Description

-1 NASAL DEVICE FIELD OF INVENTION {0001} The present invention relates to a device for assisting breathing through thenose particularly for use while a person sleeps. The present invention has particularly but not exclusive application for treating snoring and sleep apnea conditions. BACKGROUND OF THE INVENTION {0002} There are a number of nasal devices that have been developed to assist a person with their breathing while they are asleep. These nasal devices usually dilate or maintain the air passageway within each nasal cavity. In US patent US5895489 there is described a nasal dilator having two open framework tubes connected together with a bridge section. The frames are insertable into the nostrils but deep nasal insertion is prevented by a larger external end contacting the narrowing nasal passage and preventing further insertion. US patent US6562057 discloses another similar nasal device having tubular elements with elongate apertures and a curved bridge section that maintains the tubular elements in a spaced apart and substantially parallel relationship. German patent specification DE29616121 discloses a nasal device having two tubular members and an alternate bridge section. Another similar nasal device was disclosed in Swiss patent specification CH689199. The nasal device consisted of two tubes 10 mm to 13 mm long and molded in one piece with a connecting filament from silicon.

-2 {0003} The disclosed nasal devices however can become accidentally dislodged and fall out or repositioned with reduced effectiveness. Furthermore where the nose or nasal septum have a different size or shape or a person has a deviated septum, current nasal devices may not fit or comparatively be more easily dislodged. OBJECT OF THE INVENTION {0004} It is an object of the present invention to provide an alternate nasal device for maintaining an air passageway within the nose that overcomes at least in part one or more of the abovementioned problems. SUMMARY OF THE INVENTION {0005} In one aspect the present invention broadly resides in a nasal device for maintaining an air passageway within the nose including a dilator member having two nasal members integral with or connectable to a bridging member, said bridging member joins the two nasal members so that they are in similar orientation and substantially parallel with each other, each of said nasal members are shaped to form an air passageway when inserted within a nasal cavity; and a spring biased clip positioned on each of the nasal members wherein in use the two nasal members within respective nostril cavities form the air passageways and are maintained adjacent the nasal septum by the spring biased clip. {0006} The nasal member may be any suitable shape which in use is able to form an air passageway within the nasal cavity. Preferably each of the nasal members is hollow and substantially tubular in shape. Each of the nasal members preferably -3 has an internal bore extending the length of the member. Preferably each of the nasal members has a truncated conical shape where the diameter across one end is smaller than the diameter across the opposite end. Preferably each of the nasal members has a truncated conical shape wherein there is a bore extending the length of the member. The narrower end of the nasal member is preferably positioned further within the nasal cavity than the larger end when the dilator member is inserted within the nose. Preferably the narrower end of the nasal member has a rounded edge to reduce the risk of damage to nasal tissue. {0007} Each nasal member preferably has a locating recess on an internal wall for the positioning of the clip. {0008) Preferably the bridging member is connectable to or adjacent the larger end of each nasal member. {0009} The bridging member is preferably integral with the nasal members to form the dilator member. Alternately the bridging member includes a separable bridge portion that can attach onto complementary protrusions on each of the nasal members. {0010} The bridging member preferably includes a tab extending outwardly from the nasal member. The tab preferably enables a person to hold and withdraw the nasal device from the nose.

-4 {001 1} The dilator member preferably is made of soft material. The dilator member is preferably made of soft, resiliently deformable material. The dilator member preferably is made of plastics. The dilator member is preferably made of non-toxic, non-abrasive, soft medical plastics to minimize the risk of damage to nasal tissue. {0012} The spring biased clip is preferably substantially U-shaped. The spring biased clip preferably has locating protrusions on opposing clip ends. The locating protrusions preferably oppose each other. The locating protrusions assist in positioning the clip by locating within the respective locating recess in each nasal member. When the spring biased clip is located within each nasal member, the clip preferably abuts each nasal member substantially against the nasal septum wall. When in position the clip preferably prevents accidental dislodgement of the nasal members in the nasal cavities and movement of the nasal members by airflow with inhalation and expiration. {00131 The spring biased clip is preferably made of hard and stiff material. The spring biased clip is preferably made of surgical steel. {0014}ln another aspect the present invention broadly resides in a nasal device for maintaining an air passageway within the nose including a dilator member having two nasal members integral with a bridging member, said bridging member positions the two nasal members so that they are in similar orientation and substantially parallel with each other, each of said nasal members are hollow and substantially tubular in shape; and -5 a spring biased clip positioned on each of the nasal members, wherein in use the two nasal members within respective nostril cavities form air passageways and are maintained adjacent the nasal septum by the spring biased clip. {0015}Preferably each of the nasal members has a substantially truncated conical shape where the diameter across one end is smaller than the diameter across the opposite end. Preferably each of the nasal members has a substantially truncated conical shape wherein there is a bore extending the length of the member. Preferably the narrower end of the nasal member has a rounded edge to reduce the risk of damage to nasal tissue. {1 0016} Other features described with reference to the first aspect may also be applicable to the second aspect of the nasal device. BRIEF DESCRIPTION OF THE DRAWINGS (0017}ln order that the present invention can be more readily understood and put into practical effect, reference will now be made to the accompanying drawings wherein: Figure 1 is a perspective view of the dilator member of the preferred embodiment of the nasal device; Figure 2 is a diagrammatic view of the preferred embodiment of the nasal device; Figure 3 is a plan diagrammatic view of the preferred embodiment of the nasal device; -6 Figure 4 is a plan diagrammatic view of the dilator member of the preferred embodiment of the nasal device; and Figure 5 is a sectional view of the preferred embodiment of the nasal device with the clip in the operational position. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT {001 8} With reference to the figures there is shown a nasal device 10 including a dilator member 11 and spring biased clip 12. The dilator member 11 has two hollow tubular nasal members 13. Each nasal member 13 decreases in diameter to form an elongate truncated cone. The larger end 14 of each nasal member 13 is joined by a bridging portion 15 which maintains the nasal members 13 in a similar orientation and in spaced relationship with each other. The bridging portion 15 has a tab 17 allowing a person to hold and withdraw the nasal device 10. The tab 17 extends outwardly from the nasal members 13.
