Abstract: An adapter cap is configured to convert a plastic water or drinking bottle into a nasal washing device. The cap has a connector portion or mechanism configured for engagement with the neck of a plastic water bottle in place of a conventional bottle cap, and a tapered applicator or spout portion having a tip with an opening which is configured for placing into a nostril of a user during a nasal washing procedure.

Abstract: A nasal passage washing device includes a pliable body including an open top; and an applicator cap removably attached to the pliable body to cover and uncover the open top. The applicator cap includes an applicator tip having a substantially frustoconical configuration sized and shaped for receipt at least partially within a nostril of a user for sealing engagement therewith, the applicator tip including a hole to transfer washing solution there through, a washing solution transfer tube in communication with the hole of the applicator tip and a bottom of an inside of the pliable body to transfer washing solution from the bottom of the inside of the pliable body to the hole of the applicator tip, and a one-way air valve that only allows air flow into the pliable body through the one-way air valve and does not allow air flow and washing solution flow out of the pliable body through the one-way air valve.

Abstract: A method of using a nasal wash system includes providing a nasal washing device including a container including a saline solution, a cap for the container, a delivery tube carried by the cap for withdrawing saline solution from the container, an atomizing nozzle for spraying the saline solution, a conduit carrying the atomizing nozzle, the conduit including a malleable portion, and a pump mechanism coupled to the malleable conduit and including a movable pump member; adjusting the malleable portion of the conduit to a desired configuration to control a point of impact of a discharge mist from the atomizing nozzle; and moving the movable pump member of the pump mechanism so that saline solution is withdrawn from the container through the delivery tube, through the pump mechanism, through the conduit, and sprayed out of the atomizing nozzle as a discharge mist, while the atomizing nozzle remains stationary.
