Abstract
A nebulizer is provided to atomize a liquid medication for rapid delivery of an aerosol spray to a user via inhalation. The nebulizer includes a jar having a compressed gas passage. A jet cooperates with the jar and has a jet orifice through which the liquid medication and the compressed gas are discharged to form an aerosol flow. The cap is connected to the jar to define an inner chamber. The cap includes an entrainment port for ambient room air, and a chimney in fluid communication with the entrainment port and the inner chamber. A deflector base having an impingement member is located adjacent to the entrainment chimney and is spaced below an opening thereof by a predetermined distance to provide a flow of the ambient room air to be entrained in the aerosol flow in order to enhance nebulization speed while maintaining a desired aerosol particle size.
