Methods and apparatuses for salvaging blood from a patient are disclosed. A blood salvaging and/or blood processing circuit coupled to a cardiopulmonary bypass circuit, cardiotomy circuit, or directly to the patient comprises a hemocentrator for removing water, fluids, and low molecular weight solutes by ultrafiltration and a sorbent-containing plasma separator for removing a selected solute, such as heparin. A combination device for salvaging blood comprises a closed plasma chamber containing a plasma chamber solution, a hollow fiber plasma-separating membrane for receiving blood and permitting plasma to be transported therethrough into the plasma chamber solution and for refiltering the treated plasma back into the blood circuit, a selective sorbent for contacting the selected solute in the plasma and binding the selected solute, and an ultrafiltration membrane for removing water, fluids, and low molecular weight components from the plasma.
