  Hereinafter, embodiments of the present invention will be described in detail.

  As shown in FIG. 7, the nasal mask 1 according to an embodiment of the present invention is inserted into the nostril 51 from the front end side when attached to the nose 50, and pollen, dust, etc. in the air enter the nasal cavity 53. Used to prevent As shown in FIGS. 1 to 6, the nasal mask 1 includes an insertion piece 10, a support member 20, and a filter 30. The insertion piece 10 and the support member 20 are transparent, translucent, or a resin-made member having the same color as the skin so that the appearance when the nose mask 1 is attached to the nose 50 becomes natural.

  The insertion piece 10 is an elastic rod-like member that has a U-shape as a whole, and is symmetrical with respect to the imaginary line L1 in FIG. The insertion piece 10 includes a base portion 11, a pair of sandwiching portions 12, and a pair of distal end portions 13. The base portion 11, the pair of sandwiching portions 12, and the pair of distal end portions 13 are sequentially arranged from the proximal end side to the distal end side of the insertion piece 10, and are integrally formed continuously.

  The base portion 11 is curved in a circular arc shape whose center is located on the imaginary line L1 in FIG. 1, in this embodiment, a dominant arc shape, and has a predetermined width W1 so as to have sufficient strength as shown in FIG. It has a flat plate shape. The base portion 11 is arranged so that the distal end side of the insertion piece 10 is opened, and is large enough to fit the distal end portion of the nasal septum 52 through the open portion and inside the base portion 11 when the nasal mask 1 is attached to the nose 50. It is assumed.

  As shown in FIGS. 1, 2, and 5, each sandwiching portion 12 is bent at an obtuse angle at the boundary between the base end side portion 12 a and the tip end side portion 12 b so as to have sufficient strength as the base portion 11. Are formed in a flat plate shape having a predetermined width W1. The base end side portion 12a extends substantially parallel to the imaginary line L1 in FIG. 1 from each open end of the base portion 11 toward the tip end side of the insertion piece 10. The distal end side portion 12b extends from the boundary toward the distal end side of the insertion piece 10 while being inclined in a direction away from the imaginary line L1.

  As shown in FIG. 5, each distal end portion 13 has an enlarged diameter portion 13 a on the proximal end side, and is formed in a substantially linear shape except for the enlarged diameter portion 13 a. Each distal end portion 13 extends from the extending end of the distal end side portion 12b of each sandwiching portion 12 toward the distal end side of the insertion piece 10 in an inclined state in a direction approaching the imaginary line L1 in FIG. That is, the pair of tip portions 13 are arranged so as to incline in directions close to each other. Further, a retaining portion 13c having a diameter slightly larger than that of the main linear portion 13b is formed at the extending end of the tip portion 13.

  Thus, in the insertion piece 10, the base end side portion 12a of each sandwiching portion 12 has the outermost diameter portion of the base portion 11 positioned in the direction orthogonal to the imaginary line L1 in FIG. It protrudes in the direction approaching the imaginary line L1 rather than the front-end | tip part 13 which continues through. That is, a pair of clamping part 12 will protrude in the direction which mutually adjoins in each base end side part 12a. Here, the width in the direction orthogonal to the imaginary line L <b> 1 between the pair of sandwiching portions 12 is set to be shorter than the width between the pair of nostrils 51.

  Moreover, each clamping part 12 and each front-end | tip part 13 become elastically movable to the direction separated while being urged | biased in the direction close | similar to the imaginary line L1 in FIG. Thus, as shown in FIG. 7, when the nasal mask 1 is inserted into the nostril 51 from the distal end side and the distal end portion of the nasal septum 52 fits inside the base portion 11, the pair of distal end portions 13 are positioned in the nasal cavity 53. In this state, the pair of sandwiching portions 12 are sandwiched between the nasal septum 52 while elastically expanding in a direction away from each other at the nasal septum 52.

  Each support member 20 is a flexible umbrella-shaped member. As shown in FIGS. 3 and 5, each support member 20 includes a base portion 21, a plurality of first wing portions 22, a reinforcing portion 23, and a plurality of second wing portions 24. The base 21, the plurality of first wings 22, the reinforcements 23, and the plurality of second wings 24 are arranged around the base 21 with the first wings 22, the reinforcements 23, and the second wings. The portions 24 are arranged so as to be positioned, and are integrally formed continuously.

  The base 21 is formed in a disk shape having a predetermined thickness. The outer diameter of the base portion 21 is set shorter than the outer diameter of the enlarged diameter portion 13 a of the distal end portion 13 in the insertion piece 10. The thickness of the base 21, that is, the width in the direction perpendicular to the board surface is set to be shorter than the width between the enlarged diameter portion 13 a and the retaining portion 13 c of the distal end portion 13. A through hole 21 a is formed at the center of the base 21. The diameter of the through hole 21a is set to be substantially the same as the outer diameter of the straight portion 13b of the tip portion 13.

  Each first wing portion 22 is formed in the shape of a flexible thin plate bar. The first wings 22 are arranged at predetermined intervals in the circumferential direction of the base 21. The first wing portion 22 has a base end connected to the outer peripheral portion of the base portion 21, projects radially from the outer peripheral portion of the base portion 21 toward the radially outer side of the base portion 21, and is orthogonal to the board surface of the base portion 21. It is curved toward one side of the direction to go.

  The reinforcement part 23 is formed in the annular | circular shape which has flexibility. The width in the radial direction of the reinforcing portion 23 is set to be substantially the same as the width in the short direction of the first wing portion 22. The thickness of the reinforcing part 23 is slightly smaller than the thickness of the base part 21 and is set to be approximately the same as the thickness of the first wing part 22. Further, the inner diameter of the reinforcing portion 23 is set larger than the outer diameter of the base portion 21. And the reinforcement part 23 is arrange | positioned concentrically with the base 21, and is connected with the midway part of the longitudinal direction of each 1st wing | blade part 22 which cross | intersects.

  Each second wing portion 24 is formed in a thin plate bar shape having flexibility. The width in the longitudinal direction of the second wing portion 24 is set shorter than the width in the longitudinal direction of the first wing portion 22. The second wing portion 24 is disposed between the adjacent first wing portions 22 and equidistant from both the first wing portions 22. The second wing portion 24 is connected to the reinforcing portion 23 at each base end and protrudes radially outward from the reinforcing portion 23 in the radial direction of the reinforcing portion 23, that is, radially outward of the base portion 21. The base 21 is curved toward one side in a direction orthogonal to the board surface.

  Thus, in each support member 20, the vent 20 a penetrates between the tip of the base portion 21, the first wing portion 22 adjacent to each other, and the reinforcing portion 23 in a direction perpendicular to the board surface of the base portion 21. It is formed. Similarly, between the first wing portion 22, the reinforcing portion 23, and the second wing portion 24 adjacent to the first wing portion 22, the vent hole 20 b penetrates in a direction orthogonal to the board surface of the base portion 21. Formed. That is, a large number of vents 20 a and 20 b are formed in each support member 20.

  Further, the first wing portion 22 and the second wing portion 24 are alternately arranged at equal intervals in the circumferential direction of the base portion 21 and the reinforcing portion 23, and the protruding ends of the first wing portion 22 and the second wing portion 24, respectively. Are aligned on a virtual circle centered on the center of the base 21. The area of the virtual circle is set to be appropriately larger than the opening area of the nose mouth 51. When the nasal mask 1 is inserted into the nostril 51 from the distal end side, the first wing portion 22 and the second wing portion 24 come into contact with the inner surface of the nasal cavity 53 on the respective protruding sides and approach the base portion 21. Will be bent.

  The filter 30 is composed of a fiber filter that filters air containing pollen, dust, and the like, and is formed in a disk shape as shown in FIGS. 3 and 4. The radius of the filter 30 is set to be smaller than the sum of the radius of the base portion 21 of the support member 20 and the width in the longitudinal direction of the first wing portion 22 and larger than the radius of the reinforcing portion 23. Further, as shown in FIG. 5, a through hole 30 a is formed at the center of the filter 30. The diameter of the through hole 30a is set to be substantially the same as the outer diameter of the straight portion 13b of the tip portion 13.

  Here, the filter 30 can also be configured by a two-layer or three-layer filter including a filter 31 having water absorption. For example, as shown in FIG. 6A, the filter 30 can be constituted by a two-layer filter by superposing a filter 31 having water absorption on a filter 32 for dust prevention. Alternatively, as shown in FIG. 6B, the filter 30 can be constituted by a three-layer filter by sandwiching a filter 31 having water absorption from both sides with a dustproof filter 32.

  In such a configuration, the retaining portion 13c of the distal end portion 13 of the insertion piece 10 is strongly inserted into the through hole 30a of the filter 30, and the straight portion 13b is continuously inserted into the through hole until the enlarged diameter portion 13a and the filter 30 come into contact with each other. 30a is inserted. Next, the retaining portion 13c of the distal end portion 13 of the insertion piece 10 is strongly inserted into the through hole 21a of the base portion 21 of the support member 20, and then the linear portion 13b is in contact with the expanded diameter portion 13a and the base portion 21. Is inserted into the through-hole 21a until they come into contact with each other. Accordingly, the filter 30 is fitted and attached to the distal end portion 13 of the insertion piece 10. At the same time, the support member 20 is fitted and attached to the distal end portion 13 such that the first wing portion 22 curves toward the distal end portion 13 side, that is, the proximal end side of the insertion piece 10.

  The attachment of the support member 20 and the filter 30 to the insertion piece 10 is performed at both distal end portions 13 of the insertion piece 10 to assemble the nasal mask 1. As a result, the two support members 20 are arranged at a predetermined interval across the imaginary line L1 in FIG. 1, and are disposed so as to be inclined in a direction close to the imaginary line L1, that is, in a direction close to each other. . Further, the filter 30 is disposed along each part of the support member 20 inside the outer peripheral part of the support member 20 while being sandwiched between the distal end portion 13 of the insertion piece 10 and the support member 20. That is, the support member 20 is laminated with the filter 30 and is disposed closer to the distal end side of the insertion piece 10 than the filter 30. In addition, the first wing portion 22 and the second wing portion 24 of the support member 20 protrude outward in the radial direction of the support member 20 and the filter 30 from the outer peripheral portion of the filter 30.

  When the nasal mask 1 is used, as shown in FIG. 7, the nasal mask 1 is attached to the support member 20 and the filters 30 attached to the distal end portion 13 of the insertion piece 10 from the distal end side thereof. To the nostril 51. When the nasal mask 1 is inserted by a predetermined amount, the nasal septum 52 is accommodated inside the insertion piece 10 base 11, and the pair of sandwiching portions 12 are sandwiched by the nasal septum 52 (nasal vestibule) from the both sides of the nasal septum 52, The insertion piece 10 and thus each support member 20 and each filter 30 are fixed to the nose.

  At the time of fixing, the first wing portion 22 and the second wing portion 24 of each support member 20 are bent following the inner surface of the nasal cavity 53, and a part of the first wing portion 22 and the second wing portion 24, that is, Only the protruding side is in contact with the inner surface of the nasal cavity 53, and the proximal end sides of the first wing part 22 and the second wing part 24, the base part 21 and the reinforcing part 23 are arranged so as to face the nasal cavity 53. In this way, the nasal mask 1 is attached to the nose 50, and pollen and dust in the air are prevented from entering the nasal cavity 53 through the nostril 51.

  In addition, the position of the inner surface of the nasal cavity 53 where the projecting sides of the first wing portion 22 and the second wing portion 24 of the support member 20 are in contact with each other is obtained by changing the width in the line direction of the imaginary line L1 in FIG. The nasal cavity 53 is set as appropriate so as not to irritate as much as possible. Further, the nasal mask 1 can be reused after being used once after being used.

  As described above, the nasal mask 1 according to an embodiment of the present invention is inserted into the nostril 51 from the distal end side when attached to the nose 50 to prevent entry of pollen or dust in the air into the nasal cavity 53. An arc-shaped base portion 11 and a pair of sandwiching portions 12 extending from the two open ends of the base portion 11 toward the distal end side and projecting toward each other. The pair of distal end portions 13 that extend from the respective sandwiching portion 12 side toward the distal end side and incline toward each other, and are sandwiched between the nasal septum 52 by the pair of sandwiching portions 12. It has an elastic rod-shaped insertion piece 10, a disk-shaped base portion 21, and a plurality of flexible wing portions 22, 24 protruding radially from the base portion 21, and this base portion 21 is the insertion piece 10. The pair of tip portions 13 are attached to each other and are inclined in directions close to each other. Attached to the distal end portion 13 of the insertion piece 10 and sandwiched between a part of the distal end portion 13 and the support member 20, the inner side of the outer peripheral portion of the support member 20 A filter 30 disposed along the support member 20 is provided.

  Thus, when the nasal mask 1 is mounted on the nose 50, the filter 30 or the entire outer peripheral portion of the support member 20 does not contact the inner surface of the nasal cavity 53, but a part of the support member 20, that is, both wings 22 and 24. Only the projecting side of this contacts the inner surface of the nasal cavity 53. That is, the contact area between the filter 30 of the nasal mask 1 or its peripheral portion and the inner surface of the nasal cavity 53 is smaller than that of the conventional nasal mask described above. Therefore, it is possible to obtain a natural wearing feeling without a sense of incongruity when the nasal mask 1 is worn, and to improve the wearability of the nasal mask 1 to the nose 50.

  In addition, the filter 30 and the support member 20 are disposed closer to the nasal septum 52. Therefore, the filter 30 and the support member 20 can be easily inserted into the nostril 51. At the same time, the insertion piece 10 inserted into the nostril 51 can be securely sandwiched between the nasal septum 52 and the nasal mask 1 can be prevented from falling off from the nostril 51.

  In the nasal mask 1 according to an embodiment of the present invention, the filter 30 is configured by a two-layer or three-layer filter including a water-absorbing filter 31.

  As a result, when the nasal mask 1 is attached to the nose 50, the runny nose can be absorbed by the filter 31 having water absorption. Therefore, it is possible to prevent the feeling of wearing the nasal mask 1 from deteriorating when a runny nose appears. Moreover, it is possible to prevent the runny nose from leaking from the nostril 51 to the outside.

  Further, as shown in FIGS. 8 to 10, the nasal mask 1 as described above is housed in a case 40 as a plurality of sets. The case 40 is a hollow rectangular parallelepiped member having a size that allows a plurality of nasal masks 1 to be juxtaposed, and includes a box-shaped case body 41 that opens on one side and a box-shaped lid 42 that opens on one side.
