Irrigation assembly
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.
1. An assembly structured for concurrent irrigation and aspiration of a nasal cavity, said assembly comprising:
a housing including a supply container,
said supply container including an interior chamber comprising a first chamber section and a second chamber section, said first chamber section structured to 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,
said path of travel extending in fluid communication with and between said second passage and said second chamber section and between an interior surface of said housing and an exterior surface of said supply container,
a valve 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,
a drive member disposed within said interior chamber and cooperatively structured with said valve to force the irrigating fluid from said first chamber section through said applicator, when said valve is in said open position,
said drive member configured to force the irrigating fluid from said first chamber section through said applicator as a result of movement of said drive member corresponding to a reduction of said first chamber section and an expansion of said second chamber section and a concurrent negative pressure being formed in said second chamber section and said path of travel; and
said 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.
2. An assembly as recited in claim 1 wherein said applicator is dimensioned to be inserted into the nasal cavity through each nostril, separately from and independent of the other nostril.
3. 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.
4. An assembly as recited in claim 1 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, and said assembly further comprises an activating assembly comprising a biasing structure structured to move said plunger to force the irrigating fluid from said interior chamber to and through said applicator when said valve assembly is in said open position.
5. An assembly as recited in claim 4 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.
