Abstract
Apparatus for oxygenating and pumping blood includes a housing defining a blood flow path including, in series, a gas collection plenum, a pump space and a blood oxygenation element. A pump disposed in the pump space is configured to draw blood from the gas collection plenum and propel blood from the pump space through a heat exchanger and the blood oxygenation element. The heat exchanger includes a heat exchange plate and a coolant space.
Claims7
Apparatus for oxygenating and pumping blood comprising:
- a housing defining a blood flow path including, in series, a gas collection plenum, a pump space and a blood oxygenation space;
- a blood oxygenation element disposed in the blood oxygenation space;
- a solenoid-controlled valve coupled to the gas collection plenum to selectively evacuate gas from the gas collection plenum;
- a pump disposed in the pump space, the pump configured to draw blood from the gas collection plenum and propel blood from the pump space through the blood oxygenation element;
- and
- a heat exchanger comprising a metal alloy disposed and cooperating with the housing to define a wall surface of the pump space.
