Abstract: A bubble oxygenator having a generally cubic exterior housing with a gas dispersion system having a one-way valve that prevents the backflow of blood into the oxygen supply. At one end of the oxygenator housing is a generally vertically extending bubble chamber having a movable wall to vary the flow capacity of the oxygenator. Formed separately from the bubble or oxygenating chamber is a generally horizontally extending bubble collection chamber in the top of the cubic housing. The bubble collection chamber is formed by a rectangular envelope shaped, defoaming mesh and filter assembly. A planar temperature controlled ramp receives debubbled blood from the bubble collection chamber and directs it in planar fashion downwardly toward the reservoir.

Abstract: A surgical suction system which may be driven in a plurality of different ways. The basic component of the system is an enlarged container having an inlet and an outlet and being formed of a resilient material of the type which restores itself to its original shape following distortion from the original shape. The inlet is connected to apparatus for insertion to an area of a patient to be drained and includes a check valve for allowing fluid to pass into the container through the inlet while precluding substantial backflow. The outlet may be connected to a check valve and/or a regulated vacuum source. The walls of the container include pleated formations so that the same may be compressed to reduce the volume to establish a vacuum therein.
