The Hemovac® Autotransfusion System (H.A.S.® Autotransfusion System) from Zimmer is a fully integrated, completely portable blood management system that does not depend on external sources such as wall suction or batteries to operate. Because wall suction is not needed, the risk of hemolysis can be reduced. The blood filter system’s low, gentle suction helps ensure the overall quality of blood to be reinfused. The Hemovac Autotransfusion System provides everything needed for collection of post-operative drainage of the patient’s own blood and for continued wound drainage after reinfusion: a collection unit, wound drainage tubing, dual trocars and an evacuator. By utilizing the H.A.S. evacuator and collection bag for wound drainage post-reinfusion, the clinician’s exposure to the patient’s blood and body fluids can be minimized.
