Problems solved by technology

[0004] Although the structure of existing inhalation devices is relatively simple, there are common problems such as unstable powder delivery, easy powder residue, poor sealing (for example, powder is easy to be damp in a humid environment), unfriendly design, and complicated assembly process.
Among them, unstable powder delivery volume and easy powder residue will lead to insufficient dosage, so that the powder cannot achieve the expected curative effect
In addition, powder residues in the inhalation device can also contaminate the inhalation device, thereby causing certain hazards to the user

Abstract

The invention relates to an inhalation device, and relates to the technical field of medical instruments. The inhalation device comprises a housing, a containing cabin and a spacer. The housing comprises a channel for inhaling powder. The containing cabin is arranged within the housing and comprises an opening for communication with the channel, and the opening remains aligned with the channel. The spacer is configured to be capable of moving between a first position and a second position relative to the containing cabin, in the first position, a first part of the spacer is located between the opening and the channel to close the opening of the containing cabin, so that the opening does not communicate with the channel, and in the second position, the spacer exposes the opening of the containing cabin, so that the opening communicates with the channel.

Description

technical field [0001] The present disclosure relates to the technical field of medical appliances. In particular, the present disclosure relates to an inhalation device. Background technique [0002] Chronic obstructive pulmonary disease is a chronic bronchitis or emphysema characterized by airflow obstruction that can progress to a common chronic disease of cor pulmonale and respiratory failure. Chronic obstructive pulmonary disease is related to abnormal inflammatory response caused by harmful gases and particles, and has a high disability and mortality rate. The global incidence rate of people over 40 years old has reached as high as 9% to 10%. [0003] At present, pulmonary inhalation administration and nasal inhalation administration are effective treatments for chronic obstructive pulmonary disease, which have the characteristics of targeting, high efficiency, quick effect, and less toxic and side effects. In addition, pulmonary or nasal inhalation administration is...
