  • Patent number: 7059322
    Abstract: An airway adapter suitable for use with patients having low tidal volumes, e.g., neonates, which minimizes deadspace in the airway and promotes smooth flow of gases through the adapter. The adapter includes a first portion adapted to couple to a tubular adapter, such as an endotracheal tube adapter, and a second portion adapted to couple to a ventilation tube. A longitudinally compressible member is coupled to the first portion to minimize deadspace in the adapter. A portion of the compressible member resiliently contacts and seals against a tubular adapter upon assembly of the airway adapter therewith.

  • Patent number: 7059325
    Abstract: A vent valve apparatus (10) for use with a system for supplying breathable gas pressurised above atmospheric pressure to a human or animal. The apparatus (10) includes a gas washout vent (15), a vent valve (18) adapted to progressively restrict the flow area of the washout vent (15), and a pressure sensitive vent valve control means (20,22,23). The control means is adapted to progressively cause the vent valve (18) to restrict the flow area of the gas washout vent (15) in response to increases in the pressure of the gas supply, thereby substantially regulating the volumetric flow of gas and/or CO2 gas through the washout vent (15) over a range of gas supply pressures.

  • Patent number: 7051737
    Abstract: An endotracheal tube cleaning apparatus 10 which can be periodically inserted into the inside of an endotracheal tube 30 to shave away mucus deposits. In a preferred embodiment, this cleaning apparatus 10 comprises a flexible central tube 12 with an inflatable balloon 40 at its distal end. Affixed to the inflatable balloon are one or more shaving rings 70, each having a squared leading edge 72, to shave away mucus accumulations 60. In operation, the uninflated cleaning apparatus 10 is inserted into the endotracheal tube. The balloon 40 is then inflated by a suitable inflation device, such as a syringe 14, until the balloon's shaving rings are pressed against the inside surface of the endotracheal tube. The cleaning apparatus is then pulled out of the endotracheal tube to shave off mucus deposits.

  • Patent number: 7040314
    Abstract: Liquid aerosol formulations for generating aerosols include at least one high volatility carrier and a second component. In some embodiments, the liquid aerosol formulation is propellant free. An aerosol generating device generates an aerosol by passing liquid aerosol formulation through a flow passage heated to convert the liquid into a vapor, which is mixed with air to form an aerosol. In some embodiments, particles of the aerosol consist essentially of the second component. The aerosol generator can be incorporated in a hand held inhaler. The aerosol can be delivered to a targeted portion of the lung using the inhaler.

  • Patent number: 7040312
    Abstract: An oral airway consists of an elongate tubular member having a leading distal end and a proximal end, the leading distal end leading the elongate tubular member as it is inserted into the mouth and pharynx of a patient. An opening at the leading distal end of the elongate tubular member is inclined so that a posterior portion of the distal portion extends beyond an anterior portion of the distal end. A flexible tip portion extends distally beyond the opening to aid in insertion of the oral airway into the mouth and pharynx of a patient. The tip is configured to flex toward the opening as it abuts tissue within the mouth and pharynx of a patient.
