Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snoring preventive device which is mounted in the oral cavity and prevents snoring by regulating the backward displacement of the lower jaw.

[0002]

2. Description of the Related Art As means for preventing snoring, various means have long been proposed. Broadly speaking, it is divided into a technology for awakening the snoring person by detecting the occurrence of snoring and a technology for suppressing the occurrence of snoring.

The former uses a method of detecting voice and giving an electrical stimulus. However, in terms of awakening the snoring person, not only sleep is disturbed but also the intensity of the stimulus required for awakening. Has been found to be impractical because it may vary from person to person or depending on the health condition of the day, which may cause health problems, or worse, a dangerous condition.

In view of the current situation, many techniques have been recently developed for suppressing the occurrence of snoring. The direction of such technological development is largely due to the clarification of the mechanism of snoring. That is, in the snoring, the internal organs of the oral cavity, especially the base of the tongue are extremely relaxed, and the rear airway a is narrowed or substantially occluded as shown in FIG. As a result, it is known that this is caused by the vibration of the soft tissue part of the relaxed tongue base b.

As a result of investigating the cause of this, as a means for suppressing the occurrence of snoring, measures such as suppressing the retraction of the base of the tongue and displacing the lower jaw forward have been taken.

For example, Japanese Examined Patent Publication No. 51-30718 proposes a technique for preventing the snoring from occurring by controlling the retraction of the tongue by maintaining the space between the palate of the upper jaw and the base of the tongue at a required distance. ing.

Further, in Japanese Patent Publication No. 5-78346, the distance between the upper teeth and the lower teeth and the relative position between them are such that the lower teeth are located in front of the upper teeth, that is, the lower jaw is displaced forward. A correction tool configured as described above has been proposed.

[0008]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The technique disclosed in Japanese Patent No. 0718 aims to regulate the retreat of the tongue by putting pressure on the palate and tongue and pressing the tongue while inserting the device into the oral cavity. Although it was very discomforting and even painful, unlike medical purposes, it was impossible to use it as a snoring preventive device that is always worn during sleep.

On the other hand, the correction device of Japanese Patent Publication No. 5-78346 uses a structure in which the upper teeth and the lower teeth are engaged with each other, so that no pressure is directly applied to the tongue or the palate in the oral cavity. I am trying. Therefore, it can be considered as a step forward in that there is no discomfort or pain in use such as pressing the tongue as described above.

However, this orthodontic appliance is provided with an inclined portion for pushing the front lower teeth forward so as to dilate the airway in the rear part of the oral cavity so that breathing can be performed easily. Since the lower teeth are guided at the time of biting so that the entire lower jaw is displaced forward from the normal position, the following problems occur.

Since the lower jaw is displaced forward by meshing the upper and lower front teeth, it is premised that this meshing is continued during sleep. However, when the mouth is opened due to muscle relaxation (relaxation of the tongue base and oral soft tissue, etc.) during deep sleep, the upper and lower anterior teeth are loosely engaged, and the lower teeth disengage from the inclined part and the lower jaw becomes normal. There is a problem that the mandible is returned to the position and the lower jaw is allowed to retract, and as a result, it is impossible to prevent the narrowing of the airway in the posterior part of the oral cavity.

[0012] Because the lower jaw is pushed forward from the normal position, the muscles supporting the lower jaw become tense, and the discomfort in the worn state is inevitable, and it is removed after a long sleep. There was a problem that the feeling of discomfort remained when I played.

[0013] During sleep, when a situation in which the mouth greatly opens due to muscle relaxation occurs, when the lower teeth come off the inclined portion and the lower jaw returns to the normal position or retracts to the posterior position, even if the mouth then closes, In order to move the lower jaw forward using this inclined part, it is impossible to do it unconsciously during sleep, and if this is done, it is necessary to wake up once and perform an appropriate operation. It was

Although the above-mentioned drawbacks of the prior art have been understood as to the mechanism of snoring, it is considered that the airway dilation by the forward displacement of the lower jaw is considered as a preferable solution as a countermeasure for it. .

[0015]

The basic point of view of the present invention is that the mechanism of snoring is that the organs in the oral cavity, especially the base of the tongue, are extremely relaxed, and the posterior airway is narrowed or substantially occluded. Although it is the same as the conventional one in understanding that snoring occurs, we have gained the following new recognition.

That is, the reason that the tongue base or the like relaxes to narrow the airway is not only the phenomenon of relaxation and retraction of the tongue base, but
At the time of opening due to snoring, the lower jaw does not make a simple rotational displacement about one pivot axis at the base of the skull, but it causes displacement to the throat side (occipital side) when supine That's what I focused on. At the same time, since some snoring is accompanied by some opening, the following attention was paid to this opening operation. That is, it was noticed that the snoring opening movement showed a large displacement (opening) in the vicinity of the front lip and a slight displacement in the vicinity of the posterior molar.

Based on this recognition, the inventors have come to the idea of preventing the position of the lower jaw from retreating from the position at the time of constant meshing of teeth so that the retreating tongue and the like are not vibrated. is there.

The present invention has been completed by further developing the above-mentioned viewpoint, and an object thereof is to provide a snoring preventive device which can solve the above problems.
