A hemodialyzer apparatus comprises a reusable dialyzer membrane as well as reusable blood flow path and dialysis flow path units. The apparatus automatically primes itself and makes dialysis solution from dry chemicals, concentrates, and fresh water which is provided to the apparatus. Also, after use, the apparatus automatically prepares cleaning and rinsing solution for the cleaning and rinsing of the dialyzer membrane as well as the dialyzate and blood flow path means, to provide a system which is so simplified in terms of automatic operation that it may be usable for daily dialysis at home.

[ That which is claimed:] [8.] A hemodialyzer apparatus, which comprises;a dialyzer membrane having first and second sides;a dialyzate flow path positioned for passing dialysis solution across the first side of said membrane;a blood flow path positioned for passing blood across the second side of said membrane for dialysis thereof;a solution storage tank connected to said dialyzate flow path and having a capacity large enough to hold substantially all dialysis solution used in a clinical dialysis procedure;venous and arterial connectors communicating with said blood flow path for communication with a vascular system of a patient;a water inlet conduit;a first conduit communicating with said tank and said water inlet conduit to receive water therefrom; apparatus for automatically providing desired amounts of dialysis solution solutes to said water in a manner providing water containing said dialysis solution solutes in dispersed form in said solution storage tank, to thus provide a desired quantity of said dialysis solution in a first operating mode; and valve and control means to selectively and automatically provide and control fluid flow throughout the apparatus;said hemodialyzer apparatus also comprising a third conduit, connected to said first conduit, having apparatus for carrying desired amounts of hemodialyzer apparatus cleaning agent plus a receptacle for containing said agent to permit purified water from the first conduit to pass through said third conduit and to disperse said agent and to convey it to said solution storage tank to provide a desired quantity of antimicrobial cleaning solution in a second operating mode.
