Abstract: A reservoir-and-filter system for receiving fluid and for removing impurities from fluid is provided in an embodiment of the invention. The system includes a housing with at least two cavities; a first cavity with at least one unfiltered-fluid inlet and a second cavity with at least one filtrate outlet. In this embodiment, a filter member is disposed so as to separate the cavities. In addition, a filtrous trap is disposed so as to directly accept fluid as it enters the first cavity, filter it, and minimize clogging of the filter member. A coarse filter shroud providing a funnel shape at the opening of a cup-shaped trap is included in a preferred embodiment. In an embodiment, at least one gas outlet adaptable for connection to a vacuum source is associated with the second cavity. A method for removing impurities from blood within an extracorporeal circuit is also provided in a further embodiment.
