Summary:The present invention relates to a drug injecting device for injecting a drug to a nasal cavity and a paranasal cavity through a nostril. The present invention is made of an elastic material to facilitate compression and restoration, and mounts an adaptor having a storing space therein on a discharging unit of a drug storing container. The present invention fills the drug in the nasal cavity by injecting the drug stored in the drug storing container to the nasal cavity through the adaptor, and changes volume of the adaptor by repeatedly compressing and releasing the drug storing container to the adaptor. A volume change amount of the adaptor generates turbulence or sloshing in the drug filled in the nasal cavity. The generated turbulence or sloshing promotes touch of nasal cavity surface with the drug, and drug flow to the paranasal cavity. Therefore, the present invention can increase a cleaning effect for a nasal cavity and paranasal cavity surface and a drug injecting effect, and nasal cavity disease preventing and treating effects. 본 발명은 콧구멍을 통해 비강 및 부비동으로 약물을 주입하는 약물 투여장치에 관한 것으로서, 더 상세하게는 탄성재질로 형성되어 압축과 복원이 이루어지고 내부에 수용공간이 형성된 어댑터를 약물저장용기의 배출부에 장착하고, 약물저장용기에 저장된 약물을 어댑터를 통해 비강으로 주입하여 비강에 약물이 채워지도록 하고, 이 상태에서 약물저장용기를 어댑터측으로 가압 및 해제를 반복하여 어댑터의 체적을 변화시키고, 어댑터 체적변화량은 비강속에 채워진 약물에 난류 또는 출렁임을 발생시키고, 발생된 난류와 출렁임은 약물의 비강표면 접촉과 부비동으로의 약물 흐름을 촉진시켜 비강과 부비동 표면 세척 및 약물 투여 효과를 높일 수 있고 비강질환 예방과 치료의 효과를 높일 수 있는 비강 및 부비동 약물 투여장치에 관한 것이다.
