Abstract
The arterial blood filter of this invention is for extra-corporeal bypass during cardio-pulmonary surgery. It has an internal divergent blood flow path from the inlet to smoothly reduce blood flow velocity to permit separation of air bubbles with minimum trauma to blood cells. The upper portion of the blood filter housing permits collection of air bubbles and permits their withdrawal. The inlet and outlet connections to the filter are both on the bottom to ease draping of the connecting tubes.
