ABSTRACT:
The invention relates to a device for unidirectionally dispensing a hygienic cleaning and/or flushing liquid into the nasal and sinus cavities when an occluder is inserted into one of the nostrils. The liquid is contained in a pliable container which, upon insertion of the occluder into one of the nostrils and deformation of the container per se by squeezing, will cause the liquid to move via a passageway to the occluder and into the nostril. The device is provided with an anti-retractive valve which permits a unidirectional flow of the liquid only in a dispensing direction so any contaminated liquid that had been previously dispensed cannot reenter the container through the liquid dispensing passageway.
