摘要：
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.La présente invention concerne un dispositif d'injection de médicament liquide pour injecter un médicament liquide dans une cavité nasale et des sinus paranasaux à travers une narine et, plus particulièrement, un dispositif d'injection d'un médicament liquide dans une cavité nasale et des sinus paranasaux, le dispositif étant caractérisé en ce que : un adaptateur, qui est formé d'un matériau élastique de telle sorte qu'une compression et une restauration peuvent être effectuées et qui a un espace de réception à l'intérieur de celui-ci, est monté au niveau d'une partie de décharge d'un récipient de stockage de médicament liquide； un médicament liqu
