Muscle pressure measuring instrument for mouth cavity, adapter for mouth cavity muscle pressure measuring instrument, and mouth piece for mouth cavity muscle pressure measuring instrument

摘要

Mouthpieces 12 disposed in a mouth between a lower lip, teeth and gum, for example, are mounted to a force measuring device 11. An outer mouthpiece 16 disposed at the lip side is connected via a connecting shaft 28 to a shaft 26, which is a force measuring portion of the force measuring device 11 while an inner mouthpiece 14 disposed at the side of a tooth row is connected to a main body 34 of the force measuring device 11 via a connecting shaft 22 and a mouthpiece-mounting bracket 38. When the mouthpieces 12 are disposed between the lower lip, teeth and gum and the lips are closed, the outer mouthpiece 16 is pulled by the lip. The force pulling the outer mouthpiece 16 is the lip pressure, and the lip pressure at a rest position and the maximum lip pressure (the pressure of a tongue when the mouthpieces 12 are disposed at the side of a body of tongue) of an examinee are displayed on a display 36 of the force measuring device 11.
