The present invention is a nasal intubation assist device for assisting placement of a nasal endotracheal tube. The guiding device of the auxiliary device is disposed inside the inner tube of the trachea and has a front end, a rear end and a connecting position, and the connecting position is between the front end and the rear end and adjacent to the front end. In addition, the guard covers the distal end of the inner tube of the trachea and is disposed at the connection position, the guard has a protective surface and a sleeve surface, and the protection surface and the sleeve surface are located between the connection position and the rear end, and the sleeve surface is located Between the protective surface and the guide. Thereby, the use of the soft protective member combined with the guiding member can prevent the direct friction, stab or scratch of the inner tube of the tracheal tube and the nasal mucosa when the inner tube of the tracheal tube passes through the nasal passage, so as to solve the traditional intratracheal tube during the nasal intubation process. When passing through the nasal passages, it rubs against the nasal mucosa to cause bleeding and bleeding of the nasal mucosa.本新型係一種經鼻插管輔助裝置，其用以輔助經鼻氣管內管之置放。此輔助裝置之導引件穿設於氣管內管之內且具有前端、後端及連接位置，連接位置位於前端與後端之間且鄰近前端。此外，防護件包覆氣管內管之遠端且設於連接位置上，防護件具有防護面與套接面，防護面與套接面均位於連接位置與後端之間，且套接面位於防護面與導引件之間。藉此，利用軟質防護件結合導引件可避免氣管內管穿過鼻道時，氣管內管與鼻黏膜之直接摩擦、刺傷或刮傷，以解決傳統經鼻插管過程中，氣管內管通過鼻道時，與鼻黏膜摩擦以致鼻黏膜受傷流血的問題。
