Un outil de tonification des muscles du menton, du cou, de la machoire, des joues, à partir de la contraction desdits muscles lorsque l'usager exécute le mouvement d'ouvrir et de fermer la bouche, comprenant un anneau élastique rembourré encerclant le visage du haut de la tête jusqu'à sous le menton, auquel sont attachées des ceintures à la hauteur du front, aux côtés du front, au-dessus des oreilles à la hauteur des yeux, en-dessous des oreilles à la hauteur des pommettes, sur les joues à la hauteur du menton; convergeant à un noeud porte-ceinture à la hauteur de la nuque, bouclées chacune à l'une de leurs extrémités à un puissant élastique attaché à l'un des flancs de l'anneau élastique.

A device includes: a controller (722) that converts a pressure value detected by a pressure detector (5) into visual or aural lingual pressure information changed depending on a magnitude of the pressure value; and an information output unit, such as a buzzer (73) and a color display LED (37), that outputs the lingual pressure information in response to a signal from the controller (722). The information output unit outputs lingual pressure information different depending on a pressing force applied on an elastic balloon by a tongue, allowing users such as patients and elderly people to continue a training without being bored.

A facial muscle training too has weight portions (25) provided at the ends of left and right arms (31). A orally held portion (24), which is held by the lips, is provided between the arms (31). The arms (31) vibrate in resonance when the orally held portion (24) is vibrated in the vertical direction at a frequency of less than 6.50 hertz. Accordingly, the weight of the weight portions (25) acts as load on the orally held portion (24) and a facial muscle training effect is achieved.

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 (1) is provided with: an upper member (2), the base end (11) of which is grasped and the tip (12) of which can engage with a user's maxilla; a lower member (3), the tip (12) of which can engage with the user's mandible and a portion of which is in contact with the upper member (2) so as to allow sliding; and a connecting section (5) for connecting the upper member (2) to the lower member (3) so as to allow sliding and allow opening and closing. As the tip (12) of the upper member (2) is opened with respect to the tip (12) of the lower member (3), the lower member (3) moves in the direction of the tip (12).
