Aerosol delivery device
First Claim
1. An aerosol delivery system comprising:
- a body having a first end and a second end;
the first end comprising an opening having a rotatable fitting for connecting directly with a medical gas supply wall outlet;
the second end connected with a proximal end of a length of multi-lumen tubing;
a liquid reservoir channel and a gas channel positioned in the body between the first and second ends, the liquid reservoir channel configured to hold a liquid and positioned in parallel with the gas channel, wherein the gas channel is separated from the liquid reservoir channel by a dividing wall;
a one-way filling port positioned on the body to permit injection of a liquid into the liquid reservoir channel adjacent the first end of the body, wherein when the rotatable fitting is attached to the medical gas supply wall outlet on a wall, the one-way filling port is positioned at an angle away from the wall.

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 μm.
