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.

L'invention concerne un dispositif de lavage de passages nasaux comportant un corps souple comprenant une partie haute ouverte ; et un bouchon applicateur fixé de façon amovible au corps souple afin de couvrir et de découvrir la partie haute ouverte. Le bouchon applicateur comprend un embout applicateur présentant une configuration sensiblement tronconique dont les dimensions et la forme lui permettent d'être au moins partiellement reçu à l'intérieur d'une narine d'un utilisateur en un contact étanche avec celle-ci, l'embout applicateur comprenant un trou à travers lequel peut être transférée une solution de lavage, un tube de transfert de solution de lavage en communication avec le trou de l'embout applicateur et un fond intérieur du corps souple afin de transférer la solution de lavage du fond intérieur du corps souple au trou de l'embout applicateur, ainsi qu'un clapet anti-retour à air permettant uniquement l'entrée d'un flux d'air dans le corps souple à travers le clapet anti-retour à air et empêchant le flux d'air et la solution de lavage de s'échapper du corps souple à travers le clapet anti-retour à air.
