid conveyed to the membranes to provide a pressure differential across the membranes, means for continuously recycling purified filtrate from the filtration means back to the peritoneal cavity, and means for reconstituting the recycled peritoneal fluid to make it suitable for re-use in the peritoneal cavity. As shown, dialysis fluid is withdrawn from the peritoneum and pumped through filter unit 210 containing a hyperfiltration membrane 212. Purified fluid is withdrawn from the unit by line 218 and returned to the peritoneum. Make-up solution may be added to the outlet side of the filter from reservoir 230.
