Description

Technical Field

[0001] The present invention relates to the technical field of asthma drug administration, and in particular to a drug administration device for treating bronchial asthma. Background Art

[0002] Bronchial asthma is a chronic airway inflammatory disease. This chronic inflammation is associated with airway hyperresponsiveness and usually presents with extensive and variable reversible expiratory airflow limitation, that is, the muscles in the airway contract, causing the airway to narrow, which in turn leads to difficulty in breathing and indirectly triggers symptoms such as wheezing, shortness of breath, chest tightness, or coughing, and the intensity varies over time. If bronchial asthma is not diagnosed and treated in a timely manner, irreversible airway narrowing and airway remodeling can occur as the disease progresses.

[0003] After retrieval, existing drugs for treating bronchial asthma are generally atomized through a drug administration device to facilitate patients to inhale the drugs; however, due to the fact that the drugs have been mixed and loaded into the bottle in this atomization method of the drug administration device, it is often rendered ineffective due to environmental influences, and the dosage per administration is constant. Now there is a method of pouring the powder in the capsule into a specific inhalation device and then actively sucking it. Not only is the powder in the capsule stable and not affected by the environment usually, but the inhalation amount varies according to the situation and will not inhale too much; however, the triggering speed of this method is slow.
