Patent attributes
Methods and system for concentrating oxygen include a plurality of sieve beds configured to absorb nitrogen from air, at least one reservoir configured to store oxygen-enriched gas exiting from the plurality of sieve beds, a compressor configured to deliver air at one or more desired pressures to the plurality of sieve beds, a support member positioned in housing and configured to support the compressor, the plurality of sieve beds and the reservoir, an air manifold providing a plurality of channels therein that at least partially define passages communicating between the compressor and the plurality of sieve beds, and an oxygen delivery manifold providing a plurality of channels therein that at least partially define passages for delivering the oxygen-enriched to a user. The air manifold and the oxygen delivery manifold are integrally formed with the support member.
