Abstract: A bubble-type blood oxygenator which comprises a flexible envelope having a blood flow passage with a blood oxygenating portion and a blood defoaming portion. A stiff backing carries the oxygenator in flat, stretched-out configuration with the result that the flow passage, when filled with blood and oxygen, exhibits reduced outward distension and sagging.

Abstract: A reservoir for the collection, purification, and storage of blood during surgical procedures which comprises a hollow blood storage casing having a hollow, perforated member within said casing extending from end-to-end thereof. Blood defoaming means and a filter are carried by the hollow member, so that the blood defoamer and filter are noncollapsible, and extend the entire length of the chamber within the casing, with one of the ports communicating with the interior of the hollow member, so that blood passes through the perforations of the hollow member and defoamer-filter means.

Abstract: An oxygenator for blood which comprises means for removably holding a membrane oxygenator unit, means for conveying blood to a patient through the oxygenator unit in a first flow path and back to the patient, and means for supplying oxygen gas through the oxygenator unit in a second flow path separated from the first flow path in the unit by a semi-permeable membrane. The oxygenator unit holding means carries a plate which has an oxygen inlet manifold port positioned to communicate with a mounted oxygenator unit, to provide a sealed oxygen flow path through the plate into the oxygenator unit.

Abstract: A surgical suction device is provided having a suction tip and a suction motor communicating with the tip by a length of flexible tubing. The improvement of this invention relates to a control for starting and stopping the motor. The control is positioned remotely from the suction tip, while pneumatic pressure varying means, communicating with the control, are positioned adjacent the suction tip. The control is operated in a manner responsive to pressure variations in the pneumatic pressure means.
