Abstract

This invention relates to powered medical devices such as portable oxygen generators. A powered portable oxygen concentrator (POC) is described comprising an oxygen concentrator and a heat engine coupled to the oxygen concentrator to power the oxygen concentrator. The oxygen concentrator comprises an inlet port for receiving air; a gas separator configured to separate waste gas from the received air and provide an oxygen enriched gas; an oxygen outlet port for venting the oxygen enriched gas; and an exhaust port for venting the waste gas.
