Abstract:
A measuring device comprising a balloon unit (200) placed under the portion to be measured of a patient lying on a bed, a measuring device body (100) for measuring the internal pressure of the balloon unit, and connecting paths (410, 420) for connecting the above two. The balloon unit has a bag−like member (210) having a flat−plate form and an enclosed inner space, and a flat−plate mat (220) disposed inside the bag−like member and constituted of a polyurethane foam. The internal pressure of the balloon unit placed under a patient is measured by a pressure sensor inside the measuring device body to be displayed on a display unit (110). A 3−way cock (300) is provided in the middle of the connecting paths to form a side−wise branch path, to which a syringe (500) is connected for regulating the internal pressure before measuring.
