Abstract

See full text

A system for dialyzing blood in which blood is passed through an exchange station to transfer toxic material across a semipermeable membrane to a dialyzate. Pump means are disclosed for simultaneously pumping a plurality of liquids through the system at different flow rates. The pump means is provided with mechanism for stopping the flow of dialyzate while retaining the blood pumping capability.
