Tongue suction restrainer, tongue suction restrainer manufacturing kit, and method of manufacturing tongue suction restrainer

A tongue suction restrainer, comprising:

• an upper fixing portion that is fixable to an upper jaw of a user when the tongue suction restrainer is attached to an oral cavity of the user;
• an annular abutment portion that abuts a hard palate of the user when the tongue suction restrainer is attached to the oral cavity;
• a recess that is formed at an inner side of the abutment portion to form a closed space with the hard palate in a state in which an entire circumference of the abutment portion abuts the hard palate;
• a suction portion that communicates with the recess to apply a negative pressure to the closed space from an outside;
• and
• a tongue suction portion that is formed at a position facing a tongue of the user when the tongue suction restrainer is attached to the oral cavity, that has a suction hole provided to communicate with the recess, and that sucks the tongue by the negative pressure,
• a lower fixing portion that is fixable to a tooth of a lower jaw of the user, and
• a protrusion that protrudes from an inner peripheral portion of the lower fixing portion to form a pocket for allowing a part of the tongue to enter between the protrusion and the tongue suction portion,
• wherein the suction hole is provided in a portion of the lower fixing portion which forms the pocket.

A tongue suction restrainer manufacturing kit, comprising:

• an upper fixing portion material for forming an upper fixing portion that covers and is fixed to a tooth of an upper jaw of a user from a tooth mold of the upper jaw of the user, and forming an annular abutment portion that abuts a hard palate of the user, and a recess that forms a closed space with the hard palate at an inner side of the abutment portion in a state in which an entire circumference of the abutment portion abuts the hard palate;
• a tongue suction portion material that is attached to a back surface side of the recess and that forms a tongue suction portion facing a tongue of the user;
• and
• a lower fixing portion material for forming a lower fixing portion that is attached to a lower jaw side of the upper fixing portion and that covers and is fixed to a tooth of a lower jaw of the user, wherein a suction hole communicating from the recess to the tongue suction portion and a suction portion communicating with the recess to apply a negative pressure to the closed space from an outside are formed.
