Abstract: An aerosol delivery system is disclosed that is a single-use (disposable) continuous nebulizer system designed for use with mechanically ventilated patients to aerosolize medications for inhalation with a general purpose nebulizer, or for connection with devices usable in endoscopic procedures. The system separates the liquid reservoir from the nebulization process taking place either at the adapter hub, where it fits into an endotracheal tube (ETT), or a gas humidifier, where the aerosol may treat a gas used in an endoscopic procedure, with a multi-lumen tube configured to nebulize liquid and air at its distal end. The refillable liquid reservoir is mounted away from the immediate treatment zone, avoiding orientation issues associated with other types of nebulizers having a self-contained reservoir. The system can produce aerosols having a wide range of droplet sizes, depending upon central lumen diameter, with values of MMAD that range from 4 to 30 ?m.

Abstract: A portable air pulse delivery device includes a housing and an air compressor having a motor disposed in the housing. The motor is operable at speeds between 1200 and 4800 rpm. The air compressor includes an air inlet and an air outlet. An untethered power source is disposed in the housing and is operably connected to the motor. An intake filter is disposed in the housing and is in fluid communication with the air inlet of the air compressor. An outlet port is coupled to the air outlet of the air compressor and is in communication with an exterior of the housing. A mouthpiece includes an inlet coupled to the outlet port and an outlet having a gas exit port. The air compressor is operative to produce an average gas flow rate of between about 2-3 L/min at the gas exit port at a pulsation frequency of between about 20 Hz to 80 Hz. A method for delivering air pulses to a mouth of a user is also provided.

Abstract: The present invention relates generally to an oral device, or mouthpiece, for delivering a fluid to the mouth or oropharynx of a user. In one embodiment, the oral device includes an intraoral portion, an extraoral portion, and an auxiliary support device that serves to stabilize the oral device. In various embodiments, the auxiliary support device may be configured with ear loops, a support band, a support frame and/or a support member. The intraoral portion generally includes at least one outlet port through which the fluid is delivered to the oral cavity or oropharynx. A method of dispensing a fluid using the oral device is also provided.

Abstract: An oral appliance for administering a stimulus, such as a substance, to the mouth of a user includes a flexible tube having an inlet portion, a first curved portion forming an ear loop connected to the inlet portion, a second curved portion forming a lip bend connected to the first curved portion, and an outlet portion extending from the second curved portion. Alternatively, a mouthpiece for delivering a substance to the mouth of a user includes a housing having an inlet portion, a riser portion extending upwardly from the inlet portion and a curved outlet portion. A flexible tube is coupled to the housing. A method of delivering a substance to a predetermined location in a user's mouth includes disposing a flexible tube between a row of teeth and an interior surface of a cheek. The flexible tube has an exit port positioned in a rear portion of the user's mouth.
