Nasal cavity support

The present disclosure relates to a nasal stent configured as a tubular structure capable of being inserted into nostrils, comprising: a tubular support portion for supporting in a nasal meatus; the first expansion part is used for being supported on a nasal septum mucous membrane, and the first expansion part is located at one axial end of the tubular supporting part and expands outwards in the radial direction; the second expansion part is used for being supported in the nasal vestibule, the second expansion part is located at the end, away from the tubular supporting part, of the first expansion part and expands outwards in the radial direction, and an opening is formed in the end, away from the first expansion part, of the second expansion part; the first expansion part, the second expansion part and the tubular supporting part are of a net structure capable of stretching and retracting in the radial direction. By means of the technical scheme, the nasal cavity support can solve the technical problem that
