摘要： An arterial line blood filter for use in extracorporeal blood circuits during heart bypass surgery has, among other components, a housing with a cap portion, a base portion, and a generally cylindrical wall portion. The blood filter has a filter element disposed within the housing. An inlet is positioned at an upward angle with respect to the housing and includes an opening in the generally cylindrical wall portion in fluid communication with the inlet chamber. In some embodiments the position of the inlet limits the pressure drop and prime volume of the filter. According to one embodiment, the cap portion has an upwardly sloping inner surface and there is a vent in the cap portion. The inner surface of the cap portion can have a projection proximate the vent configured to limit immobilization of gaseous microemboli within the inlet chamber.
