Abstract: A fitting is disclosed that adapts the wand of an oral irrigation device for use in nasal irrigation. An oral irrigation wand is inserted into a fitting, which is then placed in the nostril. The fitting is compatible with the wands of many brands and models of oral irrigation devices. The fitting dampens the change in amplitude of the pulsations from pulsating-type irrigation devices, resulting in a safer, more pleasant nasal irrigation experience. The fitting is removable and protects the user's nostril from contact with the wand and allows the wand to be used for both nasal and oral irrigation. The fitting allows for comfortable insertion into a nostril, providing a complete seal with both the nose and the nasal irrigation device, to promote both a tidy and effective nasal irrigation experiences. The fitting is sturdy, simple and easy to manufacture, providing for long life and performing well even with long, repetitive use.
