Patent attributes
Hemodialysis and similar dialysis systems including a variety of systems and methods that make hemodialysis more efficient, easier, and/or more affordable, and include new fluid circuits for fluid flow in hemodialysis systems and a blood pump. The blood pump is configured to pump blood to a dialyzer of a hemodialysis apparatus and comprises a pneumatically actuated or controlled reciprocating diaphragm pump. The diaphragm of the pump comprises a flexible membrane formed or molded to conform to a curved inner wall of a pumping chamber or control chamber of the pump, and the diaphragm is pre-formed or molded to have a control side taking a convex shape, so that any elastic tension on the diaphragm is minimized when fully extended into a control chamber of the pump.
