Definitions
- the present invention relates to a tongue position control device during sleep used for the purpose of suppressing snoring and treating patients with obstructive sleep apnea syndrome and the like.
- OSAS Obstructive sleep apnea syndrome
- the first factor is a decrease in the tension of the upper airway dilators (including the tongue muscles), which is seen in the stage from awakening to sleep. Airflow (black arrow in FIG. 13) is secured at awakening, but if the upper airway dilator muscle activity decreases due to falling asleep, the tongue sinks (moves toward the pharynx) and pushes the soft palate toward the pharynx ( (White arrow in FIG. 14).
- the upper airway (called Velopharynx) at the back of the soft palate becomes particularly narrow, and the patency of the airflow decreases (black arrow in FIG. 14).
- this Velopharynx has been shown to be the main site of upper airway obstruction in OSAS.
- this decrease in the activity of the upper airway dilator muscle is a physiological phenomenon that is also seen in healthy subjects (people who are not OSAS patients), and this phenomenon alone does not cause OSAS. Therefore, as a second factor, there is an anatomical abnormality of the upper airway form.
- the upper airway is constricted even at awakening due to excessive soft tissue in the oral cavity due to obesity, etc., it is considered that even a slight narrowing of the upper airway due to falling asleep significantly reduces the upper airway patency and causes OSAS. It is done.
- the conventional OSAS treatment methods are roughly classified into surgical treatment and conservative treatment. If the surgical treatment, soft palate plastic surgery (Uvulopalatopharyngoplasty; UPPP) or maxillomandibularadvancement (MMA), is successful, OSAS will be radically cured. On the other hand, because of the possibility of sound / swallowing dysfunction after surgery, the possibility of recurrence of OSAS, the irreversible operation, and the validity of the adaptation criteria, there are many objections. Only a limited number of patients choose treatment.
- nCPAP nasal Continuous Positive Airway Pressure
- nCPAP nasal Continuous Positive Airway Pressure
- nCPAP is a treatment method using a device that prevents upper airway obstruction by applying positive pressure from a mask attached to the nose and maintaining the air pressure in the upper airway at positive pressure.
- the intraoral device is a device that keeps the lower jaw or tongue in front and maintains the upper airway in an enlarged manner, and is roughly divided into a mandibular advancement device (MAD), an anterior tongue maintenance device (Tongue)
- MAD mandibular advancement device
- Tongue anterior tongue maintenance device
- TRD anterior tongue maintenance device
- Both nCPAP and intraoral devices can improve and maintain OSAS and have established safety.
- nCPAP and intraoral devices do not provide a fundamental cure for OSAS, and patients must use these devices for extended periods of time. For this reason, provision of an apparatus which is effective for OSAS and has little patient burden is eagerly desired.
- NCPAP has a high OSAS improvement rate, but has low compliance (probability of being used as instructed) due to nasal symptoms due to positive pressure and discomfort due to wearing a mask, and there are many patients who have dropped out of treatment.
- the activity of the upper airway dilator has a role of maintaining the patency of the upper airway, but when positive pressure is applied to the upper airway, the muscle activity is suppressed (see, for example, Non-Patent Document 3). . That is, nCPAP certainly improves OSAS, but partially reduces the protective function of OSAS inherent in humans.
- the intraoral device is simple, inexpensive and easy to use, and can be applied to nCPAP dropouts.
- an effect as high as nCPAP cannot be obtained (for example, see Non-Patent Document 6).
- MAD is more effective in improving OSAS than TRD, but because the position of the lower jaw is fixed in the forward direction, the load on the teeth and the temporomandibular joint is heavy, and tooth movement, discomfort and pain in the temporomandibular joint, etc. due to long-term use There is a high probability that side effects will be caused (see Non-Patent Document 7, for example). For this reason, it can be said that the mental and physical burden of the patient by use is also large.
- MAD acts as an orthodontic device, and mandibular anterior movement by using the device promotes mandibular growth (see, for example, Non-Patent Document 8). Therefore, on the other hand, improvement of OSAS symptom is expected, but there is a concern that it causes reverse occlusion. Thus, when using MAD for pediatric OSAS patients, indications are limited to patients with a small mandible.
- TRD is also an intraoral device, but the design and treatment principle is different from MAD.
- the integrated mouthpiece on the upper and lower jaw dentition is the same as MAD, but the airway in the posterior part of the tongue is enlarged by sucking and holding the tongue in the front direction in the socket provided in the front part. is there.
- the mouthpiece is integrated with the upper and lower jaws, the position of the lower jaw cannot be changed like MAD.
- the lower jaw usually opens downward and downward due to gravity and lowering of the activity of the closing muscles (see Non-Patent Document 9, for example), but this physiological position change is hindered when TRD is worn. Will be.
- Non-Patent Documents 11 and 12 Humans originally have nasal breathing, which has been considered to be a physiological breathing mode. Considering this point, it is reasonable that nCPAP and TRD are basically designed to perform nasal breathing when worn. However, when the nasal cavity is completely blocked for some reason, the breathing is maintained by switching from nasal breathing to mouth breathing. Furthermore, even when nasal congestion occurs in a range that does not lead to complete occlusion, or even under certain physiological conditions (for example, when the ventilation rate is improved), the human starts partial mouth breathing (for example, Non-Patent Document 11). And 13). In addition, even in healthy normal adults, it is reported that there are people who perform nasal breathing and mouth breathing in addition to nasal breathing (see Non-Patent Document 14, for example).
- OSAS patients with partial mouth breathing the mouth is an important respiratory route.
- OSAS patients often have nasal congestion associated with allergic rhinitis or the like (see, for example, Non-Patent Document 13), and nCPAP compliance is significantly reduced in these patients. If a patient wearing nCPAP attempts mouth breathing, the positive pressure in the upper airway is released and air leaks from the mouth, so that the treatment with nCPAP becomes ineffective.
- the MAD may provide air holes between the upper and lower jaw splints, but if the size of the air holes cannot be sufficiently secured due to the structure, the compliance is lowered.
- TRD originally aims to prevent mouth breathing and promote nasal breathing in addition to improving OSAS (see Patent Document 1).
- the TRD cannot perform mouth breathing because of the structure in which the upper and lower jaw sprints and a socket for positioning the tongue forward are provided in between.
- Patent Document 2 a method and a device for treating obstructive sleep apnea with negative pressure in the oral cavity of a patient have been proposed (see, for example, Patent Document 2).
- the patient's soft palate and surrounding soft tissue are pulled toward the oral cavity, the tongue is pulled toward the hard palate, and the patient's upper airway is maintained open.
- the patient's burden on the non-physiological condition of creating a negative pressure in the entire oral cavity is expected to be large, and a problem remains in compliance.
- the mouthpiece with integrated upper and lower jaws is worn, the physiological position change of the lower jaw is hindered, mouth breathing cannot be performed, and side effects on the teeth due to long-term wearing of the mouthpiece are concerned. This is the same as MAD and TRD.
- An object of the present invention is to provide an apparatus that effectively improves OSAS, has a low mental and physical burden on a patient, and is less likely to cause a decrease in compliance or side effects.
- the inventor of the present invention is more effective in preventing occlusion of the soft palate rear part in order to improve OSAS; without using an upper and lower jaw integrated mouthpiece, By sucking the tongue using a suppository with a lower jaw-mounted sprint and a capsule, the tongue can be prevented from sinking and the obstruction of the soft palate can be prevented directly; using the lower chin-only sprint Thus, the present inventors have found that the physiological movement / position change of the lower jaw is not hindered and mouth breathing can be performed, and the present invention has been completed.
