Description

Mouth interface device

The present invention relates to a device and method for eliminating upper respiratory tract obstruction in patients with Obstructive Sleep Apnea (OSA) and snoring patients. More particularly, the present invention relates to a negative pressure port interface device for placing an inlet chamber.

Sleep Respiratory Suspension (OSA) is a symptom of repeated collapse of the respiratory tract during inhalation, which can cause apnea during sleep. The air pressure in the lungs and respiratory tract is reduced during inhalation. If at this moment, the muscle activity of the upper respiratory tract is reduced, the respiratory tract will tend to collapse. Before the apnea, the airway will begin to close and the patient will often start snoring. A phenomenon in which a snoring patient tries to fight a collapsed respiratory tract. These disorders occur in different locations along the respiratory tract in different patients, but there are two common locations in the throat and nasopharynx.

Patients with moderate to severe sleep apnea symptoms experience lethargy, fatigue, and mental discomfort during the day. In addition to these immediate problems, studies have shown that patients with sleep-discontinuation symptoms use more medical resources, and the risk of medical behavior failure increases, ultimately leading to higher mortality. If all the examples are considered, the mortality rate of patients with severe sleep apnea symptoms is estimated to increase three to six times. Sleep apnea symptoms are also hidden in many cardiovascular diseases, such as systemic hypertension and some degree of pulmonary hypertension. Symptoms of sleep apnea will increase myocardial infarction, cerebrovascular disease and heart rhythm The risk of uncertainty. Patients with sleep-disordered symptoms who are interrupted by sleep at night can also cause excessive sleep during the day and cause mental discomfort. Due to the compromise of the patient's neurological function, the patient's daily function is impaired during the day. They are more likely to cause mistakes and car accidents. Therefore, if the symptoms of sleep apnea are not treated, it can have serious negative consequences.

There are currently several treatments for patients with sleep-disordered breathing. Oral appliances are used to treat mild to moderate sleep-disordered breathing, but they often do not work well and can cause damage to the gums and teeth of patients. There are some procedures for treating sleep-disordered breathing, but these surgical procedures are invasive, expensive, and painful, with recovery periods of up to six months. The most common treatment for moderate to severe sleep apnea symptoms in adults is the use of a Constant Positive Airway Pressure (CPAP) Machine. Positive pressure breathing apparatus consists of a mask, a pump and a humidifier. The positive pressure respirator continuously blows high pressure air into the patient's nasal passages to keep the patient's airway clear during sleep. Positive pressure respirators are quite effective, but they can cause unpleasant side effects such as dry throat and blocked nasal passages. Patients who use positive pressure respirators often experience swelling and headaches in the morning. Positive pressure breathing apparatus also makes users and their families feel noisy and uncomfortable. Positive pressure breathing apparatus is the first line and gold standard treatment method today, but it has low adaptability due to its serious side effects.

A current improvement is to apply a negative pressure in the patient's mouth, and to pull the patient's tongue and soft palate forward by negative pressure to maintain the airway. For example, U.S. Patent No. 5,957,133, U.S. Patent Application Serial No. 2005/0,166,928, and No. 2006/0,096,600. Although theoretically feasible, these prior art techniques use large structures to clamp the teeth and/or hold and position the tongue. Furthermore, the negative pressure system is applied directly to the soft tissue of the tongue to keep the tongue positioned in the oral cavity. However, these practices can take up a lot of space in the mouth, causing discomfort and damage to teeth, gums and soft tissues. At the same time, the presence of larger devices can cause excessive salivation and nausea. Other major drawbacks of these practices still include that these oral devices involve surgical anatomy, which would require a special technician to provide a customized oral interface for each patient.

In view of the above, it is an object of the present invention to provide an alternative and improved oral interface device for treating sleep apnea symptoms and snoring and methods of use thereof. Another object of the present invention is to provide a small oral interface device that is comfortable and convenient to use and a method of using the same. It is still another object of the present invention to provide a small oral interface device and method of use thereof that is easy to implement and that effectively maintains a patient's airway during sleep.

The present invention provides an oral interface capable of eliminating or treating snoring and sleep apnea symptoms, and a method for using the same, which applies a negative pressure to the oral cavity via a small oral interface, and the negative pressure system uses the tongue Pull up and pull the soft palate forward. By moving the tongue and soft palate forward, the upper airway near the throat can be kept open to prevent breathing disorders during sleep. This negative pressure pulls the lip inwardly to close the mouth, thereby preventing air from entering the mouth from the outside. This negative pressure also pulls the soft palate into contact with the back surface of the tongue to create a closed area that prevents air from passing through. Enter the mouth from the nasal passages.

The invention provides a mouth interface device, which mainly comprises a connecting pipe, one end of which is connected to a negative pressure source; and a collapsible cavity, one end of which has an opening communicating with the connecting tube opposite to the negative pressure source. At one end, the other end of the collapsible cavity is in an open shape; and a non-collapsible structure is disposed on at least one inner wall surface of the collapsible cavity. When the collapsible cavity generates a negative pressure environment in the cavity through the negative pressure source, the tissue in the oral cavity will lean against the collapsible cavity, and the compression will cause the collapsible cavity to collapse, and the non-collapsed structure supports The collapsible cavity is configured to form a fluid passage inside the collapsible cavity to maintain communication with the negative pressure source; when the tissue in the oral cavity is to move, the collapsible collapsible cavity is restored to the original volume. The collapsible cavity increases the negative pressure by increasing the volume during the recovery process due to the increase in volume, and enhances the force of pulling back the oral tissue or avoiding the movement of the oral tissue.

In another aspect, the present invention provides a method for creating a negative pressure environment in a user's mouth to fix soft tissue in the oral cavity. The method can use the aforementioned oral interface device or other oral interface device that can achieve the same effect of fixing soft tissue in the oral cavity. The method comprises the steps of: placing a collapsible cavity of one of the mouth interface devices in a position of one-half or one-third of the front end of the tongue in the mouth of the user and the middle portion of the dental arch, and using the collapsible cavity One of the connecting tubes extends outside the mouth of the user; the connecting tube is moved to adjust the mouth interface device to an appropriate position, preferably, the connecting tube is moved to the user's tiger bite; The lip is closed; and the negative pressure source is activated to allow air in the oral cavity of the user to be drawn through the fluid passage inside the collapsible cavity and the connecting tube Leaving out, so that the user's mouth creates a negative pressure environment, and the tissue in the oral cavity will lean against the collapsible cavity, and the compression will cause the collapsible cavity to collapse; the method of the present invention may further comprise: using a non- The collapsible structure supports the collapsible cavity such that the collapsible cavity has a fluid passage formed therein to maintain communication with the negative pressure source; the method of the present invention may further comprise one of the collapsible cavities The outer wall surface uses a gripping structure. When the collapsible cavity collapses in a negative pressure environment, the grasping structure will abut and grasp the soft tissue in the oral cavity of the user to fix the soft tissue in the oral cavity. The method of the present invention may further comprise: using a patch to closely adhere to the lips of the user to prevent the user from involuntarily opening the mouth to maintain an oral negative pressure environment.

The foregoing oral interface device and method of use of the present invention only require a part of the pumping time, is very energy-saving and quiet, and can be more conformable to the shape of the oral tissue, and occupies less space in the mouth, and can provide better Comfort.

The objects, spirit and advantages of the invention will be apparent from the description of the appended claims.
