ABSTRACT:
A flow-through blood treatment device such as a hemodialyzer comprises a housing, a blood inlet, a blood outlet, and at least one membrane in the housing defining a blood flow path between the blood inlet and outlet on one side of the membrane, plus a second flow path defined on the other side of the membrane. At least one of the blood inlet and outlet is connected to blood flow tubing, which blood flow tubing carries a connector spaced from the housing for access to the vascular system of a patient. The blood flow tubing also defines at least one connection site along its length permitting repeated, temporary connection and subsequent disconnection with branch conduits, for connection with sources of additive solutions or measuring devices. Typically, the blood flow tubing is free of permanently attached, flexible branch tubings.
