    Abstract: An assembly for modifying patient airflow into a nasopharyngeal airway or trachea. A valve assembly having a valve seal is adapted to attach to an airflow generator. The valve seal is connected to and operable by a motor means. A controller circuit is connected to the motor means for operating the motor means incrementally such that pressurized air from the airflow generator continuously enters the interior feed tube from the inlet but passes out of the outlet only when the motor means causes the valve seal to move in relation to the exit tube to at least partially unblock the outlet such that the pressurized air is converted into a single, repeatable burst exiting the outlet. In one embodiment, instead of a motor, the valve assembly can include a shaft. A butterfly valve seal is attached to the shaft. A nickel titanium wire is in conductive communication with the shaft.

  • Publication number: 20140290659
    Abstract: The invention provides a reversing valve for reversing a fluid flow, comprising a valve housing defining a cylindrical chamber, at least four passage outlets being formed in the valve housing and opening into the cylindrical chamber, and further comprising a valve core being received rotatably and hermetically within the cylindrical chamber of the valve housing, at least two passages being defined in the valve core, wherein the passage outlets and the passages are arranged such that the reversing valve can reverse the liquid flow once every time that the valve core rotates through 90°. The invention also provides a high frequency oscillation airflow generator. According to the invention, the reversing frequency of the gas flow and thus the efficiency of the high frequency oscillation airflow generator are improved.

  • Patent number: 8844530
    Abstract: A medical device and method for combination lung ventilation and mucus clearance of a patient is disclosed. The medical device may be configured to provide lung ventilation with intermittent, on-demand mucus clearance, freeing the patient's mouth for activities of daily living such as when the patient is awake; and, in another configuration, the device can provide lung ventilation with automated mucus clearance, such as when the patient is sedated or asleep. The medical device may comprise a pressure generation source, a ventilation portion, and a mucus clearance portion. The mucus clearance portion may be separable from or separate from the ventilation portion such that the medical device is capable of maintaining lung ventilation with the mouth interface removed from the patient.

  • Patent number: 8844531
    Abstract: A respiration appliance, system, and method for supporting the airway of a subject as the subject breathes. The flow of gas from the lungs of the subject during exhalation is leveraged to provide support to the airway. In particular, a body that encloses one or more external orifices of the subject provides a resistance differential between inhaled gas flows and exhaled gas flows that supports the subject's airway.

  • Publication number: 20140276169
    Abstract: A nasal cannula which comprises a face piece comprising first and second nares which each communicate with a respective nostril of a patient. A septum divides the face piece into first and second flow paths such that the first flow path communicates with the first nare and the second flow path communicates with the second nare. A leading end of the first nare is configured to form a fluid barrier within a first nostril and facilitate only supplying an insufflation gas, via the first flow path, to the patient and prevent exhausting any of exhaust gas, of the patient, through the first nostril of the patient. A leading end of the second nare is configured to facilitate collecting some of the exhaust gas, from the patient, via the second flow path as well as exhausting a remainder of the exhaust gas out through a second nostril of the patient.

  • Publication number: 20140261429
    Abstract: An oxygen-supplying respirator requiring no electric power is provided. The oxygen-supplying respirator, which is driven not by electricity but by the oxygen supply pressure at an external oxygen supply end, includes an oxygen supply valve unit in communication with the oxygen supply end so as to turn on and off oxygen output therefrom. An inhalation/exhalation time setting valve unit is in communication between the oxygen supply valve unit and the oxygen supply end, receives the oxygen continuously supplied from the oxygen supply end, and outputs oxygen to the oxygen supply valve unit intermittently. Thus, the oxygen supply valve unit is driven to turn on the oxygen supply end intermittently and thereby enable intermittent oxygen output. The respirator can supply oxygen to a patient where there is no electricity.

  • Publication number: 20140251329
    Abstract: An entrainment port regulates the flow of gas and/or medicine into an inspiratory limb of a high frequency oscillatory ventilator (H0FOV) to improve the oxygen content of the air entering a patient. The entrainment port is connected to an oxygen source and uses entrained oxygen therefrom to enter the inspiratory limb. Medication and/or admixtures of medication, gas and/or humidification can be introduced through the entrainment port. The flow of entrained oxygen and the mean airway pressure is regulated by a plug valve. A check valve is calibrated to a pre-defined cracking pressure to open and allow the entrained oxygen into the inspiratory limb when negative pressure is asserted in the HFOV circuit by operation of the expiratory cycle of the HFOV.
