Abstract:
The present invention relates to a liquid drug injection device for injecting a liquid drug into a nasal cavity and paranasal sinuses through a nostril and, more specifically, to a device for injecting a liquid drug into a nasal cavity and paranasal sinuses, the device being characterized in that: an adaptor, which is formed of an elastic material such that compression and restoration can be carried out and which has an accommodation space therein, is mounted at a discharge part of a liquid drug storage container; a liquid drug stored in the liquid drug storage container is injected into the nasal cavity through the adaptor so as to fill the nasal cavity with the liquid drug; while the nasal cavity is filled with the liquid drug, the liquid drug storage container is repeatedly pressed toward the adaptor and released so as to change the volume of the adaptor; the change in the volume of the adaptor generates turbulence or sloshing of the liquid drug filled in the nasal cavity; and the generated turbulence and sloshing promotes the liquid drug to contact the surface of the nasal cavity and flow toward the paranasal sinuses so as to enhance the effect of cleaning the surfaces of the nasal cavity and the paranasal sinuses and injecting the liquid drug, and to increase the effectiveness of preventing and treating nasal diseases.
