  • Publication number: 20230132087
    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.

  • Publication number: 20230045644
    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.

  • Patent number: 10987264
    Abstract: A patient support apparatus includes a frame and a mattress positioned on the frame. A respiratory therapy device is coupled to the frame. The respiratory therapy device includes a blower having an inlet and an outlet, a patient interface, and a valve including a valve member that is rotatable through a first angular displacement in a first direction from a first position to a second position. The outlet of the blower is coupled to the patient interface so that positive pressure is provided to a patient's airway via the patient interface when the valve member is in the first position. The inlet of the blower is coupled to the patient interface so that negative pressure is provided to the patient's airway via the patient interface when the valve member is in the second position.
