Normal stress distribution measuring device null of tongue - palate

摘要

PURPOSE:To provide a vertical-stress-distribution measuring device for a tongue- palate contact surface, which can measure the contact position of the tongue and the palate and the vertical stress of the contact surface at the same time in order to analyze a human jaw-mouth function, especially, the force control function of the tongue. CONSTITUTION:A vertical-stress-distribution measuring apparatus for a tongue- palate contact surface has an artificial palate floor 1 and a force sensor 2. The artificial palate floor 1 is formed in close contact with the palate surface, and a hole 10 is opened in correspondence with a position, where the vertical stress of the tongue-palate contact surface is measured. In the force sensor 2, a strain sensor 5 is fixed at the central part of the surface of a flexible thin plate 4, and a transmitting rod 7 is fixed at a position corresponding to the strain sensor 5 at the rear surface of the thin plate 4. Both ends of the thin plate 4 are fixed to the inner side of the artificial palate floor 1, and the force sensor 2 is assembled into the artificial palate floor 1.
