Abstract

A powered irrigator for use in rinsing nasal cavities has a main body including a handle and a fluid reservoir detachably coupled to one another, an outlet nozzle extending from a top end of the handle, a pump mechanism operably coupled to a power source, and a switch operably coupled to the power source for turning the pump mechanism on and off. When the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle. The top of the handle can be angled relative to a longitudinal axis of the main body. The nozzle is removable from the top end and has a self-sealing structure to provide an enhanced fit within a user'"'"'s nostril.

Claims

wherein when the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle;

the pump has a cycle rate between 2,000 to 3,000 cycles per minute; and

the fluid exits the outlet nozzle at a pressure of approximately 5 pounds per square inch and at a flow rate between 500 to 600 milliliters per minute.

2. The irrigator of claim 1, wherein the reservoir and the handle are detachably connected by a bayonet latch mechanism.

3. The irrigator of claim 2, wherein the bayonet latch mechanism comprises a rotatable locking ring for establishing the detachable connection between the handle and the reservoir.

4. The irrigator of claim 3, wherein the rotatable locking ring rotates in a direction transverse to the longitudinal axis of the irrigator.

5. The irrigator of claim 4, wherein the locking ring is movably held in the reservoir.

6. The irrigator of claim 5, wherein the locking ring forms one of a tab or a slot, and the handle forms the other of the tab or the slot, and wherein the handle is secured to the reservoir upon aligning the tab and the slot and rotating the locking ring.

7. The irrigator of claim 5, wherein the locking ring comprises a flange at an exterior of the reservoir configured to slide between a locked and an unlocked position of the locking ring.

8. The irrigator of claim 2, wherein one of the reservoir or the handle comprises a tab and the other of the reservoir or the handle comprises a slot configured to secure with the tab, and the handle is secured to the reservoir upon aligning the tab and the slot and rotating the handle or reservoir with respect to the other.

9. The irrigator of claim 8, wherein the tab or the slot is formed by a bottom rim of the handle and the other of the tab or the slot is formed at an upper edge of the reservoir.

10. A powered nasal cavity irrigator comprising

a rigidly constructed main body comprising a handle and fluid reservoir, wherein the handle and the fluid reservoir are detachably connected to each other, and a top end of the handle comprises a portion being angled relative to a longitudinal axis of the main body;

an outlet nozzle extending from the top end of the handle at a substantially right angle relative to the angled portion of the top end;

a pump mechanism operably coupled to a power source; and

a switch operably coupled to the power source for turning the pump mechanism on and off, wherein the switch is arranged at an external surface of the handle;

wherein when the switch turns on the pump mechanism, fluid flows from the fluid reservoir into a first fluid coupling between the reservoir and the pump mechanism and into a second fluid coupling between the pump mechanism to the outlet nozzle; and

the pump has a cycle rate between 2,000 to 3,000 cycles per minute; and

the fluid exits the outlet nozzle at a pressure of approximately 5 pounds per square inch and at a flow rate between 500 to 600 milliliters per minute.

11. The irrigator of claim 10, wherein the reservoir is a substantially enclosed structure having a sealable inlet and an outlet projecting from a top surface of the reservoir.

12. The irrigator of claim 11, wherein the sealable inlet is formed in a sidewall aperture of the reservoir, and a reservoir cap removably connects to the sidewall aperture to seal the inlet.

13. The irrigator of claim 12, wherein the handle comprises a recessed tubular fitting at a bottom portion configured to mate with the reservoir outlet.

14. The irrigator of claim 11, wherein the reservoir and the handle are detachably connected by a locking ring movably held in the reservoir.

15. The irrigator of claim 11, wherein the reservoir comprises a sloped floor recessed from the top surface of the reservoir and a slit formed in a reservoir sidewall positioned at a bottom end of the sloped floor, wherein fluid escaping the reservoir outlet drains along the sloped floor and out the slit.

16. The irrigator of claim 10, wherein

the outlet nozzle comprises a tip with an aperture formed therein that is in communication with the second fluid coupling;

the outlet nozzle has a skirt wall extending downwardly and away from the aperture, an inner rim extending downwardly from the aperture and received by an upper end of the second fluid coupling, and an inner void space formed between the skirt wall and the inner rim; and

the skirt wall is operable to deflect into the inner void space upon engagement with a user'"'"'s nostril wall to form a self-sealing engagement with the user'"'"'s nostril wall.

17. The irrigator of claim 16, wherein the top end defines a crown extending from the angled portion, and wherein another inner void space is formed between the skirt wall and the crown.

18. The irrigator of claim 10, wherein the nozzle has a height dimension, and extends above the top end a distance of less than approximately two height dimensions of the nozzle.

19. The irrigator of claim 18, wherein the top end defines a crown extending out of the top end;

and

the nozzle is positioned at least partially over and extends from the crown.

20. The irrigator of claim 10, wherein the angled portion tapers down as the top end extends away from the switch.

21. A powered irrigator comprising,
