Abstract
A nebulizer is improved by placing a flexible valve in the ambient air inlet tube. Inhalation suction and Venturi effect shut down the flexible valve in proportion to the strength of the inhalation. Thus, the same output flow rate is obtained even with variable strength inhalations. Medications can be properly administered by controlled inhalation flow rates.
