2A1-N02 体動による計測位置ずれ防止機能を持つ血圧脈波計測デバイス(マイクロロボット・マイクロマシン)

Abstract

In this study, we report on the blood pressure pulse wave device with prevention function for measurement position error by body movement. This device consists of a force sensor, a guide, and a acrylic plate for guide height adjustment. We measured blood pressure pulse wave by prototype device before and after ulnar flexion, and calculated the S/N ratio of blood pressure pulse wave. The S/N ratio decreased 30.1 % without a guide. When guide height is 0 mm, the S/N ratio decreased 2.9 %. Since the measurement position error by body movement was prevented by the guide, the decrease in the S/N ratio of blood pressure pulse wave was suppressed.
