MAT FOR PRESSURE MEASUREMENT, AND BIOLOGICAL INFORMATION ACQUISITION DEVICE

摘要

PPROBLEM TO BE SOLVED: To solve the problem, wherein when a distribution of pressures to be applied to an air mat is measured, a plurality of detection points are provided on the air mat and it is necessary to provide sensors for measuring the pressures applied to the air mat at each detection points. PSOLUTION: On a mat for pressure measurement 2, a first medium accommodation body 21b is disposed to the left side, and a second medium housing body 22b is disposed to the right side. The first medium accommodation body 21b is provided with a first connecting pipeline 21a connected thereto, and the second accommodation body 22b is provided with a second connecting pipeline 22a connected thereto. Since the inside diameter K4 of the second connecting conduit 22a is set to be smaller than the inside diameter K2 of the first connecting pipeline 21a and the length of the second connecting pipeline 22a is set to be larger than the length of the first connecting pipeline 21a, the value of the pressure loss coefficient of the second connecting pipeline 22a is larger than that of the first connecting pipeline 21a.
