DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0040] As clearly represented in the accompanying drawings, the present invention is directed to an irrigation assembly generally indicated as 10, structured for concurrent irrigation and aspiration or drainage of an individual's nasal cavity and passages in order to promote and maintain better nasal hygiene by effectively cleaning, disinfecting and/or medicating the nasal cavity and passages.

[0041] More specifically, the irrigation assembly 10 comprises an outer housing 12 having an at least partially hollow interior 14. The interior 14 is sufficiently dimensioned and configured to include a supply container 16 disposed therein. Dependent upon the preferred embodiment and/or practical application of the irrigation assembly 10 being utilized, the supply container 16 may be fixedly/permanently and/or removably disposed within the interior 14. Moreover, the supply container 16 includes a chamber 18 disposed on the interior thereof, wherein at least a portion of the interior chamber 18 is structured to temporarily or removably retain an irrigating fluid 20 therein. The irrigating fluid 20 may be initially stored and eventually dispensed from what may be referred to as a first or upstream chamber section 18. Also, a second or downstream chamber section 18 is disposed on the opposite side of a drive member or plunger 22, in fluid segregated relation to the upstream section 18. The terms upstream and downstream 18 and 18 respectively refer to the direction of movement of the drive member or plunger 22 as the irrigating fluid 20 is being dispensed from the irrigation assembly 10. Therefore the plunger 22 is movably disposed within the interior chamber 18 in fluid sealing relation to the interior surfaces thereof.

[0042] For purposes of clarity and as will be explained in more detail with regard to the schematic representation of FIG. 4, the plunger 22 is associated with a biasing structure 24 which maintains the drive member or plunger 22 in a continuous, dispensing, pressure applying relation to the irrigating fluid 20. The pressure applying relation of the drive member or plunger 22 results in the forced flow and eventual dispensing of the irrigating fluid 20 from the first or upstream section 18 of the chamber 18, as indicated by the directional arrow 100. Accordingly, as the plunger 22 is forced to move within the interior of the chamber 18, due to the biasing influence of the biasing member 24, the irrigating fluid 20 will be forced to flow from the first or upstream section 18 in the direction corresponding to arrow 100.

[0043] Moreover, movement of the plunger 22 within the chamber in a manner causing the forced flow 100 will result in the volume of the first section 18 being diminished as the irrigating fluid 20 is dispensed. Concurrently, the volume of the downstream or second section 18 of the interior chamber 18 will expand or increase, as the plunger 22 causes the forced flow 100 of the irrigating fluid 20. As a result, a negative pressure will be at least initially formed within the second section 18 due to a venting structure 50 facilitating the passage of fluid into the downstream or second section 18, from the interior of the housing 12. Further, the plunger 22 and the biasing structure 24 may be considered a part of an activating assembly which includes structural and operative features facilitating the dispensing or forced flow 100 of the irrigating fluid 20 from the interior chamber 18 and more specifically from the first or upstream section 18 thereof.

[0044] Additional structural and operative features of the irrigation assembly 10 include an applicator generally indicated as 30. Applicator 30 is selectively disposable in fluid communication with the interior chamber section 18 as well as the irrigating fluid 20 initially stored or retained therein. Selective establishment of the fluid communication of the applicator 30 and the interior chamber 18 is accomplished through the selective manipulation of a valve assembly generally indicated as 40. In more specific terms, the valve assembly 40 includes an activating button or exteriorly accessible member 42. A valve stem 44 is connected to the button or member 42 which may be moved inwardly by applying a sufficient pushing or other appropriately directed force thereto. The valve assembly 40 may be initially disposed in a closed position as represented in FIG. 3, wherein fluid communication with the irrigating fluid 20 and the interior chamber 18 is blocked. As a result, the irrigating fluid 20 will be prevented from exiting the first chamber section 18 due to the position of a closed end 44 of the valve stem 44. However, a selective inward orientation or pushing of the member 42 will result in the valve assembly being in an open position. Such an open position of the valve assembly 40 has a valve port 46 of the valve assembly 40 being disposed in aligned, fluid communication with a delivery port 48 formed in the corresponding end of the supply container 16. Also the alignment of the valve port 46 and the delivery port 48 will serve to further establish fluid flow between the irrigating fluid 20 on the interior of the first or upstream section 18 and the inlet port 32 of the applicator 30.

[0045] As should be apparent, the resistance of a liquid to being compressed will result in the irrigating fluid 20, which will typically be in the form of a liquid, being maintained under a constant pressure as long as the valve assembly 40 is in the closed position. More specifically, while the valve assembly 40 is closed, the biasing structure 24 continuously forces the plunger 22 into pressure applying, driving relation to the irrigating fluid 20 in the form of a liquid. Accordingly, when the valve assembly 40 is subsequently disposed into the open position, the continuous force exerted on the irrigating fluid 20 by the plunger 22 and biasing structure 24 will result in the forced flow 100 of the irrigating fluid 20 from the upstream or first section 18 to the applicator 30, as set forth herein. Therefore, the irrigation assembly 10 can be made available with the irrigating fluid 20 pre-loaded into the first chamber section 18 and maintained therein under a sufficient pressure, while the valve assembly 40 is in the closed position, to eventually dispense the irrigating fluid from the first chamber section 18. Therefore, when positioned for use, relative to the nasal cavity being irrigated, the irrigating fluid 20 will be automatically dispensed from the irrigation assembly 10, merely by disposing the valve assembly into the open position.

[0046] As represented in FIG. 3A, additional structural and operative features of one preferred embodiment of the applicator 30 include an outer tube or conduit 34 and an inner tube or conduit 36 disposed in coaxial, concentrically surrounded relation by the conduit 34. As such, the applicator 30 includes a first passage 37 extending along the interior of the inner tube or conduit 36. A second passage 38 is defined between the interior surface of the outer tube or conduit 34 and the exterior surface of the inner tube or conduit 36. As should be apparent from a review of the included Figures, the first passage 37 is disposed in direct fluid communication with the upstream or first section 18 of the chamber 18 as well as the irrigating fluid 20 therein, when the valve assembly 40 is in the aforementioned open position. Therefore, upon at least partial insertion of the applicator 30 into the nasal cavity, such as independently through each or a selected one of the open nostrils, both the first and second passages 37 and 38 will be at least partially disposed within and communicate with the interior of the nasal cavity. Furthermore, as illustrated in FIG. 1, a tip cover 35 is preferably provided as part of the applicator 30 to effectively seat the applicator 30 within the nostril, and also to preferably create an effective seal to prevent leakage and/or maximize the effects of any drainage or suction. In this regard, the tip cover 35 (see FIG. 1) preferably has a tapered configuration to provide for the effective insertion and seating within the nostril, and can be formed of a rigid material in view of the flexibility of the nostril to contour around the tip cover 35, and/or it may be partially resilient to provide some comfort and contouring.

[0047] The applicator 30 will then be properly positioned to begin and continue irrigating of the nasal cavity. When so positioned, the valve assembly 40 may then be disposed into the open position thereby creating the forced flow 100 of irrigating fluid 20 from the interior of the upstream section 18 and successively through the outlet port 48, valve port 46 and inlet port 32, into and through the passage 37, and out of the nozzles 39 into the interior of the nasal cavity. The forced flow 100 will be continuous due to the fact that the drive member or plunger 22 is under a continuously exerted dispensing, pressure applying force by the biasing structure 24.

[0048] While the biasing structure 24 may assume a variety of different structures and/or dispositions, one embodiment, as represented in the accompanying Figures, comprises it being disposed between a corresponding end 12 of the housing 12 and a correspondingly disposed surface 22 of the plunger 22. The physical characteristics of the biasing member 24 will be sufficient to force the plunger 22 along the length of the interior portion of the first or upstream section 18 of the interior chamber 18, thereby facilitating a dispensing of the irrigating fluid 20 therefrom into and through the applicator 30.

[0049] As emphasized, the structural and operative features of the irrigation assembly 10 are such as to accomplish an aspiration and/or drainage of the waste fluid from the nasal cavity concurrent to the delivery of irrigating fluid 20 thereto. Such concurrent aspiration and/or drainage is facilitated by a creation of an at least partial vacuum or negative pressure within the second or downstream section 18 of the interior chamber 18, as the plunger 22 moves along the length of the upstream section 18.

[0050] Due to the provision of the venting structure 50, the interior of the chamber 18 is partially enclosed concurrently to the first and second chamber sections 18 and 18 being disposed in fluid segregating relation to one another by the plunger 22. As a result, movement of the plunger 22 in a direction towards the valve assembly 40, causing the forced flow of fluid 100, serves to diminish the volume and fluid content of the interior of the first or upstream section 18 concurrent to an increase or expansion of the volume of the second or downstream section 18. Of course, it is understood that other configurations, such as, including a flexible bladder segregated into the first and second chambers by a moveably clamping and/or segregating element, could also be effective to maintain the functionality of a single larger volume segregated into cooperative chambers that vary in size while maintaining the isolation of the irrigation fluid from contamination.

[0051] As indicated in FIGS. 1 and 4, the venting structure 50 is preferably formed along the end of the supply container 16 which is opposed to the location of the valve assembly 40. Such venting structure 50 may include at least one or a plurality of individual, spaced apart vents, which are disposed in fluid communication between the interior of the downstream chamber section 18 and the interior 14 of the housing 12. More specifically the housing 12 and the supply container 16 are cooperatively dimensioned and configured to create a space 14 between the interior surface of the housing 12 and the exterior surface of the supply container 16. Such space 14 may be disposed in at least partially surrounding relation to the exterior of the supply container 16 as well as being disposed in fluid communication with the second passage 38 in the applicator 30 (see FIG. 3) by means of a connecting conduit or passage 54.

[0052] Therefore, the space 14 may at least partially define a path of travel of the aspirated waste fluid as it passes from the interior of the nasal cavity, through the second passage 38, along the interior of the connecting conduit or passage 54 into the space 14 and eventually into and through the vent structure 50 into the interior of the second or downstream section 18 of the chamber 18. For purposes of clarity, the flow and/or at least partial path of travel of the aspirated waste fluid is schematically represented by directional arrow 102 as it leaves the second passage 38 of the applicator 30 and begins to enter the portion of the path of travel defined by the space 14 between the interior and exterior surfaces of the housing 12 and the supply container 16 respectively. Moreover, the at least partial vacuum or negative pressure created or generated within the second or downstream section 18 of the chamber 18, by the movement of the drive member or plunger 20 as it causes the forced flow 100 of irrigating fluid 20, will be sufficient to create a pulling force which further facilitates the aspiration of the waste fluid from the nasal cavity concurrent to the introduction and of the irrigating fluid 20 into the nasal cavity through the first passage 37. The amount of aspirated waste fluid passing into the interior of the second section or downstream section 18 will be sufficient, due at least in part to the created vacuum or negative pressure, to empty the waste fluid from the nasal cavity in an effective manner.

[0053] As set forth above, the various preferred embodiments of the irrigation assembly 10 of the present invention may be structured as a single use, disposable device, wherein all or at a predetermined portion of the pre-stored or pre-loaded irrigating fluid will be utilized for a single application of the irrigating fluid into each nostril. In contrast, the housing 12 and the supply container 16 may be made larger, such that the irrigation assembly may be used for multiple applications. As should be apparent, repeated use of the irrigation assembly 10 would necessitate that the initially stored quantity of the irrigating fluid be sufficient to permit its repeated use. In this latter embodiment, manipulation of the aforementioned valve assembly 40 and drive member 22 will regulate a forced flow or dispensing of an intended or predetermined amount of the irrigating liquid from the interior of the upstream portion 18 of the chamber 18 of the supply container 16, as the valve assembly 40 is selectively moved between the closed and open positions. In order to assure a proper or intended amount of irrigating fluid is administered to each nostril, the irrigation assembly 10 may be structured to include audible or visual alarm. Such an alarm or other appropriate indicating capabilities may be time based or volume based, wherein an adequate audible or visual signal would be conveyed to a user, based respectively on the time duration of each administration of irrigating fluid or the quantity of irrigating fluid being administered.

[0054] After multiple applications and subsequent to dispensing all of the irrigating fluid, the irrigation assembly 10 may be structured to replace the supply container 16 with a new, pre-filled supply container (not shown). As should be apparent, prior to refilling or attaching a new supply container 16 the housing 12 will be thoroughly cleaned and the accumulated waste fluid and material will be removed. In the alternative, the original supply container may be refilled with an appropriate irrigating fluid, such as by the provision of an access port formed on the housing and/or supply container. With both of the above indicated reusable embodiments, the entire irrigation assembly may be discarded as desired or after a predetermined number of uses.

[0055] Additional preferred embodiments of the present invention include structural variations or modifications of the applicator 130 as represented in the embodiment of FIGS. 5, 5A and applicator 130 as represented in the embodiment of FIGS. 6 through 11. Both of the applicators 130 and 130 include a plurality of dispensing nozzles 140 formed in the outer or distal end 142 of each of the applicators 130 and 130. As clearly represented in FIGS. 8 and 9, each of the dispensing nozzles 140 are disposed at preferably an angle of between 5-45 degrees, relative to the longitudinal center axis of the corresponding applicator 130 or 130, with a preferred angle of generally about 15 degrees. The irrigating liquid will be dispensed concurrently from each of the dispensing nozzles 140. As such, the aforementioned angular orientation of the dispensing nozzle 140 defines a predetermined dispensing pattern resulting in a substantially or at least partially swirling or vortex flow of the irrigating fluid as it exits the nozzles 140 and impinges onto the interior surfaces of the nostril in which the applicator 130, 130 is inserted. Such a vortex configuration of the dispensing pattern and/or flow of the irrigating fluid will cause a thorough cleaning of the interior surfaces of the nostril. In addition the swirling or vortex flow will result in a channeling or directing of the irrigating fluid, into a central portion of the nostril. As a result, the waste fluid and dislodged waste material will be more effectively retrieved by the applicator, as the concurrent irrigation and aspiration/drainage of the nostril is performed.

[0056] In the embodiment of FIGS. 5 and 5A, the dispensing nozzles 140 are disposed in communicating relation with a first passage 137, functionally equivalent to the first passage 37, represented in FIGS. 3, 3A and 4. As such, the irrigating liquid or fluid passes through the first passage 137 from the upstream chamber 18 and will exit through the dispensing nozzles 140 into the nostril engaged by the applicator 130. Moreover, as represented in FIG. 5A the second passage 138 is concentric to and located exteriorly of the first passage 137 and between the exterior surface of the inner conduit 136 and the inner surface of the outer conduit 134. Accordingly, similar to the embodiment of FIGS. 3, 3A and 4, a first passage 137 is disposed on the interior of the inner conduit 136 and in direct fluid communication with each of the plurality of dispensing nozzles 140. The drainage or aspiration of the waste fluid, once having performed a cleaning action on the interior surfaces of the nostril, will then return to the interior of the housing 12 by virtue of flow along the second passage 138.

[0057] In contrast, the applicator 130 of the embodiment of FIGS. 6 through 11 includes the first passage 137 again being disposed in direct fluid communication with each of the dispensing nozzles 140 and with the upstream chamber or section 18 of the supply container 16 through the valve assembly 40. However, in the applicator 130 the first passage 137 is located exteriorly of a second passage or drain passage 138. The drain and/or second passage 138 is disposed interiorly and coaxially to the center longitudinal axis of the applicator 130. As indicated above, the vortex flow pattern of the irrigating fluid, as it issues and/or is dispensed from the angularly oriented dispensing nozzle 140, will result in a center channeling or directing of the irrigating fluid or waste fluid subsequent to an engaging of the interior surfaces of the nostril. As such, the centrally located second or drain passage 138 is disposed in an interior position within the inner conduit 136. This inner or substantially centralized location of the second passage 138 facilitates the collection, drainage and aspiration of the irrigating fluid and waste material (waste fluid) dislodged or collected from the interior of the nostril to the interior of the housing, along the channel 14, as set forth above with regard to the embodiments of FIGS. 3 and 4. As also clearly represented, the drain passage or second passage 138 includes an open outer or distal end 138 which further facilitates the drainage, aspiration and/or removal of the irrigating fluid, once having performed its cleaning, disinfecting and/or medicating function of the interior of the nostril being treated.

[0058] Additional structural features include a mounting or connecting end generally indicated as 150, which may assume a variety of different dimensions and configurations to facilitate the attachment of the applicators 130 or 130 to the remainder of the components of the irrigating assembly 10. Such attachment of the applicators 130 and 130 will establish their fluid communication with the upstream chamber section 18, valve assembly 40 and interior passage 14 of the housing 12.

[0059] Yet additional structural and operative features of one or more preferred embodiments may include a drain structure 60 including one or more emptying ports 60, as represented in FIG. 4. In an embodiment incorporating the drain structure 60, the irrigation assembly 10 may be repeatedly reused. More specifically, once the aspirated or drained waste fluid has been collected into the downstream section 18 of the chamber 18, the collected waste fluid may be removed or emptied from the housing 12 and/or chamber section 18 to facilitate the repeated use of the irrigation assembly 10, after proper cleaning. Accordingly, the drain structure 60 including the one or more emptying ports 60 may be located in the bottom 12, or other appropriate portion of the housing 12, in fluid communication with the interior of the downstream section 18 of the chamber 18 in which the waste fluid is collected. Further, the opening of the emptying ports 60 of the drain structure 60 will allow the collected waste fluid to empty from the interior of the housing or downstream section 18 of the chamber 18, such that the irrigation assembly can be repeatedly reused, as set forth above.

[0060] Accordingly and as set forth above, the irrigation assembly 10 may be a single use, disposable device or be structurally modified to facilitate multiple or repeated uses by the replacement of supply containers 16, pre-loaded with irrigating fluid. Alternatively, after emptying the waste fluid, such as through the drain structure 60, the supply container 16 and chamber 18 may be refilled from an external reservoir that hygienically maintains fluid, prior to refilling and use.

[0061] Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
