Definitions
- the present invention refers to a nose filter, positioned on the outer side of nose, sticking to it, modelling according to its shape and showing two small filters corresponding to nost ⁇ ls
- the main purpose of an air filter is to hold inside its fibres, both natural and synthetic, dust, bacte ⁇ a, smog, pollen, etc, i e all those substances particularly irritant for buccal cavity and first respiratory tract
- filter masks positioned on the face, such as to cover both mouth and nose
- Fig. 1 is an aerial view of a nose filter according to the invention.
- Fig. 2 is a section of a front view of a nose filter fig. 1 according to the invention
- Fig. 3 is an aerial view of a different productive version as per fig. 1
- Fig. 4 is a section of a front view of a nose filter as per fig. 3
- Fig. 5 is an aerial view of a further productive version of the nose filter as per fig. "1
- Fig. 6 is a section of a front view of a nose filter as per fig. 5
- Fig. 7 shows an aerial view of a further productive version of the nose filter as per fig. 1
- Fig. 8 is a section of a front view of a nose filter as per fig. 7
- Fig. 9 is the profile of a face on which a nose filter as per fig. 1 has been applied, according to the invention.
- a first version of a nose filter according to the invention (indiicated with the arrow 1) is shown.
- This filter basically consists of a base or support material 2, similar to the material used for transdermic plasters, but any other material (fabric or synthetic) can be used to make this base, provided it has good performances in flexibility, compactness and resistance.
- Base material (2) has an adhesive surface (3) on which a thin layer of biocompatible gluing agent is applied, in order to adhere perfectly to the nose skin according to the nose shape.
- two filters (4) are inserted inside the fabric.
- These filters are made with porous material, such as activated carbon, polypropylene, alveolate resins, filtering fabric, etc.
- Filters (4) are ellipse-shaped with longitudinal sides slightly pressed and therefore straight (see fig.1 ref. 8) and parallel to the A-A' median axis of said filters (4).
- fig. 3 and 4 another version of nose filter (1) according to the invention is shown, which differs from Fig 1 and 2, due to the fact that
- the filters (4) are slightly curved to facilitate their wearability or introduction inside nost ⁇ ls
- a small round st ⁇ ng (5) in hydrophilic material is provided, in order to receive and stop mucus in case it should flow from nose
- FIG. 5 and 6 another version of nose filter (1) according to the invention is shown, which differs from the previous fig 1 and 2, because filters (4) are slightly curved to facilitate their wearability or their introduction inside nostrils, and because of the presence, at the centre of each filters (4), of a filte ⁇ ng membrane valve in elastic filtering material like polypropylene in order to facilitate the flow of expired air by increasing its speed and by eliminating moisture excess in nose vestibules
- FIG. 7 and 8 another version of nose filter (1) according to the invention is shown, which differs from the previous Fig, 1 and 2 for the presence of a pe ⁇ pheral edge (7) in elastic material all around base material (2), in order to increase adhesion of nose filter
- Fig 9 shows a practical application of nose filter (1), subject of our invention, modelled on user's nose, in this figure advantages are outlined, such as Use easiness - Small dimensions
