Blood treatment system having pulsatile blood intake

A blood treatment system comprising:

• a blood pump including:
• a first blood pump chamber operable with a first inlet valve and a first outlet valve, the first blood pump chamber including a first blood pump diaphragm, and
• a second blood pump chamber operable with a second inlet valve and a second outlet valve, the second blood pump chamber including a second blood pump diaphragm;
• an arterial blood line;
• a venous blood line;
• a dialyzer placed in fluid communication with the arterial and venous blood lines;
• and
• a processor configured to move the first and second blood pump diaphragms so as to achieve a pulsatile pattern of filling the first and second blood pump chambers completely with blood and an at least substantially constant pattern of discharging blood from the first and second blood pump chambers.

• a dialyzer placed in fluid communication with the arterial and venous blood lines;
• and
• a processor configured to move the first or second blood pump diaphragm so as to perform a pulsatile pattern of blood filling in which the first or second blood pump chamber is filled completely with blood, and wherein the blood filling movement is performed faster than the other of the first or second blood pump diaphragm is moved to perform a blood discharge, and wherein the blood discharge has a constant pattern of discharging blood.
