Apparatuses for plumping and toning facial muscles, and methods for using such apparatuses, are disclosed herein. A preferred embodiment of the apparatus is configured to work as an exercise weight for facial muscles, including as a lip plumper, and comprises an outer surface, an interior hollow, and a rim between the interior hollow and the outer surface. The preferred rim comprises an interior edge transitioning to the interior hollow, an exterior edge transitioning to the outer surface, and a recessed indentation, or dip, located between the interior and exterior edges. The preferred interior hollow is configured for the user to pucker at least a portion of the user's lip(s) into the interior hollow and support the weight of the embodiment, in whole or in part, by the lip(s). The embodiment may further include a sidewall, a lanyard hole, and an air hole.

An athletic mouthguard with lung exercising variable, two-way airflow-restricting valve is disclosed. The mouthguard has a mouthpiece with a lower tooth bed and an upper tooth bed overlying the lower. Outer and an inner sidewall connects the beds. A channel passes between the lower and upper beds with a first end open within the inner sidewall and a second end open within the outer sidewall. Certain embodiments include a channel wall which separates the channel into multiple channels. A manifold in fluid communication with the channel terminates to a centralized aperture with a valve seat. A rotatable valve member in the valve seat has an aperture therethrough.

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.

In one aspect of the present application, a dental appliance for isolating jaws from facial muscles is provided, the dental appliance is substantially in the shape of an elongated plate curved according to dental arches, and is received between the jaws and the facial muscles when it is worn, the dental appliance comprises: buccal shields located at both ends of the dental appliance and configured to isolate posterior teeth from facial muscles; and labial bumpers located in the middle of the dental appliance and configured to isolate anterior teeth from facial muscles, wherein the buccal shields and the labial bumpers form an integral piece.

A lip muscle strengthening device includes: an upper plate inserted into a mouth of a user including a first electrode formed on a bottom surface; a lower plate inserted into the mouth of the user including a second electrode formed on a top surface; an outer support plate adhered to an outer lip of the user and supporting a front end of the upper plate and a front end of the lower plate in a connected state while separating the upper plate and the lower plate from each other; and a pressure recognition unit connected to the first electrode and the second electrode and enabling the user to recognize a closed state of the mouth when the user pushes the upper plate and the lower plate with the upper lip and the lower lip and the first electrode and the second electrode contact each other.

A safety device for motor vehicle includes a flexible hollow annular body including an arched upper base portion, an arched lower base portion and two opposing connection portions connected between the upper and lower base portions at two opposite sides, a flexible arched upper push piece having one end thereof connected to the upper base portion and an opposite end thereof extending toward the lower base portion so that a first elastic space is defined between the body and the upper push piece, and a flexible arched lower push piece having one end thereof connected to the lower base portion and an opposite end thereof extending toward the upper base portion so that a second elastic space is defined between the body and the lower push piece.

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.

A carrying case has first and second clam shell members hingedly connected along one side thereof and defines a interior cavity when in a closed position. At least a portion of an oral device is disposed between the first and second clam shell members with a support member engaging and supporting the oral device such that an intraoral bolus simulator is suspended in the interior cavity free of any engagement with the carrying case. The intraoral bolus simulator may include lubricated patches transformable from a first state, wherein the lubricated patches each comprise water soluble thermoplastic particles suspended in a silicone matrix, to a second state, wherein the water soluble thermoplastic particles are depleted from the silicone matrix. A method of stimulating an oral cavity includes depleting the water soluble thermoplastic particles from the silicone matrix, and presenting a rough surface to the user with the depleted lubricated patches.

The purpose of the present invention is to provide a mouth-opening training device with which continuous rotational movement and anterior sliding movement of the temporomandibular joint can be performed smoothly, the device thereby being capable of guiding the movement of the mandible so as to trace an actual mandibular mouth-opening movement. The mouth-opening training device is provided with: an upper member, the base end of which is grasped and the tip of which can engage with a user's maxilla; a lower member, the tip of which can engage with the user's mandible and a portion of which is in contact with the upper member so as to allow sliding; and a connecting section for connecting the upper member to the lower member so as to allow sliding and allow opening and closing. As the tip of the upper member is opened with respect to the tip of the lower member, the lower member moves in the direction of the tip.

A masticatory muscle exercise device has an upper mouthpiece, a lower mouthpiece and at least one elastic member elastically connecting the upper and lower mouthpieces. A counter is cooperative with the upper and lower mouthpieces so as to sense a number of times that the upper and lower mouthpieces move toward or away from each other. The counter has a magnet mounted on one of the upper and lower mouthpieces and a Hall sensor on the other of the upper and lower mouthpieces.
