Description

Technical Field of the Invention

The present invention relates to a nostril dilation mask, and more particularly, to a nostril dilation mask capable of maintaining a nostril opened when worn. Background of the Invention

It is described in, for example, Japanese Patent Application Laid-Open No. 9-241106, for use in maintaining the nostrils open to facilitate breathing or assist breathing. Such nasal dilatation tapes are known.

The tape consists of an elongated tape that spans the nose column of the user, and a band-shaped plastic elastic member provided on one side or inside of the tape over most of its length. The part of the tape that comes into contact with the user's nose is provided with an adhesive. Then, when this tape is applied to straddle the nostril, the plastic elastic member is bent, and the elastic member expands the nostril due to the elasticity of the elastic member trying to return to a flat state. It has the mechanism of improving and increasing the amount of oxygen inhaled.

Such a nostril dilation tape is marketed under the trade name “PLEASE LIGHT” (3M Company), and is widely used in various sports fields where it is desired to increase the amount of oxygen inhaled.

By the way, depending on the occupation or work, it is sometimes necessary to always wear a dust mask or the like, and in recent years, the number of wearers of the mask not only to prevent colds but also as a measure against hay fever has increased. I have. However, these masks cause breathing difficulty when worn for a long period of time. In particular, masks for hay fever treatment have a problem that the breathing difficulty is further increased because the filter has fine eyes.

An object of the present invention is to provide a nasal dilatation mask that can eliminate such breathlessness when wearing the mask. Disclosure of the invention

In the nasal dilatation mask according to the present invention, an elastic member having a return behavior to a shape closer to flat than a bent shape straddling the nasal column is attached to the mask body so as to straddle at least the user's nasal column when the mask is worn. The face contact portion corresponding to the elastic member is provided with an adhesive.

According to the nostril-expanding mask of the present invention, when the mask is worn, the face contact portion corresponding to the elastic member, that is, the portion of the mask that contacts the nose or both outer sides of the nose is coated with the adhesive applied thereto. Since it is adhered to that part of the face, the elastic member is attached to the front of the user's face in a state of being bent so as to straddle the nose column, and this elastic member is closer to flat than the bent shape straddling the nose column Since the patient is going to return to the state, the nostrils are dilated by the return force, the air flow in the nostrils is improved, the amount of oxygen inhaled is increased, and breathlessness is eliminated.

The elastic member can be attached to an outer surface, an inner surface, or an inner surface of the mask body. If the elastic member is to be attached to the outside or inside of the mask body, it must be fixed together with the mask body, and the adhesive is applied to the inner surface of the mask body or to the part of the mask body that comes into contact with the outside of the nose. It should just be done.

When the elastic member is provided on the inner surface of the mask main body, the adhesive is applied to the elastic member at the portion in contact with the nose or both outer sides of the nose and z or the nose or both outer sides of the nose of the elastic member of the mask main body. What is necessary is just to give to the peripheral part of the part which contacts.

The elastic member may have a length that extends to the vicinity of the user's both bones. In this case, it is preferable that the adhesive is applied to a portion in contact with the vicinity of both sides of the user. Thus, the elastic member has a length extending to the vicinity of the user's both bones, and the adhesive is in contact with the user's both sides so that it can be engaged with both the user's both sides. In this case, the streaks can be pulled forward by the elastic member, so that the nostrils can be further expanded and the degree of relieving breathlessness can be improved. The pressure-sensitive adhesive may be applied only to a portion in contact with the vicinity of the both bones.

According to another aspect of the nostril-expanding mask according to the present invention, when the mask is worn, the mask has a length at least straddling the nose column of the user, and is more nearly flat than the bent shape straddling the nose column. An elongated tape provided with a strip-shaped elastic member having a habit of returning to its original shape over the majority of its length on one surface or inside is attached to the inner surface of the mask body, and the tape and z or the elastic member It is characterized in that an adhesive is applied to the nose or to the part in contact with both outer sides of the nose.

According to such a configuration, the attachment of the elastic member to the mask body is facilitated, and as described above, when the mask is worn, the face contact portion corresponding to the elastic member, that is, the nose or nose of the mask The part that contacts both sides of the face is adhered to that part of the face by the adhesive applied to it, so that the elastic member is attached to the front of the user's face in a state where it is bent over the nose column. However, since this elastic member tries to return to a state that is almost flatter than the bent shape that straddles the nose column, the return force expands the nostrils, improves the air flow through the nostrils, and increases the amount of oxygen inhaled. Then, the breathlessness is resolved.

Also in this case, the elastic member and the tape may have a length extending to the vicinity of the user's both bones, and the adhesive may include the elastic member and the tape.

It is preferable that the tape or the tape is applied to a portion in contact with the vicinity of the both bones of the user.

In any of the configurations described above, the mask main body may be provided with a lower portion that is locked to the user's chin. In this case, since the lower side of the mask body is locked to the chin, there is an advantage that the mask is prevented from slipping even when the mouth is moved.
