Abstract

The utility model relates to a Ni-Ti marmen device for preventing snore, which is used to prevent snoring. The utility model comprises a plastic base 1, a snap ring 5, a support rod 2 arranged in the plastic base and a force application member 3 and a support plate 4 which are made from Ni-Ti marmen. One end of the force application member 3 is installed in the plastic base 1 and the other end is connected with the support plate 4. The utility model is fixed in the mouth of a patient by the snap ring 5 when used. The force which continuously effects on the support plate close to a big tongue or (and) a small tongue is very soft due to the low toughness and high elasticity of Ni-Ti alloy, which reduces the foreign body sensation of the patient. The utility model is widely welcomed by patients by clinic uses.

Description

Ni-Ti marmen device for preventing snore

A kind of niti-shaped memorial alloy snore stopper, this utility model belong to snoring treatment field, are used for preventing apnea syndrome between snoring and sleep period.

When sleeping, some people can snore, trace it to its cause mainly is because oral cavity internal (mainly being lisper and uvula) is wide, long or loose distortion hinders or part hinders that the regular path of nasopharynx part respiratory tract causes, at present the common method of treatment snoring has two kinds of excision and orthopaedic treatments, the two is compared, latter's risk is little, adapt to wide, fast and convenient, so quite be subjected to the favor of patient and medical matters circle, orthopedic treatment promptly utilizes certain special device to be seated in the oral cavity when sleep, to correct and to improve the deformation extent of big uvula, thereby the mediation respiratory tract prevents snoring, U.S. Pat 4304.227 has just disclosed a kind of device of snoring and grinding one's teeth in sleep of preventing, this is a kind of plastic device (see figure 1) of global formation, its groove position and patient go up the lower teeth engagement, the central cavity of after-opening utilizes negative-pressure sucking to cooperate with the big tongue of user is anterior, make with a thick tongue and protract, eliminate phenomenon with mouth breathing, reduce the space of being obstructed, nasal respiration road, thereby prevent snoring, but this device is not suitable for the snoring symptom that causes because of uvula, and because of sticking to move for a long time, tongue make the patient like a hen on a hot girdle when using, therefore also can cause the phenomenon of drooling, just more inapplicable with the people of mouth breathing when getting used to sleeping.

This utility model will design a kind of light flexibly exactly, and safety and comfort can rescue the snore stopper that causes snoring because of common cause during use.

Measure of the present utility model is to make force-applying piece with niti-shaped memorial alloy silk or sheet, push down in use cause snoring lisper or/and uvula, to play suitable push and block effect, thereby eupnea road from broadening nasopharynx position, prevent that snoring from taking place, for making the force-applying piece applied force can be distributed in patient's position, affected part (with a thick tongue or/and uvula) with dividing equally, end at force-applying piece also is connected with the plastics supporting plate, because the low rigidity that niti-shaped memorial alloy had, elastomeric property, make the continuous action stress that acts on the supporting plate very soft, make the patient reduce foreign body sensation, simultaneously do not influence tongue again and sometimes make rational swallowing act, reduce or avoid the phenomenon of drooling.

Now in conjunction with the accompanying drawings this utility model is illustrated.

Fig. 1 is a kind of device for preventing snoring sketch map among the US4324.227.

Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are this utility model sketch map, wherein Fig. 2 is big tongue snore stopper sketch map, Fig. 3 is a uvula snore stopper sketch map, and Fig. 4 and Fig. 5 are compound snore stopper sketch map, and Fig. 6 is double-arm big tongue snore stopper, Fig. 7 is the sketch map of force-applying piece and pole among Fig. 2,1 is plastic base among the figure, and 2 is pole, and 3 is force-applying piece, 4 is supporting plate, and 5 is snap ring.

This utility model is except including plastic base 1, outside the snap ring 5, also include and bury the pole 2 that is contained in the base 1, force-applying piece 3 and supporting plate 4, force-applying piece 3 employings have hyperelastic niti-shaped memorial alloy and make, preferably adopting nickel content is 50.3～52.3%(atomic percent) Nitinol of surplus titanium, one end of force-applying piece 3 buries and is contained in the plastic base 1, the other end is connecting supporting plate 4, also be that the other end of force-applying piece buries and is contained in the supporting plate 4, pass through snap ring 5 during use with in the snore stopper immobilized patients oral cavity, 1 pole 2 and force-applying piece 3 can fuse as shown in Figure 6, also can be discrete chorista, but the end of force-applying piece 3 and pole 2 are all buried and are contained in the plastic base 1, force-applying piece 3 and pole 2 can by, same material is made, also available different materials is made.Be positioned at the crooked radian of the force-applying piece 3 in affected part, should adapt with patient's the root of the tongue portion (for big tongue) or the former normal morphology of soft palate portion (for uvula).

When implementing, the uvula snore stopper also can be made as the single arm type of Fig. 2 and similar big tongue snore stopper shown in Figure 5 or double-arm, and concerning the patient who causes because of big uvula two aspects, can adopt compound snore stopper as shown in Figure 4 and Figure 5, it is to be made of two blocks of supporting plates that can suppress big tongue and uvula respectively, and two blocks of supporting plates are connected on the force-applying piece 3 separately.

This utility model can give the batch molding and also can bend temporarily, and existing good through the clinical result of use of the anti-institute of Luwan District tooth, the patient generally pleases oneself after using.
