Abstract
A membrane oxygenator may receive a supply of pressurized oxygen and a supply of pressurized fluid, such as water or blood. In one example, a plurality of tubular membranes are disposed in a housing, where the pressurized fluid is delivered into the tubular membranes and where the pressurized oxygen is delivered into the area surrounding the tubular membranes. The oxygen diffuses through the membranes of the oxygenator to produce an oxygenated fluid. Advantageously, the oxygenated fluid is oxygen-saturated and delivered to a high pressure vessel where it may be stored until it is delivered to a patient.
