Abstract: A system for safely irrigating nasal and sinus cavities using a portable and reusable device which can be conveniently coupled to a fluid container, wherein the system includes an adapter end for coupling to the fluid container, an insertion end which directs fluid from the fluid container into the nasal and sinus cavities while preventing damage thereto by preventing insertion of the insertion end into the nasal cavities beyond a predetermined length, and a curved section of tubing which is coupled to the adapter end and the insertion end, wherein the curved section of tubing makes the user hold the fluid container in a correct position for directing solution from the fluid container into the nasal and sinus cavities.
