Nasal filter structure
View Patent ↗A nasal filter structure includes an artificial filter that inconspicuously covers the nasal passage with a screened nasal dilator. The structure includes a nasal dilation strip preferably positioned to affect the area of nasal flex points to aid in dilating a nasal passage in an area near a nasal flex point.
1. A nasal filter comprising:
an outer ring having an outer periphery and an inner periphery sized to the periphery of a user's nasal orifice;
a filter layer having an outer periphery larger than the inner periphery of the outer ring,
but smaller than the outer periphery of the outer ring, and being bonded to a side of the outer ring;
an adhesive on an opposite side of the outer ring for bonding the outer ring to the columella, a nasal sill, an alar sidewall and the facet of the user's nose;
an additional adhesive at opposing locations of the adhesive and positioned to bond to natural flex points of the user's nose; and
a dilator positioned between the additional adhesive to open a nasal passage, wherein the dilator includes a plurality of curved portions to fit a structure of the nasal filter and to fit the natural flex points of the user's nose.
2. A nasal filter according to claim 1 , further comprising:
an outer filter layer positioned over the filter layer.
3. A nasal filter according to claim 2 , wherein the outer filter layer comprises a nonwoven material.
4. A nasal filter according to claim 1 , wherein the filter layer comprises a nonwoven material.
5. A nasal filter according to claim 1 , wherein the dilator includes curved portions at distal ends thereof.
6. A nasal filter according to claim 1 , wherein the dilator includes a locking mechanism.
7. A nasal filter according to claim 6 , wherein the locking mechanism includes a hinged locking mechanism.
8. A nasal filter according to claim 7 , wherein the locking mechanism includes a cylinder locking mechanism.
9. A nasal filter according to claim 6 , wherein the locking mechanism includes a ratchet locking mechanism.
