System for nasal irrigation

nasal irrigation device and method for irrigation of a nasal cavity are systems and methods for nasal irrigation in which a nasal irrigation device includes a saline solution source, an effluent receptacle, a nasal interface, a vacuum source, a fluid passage to communicate the saline source with the effluent receptacle through the nasal interface and the nasal cavity of the user, and a switch and valve assembly that selectively control the source of vacuum and the flow of saline solution through the fluid passage. the saline source vial is disposed relative to the device to provide gravitational induction of the saline solution to the nasal interface by coupling the user's nostrils to the device. a combination of gravitational induction and relative vacuum from an effluent receptacle generates a fluid flow for irrigation, cleaning and massaging a user's nasal cavity and ostium.
