Double-blister Inhaler

This device contains the formulation for patient use within individual blisters, with a single blister strip containing multiple independent drug-filled blisters.

The user slides the device cover downward, causing the internal gears to rotate. The rotating gears drive and rupture the internal blister. The formulation from the ruptured blister is exposed to the device’s airflow channel. Through inhalation, the powder is carried out by the airflow, achieving pulmonary drug delivery.
