PROBLEM TO BE SOLVED: To achieve a measuring instrument of oral cavity-related pressure which is handled safely and easily with high accuracy, and to achieve a measuring instrument of oral cavity-related pressure which is easy to carry, consuming less power, and operable on a battery. SOLUTION: In the measuring instrument of oral cavity-related pressure, at a place for sorting to a side where a probe, a pressure sensor and a pressurizing pump whose pressurizing speed can be controlled and which is driven by a pulse width modulation system are communicated and a side where a pressurizing pump, a safety valve and an exhausting apparatus are communicated, an air path shut off apparatus is arranged for stopping the pressurizing pump and exhausting air in abnormality during pressurization. IN rehabilitation performed with the tongue, reference of counting the number of times of repeating can be displayed on a display means. At the hollow body of the probe, a net for preventing swelling over a fixed value is provided or a water feeding means integrally fitted to the probe is provided. COPYRIGHT: (C)2007,JPO&INPIT
