ABSTRACT:
A blood accumulator for use in single needle dialysis systems is provided with elastic walls so that expansion of the accumulator in an outward direction may take place and in the filled condition, the walls are stretched. After the blood input pump is stopped and a valve opened, blood makes its way at a controlled rate out of the accumulator past the dialysis diaphragm back to the patient's body.
