ABSTRACT:
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.
