Abstract
An improved nebulizer places a venturi in a rainfall chamber and in close proximity to or inside a patient's oral cavity. One or more medicine feed lines feeds the medicine to a location proximate to a venturi. The rainfall chamber contains a sump communicating with the venturi for collecting medication not delivered to the patient and for recycling that medication for delivery to the patient. A medicine receiver may be pre-filled with a standard unit dose of medication.
