Below are some excerpts from patent documents:

Nasal and nasopharyngeal cavities are common places for holding environmental allergens, such as pollen, fungal spores, animal body-originated dustings and volatile chemicals. These harmful agents cause allergic reactions and other ill consequences. Nasal and nasopharyngeal secretions combine with environmental particles to form big matters (solidified mucous) in the nasal cavity. These big matters narrow the airway and make the individual feel uncomfortable. Prior to the present invention, an aparatus and method to easily and effectively remove harmful agents from the nasal cavity and to prevent the formation of and remove the big matters in the nasal cavity has not been available to medical professionals and to the general public.

The human body is the only natural host for many kinds of pathogenic microorganisms. Nasopharyngeal mucous is one of the prominent places of viral shedding. These pathogens include, but are not limited to, influenza viruses, respiratory syncytial viruses and the like. The nasopharyngeal shedding of these pathogens is the major cause of person-to-person transmission. One skilled in the art will appreciate that those communicable pathogenic microorganisms present in the nasal and nasopharyngeal cavities will be decreased in quantity after the cavities have been cleaned. After nasal and nasopharyngeal cleaning, these infectious agents will be less likely to spread horizontally to non-carriers and/or vertically to the lower respiratory tract of the carrier.

Environmental pathogens may be encountered by inhalation. Legionella pneumophila, the causative agent of Legionnaire's disease presents in aerosols. It is generated from air conditioning cooling towers, cold water taps, showers and other water systems. Depending upon wind speed, Legionella pneumophila, in these aerosols, may be carried up to 500 meters and infect a large number of individuals. Promptly removing these aerosols from the nasal and nasopharyngeal cavities will greatly reduce the incidence of infection.

Several methods have been reported to be useful in cleaning nasal and nasopharyngeal cavities. Grossan invented a nasal irrigation system (NASAL IRRIGATION SYSTEM, U.S. Pat. No. 3,047,145, issued Nov. 12, 1974) which provided for an isotonic saline solution under pressure flowing into one nostril, passing through the nasolacrimal duct, where the solution passes, sequentially, into the ostia of the frontal sinus, the ethnoids, the maxillary and the sphenoid. The solution then moves past the outlet of the eustachian tube and then through the nasopharynx to the upper posterior portion of the other nostril and outwardly there through, passing the same ducts and ostia, in reverse sequence, before being discharged from the second nostril. This system has numerous and serious shortcomings. First, the cleaning solution cannot be completely drained from the deep regions of certain sinuses due to their cavity structure. Second, certain infectious agents might be moved from one place to another and stay there to cause a new infection. Third, some dried or hard matters in the nasal cavity might be carried inward to the sinuses. Fourth, hard matters might cause a blockage when they are forced to flow into narrow spaces, such as the eustachian tube. Therefore, the reported nasal irrigation system of Grossan cannot be widely used by the general public for cleaning nasal and nasopharyngeal cavities.

To improve the efficiency of nasal cleaning, a new type of nostril fitting is needed. The previous article has failed to suggest an NNC system that is simple in construction and easy to use and that allows for the cleaning of the nasal and nasopharyngeal cavities in the separated steps. Since the nasal cavity: (1) is naturally in the lowest position as compared to the nasopharyngeal cavity and the other sinus cavities; (2) collects secretions from other sinus cavities; and (3) is the first place to meet and store the foreign matters, it is obvious that the first step of the nasal and nasopharyngeal cleaning method should be to initially clean the nasal cavity. Therefore, a new step-by-step cleaning method is disclosed in this invention.

One important aspect of the NNC system according to this invention is the flat-head nostril fitting, or one-size-fits-all nostril fitting. The nasal fitting substantially prevents the NNC cleaning solution from leaking from the nostril during the irrigation step of the process. It has been observed that different people have different shaped nostrils and that not all people have round nostrils. Some people have an irregular opening, like a long narrow channel. Therefore, it is impossible to use the conical shaped nostril fitting of the prior art to prevent the liquid from leaking from the nostrils of these people. Additionally, the conical shaped nostril fittings of the prior art always create a certain amount of dead space between the inserted part of the nasal fitting and the wall of the nasal cavity.

Snoring is a major problem for many people. In fact, in the U.S. alone, about 90 million people suffer from snoring. This figure doesn't take into consideration the needless suffering of the loved ones living with them. Sleep deprived nights lead to irritation, tiredness, and a possible growing division or alienation between partners. Seeking a simple and effective solution honoring has been a major concern for a large number in our society. Snoring has become an everyday occurrence. It is much more common than many care to admit. Each nostril functions independently and synergistically in filtering, warming, moisturizing, dehumidifying, and smelling the air. The nostrils meet at the nasopharynx where mucous is accumulated. Although many factors cause snoring, the major reason may be that the nasal cavity is narrowed due to accumulated mixtures of mucous and environmental dusts. Habitual nasal cleaning will remove those accumulated dirty materials and help people to reduce snoring.
