DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a respiration aiding device for stimulating a kinetic central nervous system (which conducts dilation and contraction of nasal meatuses) of a nose by pressuring a nasal septum, and thus expanding the nasal meatuses.
BACKGROUND ART
Iinner surface of nasal cavity is covered with a mucos membrane. Particularly, the turbinate bones located at the deep ends of the nares are abundant with venous plexuses. When the venous plexuses swell due to stipulation such as cold air, the nasal meatuses become narrow to decrease an air inflow through the nose, thus causing a respiration difficulty. When a human being lies face up with narrowed nasal meatuses, a root of a tongue plunges into a deep end of the throat and thus a passage of air is narrowed. As the air taken in through a mouth passes through the narrow passage, the relaxed soft palate vibrates to cause a snore. At this time, if the air inflow through the nose is sufficient, the snore is prevented because an intraoral soft tissue hardly vibrates.
A respiration aiding device for increasing an air inflow through the nose by expanding the nasal meatuses is helpful in increasing a quantity of oxygen uptake during exercise so as to improve an athlete's capability.
There has been proposed a respiration aiding device, as shown in FIG. 6, which comprises a U-shaped spring rod a formed in such a shape that a space between the ends thereof is a little wider than a space between the nares in a natural state, and expander portions b having a larger diameter than a spring rod a. For wearing this respiration aiding device, the expander portions b are inserted into the right and left nares while inwardly pressing the both ends of the spring rod a, and the spring rod a is released. Then, the respiration aid is retained in place by a force exerted by the spring rod a which attempts to restore its original width, and the nares are expanded outward.
However, this respiration aiding device gives a strong sense of incompatibility because the nares are forcibly expanded by the physical forces. Since the spring rod a has to possess a spring force of a certain level or higher, the diameter and rigidity thereof can not be set so small. This may result in interfering with or hindering respiration. Moreover, when the spring force of the spring rod a weakens because of repeated use, the respiration aiding device easily comes off in wearing it.
Further, as shown in FIG. 7, there is known a respiration aiding device in which presser portions d are provided at both ends of a resilient clip-like link portion c, and the right and left presser portions d abut on each other in a natural state.
With this structure, the nasal septum is caught by the right and left presser portions d by the spring force of the link portion c, working on the kinetic central nervous system for the nose by stimulating the nerves in the nasal septum so that the nasal meatuses are expanded to ease respiration. However, also in this structure, the spring force of the link portion c is utilized for retaining the respiration aiding device in the nose, and therefore the link portion c is formed relatively large in diameter and rigid. This causes an interference with respiration and can not prevent the respiration aiding device from coming off due to the weakened spring force.
DISCLOSURE OF THE INVENTION
An object of the present invention is to provide a respiration aiding device capable of making a link portion thin and soft, causing no interference with respiration, giving less sense of incompatibility when worn, with no concern about coming off after a long-term use.
A respiration aiding device of the present invention is a small appliance for assisting respiration by expanding the nasal meatuses when worn in the nares, comprising: a link portion formed into a substantial U-shape and having elasticity and both ends to be inserted into right and left nares; a pair of nasal septum presser portions formed at the both ends of the link portion; and a pair of magnets mounted
