  • System for providing flow-targeted ventilation synchronized to a patient's breathing cycle
    Patent number: 8015974
    Abstract: An open system provides breath-synchronized, flow-targeted ventilation to augment respiration by a self-breathing patient. A sensor detects a physical property of a patient's respiratory cycle. A processor monitors the sensor and controls a gas source to deliver oxygen-containing gas through a tube extending into the patient's airway with the flow rate varying over each respiratory cycle in a predetermined non-constant waveform synchronized with the respiratory cycle to augment the patient's spontaneous respiration. Gas is delivered at a flow rate sufficient to significantly mitigate the airway pressure the patient must generate during spontaneous breathing and thereby reduce the patient's work of breathing.

    Abstract: Systems and methods may include a gas source, a gas delivery circuit, and a nasal interface allowing breathing ambient air through the nasal interface. A gas flow path through the nasal interface may have a distal gas flow path opening. A nozzle may be associated with a proximal end of the nasal interface a distance from the distal end gas flow path opening. At least a portion of an entrainment port may be between the nozzle and the distal end gas flow opening. The nozzle may deliver gas into the nasal interface to create a negative pressure area in the gas flow path at the entrainment port. The nasal interface and the nozzle may create a positive pressure area between the entrainment port and the distal end gas flow path opening. Gas from the gas delivery source and air entrained through the entrainment port may increase airway pressure or lung pressure or provide ventilatory support.

  • Nasal interface prong device
    Patent number: 7987850
    Abstract: An infant nasal interface prong device for use with an nCPAP system. The device includes first and second nasal prongs and a base. Each prong includes a bellows segment, a tip, and a lumen. The tip extends from the bellows segment to a tip end and is adapted for insertion with an infant's naris. The lumen extends through the tip and the bellows segment. In an undeflected state, a central axis of the lumen along the bellows segment is transversely offset from the lumen axis at the tip end. The base is connected to each of the nasal prongs and is adapted for coupling to a CPAP generator. The bellows segment renders the corresponding prong highly flexible relative to the base. The offset positioning of the tip end promotes desired positioning of the base/CPAP generator, relative to the patient and more closely conforms to the expected nasal anatomy.

The device comprises a check valve (20, 20?) and a cylindrical or conical airtight tube (30, 32?, 33, 34, 34?/36?) with an opening at each end. The valve is so fastened or connected to the tube at one end as to form a one-way air channel/passage. The tube conforms to or fits the interiors of different nostrils air-tightly in a variety of ways (32?, 34, 38, 40, 34?, 40?, 46). A pair of such devices can be connected with a flexible strip (42) or a band (44). Inserting the device into the nostril, a wearer can inhale through the nose but has to exhale through the mouth. This reduces the wearer's appetite for food and slows down eating. The wearer can easily remove the device after eating or whenever desired.

  • METHODS, SYSTEMS AND DEVICES FOR NON-INVASIVE VENTILATION INCLUDING A NON-SEALING VENTILATION INTERFACE WITH A FREE SPACE NOZZLE FEATURE
    Publication number: 20110094518
    Abstract: A system for supplying ventilatory support may include a nasal interface configured to communicate with a patient's nose while allowing the patient to breathe ambient air directly without flowing through the nasal interface. A nozzle may be associated with the nasal interface at a distance from a nose. The nozzle may be connectable to the gas delivery circuit and the gas delivery source. The nozzle may be capable of delivering gas into the nasal passage by creating negative pressure area near the nozzle and a positive pressure area near the entrance to the nose. A combination of gas from the gas delivery source and air entrained from the gas exiting the nozzle may provide ventilatory support.

  • Breathing air filtration system
    Patent number: 7918224
    Abstract: A nasal air filtration device includes a pair of either planar or concave-convex filters, a support structure incorporating a pair of generally annular bases or sleeves for supporting the filters, and a bridge that couples the bases or sleeves to maintain them in a desired spaced-apart relation and to determine a desired angular relationship. The support structure is insertable into the nasal cavities to position the filters within corresponding nasal cavities. Flexible rims maintain the support structure and the filters in spaced-apart relation to the surrounding nasal wall. The rims conform to surrounding nasal tissue to form seals. The rims can be selectively inclined to facilitate insertion and resist accidental removal. In certain embodiments the device is combined with a filter that covers the mouth to provide an air filtration system.

  • Endotracheal tube
    Patent number: 7918227
    Abstract: An improved endotracheal tube is provided which is adapted to optimally and safely accommodate the nasopharyngeal airway during nasopharyngeal intubation. The endotracheal tube includes a body having a nasopharyngeal section adapted to sealably enclose and contain a spirally-wound coil longitudinally therealong. The nasopharyngeal section integrally transposes into a rigid section which extends longitudinally from the nasopharyngeal section and terminates at a lower end of endotracheal tube. The nasopharyngeal section with incorporated spirally-wound coil allows for multiple positioning of nasopharyngeal section about a face of a patient, thereby minimizing pressure sores, abrasions, and ulcerations, and further allows for quick, easy, and efficient surgical access to the nasopharyngeal airway without requiring removal of the endotracheal tube.

  • Applicators for a Nasal Cannula
    Publication number: 20110073116
    Abstract: The invention relates to an applicator for a nasal cannula, comprising a body (11) enclosing a hollow space (22). The applicator further comprises tube connections (20, 21) for supplying a respirable gas into the hollow space (22). The applicator further comprises prongs (18, 19) for administering the respirable gas into the nostrils of a person. A valve (15, 16, 17, 38, 42) is located in a wall of the body (11) so that respirable gas can flow from the outside through the valve into the hollow space (22), but not in the reverse direction. The invention further relates to an applicator having a top of sealing cones (23, 24), wherein the sealing cones (23, 24) may be provided with rim-shaped sealing lips on their side facing away from the body (11), which produce a tight seal with the inner wall of the respective nostril.

  • NASAL DEVICES FOR USE WHILE SLEEPING
    Publication number: 20110067708
    Abstract: Described here are devices for altering the flow of air in a respiratory cavity such as the mouth and nostrils of the nose. These methods and devices may be useful for affecting a physiologic benefit in patients suffering from a variety of medical diseases, particularly those that may benefit from “pursed-lip” breathing and non-invasive ventilation, such as COPD, heart failure, sleep apnea, and other medical disorders. The devices are typically removable devices that may be placed over or in a respiratory cavity to increase resistance to airflow within the respiratory cavity. Resistance to expiration may be selectively increased relative to inspiration. Removable oral and removable nasal devices are described. Oral and nasal devices that filter inhaled airflow of debris and allergens are also provided. A nasal device that increases patency of the nares is also provided.
