    摘要: An oxygen concentrator includes one or more adsorbent sieve beds operable to remove nitrogen from air to produce concentrated oxygen gas at respective outlets thereof, a product tank fluidly coupled to the respective outlets of the sieve bed(s), a compressor operable to pressurize ambient air, one or more sieve bed flow paths from the compressor to respective inlets of the sieve bed(s), a bypass flow path from the compressor to the product tank that bypasses the sieve bed(s), and a valve unit operable to selectively allow flow of pressurized ambient air from the compressor along the one or more sieve bed flow paths and along the bypass flow path in response to a control signal. The valve unit may be controlled in response to a command issued by a ventilator based on a calculated or estimated total flow of gas and entrained air or % FiO2 of a patient.

    摘要: Modular ventilatory support systems and methods are disclosed in which a user may transition the system between a stationary configuration, an extended range configuration, and a stand-alone configuration. The modular components of the system include a compressor unit, a ventilator which may dock with the compressor unit, and a patient interface which may be connected to either the compressor unit or the ventilator unit. By rearranging these modular components into different configurations, mobility and duration of use may be optimized to fit the present needs. In the stationary configuration, mobility is most restricted, but duration of use is maximized. In the extended range configuration, mobility is enhanced, with duration of use limited by the battery power of the ventilator. In the stand-alone configuration, mobility is maximized, with duration of use limited by battery power of the ventilator and the quantity of an external gas supply.

    摘要: In accordance with the present invention, there is provided is provided a tubing arrangement and associated connectors, including a delivery adaptor and a Y-connector, which may be used to facilitate the operative interface of a patient interface to a ventilator within a ventilation system. The delivery adaptor is connected between the outlet connector of the flow generator and the main delivery tube (i.e., the quad-lumen tube) in the ventilation system. The delivery adaptor functions to retain the pneumatic isolation of a sense line of the ventilation system from certain other lumens of the quad-lumen tube, and further connects one of the small lumens of the quad-lumen tube to an external oxygen source or an external humidification source. The oxygen or humidification is delivered to such lumen through the adaptor. The oxygen or humidification is then bled into the air stream at the outlet of such lumen which is at the Y-connector.

    摘要: In accordance with the present invention, there is provided various tubing arrangements and an associated Y-connector which may be used to facilitate the operative interface of the mask to a ventilator within a ventilation system. The tubing arrangement may comprise a pair of bi-lumen tubes. One end of each of the bi-lumen tubes is fluidly connected to the mask, with the opposite end being fluidly connected to the Y-connector. The Y-connector is in turn fluidly connected to one end of either a tri-lumen tube or a quad-lumen tube also included in the tubing arrangement, the opposite end of such tri-lumen tube or quad-lumen tube being fluidly connected to the ventilator. The Y-connector is uniquely configured to fluidly connect certain lumens of the tri-lumen tube or the quad-lumen tube to dedicated, corresponding ones of the lumens included in respective ones of the bi-lumen tubes, and to further allow for the selective detachment of the tri-lumen tube or the quad-lumen tube from the bi-lumen tubes.
