Nose vent plug, and nasal mask for anesthesia

Abstract

A nose vent plug, and a nasal mask for anesthesia. The nose vent plug comprises a base (1) and two nasal plugs (2) symmetrically provided on the base (1); the inner edges of the two nasal plugs (2) form a gap (3) into which a nasal septum is embedded; each nasal plug (2) comprises an insertion portion (4) and a pressing portion (5); the outer diameter of the pressing portion (5) is larger than that of the insertion portion (4); the bottom end of the pressing portion (5) is integrally formed on the base (1); the insertion portion (4) is integrally formed on the top of the pressing portion (5); an air hole (6) passing through the pressing portion (5) and the base (1) is provided in the insertion portion (4). The insertion portion (4) of the nose vent plug is shorter, and has fewer parts entering a nostril compared with an existing structure, such that human comfort is improved; moreover, the inner-outer contour shape of the nose vent plug is improved, the inner contour of the nose vent plug is used to fit the nasal septum, the pressing portion (5) is used to plug the nostril, and pressing the base (1) against a nasal cavity can strengthen the air tightness of the nasal cavity, such that on the premise of ensuring human comfort, the air tightness between a ventilation structure and nostrils is improved, thereby avoiding air leakage.
