The invention relates to a suction nozzle of the nasal aspirator with a one-way air flow selection valve system for a nasal aspirator which comprises three parts perfectly assembled to one another: an outer case, an inner case and a flow selection valve membrane, the result of which is a single fixed body which houses a valve system therein and from which a suction cannula projects at its proximal end and a hollow body suitable for being coupled to a tube of a nasal aspirator projects at its distal end. A nasal aspirator comprising said suction nozzle is also contemplated. |
