Abstract
A medical nebulizer has a reservoir for medical liquid, a capillary nozzle having a proximal end for receiving liquid from the reservoir and a distal end connectable to an inspiration gas flow path to deliver liquid droplets into an inspiration gas flow, a pump for supplying liquid from the reservoir through the capillary nozzle, and a regulator for regulating the delivery of the liquid to a predetermined amount. The pump supplies the liquid in a continuous flow throughout the delivery of the predetermined amount and a stimulator, such as a piezoelectric vibrator, is provided for vibrating the distal end of the nozzle to stimulate droplet formation.
