A NASAL FILTRATION APPARATUS

This International Application claims priority from a complete patent application filed in India having Patent Application No. 201811045380, filed on November 30, 2018 and titled“A NASAL FILTRATION APPARATUS”.

BACKGROUND

Embodiment of a present disclosure relates to nasal filtration and more particularly to a nasal filtration apparatus.

Millions of people suffer from stuffy nose or breathing problems, uncomfortable or impossible conditions with respect to nasal physiology of breathing problems. Filtering of inhaled air is one of the primary functions of the human anterior nasal cavity and upper respiratory tract. The natural filtration mechanism includes minute hairs or cilia, which functions as a safeguard against particles being deposited in the lower airways or ultimately in the bronchi. Common illness includes allergic reaction to particular pollen particles entering the body. The particle inhalation causes asthma and emphysema. However, the natural filtration of particles, where especially particles above 10 microns are deposited on the nasal mucosa membrane, for some individuals may be an extreme nuisance, as they develop allergic responses against such particles. Hence, various artificial nasal filtration device has been introduced to reduce the above-mentioned problems faced by the people.

Furthermore, existing mechanical nasal dilators and filtration devices are generally classified as external or insertable. The external type for example attaches a cap-like structure with a filtering material to the outside of the nose with adhesives. However, some of the disadvantages of this external prior art includes; skin irritation, skin discoloration, allergic reactions, not adjustable, uncomfortable, expensive, not reusable and does not accommodate the wide variety of nose sizes and configurations. Such devices can be put on one time and cannot be reused or readjusted. If they are put on wrong way, then the device must be removed and disposed. In addition, the force and contact of the cap-like structure across the nose causes discomfort. However, insertable type nasal dilators are uncomfortable, does not consider the wide variety of nose shapes and sizes, not adjustable, irritating and not effective. In addition, most of the such devices actually reduce nasal air filtration efficiency.

Hence, there is a need for an improved nasal filtration apparatus to address the aforementioned issues.
