Abstract
A reservoir for holding and reprocessing foamy shed blood prior to reintroduction to a patient, the reservoir comprising a holding chamber divided by a filter into two sub-chambers, a foam killing chamber in open communication with one of the sub-chambers, and inlet and outlet ports for the blood. The apparatus removes cell debris and filterable products of hemolysis and avoids the need to return chemical foam killers and collapsed foam to the patient's body.
