A self-contained, high capacity nebulizer, having automatic mixing and temperature control features is provided. The nebulizer may be adapted for use in conjunction with mechanical respirators, ventilators, or breathing machines, and for this purpose will use electrical signals generated by or received from the respirator to automatically control the nebulizing and mixing functions such that nebulization occurs intermittently, that is, only during the inhalation phase of the respiratory function. The nebulizer may also be adapted for manual and/or continuous use by providing an external electrical signal generator to manually control the nebulization and mixing functions. |

DETAILED DESCRIPTION The present invention provides a self-contained, high capacity, intermittent nebulizer for use with a mechanical respirator.
In one embodiment, the present invention provides a nebulizer for use with mechanical respirators which use electrical signals to control the breathing cycle.
The nebulizer of this embodiment uses the existing electrical signals from the mechanical respirator to synchronize aerosol generation and initiation of the inhalation cycle to insure that a high concentration of respirable aerosol is only provided during the inhalation phase of the breathing cycle.
Nebulization is obtained in this embodiment using the premixed oxygen-enriched air provided at high pressure to the respirator.
Automatic temperature regulation and stirring of the liquid medication is optionally provided to preclude the concentration of the medication due to separation or settling.
Finally, a large volume reservoir is provided to eliminate the need for refilling during lengthy treatment protocols.
In another embodiment, the present invention provides a nebulizer with nebulization and mixing functions which uses electrical signals from an external power source to control the nebulization and mixing functions.
In this embodiment, manual control of the nebulizer is obtained and can be used to provide medicinal aerosols continuously or on demand.
In yet another embodiment, the present invention provides a method for delivering medicinal aerosols to a user over extended periods of treatment .
