Abstract

1455772 Dialysis apparatus HYDRONAUTICS INC 17 Jan 1974 02298/74 Heading B1X Apparatus for removing toxic substances from body fluids comprises dialysis means containing a selective membrane for removing toxic solutes from the body fluid; means for conveying the 'body fluid to one side of the membrane of the dialysis means; means for conveying a water-containing dialysate substantially free of said toxic solutes to the other side of the membrane to establish a solute concentration gradient and to cause their diffusion across the membrane; dialysate purification means comprising a hyperfiltration means having a plurality of hyperfiltration membranes with hyperfiltration characteristics enclosed and supported in a housing, said housing having influx means, filtrate efflux means, and toxic solute efflux means for removing the toxic solutes from said dialysate; means for conveying spent dialysate containing toxic solutes from the dialysis means to the dialysate purification means, and spent dialysate conveying means being constructed and arranged to permit the interposition between the dialysis means and the dialysate purification means of a means for overcoming osmotic back pressure in the dialysate purification means; and means for returning purified dialysate to the dialysis means. The body fluid treated may be blood or peritoneal fluid. The dialysis membranes may be cellulose-based or of polyvinyl alcohol; they may be plane or tubular and may be treated e.g. with heparin so as to be non- thrombogenic. The hyperfiltration membranes may be sheets of cellulose acetate.
