Embodiment 2

[0050] Although the realization method in Example 1 can effectively reduce the problems caused by the condensation of exhaled gas in the delivery device and the large amount of medicines getting wet and adhering to the inner wall compared with the insufflation method, There will be some problems in both the invented device and the existing equipment, that is, the problem of drug residue and delivery efficiency. The solution in Example 1 cannot completely solve the problems of drug or gas powder residue and delivery efficiency. This is because, during the drug delivery process, the concentration of the powder in the cavity will gradually decrease as the insufflation proceeds. However, repeated suctions are required to inhale most of the powder into the patient's body through repeated dilution. .

[0051] There are often powder residues in the existing equipment because the existing equipment basically pierces the capsule at the side, and there is inevitably residue in the caps...

Abstract

The invention discloses a self-suction type nasal powder material feeding device. The self-suction type nasal powder material feeding device comprises a shell, a capsule containing cavity, an air inlet, a nasal nozzle, a powder material releasing mechanism and an annular air channel. The capsule containing cavity is formed in the shell and fixed to the middle of the shell in a suspended mode; theannular air channel is formed by the outer wall of the capsule containing cavity and the inner wall of the shell; the powder material releasing mechanism is arranged at the bottom of the shell and used for releasing powder materials in the capsule containing cavity; and the air inlet is formed in a first position of the shell, the nasal nozzle is arranged at a second position of the shell, and a one-way valve which is opened outwards is arranged in the nasal nozzle.

Description

technical field [0001] The present invention relates to devices for administering powdered material to the nasal cavity of a subject, in particular a novel nasal powdered material delivery device. Background technique [0002] Nasal administration is an important and effective way for otolaryngology to treat nasal-related diseases. It can quickly and effectively relieve nasal symptoms. Commonly used clinical nasal administration includes nasal drops, nasal hormones, and nasal decongestants. Wait. [0003] The surface area of ​​the human nasal mucosa is 150 cm 2 , not only there are many microvilli on the epithelial cells of the mucosal surface, which are similar to the small intestinal villi, which can increase the effective area of ​​drug absorption, but also there are abundant capillaries and lymphatic vessels in the subepithelial layer of the nasal mucosa, which can quickly absorb drugs into the human body cycle. The mucosa in the upper part of the nasal cavity is thic...
