Patent number: 10130786Abstract: A method for reducing a loss of medication from a nebulizer includes the steps of entraining a liquid medication into a first flow of a pressurized gas into a nebulizer chamber and also entraining an additional amount of the liquid medication into a second flow of ambient air drawn into the nebulizer chamber through an opening when a patient inhales through the nebulizer chamber. When the patient exhales, a portion of the exhaled breath is directed into the outlet of the nebulizer chamber, thereby increasing a backpressure within the outlet and substantially stopping the second flow of ambient air into the nebulizer chamber, thereby decreasing the amount of medication lost to the ambient environment while the patient is not inhaling.Type: GrantFiled: January 21, 2016Date of Patent: November 20, 2018Assignee: Vyaire Medical Consumables, LLCInventors: Brian Pierro, Khalid Mansour, Christopher Varga
