A tubular set for the conveyance of blood includes flexible set tubing and a bubble trap chamber connected to the tubing for any desired extracorporeal blood transport process. The bubble trap chamber includes a housing defining an outer wall, a flow inlet to the interior of the housing, and a flow outlet at or near the bottom of the housing. The housing also includes an inner wall adjacent to its top. The inner wall is radially inwardly spaced from the outer wall within the chamber, extending circumferentially and generally parallel to the outer wall for at least about 90.degree. of the circumference of the outer wall and preferably at least 180.degree., to define a circumferential passageway between the inner and outer walls. The flow inlet communicates with the circumferential passageway, so that blood can be directed to flow from the inlet horizontally and circumferentially through the passageway to a pair of passageway outlets. The passageway outlets are spaced in the chamber from the inlet, with the effect that the horizontal blood flow path of blood in the chamber is lengthened with less flow velocity, which improves the bubble removal capability of the bubble trap chamber.
