Abstract: A user-replaceable receptacle for an oxygen concentrator includes a containment structure and a desiccant disposed within the containment structure. An inlet end of the containment structure allows feed gas to be introduced into the desiccant. An outlet end of the containment structure allows the feed gas to exit the containment structure. A connection mechanism couples the outlet end of the containment structure to a gas separation adsorbent. The connection mechanism is operable between an unconnected position and a connection position. The desiccant in the user-replaceable receptacle removes water moisture from the feed gas prior to exiting the outlet end of the containment structure, thereby reducing exposure of the gas separation adsorbent to water.

Abstract: A sieve bed assembly monitoring system is disclosed. The system includes a sieve bed assembly including a canister having an intake; adsorbent material to produce oxygen enriched air from compressed air in a swing adsorption process; and an identification device including identification data for the sieve bed assembly, wherein the identification data is capable of uniquely identifying the sieve bed assembly. The system includes an oxygen concentrator having a retention mechanism to retain the sieve bed assembly, a compressor supplying compressed air to the intake of the canister, a controller, a transceiver and a reader operable to read the identification data from the identification device. The controller reads the identification data and transmits the read identification data via the transceiver. A remote external device receives the read identification data from transceiver.
