A device for delivering fluid to a nasal cavity comprises an elongated member comprising a hollow exterior cannula and a hollow interior cannula. The interior cannula is flexible, is at least partially housed within the exterior cannula, and comprises an inlet for intake of the fluid and at least one outlet for ejecting the fluid. The exterior cannula has outlets for ejecting the fluid which are positioned within the nasal cavity by inserting the distal end of the device through a given nostril. A portion of the device has a continuously curving centerline that divides the device into a first and second lateral section. At least one outlet is positioned in each of the first and second lateral sections. Rotation of the distal section of the interior cannula within the exterior cannula permits the ejection of fluid predominantly out of outlets on respective lateral sides of the outer cannula.

The present invention provides an apparatus for delivering a fluid to a subject. The apparatus includes: (a) a vessel fillable with an amount of water through an opening; (b) a cap for covering the opening and configured to store an additive to be released into the water; and (c) a fluid delivery attachment including a body having: (i) a cap engaging portion configured to rupture a portion of the cap in order to release the additive into the water; (ii) a fluid outlet; and, (iii) a passageway extending between the cap engaging portion and the fluid outlet, wherein, the cap engaging portion is engageable with the cap so as to allow fluid to flow between the vessel and the fluid outlet.

An improved nozzle includes a nozzle body having a conical portion and a lower portion. The nozzle is used for irrigating nasal cavities and sinuses. Passageways for fluid are disposed in the conical portion, and fluting is provided on the lower portion to facilitate manual grasping. In one embodiment, each of the passageways is formed as a bore having a central axis aligned at a specific angle to a centerline of the nozzle body. In one embodiment, the passageways are evenly spaced about the central axis, and the specific angle is at 45 degrees.

A nasal irrigation device and system is described that provides gentle and effective irrigation of the nasal cavity. Small volumes of irrigation fluid are directed towards the wall of the sinus cavity and collected centrally, using a pliable irrigation device. A focusing feature is provided that serves to hold the attention of children undergoing nasal irrigation in order to distract them from the procedure. Such a focusing feature can be in the form of a stuffed or toy animal that envelops or forms part of the nasal irrigation system.

A nasal flushing catheter, made of silicone latex, thermoplastic elastomer or other soft and elastic material, can be operated by the patients. The catheter has a closed end and an open end on the opposite side. There are multiple side-holes near the closed end. This catheter, when adapted to a connector and further connected to a syringe, can eject multiple strong thin spouts within the nasal cavity and nasopharynx for cleansing mucus and crust. The catheter may contain at least one stylet to improve its controllability. By a given injection rate of 10 cc/sec using a syringe, the average vertical height of spouts can be predicted by the total area of side-holes, the catheter is therefore classified as following: 1. a low pressure catheter, having 3.367 mm.sup.2?4.123 mm.sup.2 of total areas of side-holes to eject 30 to 45 cm spouts; 2. a medium pressure catheter, having 2.381 mm.sup.2?3.367 mm.sup.2 of total area of side-holes to eject 45 to 90 cm spouts and 3. a high pressure catheter, having less than 2.381 mm.sup.2 of total area of side-holes to eject longer than 90 cm spouts.

Systems and methods for nasal irrigation are provided in which a nasal irrigation device includes a source of saline solution, an effluent receptacle, a nasal interface, a vacuum source, a fluid passageway to communicate the source of saline solution with the effluent receptacle through the nasal interface and a nasal cavity of the user, and a switch and valve assembly for selectively controlling the vacuum source and flow of the saline solution through the fluid passageway. The saline solution source bottle is disposed relative to the device to provide gravitational inducement of saline solution to the nasal interface in engagement to the device user's nostrils. A combination of the gravitational inducement and the relative vacuum from an effluent receptacle generates a fluid flow for irrigating, cleansing and massaging the nasal cavity and ostia of a user. The entire device is assembled as a hand-held device for convenient lifting and disposal against the user's nostrils.

An automatic nasal washer includes a water storage portion, a control portion, and a nasal docking portion. The water storage portion is arranged with a water storage chamber. The control portion is fixed to the water storage portion and is arranged with: a water inlet channel communicated with the water storage chamber; a switch valve configured to control the water inlet channel to be communicated with or dis-communicated from the water storage chamber; a water return channel communicated with the water inlet channel; and a suction member configured to provide a negative pressure to the water return channel. The nasal docking portion is connected to a point where the water inlet channel is connected to the water return channel; and configured to output washing water from the water inlet channel to a nasal cavity and to withdraw waste water flowing from the nasal cavity to the water return channel.
