PROBLEM TO BE SOLVED: To make it possible to expose nostrils while using the guide by moving a nasal exhalation air introducing section (50) to an evacuation position such as when wiping the nostrils (510) of a person (500) to be measured.SOLUTION: Exhalation air introducing guides (50, 60, 70) used for a breathing air concentration measuring sensor (1) for measuring the concentration of specific components in breathing air or a breathing air flow amount sensor comprises a breathing air passage (70) for passing the exhalation air of the person (500) to be measured to the measuring position and the nasal exhalation air introducing section (50) arranged around the nostrils (510) of the person (500) to be measured and introducing the exhalation air from the nose of the person (500) to be measured to the breathing air passage (70) and is characterized in that the breathing air passage (70) and the nasal exhalation air introducing section (50) are connected with each other and the nasal exhalation air introducing section (50) can move between a wearing position covering the surrounding of the nostrils (510) of the person (500) to be measured and the evacuating position where the nostrils (510) are exposed.COPYRIGHT: (C)2010,JPO&INPIT【課題】被測定者(500)の鼻孔(510)を拭う場合などに、鼻呼気導入部(50)を退避位置へ移動させることで使用状態のまま鼻孔を露出させることができる。【解決手段】呼吸気中における特定成分の濃度を測定する呼吸気濃度測定センサ(1)または呼吸気流量センサに用いられる呼気導入ガイド(50、60、70)であって、前記測定位置へ前記被測定者(500)の呼気を通過させる呼吸気通路(70)と、前記被測定者(500)の鼻孔(510)の周囲に設けられ、前記被測定者(500)の鼻からの呼気を前記呼吸気通路(70)へと導入する鼻呼気導入部(50)と、を備え、前記呼吸気通路(70)および前記鼻呼気導入部(50)は互いに接続され、前記鼻呼気導入部(50)は、前記被測定者(500)の鼻孔(510)の周囲を覆う装着位置と、当該鼻孔(510)が露出する退避位置との間を移動可能であることを特徴とする呼気導入ガイド(50、60、70)を提供する。【選択図】図1
