The NeilMed Naspira Nasal-Oral Aspirator is the world's most uniquely designed system, where several important safety, quality and efficacy features are combined. With our unique 2-in-1 design, you can either use it as a NeilMed NasaBulb aspirator or as an effective Nasal-Oral suction device where parents can use suction force generated by the mouth similar to sucking through a straw. By using the NeilMed Naspira, you can quickly remove nasal mucus safely and effectively by creating a negative airflow of 5 to 10 liters or more per minute plus longer duration of suction, as opposed to simply using a bulb aspirator where the suction duration is less than half a second. In addition, the NeilMed Naspira Nasal-Oral Aspirator features in-line disposable filters to protect the parent from contact with mucus. The one-way valve prevents a large volume of accidental air from the parent's mouth from blowing into the baby's nose and prevents pushing down of the mucus.
