Hemodynamic swirling of extracorporeal blood

Abstract

Method for maintaining blood substantially free of biochemical coagulation and/or particulate precipitation during extracorporeal treatment of blood. A volume of blood is introduced into a blood container moved in a rotary orbital motion using an orbital vortex motor to generate a sinusoidal wave in the moving blood, thus establishing a laminar flow of the blood in the blood container and over a blood-contacting surface. The blood may be introduced using an intravenous (IV) tube from a vein of a patient, and applying suction pressure to a port of the blood container. An ozonation device may be used to introduce a mixture of oxygen and ozone into the blood container during continued rotary orbital motion. A subsequent positive pressure can be applied to return the blood to the patient. Multiple passes can be performed in succession. Compounds such as anti-coagulant agents may be administered or omitted as required.
