20090301495 | NASAL CONTINUOUS POSITIVE AIRWAY PRESSURE DEVICE AND SYSTEM - An nCPAP device including a generator body defining first and second fluid flow circuits each including a tube and first and second nozzles. The tube defines a passageway forming an axial centerline. The first and second nozzles are associated with the tube and each defines an inlet and an outlet. The inlets are open to a fluid supply, whereas the outlets are open to the passageway. Each nozzle is adapted to emit a fluid jetstream from the outlet along a flow direction axis. The nozzles are arranged such that the flow direction axes are non-parallel relative to each other and relative to the axial centerline. This configuration readily induces vortex shedding during an expiratory phase, thus facilitating jet fluid flow disruption and reducing a patient's work of breathing. | 12-10-2009 |
20100108073 | NASAL INTERFACE PRONG DEVICE - 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. | 05-06-2010 |

20140166011 | NEBULIZER MOUTHPIECE FOR REDUCING DRUG LOSS - A method for reducing a loss of medication from a nebulizer includes the steps of entraining a liquid medication into a first flow of a pressurized gas into a nebulizer chamber and also entraining an additional amount of the liquid medication into a second flow of ambient air drawn into the nebulizer chamber through an opening when a patient inhales through the nebulizer chamber. When the patient exhales, a portion of the exhaled breath is directed into the outlet of the nebulizer chamber, thereby increasing a backpressure within the outlet and substantially stopping the second flow of ambient air into the nebulizer chamber, thereby decreasing the amount of medication lost to the ambient environment while the patient is not inhaling. | 06-19-2014 |
