Blister-based Dry Powder Inhaler

Patent number: CN201911132049.1

This inhaler contains blister strips and a device body. One dose of medicine is enclosed inside one blister strip. When in use, the users place one blister strip inside the specific place of the device and peel off the surface of the blister strip to complete the process of drug loading and pulmonary drug delivery. The drug powder channel of the device is designed based on aerodynamics. With the help of the vortexes and collisions generated inside the channel, the drug particle dispersion, de-agglomeration, and lung deposition rate can be effectively improved.
