Abstract
An apparatus for separating gas bubbles that may be entrained in perfusate flow prevents such bubbles from continuing downstream and entering an organ or tissue. The apparatus may include a chamber having a top wall, a bottom wall and side walls. The chamber may include an inlet configured to allow at least one of gas and liquid to enter the chamber, an air opening configured to allow at least gas to exit the chamber and a first liquid opening configured to allow at least liquid to exit the chamber. The apparatus may function as an accumulator that reduces or eliminates pulsatility of the liquid flow and pressure. The apparatus may include a minimum volume of gas, initially or through the accumulation of gas, such that flow and pressure fluctuations in the liquid are dampened or eliminated. The apparatus may include a sampling port in a wall of the chamber.
