Definitions

  • the present invention relates to a nasal device and method for using the nasal device in the nostrils of a nose.
  • septoplasty is the surgery to correct the deviations or irregularities of the nasal septum.
  • the septum is the cartilage and bony partition that separate the two nostrils or nasal chambers of the nose.
  • great care is taken to avoid perforating the tissue covering the septum or weakening the structure of the nose.
  • An incision is often made internally on one side of the nasal septum.
  • the mucous membrane is elevated away from the cartilage and bone, obstructive parts are removed and the surgery may be performed, as required. Upon completion of the surgery, the mucous membrane is then returned to its original position.
  • the septum After a septoplasty, the septum must be stabilized and the walls of the nose must be kept in place .
  • the mucous membrane should be able to heal as quickly as possible.
  • two splints can be sutured to the septum so that one splint is placed in each nostril to stabilize the septum. This is inconvenient for the patient and the sutures of the splints must later be removed which may be painful and requires time of a specialist.
  • the nostrils may also be stuffed with nasal packs to keep the walls apart and to stop the bleeding.
  • One drawback is that it is difficult or impossible for the patient to breath through the nose while the nasal packs are inserted.
  • the method and nasal device of the present invention provides a solution to the above-outlined problems . More particularly, the method of the present invention is for using a nose device in a patient with a nose that has surgical scars or incisions after rhinoplasty or septoplasty.
  • a hollow resilient cylindrical body that has a mesh wall is provided.
  • the mesh wall has a plurality of elongate cross-linked members.
  • the wall has an axial opening defined therein with a first diameter and extending through the body. Prior to insertion, the body is compressed to reduce the first diameter of the opening. The compressed body is then inserted into a nostril. The body is permitted to expand inside the nasal cavity to conform to the inside shape of the nasal cavity.
  • the patient may breath trough the opening while the device is disposed inside the nose.
  • the surgical area is ventilated by the air flowing inside the opening to promote healing. Because the mesh wall is open, the conchas and the mucus membranes can function almost normally while the device is inserted in the nose.
  • the body may have loop ends that could be bent inwardly to make it easier to insert the body.
  • the body may also have opposite filament ends that may be bent outwardly to make sure the body stays inside the nose after expansion.

  • Fig. 11 is a detailed view of a cross-point showing an indentation.
  • the bendable nasal device 10 of the present invention has a cylindrical and hollow elongate body 12.
  • the body 12 has a cylindrical mesh wall 13 with a plurality of equilateral parallelogram- or diamond-shaped wall openings 14 defined therein by cross-hatching elongate filaments or members 16, 18. Openings with other shapes are also possible and any type of hollow cylinder with radial wall openings may be used.
  • the ' body could be any type of elongate body with radial openings defined in the walls and an axial opening extending along the length of the elongate body.
  • the device 10 of the present invention is therefore not limited to bodies with cylindrical walls that are based on a mesh or a net structure.
  • the body 12 may be compressed and inserted into a nostril, as outlined in detail below.
  • the body 12 may be mounted inside the nasal cavity by compressing the device prior to insertion and then permitting the body 12 to expand inside the nasal cavity and conform to the inside shape of the nasal cavity and provide support to the nose structure while allowing the person to inhale and exhale through the nostrils since the body 12 is hollow.
  • the body or bodies 12 may be used after surgery of the nose to support the nose during the healing process and to give the nose a symmetric appearance.
  • the body 12 may also be used for other applications such as supporting allergy filters inside the nose.
  • the body 12 may also be used for aiding the breathing during sleep or as a breathing aid in general .
  • a nose 50 may have nostrils 52, 54, a nasal septum 56 and outer nose walls 58, 59.
  • the nose 50 has a nasal cavity 60 defined therein.
  • Mucous membranes such as inferior nasal concha 62, middle nasal concha 64 and superior nasal concha 66, extend inwardly towards the septum 56. The conchas may clean, moisturize and cool/heat the air that is inhaled.
  • An inner airway passage 68 is defined at an inner end of the nose 50 so that air may be breathed in and out of the nose.
  • the cartilage of the septum 56 is covered with mucosa on both sides. After surgery of the septum it is important that the septum is straight and does not interfere with the airflow through the patient's nose. If the septum is off- center or deviated, it can cause an airway obstruction. Also, swelling often occurs after surgery that may hinder the airflow through the nose.
  • the septum 56 is typically approached surgically by making an incision or incisions 72 adjacent to the bottom of the septum 56 just behind the columella 70.
  • the columella 70 is the central column of skin, cartilage and tissue disposed between the nostrils but below the septum 56.
  • Fig. 4 shows the nasal device 10 inserted into one of the nostrils 52, 54 so that one of the openings 14 is disposed over the incision 72 and air that is inhaled into and exhaled out of the nose 50 come into contact with the incision 72 that needs healing so as to provide ventilation.
  • the fact that the incision and other areas that require healing are exposed to and ventilated by the air may enhance the healing process compared to being covered by a solid plastic segment. There is also less risk for irritations of the mucous lining.
  • the conchas 62, 64, 66 may function almost normally although the nasal device 10 is inserted into the nostrils.
  • the openings 14 not only enhance the healing of incisions but also permit the conchas to carry out their normal functions while the nasal device 10 is disposed inside the nasal cavity.
  • the end pieces of the device 10 may be bent outwardly, as shown by member 25 in Fig.
  • the device 10 could be molded into the bent shape in a molding tool that has the bent outer shape.
  • the body 12 may be made with injection molded polymer material that is flexible and resilient. The material and the thickness of the members determine the resiliency of the body 12.
  • any other suitable manufacturing technique may be used.
  • a medically accepted plastic material is used. It is also possible to use a bio-chemically and dissolvable material that has the desired elastic qualities.
  • the device 10 has elongate members 16 that are substantially parallel to one another and intermittently joined with elongate members 18 that extend across the members 16 at an angle to form a mesh pattern so that each intersection or cross-points 19 have the same thickness as the thickness of the members themselves.
  • the elongate members 18 are substantially parallel to one another so that the members 16, 18 define the diamond-shaped openings 14.
  • the body 12 may have cross-points 19a, 19b and 19c.
  • the cross-points 19a, 19b are separated by a distance (dl) and the cross-points 19b and 19c are separated by a distance (d2) that preferably is the same as the distance (dl) .
  • the members 16 and the members 18 form first obtuse angles alphal, alpha2 and alpha3 at the cross-points 19a-c when the body 12 is in a relaxed expanded position, as best shown in Fig. la.
  • the members 16 have end portions 20 and the members 18 have end portions 22 that converge at intersection end points 24 so that an acute angle beta is formed between the members 16, 18 at the intersection points 24.
  • the body 12 has end portions 26, 28 that are opposite the end portions 20, 22 and converge at intersection end points 30. Every other intersection end point 30 is joined by a loop 32 to make it easier to insert the body 12 so that no loose ends of the members 16, 18 that may get caught inside the nose during the insertion.
  • both ends of the body 12 have these arcs or loops so that it does not matter which end of the body 12 is inserted first.
  • the device 10 has one size that fit most noses and does not have to be cut.
  • the uncut end with the loops should be inserted first since the cut end may have protruding filaments and members that can get caught inside the nostril and nasal cavity.
  • the device 10 may have loops at both ends. It may be more comfortable for the patient if the round loops are disposed at the outer part of the nose also. This makes it also easier to remove the device from the nose.
  • the loops 32 at the end to be inserted may be inwardly bendable to form a slightly conical shape.
  • Fig. lb shows loops 33 that are inwardly bent during a molding process.
  • the loops 32 may also be made of a thinner material to make the loops easier to bend and conform to the shape of the inside wall of the nose when the body 12 is inserted therein without causing any damage.

  • This also applies to the bent free end 25 that may be pre-bent outwardly or inwardly in a mold, as desired. It is also possible to insert the free end first into the nostril.
  • An important feature of the present invention is that the body 12 is hollow and the members 16, 18 are bendable so that the diameter (Dl) of the hollow body 12 may be reduced, as desired, when the body is inserted into a nose nostril. If the body 12 has the diameter (Dl) in the expanded relaxed position, the diameter of the body 12 may be reduced to a smaller diameter (D2), as best shown in Fig.

  • the mesh of the body 12 should be resilient enough not to fold while the body is inserted into the nostrils. If the body 12 is undesirably folded, the opening 34 may close so that the patient cannot breathe through the opening.
  • the body 12 does not fold when it is compressed and the reduction of the diameter should be uniform so as to avoid any blockage of the opening 34.
  • the free flow of air also may improve the healing of the mucus lining and other parts of the nose that may have been operated on.
  • the body 12 consists of the mesh wall 13 with the openings 14, the air that flows inside the body 12 may come into contact with the area that has been operated on.
  • the body 12 is a mesh structure, a relatively stiff material may be used while providing sufficient bendability of the body 12 compared to a solid hollow cylinders. If solid hollow cylinders are to be sufficient bendable, a very flexible material must be used. This also means that the wall thickness must be relatively thick which makes the size of the axial opening small.
