Provided is an administration device having a novel structure with which makes it possible for any user to effectively administer a substance to be administered such as a powdery drug to the site called the olfactory region in the nasal cavity. This device includes: a gas generator; a valve part; an injection cylindrical body 50; a flexible portion 51 formed on the distal side of the injection cylindrical body 50; a nozzle end portion 53 having a discharge port 54; and a posture control projection portion 52. When the posture control projection portion 52 is positioned on the nostril floor, the flexible portion 51 deforms along the contour in the external nostril formed between the nasal septal cartilage and the upper lateral cartilage, while the nozzle end portion 53 is positioned on the nose-dorsum side around the region in the external nostril in which the upper lateral cartilage meets the nasal bone.

The application discloses a shuttle type nasal septum penetrating suture device and a use method thereof, which comprises a suture device body and a driving mechanism, the suture device body comprises a front end suture assembly and a rear end holding assembly, the front end suture assembly comprises a sliding cover plate, a sliding cover plate spring, a driving needle seat, a driving connecting rod, a suture needle and a push rod, the push rod is arranged on the driving connecting rod, the sliding cover plate and the lower cover plate combined structure which can be self-adaptively opened and closed are arranged, in the whole process of placing and withdrawing the device into the nasal cavity, the suture needle is always in the closed protection channel, and the suture needle is automatically windowed and punctured only when the target tissue of the nasal septum is fitted, the circular arc movement track of the suture needle is limited through the arc-shaped groove of the needle seat, the limiting guide of the linear bearing seat and the transmission of the stroke amplification connecting rod are matched, the angle, the depth and the track height of each puncture of the suture needle are unified, the one-time full-layer penetration of the nasal septum mucosa and cartilage can be stably realized, the suture point position is regular, and the stress is uniform.
