Abstract: An active exhalation valve for use with a ventilator to control flow of patient exhaled gases. The valve includes a patient circuit connection port, a patient connection port, an exhaled gas port, a pilot pressure port, and a valve seat. The valve further has a movable poppet with inner and outer bellows members and a bellows poppet face. An activation pressure applied to the pilot pressure port extends the bellows members to move the poppet face into engagement with the valve seat and restrict flow of patient exhaled gases to the exhaled gas port, and the reduction of the activation pressure allows the bellows members to move the poppet face away from the valve seat and out of engagement with the valve seat to permit flow of patient exhaled gases to the exhaled gas port, thereby controlling the flow of patient exhaled gases from the valve.

Abstract: A bubble continuous positive airway pressure device has a container having an inner space, an inner conduit mounted in the inner space for conducting an airflow, an outer conduit mounted around the inner conduit, a rack longitudinally mounted on the outer conduit, a gear disposed in the inner space and meshed with the rack, and a knobt. The inner conduit has an aperture. The outer conduit is longitudinally slidable relative to the inner conduit, and has at least one through hole connected with the aperture. The knob drives the gear to rotate and the gear drives the rack, so as to drive the outer conduit to slide downward or upward in the inner space. The bubble continuous positive airway pressure device prevents dust and bacteria in the ambient environment from polluting the liquid in the container when adjusting gas pressure, so as to ensure the patients' health.

Abstract: The present disclosure generally relates to systems and methods for delivery of therapeutic gas to patients, in need thereof, receiving breathing gas from a high frequency ventilator using at least enhanced therapeutic gas (e.g., nitric oxide, NO, etc.) flow measurement. At least some of these enhanced therapeutic gas flow measurements can be used to address some surprising phenomenon that may, at times, occur when wild stream blending therapeutic gas into breathing gas a patient receives from a breathing circuit affiliated with a high frequency ventilator. Utilizing at least some of these enhanced therapeutic gas flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives can at least be more accurate and/or under delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

Abstract: A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber. When the valve is actuated, the aqueous solution flows from the reservoir through the internal chamber and into the reaction chamber. This flow washes the catalyst into the reaction chamber along with the aqueous solution. The solution and catalyst mix with the peroxide adduct and cause an oxygen-generating reaction.

Abstract: Described are systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors atypical use in systems for delivering therapeutic nitric oxide gas to a patient. The long term sensitivity drift of catalytic type electrochemical gas sensors may be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can be used to reduce the amount of times the sensor goes offline.

Abstract: A method and apparatus to identify the source of oxygen delivery failure to a patient. The apparatus comprises a pressure sensor to detect a patient's breathing pressure and ambient pressure, an oxygen flow analyzer to measure oxygen flow to the patient, and a processor to analyze the breathing pressure values, ambient pressure value, and oxygen flow rate values. When the oxygen flow rate value is greater than a predetermined threshold value, the processor is programmed to compare the breathing pressure values to the ambient pressure value and output an apnea alarm or an oxygen delivery device displacement alarm.

Abstract: Systems (100) and methods (300) for controlling coughing by subjects (106) control the opening and closing of a valve (12) (as well as partially opening and/or partially closing) to establish and disestablish a fluid communication between the airway of the subject and atmospheric pressure. The valve is opened and closed more than once during individual exhalations by the subject. Control of the valve is adjusted based on a pressure level in or near the airway of the subject.

Abstract: An inhalation device including a housing, which encloses a liquid reservoir in which the liquid is stored before discharge, and an applicator head with a nebulization chamber and an applicator piece connected thereto, wherein the applicator piece is designed either as a mouthpiece, to be received in the mouth of a patient, or as an inhalation mask, to sealingly cover the mouth, the nose, or the mouth and the nose. The inhalation device furthermore has a discharge channel which connects the liquid reservoir to the applicator head. The inhalation device includes at the end of the discharge channel, a nozzle plate with a large number of nozzle openings which serve to generate an inhalation mist and through which the liquid from the liquid reservoir is conveyed into the nebulization chamber.
