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 present application discloses a method and device for assessing the risk of adenoids hypertrophy and OSA in children based on nasal angle measurement. The device includes: an image acquisition unit for acquiring a side facial image or profile of a child; a nasal tip protrusion angle measurement unit for measuring the nasal tip protrusion angle, that is, the angle between the nasal dorsum tangent line and the nasal inferior margin tangent line; a comparison unit for comparing the measured nasal tip protrusion angle with the nasal tip protrusion angle critical value; a risk assessment unit for assessing the risk of the child suffering from adenoids hypertrophy and OSA when the measured nasal tip protrusion angle is greater than the critical value. The present application provides a simple, non-invasive device for screening the risk of adenoids hypertrophy and OSA in children, which can quickly identify potential risks and provide an important reference for clinical diagnosis and early intervention.

This invention provides a nasal prosthesis, including a nasal dorsum portion. The inner surface of the nasal dorsum portion is recessed inward based on the outer surface of the nasal dorsum portion to form a depression, wherein a support portion is provided within the depression. The nasal dorsum portion of this invention has a relatively thin overall thickness, strong adaptability, and after the product is removed, the newly formed tissue can allow the nose to still maintain a certain height.

The present invention provides a nasal prosthesis, including a nasal dorsum part, the nasal dorsum part at least including a nasal dorsum section and a first connecting section, the nasal dorsum section is willow-leaf-shaped; the first connecting section is located on one side of the nasal dorsum section and connected to the nasal dorsum section as a whole, wherein at least one inwardly recessed shingle connecting portion is formed on the inner side of the first connecting section. The present invention is provided with a shingle connecting portion on the nasal dorsum part to provide a connection space, and has the advantages of low implantation difficulty and good connection effect.
