< Topic >Exchanging station possible pernasality intubation is offered.SolutionsEnd of feed pipe A it is joined by the side wall of the component 50 for intubation, where two intubations 52 form by strengthening flexibility tube 30 the destal the component 50 for intubation, it is provided in band 60 for fixing of point section which is connected by holddown, with the band 60 for fixing of point section holddown component 50 for intubation stably blocks the edge of component 50 for intubation before the human body point section facilities point shift, with plug part 53 makes exchanging station possible pernasality intubation form. The Interpolation making two intubations 52 the human body nostril wear, the intake air point to the oxygen, to adjust to the position of oxygen source, plug part it makes the lightweight point intubation form where the cubic measure which makes the position of 53 and strengthening flexibility tube exchange 30 is small, adjusting to the environment of the patient with the single pipe conduit air-supplied structure of point intubation, it makes the inhalation direction of oxygen adjust, it makes the purpose achieve which raises the comfort when using the patient.< Choice figure >Drawing 3【課題】位置交換可能な経鼻挿管を提供する。【解決手段】送り管Aの末端が強化可撓管30により2つの挿管52が成形される挿管用部材50の側壁に結合され、挿管用部材50は端部が締め具により連接される鼻部の固定用バンド60に設けられ、鼻部の固定用バンド60により締め具は挿管用部材50を人体鼻部の前に安定的に固設させ、栓部53により挿管用部材50の端を閉塞し位置交換可能な経鼻挿管を形成させる。2つの挿管52を人体鼻孔に挿着させて酸素を入気させ、酸素源の位置に合わせ栓部53及び強化可撓管30の位置を交換させる体積の小さい軽量な鼻挿管を形成させ、鼻挿管の単管路送気構造により患者の環境に合わせて酸素の吸入方向を調整させ、患者の使用時の快適性を高める目的を達成させる。【選択図】図3
