Abstract: A sieve bed assembly for an oxygen concentration device is disclosed. The oxygen concentration device including a compressor compressing air. The sieve bed assembly includes a canister including an intake for connection to the compressor. A block of adsorbent material produces oxygen enriched air from the compressed air from the compressor in a swing adsorption process. An outlet is provided for drawing the produced oxygen enriched air.

Abstract: A tank for accumulating oxygen enriched air from an oxygen concentration device is disclosed. The oxygen concentration device includes a canister including a nitrogen-adsorbent material. A compressor is coupled to the canister. The compressor compresses air for the canister to produce oxygen enriched air in a swing adsorption process. The tank includes a closed container for collecting oxygen enriched air produced in the canister. An inlet is coupled to the container. An outlet in the container allows a patient to inhale the collected oxygen enriched air. An adsorbent material within the container adsorbs oxygen enriched air added to the tank from the canister.

Abstract: Methods and apparatus may implement controlled generation of oxygen enriched air in an oxygen concentrator while implementing control that reduces pneumatic imbalance between the concentrator's canisters, such as dynamic pressure imbalance or other pneumatic characteristic. One or more controllers may regulate operation of a compressor that feeds a pressurised air stream to the concentrator's canisters. This may regulate speed of the compressor to a speed set point for generating the pressurised stream. The regulating may involve generating a compressor control signal having a characteristic parameter such as a power parameter. The controller(s) may operate valve(s) in a cyclic pattern so as to produce oxygen enriched air in an accumulator. A cycle of the cyclic pattern may include a plurality of phases, where each of the plurality of phases has a duration. The controller(s) may then generate a dynamic adjustment to the duration(s) based on an evaluation of the characteristic parameter.

Abstract: An oxygen concentrator (100) may have a moisture conditioning system. In some implementations, the concentrator includes a compressor to induce feed gas into the concentrator. A first pathway may receive the feed gas from the compression system. The first pathway may be configured to draw moisture to produce moisture reduced feed gas. The first pathway may lead the moisture reduced feed gas to sieve bed(s) which produce oxygen enriched air with the moisture reduced feed gas. An accumulator may be configured to receive the produced oxygen enriched air from the sieve bed(s). A second pathway from the accumulator may apply the drawn-out moisture to the produced enriched air to produce humidified enriched air. A third pathway may transfer the drawn-out moisture from the first pathway to the second pathway. An outlet coupled with the second pathway may release the humidified enriched air from the concentrator for a user.
