The purpose of the present disclosure is to provide a tongue exercise apparatus for snoring prevention, wherein the apparatus can be useful for exercising the tongue in order to prevent snoring. A tongue exercise apparatus according to the present disclosure is a tongue exercise apparatus that a user can hold by hand and use to perform tongue exercises, the apparatus comprising: a handle which the user can hold by hand; a tooth engagement part which extends from the end of the handle and has an engagement groove that can engage with the ends of the teeth of the user; and an exercise assistant part which is connected to the tooth engagement part so as to be able to enter the mouth of the user, and has a protrusion portion that protrudes, in a direction intersecting with the direction in which the tooth engagement part extends from the handle, so that the tongue of the user can contact the protrusion.

According to the present disclosure, an oral rehabilitation device includes an air bladder and a pumping member. The air bladder includes a cheek-side membrane and a teeth-side membrane, and the cheek-side membrane and the teeth-side membrane are arranged opposite to each other. The pumping member is communicated with the air bladder, and the pumping member is configured for inflating the air bladder. The cheek-side membrane and the teeth-side membrane extend toward the outside of the air bladder when the pumping member is inflating the air bladder, and an extension of the cheek-side membrane is larger than an extension of the teeth-side membrane.

Maxillary and mandibular appliances can be mounted to a user's upper and lower jaws. The appliances can include a palatal pad, buccal tubes, hamular notch tubes, and an anterior deprogrammer. The various portions of the appliances can provoke beneficial reactions by muscles in the tongue and jaw area, massage the same muscles, or provide other beneficial effects.

An improved manual oral cavity expansion device comprising a fixing element with one end connected with a first holding element, and another end forming an accommodating portion protrudingly disposed with a pivoting portion; at least one linkage element disposed on the fixing element; a rotating element accommodated in an accommodating space of the accommodating portion and sleeved on the pivoting portion; a movable element with one end connected with a second holding element, and another end forming a movable portion correspondingly disposed in the accommodating space and sleeved on the pivoting portion; and an expansion unit. An outer circumference of the rotating element is arranged with a plurality of tooth elements in a row, and one end of the linkage element contacts the tooth elements. The expansion unit has a first expansion arm connected to the accommodating portion and a second expansion arm connected to the movable portion.

A device is described that can effectively increase the range of motion of a jaw of a patient to address physiological conditions that involve restricted range of motion of the jaw of the patient. The device can be used to apply opposing forces to the maxillary and mandibular teeth, which can stretch the temporomandibular joint and mandibular muscles, which in turn can aid in opening of the jaw. Furthermore, the device includes a spring, which is configured to be stretched when the patient performs mastication motions. Such stretching of the spring dynamically applies varying amounts of force on the jaw depending on the position of the jaw during the entire range of motion of the jaw, and severity of the physiological condition such as trismus. Such dynamic force requires the jaw to perform different amounts of work at various positions, which aids in the opening of the jaw.

The training device for chewing and swallowing can be used by patients who have difficulty chewing and/or swallowing to assist them to learn how to chew and swallow. The device includes a bolus delivery cylinder and a plunger. The bolus delivery cylinder can include a cylindrical housing having a peripheral wall and a hollow interior. The plunger can be slidably received in the cylindrical housing and secured thereto. In some embodiments the peripheral wall can be perforated. The interior of the housing is configured to accommodate small pieces of food. The bolus delivery cylinder can be made from a transparent, flexible material, such as silicon.

The present disclosure describes systems and methods for the treatment of obstructive sleep apnea. The system includes a mouthpiece. The mouthpiece includes a force plate that a user can press against with their tongue. Pressing the force plate enables the user to strengthen their tongue. The system also includes a control module that can measure the force applied to the force plate and provide feedback to the user about progress and the applied force.

A facial exercise apparatus for facial muscle and bone resistance training and method of use. The facial exercise apparatus includes one or more flexor arms and a mouthpiece stabilizer, each connected to a flexor head connector. The flexor arm(s) extend upward, downward, left or right from the flexor head connector, have contours to place the patient's lips, and provide a resistance force outward from the flexor head connector. In use, a patient places and bites down upon the mouthpiece stabilizer, places a portion of their lips along a contoured portion of one or more of the flexor arms, and pushes their lips toward the center of the flexor head connector against the resistance of the flexor arm(s). When done at regular intervals and increasing resistances, the apparatus can strengthen a patient's facial muscles and bone and reduce the cosmetic appearance of wrinkles on their face.

A positive expiratory pressure-generating device for reducing breathlessness in a subject with one or more pulmonary disorders is disclosed. The device is rigid and hollow and can be held in the mouth of the subject. The device has at least one air chamber, at least one opening in the portion of the device that is held in the mouth and at least one additional airflow orifice. The device is configured to increase expiratory resistance and can be supported by the mouth of the subject without the need for additional support by hands, another device or other means.
