Abstract
An organ preservation system includes a housing, an organ perfusion circuit disposed within the housing, and a dual direction bubble trap disposed within the organ perfusion circuit. The dual direction bubble trap can include an upper interior chamber, a lower interior chamber, an air vent valve, and a hydrophobic membrane disposed between the upper interior chamber and the air vent valve. During operation, when fluid is pumped by a fluid pump into the dual direction bubble trap from either a retrograde or antegrade direction, air passes through the hydrophic membrane and is vented through the air vent valve until such time that the interior chamber is full of fluid which causes the air vent valve to close. Related apparatus, systems, techniques and articles are also described.
