Drug nebulizer NebJet head with Venturi effect
A Venturi effect drug nebulizer head for use with most inhaler types, which achieves rapid drug delivery and shortens inhalation time.
(Venturi effect: The Venturi principle is that a liquid (or air) flowing in a tube accelerates when the tube narrows, according to Bernoulli's law, thereby reducing its pressure, and then slows down when the tube expands again, thereby reducing its pressure)
