Artificial palate device for electropalatograph
First Claim
1. An artificial palate device for use in electropalatograph speech training and the like comprising a flexible electrically insulative base board substantially in the shape and dimensions of a human hard palate, a plurality of tongue contact sensing electrodes provided as spaced from each other on one surface of said base board, a plurality of lead wires corresponding in number to said electrodes and provided on said one surface of the base board, said lead wires being connected respectively at one end to each of the electrodes and led out of the base board as insulated from each other and from other electrodes, and means for covering substantially the said one surface of the base board and having a plurality of through holes made at positions corresponding to those of the electrodes for exposing at least a part of the respective electrodes out of said layer, said device being capable of intimately fitting a human hard palate and being retained therein.

Abstract
An artificial palate device of electropalatographs for electrically detecting and observing dynamic patterns of linguapalatal contacts during speeches by means of many tongue-contact sensing electrodes provided on a tongue-contacting surface of the device fitted intimately to the surface of hard palate of trainees of articulation study and speech training. The electrodes and lead wires connecting the electrodes to an electropalatograph display device are provided on a surface of base board preliminarily prepared with a flat, electrically insulative and flexible plate material and in a shape intimately adaptable when curved to the hard palate. As required, a flat metal foil easily deformable in sectional shape and retainable in its deformed shape is laminated in the other surface of the base board. The lead wires and metal foil are covered by an insulative layer.
