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.

Disclosed is an exoskeleton wearable device configured to push a condyle out from a glenoid structure of a skull made of two bellows shaped actuators each having an elliptical cross-section; an upper part configured to be fixed on a forehead of a patient and provide a base for the two bellows shaped actuators; and a lower part configured to be fixed on a mandible of the patient and substantially static to the mandible but moveable in a horizontal plane and a vertical plane with respect to the upper part.

Embodiments of the innovation relate to a jaw range of motion device that includes a conical base having a first end and a second end and a helical ridge carried by the conical base and disposed between the first end and the second end. The helical ridge and the conical base define a channel between adjacent helical ridge portions. The jaw range of motion device also includes a handle disposed at the second end of the conical base. When a user inserts the jaw range of motion device between his teeth, the user can apply a self-directed manual force to the device by generating a twisting motion on the handle to provide an incremental jaw range of motion.

An improved hand tool with molar as resistance point comprises a holding unit, a pivoting unit, an expansion unit and a clean jacket. The holding unit has a first end and a second end. The first end is provided for holding by a user, and the pivoting unit is pivotally connected to the second end correspondingly. A butt end and a connection end are respectively formed at two ends of the expansion unit, the butt end correspondingly butts a plurality of molars of the user, the connection end is pivotally connected to the pivoting unit correspondingly, and the clean jacket is correspondingly sleeved on the expansion unit.

The present invention provides devices and methods for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device includes structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

This application discloses systems and methods of applying vibration to a targeted area on an individual that is experiencing pain, discomfort, or other musculoskeletal symptoms. Steps of the method include lengthening followed by oscillation and vibration. The lengthening step requires positioning the individual (e.g., with the help of a stretching cage) such that the individual experiences a stretching sensation in a targeted area (e.g., a group of muscles, ligaments, tendons, etc.). Next, the individual oscillates in and out of that lengthened position while vibration is applied to the targeted area. It has been discovered that these techniques can bring about dramatic and quick improvements in flexibility and range of motion, while also diminishing symptoms like pain and discomfort.

A gum soother with a vibrating and detachable head. The gum soother can have a wand or spherical body with a vibrating device inside. The vibrating device can be in mechanical communication with one or more detachable heads. The detachable heads can have a variety of chew tips to soothe gums.

Systems and methods for airway management are provided. The airway management devices may be configured to align the oropharyngeal, laryngeal and tracheal axes of a person's head and/or support a neck region and chin and posterior mandibular region of a person. The airway management devices may provide forces similar to forces provided by a conventional head tilt chin lift maneuver and a conventional jaw thrust maneuver.

Disclosed herein is a method of treating neurodegenerative diseases involving accumulation of abnormal proteins in the central nervous system (CNS) of a user. The method includes utilizing an intraoral device to apply photobiomodulation and vibration to specific points on hard and soft palates of the user to stimulate the user's glymphatic system and decongest hyperphosphorylated tau and amyloid proteins and toxins, and simultaneously with the utilization of the intraoral device, applying a transcranial device to exert vasopneumatic compression and photobiomodulation on the user's head and neck to stimulate the user's lymphatic system and enhance the flow of lymphatic fluid towards the subclavian lymphatic pathway.
