PROBLEM TO BE SOLVED: To provide a device for holding an upper limb for blood vessel parameter measurement of living body, capable of improving measurement accuracy when measuring a blood vessel parameter.SOLUTION: On a base 74 to which a first support part 82 and a second support part 84 projected to the upper side at a prescribed interval are fixed, a movable support member 76 integrally having a first receiving member 96, second receiving members 102 and 137 and a connection part 104 for connecting the first receiving member 96 and the second receiving members 102 and 137 is supported so that one end part and the other end part thereof can be turned by the first support part 82 and the second support part 84, and a turning fixing device 78 capable of fixing the movable support member 76 at any turning position is provided. Thus, by fixing the movable support member 76 by the turning fixing device 78 at the turning position at which measurement signals obtained from a hybrid probe unit 24 have a few noise patterns 134, highly accurate measurement is performed when measuring the blood vessel parameter of a living body 16.COPYRIGHT: (C)2009,JPO&INPIT【課題】血管パラメータの測定に際して測定精度を高めることができる生体血管パラメータ測定用上肢保持装置を提供する。【解決手段】所定間隔を隔てて上側へ突き出す第1支持部82および第2支持部84が固設された基台74に、第1受部材96と第2受部材102、137とその第1受部材96および第2受部材102、137を相互に連結する連結部104とを一体的に備えた可動支持部材76が、その一端部および他端部が前記第1支持部82および第2支持部84により回動可能に支持されるとともに、その可動支持部材76をいずれの回動位置でも固定可能な回動固定装置78が設けられるので、可動支持部材76をハイブリッドプローブユニット24から得られる測定信号がノイズパターン134の少ない回動位置にて、上記回動固定装置78で固定することにより、生体16の血管パラメータの測定に際して高い精度の測定が可能となる。【選択図】図6
