Abstract
A blood processing unit for use in connection with extracorporeal blood circulation includes a housing including a blood inlet, an upper end cap defining a central inlet opening, and a blood outlet. Blood flows along a blood flow path between the blood inlet and the blood outlet. A plurality of layers of hollow fibers are disposed inside the housing and along the blood flow path. The hollow fibers are fluidly coupled to a gas inlet port and a gas outlet port. The device includes a flow distribution structure for modifying blood flowing along the blood flow path. The structure includes a body having a distal end, a proximal end, and an outer surface extending between the distal end and the proximal end. An inlet configured for connecting with the upper end cap is spaced from the proximal end. A plurality of curved dividers extend between the inlet and the body.
