An assembly structured for concurrent irrigation and aspiration of a nasal cavity including a housing having a supply container disposed therein for the removable retention of irrigating fluid. A nasal applicator comprises first and second passages respectfully structured to deliver irrigating fluid
An assembly structured for concurrent irrigation and aspiration of a nasal cavity including a housing having a supply container disposed therein for the removable retention of irrigating fluid. A nasal applicator comprises first and second passages respectfully structured to deliver irrigating fluid to the nasal cavity and concurrently remove waste fluid therefrom. An activating assembly includes a plunger biased into a continuous pressure applying, dispensing relation to the irrigating fluid and a valve assembly is selectively disposable into an open position facilitating fluid communication between the supply container and the applicator for the delivery of the irrigating fluid therethrough into the nasal cavity. The activating assembly is further structured to create a negative pressure within the chamber which communicates with the second passage of the applicator to facilitate delivery of the waste fluid therefrom along a path of travel to an interior of the chamber.

An assembly as recited in claim 1 wherein said applicator is dimensioned to be inserted into the nasal cavity through each nostril independent of the other. 5. An assembly as recited in claim 1 further comprising a drain structure formed in said housing and disposable in an emptying orientation, said emptying orientation defining fluid communication between said second chamber section and an exterior of said housing and an emptying of waste fluid from said interior chamber through said drain structure. 6. An assembly structured for concurrent irrigation and aspiration of a nasal cavity, said assembly comprising: a housing including a supply container disposed therein,said supply container including an interior chamber comprising a first chamber section and a second chamber section, said first chamber section structured to removably retain irrigating fluid therein,an applicator connected to said housing; at least a portion of said applicator dimensioned and configured to be inserted in the nasal cavity,said applicator comprising a first passage and a second passage; said first passage at least partially defining a flow path of irrigating fluid from said first chamber section into the nasal cavity; said second passage at least partially defining a path of travel of a drained waste fluid from the nasal cavity into said second chamber section,a valve assembly disposable on the housing between an open position and a closed position; said open position defining a path of fluid flow from said first chamber section to said applicator and the nasal cavity,an activating assembly comprising a drive member and a biasing structure disposed within said interior chamber and cooperatively structured with said valve assembly to force the irrigating fluid from said first chamber section through said applicator, when said valve assembly is in said open position,said drive member movably disposed in fluid sealing relation between said first and second chamber sections; said biasing structure disposed within said second chamber section in biased, pressure applying and dispensing relation to the drive member and the irrigating fluid within said first chamber section,said movement of said drive member into driving relation to the irrigating fluid comprising a concurrent reduction of said first chamber section and expansion of said second chamber section and a concurrent negative pressure being formed in said second chamber section and said path of travel; andsaid concurrent negative pressure resulting in aspiration of the drained waste fluid, via said path of travel, from the nasal cavity into said second chamber section concurrent to delivery of the irrigating fluid from said first chamber section, via said flow path, to the nasal cavity when said applicator is disposed in the nasal cavity. 7. An assembly as recited in claim 6 wherein said path of travel further extends in fluid communication with and between said second passage and said second chamber section. 8. An assembly as recited in claim 7 wherein said path of travel is at least partially disposed between an interior surface of said housing and an exterior surface of said supply container. 9. An assembly as recited in claim 6 wherein said drive member comprises a plunger movably disposed within said interior chamber in substantially fluid sealing relation with interior surfaces of said supply container; said biasing structure and said plunger disposed and structured to force the irrigating fluid from said interior chamber to and through said applicator when said valve assembly is in said open position. 10. An assembly as recited in claim 9 wherein said concurrent negative pressure formed within said path of fluid flow and said second chamber section upon movement of said plunger within said interior chamber and forced flow of the irrigating fluid from said first chamber section to and through said flow path. 11. An assembly structured for concurrent irrigation and aspiration of a nasal cavity, said assembly comprising: a housing including a supply container disposed therein,said supply container including an interior chamber comprising a first chamber section and a second chamber section, said first chamber section structured to removably retain irrigating fluid therein,an applicator connected to said housing in fluid communication with said interior chamber,said applicator at least partially disposable within the nasal cavity and structured for concurrent passage of irrigating fluid into and waste fluid out of the nasal cavity,an activating assembly including a plunger and a biasing structure disposed within said chamber, said plunger movably disposed within said interior chamber in pressure applying, dispensing relation to the irrigating fluid,said plunger movably disposed within said interior chamber in fluid sealing relation between said first and second chamber sections; said biasing structure disposed within said second chamber section in biased, pressure applying and dispensing relation to the plunger and the irrigating fluid within said first chamber section,said activating assembly further comprising a valve assembly connected to said housing and selectively disposable between a closed position and an open position; said open position defining said fluid communication of said applicator with at least said first chamber section and the irrigating fluid therein,said movement of said plunger within said interior chamber into pressure applying relation to the irrigating fluid comprises a concurrent reduction of said first chamber section and expansion of said second chamber section and a concurrent negative pressure being formed in said second chamber section, andsaid concurrent negative pressure resulting in aspiration of the waste fluid from the nasal cavity into said second chamber section concurrent to delivery of the irrigating fluid from said first chamber section to the nasal cavity, when said applicator is disposed in the nasal cavity. 12.
