A combined dialyzer and adsorber unit in one disposable package. The dialyzer is integral with the adsorber which contains a chemical adsorbent to regenerate a dialysate solution. In a preferred embodiment the dialyzer is mounted in the form of a sleeve around the adsorber container as a core. Dialysate is introduced into the dialyzer, then immediately circulated through the chemical adsorbent contained in the adsorber. There the major components of the impurities dialyzed out from the dialyzer can be adsorbed, whereby the dialysate is regenerated. The sleeve can be the adsorber and the core the dialyzer. In addition, the adsorber can have included therein, either mixed in with the adsorbent material or in a separate compartment, a water soluble dialysate material which can be dissolved by circulating water through the unit prior to starting to dialyze the patient.

An artificial kidney apparatus comprising, in combination, a combined dialyzer and adsorber unit having a cylindrical container having a top cover with an aperture therein and an apertured bottom cover and a mass of adsorbent therein, a flat tube of membrane material permeable to uremic wastes and toxic materials in blood wrapped in a coil around said cylindrical container, a screen layer between each of the coils of the tube, a blood inlet tube connected to one end of the flat tube and a blood outlet tube connected to the other end of the flat tube, said blood tubes extending to the exterior of the sleeve, and a unit cover over said coil around said cylindrical container and over the end of the container having the top cover thereon and being spaced from the top cover sufficiently to give access to the aperture in the cover, the bottom of said cover being completely open for exposing the entire area of the edges of said screen layers toward the bottom of said unit, said container and covers being of a moldable plastic inert to the dialysate, said aperture in said top cover being sufficiently large to receive liquid flowing simultaneously through all of said screen layers around the entire circumference of said screen layers; a dialysate holding tank; a unit holder tank in which said unit is positioned with said unit cover at the top thereof; a dialysate intake line extending from said dialysate tank to unit holder tank; a dialysate pump; a suction line extending from said adsorber outlet to the intake of said dialysate pump; and a return line from the outlet of said dialysate pump to said diaylsate holding tank, whereby when dialysate fills said unit holder tank with the uncovered edges of said screen layers immersed in dialysate and dialysate is caused to flow through the unit, dialysate flows evenly over the turns of the coil along the screen layers around the entire periphery of the unit and all of the coil is utilized for exchange of impurities from the blood within the coil to the dialysate flowing over the outside of the coil.
