<p>A device for measuring oral cavity pressure provided with a pressure measuring probe (1) in which a balloon (4) is held by a balloon base material (5), and a connecting member having an inner cavity for transmitting the pneumatic pressure in the interior of the balloon to a pressure detector (8) via the balloon base material. The connecting member is provided with: a probe attachment member (3) which is connected to the balloon base material in a detachable manner at the tip and which is disposed with a gripping section (3b) on the rear thereof; and a linking tube (6) for connecting the rear end of the probe attachment member with the pressure detector. The balloon is provided with a pressure receiving section (4a) and a tubular section (4b) and is joined to the tip of the balloon base material at the tubular section. The probe attachment member is provided with an angle indicating section (3b) with which it is possible to know a given rotating angle direction around an axis, and the angle formed by the lengthwise direction of the flat balloon and the rotating angle direction indicated by means of the angle indicating section is within a given range when the balloon base material and the probe attachment member are connected. It is possible to stably ensure a reliable and accurate measurement by using a pressure measurement probe that uses a flat balloon.</p> |
