The present invention in general relates to treating sleep disorders. More particularly, the invention relates to an improved apparatus for treating patients suffering from Obstructive Sleep Apnea (OSA).
Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Obstructive Sleep Apnea (OSA) is an increasingly common disorder that, if left untreated, is associated with an array of adverse health consequences, including cardiovascular disease, metabolic disorders, cognitive impairment, and depression. Obstructive Sleep Apnea (OSA) occurs when the muscles in the back of a patient's throat relaxes more than usual to allow normal breathing. These muscles support structures including the back of the roof of the mouth (soft palate), the triangular piece of tissue hanging from the soft palate (uvula), the tonsils, and the tongue. When the muscles relax, the airway narrows or closes as breathe is taken in and breathing may be inadequate for 10 seconds or longer. This may lower the level of oxygen in the blood and can cause a build-up of carbon dioxide. The brain may sense this impaired breathing and briefly rouses the subject from sleep so that the subject can reopen the airway. This awakening is usually so brief that it may occur that the subject may not remember it. The patient can become awake due to the shortness of breath that corrects itself quickly, within one or two deep breaths. The patient may make a snorting, choking or gasping sound. This pattern can repeat itself five to thirty times or more each hour, all night long. These disruptions can impair the ability to reach the desired deep, restful phases of sleep, and the subject probably may feel sleepy during waking hours. People with obstructive sleep apnea therefore may not be aware that their sleep was interrupted. In fact, many people with this type of sleep apnea think they slept well all night.
Second, OSA is associated with major comorbidities including (i) daytime somnolence; (ii) impaired cognition; (iii) poor quality of life; (iv) increased risk of motor vehicle accidents; (v) there is emerging evidence to suggest that OSA is an independent risk factor for a variety of adverse cardiovascular outcomes; (vi) the clinical disorder, defined as more than five abnormal breathing disturbances (hypopneas or apneas) per hour of sleep combined with symptoms of daytime sleepiness, affects at least 2-4% of the adult population; (vii) although non-obese individuals may suffer from OSA, obesity is the main epidemiologic risk factor; (viii) increases in body mass index; (ix) central accumulation of adipose tissue and neck circumference are strong predictors of disease.
Thus, efforts have been made in the current art to overcome the abovementioned limitations with such efforts although making an attempt at solving leaves open substantial room for improvement. One such solution is the common usage of intraoral device to address OSA. The most commonly used intraoral devices for OSA include (i) mandibular advancement plate or appliance; (ii) mandibular advancement plate with the tongue holder; (iii) palatal lift prosthesis; (iv) electronic vibrating devices. All the aforementioned devices while making an attempt at solving have a tendency to create inconvenience and nuisance in the present anatomy intraoral. Therefore, there exists a need in the art to provide an improved, reliable, and efficient solution for treating patients suffering from obstructive sleep apnea (OSA).

The present disclosure relates to an improved apparatus for treating sleeping disorders. The improved intraoral maxillary device is designed to overcome the problems created by existing intraoral devices. The improved maxillary device/appliance is enables partial detaching/disassembling, easy cleaning, quick replacement, and is comparatively more effective in terms of engagement with the maxillary teeth as compared to existing intraoral devices used for the obstructive sleep apnea.
In an embodiment, the hollow plate of the apparatus 100 may be formed with two separate parts. The hollow plate may comprise the upper portion 112 and the lower portion 114. The lower portion 114 of the hollow plate can be detached/separated from the upper portion 112 whenever desired by the subject. The upper portion 112 and the lower portion 114 may maintain a constant gap/distance to each other throughout entire length of the apparatus 100. The sleep disorder associated with the subject may be obstructive sleep apnea or any other sleep disorders based on breathing. The bulge member 104 may be attached about an anterior portion 122 of the hollow plate 102 and disposed near anterior portion of the hard palate. The bulge member 104 may enable the anterior portion of tongue of the subject in resting position within the bulge member 104, thus preventing the tongue of the subject to retract towards the mouth region. The bulge member 104 plays a vital role for enabling sufficient delivery of air towards the mouth region, by resting the tongue (in forward position than normal) near the anterior portion 122 of the hollow plate 102. The tongue of the subject may be held/rest in its anatomical and physiologic position via the bulge member 104. In other words, the bulge member 104 may be referred as tongue holding attachment.
In an embodiment, the hollow plate 102 of the apparatus 100 may be formed with two separate parts. The hollow plate may comprise the upper portion 112 and the lower portion 114. The lower portion 114 of the hollow plate can be detached/separated from the upper portion 112 whenever desired by the subject. The lower portion 114 of the hollow plate may be connected to the upper portion 112 via an interlocking means, which are present at the surface of the upper portion 112 and surface of the lower portion 114. The interlocking means may be a mechanical arrangement, but not limited to, screws, dowels, protrusions, and the like.
In another embodiment, the lower portion 114 of the hollow plate may be connected to the upper portion 112 either via an undercut arrangement implemented in the lower portion 114 and the upper portion 112, or via a press fit arrangement. The detachment/separation of the lower portion 114 portion from the upper portion 112 enables easy cleaning of the apparatus whenever the subject desires. Furthermore, the two part hollow plate 102 may provide comfort to the subject along with best adaptability over the subject's maxillary teeth.
In an embodiment, the bulge member 104 may bend downwards and form a shape similar to a scoop. The surface of the bulge member 104 may further comprise a V-shaped notch 150 that facilitates easy entry of the tongue associated with the subject and further enables the provision for the tongue frenulum. Further, the bulge member 104 may prevent the tongue of the subject from slipping out of the bulge member 104, and retract back towards the mouth region.
As further shown in
In an embodiment, the apparatus 100 can further include an upper curved plate portion 142 having maxillary teeth receptacle 144 disposed about the anterior portion 122 of the hollow plate 102. The upper curved plate portion 142 of the hollow plate 102 is configured to grasp through its maxillary teeth receptacle 144, at least a portion of maxillary teeth 146 associated with the subject. The maxillary teeth receptacle 144 is designed to provide a support for the apparatus 100 such that the apparatus 100 does not release itself from its implemented position which is as shown in
In an embodiment, the apparatus 100 comprising the upper portion 112 and the lower portion 114 may be of Ethyl Vinyl Acetate (EVA) material. At first, the Ethyl Vinyl Acetate material may be placed in a tooth tray. Further, the tooth tray (along with the Ethyl Vinyl Acetate material) may be dipped into warm water in order to soften the Ethyl Vinyl Acetate. In the next step, the tooth tray can be placed in the mouth on upper arch teeth so that the Ethyl Vinyl Acetate can adapt the shape of maxillary teeth of the subject and fit in a perfect manner. Furthermore, the material of the bulge member 104 may be Ethyl Vinyl Acetate (EVA) or any other material having similar properties of flexibility and anti-slipping. In another embodiment, the material of the apparatus 100 may be epoxy resin, wherein the apparatus 100 is fabricated using 3D printing technique It is to be appreciated that the apparatus 100 can be manufactured using any method known in the art including, without limitation, additive manufacturing, injection moulding, etc.
In an embodiment, the apparatus 100 can be custom-made based on the subject. Each and every aspect of the apparatus 100 can be designed based on specific characteristics associated with the subject. For example, for one subject, it may occur that a higher or lower thickness than the aforementioned 2 mm with respect to the hollow plate 102, be relevant and useful. Other factors may include the nature and strength of the maxillary teeth receptacle 144 with respect to its function of grasping the maxillary teeth 146, the nature and strength of the bulge member 104 with respect to resting of the tongue, without limitations. In an embodiment, an apparatus (like 100) can be made based on relevant inputs such as the above by means of computer aided design or CAD.
Thus, the improved maxillary appliance (i.e. the apparatus 100) is an effective intra oral device used for the obstructive sleep apnea. It can also be modified, manipulated (as to its components and its aspects), and utilized for other conditions and disorders. The apparatus 100 is easy to adapt since it fits directly on the patient's teeth. The apparatus 100 can be designed patient to patients. The apparatus 100 helps to maintain contentious air flow through the hole present in anterior region. Due to hollow design of the apparatus 100 the air is directly guided posterior to the tongue thus reducing the obstruction. Since the apparatus 100 remains in proper occlusion with the opposing arch patient feels comfortable to (i) Swallow; (ii) Move the tongue freely in the mouth; (iii) Even drink water with the plate and chew food if required; (iv) Since the vertical height is increased in specific limit that reduce TMJ problems; (v) Assist in respiratory distress such as asthma, SARS/Covid-19, etc.
In accordance with embodiments of the present disclosure, an improved apparatus for treating sleep disorders, described above may have following advantages including but not limited to:
The embodiments, examples and alternatives of the preceding paragraphs or the description and drawings, including any of their various aspects or respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, unless such features are incompatible.
