摘要：

An apparatus (10) for perfusing an organ (20) or tissue in a container (50) includes a perfusion circuit for perfusing the organ or tissue; an oxygenator (100) for oxygenating perfusate that circulates through the perfusion circuit; and an oxygen supply device (102) comprising an oxygen concentrator and/or an oxygen generator configured to supply oxygen to the oxygenator. The oxygen generator or concentrator preferably produces oxygen in real time to provide oxygenation to the perfusate, but oxygen may also be produced and stored. The produced oxygen preferably has a concentration greater than the oxygen concentration in air. The oxygen generator may supply oxygen by decomposing water. The oxygen concentrator may be a device that concentrates oxygen by means of pressure swing adsorption, or by way of a solid state oxygen pump.
