Abstract
A nebulizer apparatus to atomize liquid solutions or suspensions. The nebulizer is typically used in conjunction with a breathing circuit to deliver atomized medicine to a patient. A housing with an opening covered by a thin mesh plate is supplied with the liquid to be nebulized on an “on-demand” basis. The mesh plate or liquid is vibrated at ultrasonic frequencies to atomize the liquid as it passes through the plate into breathing gases flowing through the breathing tube.
