Abstract
A blood reservoir may be used in combination with other elements such as a heart lung machine (HLM), oxygenator, heat exchanger, arterial filter and the like to form an extracorporeal blood circuit that may be employed in a procedure such as a bypass procedure. The blood reservoir may be configured to receive, filter and store blood from a number of sources including vent blood (from within the heart), venous blood (from a major vein), purge blood (from a sampling line) and cardiotomy or suction blood (from the surgical field).
