<p>A device for measuring oral cavity pressure provided with: a pressure measuring probe (1) in which a balloon (4) formed from an elastic material is held by a balloon base material (5); a connecting member having an inner cavity for transmitting the pneumatic pressure in the interior of the balloon by being connected thereto with the balloon base material therebetween; and a pressure detector (8) for detecting the transmitted pneumatic pressure by being connected to the rear end of the connecting member. The balloon is provided with a pressure receiving section (2a) which forms a closed space and a tubular section (2b) connected to the interior of the pressure receiving section, and the balloon is joined to the tip end of the balloon base material at the tubular section. The balloon base material is provided with a rib (5c) protruding outward along the outer circumference direction of the balloon-side end. It is possible, by using a pressure measuring probe that uses a flat balloon, to stably ensure a reliable and accurate measurement by inserting an appropriately adjusted balloon into the oral cavity.</p> |
