Definitions

  • the present invention relates to apparatus for stimulating muscles in the floor of the oral cavity of a subject, and in particular for stimulating at least some of the muscles which control the tongue, such as the genioglossus muscles, the mylohyoid and geniohyoid muscles, digastric muscles and the plathysmus muscles.
  • the muscles which control the tongue of a subject are the longitudinalis superficialis and profundus, transversus and verticalis linguae. These muscles form the body of the tongue, and together with the in-growing muscles genioglossus, hyoglossus, styloglossus and palatoglossus control the three-dimensional movement of the tongue.
  • the muscles genioglossus and geniohyoideus in general, are considered to be the muscles which are responsible for urging the tongue forward, and thus, in general, it is believed that by maintaining these muscles adequately toned, sleep apnoea in a subject can be significantly reduced, and in many cases eliminated.
  • weakening of the muscles of the floor of the mouth may also result in a condition known as a double chin. This is also undesirable.
  • U.S. Patent Specification No. 5,190,053 of Meer discloses an intra-oral sublingual electrode device for the electrical stimulation of the genioglossus muscle to maintain the upper airway open in the treatment of sleep apnoea.

  • a third electrode is located externally of the oral cavity beneath the floor of the oral cavity for co-operating with the two electrodes located in the oral cavity, so that when an EMF is developed across the external electrode and the electrodes in the oral cavity a current flows through the floor of the oral cavity for stimulating the genioglossus muscle.
  • the device of Meer suffers from a number of disadvantages, in that firstly, due to the location of the electrodes in the oral cavity considerable discomfort is caused to the subject since stray currents are routed to the gums of the subject, which is undesirable.
  • a second and more important disadvantage of the device of Meer is that it is limited in the muscles which can be stimulated, since the electrodes in the oral cavity are located adjacent the gums of the lower jaw of the subject.

Abstract

L'invention concerne un appareil (60) pour stimuler les muscles qui commandent le fonctionnement de la langue (28) d'un sujet. Cet appareil comprend un élément de mise en prise avec le menton (62) qui supporte une électrode externe (8) en vue de son positionnement externe au-delà du plancher buccal (9) du sujet. Un support (3) d'électrode buccale s'étend à partir de l'élément (62) de mise en prise avec le menton pour placer une électrode buccale (64) dans la cavité buccale (4). Un élément de positionnement (10) positionne le support (3) d'électrode sur les dents de la mâchoire inférieure du sujet tandis qu'un élément de support (65) s'étend à partir de l'élément de positionnement (10) pour supporter l'électrode buccale (64) à une extrémité distale de ce dernier. L'électrode buccale (64) est constituée d'un polymère de silicone électriquement conducteur pour assurer la mise en prise électrique de la langue (28) sur le dessous de celle-ci et pour assurer la mise en prise électrique (9) avec le plancher (9) de la cavité buccale (4). L'électrode buccale (64) est placée dans la cavité buccale (9) espacée de la gencive (12) de la cavité buccale, à une distance suffisante pour empêcher les courants vagabonds de pénétrer dans la gencive inférieure et les dents (11) du sujet. Un signal d'impulsion provenant d'un générateur de signaux (34) est appliqué par un connecteur de douille (71) aux électrodes buccale et externe (64, 8) pour faire passer un courant dans les nerfs moteurs des muscles qui commandent le fonctionnement de la langue (28) pour stimuler les muscles, et à leur tour, pour tonifier et renforcer les muscles. En renforçant les muscles, on maintient la langue dans un état plus avant dans la bouche, ce qui éviter l'apnée du sommeil et le ronflement. L'appareil (1) tonifie les muscles du plancher (9) de la cavité buccale (4), ce qui remédie du point de vue cosmétique à l'état du double menton.
