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 &#x3bc;m.

A dispenser includes a dispenser housing, a key device adapted to be mounted to a container and an indicating device. The key device is moveable between an engaged position wherein it is engaged with the indicating device and a disengaged position wherein it is disengaged from the indicating device. In other aspects, a resilient, flexible cap is fixedly secured to the dispenser housing and covers the container and prevents the valve stem from being disengaged from the dispenser housing. In another aspect, a dispenser housing has at least one guide and a connector has at least one arm having a catch portion. The arm is disposed through the at least one guide with the catch portion engaged with the guide such that the valve stem is prevented from being disengaged from the dispenser housing. In yet another aspect, a catch portion engages a ferrule portion of the container such the valve stem is prevented from being disengaged from the dispenser housing.
