Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a drug delivery device for inhalation drugs. Background Art

[0002] A commonly used drug treatment for chronic obstructive pulmonary disease is to inhale the drug into the lungs through a drug delivery device, where it is absorbed and treated.

[0003] For example, Chinese patent CN215426708U discloses a dry powder inhalation device, which is provided with a medicine placement chamber, an airway and a suction nozzle. When in use, the capsule medicine in the medicine placement chamber is punctured, and then the powder medicine is inhaled through the suction nozzle.

[0004] However, when using the device, it is difficult for the user to control the position of the nozzle, and there is a risk of non-standard inhalation posture, which may cause the medicine powder to enter the throat and not flow through the trachea to the lungs, resulting in waste. The inhalation and inhalation effect of the medicine powder are not guaranteed, and the user needs to inhale more vigorously, while some patients find it difficult to perform heavy breathing.
