Abstract
A blood reservoir device comprising a generally flexible blood collection chamber having an inlet portion and a main portion. The inlet portion is preferably sized and configured such that blood entering the inlet portion will avoid turbulence and will undergo generally laminar flow through the inlet portion, into the main portion of the chamber. A vent tube is provided for venting coalesced or collected gas bubbles from the top edge of the chamber. Additionally, one or more filter elements may be positioned within the chamber to further facilitate removal of air bubbles from blood passing through the chamber.
