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

A muscle pressure measuring instrument for mouth cavity, wherein mouth pieces (12) disposed in a mouth cavity, for example, between a lower lip and teeth and gingiva is connected to a force measuring instrument (11), an external mouth piece (16) disposed on a lip side is connected through a connection shaft (28) to a shaft (26) as the force measurement part of the force measuring instrument (11) and an internal mouth piece (14) disposed on a dentition side is connected to the main body (34) of the force measuring instrument (11) through a connection shaft (22) and a mouth piece installation fitting (38), whereby, when the mouth piece (12) is disposed between the lower lip and the teeth and gingiva and the lips are closed, the external mouth piece (16) is pulled by the force of the lips, and the tensile force thus obtained as a mouth lip pressure is displayed on the display part (36) of the force measuring instrument (11).
