초록 ▼

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.

대표청구항 ▼

A nebulizer in combination with a mechanical respirator having an inhalation phase, an exhalation phase, a gas flow passageway and an external electrical signal source capable of generating a first electrical signal during said inhalation phase and a second electrical signal during said exhalation phase, or said first electrical signal during said exhalation phase and said second electrical signal during said inhalation phase, said nebulizer comprising: a housing containing a reservoir for holding a liquid to be nebulized and an air space above the reservoir for holding aerosol; an aerosol generator for generating said aerosol by nebulizing said liquid; a gas flow means for directing compressed gas from a compressed gas source to the aerosol generator, the gas flow means including a valve means for sensing said external electrical signal source and opening a conduit for the flow of compressed gas from the source of compressed gas to the aerosol generator to generate an aerosol when said first electrical signal is detected and for closing the conduit to the aerosol generator to stop the generation of aerosol when said second electrical signal is detected; a means for removably attaching said housing to said mechanical respirator, said attaching means adapted to communicate with the air space above said reservoir so that the aerosol in said airspace introduced into the gas flow passageway of said respirator when the housing is attached to said respirator, said attaching means further adapted to direct the aerosol generated to a position outside of the housing where it can be breathed in by a user when the housing is not attached to said respirator; and means for mixing the liquid in the reservoir.
