A surgical blood sucker and peristaltic pump combination discharge a three-phase mixed stream of blood, air and surgical tissue debris into a cardiotomy reservoir through a slot shape blood inlet nozzle tangentially disposed on the wall of the blood reservoir volume. The tissue debris is collected internally in the reservoir on the reservoir base filter face and the face of the conical air filter. The air, under slight pressure in the reservoir, exits from the reservoir through the air filter and a relief valve. The defoamed blood flows from the reservoir through multiple base filter plate exit apertures, into a blood oxygenator.
